A connector is provided with a highly reliable lock arm. The connector includes a slider (20) formed to move between a displacement permitting position to a forcible displacement position. The slider (20) and a lock arm (17) are provided with pushing portions (24) and a pushable portion (18), respectively. When the slider (20) is moved from the displacement permitting position to the forcible displacement position with connector housings (10, 40) fitted with each other, slanted surfaces (24A) of the pushing portions (24) push a slanted surface (18A) of the pushable portion (18) to forcibly displace the lock arm (17) to an unlocking position. Since it is not necessary to provide a locking portion of the lock arm (17) and the female connector housing (40) with an unlocking function, reliability of a locking function by the lock (17) can be improved.

A rubber stopper is provided at a rear end of a housing. A receiving tool-insertion opening is formed on a bottom surface of a cavity of the housing such that the receiving tool-insertion opening is located immediately forward from the rubber stopper. A receiving portion is projectingly formed on a lower part of a pressure die. When the housing accommodating a pressure-connection terminal is placed on the lower part, the receiving portion projects upward through the receiving tool-insertion opening, and the apex of a mountain portion is located in the vicinity of an insertion hole of the rubber stopper. When a pressure tool installed on an upper part of the pressure die moves downward, a front end of an electric wire is pressed against and connected with a pressure blade. As a result, the electric wire projecting from the rubber stopper is stretched downward. In this case, a root portion of the electric wire is received with the receiving portion. Thus, the insertion hole of the rubber stopper is not subjected to the stretching force. Consequently, the insertion hole can be prevented from deforming, which provides sealing performance in the periphery of the electric wire securely.

When two connector housings are half-fitted together, a fitting detecting connector causes one of the connector housings to be pushed in a direction of separation by means of springs which are provided within a female connector housing, a spring holder being inserted into this female connector housing so that it can move in an anterior-posterior direction. This spring holder houses springs and, when the two connector housings are being fitted together, a locking arm rises over a stopping protrusion. As a result of the locking arm rising, the spring holder is restrained, its movement in a posterior direction is regulated, and the springs are compressed. When the connector housings are completely fitted together the locking arm springs down, releasing the spring holder, and allowing it to move in a posterior direction under the spring force. All of the half-fitting detector components are provided on one of the connector housings; the other connector housing requires no modification.

A connector is provided to increase the strength for stopping a forward movement of a terminal fitting. The connector has a housing 11 with a cavity 12. A locking portion 18 is disposed in the cavity 12. Opposite side surfaces of a portion of a locking portion 18 more toward the leading end thereof than a locking projection 19 are cut off to form cut surfaces 21. Contact portions 23 projecting inward are formed continuously with a front wall 13 in areas of side surfaces of the cavity 12 facing the cut surfaces 21. Stabilizers 8 provided on a male terminal fitting 1 can come into contact with the back edges of the contact portions 23. A forward movement of the male terminal fitting 1 properly inserted is stopped by the contact with the front wall 13 and the contact of the stabilizers 8 with the contact portions 23. Since the contact portions 23 are formed taking advantage of spaces obtained by cutting off parts of the locking portion 18, they do not cause any enlargement of the cavity 12. Further, this portion of the locking portion 18 toward the leading end thereof from the locking projection 19 has almost no influence on the strength for locking the terminal fitting 1 so as not to be withdrawn backward, and the same degree of a locking force against the backward movement of the terminal fitting 1 as the locking portion of the prior art connector described above can be secured.

A spring holder 25 containing coiled springs 41 is installed in a female housing 11. When a male housing 1 and this female housing 11 are fitted together, a locking arm 20 rises over a stopping protrusion 7, a restraining wall 39 simultaneously engages a locking claw 22, and the coiled springs are compressed. The locking claw 22 makes contact with a contacting face of the restraining wall 39, this contacting face being a tapered face 40. When the locking arm 20 is about to pass over the stopping protrusion 7 to return to its original position, the restraining wall 39 receives a spring force F from the coiled springs and pushes the locking arm 20. A component force F1 in a returning direction of the locking arm 20 is obtained from this spring force F due to the tapered face 40. The component force F1 and the returning force of the locking arm 20 itself cause the locking arm 20 to return smoothly, and the locking arm 20 thus engages with the stopping protrusion 7.

A connector housing is provided to prevent a locking portion from being excessively deformed when the insufficient insertion of a terminal fitting is detected. Cavities 3 are provided in two stages in the connector housing, and locking portions 11 are arranged back to back to share deformation permitting spaces 16. The upper and lower locking portions 11 are arranged such that the longitudinal axes thereof are transversely offset to each other. Detecting portions 23 to be inserted into the deformation permitting spaces 16 project from a retainer 20. At the left and right ends of an inserting end surface 24 of each detecting portion 23, excessive deformation preventing portions 25 are formed symmetrically with respect to vertical direction. The excessive deformation preventing portions 25 can individually come into contact with leading ends 13 of the upper and lower locking portions 11. If a female terminal fitting 8 is insufficiently inserted as in the upper stage of FIG. 7, the retainer 20 may further deform the locking portion 11 after coming into contact therewith, while being inserted. However, the excessive elastic deformation of the locking portion 11 is restricted by the leading end 13 thereof being brought into contact with the excessive deformation preventing portion 25 at the lower side.

When two connector housings are half fitted together, a fitting detecting connector causes one of the connector housings to be pushed in a direction of separation by means of springs which are provided within a female connector housing 5, a spring holder 15 being inserted into this female connector housing 5 so that it can move in an anterior-posterior direction. This spring holder 15 houses coiled springs 16 and, when the two connector housings are being fitted together, a locking arm 11 rises over a stopping protrusion 2. As a result of this rising up the spring holder 15 is engaged, its movement in a posterior direction is regulated, and the coiled springs 16 are compressed. When the connector housings are completely fitted together the locking arm 11 again moves, releasing the engagement of the spring holder 15, and the spring holder 15 is pushed in a posterior direction by the spring force. In this way the separating force does not act when the connector housings are fully engaged.
摘要:
A stabilizer (30) of a terminal fitting (20) is divided into a front stabilizer (31A) and a rear stabilizer (31B) and defining a small clearance therebetween. Thus, the smaller holes (32A, 32B) are formed by the divided stabilizer (30), and external matter is less likely to intrude.
摘要:
A terminal fitting (T) has a rectangular tube (10). A resilient locking piece (25) is accommodated in a rectangular tube portion (10) and a locking hole (19) in the tube (10) exposes the resilient locking piece (25). A side plate (13R) of the rectangular tube (10) is provided with an intrusion restricting portion (21) near the resilient contact piece (25) and in an opening area of the locking hole (19). Thus, the intrusion of an external matter through the locking hole (19) can be restricted by the intrusion restricting portion (21), thereby preventing the interference of the external matter with the resilient contact piece (25).
