摘要:
A connector in which the deformation of lock portions is prevented, and the connector can have a compact design, and housings are prevented from being displaced with respect to each other in both longitudinal and transverse directions. Transverse grooves of a dovetail shape are formed respectively in widthwise opposite ends of an upper surface of a lower housing at a front end portion thereof, and longitudinal grooves of a dovetail shape are formed in a widthwise central portion of this upper surface. Transverse ribs of a dovetail shape are formed respectively at widthwise opposite ends of a lower surface of an upper housing at a front end portion thereof, and longitudinal grooves of a dovetail shape are formed on a widthwise central portion of this lower surface. The transverse ribs are greater in projecting height than the longitudinal ribs. When the ribs are press-fitted respectively into the associated grooves, the two housings are locked together. When an external force of above a predetermined level is applied so as to separate the two housings from each other, the ribs are withdrawn respectively from the grooves, thereby disconnecting the two housings from each other.

Upper and lower connector housings are respectively formed substantially in a box shape having upper and lower walls. The upper and lower connector housings are connected to each other by overlapping an upper wall of the lower connector housing and a lower wall of the upper connector housing in an opposing state. Engaging holes are respectively formed on the lower wall of the upper connector housing and the upper wall of the lower connector housing. The engaging hole of the upper connector housing is closed by the upper wall of the lower connector housing. The engaging hole of the lower connector housing is closed by the lower wall of the upper connector housing. Accordingly, the terminal can be securely prevented from coming out from the terminal receiving chamber and the adjacent terminals can be securely prevented from being shorted.

A press-connecting terminal including a contact portion provided on one side of a bottom wall so as to be connected to a partner terminal, a caulking portion provided on the other side of the bottom wall for caulking an electric wire, and a press-connecting portion provided between the contact portion and the caulking portion so that an end of the electric wire is press-connected to the press-connecting portion. The press-connecting portion is formed into a frame constituted by a pair of press-connecting blades and a pair of side walls for connecting respective ends of the press-connecting blades to each other through the side walls, each of the press-connecting blades being constituted by an inner press-connecting blade portion and an outer press-connecting blade portion which are put on top of each other, one of the side walls being constituted by a single continuous wall portion, the other of the side walls being constituted by a plurality of wall portions engaged with each other at an intermediate portion of the other side wall to thereby improve the strength of the press-connecting portion.

A connector conduction tester includes a conduction testing section and a connector holding section which are arranged on a stand frame and an operating section for moving the conducting testing section towards the connector holding section, in which a conduction testing operation is carried out with testing pins of the conduction testing section abutted against terminals in a connector. In the tester, the stand frame has a spacer supplying hole which is confronted with a spacer inserting hole formed in a connector set in the connector holding section, and spacer pushing device located below the spacer supplying hole. Furthermore, a conduction testing method in which a connector is set in a connector holding section and a conduction testing section is moved, so that the conduction of terminals in the connector is tested with testing pins, in which a spacer is supplied to a spacer supplying hole in a stand frame which hole is confronted with a spacer inserting hole formed in the connector, and when the connector is engaged with the conduction testing section, the spacer is pushed into the spacer inserting hole from the spacer supplying hole with the aid of pushing device.

A terminal retaining structure for a doubly retainable electrical connector comprises a terminal retaining member 3 having overhang wall portions 6a, 6b and terminal retaining projecting plates 7a, 7b projecting forward from the overhang wall portions 6a, 6b for contacting projecting pieces 32 of a terminal 23; and a connector housing 1 having a bottom wall 17 with an opening 13 for inserting terminal retaining member 3 in bottom wall 13 and a flexible retaining lance 20, for retaining terminal 23, having a pair of contact stepped portions 27 formed on opposite side portions corresponding to the pair of terminal retaining projecting plates 7a, 7b for contacting the projecting pieces of terminal 23. When terminal 23 is inserted in connector housing 1 and terminal retaining member 3 is inserted in bottom wall 13, the pair of contact stepped portions 27 contact projecting pieces 32 of terminal 23, and the pair of terminal retaining projecting plates 7a, 7b simultaneously contact projecting pieces 32 of terminal 23 and the pair of contact stepped portions 27, thus preventing deformation of the flexible retaining lance 20 and separation of terminal 23 from connector housing 1.
摘要:
Both a method of assembling a connector and a connector housing usable for executing the method are provided. In the method, the connector housing moulded as one body is prepared at first. The housing consists of a housing body with an opening, a cover for closing the opening and a connecting piece for connecting the connector housing with the cover. Then, a wire is installed into the body through the opening. Next, the connecting piece is cut, so that said cover is separated from said housing body. Thereafter, the separated cover is slid into said housing body on the opening, so that it is covered with the cover. To facilitate the sliding of the cover, the housing body is provided with a sliding groove while the cover is provided with a projection to be engaged with the groove.

Using a dry film resist that is a photosensitive resin, a resin mask layer is formed around electrodes on a substrate. A solder precipitating composition is applied on the substrate, and this solder precipitating composition is heated to precipitate solder on the surface of the electrodes. Subsequently, in removing the resin mask layer, at least one selected from glycol ethers and aminoalcohols is used. Thereby, the resin mask layer is removed after heating process. This makes it possible to easily remove the heat-processed resin mask layer in a short period of time without damaging solder resist and solder bumps on the substrate.
