A junction box includes a cable connecting box, a cover covering the cable connecting box and a cable electrically connecting with the cable connecting box. The cable connecting box including an insulative box and a wire connecting module, the insulative box comprising a plurality of walls extending upwardly and a receiving cavity surround by the walls, the walls including a front wall defining a plurality of mounting holes for the cable passing through. The cover includes a plurality of separating walls extending downwardly from a peripheral of the cover to engage with the walls of the insulative box and a pretending wall being parallel to the separating wall and located in front of the front wall. The adding pretending wall provides a longer distance for the junction box to ensure a safe creepage distance for the user to use the junction box.

A junction box includes a cable connecting box including an insulative box and a wire connecting module assembled to the insulative box. The insulative box has a receiving cavity, a bottom wall under the receiving cavity, a plurality of walls surrounding around the receiving cavity, at least a supporting portion located in the walls, a locking slot defined between the supporting portion and one of the walls, and a resilient locking portion received in the locking slot. A cover covers the cable connecting box and comprises a latching portion protruding outwardly from a side of the cover to lock with the resilient locking portion in the locking slot. In this arrangement, the junction box is convenient for users service.

A junction box includes a cable connecting body and a cover covering the cable connecting body. The cable connecting body includes an insulative block, a plurality of connecting foils retained in the insulative block and a plurality of diodes connecting with two neighborly connecting foils. The connecting foils are insert-molded with the insulative block. The insulative block has a hook and the cable connecting body has a front wall with a depressing slot corresponding to the hook. The hook and the depressing slot engage with each other, when the insulative block is damaged, the user can remove the insulative block away from the junction box by levering the hook.

An electrical connector (100) includes an insulative housing (1), a front shell (4) and a back shell (5) fixed to the insulative housing (1) and a set of contacts (2) received in the insulative housing (1). The back shell (5) includes a base (51) covering a rear surface of the insulative housing (1) and formed with mating plates (512). The insulative housing (1) has two guide slots (173) extending forwardly from a back face (17) of the insulative housing (1). The back shell (5) is assembled to the insulative housing (1) from top-to-bottom, the guiding slot (173) guides the mounting plate (512) and finally receives the mounting plate (512) to retain the back shell (5).

A junction box includes a cable connecting box and a cover covering the cable connecting box. The cable connecting box includes an insulative block, a plurality of contacting foils retained in the insulative block and a plurality of diodes. Each diode connects with two neighborly contacting foils. The contacting foils are insert-molded with the insulative block. Based on thermal radiation properties of the plastic material is superior to that of the metal material, as the contacting foils transfer the heat to the insulative block, the insulative block would deliver the heat to the cable connecting box, then the heat would be delivered to the cover. Such that, the heat dissipates outside quickly from the junction box.

A junction box includes a cable connecting box, a cover covering the cable connecting box and an o-ring sealing between the cover and the cable connecting box. The cable connecting box includes an insulative block, a plurality of contacting foils retained in the insulative block, a plurality of diodes connecting with two neighborly contacting foils and four walls surrounding around the insulative block. The cover defines a sealing slot for receiving the o-ring. The sealing slot has a bump at a place of the molding joint of the cover to enlarge a deformation of the o-ring for improving a waterproof effect of the junction box.

An electrical connector (100) has a first end for fitting with another connector and a second end for connecting to a board. The connector comprises an insulative housing (1), a number of contacts (2) and a metal shield (3) enclosing the insulative housing. The insulative housing includes a tongue plate (11) with a number of passageways (110) defined therein for receiving the contacts. The contacts are arranged side by side in the first end and arranged in three parallel rows in the second end. The contacts include signal contact pairs (21) and grounding contacts (22) disposed adjacent to and separating the signal contact pairs. Each signal contact pair includes a first signal contact and a second signal contact being substantially in equal length of the first signal contact. The signal contact pairs have matched impedance for transmitting high-speed signals, thereby canceling any cross talk therebetween.

An electrical connector (100) includes an insulative housing (1) defining a number of passageways (121) for receiving corresponding contacts (2), and a metal shield (3) enclosing the insulative housing (1). The metal shield has a top face (31), a bottom face (32) and a pair of side faces (33). The bottom face includes a pair of first board mounting legs (325) downwardly and a slot (326) between the first board mounting legs (325). The first board mounting legs (325) are disposed in communication of the slot (326) and mounted on a printed circuit board (4). The length of the slot (326) is equal to the total length of the first board mounting legs (325). With the addition of the first board mounting legs (325), the connector (100) can be more stably mounted on the printed circuit board.
