Abstract: A screw retaining mechanism includes a hollow stud and a nut is matched with the hollow stud. The hollow stud has a plurality of elastic plates extending from a free end thereof and along a peripheral wall thereof. An opening is located between two adjacent elastic plates. An inner wall of the nut has a plurality of tubers protruding in the axial direction to match into the opening. The elastic plate defines a first side face and a second side face opposite to the first side face. Said first side face is used to guide the tubers into the opening and the second side face prevent the tuber fall off from the stud.

Abstract: 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.

Abstract: A junction box (100) includes a cable connecting box, a cover (2) covering the cable connecting box, and a cable (4) connecting with the cable connecting box. The cable (4) connecting box has an insulative block (5), a number of contacting foils (6), and a number of diodes (31) connecting adjacent contacting foils (6). The junction box (100) further includes a plurality of clips (9) mounted in the insulative block (5) and electrically connecting with the contacting foils (6). The clip (9) includes a clamp spring (91) and an elastic plate (92) received in the clamp spring (91) to resist the clamping spring (91). As a result, the clamp spring (91) will not resist the cable connecting box so as to improve an using life of the junction box (100).

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
