Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as Figure 1-3 The photovoltaic junction box connector of this embodiment includes: the metal electrode 11 connected to the cable 13 at the rear end is arranged in a joint body 12, and a tightening nut 14 threaded on the above-mentioned cable 13 is screwed to the end of the above-mentioned joint body 12. Rear end: a limiting sleeve 15 is supported between the metal electrode 11 and the tightening nut 14 to prevent the metal electrode 11 from being pulled out from the joint body 12 .

[0015] The limit sleeve 15 includes: an annular sleeve 151 and a strut 152 extending axially along the side wall of the annular sleeve 151. The front end of the strut 152 has a reinforcing block 153 extending radially, and the reinforcing block 153 is embedded in the metal In the gap 110 at the rear end of the electrode 11 .

[0016] In the tightening nut 14, the rear end of...

Abstract

The invention relates to a photovoltaic junction box connector. A limiting sleeve is supported between a metal electrode and a lock nut to prevent the metal electrode from being pulled out of a connector main body. The limiting sleeve comprises an annular sleeve and an upright axially stretching out of a side wall of the annular sleeve, wherein a reinforcing block radially stretching is arranged at the front end of the upright; and the reinforcing block is embedded into a notch at the rear end of the metal electrode. The limiting sleeve is mounted between the tail of the metal electrode of the connector and a cable sheath straining ring component, the upright pushes against the notch of the metal electrode, and the head of the annular sleeve pushes against the cable sheath straining ring component, so that a metal electrode terminal and the lock nut form overall support by the limiting sleeve of a cable in the connector. A drawing force of the cable for mounting the connector is above 400N.m, so that the drawing force is basically greater than a snap-in force of a cable core and the metal electrode terminal, and cable looseness and extraction caused by limiting can be permanently avoided.

Description

technical field [0001] The invention relates to the technical field of photovoltaic junction box connectors, in particular to a photovoltaic junction box connector with a limiting sleeve. Background technique [0002] Such as figure 1 , the existing cable joints for photovoltaic junction box connectors include: male and female connector nuts, anti-loosening jaws, T-shaped sealing rings, copper inserts, connecting plugs and connecting sockets, and the copper inserts include copper jacks, Copper plug and cable, the copper socket and the copper plug are crimped by stripping the wire end of the cable, and one end of the copper plug passes through the male and female connector nuts, anti-loosening jaws, T-shaped sealing rings and connecting sockets in sequence , the other end of the copper insert passes through the male and female connector nuts, anti-loosening jaws, T-shaped sealing rings and connecting plugs in sequence, and the connecting plugs and connecting sockets are conn...
