There is negative pole screw thread, on the positive pole screw thread with the negative pole screw thread, be provided with the back-off of projection, also include and the positive pole
Screw thread is engaged and locking nut with the negative pole screw thread, is additionally provided with locking nut edge internal thread non-return recessed
Button, the non-return recessed button coordinates with the back-off.
Further, the back-off includes straight flange, and the straight flange is arranged on the positive pole screw thread or the negative pole threading path
To on the extended line of diameter.
Further, one or more back-offs are provided with the positive pole screw thread and the negative pole screw thread.
Further, 2 back-offs are provided with the positive pole screw thread and the negative pole screw thread, 2 back-offs set
Put at radial diameter two ends.
Further, the non-return recessed button is the multiple of continuous setting, is uniformly arranged on the inner periphery of the locking nut
On.
Further, the positive pole screw thread and the negative pole screw thread away from the contact pin and the sleeve one end,
It is additionally provided with card cover.
Further, the positive pole screw thread and the negative pole screw thread away from the contact pin and the sleeve one end,
It is additionally provided with sealing ring.
The beneficial effects of the utility model are：
Photovoltaic connector forced locking device disclosed in the utility model, structure design advantages of simple passes through
The raised back-off of positive pole screw thread and negative pole screw tip is arranged on, the recessed button with anti-stopping function is set in nut screw thread mouth,
After nut is locked, cam and recessed button are engaged, and play auto lock effect, and instead of the locking of convention connectors nut needs gluing
Technique, make connector assembly technology simplify, mechanical performance is optimized, while more having saved cost of labor.

Specific embodiment
The utility model specific embodiment is described in detail with reference to specific embodiment.
As shown in figure 1, a kind of photovoltaic connector forced locking device, including positive pole 1 and negative pole 2, the positive pole 1
Sleeve 4 and wire 11 are internally provided with, outside is provided with positive pole screw thread 5, in the negative pole 2 contact pin 3 and wire are internally provided with
11, negative pole screw thread 6 is provided with outside the negative pole 2, in the positive pole screw thread 5 with the negative pole screw thread 6 away from both positive and negative polarity
The end of junction, is additionally provided with card cover 9 and sealing gasket 10, on the positive pole screw thread 5 with the negative pole screw thread 6, is respectively provided with
Have the back-off 7 of projection, also include being engaged with the negative pole screw thread 6 with the positive pole screw thread 5 and locking nut 12, described
Non-return recessed button 8 is additionally provided with the edge internal thread of locking nut 12, the non-return recessed button 8 coordinates with the back-off 7.
As Figure 2-3, the back-off 7 includes straight flange 71, and the straight flange 71 is arranged on the positive pole screw thread or described negative
On the extended line of pole screw thread radial diameter.As shown in figure 4, the back-off 7 is raised triangle, in the present embodiment, in institute
State and 2 back-offs 7 are provided with positive pole screw thread 5 and the negative pole screw thread 6,2 back-offs 7 are arranged on radial diameter two ends.
As illustrated in figures 4-5, the non-return recessed button 8 is the multiple of continuous setting, is uniformly arranged on the locking nut 12
On inner periphery.Minor face 81 is again provided with non-return recessed button 8, minor face 81 and straight flange 71 cooperate locking.It is non-return it is recessed button 8 with
Back-off 7 coordinates, it is ensured that locking nut 12 is merely able to just want to be screwed on positive pole screw thread 5 or negative pole screw thread 6, but due to non-return recessed button
After being combined with back-off, because the locking of the two is acted on, locking nut 12 is set to revolve from positive pole screw thread 5 or negative pole screw thread 6 again
Screw down, it is ensured that locking nut 12 and positive pole 1 or the connective stability of negative pole 2.
