Background technique

With the development of society, the demand for energy is getting higher and higher, and the energy crisis is intensifying. The development of new energy has become a topic that people attach importance to. Among various emerging energy sources, solar technology is relatively mature and applied to home appliances, solar power generation, and even building solar buildings, which are used by the public.

Currently, in these solar devices, the power connection socket is widely used as a carrier for extending cable connections. Most of these devices need to be exposed to the outdoors and experience wind and rain. The design of the sealing ring in the seat body is not tight enough, so that water and dust have the opportunity to enter the connection seat, causing a short circuit; the contact resistance of the metal terminals is not tight enough, so that the contact resistance cannot meet the requirements. It affects the use of the equipment; the connection design of the male-female connection seat is improper, which makes it difficult to remove and plug the seat body, which is not conducive to the connection and fixation of the two; in addition, too much glue is used for the shape, resulting in high production costs.

In order to achieve the above purpose, the technical solution adopted by the utility model is: in the connection seat, the contraction claw, the sealing ring, the metal terminal and the closing nut are sequentially connected, and the connection seat and the metal terminal are divided into male and female. The male seat of the seat is plugged into the slot of the connecting end of the female seat with the claw of the connecting end, and the male terminal of the metal terminal is fixedly inserted in the female seat. There is a raised structure in the middle of the connecting end of the male terminal, and the female terminal is fixed. Connected to the connecting end of the male seat, there is a recessed structure in the middle of the connecting end of the female terminal, the sealing ring is inserted into the sealing groove of the connecting seat, one end of the sealing ring has a boss, and the shrinking claw is sleeved on the sealing On the boss of the ring, the closed nut is threadedly connected to the closed end of the connecting seat.

There is a circular arc card edge on the card slot of the female seat, and an extended clamp arm is provided at the end corresponding to the card slot.

There is a male seat connecting groove inside the connecting end of the female seat, and an auxiliary slot recessed toward the inner wall of the female seat is provided on one side of the male seat connecting groove.

The corresponding end of the claw of the male seat has a trapezoidal surface, and the trapezoidal surface is closely matched with the extended clamp arm of the female seat. There is a ring groove at the bottom of the connecting end of the male seat, and a waterproof ring is sleeved on the ring groove. The connecting end There is a raised rib on the plane on one side, and the raised rib is consistent with the position of the auxiliary slot in the female seat.

There is a connection hole at the terminal of the male seat and the female seat, and the cross section of the connection hole is T-shaped.

The terminal of the metal terminal is an arc clasp, the convex structure of the male terminal is in the shape of a strip-shaped circular shaft, and the connection end of the female terminal is in the shape of a strip-shaped circular tube.

There are through holes in the center of the shrinking claw and the closing nut, and the two are coaxially matched with the connecting seat and the sealing ring to be closely connected, and the edge of the sealing ring is chamfered.

The beneficial effect of the utility model is that: the design of the claws and slots of the male and female seats, together with the convex ribs on the male seat and the auxiliary slots on the connecting groove of the male seat in the female seat, cooperate with the trapezoidal surface on the outer surface of the male seat and The extension clamp arm of the female seat cooperates to make the connection between the two more stable and easy to pull out. The step and chamfer design of the sealing ring cooperate with the shrinking claw and the closing nut to apply pressure. Through the anti-tension effect of the sealing ring, it can achieve Secondary waterproofing, to avoid the occurrence of short circuit, the waterproof ring at the bottom of the connection end of the male seat makes the connection between the male and female seats more tightly, waterproof and dustproof. The excellent electrical connection of the terminal, and the simple appearance thereof greatly reduce the material used for the connection seat and save the production cost.
