Description

Technical Field

[0001] The present invention relates to the technical field of power connectors, and in particular to a power connector with a handle assist. Background Art

[0002] The power connector is a device used to achieve electrical connection of the power circuit. It consists of a male end and a female end, and the conductive connection is completed through a plug-in or locking structure. Its shell is mostly made of insulating materials (such as plastic, metal), and the internal terminals are generally copper alloy and nickel-plated or gold-plated to ensure conductivity and oxidation resistance. It has the characteristics of stable mechanical connection and reliable electrical contact. It can isolate the circuit when disconnected and transmit electrical energy when connected. It is widely used in electronic equipment, new energy vehicles, industrial machinery and other fields. There are various specifications according to different scenarios, such as USB interfaces suitable for low-voltage DC and industrial plugs suitable for high-voltage power. Some also have protection functions such as waterproof and anti-vibration. It is a key basic component in the power transmission system.

[0003] In the prior art, when using power connectors, it is often necessary to assemble the male end and the female end. During the assembly process, the user needs to use force to insert the male end into the female end or pull it out. This is not only labor-intensive, but when excessive force is used, it is very easy to cause wear of the male terminal or the female end, or cause the shell limiting structure to crack due to force impact, affecting the overall service life; if insufficient force is used, it may cause poor contact, affect the conductive stability, and cause problems with smooth assembly.

[0004] For this reason, we propose a power connector with handle power assistance. Summary of the Invention

[0005] (1) Technical problems solved

[0006] In response to the deficiencies of the prior art, the present invention provides a power connector with a handle assist, which solves the problem that the existing male and female ends need to be assembled by the user with force to insert or pull out the male end into or out of the female end, which not only does not save effort but also causes wear.

[0007] (2) Technical solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solutions: a power connector with handle assistance, comprising a male end body and a female end body, the male end body comprising a male end upper cover and a male end lower cover, a male end tail cover plate being installed on one side of the male end lower cover, and a male end vulcanization plug and a male end wire being installed on the surface, a male end positioning piece being installed in the male end lower cover, a male end sealing ring and a male end terminal being provided on the male end positioning piece, the female end body comprising a female end positioning piece, a female end vulcanization cap being installed on the surface of the female end positioning piece, and a female end terminal being provided in the female end positioning piece;

[0009] The cam is fixedly provided with a plurality of holes on the surface of the male end wrench, and the cam and the plurality of holes on the surface of the female end wrench are fixedly connected to each other and provide rotation support.

[0010] Preferably, the locking assembly includes a button body slidably connected to the inner wall of the male end wrench, the surface of the button body is fixedly connected to a locking mating male buckle, the surface of the male end tail cover is fixedly connected to a locking mating female buckle, and the button body is fixedly connected to a button spring on the side corresponding to the inner wall of the male end wrench. There are two button springs. Through the above components, when the male end wrench is reset, Figure 1 As shown, the button body and the locking mating male buckle can be driven to move. When they move to a certain position, the locking mating female buckle squeezes the locking mating male buckle, thereby driving the button body to move. The button spring is subjected to force. When the male end wrench is reset, the locking mating female buckle loses its squeeze on the locking mating male buckle. The button spring drives the button body and the locking mating male buckle to reset, and counteracts the locking mating female buckle to realize the locking operation and improve the overall stability.

[0011] Preferably, the surface of the male end wrench is fixedly connected to a limiting female buckle, and the surface of the button body is fixedly connected to a limiting male buckle. Through the above components, when the button body is moving, the limiting male buckle cooperates with the limiting female buckle to perform a limiting operation on the button body.

[0012] Preferably, the positioning portion includes two protrusions fixed on the surface of the male end wrench, and the two sides of the male end lower cover are respectively fixedly connected to the limit blocks. Through the above components, when the male end wrench is rotated to 90 degrees, the male end wrench drives the protrusions to move and contact with the limit blocks to achieve positioning, limiting the movement of the wrench within a 90-degree range.

[0013] Preferably, the positioning part also includes an auxiliary seat fixed on the surface of the male end wrench, and the inner wall of the auxiliary seat is slidably connected to a positioning piece, and the positioning piece is fixedly connected to the side corresponding to the inner wall of the auxiliary seat with a reset spring, and positioning grooves are provided on both sides of the male end upper cover, and the positioning piece is plugged into the limit groove. Through the above components, when the male end wrench is rotated to 90 degrees, the male end wrench drives the positioning piece to move to the positioning groove, and the reset spring drives the positioning piece to be inserted into the positioning groove, ensuring that the male end wrench is stably at 90 degrees, which facilitates the stable insertion of the rear directional column into the guide rail groove. When the male end wrench is reset, only the male end wrench needs to be pushed, the positioning groove squeezes the positioning piece, and the positioning piece moves in the auxiliary seat, which is convenient for quickly releasing the restriction.

[0014] Preferably, the positioning member includes a latch, and a ball is provided on the inner wall of the latch.

[0015] Preferably, the rotating shaft is composed of a shaft and a protrusion fixed on the surface of the shaft.

[0019] In summary, the technical effects and advantages of the present invention are as follows:

[0020] 1. In the present invention, a resistance mechanism is provided and the male end wrench is rotated. The guide groove in the male end wrench cooperates with the directional column to convert the axial force of the traditional straight insertion into the tangential force of the wrench rotation, so that the operator only needs to apply a small rotational force to complete the docking of the male end and the female end, which is also convenient for subsequent labor-saving extraction. The positioning column cooperates with the guide groove to guide the male end to be inserted along a fixed track, so that the male end body and the female end body can be accurately docked, reducing wear during the assembly process and improving the smoothness of the overall assembly.

[0021] 2. In the present invention, by setting a positioning part, when the male end wrench is rotated, the protrusion cooperates with the limit block to limit the rotation of the male end wrench within a range of 90 degrees. When the male end wrench is rotated to 90 degrees, the reset spring can drive the positioning part composed of the pin and the ball to move and insert it into the positioning groove, ensuring that the male end wrench is stable at 90 degrees, which facilitates the stable connection between the rear directional column and the guide rail groove.

[0022] 3. In the present invention, by setting a locking assembly, when the wrench is reset, the button body, button spring, locking male buckle and locking female buckle cooperate to lock the male end wrench, ensuring the stability of the male end wrench, and at the same time reducing the loosening of the male end and the female end under working conditions such as vibration and impact, thereby improving the overall stability effect.
