The specific embodiment is as follows:
the invention will be further described with reference to specific examples and figures.
Referring to fig. 3 to 6, the present invention is a conductive connector for a charging gun, the conductive connector comprising: plastic seat 1, sleeve 2 and contact 3.
The contact 3 is formed by stamping a metal plate, and then is coiled into a set shape by a forming machine. As shown in fig. 5 and 6, the contact 3 is integrally formed with: a plurality of contact arms 31, a connecting portion 32 and a wiring portion 33. The number of contact arms 31 is set according to practical needs, and is generally 4-8.
The contact 3 is wound in a cylindrical shape, that is, the connecting portion 32 is cylindrical, the plurality of contact arms 31 extend forward from the connecting portion 32 and are surrounded in a cylindrical shape, and the front clamping protrusion 321 and the rear clamping protrusion 322 with opposite protruding directions are integrally formed along the circumferential surface of the connecting portion 32.
The contact arms 31 extend forward from the connecting portion 32, and the front ends 310 of the contact arms 31 are turned outwards, so that the front ends 310 of all the contact arms 31 are enclosed to form a bell mouth shape, and are bent inwards to form a bending protrusion 311 near the front ends 310 of the contact arms 31.
The connection part 33 is formed in a cylindrical shape by extending the connection part 32 backward, and a notch 331 is formed at the combining position of the connection part 33 and the connection part 32. The wire ends of the power wires are clamped and fixed through the wiring parts 33, so that the wires in the power wires are in conductive connection with the contact 3.
The plastic seat 1 is integrally formed and fixedly connected to the connecting part 32, and the wiring part 33 extends out from the rear end of the plastic seat 1. In order to make the connection between the plastic seat 1 and the contact element 3 more stable, an injection hole 323 is formed on the connecting portion 32 of the contact element 3. When the plastic seat 1 is integrally formed on the contact piece 3, raw materials enter the inner cavity of the connecting part 32 through the injection molding hole 323 when the plastic seat 1 is formed, so that the plastic seat 1 and the contact piece 3 form stable connection, and the situation that the plastic seat 1 and the contact piece are loose or even separated in the use process is prevented. The notch 331 formed at the combining position of the connection portion 33 and the connection portion 32 also has the same effect.
The plastic seat 1 is used for fixing the charging gun, so that the plastic seat 1 can also be directly replaced by a plastic part of a plug part in the charging gun, namely, the contact piece 3 can be integrally formed in the plastic part in the charging gun plug, and the plastic seat can also play a role in fixing the contact piece 3.
In addition, an air hole 320 is formed on the connecting portion 32, and the air hole 320 is located behind one of the front locking protrusions 321. The air holes 320 function as: due to the presence of the air holes 320, the fluidity of the plating solution is enhanced when the contact 3 is plated. Meanwhile, when the conductive pin (post) is inserted into the contact 3 in use, the air hole 320 can smoothly discharge the air in the contact 3 due to the existence of the air hole, thereby facilitating the insertion of the conductive pin.
The sleeve 2 is sleeved outside the cylindrical structure surrounded by the contact arms 31, a hole groove 20 is formed in the sleeve 2 corresponding to each contact arm 31, and the sleeve 2 is connected with the contact element 3 by a buckle, namely, a clamping groove 21 and a clamping hole 22 are formed in the sleeve 2 corresponding to the front clamping convex 321 and the rear clamping convex 322.
The shape of the hole groove 20 on the sleeve 2 is larger than the projection of the contact arm 31, so that the contact arm 31 can be stretched and deformed into the hole groove 20 when being pressed internally.
In addition, a plurality of guiding convex points 23 are uniformly formed on the inner edge of the sleeve 2 near the front end port. The guiding projection 23 functions as: when the conductive pin is inserted into the sleeve 2, the conductive pin can be prevented from interfering with the end of the contact arm 31, and the conductive pin is positioned at the central position of the sleeve 2 through the support of the guide boss 23, so that the conductive pin can be conveniently and smoothly inserted into the central position of the contact arm 31 surrounding the cylindrical structure.
In order to facilitate the plug-in fit of the sleeve 2 with the contact 3, the rear end port 24 of the sleeve 2 is flared, i.e. the edge of the rear end port 24 is slightly rolled outwards.
When the sleeve 2 and the contact 3 are assembled, the front end of the contact arm 31 of the contact 3 is directly inserted from the rear end port 24 of the sleeve 2, and the clamping groove 21 and the clamping hole 22 of the sleeve 2 are correspondingly positioned with the front clamping convex 321 and the rear clamping convex 322 on the contact 3. After the front clamping convex 321 is inserted into the specified depth, the front clamping convex 321 is inserted along the clamping groove 21 and finally forms interference with the clamping groove 21, so that the sleeve 2 cannot go deep. At the same time, the rear locking protrusion 322 just falls into the locking hole 22, and the sleeve 2 cannot be pulled out.
In operation of the invention, a plurality of conductive pins (posts) are provided in the facility socket to be charged, and when a charging gun using the invention is inserted into the socket, the conductive pins will be correspondingly inserted into the invention. Firstly, the conductive pin will extend into the middle of the cylindrical structure enclosed by the contact arm 31 through the guiding of the guiding convex portion 23, the side surface of the conductive pin will interfere with the bending convex portion 311 on the contact arm 31, and as the conductive pin extends into, it will apply an outward force to the contact arm 31 through the bending convex portion 311, the contact arm 31 will bend outwards under this pressure, and a space for bending deformation of the contact arm 31 is given to the contact arm 31 through the hole groove 20 formed on the sleeve 2. Due to the bending deformation of the contact arm 31, the bending protrusion 311 of the contact arm 31 is tightly abutted against the surface of the inserted conductive pin under the action of the self elastic deformation force, thereby forming a tight conductive contact.
According to the invention, the metal sleeve 2 and the contact 3 can be directly formed by stamping, so that the production cost of the invention can be greatly reduced compared with the existing production mode, and meanwhile, the automatic operation can be realized, the production efficiency can be greatly improved, and the invention has the advantages of low cost, good conductivity stability, convenience in production and processing and the like compared with the existing product.
In order to improve the waterproof effect of the invention, a waterproof structure can be added on the invention, as shown in fig. 7, and a waterproof ring 4 is added on the plastic seat 1. The concrete structure is as follows: a step section 11 is formed on one side of the plastic seat 1, which is close to the sleeve 2, and a waterproof ring 4 is sleeved on the step section 11. After the waterproof ring 4 is added, the plug area, the wire connection area and the circuit control area inside the charging gun form a closed waterproof design after the charging gun is assembled, and liquid such as external water is prevented from entering the charging gun through the conductive connecting piece.
It is understood that the foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, but rather is to be accorded the full scope of all such modifications and equivalent structures, features and principles as set forth herein.
