However, the spring piece is easily bent and deformed after multiple plugging and unplugging, resulting in reduced elasticity, so that the abutment between the spring piece and the terminal piece becomes loose, which easily leads to poor contact. Summary of the invention

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-2 This application is described in further detail.

[0035] The present application embodiment discloses a high voltage micro current micro connector, referring to Figure 1, including a body 1 that is rectangular as a whole, a socket 2 connected to the body 1 and a plug block 3 that is integrally arranged on the body 1, a slot 4 is opened at one end of the socket 2 in the width direction, the plug block 3 is inserted in the slot 4, electrode sheets 5 are embedded on both sides of the plug block 3 in the thickness direction, the electrode sheet 5 is arranged in contact with the plug block 3 on one side facing the plug block 3, and the electrode sheet 5 is flush with the plug block 3 on the side away from the plug block 3, one end of the electrode sheet 5 penetrates the socket 2 and extends into the body 1, and the electrode sheet 5 extends into the body 1 for connecting the line of the fresh air device, the body 1 is spliced ​​by two half blocks, the half block includes a half body 1 and a half plug block 3 that are injection molded, the electrode sheet 5 on the half block is placed in the mold when the half block is cast, and is synchronously fixed on the half block when the half block is cast, a conductive sheet 6 is installed in the slot 4 corresponding to the electrode sheet 5, the conductive sheet 6 is embedded on the inner wall of the slot 4, one side of the conductive sheet 6 abuts on the socket 2, and the other side of the conductive sheet 6 abuts on the socket 2 One side abuts against the electrode sheet 5, and the end of the conductive sheet 6 away from the slot 4 penetrates and extends out of the socket 2 away from the slot 4. The end of the conductive sheet 6 extending out of the socket 2 is used for welding wires, and the conductive sheet 6 is fixed in the socket 2; the electrode sheet 5 is embedded in the plug block 3, and the conductive sheet 6 is embedded in the slot 4. When plugging in, the electrode sheet 5 is supported by the plug block 3, and the conductive sheet 6 is supported by the slot 4, which reduces the probability of bending of the electrode sheet 5 after multiple plugging and unplugging; the fresh air system is widely used. When the fresh air system is used in a place with a small installation space such as a vehicle, the casting setting of the electrode sheet 5 and the body 1 is adopted, which not only facilitates the installation of the electrode sheet 5 on the body 1, but also the traditional installation steps such as grooving required when installing the electrode sheet 5 cause the body 1 to have sufficient thickness to ensure the grooving. Directly injecting the electrode sheet 5 onto the body 1 can reduce the thickness of the body 1, so that the volume of the connector can be smaller.

[0036] Reference Figure 1 , card slots 7 are opened at both ends of the insertion block 3 in the length direction, and elastic cards 8 are embedded in the corresponding card slots 7 in the slot 4, and the elastic card 8 is clamped in the card slot 7. Guide parts are integrally arranged at both ends of the elastic card 8 for inserting into the card slot 7 and escaping from the card slot 7. The guide parts are inclined. When subjected to force, the guide parts can drive the elastic card 8 to deform, thereby facilitating the elastic card 8 to insert into or escaping from the card slot 7. The force required to drive the elastic card 8 to insert into the guide part on one side of the card slot 7 is less than the force required to drive the elastic card 8 to escaping from the guide part on one side of the card slot 7. The force required for the elastic card 8 to escaping from the card slot 7 is greater than the force generated by random external force impact, so as to reduce the probability of the elastic card 8 escaping from the card slot 7 due to external force impact.

[0037] Reference Figure 1 and Figure 2The electrode sheet 5 includes a positive sheet 51 and a negative sheet 52. The positive sheet 51 and the negative sheet 52 are respectively arranged at the two ends of the length direction of the plug block 3. The positive sheet 51 is used to connect the conductive sheet 6 welded with the positive wire, and the negative sheet 52 is used to connect the conductive sheet 6 welded with the negative wire. A guide bar 9 is fixedly provided on the side of the plug block 3 away from the positive sheet 51, and a guide groove 10 is opened in the slot 4 corresponding to the guide bar 9. Since the guide bar 9 is divided into positive and negative poles, the fresh air system may not be used normally when the positive and negative poles are connected reversely. The guide bar 9 cooperates with the guide groove 10 to reduce the probability of reverse positive and negative connection; a confirmation groove 11 is opened at one end in the thickness direction of the socket 2. The opening of the confirmation groove 11 can identify the front and back sides of the socket 2 on the outside of the socket 2, thereby facilitating the insertion of the plug block 3 into the slot 4.

[0038] Reference Figure 1 and Figure 2 A bending piece 12 is provided at one end of the electrode sheet 5 extending into the body 1, and the bending piece 12 is integrally formed on the electrode sheet 5. The bending piece 12 can cooperate with the body 1 to clamp the wires of the fresh air system. The setting of the bending piece 12 can facilitate the positioning and installation of the wires of the fresh air system; a spot welding groove 13 is provided on the body 1 corresponding to the bending piece 12. The opening of the spot welding groove 13 can facilitate the demolding of the body 1 after injection molding. At the same time, when the curvature of the bending piece 12 cannot stably fix the wire, the spot welding groove 13 is used to spot weld the wire and the bending piece 12 to ensure the stability of the connection; a baffle 14 is embedded in the spot welding groove 13. The setting of the baffle 14 can cover the spot welding groove 13 after the wires of the fresh air system are welded to the electrode sheet 5, thereby protecting the bending piece and the welding points after welding.

[0039] Reference Figure 1 and Figure 2 An elastic protrusion 15 is fixedly provided on the end of the conductive sheet 6 facing the opening of the slot 4, and the elastic protrusion 15 abuts on the electrode sheet 5. The setting of the elastic protrusion 15 can improve the connection strength between the conductive sheet 6 and the electrode sheet 5; the plug block 3 includes an abutting portion 31 fixedly provided on the body 1 and an insertion portion 32 fixedly provided on the side of the abutting portion 31 away from the body 1. The slot 4 is a stepped groove, and the insertion portion 32 is inserted into the slot 4 to achieve fixation. The abutting portion 31 cooperates with the stepped groove to limit the amount of the insertion portion 32 inserted into the slot 4, thereby reducing the probability of the insertion portion 32 being inserted too deeply and causing damage to the socket 2.

[0040] Reference Figure 1 The electrode sheet 5 and the conductive sheet 6 are both formed by bending a plate, the plate is made of stainless steel, the outermost layer of the plate is gold-plated, and nickel is plated between the stainless steel layer and the gold-plated layer. The stainless steel layer is not easy to rust during use, and nickel plating can effectively enhance the electroplating strength of the gold-plated layer. Gold plating can effectively prevent the nickel-plated layer from chemically reacting during long-term use and affecting the use effect of the product.

[0041] The implementation principle of the embodiment of the present application is: two half blocks are spliced ​​together to form a body 1, during which the wires of the fresh air system are placed in the body 1, and then electric welding is performed in the electric welding groove, the electrode sheet is welded to the electrode sheet 5, and a baffle is embedded in the electric welding groove; then the plug block 3 is inserted into the slot 4, so that the electrode sheet 5 and the corresponding conductive sheet 6 are electrically connected to each other, and the installation and connection of the connector is completed.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
