Description

Technical Field

[0001] The utility model belongs to the technical field of electrical connectors, and particularly relates to a connector structure. Background Art

[0002] Electrical connectors are commonly used components in the electronics industry, usually used for power connection or signal transmission. For example, the connection end of a commonly used power adapter usually uses a standard connector to plug into an electrical device. The connector of the power adapter generally includes a conductive sleeve, a conductive pin, and a plastic head. The conductive pin is located in the conductive sleeve and is connected and insulated through the plastic head.

[0003] For example, the Chinese patent document with the publication number CN219180910U discloses a transfer charging connector applicable to different voltage platforms, including a vehicle body 36V charging female socket, a adapter, and a charging end 48V male plug. The front end of the adapter is matched with the female socket of the vehicle body 36V charging female socket, and the rear end of the adapter is matched with the male socket of the charging end 48V male plug. The front terminal includes a front insulating column, a front outer conductive column, a front inner conductive column, a front insulator, and a front center pin. The front outer conductive column is sleeved outside the front insulating column, a limiting step is provided behind the front insulating column, the front outer conductive column abuts against the limiting step, the front inner conductive column is sleeved inside the front insulating column, the front ends of the front insulating column, the front outer conductive column, and the front inner conductive column extend out from the front of the housing, the front insulator is sleeved inside the front inner conductive column, the front center pin is installed at the center of the front insulator, and the front center pin is spaced apart from the inner walls of the front insulating column and the front inner conductive column to form a first chamber.

[0004] In the technical solution disclosed in the above patent document, the center pin is a copper column structure, and the front inner conductive column is a sleeve structure.

Using copper bar turning for molding has high material costs and also increases the processing procedures, resulting in high overall costs. Summary of the Utility Model

[0030] In an embodiment of the connector structure of the present utility model, please refer to Figures 1 to 4; The connector structure of this embodiment includes a conductive sleeve 100, a conductive plug 200, and a plastic connector 300. The plastic connector 300 includes a body 310. A blind hole is provided in the body 310, and a support column 320 extends in the blind hole. An annular hole (not shown in the drawing) is formed between the support column 320 and the inner wall of the blind hole. The support column 320 is provided with a mounting hole (not shown in the drawing). The conductive plug 200 is disposed in the mounting hole, with one end extending out of the mounting hole and the other end provided with a first connector 210. The first connector 210 passes through the body 310. The conductive sleeve 100 is disposed in the annular hole, with one end extending out of the annular hole and the other end provided with a second connector 110. The second connector 110 passes through the body 310. Specifically, the conductive plug 200 includes a first sheet metal 201, and the insertion end of the conductive plug 200 is formed by curling the first sheet metal 201. And the first connector 110 is disposed at one end of the first sheet metal 201. The conductive sleeve 100 is formed by curling a second sheet metal 101, and the second connector 110 is connected to one end of the second sheet metal 101. More specifically, the plastic connector 300 is injection-molded in the mold between the conductive sleeve 100 and the conductive plug 200, and connects the conductive sleeve 100 and the conductive plug 200 into one body. Among them, the first connector 210 and the second connector 110 are used to connect the positive and negative poles of the power line or the neutral line and the live line respectively.

[0031] For the connector of this embodiment, the conductive plug 200 and the conductive sleeve 100 are formed by bending and curling sheet metal, which replaces the existing method of turning copper rods. This not only saves material costs, but also has a higher efficiency and lower production cost in the bending and curling forming method compared to the turning forming method.

[0032] Further, referring to Figure 3 , the first connector 210 and the second connector 110 are arranged in a vertically offset manner. This avoids the problem of interference between the first connector 210 at the end of the conductive plug 200 and the second connector 110 at the end of the conductive sleeve 100.

[0033] Further, referring to Figures 4 to 8 , the conductive sleeve 100 and the conductive plug 200 are formed by stamping a strip of material, and the first connector 210 and the second connector 110 are connected to the same strip of material; the conductive plug 200 is located inside the conductive sleeve 100. In this embodiment, the conductive plug 200 and the conductive sleeve 100 can be formed on the same strip of material, so that the forming of the conductive sleeve 100 and the conductive plug 200 can be continuously completed by one strip of material, and continuous stamping forming can be achieved. In addition, when the plastic connector 300 is injection-molded between the conductive plug 200 and the conductive sleeve 100, positioning can be carried out through the strip of material, so that the conductive plug 200 and the conductive sleeve 100 are positioned in the injection mold.

[0034] Further, please refer to Figures 4 to 7, a free end of the first sheet metal 201 is provided with a plurality of slits, and two adjacent slits form a bent portion; after the first sheet metal 201 is curled, each bent portion is bent inward to form a closed ball head structure 202. The ball head structure 202 forms a guiding structure of the conductive plug 200.

[0035] Further, referring to Figure 1 , two first crimping portions 211 extend from two sides of the first connector 210, and the two first crimping portions 211 form a first crimping groove 212. Second crimping portions 111 are provided on two sides of the second connector 110, and the two second crimping portions 111 form a second crimping groove 112. In this embodiment, wires respectively connecting the conductive plug 200 and the conductive sleeve 100 can be respectively placed in the first crimping groove 212 and the second crimping groove 112, and the wires are tightly pressed and fixed by riveting the first crimping portion 211 and the second crimping portion 111.

[0036] Furthermore, concave cavities are inwardly recessed on the outer sides of the first crimping portion 211 and the second crimping portion 111, and the concave cavities form bosses. Therefore, when the first crimping portion 211 and the second crimping portion 111 tightly press the corresponding wires, the firmness of connection with the wires can be increased, and the connection stability can be increased.

[0037] Further, please refer to Figure 9 , one end of the conductive plug 200 connected to the first connector 210 is further provided with a plug 205, and the plug 205 seals the port of the conductive plug 200. In this embodiment, by sealing the port of the conductive plug 200 with the plug 205, when the conductive plug 200 is electroplated, it can effectively prevent the electrolyte from entering the inside of the conductive plug 200. And by supporting the port of the conductive plug 200 with the plug 205, the problem of deformation of the mouth portion of the conductive plug 200 can be further avoided.

[0038] Furthermore, a convex portion 206 is inwardly recessed on the outer side of the conductive plug 200, and the convex portion 206 limits the plug 205. Therefore, the plug 205 can be limited by the convex portion 206 to prevent the plug 205 from bending into the inside of the conductive plug 200. The convex portion 206 can be formed on the first sheet metal 201 by stamping.

[0039] The connector of the above embodiment can be formed by steps such as stamping and bending a copper strip. Specifically, please refer to Figures 4 to 8, The copper strip can complete the stamping and forming of the connector through the following steps. Specifically: Stamp and form the first sheet metal 201 and the second sheet metal 101 on a copper strip 10. A first connecting piece 210 is formed between the end of the first sheet metal 201 and the copper strip 10, and a second connecting piece 110 is formed between the end of the second sheet metal 202 and the copper strip 10. Gradually bend and curl the first sheet metal 201 to form a columnar conductive plug 200. Then bend the first connecting piece 210 and / or the second connecting piece 110 so that the conductive plug 200 is vertically offset from the second sheet metal 101. Therefore, the second sheet metal 101 can be gradually bent and curled to form a conductive sleeve 100, and the conductive sleeve 100 wraps the conductive plug 200 so that the conductive plug 200 is located at the center of the conductive sleeve 100. Finally, in-mold injection molding is carried out. The conductive sleeve 100 and the conductive plug 200 are positioned in the injection mold, and then injection molding is carried out to form a plastic connecting piece 300 connecting the conductive sleeve 100 and the conductive plug 200. In the above forming method, the conductive plug 200 and the conductive sleeve 100 are stamped and formed by the copper strip 10, which can achieve continuous stamping processing, improve efficiency, and reduce material costs. Moreover, after the conductive sleeve 100 and the conductive plug 200 are formed, they are still connected to the copper strip 10. When injection molding the plastic connecting piece, the conductive plug 20 and the conductive sleeve 100 can be positioned in the injection mold by using the positioning of the copper strip 10, and then injection molding can be completed.

[0040] Furthermore, please refer to Figure 5 and Figure 6 , In order to form a ball head structure 202 at the end of the conductive plug 200, it is necessary to punch out a plurality of V-shaped grooves 203 at the free end of the first sheet metal 201. Through the V-shaped grooves 203, a plurality of sealing edges 204 are formed at the end of the first sheet metal 201. Therefore, while the first sheet metal 201 is being curled, the sealing edges 204 are bent inward so that the sealing edges 204 are spliced to form the ball head structure 202. The ball head structure 202 can seal the end of the conductive plug 200, and under the interaction of the closed parts 204, the strength of the end of the conductive plug 200 can be increased to avoid deformation. And it can also play the role of plugging and guiding.

[0041] Furthermore, please refer to Figures 5 to 7 and Figure 9 , In order to provide a plug 205 at the other end of the conductive plug 200, a plug 205 can be stamped and formed at the end of the first sheet metal 202 close to the first connecting piece 210, and the punched and formed plug 205 is perpendicular to the first sheet metal 201. When the first sheet metal 201 is rolled into a cylindrical structure, the plug 205 just seals the mouth of the conductive plug 200.

[0042] Specifically, please refer to Figure 7, when the conductive plug 200 is formed after the first sheet metal 201 is rolled, the plug 205 seals the port of the conductive plug 200. In this embodiment, by sealing the port of the conductive plug 200 with the plug 205, electroplating can be carried out on the conductive plug 200, which can effectively prevent the electrolyte from entering the inside of the conductive plug 200. And by supporting the port of the conductive plug 200 with the plug 205, the problem of deformation of the mouth of the conductive plug 200 can be further avoided.

[0043] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
