Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a cold-pressed terminal and an electrical combined connector. Background Art

[0002] Currently in the domestic market, cold-pressed terminals are a common electrical connection accessory. The most effective way to use them is to maintain sufficient contact pressure to ensure the stability and reliability of circuit connections.

[0003] In actual use, in order to apply sufficiently large contact pressure to the cold-pressed terminal, it is often used in combination with an electrical combination connector.

[0004] However, during the installation of electrical combination connectors in the wiring harness, due to the limited operating space, it is easy for the electrical combination connectors to slip off the cold-pressed terminals when installed by a single person, and it is difficult to locate the installation position of the electrical combination connectors, resulting in installation position deviation and poor electrical contact. Utility Model Content

[0005] Aiming at the defects of the existing electrical combined connector in the prior art, such as being difficult to position and easy to slip, the utility model provides a cold-pressed terminal and an electrical combined connector, which can solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the utility model provides a cold-pressed terminal, which includes a gasket portion and a wiring portion that are integrally arranged, the gasket portion is used to cooperate with the connector, and the wiring portion is used to cooperate with the wire;

[0007] A puncture portion is formed on one side of the gasket portion, and the puncture portion is used to cooperate with the electrical contact.

[0008] Among them, the puncture part can easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact and cooperate closely with the electrical contact. There is no need to perform oxide layer polishing, paint protection, electroplating protection and other operations on the electrical connection points, which reduces the process processing requirements for electrical parts.

[0009] Preferably, the gasket portion is provided with a connecting hole for the connecting member to pass through in a direction from the one side to the other side.

[0010] Among them, when the connecting hole is matched with the connecting piece, it is effectively ensured that the connecting piece will not be offset relative to the cold-pressed terminal, thereby reducing the possibility of installation position deviation of the electrical connecting piece.

[0011] Preferably, the gasket portion extends toward the inner periphery of the connecting hole to form an interference ring portion for interfering with the connecting piece, and a central area of ​​the interference ring portion forms a matching hole for matching with the connecting piece;

[0012] The connector is a threaded connector, and the interference ring portion is used to interfere with the threaded area of ​​the threaded connector; wherein the inner diameter of the interference ring portion is not greater than the major diameter of the threaded area and not less than the minor diameter of the threaded area.

[0013] Among them, when the interference ring interferes with the threaded area of ​​the threaded connector, the threaded connector no longer easily detaches from the cold-pressed terminal, reducing the risk of the threaded connector slipping during the installation of the electrical connector, thereby reducing the difficulty of installing the electrical connector.

[0014] Preferably, the puncture portion is connected to the gasket portion in one piece or in separate pieces.

[0015] In combination with actual usage, the puncture portion can be obtained by protruding from a part of the structure of the gasket portion; or the protruding structure can be obtained from the outside and installed on the gasket portion.

[0016] Preferably, the puncture portion is integrally connected to the gasket portion, and the puncture portion is a raised structure protruding from one side of the gasket portion.

[0017] In an actual production process, a protruding structure protruding from the other side of the gasket portion toward the one side of the gasket portion can be formed by a process such as stamping.

[0018] Preferably, the puncture portion is integrally connected to the gasket portion, and the puncture portion includes a puncture piece structure obtained by punching out the gasket portion; the puncture piece structure is partially connected to the gasket portion, and the puncture piece structure is bent toward the one side of the gasket portion to form the puncture portion.

[0019] Before the cold-pressed terminal is punched, its overall structure is located on a plate with thickness, and is punched according to the solid lines on the plate. In order to obtain the puncture piece structure by punching from the gasket part, it has a first punching line and a second punching line, and then the obtained puncture piece structure is bent according to the first bending line to form a puncture part.

[0020] Preferably, the puncture portion is formed at a central area of ​​the gasket portion.

[0021] Among them, during the connection process of the electrical connector, when the puncture portion is formed in the central area of ​​the gasket portion, it can obtain greater contact pressure and thus more easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact to cooperate with the electrical contact; if the puncture portion is formed in the edge area of ​​the gasket portion, it not only increases the difficulty of penetration of the puncture portion, but also easily causes the gasket portion of the cold-pressed terminal to bend.

[0022] Preferably, a wire threading hole is formed at the wiring portion, and the wire threading hole is used to cooperate with the wire; the wiring portion is formed by bending a wiring piece integrally formed at the gasket portion, and the wiring piece is formed by punching.

[0023] Take a plate with thickness, punch it out according to the implementation on the plate, and then bend it according to the second bending line and the third bending line to obtain a wiring piece formed integrally at the gasket part, and finally connect the side of the wiring piece away from the bending line to obtain a wire threading hole for cooperating with the wire.

[0024] The utility model also provides an electrical combined connector, which comprises a connector and a cold-pressed terminal for matching with the connector; the cold-pressed terminal adopts the cold-pressed terminal mentioned above.

[0025] Preferably, the connecting piece is a threaded connecting piece.

[0026] The utility model adopts a threaded connector to cooperate with the interference ring portion at the cold-pressed terminal gasket portion, which reduces the risk of the electrical combination connector slipping during installation. At the same time, a puncture portion is formed on one side of the gasket portion. The protruding characteristics of the puncture portion can easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact and cooperate closely with the electrical contact, effectively solving the problem of poor electrical contact.

[0032] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0033] Example 1

[0034] like Figure 1-5 As shown, this embodiment provides a cold-pressed terminal 200 .

[0035] Seen in Figure 2 In this embodiment, a cold-pressed terminal 200 includes a gasket portion 210 and a wiring portion 220 that are integrally provided. The gasket portion 210 is used to cooperate with the connector 100, and the wiring portion 220 is used to cooperate with the wire.

[0036] A puncture portion 214 is formed on one side of the gasket portion 210 , and the puncture portion 214 is used to cooperate with an electrical contact.

[0037] Among them, the puncture part 214 can easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact and fit closely with the electrical contact. There is no need to perform oxide layer polishing, paint protection, electroplating protection and other operations on the electrical connection points, which reduces the process processing requirements for electrical components.

[0038] Seen in Figure 2 The gasket portion 210 is provided with a connecting hole for the connecting member 100 to pass through in the direction from the one side to the other side.

[0039] Among them, when the connecting hole is matched with the connecting piece, it is effectively ensured that the connecting piece will not be offset relative to the cold-pressed terminal, thereby reducing the possibility of installation position deviation of the electrical connecting piece.

[0040] In a cold-pressed terminal 200 of this embodiment, the gasket portion 210 extends toward the inner periphery of the connection hole to form an interference ring portion for interfering with the connector, and a central area of ​​the interference ring portion forms a mating hole 215 for mating with the connector 100;

[0041] The connector 100 is a threaded connector, and the interference ring portion is used to interfere with the threaded area 110 of the threaded connector; wherein the inner diameter of the interference ring portion is not greater than the major diameter of the threaded area 110 and not less than the minor diameter of the threaded area.

[0042] Among them, when the interference ring interferes with the threaded area 110 of the threaded connector, the threaded connector no longer easily detaches from the cold-pressed terminal, reducing the risk of the threaded connector slipping during the installation of the electrical connector, thereby reducing the difficulty of installing the electrical connector.

[0043] Seen in Figure 3 In a cold-pressed terminal 200 of this embodiment, the puncture portion 214 is connected to the gasket portion 210 in one piece or in separate pieces.

[0044] In combination with actual usage, the puncture portion 214 can be protruded from a part of the structure of the gasket portion 210; or a protruding structure can be obtained from the outside and installed on the gasket portion 210.

[0045] Seen in Figure 4 In a cold-pressed terminal 200 of this embodiment, the puncture portion 214 is integrally connected to the gasket portion 210 , and the puncture portion 214 is a protruding structure protruding from one side of the gasket portion 210 .

[0046] In an actual production process, a protruding structure protruding from the other side of the gasket portion 210 toward the one side of the gasket portion can be formed by a process such as stamping.

[0047] In a cold-pressed terminal 200 of this embodiment, the puncture portion 214 is integrally connected to the gasket portion 210, and the puncture portion 214 includes a puncture piece structure obtained by punching out the gasket portion 210; the puncture piece structure is partially connected to the gasket portion 210, and the puncture piece structure is bent toward the side of the gasket portion 210 to form the puncture portion 214.

[0048] Combine Figure 2 For example, before the cold-pressed terminal 200 is punched, its overall structure is located on a plate 300 with a thickness, and is punched according to the solid lines on the plate 300. In order to obtain the puncture piece structure by punching from the gasket part, it has a first punching line 211 and a second punching line 212, and then the obtained puncture piece structure is bent according to the first bending line 213 to form a puncture part 214.

[0049] Seen in Figure 3 In a cold press terminal 200 of this embodiment, the puncture portion 214 is formed at the central area of ​​the gasket portion 210 .

[0050] Among them, during the connection process of the electrical connector, when the puncture portion 214 is formed in the central area of ​​the gasket portion 210, it can obtain greater contact pressure and thus more easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact to cooperate with the electrical contact; if the puncture portion 214 is formed in the edge area of ​​the gasket portion 210, it not only increases the difficulty of penetration of the puncture portion 214, but also easily causes the gasket portion 210 of the cold press terminal 200 to bend.

[0051] Seen in Figure 5 In a cold-pressed terminal 200 of this embodiment, a wire hole 223 is formed at the wiring portion 220, and the wire hole 223 is used to cooperate with the wire; the wiring portion 220 is formed by bending a wiring piece integrally formed at the gasket portion 210, and the wiring piece is formed by punching.

[0052] Combine Figure 2 For example, a plate 300 having a thickness is taken, punched out according to the implementation on the plate 300, and then bent according to the second bending line 221 and the third bending line 222 to obtain a wiring piece integrally formed at the gasket 210, and finally connected to the side of the wiring piece away from the bending line to obtain a threading hole 223 for cooperating with the wire.

[0053] This embodiment further provides an electrical assembly connector, which includes a connector 100 and a cold-pressed terminal 200 for cooperating with the connector; the cold-pressed terminal 200 adopts the cold-pressed terminal 200 described above.

[0054] Seen in Figure 1 , the connecting piece 100 is a threaded connecting piece.

[0055] This embodiment uses a threaded connector to cooperate with the interference ring portion at the gasket portion 210 of the cold-pressed terminal 200, thereby reducing the risk of the electrical combination connector slipping during installation. At the same time, a puncture portion 214 is formed on one side of the gasket portion 210. The protruding characteristics of the puncture portion 214 can easily penetrate the oxide layer, paint layer, and electroplating layer on the surface of the electrical contact and closely cooperate with the electrical contact, effectively solving the problem of poor electrical contact.

[0056] In short, the above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention patent.
