In the prior art, the number of contact points between the terminals and the wire harness is generally small, and it is difficult to change the spacing of the terminal clamps according to the size of the wire harness. Utility Model Content

[0004] In view of this, the present invention provides an electrical connector to solve the problem of having few contact points between the terminals and the wire harness and being unable to change the wire clamping spacing.

[0005] According to a first aspect, this utility model provides an electrical connector, comprising:

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Electrical connectors, also known as circuit connectors or electronic connectors, are used to bridge two electrical components in a circuit, allowing current or signals to flow from one component to another. They are widely used in various electrical circuits to connect or disconnect current or signals. Because electrical connectors are easy to manufacture into standardized components and offer high electrical connection reliability, they are particularly suitable for modular components.

[0030] Electrical connectors typically consist of a plug (male) and a socket (female) that are connected to each other. The plug is generally used to connect wire harnesses and includes a housing and terminals. In the prior art, the number of contact points between the terminals and the wire harness is generally small, and it is difficult to change the spacing of the terminal clamps according to the size of the wire harness.

[0031] To address the aforementioned problems, this specification provides an electrical connector that aims to provide a novel electrical connector capable of solving the problems described above. Please refer to... Figures 1 to 6 The electrical connector includes a plug consisting of a wire harness insertion housing 10 and a plurality of terminals 20.

[0032] The wire harness plug-in housing 10 is provided with a plurality of wire harness plug-in holes 11 for inserting wire harnesses. Each wire harness plug-in hole 11 is provided with a terminal 20. The terminal 20 is connected to the corresponding wire harness plug-in hole 11. That is, the wire harness plug-in housing 10 is provided with a number of wire harness plug-in holes 11 that are equal to and correspond one-to-one with the terminal 20. At the same time, a wire harness end face is formed on the wire harness plug-in housing 10.

[0033] The terminals 20 on the plug are all located on one side of the plug. Each terminal 20 includes an integrally formed welding end face 22 and four wire harness contact feet 21. One end of each wire harness contact foot 21 extends into the corresponding wire harness insertion hole 11, and the other end of each wire harness contact foot 21, which is also the main body of the terminal 20, extends outward from the wire harness insertion hole 11. The other end of each wire harness contact foot 21 is provided with a welding end face 22. All welding end faces 22 are arranged parallel to each other and located on the same horizontal plane. The welding end face 22 is used to mate with the welding surface, for example, to weld with a PCB board.

[0034] In this embodiment, the wire harness insertion hole 11 is configured as a linearly extending through hole, and the terminal 0 is perpendicular to the corresponding wire harness insertion hole 11. The wire harness insertion hole 11 has a clamping end face 12 for fixing the wire harness after insertion. The clamping end face 12 supports and provides a stable end face for the wire harness. The wire harness insertion hole 11 also has an insertion groove 13, which is located on both sides of the clamping end face 12. A connecting block 14 is provided within the insertion groove 13. Insertion components can be inserted into the insertion groove 13, thus fixing the wire harness inserted at the end face. The connecting block 14 ensures the structural strength of the entire wire harness insertion housing 10.

[0035] In this embodiment, the wire harness contact feet 21 on the welding terminal 20 are arranged in pairs, with the two pairs of wire harness contact feet 21 arranged parallel to each other. A wire clamping hole 23 is formed between the two wire harness contact feet 21 in each pair, and the wire clamping hole 23 communicates with the corresponding wire harness insertion hole 11. The wire clamping hole 23 is designed to clamp the wire harness and also allows the spacing of the wire clamping holes on the welding terminal 20 to be adjusted according to the size of the wire harness. A wire clamping assembly can be installed in the wire clamping hole 23, and the wire clamping assembly can slide at the wire clamping hole 23. The slidable wire clamping assembly allows the welding terminal 20 to adjust the spacing of the wire clamping holes according to the size of the wire harness.

[0036] In this embodiment, the welding end face 22 is also provided with an extension surface 221. The extension surface 221 extends outward from the welding end face 22 and is disposed between the two sets of wire harness contact feet 21. The extension surface 221 extends inward from the welding end face and is provided with a wire fixing groove 222. The wire fixing groove 222 provided on the extension surface 221 can also help different terminals 20 separate the wire harness and provide wire clamping holes for the wire harness.

[0037] In this embodiment, the clamp end face 12 is provided with an end fixing surface 121 for fixing the wire harness contact foot 21. The end fixing surface 121 provides a stable mounting surface and support point for the entire terminal 20.

[0038] In this embodiment, a guide surface 15 extends inward on the wire harness plug housing 10. The guide surface 15 is interconnected with the wire harness plug hole 11 and the terminal block 20. The guide surface 15 facilitates the connection of the wire harness, the insertion of various auxiliary components, and the soldering of the terminal block 20.

[0039] The electrical connector of this invention has four wire harness contact feet 21 on the terminal block 20 of the plug for connecting the wire harness. This increases the contact area with the wire harness, and each wire harness contact foot 21 can form a stable contact point. The four wire harness contact feet 21 form multiple contact points, making the contact between the terminal block 20 and the wire harness more stable. This stable contact method between the terminal block 20 and the wire harness, along with the multiple terminal blocks 20 on the plug and the equal number of corresponding wire harness insertion holes 11, allows the entire electrical connector to transmit a larger current. The side of the terminal block 20 extending outward toward the wire harness insertion housing 10 forms a welding end face 22. The welding end face 22 allows the plug to be directly welded to the welding surface, making the welding operation convenient and quick. The wiring holes formed between the wire harness contact feet 21 allow the welding terminals to adjust the spacing of the terminal clamps according to the size of the wire harness, and the spacing can be adjusted based on a quick plug-in and quick pull-out method, making the connection of the wire harness more stable and faster.
