Description

Technical Field

[0001] The present invention relates to an electrical connector. Background Art

[0002] Since electronic devices are gradually moving towards a miniaturized structure, the space inside the device available for placing electrical connectors is gradually becoming narrower. In order to fully adapt to the aforementioned limited space, the corresponding electrical connectors need to be designed towards miniaturization.

[0003] However, the wiring method of existing electrical connectors that are adapted still maintains consistency with the insertion axis, so the length thereof cannot be effectively shortened. Therefore, there is a design requirement for an electrical connector for a miniaturized structure that does not affect its electrical connection relationship, and thus it has emerged accordingly. Summary of the Invention

[0004] The present invention provides an electrical connector, in which a cable is welded to a terminal horizontally, thereby effectively reducing the size of the electrical connector.

[0005] The electrical connector of the present invention is used for welding a cable. The electrical connector includes an insulating body, a plurality of terminals, and a housing. The terminals are arranged horizontally and disposed in the insulating body. Each terminal has a docking section, a connecting section, and a welding section. The housing is assembled to the insulating body to form an interface for docking with another electrical connector. The docking section is adjacent to the interface, and the welding section is away from the interface, wherein the cable is welded horizontally to the welding section of at least one of the terminals.

[0006] Preferably, the above-mentioned horizontal direction and the insertion axis of the electrical connector are non-parallel to each other.

[0007] Preferably, the above-mentioned horizontal direction is orthogonal to the insertion axis of the electrical connector.

[0008] Preferably, the above-mentioned welding section is bent twice relative to the connecting section.

[0009] Preferably, the above-mentioned cable includes a power core wire and two ground core wires.

[0010] Preferably, the above-mentioned terminals include a pair of power terminals and a pair of ground terminals. The power terminals are located between the ground terminals. The power terminals are welded to the power core wire, and the ground terminals are respectively welded to the ground core wires.

[0011] Preferably, the above-mentioned terminals have the same bending structure.

[0012] Preferably, the above-mentioned terminals include a pair of power terminals and a pair of ground terminals. One of the power terminals and one of the ground terminals are disposed in the insulating body in the same configuration orientation, and the other power terminal and the other ground terminal are disposed in the insulating body in another configuration orientation. The difference between the two configuration orientations is that the terminals are rotated 180 degrees around the insertion axis of the electrical connector.

[0013] Preferably, after the welding section is bent relative to the connecting section, a plane is formed, and the interface is located on another plane, and the two planes are parallel to each other.

[0014] Preferably, after the welding section is bent relative to the connecting section, a plane is formed, and the terminal is located on another plane, and the two planes are orthogonal to each other.

[0015] Based on the above, the electrical connector for welding to the cable divides its terminals into a docking section, a connecting section, and a welding section, so that the welding section of each terminal allows the cable to be welded to the corresponding terminal laterally, and the lateral direction is the arrangement direction of these terminals. Accordingly, the connection process of lateral welding can effectively reduce the size of the electrical connector along its insertion axis, and at the same time maintain its due electrical connection function, thereby enabling the electrical connector to better meet the structural characteristics of miniaturization.

[0038] Figure 1A It is a schematic diagram of an electrical connector according to an embodiment of the present invention. Figure 1B Shown from another perspective Figure 1A of the electrical connector. Figure 2 It is a schematic diagram of the assembly of some components of the electrical connector in FIG. 1. At the same time, rectangular coordinates X - Y - Z are provided to facilitate the description of the components. Please refer to Figure 1A , Figure 1B and Figure 2 simultaneously. In this embodiment, the electrical connector 100 is used to weld the cable 200. The electrical connector 100 includes an insulating body 110, a plurality of terminals 120, and a housing 130. The terminals 120 are arranged horizontally and disposed in the insulating body 110. Each terminal 120 has a docking section 121, a connecting section 122, and a welding section 123. The housing 130 is assembled to the insulating body 110 to form an interface A1, which is used to dock with another electrical connector (not shown). For the terminal 120, its docking section 121 is adjacent to the interface A1, and the welding section 123 is away from the interface A1, where the cable 200 is welded to the welding section 123 of at least one of the terminals 120 horizontally.

[0039] Furthermore, the housing 130 is sleeved outside the insulating body 110 to cover a part of the insulating body 110 and a part of the terminals 120, and its interface A1 is located on the plane P2. Here, the electrical connector 100 takes the X - axis as its insertion axis, and the interface A1 is located on the Y - Z plane. Accordingly, the terminals 120 in this embodiment are arranged along the Y - axis, that is, the aforementioned horizontal direction, and thus the horizontal direction and the insertion axis of the electrical connector 100 are in a non - parallel state with each other. Furthermore, the aforementioned horizontal direction is substantially orthogonal to the insertion axis of the electrical connector 100.

[0040] Moreover, as Figure 2 shown, in order to effectively reduce the length of the electrical connector 100, that is, to reduce the size of the electrical connector 100 along the X - axis, the cable 200 in this embodiment needs to be welded to the welding section 123 of the terminal 120 in the aforementioned horizontal direction. Specifically, Figure 3 is Figure 1ASchematic diagram of one terminal of the electrical connector. Please refer to Figure 2 and Figure 3 , in this embodiment, the terminal 120 includes power terminals T2, T3 and ground terminals T1, T4, and the cable 200 includes at least one power core wire C2 and at least one ground core wire C1, C3 (here, one power core wire C2 and two ground core wires C1, C3 are taken as examples). Accordingly, the power core wire C2 is correspondingly welded on the power terminals T2, T3, and the ground core wires C1, C3 are respectively correspondingly welded on the ground terminals T1, T4.

[0041] From Figure 3 it can be seen that the terminal 120 is formed by stamping and bending a conductive metal plate. In particular, in order to facilitate both the foregoing manufacturing process and the subsequent improvement of the bonding property with the insulating body 110, the docking section 121 and the connecting section 122 of this embodiment are substantially located on the same axis, and the main plane of the welding section 123 deviates from the axis where the docking section 121 and the connecting section 122 are located. Here, the welding section 123 includes a first bending section B1 extending from the connecting section 122, and a second bending section B2 extending from the first bending section B1. That is to say, the welding section 123 is substantially bent twice relative to the connecting section 122, and the second bending section B2 can be regarded as being separated from the connecting section 122. Here, the welding section 123 is horizontal, and the welding section 123 and the connecting section 122 are non-parallel to each other.

[0042] Furthermore, please refer to Figure 2 and Figure 3 simultaneously, it can be clearly seen that the four terminals 120 of the electrical connector 100 in this embodiment can be completed with only a single terminal structure, that is, these terminals 120 have the same bending structure. Therefore, when manufacturing, only one type of terminal 120 with the same structural shape needs to be manufactured, and then the four terminals 120 with the same structure can be arranged and combined to form what is required for the electrical connector 100. Here, in order to enable the four terminals 120 to be smoothly arranged together, the power terminal T2 and the ground terminal T1 are arranged on the insulating body 110 in the same configuration orientation, and the power terminal T3 and the ground terminal T4 are arranged on the insulating body 110 in another configuration orientation. The difference between the two configuration orientations is that the terminal 120 rotates 180 degrees around the insertion axis (that is, the X-axis) of the electrical connector 100. For example, the welding section 123 of the power terminal T2 and the ground terminal T1 is bent from top to bottom, while the power terminal T3 and the ground terminal T4 are bent from bottom to top.

[0043] In addition, please refer to Figure 1B and Figure 2It can be seen that each welding section 123 of the terminal 120 in this embodiment is formed by bending from the connection section 122 to form a plurality of planes, and these planes are located on the plane P1, the aforementioned interface A1 is located on the plane P2, and the terminal 120 is located on the plane P3, where the plane P1 is orthogonal to the plane P3, and the plane P1 is parallel to the plane P2. However, the bending angle of the welding section 123 is not limited here. That is to say, in other embodiments not shown, such as Figure 3 as shown, the second bending section B2 of the welding section 123 only needs to be in a non-parallel state with the aforementioned plane P3 and in a non-orthogonal state with the plane P2, and the cable 120 can be transversely welded to the welding section 123. On the other hand, the welding direction of the cable 120 is not limited in this embodiment. Taking Figure 2 as an example, it is welded to the terminal 120 from left to right. In other embodiments not shown, the cable 120 can also be Figure 2 welded in a top-down, right-to-left or bottom-up welding direction. In other words, the cable 120 only needs to be welded on the plane P1 where these second bending sections B2 of these welding sections 123 of the terminal 120 are located to achieve the aforementioned transverse welding effect.

[0044] In summary, in the above embodiments of the present invention, the electrical connector divides its terminals into a docking section, a connection section and a welding section, and the welding section of each terminal enables the cable to be transversely welded to the corresponding terminal, and the transverse direction is the arrangement direction of these terminals. Accordingly, the connection process of transverse welding can effectively reduce the size of the electrical connector along its insertion axis, and at the same time maintain its due electrical connection function, so that the electrical connector can better meet the structural characteristics of miniaturization.

[0045] Furthermore, these terminals of the electrical connector have the same structural shape, that is, the terminals are stamped and bent with the same conductive metal plate. After extending the first bending section from the connection section, the second bending section is further extended, and the four terminals of the electrical connector are composed of the same-structured terminals with different configuration orientations, and the cable is transversely welded to these second bending sections. Accordingly, the electrical connector only needs to manufacture terminals of a single specification, effectively simplifying the manufacturing process and reducing the manufacturing cost.
