Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment wiring, in particular to a high-current contact couple. Background Art

[0002] Contact couples are an accessory product widely used in the electronics industry to achieve electrical connections. The connection between contact couples and wires is mainly through welding or crimping. Conventional contact couples have a wire crimping barrel or welding cup, which can be connected to a wire. However, the current carrying capacity of a single wire is very limited. When the current carrying requirement is high or multiple outputs are required, a single wire is difficult to meet the current carrying requirement. At present, there is also a design structure that connects a wire crimping barrel or welding cup to multiple wires at the same time, but this structure can only be applied to the case where a single wire is thinner. When the current carrying requirement of a single wire is not high and the single wire is thin, multiple thinner wires are fixedly connected in a wire crimping barrel or welding cup, and the crimping or welding reliability of each wire can be guaranteed. However, when the current carrying requirement is higher and the current carrying requirement of a single wire is very high, the cross-sectional area of ​​a single wire is very large. Connecting multiple wires with large cross-sectional areas in a wire crimping barrel or welding cup will lead to unreliable crimping or welding of individual wires, which will lead to reduced connection reliability and greater difficulty in wiring operation. Utility Model Content

[0003] The utility model aims to provide a large current contact couple to solve the problems of great wiring difficulty and low connection reliability when the existing contact couple is connected to multiple wires.

[0005] A high-current contact couple comprises a plug-in terminal for plugging into an adapting contact couple and a wiring terminal for connecting a wire. The wiring terminal is a wire crimping barrel or a welding cup. The number of the wiring terminals is greater than the number of the plug-in terminals to achieve electrical connection between multiple wires and the plug-in terminals, thereby achieving current diversion or convergence.

[0006] Furthermore, all the connection terminals are arranged in an array.

[0007] Further, at least two of the terminals have different diameters.

[0008] Furthermore, the high-current contact couple comprises a substrate, and the plug-in terminal and the wiring terminal are respectively arranged on two opposite sides of the substrate.

[0009] Furthermore, the substrate is a rectangular plate, and all the connection terminals are arranged in a matrix on the rectangular plate.

[0010] Furthermore, the axes of the plug-in terminal and the wiring terminal are arranged in parallel.

[0021] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0022] The utility model is an improvement on the existing contact couple, and is mainly used to solve the problem that the wire crimping barrel or wire welding cup of the existing contact couple is suitable for connecting with one wire, but when connecting with multiple wires, the wiring operation is difficult and the connection reliability is low.

[0023] The principle of the high-current contact couple of the utility model is as follows: the high-current contact couple includes a plug-in terminal and a wiring terminal, the plug-in terminal is used to plug with an adapter contact couple, the wiring terminal is used to connect a wire, the wiring terminal is a wire crimping barrel or a welding wire cup, the number of wiring terminals is greater than the number of plug-in terminals, so that the plug-in terminal can be electrically connected to multiple wires at the same time, the high current passing through the plug-in terminal can be dispersed to multiple wires, or the current of multiple wires can be converged to the plug-in terminal, thereby achieving shunting or convergence, meeting the high-current flow requirements. Since a single wiring terminal is used to connect to a single wire, the wiring difficulty is reduced and the connection reliability is improved.

[0024] Embodiment of the utility model high current contact couple:

[0025] like Figure 1-4 As shown, the high-current contact couple includes a plug-in terminal 1 for plugging with an adapter contact couple and a terminal 2 for connecting a wire. The terminal 2 is a wire crimping barrel or a welding cup. The number of the terminal 2 is greater than the number of the plug-in terminal 1 to achieve electrical connection between multiple wires and the plug-in terminal 1, thereby achieving current diversion or convergence. When the terminal 2 is specifically a wire crimping barrel, the inner cavity of the wire crimping barrel constitutes a wire installation cavity for inserting the wire. The wire is inserted into the inner cavity of the wire crimping barrel and fixed by crimping, and the connection reliability is high. Of course, in addition to crimping and fixing with the wire, the terminal can also be welded. For example, in another embodiment, the terminal is a welding cup, and the welding cup is provided with a wire installation port. The welding cup is used to be welded and fixed with the wire.

[0026] The following is an introduction using the example of a wire crimping barrel as the terminal. All wire crimping barrels are arranged in an array so that the wire crimping barrels are arranged neatly and orderly, and a certain gap is maintained between adjacent wire crimping barrels, which is convenient for each wire crimping barrel to be connected to the wire, and the wiring operation is more convenient. The specifications of the wire crimping barrel are set according to the flow size of the corresponding wire. The diameters of all wire crimping barrels can be the same. Of course, the diameters of at least two of the wire crimping barrels can also be different, and each wire crimping barrel can match wires of different specifications as needed. Of course, such a structural arrangement can also be used when the terminal is a welding wire cup. It should be noted here that there is no strict requirement for the arrangement of all terminal terminals. In addition to the array arrangement, any other arrangement form can also be used. For example, when there are three terminal terminals, the three terminal terminals can be arranged in a row, or the three terminal terminals can be arranged in a triangle, and so on.

[0027] The high-current contact couple includes a substrate 3, and the plug-in terminal 1 and the wiring terminal 2 are respectively arranged on opposite sides of the substrate 3. The plug-in terminal 1 and the wiring terminal 2 are separated in space to avoid mutual interference, which is convenient for plugging the plug-in terminal 1 with the adapter contact couple and for connecting each wiring terminal 2 with the wire. In other embodiments, when the shape of the plug-in terminal can meet the terminal arrangement requirements, the plug-in terminal and each wiring terminal can also be directly connected. For example, when the end surface area of ​​the plug-in terminal is large, each wiring terminal can be directly fixed and connected to one end surface of the plug-in terminal.

[0028] The substrate 3 is specifically a rectangular plate, and all the terminals 2 are arranged in a matrix on the rectangular plate. Figure 1 It can be seen that there are six terminals 2, which are arranged in two rows on the rectangular plate, each row including three terminals 2, and the terminals 2 in the same row are arranged at intervals along the length direction of the rectangular plate. In this way, the installation space on the substrate can be fully utilized, and the size of the substrate can be reduced as much as possible on the basis of ensuring that the number of terminals 2 remains unchanged, thereby reducing the volume of the contact pair. Of course, in other embodiments, all the terminals can also be arranged in a row on the rectangular plate or in any other arrangement. In addition to being a rectangular plate, the substrate can also be a circular plate or other shapes, and all the terminals can be evenly distributed on the substrate. There are many deformation structures, which are not listed here one by one.

[0029] The plug end 1 is specifically a plug pin, and the diameter of the plug pin is larger than the diameter of all the wiring terminals 2. The plug pin has a large cross-sectional area, which can ensure the flow capacity of a large current. The plug pin is used to adapt and plug with the socket of the matching contact. Of course, in specific applications, the plug end can also be a socket, which is used to adapt and plug with the pin of the matching contact.

[0030] The axes of the plug terminal 1 and the terminal 2 are arranged in parallel. In this way, the plugging direction of the plug terminal 1 is parallel to the wire access direction of the terminal 2. When connecting the wire to the terminal 2, the wire does not need to be bent. Especially when the current is large, the wire is thicker as a whole and is not easy to bend. Such a structural setting can avoid bending the wire and make the wire connection more convenient. It is understandable that in some application scenarios, the wiring direction is required to be perpendicular to the plugging direction. At this time, the axes of the plug terminal and the terminal can also be arranged vertically to avoid bending the wire and reduce the difficulty of wiring as much as possible. In addition, in specific applications, the terminal can also be in the shape of a bent cylinder.

[0031] The substrate 3 is provided with a positioning structure for positioning and cooperating with the device where the adapting contact couple is located, so as to facilitate positioning of the contact couple when the contact couple is plugged into the adapting contact couple, thereby ensuring the connection reliability with the adapting contact couple. Figure 1-2As shown, a positioning plate 4 is provided on one side of the substrate 3 facing the plug-in end 1. The positioning plate 4 has a positioning portion for positioning and cooperating with the device where the matching contact couple is located. The positioning plate 4 constitutes a positioning structure. The positioning plate is processed on one side of the substrate, which has a simple structure and is easy to process. There are many replacement structures that can be thought of here. For example, in another embodiment, a plurality of positioning protrusions are spaced apart on the same circumference on one side of the substrate facing the plug-in end. The positioning protrusions constitute a positioning structure.

[0032] The utility model has a large current contactor with an integrated structure, and does not need to consider the fixed connection between the components, and has high conductivity reliability. Of course, it can also be a split structure, for example, the plug-in terminal and the base plate are an integrated structure, and each terminal is welded on the base plate. In this way, although the number of parts is large, the processing of a single part is relatively simple.

[0033] The high-current contact couple of the utility model can be electrically connected to multiple wires at the same time, and the high current passing through the plug-in terminal can be dispersed to multiple wires, or the currents of multiple wires can be converged to the plug-in terminal, thereby realizing current diversion or convergence to meet the high current flow demand. Since a single terminal is used to connect to a single wire, the wiring difficulty is reduced and the connection reliability is improved.

All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
