Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal block technology, and in particular to an embedded terminal block that integrates crimping and welding. Background Technology
[0002] Terminal blocks are widely used to connect cables and conductive components. Currently, there are two methods for connecting and fixing terminals to cables: crimping and welding. These are suitable for conventional and complex scenarios such as high temperatures, respectively. Therefore, terminal blocks are designed with either welding or crimping structures depending on the application. Generally, a single terminal block cannot be used for both welding and crimping fixing methods simultaneously. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides an integrated crimping and welding terminal, which not only meets the needs of crimping cables in conventional working environments, but also allows for the use of welding cups to weld and fix the core wires in complex working environments such as high temperatures. This facilitates the selection of better wire assembly processes according to actual usage scenarios, ensuring the stability of cable connections and the need for efficient signal transmission. It is convenient to use, and the integrated structure of the embedded terminal is simple, easy to process, and has low production costs.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An embedded terminal that integrates crimping and welding has a cable fixing end and a conductive connection end at its two ends. The cable fixing end is provided with a hollow column for crimping the wire core, and the end of the hollow column is provided with a welding cup for welding the wire core. The cable fixing end, the conductive connection end, the hollow column and the welding cup are integrally formed.
[0006] As a further explanation of the above technical solution:
[0007] In the above technical solution, the welding cup is an elliptical ring or a semi-elliptical ring formed by obliquely cutting the end of the hollow column.
[0008] In the above technical solution, the side wall of the hollow column is provided with an observation hole for viewing the wire core.
[0009] In the above technical solution, a positioning protrusion and one or more limiting slots are set on the outer wall of the embedded terminal. The positioning protrusion is located in the middle of the embedded terminal, and all the limiting slots are located between the positioning protrusion and the conductive connection end.
[0010] In the above technical solution, each of the limiting slots is an annular structure and is arranged axially on the outer wall of the embedded terminal.
[0011] In the above technical solution, the outer diameter of several of the limiting slots decreases sequentially along the axial direction, and the outer diameter of the limiting slot closest to the positioning protrusion is the largest.
[0012] In the above technical solution, the conductive connection end is a hollow structure, and several axially extending cantilevers are formed on its sidewall along the circumferential direction.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a hollow column and a welding cup at the cable fixing end, it can not only meet the needs of crimping cables in conventional working environments, but also meet the needs of welding and fixing the core wire in complex working environments such as high temperature. It is convenient to select a better wire assembly process according to the actual use scenario, ensuring the stability of the cable connection and the need for efficient signal transmission. It is easy to use, and the integrated structure of the embedded terminal is simple, easy to process, and has a low production cost. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.
[0018] The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. In the description of this application, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "several" or "more than" means two or more, unless otherwise explicitly specified. In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or it can include contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of a second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" of a second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0019] like Figure 1-2 As shown, the embedded terminal is a combination of crimping and welding. The two ends of the embedded terminal are a cable fixing end 10 and a conductive connection end 20, respectively. The cable fixing end 10 is provided with a hollow column 1 for crimping the wire core, and the end of the hollow column 1 is provided with a welding cup 2 for welding the wire core. The cable fixing end 10, the conductive connection end 20, the hollow column 1 and the welding cup 2 are integrally formed.
[0020] This utility model, by setting a hollow column 1 and a welding cup 2 at the cable fixing end 10, can not only meet the needs of crimping cables in conventional working environments, but also meet the needs of welding and fixing the core wires in complex working environments such as high temperature. It is convenient to select a better wire assembly process according to the actual use scenario, ensuring the stability of the cable connection and the need for efficient signal transmission. It is easy to use, and the integrated structure with embedded terminals is simple, easy to process, and has a low production cost.
[0021] Preferably, the welding cup 2 is an elliptical ring or a semi-elliptical ring formed by obliquely cutting the end of the hollow column 1.
[0022] Preferably, the hollow column 1 has an observation hole 3 on its side wall for viewing the wire core.
[0023] When crimping the wire, you can check whether the wire core is inserted in place through the observation hole 3. This ensures that the wire core of sufficient length can be pressed when crimping the hollow column 1, thus preventing the cable from coming loose.
[0024] Preferably, the outer wall of the embedded terminal is provided with a positioning protrusion 30 and one or more limiting slots 40, the positioning protrusion 30 is located in the middle of the embedded terminal, and all the limiting slots 40 are located between the positioning protrusion 30 and the conductive connection end 20.
[0025] Preferably, each limiting slot 40 is an annular structure and is arranged axially on the outer wall of the embedded terminal.
[0026] Preferably, the outer diameter of the plurality of limiting slots 40 decreases sequentially along the axial direction, and the outer diameter of the limiting slot 40 closest to the positioning protrusion 30 is the largest.
[0027] In this embodiment, a limiting slot 40 with different diameters is provided on one side of the positioning protrusion 30. When the embedded terminal is inserted into the accessory, the two limiting slots 40 will be stuck on the inner wall of the accessory to perform multi-point interference, and the clamping effect increases according to the insertion depth of the conductive connection end 20, which is convenient for fixing the position after insertion and has a good feel.
[0028] Preferably, the conductive connection end 20 is a hollow structure, and several axially extending cantilever 4 are formed on its sidewall along the circumferential direction.
[0029] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
