Description

Technical Field

[0001] This utility model relates to the field of ribbon cable connectors, and in particular to a ribbon cable terminal connection structure. Background Technology

[0002] As a signal transmission component, ribbon cables possess advantages such as flexibility and high signal transmission capability, and are widely used in many electronic products with usage increasing year by year. Ribbon cables typically connect to connectors via terminals. Generally, the ribbon cable ends and terminals are assembled together, offering easy insertion and removal, making them convenient to use. Ribbon cables can be moved, bent, and twisted without damaging the wires, and can conform to different shapes and special package sizes. Their only limitation is space constraints. Because they can withstand millions of dynamic bends, ribbon cables are well-suited for interconnected systems with continuous or periodic motion, becoming an integral part of the final product's functionality. The wires in a ribbon cable are generally connected to an external circuit board via connector terminals.

[0003] In existing ribbon cable connectors, the wires are riveted to the terminals. While this connection method can withstand high-frequency vibration and prevent loosening, it results in higher resistance, affecting the overall performance of the ribbon cable connector. Furthermore, due to the small spacing between adjacent wires in the ribbon cable connector, two layers of terminal groups are typically arranged in a cross pattern to increase the spacing between adjacent terminals and prevent crosstalk. This method requires two layers of material tape, increasing the cost of raw materials. Therefore, it is necessary to further improve the existing ribbon cable connector structure. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a ribbon cable terminal connection structure that can effectively solve the problems of high resistance at the connection point of existing ribbon cable connectors, which affects working performance and has high raw material costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A ribbon cable terminal connection structure includes an insulating body, wires, and connecting terminals. Multiple wires are arranged side-by-side, with the front end of each wire embedded in the insulating body. Each connecting terminal includes an integrally formed strip, a connecting portion, and a welding portion. The connecting portion is integrally formed by bending the strip upwards or downwards. Multiple connecting portions are arranged laterally at intervals, with adjacent connecting portions bending in opposite directions. The welding portion extends integrally forward from the front end of the connecting portion. The welding portion is welded to the wires by resistance welding, and the weld joint between the welding portion and the wires is embedded in the insulating body.

[0007] As a preferred embodiment, each wire includes an outer sheath and a conductor, the rear end of which extends backward out of the outer sheath and is welded to the connecting terminal by resistance welding.

[0008] As a preferred embodiment, the connecting terminal is provided with a reinforcing plate, which partially covers the welding part and the connecting part, with the front end of the welding part extending forward beyond the reinforcing plate.

[0009] As a preferred embodiment, the connecting part includes an integrally bent first connecting segment, a second connecting segment, and a main body segment. The main body segment is horizontally arranged, and the first connecting segment and the second connecting segment are respectively connected to the front and rear ends of the main body segment. The first connecting segment and the second connecting segment are respectively connected to the strip and the welding part.

[0010] As a preferred embodiment, the strip is provided with a plurality of positioning holes arranged at intervals.

[0011] As a preferred embodiment, the welded portion is flat.

[0012] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0013] The connecting parts are formed by bending the strip upwards or downwards as a whole. There are multiple connecting parts arranged horizontally at intervals. The bending directions of adjacent connecting parts are opposite. This staggered arrangement increases the spacing between adjacent connecting parts on the same plane. This allows the connection terminals of a single layer of strip to achieve the function of preventing crosstalk, effectively reducing the cost of raw materials. In addition, the welding part is welded to the wire by resistance welding. The resistance welding method greatly reduces the resistance at the connection between the welding part and the wire, avoiding excessive resistance that would affect the performance of the ribbon cable connector.

[0014] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0026] Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a wire 20, and a connecting terminal 30.

[0027] The wires 20 are arranged in a row, and the front end of each wire 20 is embedded in the insulating body 10. In this embodiment, each wire 20 includes an outer sheath 21 and a conductor 22. The rear end of the conductor 22 extends backward out of the outer sheath 21 and is welded to the connecting terminal 30 by resistance welding.

[0028] The connector 30 includes an integrally formed strip 31, a connecting part 32, and a welding part 33. The connecting part 32 is integrally formed by bending the strip 32 upwards or downwards. Multiple connecting parts 32 are arranged laterally at intervals, and the bending directions of adjacent connecting parts 32 are opposite, so that there is a certain interval between adjacent connecting parts 32 on the same plane, thereby realizing the function of preventing signal crosstalk. The welding part 33 extends forward integrally from the front end of the connecting part 32. The welding part 33 is welded to the wire 20 by resistance welding. The resistance welding connection method can effectively reduce the resistance at the connection point and ensure the overall performance of the ribbon cable connector. The welding joint between the welding part 33 and the wire 20 is embedded in the insulating body 10, so that the insulating body 10 seals and protects the welding joint between the welding part 33 and the wire 20, thereby improving its waterproof performance.

[0029] In this embodiment, a reinforcing plate 34 is provided on the connecting terminal 30. The reinforcing plate 34 partially covers the welding part 33 and the connecting part 32. The front end of the welding part 33 extends forward from the reinforcing plate 34. The reinforcing plate 34 is used to strengthen the structural strength of the connecting part 32 and the welding part 33, and to prevent the welding part 33 and the connecting part 32 from bending due to external force during assembly. The connecting part 32 includes a first connecting section 321, a second connecting section 322, and a main body section 323, which are integrally bent. The main body section 323 is horizontally arranged, and the first connecting section 321 and the second connecting section 322 are separate. The front and rear ends of the main body segment 323 are connected separately. The first connecting segment 321 and the second connecting segment 322 are connected to the strip 31 and the welding part 33, respectively. After assembly, the strip 31 needs to be cut off from the connection between the first connecting segment 321 and the main body segment 322. The strip 31 is provided with a plurality of spaced positioning holes 302, which are used to ensure the accuracy of the position of the strip 31 during injection molding. The welding part 33 is flat, and the flat structure makes the welding process between the welding part 33 and the wire 20 more convenient.

[0030] The key design feature of this invention is that the connecting parts are integrally formed by bending the strip upwards or downwards. Multiple connecting parts are arranged horizontally at intervals, with adjacent connecting parts bending in opposite directions. This staggered arrangement increases the spacing between adjacent connecting parts on the same plane, allowing the use of a single-layer strip connector to achieve crosstalk prevention. This effectively reduces raw material costs. Furthermore, the welding part is welded to the wire using resistance welding, which greatly reduces the resistance at the connection between the welding part and the wire, preventing excessive resistance from affecting the performance of the ribbon cable connector.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
