Description

Technical Field

[0001] This utility model relates to the field of data cable connector technology, and in particular to a fixing structure for a data cable connector. Background Technology

[0002] Data cable connectors are the core components for physical connection and signal transmission between electronic devices. With the widespread use of electronic devices, data cable connectors are prone to breakage and poor contact due to frequent bending. Traditional fixing structures mostly use injection molding or metal sleeve crimping, which have the following drawbacks:

[0003] 1) Stress concentration: Stress concentration is easily generated at the rigid connection between the injection molded body and the cable due to bending, which leads to cracking in the tail area of ​​the cable.

[0004] 2) Low assembly efficiency: Metal sleeves need to be riveted or welded, which is a complex process and can easily damage the internal core wires;

[0005] 3) Insufficient protection: The lack of coordinated restraint on radial displacement and axial tensile force makes the connector prone to loosening and failure. Therefore, we propose a fixing structure for the data cable connector. Utility Model Content

[0006] In view of the problems of stress concentration, low assembly efficiency and insufficient protection in the existing data cable connector fixing structure, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A fixing structure for a data cable connector includes an outer plug mold, an inner plug mold, a cable, a tinplate fixing structure, copper foil, and a connector.

[0009] The inner mold of the plug is nested inside the outer mold of the plug. The core wire of the cable passes through the inner mold of the plug and extends to the plug body area of ​​the outer mold of the plug. The end of the core wire is connected to a connector, and the core wire is welded to the metal contact of the connector for conduction.

[0010] The tinplate fixing structure covers the outside of the cable and includes a tinplate lower cover and a tinplate upper cover that interlock with each other.

[0011] As a technical solution for the fixing structure of the data cable connector described in this utility model, the tinplate lower cover includes symmetrically arranged tinplate rivet feet, convex buckle positions, lower avoidance areas, and baffle areas.

[0012] The tinplate cover includes a tinplate cover plate, a through hole fastener, an upper clearance area, and a stop area.

[0013] As a technical solution for the fixing structure of the data cable connector of this utility model, the convex buckle is stamped and formed on both sides of the lower tinplate cover, the through hole buckle is opened on the side wall of the upper tinplate cover, and the convex buckle and the through hole buckle form an interference fit mechanical locking structure.

[0014] As a technical solution for the fixing structure of the data cable connector of this utility model, the lower avoidance area and the upper avoidance area together constitute the radial avoidance space of the cable, and the baffle area extends vertically to form the cable entrance limiting structure.

[0015] As a technical solution for the fixing structure of the data cable connector described in this utility model, the stop area is a folded structure at the end of the tinplate cover, and its inner wall is fitted and positioned against the outer wall of the plug mesh tail area of ​​the plug outer mold.

[0016] As a technical solution for the fixing structure of the data cable connector described in this utility model, the plug tail area of ​​the plug outer mold has a tapered shrinkage structure, the outer diameter of which is smaller than that of the plug body area and is transitionally connected to the end of the tinplate fixing structure.

[0017] As a technical solution for the fixing structure of the data cable connector of this utility model, the baffle area and the stop area form an axially offset layout, the baffle area restricts the radial displacement of the cable, and the stop area restricts the axial displacement of the plug outer mold.

[0018] Compared with the prior art, the present invention has at least the following beneficial effects:

[0019] 1. This utility model, through the snap-fit ​​design of the convex buckle of the tinplate lower cover and the through hole buckle of the tinplate upper cover, can achieve welding-free assembly, reduce process complexity, and avoid the squeezing damage to the core wire caused by the traditional crimping process.

[0020] 2. This utility model, by adopting a combination of radial clearance space and conical mesh tail area, can transform bending stress from local concentration to gradient release, and at the same time improve the crack resistance of the plug mesh tail area to adapt to high-frequency plugging and unplugging scenarios.

[0021] 3. This utility model, by adopting an axially staggered layout of the baffle area and the stop area, simultaneously restricts the radial displacement of the cable and the axial displacement of the plug, which can improve the tensile strength of the cable and meet the industrial-grade tensile strength standard.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-4 A fixing structure for a data cable connector is provided, which includes an outer plug mold 1, an inner plug mold 2, a cable 3, a tinplate fixing structure 4, a copper foil 5, and a connector 6.

[0031] The inner mold 2 of the plug is nested inside the outer mold 1 of the plug. The core wire 301 of the cable 3 passes through the inner mold 2 of the plug and extends to the plug body area 101 of the outer mold 1 of the plug. The end of the core wire 301 is connected to the connector 6, and the metal contacts of the core wire 301 and the connector 6 are welded and connected.

[0032] The tinplate fixing structure 4 covers the outside of the cable 3 and includes a tinplate lower cover 41 and a tinplate upper cover 42 that interlock with each other. In application, the combination design of the plug outer mold 1 and plug inner mold 2 nested structure with the tinplate fixing structure 4 achieves double fixing. At the same time, the layout of the plug inner mold 2 nested with the plug outer mold 1 forms a gradient stress buffer, avoiding the rigid connection of injection molding. The tinplate lower cover 41 and tinplate upper cover 42 interlock with the cable 3, which can replace the traditional riveting / welding process to reduce the risk of thermal damage to the core wire 301.

[0033] Reference Figure 3 and Figure 4 The tinplate lower cover 41 includes symmetrically arranged tinplate rivet feet 411, protruding buckle positions 412, lower clearance area 413, and baffle area 414.

[0034] The tinplate cover 42 includes a tinplate cover plate 421, a through hole fastener 422, an upper clearance area 423, and a stop area 424.

[0035] The convex buckle 412 is stamped on both sides of the tinplate lower cover 41, and the through hole buckle 422 is opened on the side wall of the tinplate upper cover 42. The convex buckle 412 and the through hole buckle 422 form an interference fit mechanical locking structure. In application, the interference fit between the convex buckle 412 and the through hole buckle 422 and the mechanical locking structure provide a stable locking force, avoiding deformation errors caused by metal sleeve pressing. The stamping process can improve assembly efficiency and eliminates the need for welding equipment.

[0036] Reference Figures 1-4 The lower avoidance area 413 and the upper avoidance area 423 together constitute the radial avoidance space of the cable 3. The baffle area 414 extends vertically to form the cable 3 entrance limiting structure. The stop area 424 is the folded structure at the end of the tinplate cover 42. Its inner wall fits and is positioned against the outer wall of the plug mesh tail area 102 of the plug outer mold 1. In application, the design of the radial avoidance space and the limiting structure allows the cable 3 to swing within a certain range and disperse bending stress. At the same time, the baffle area 414 and the stop area 424 form an axial misalignment constraint to limit the displacement of the cable 3.

[0037] Reference Figures 1-4 The plug tail area 102 of the plug outer mold 1 has a tapered shrinkage structure. Its outer diameter is smaller than that of the plug body area 101 and it is transitionally connected to the end of the tinplate fixing structure 4. The baffle area 414 and the stop area 424 form an axially misaligned layout. The baffle area 414 restricts the radial displacement of the cable 3, and the stop area 424 restricts the axial displacement of the plug outer mold 1. In application, the tapered plug tail area 102 is transitionally connected to the end of the tinplate. Its tapered shrinkage structure improves the bending angle of the wire. At the same time, the axially misaligned layout works together to resist external forces in multiple directions, which can reduce the probability of cracking of the plug tail area 102.

[0038] The working principle of this utility model is as follows: The core wires 301 are arranged in color sequence and inserted into the guide groove of the plug inner mold 2, with their ends corresponding to the solder pads of the connector 6. An external constant-temperature soldering station is used for soldering to ensure full solder joints without any cold solder joints. A continuity test is then performed. Next, the protruding buckle 412 of the tinplate lower cover 41 is aligned with the through-hole buckle 422 of the tinplate upper cover 42, and pressure is applied to complete the interference fit. At this time, a pre-reserved gap is left between the lower clearance area 413 and the upper clearance area 423, allowing... The cable 3 swings slightly in the radial direction, while the baffle area 414 of the tinplate lower cover 41 is vertically inserted into the cable 3 inlet. The stop area 424 of the tinplate upper cover 42 is folded over and fits against the outer wall of the plug tail area 102 to form an axial limit. Then, the plug inner mold 2 is nested into the plug body area 101 of the plug outer mold 1 and fixed by welding with external ultrasonic equipment. Silicone is injected at the connection between the plug tail area 102 and the tinplate end to form a flexible stress buffer layer, thus completing the assembly of the data cable connector.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
