Description

Technical Field

[0001] The utility model relates to the technical field of wire harness structural parts, in particular to a connector wiring structure for convenient and quick wiring. Background Art

[0002] Data cables are key components that connect components and power sources in equipment. Their core function is to achieve data transmission, communication and power supply between components. There are many types of data cables and connectors. Therefore, in actual use, the connection between connectors and wiring harnesses is often not convenient or fast enough.

[0003] In the existing technology, data connection cables usually include wires and terminal connectors. The wires are mostly parallel extension structures, and terminal connectors are provided on both ends of the wires to connect with electronic components to realize data transmission. In order to optimize the cable forming process and control production costs, at present, most types of data connection cables use press-fit technology to realize the assembly and fixation of wires on terminal connectors. However, the design of traditional cable connectors is relatively simple. During the press-fitting process of the wires on the terminal connectors, if the press-fitting force is too large, it is easy to damage the wires or the plastic shells of the terminal connectors, resulting in a decrease in the yield rate; if the press-fitting force is too small, it may cause the wires to loosen and deviate at the connectors, which will not only affect the stability of data transmission, but may even cause transmission interruption, thereby shortening the service life of related components, and in severe cases, may also cause damage to the equipment. Utility Model Content

[0004] The technical problem solved by the utility model is to provide a connector wiring structure that is convenient and quick to wire, so as to solve the shortcomings of the above-mentioned background technology.

[0005] The technical problem solved by the utility model is achieved by the following technical solutions:

[0006] A connector wiring structure for convenient and quick wiring, comprising a wiring hole arranged on a terminal connector, the wiring hole having a hole diameter larger than the wire to be assembled, and a press-fit hole communicating with the wiring hole cavity is opened on the radial outer side of the wiring hole at the terminal connector;

[0007] An elastic crimping piece is fixedly arranged in the wiring hole, and the elastic crimping piece includes a base and a press-fit spring sheet, the base is U-shaped to match the wire diameter to be assembled, the main body of the press-fit spring sheet is an arc-shaped spring sheet, and protrusions are formed on both sides of the bottom surface of the arc-shaped spring sheet; ear plates are formed on both sides of the arc-shaped spring sheet, and the arc-shaped spring sheet is movably connected to the ear plates, and the press-fit spring sheet is fixedly connected to the top of both sides of the base through the ear plates on both sides;

[0008] The press-fitting hole is arranged correspondingly on the top surface of the arc-shaped spring piece. The arc-shaped spring piece is initially in an upward convex arc shape. After the top surface is subjected to a pressure greater than the press-fitting threshold, it is converted into an upward convex arc shape and maintained. The protrusion is clamped on the surface of the wire to be assembled when the arc-shaped spring piece is in a downward convex arc shape.

[0009] As a further limitation, the cross-sectional profile of the wiring hole is rectangular, circular or elliptical.

[0010] As a further limitation, when there are multiple wiring holes on the terminal connector, the multiple wiring holes are arranged in a single row or double rows on the terminal connector, and the press-fit holes are arranged on the top surface or the bottom surface of the wiring holes.

[0011] As a further limitation, the wiring hole on the terminal connector is a variable diameter structure in the axial direction of the hole, and when the device insertion side of the terminal connector is the outer side, the wiring hole is formed with an inner neck on the inner side of the hole cavity for limiting the end face of the elastic crimping part;

[0012] The base of the elastic crimping piece is fixed in the wiring hole by inner neck limiting at both sides and the bottom surface.

[0013] As a further limitation, the press-fit spring is formed of spring steel, and the thickness increases continuously from both sides to the middle. The press-fit threshold is positively correlated with the thickness of the press-fit spring. The press-fit spring matches different press-fit thresholds through different thicknesses to adapt to wires requiring different clamping forces.

[0014] As a further limitation, the surface of the protrusion is formed with anti-slip patterns.

[0015] As a further limitation, a conical spike capable of piercing into the spiked wire is formed on the inner side of the surface of the protrusion.

[0016] Beneficial effect: The utility model has a connector wiring structure that is convenient for quick wiring. By introducing the design of an elastic crimping part, when it is necessary to connect the wire, the wire only needs to be inserted into the wiring hole, and then a tool is used to apply a pressure greater than the pressing threshold on the outside of the pressing hole to deform the pressing spring sheet, thereby achieving a firm clamping of the wire, and realizing a fast, stable and lossless pressing of the wire, which not only simplifies the wiring process, but also reduces the influence of human factors on the pressing effect, and improves production efficiency and yield rate; in addition, by adjusting parameters such as the shape and size of the wiring hole and the position of the pressing hole, it can adapt to wires of different specifications and types, and has better adaptability to different types of terminal connectors. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a schematic diagram of a preferred embodiment of the utility model.

[0018] Figure 2 for Figure 1 Figure 2 shows the in-hole assembly style for the wiring hole in the middle.

[0019] Among them: 1. Terminal connector base; 2. Wiring hole; 3. Inward neck; 4. Ear plate; 5. Arc-shaped spring; 6. Bump; 7. Wire; 8. Base. DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0021] See also Figure 1 A preferred embodiment of a connector wiring structure for convenient and quick wiring, the terminal connector base 1 used in the connector wiring structure of this embodiment is a PHDS2.0mm connector, and twelve wiring holes 2 are formed on the terminal connector base 1. The twelve wiring holes 2 are arranged in double rows on the terminal connector base 1, with 6 holes in each row, and the terminal connector base 1 has press-fit holes connected to the wiring hole cavities formed on the top surface of the upper row of wiring holes 2 and the bottom surface of the lower row of wiring holes 2.

[0022] In this embodiment, the structural style of a single wiring hole 2 is described by taking the upper row of wiring holes as an example. The cross-sectional profile of the wiring hole 2 is a rectangle. Such a design makes the wiring hole 2 easier to process and can also adapt to wires of various shapes. The rectangular cross-section is a variable diameter structure in the axial direction of the wiring hole 2. The variable diameter part includes a fixed part with a complete cross-sectional size and an inward-retracted neck 3. The fixed part is used to fix the wire 7. Its structural style is as follows: Figure 2 and the inner neck 3 is arranged on the insertion side of the guide 7.

[0023] In each wiring hole 2, there is an elastic crimping part, which consists of a base 8 and a press-fit spring 5. The base 8 is U-shaped, and its size matches the wire diameter of the wire 7 to be assembled, ensuring that the wire 7 can be smoothly inserted. The two side edges and the bottom edge of the base 8 are against the bottom side of the wiring hole 2 on the inner side, and against the inner surface of the inner neck 3 on the outer side, so as to limit and fix the end face of the base 8 through the inner neck 3 to prevent it from being offset or falling off during the press-fitting process.

[0024] The main body of the press-fitted spring sheet is an arc-shaped spring sheet 5, which has sufficient elasticity and can be deformed when subjected to external force; the arc-shaped spring sheet 5 is formed with protrusions 6 on both sides of the lower surface, and the surface of the protrusion 6 is formed with anti-slip patterns. The anti-slip patterns are set to increase the friction with the surface of the wire 7, thereby improving the stability of clamping the wire 7.

[0025] The outer sides of the arc-shaped spring piece 5 are connected to ear plates 4, and the ear plates 4 are fixedly connected to the tops of the two sides of the base 8. The base 8 is used to ensure that the position height of the arc-shaped spring piece 5 remains unchanged by supporting the outer edges of the ear plates 4. At the same time, the initial position of the arc-shaped spring piece 5 is an upward convex arc (such as Figure 2 When the wire needs to be pressed, the staff inserts the wire to be assembled from the outside of the wiring hole 2 until the wire is pushed into the elastic crimping part area; then, the staff can use a pressure tool on the outside of the press-fit hole to apply pressure to the top surface of the arc-shaped spring leaf 5. When the applied pressure exceeds the press-fit threshold, the arc-shaped spring leaf begins to deform, gradually changing from the initial convex arc shape to a convex arc shape (such as Figure 2 This deformation process causes the protrusions 6 on both sides of the lower surface of the arc-shaped spring piece 5 to be tightly clamped on the surface of the wire, and cooperates with the downward pressure of the arc-shaped spring piece 5 to clamp and fix the wire 7.

[0026] In order to improve the stability of the protrusion 6 in clamping the wire 7, in different embodiments, the protrusion 6 can be formed with anti-slip patterns on the surface to increase the friction with the surface of the wire 7, or conical spikes can be formed at the contact surface between the protrusion 6 and the wire 7. The conical spikes can be pierced into the surface of the wire 7 by pressure when pressed down by a pressure tool, thereby further increasing the friction with the wire 7.

[0027] It is worth noting that, since the thickness of the pressed spring sheet increases continuously from both sides to the middle, the pressed spring sheet can produce uniform deformation when subjected to pressure, ensuring the uniformity and stability of the wire clamping. At the same time, the press-fitting threshold is positively correlated with the thickness of the pressed spring sheet, which means that by adjusting the thickness of the pressed spring sheet, it is possible to adapt to the needs of different clamping forces to meet the press-fitting requirements of wires of different specifications and types. The above shows and describes the basic principles, main features and advantages of the utility model. Technicians in this industry should understand that the utility model is not limited to the above-mentioned embodiments. The above-mentioned embodiments and descriptions are only to illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will also have various changes and improvements, and these changes and improvements all fall within the scope of the utility model to be protected. The scope of protection claimed by the present utility model is defined by the attached claims and their equivalents.
