Description
Technical Field
[0001] This application relates to the technical field of connectors, and particularly to a wire pin, a wire pin assembly and a connector for a connector. Background Art
[0002] In a connector, a wire pin is required to be used as a conductor. In the prior art, a circular wire pin is produced by turning on a lathe. When producing, a thicker raw material rod is required for turning, so there will be more processing waste, resulting in waste of raw materials and higher production costs.
[0003] For a thinner wire pin, due to its low rigidity, if turning processing is used, it is easy to cause deformation of the wire pin. Usually, a boss with a diameter larger than the main body of the wire pin needs to be processed at the end of the wire pin, which leads to the selection of a thicker raw material rod for turning, resulting in waste of raw materials and higher production costs. Summary of the Invention

[0005] This application proposes a wire pin for a connector. The wire pin includes a wire pin main body. The cross-section of the wire pin main body is circular.

[0027] A axial direction C circumferential direction DETAILED DESCRIPTION
[0028] In order to more clearly explain the above-mentioned purposes, features and advantages of the present application, the specific implementation methods of the present application are described in detail in this section in conjunction with the accompanying drawings. In addition to the various implementation methods described in this section, the present application can also be implemented in other different ways. Without violating the spirit of the present application, those skilled in the art can make corresponding improvements, deformations and substitutions, so the present application is not limited by the specific embodiments disclosed in this section. The scope of protection of the present application shall be subject to the claims.
[0029] In the following description, unless otherwise specified, axial direction A refers to the axial direction of connector 100, and circumferential direction C refers to the circumferential direction of connector 100, wherein the axial direction of connector 100 is consistent with the axial direction of wire needle assembly 101 and the axial direction of wire needle 1.
[0030] like Figures 1 to 7 As shown, an embodiment of the present application provides a connector 100 , which can be used for electrical connection.
[0031] Reference Figure 1 and Figure 2 The connector 100 may be a circular connector, that is, the connector 100 is cylindrical in shape as a whole. At least some of the plurality of thread pins 1 described later may be arranged in a ring shape along the circumferential direction C of the connector 100 .
[0032] The connector 100 includes a wire pin assembly 101, which includes a plurality of wire pins 1 and a wire pin fixing member 2, wherein the plurality of wire pins 1 are connected to the wire pin fixing member 2. The wire pins 1 are made of a conductive material, for example, the wire pins 1 may be made of copper or a copper alloy.
[0033] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the wire needle 1 includes a wire needle body 11. The wire needle body 11 is needle-shaped, and the cross-section of the wire needle body 11 is circular (including approximately circular). The wire needle body 11 can be made by a drawing process, and the end of the wire needle body 11 does not have a boss structure with a diameter larger than that of the wire needle body 11. It can be understood that using the drawing process to make the wire needle body 11 can reduce waste compared to the turning process, thereby saving raw material costs and making the production cost lower.
[0034] For example, the diameter of the wire needle body 11 can be from 0.4 mm to 2 mm. Further, the diameter of the wire needle body 11 can be 0.5 mm. It can be understood that the diameter of the wire needle body 11 disclosed in this application is only exemplary and not restrictive. Since machining a wire needle with a small diameter by turning requires forming a boss at the end (to prevent the wire needle from deforming during turning), such a boss structure results in the need to select a thicker raw material rod, and more waste will be generated during turning. The drawing process does not require such a boss structure. Therefore, the cost advantage of the wire needle in this application is particularly obvious in the case of a small diameter specification (for example, a diameter of 0.5 mm).
[0035] One end of the wire needle body 11 ( Figure 3 and Figure 4 the right end in Figure 3 and Figure 4 the left end in
[0036] The connection end 12 can be in a tapered shape with a smaller diameter closer to the other end of the wire needle body 11. For example, the connection end 12 can be hemispherical, dome-shaped, etc.
[0037] The welding part 14 can be sheet-shaped. For example, one end of the wire needle body 11 can be extruded to deform the wire needle body 11 into a sheet-shaped welding part 14. The welding part 14 is used for welding with other wires. The sheet-shaped welding part 14 can adapt to the welding requirements of various wire gauges and has high adaptability. It can be understood that in other possible embodiments, the welding part can also have a circular cross-section like the wire needle body 11.
[0038] The wire needle body 11 is provided with one or more fixed mounting parts 13. The fixed mounting parts 13 are provided on the part between the two ends of the wire needle body 11, and the fixed mounting parts 13 protrude from the outer peripheral surface of the wire needle body 11. The fixed mounting parts 13 can axially fix the wire needle 1 relative to the wire needle fixing member 2 and prevent the wire needle 1 from rotating relative to the wire needle fixing member 2.
[0039] Refer to Figure 7, in the present embodiment, the fixed mounting portion 13 can be fin-shaped. The fins can be formed by extruding a cylindrical wire pin body using a shaping tool. Through extrusion, depressions and protrusions can be formed on the outer peripheral surface of the wire pin body, and the protruding portions are the fins. There can be two fins, and the two fins can extend in opposite directions. In the circumferential direction C of the wire pin body 11, the fixed mounting portion 13 can partially protrude from the outer peripheral surface of the wire pin body 11 non-entirely around the circumference.
[0040] The diameters of the remaining portions of the wire pin 1 except for the connection end portion 12, the fixed mounting portion 13, and the welding portion 14 can be the same.
[0041] As Figures 3 to 5 shown, the wire pin fixing member 2 can be cylindrical, and the wire pin fixing member 2 can be provided with a plurality of wire pin mounting holes 21. The wire pin mounting holes 21 can penetrate the wire pin fixing member 2 along the axial direction A of the wire pin fixing member 2. A plurality of wire pins 1 can pass through the wire pin mounting holes 21 of the wire pin fixing member 2 along the axial direction A of the wire pin fixing member 2, and both ends of the wire pin 1 protrude from both ends of the wire pin fixing member 2. At least some of the plurality of wire pin mounting holes 21 can be arranged in a ring along the circumferential direction C of the wire pin fixing member 2.
[0042] The wire pin mounting hole 21 can include a small-diameter hole 211, a large-diameter hole 212, and a stepped portion 213. The small-diameter hole 211 can be a circular hole, the large-diameter hole 212 can be a rectangular hole or an elliptical hole, the length of the cross-section of the large-diameter hole 212 can be greater than the diameter of the small-diameter hole 211, the width of the cross-section of the large-diameter hole 212 can be greater than the diameter of the small-diameter hole 211, and the small-diameter hole 211 and the large-diameter hole 212 can be connected by the stepped portion 213. The large-diameter hole 212 can be located at one axial end portion of the wire pin mounting hole 21 ( Figure 4 and Figure 5 the right end portion in), the small-diameter hole 211 can be located at the other axial end portion of the wire pin mounting hole 21 ( Figure 4 and Figure 5 the left end portion in).
[0043] The inner diameter of the small-diameter hole 211 can be the same as the outer diameter of the wire pin body 11, there is no gap between the wire pin body 11 and the small-diameter hole 211, and there can be a gap between the wire pin body 11 and the large-diameter hole 212. For example, both the length and width of the cross-section of the large-diameter hole 212 are greater than the outer diameter of the wire pin body 11. The fixed mounting portion 13 can be located in the small-diameter hole 211 of the wire pin mounting hole 21. For example, it is in interference fit with the hole wall to fixedly connect the wire pin 1 to the wire pin fixing member 2.
[0044] Referring to Figure 3 and Figure 4, a plurality of wire pins 1 can be arranged in a ring along the circumferential direction C of the wire pin fixing member 2. The ring-arranged wire pins 1 can form one or more rings. For example, in this embodiment, a plurality of wire pins 1 can form two rings. The outer ring can include 10 wire pins 1, and the inner ring can include 4 wire pins 1. It can be understood that the number of wire pins 1 is only exemplary. In other possible embodiments, the number of wire pins and the number of rings formed by the arrangement may not be limited by the above embodiments.
[0045] The wire pins for the connector of the present application are made by a drawing process. Compared with the wire pins made by a turning process, the boss structure at the end is omitted. Therefore, thinner raw materials can be used to process the wire pins, reducing material waste and having a lower production cost. Especially for the connectors of disposable devices (such as the connectors of disposable medical devices), the wire pins of the present application can effectively reduce the cost by about 25%. The production efficiency of the drawing equipment is higher than that of the turning equipment, and the wire pins of the present application can also shorten the processing time.

Those skilled in the art can make various modifications to the above embodiments of the present application under the teaching of the present application without departing from the scope of the present application.

For the case where the number of components or members shown in the drawings and / or described in the specification is a specific number such as two, three, four, etc., this specific number is usually exemplary rather than restrictive, and it can be understood as a plurality, that is, two or more. However, this does not mean that the present application excludes the case of one.
