Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a medical connector plug with an assembled structure. Background Art

[0002] For some medical devices, such as some small portable medical devices, the internal space is compact. The internal wiring and structural design may require that the pin lengths of the plug be the same and arranged in a row to better adapt to the space limitations and circuit layout inside the device. Moreover, the pins arranged neatly and with the same length are easier for medical staff or users to identify and operate, reducing the possibility of incorrect insertion or improper operation.

[0003] At present, the composition of such existing plugs mainly includes a flat insulating shell, a row of conductive pins integrally combined and arranged at the front end of the flat insulating shell, and a wire integrally combined with the flat insulating shell and electrically connected to the conductive pins. The flat insulating shell of this kind of structure is generally made by in-mold integral molding. Since the produced insulating shell is in a completely filled state inside, the material cost is relatively high. And if the plug produced by the in-mold molding method is detected to be defective, it cannot be reworked, thus increasing the production cost to a certain extent. In contrast, it is necessary to propose an improved technical solution to solve the above problems. Summary of the Utility Model

A pressing post corresponding to the wire pressing portion is also formed on the upper shell. The upper shell is in pressing and tight cooperation with the wire pressing portion through the pressing post. Fixing sleeves and fixing posts that are longitudinally butted and matched are also provided at the positions of the upper shell and the lower shell corresponding to the first connection hole and the second connection hole.

[0006] Preferably, a positioning groove is provided on the covering edge of the lower shell, and a positioning strip matching the positioning groove is formed on the covering edge of the upper shell.

A clamping post 16 is formed at a position of the lower shell 12 corresponding to the first connection hole 14, and a clamping hole 32 corresponding to the clamping post 16 is provided on the conductive pin 30. The conductive pin 30 is butted against the first connection hole 14 and is fixedly connected to the insulating housing 10 through the docking cooperation of the clamping hole 32 and the clamping post 16. A pressing post 17 corresponding to the wire pressing portion 31 is also formed on the upper shell 11, and the upper shell 11 is in pressing fit with the wire pressing portion 31 through the pressing post 17. Fixing sleeves 18 and fixing posts 19 that are longitudinally butted and matched are also provided at positions of the upper shell 11 and the lower shell 12 corresponding to the first connection hole 14 and the second connection hole 15.

[0026] In the above technical solution, it is provided that the medical connector plug includes an insulating housing 10, a wire 20, and a plurality of conductive pins 30. The insulating housing 10 is set to have a structure of an upper shell 11 and a lower shell 12 that can be disassembled and assembled by itself. The upper shell 11 and the lower shell 12 are initially fixedly covered by using the covering edges 13 at the edges of the upper shell 11 and the lower shell 12 that can be butted and matched. Then, by setting the structure of the fixing sleeves 18 and the fixing posts 19, the fixing sleeves 18 and the fixing posts 19 are fixedly connected, so as to achieve the purpose of fixedly covering the upper shell 11 and the lower shell 12. On this basis, the structure of the clamping hole 32 and the clamping post 16 is also provided to clamp the conductive pin 30, so that the conductive pin 30 can be firmly fixed between the upper shell 11 and the lower shell 12. And further, by setting the pressing post 17 to press the position between the wire 20 and the wire pressing portion 31, the electrical connection between the conductive pin 30 and the wire 20 is firm and reliable. Through this setting, the material consumption of the insulating housing 10 can be reduced to a certain extent. And after the assembly and cooperation, the fixing firmness of the conductive pin 30 and the reliability of the electrical connection between the conductive pin 30 and the wire 20 can be ensured. And after being manufactured, if there are quality problems, etc., it can be disassembled again for a certain degree of rework processing, and some damaged parts can also be recycled separately. Compared with the overall recycling processing, the processing cost and processing time can both be reduced, thus reducing the manufacturing cost to a certain extent.

[0027] Please refer to Figure 3 ,Figure 4 and Figure 6 The upper shell 11 is provided with a plurality of positioning strips 132 that match the positioning strips 131.

If there are quality problems, the upper shell 11 and the lower shell 12 can be pried apart with a special tool. The restriction of the conductive pin 30 is also removed in the process of prying apart, so that the conductive pin 30 can be directly taken out, so that the various parts can be distinguished to achieve targeted rework processing and also facilitate the overall rapid disassembly and assembly.

[0028] See also Figures 3-5 In the first embodiment of the present invention, the conductive pin 30 adopts a traditional structure and is mainly made of metal material. The front part of the conductive pin 30 is a cylindrical structure corresponding to the first connecting hole 14. A transition part 33 is arranged between the front part of the conductive pin 30 and the wire pressing part 31. The wire pressing part 31 has a wire supporting part 311 at the lower end for placing the wire 20 and a wire pressing part 312 located on both sides of the wire supporting part 311 and capable of bending and pressing the wire 20. The lower pressing column 17 is docked with the wire pressing part 312. On the basis of the traditional structure, the clamping hole 32 is arranged at the rear end position of the front part of the conductive pin 30. The structure is simple and can be directly manufactured by traditional equipment. The clamping hole 32 can be punched out by further setting a punching knife. In the process of punching the clamping hole 32, the metal material corresponding to the clamping hole 32 can be punched out in a bending manner to abut against the inner side of the cylindrical structure, thereby enhancing the strength of the conductive pin 30.

[0029] See also Figure 6 In the first embodiment of the present invention, a positioning seat 101 is provided on the lower shell 12 at a position corresponding to the conductive pin 30, and the wire pressing portion 31 is positioned and matched with the positioning seat 101, so that the electrical connection between the wire 20 and the conductive pin 30 is more firm and reliable.

There are three conductive pins 30, and all three conductive pins are fixed at the front between the upper shell 11 and the lower shell 12. This structural arrangement can provide sufficient space inside the insulating housing 10 for wiring and can minimize the material cost to the greatest extent. In addition, both the outer surfaces of the upper shell 11 and the lower shell 12 are recessed inwardly with a hand-holding portion 102, which can facilitate grasping the medical connector plug for plugging and unplugging into the medical device.
