A connector for a retractable data cable and a small-volume electrical connection structure thereon.

Abstract

This utility model discloses a connector for a retractable data cable and a small-volume electrical connection structure thereof, including a housing and PIN pins. The housing has multiple spaced slots. The PIN pins include an integrally formed solder foot, an insert extending into the side wall of the housing, and a contact portion extending from the insert into the slot. The bottom wall of the solder foot extends out of the lower wall of the housing. The contact portion includes a first bend bending upward from the side wall of the housing and a second bend extending into the slot from the first bend. There is a gap between the end of the second bend and the wall of the slot. A contact end is formed between the first bend and the second bend, and the contact end extends out of the upper wall of the housing. The integrally formed PIN pins can effectively ensure structural rigidity. The front end of the second bend is suspended, so the contact end has a larger range of motion. The first bend extends directly from the housing, so it can provide a relatively stable upward support force, thereby ensuring that the contact end can have a predetermined contact force with the conductive layer.

Description

Technical Field

[0001] This utility model relates to the field of retractable data cables, and in particular to a connector for a retractable data cable and a small-volume electrical connection structure having the same. Background Technology

[0002] Existing retractable data cables generally consist of a moving plate and a fixed plate. The moving plate and the fixed plate are respectively equipped with a conductive layer and a spring. In order to ensure stable cooperation between the two, the current practice is to use a spring with greater elasticity to ensure electrical conduction.

[0003] For example, Chinese patent 202222905924.9 uses a multi-bend structure for its contact pin to ensure its elasticity and contact force. However, in actual practice, it also causes significant wear on the conductive layer. The current approach is generally to increase the thickness of the conductive layer, which in turn increases the thickness of the moving and fixed plates. Summary of the Invention

[0004] The main purpose of this utility model is to propose a connector for a retractable data cable and a small-volume electrical connection structure thereon, which aims to improve the existing connector structure, ensuring good spring elasticity, providing a more stable contact force, and having a smaller thickness for easy installation.

[0005] To achieve the above objectives, this utility model proposes a connector for a retractable data cable, comprising:

[0006] The housing has multiple spaced slots.

[0007] The PIN pin includes an integrally formed solder foot, an insert portion extending into the side wall of the housing, and a contact portion extending into a slot from the insert portion.

[0008] The bottom wall of the weld foot extends out of the lower wall of the housing;

[0009] The contact portion includes a first bend that bends upward from the side wall of the housing and a second bend that extends from the first bend toward the groove, wherein there is a gap between the end of the second bend and the wall of the groove.

[0010] A contact end is formed between the first bend and the second bend, and the contact end extends out of the upper wall of the housing.

[0011] In the actual design, a simple PIN structure is adopted, which can effectively reduce the overall thickness of the shell. The one-piece molded PIN can effectively ensure the structural rigidity. The front end of the second bend is suspended, so the contact end has a larger range of motion. The first bend extends directly from the shell, so it can provide a relatively stable upward support force, thereby ensuring that the contact end can have the predetermined contact force with the conductive layer.

[0012] A small-volume electrical connection structure, characterized in that it includes a PCB board and a connector for the aforementioned telescopic data cable disposed on the PCB board.

[0013] The solder feet are fixed to the PCB board via overcurrent soldering. The overall thickness of the housing is relatively small, and it is directly fixed using a surface mount method, which effectively reduces the thickness and difficulty of soldering the PCB board.

[0030] like Figures 1 to 7 As shown, a connector for a retractable data cable includes,

[0031] The housing 1 is provided with a plurality of spaced slots 11;

[0032] PIN pin 2, the PIN pin 2 includes an integrally formed solder foot 21, an insert portion 22 extending from the solder foot 21 into the side wall of the housing 1, and a contact portion 25 extending from the insert portion 22 into the groove 11.

[0033] The welding foot 21 extends out of the lower wall of the housing 1;

[0034] The contact portion 25 includes a first bent portion 23 that bends upward from the side wall of the housing 1 and a second bent portion 24 that extends from the first bent portion 23 toward the groove 11. A gap is provided between the end of the second bent portion 24 and the wall of the groove 11.

[0035] A contact end is formed between the first bent portion 23 and the second bent portion 24, and the contact end extends out of the upper wall of the housing 1.

[0036] In the actual design, a simple PIN structure is adopted, which can effectively reduce the overall thickness of the housing 1. The one-piece molded PIN pin 2 can effectively ensure the structural rigidity. The front end of the second bending part 24 is suspended, so the contact end has a larger range of motion. The first bending part 23 extends directly from the housing 1, so it can provide a relatively stable upward support force, thereby ensuring that the contact end can have the predetermined contact force with the conductive layer.

[0037] The first embodiment is more suitable for small-scale production, while the second embodiment is more suitable for standardized large-scale production. The shell thickness of the first embodiment is smaller, while the shell thickness of the second embodiment is larger.

[0038] Specifically, the slot 11 is a through slot or groove. In actual design, a through slot is preferred, thereby reducing the thickness of the plastic.

[0039] In this embodiment of the utility model, when it is a through groove, a strip portion 12 is provided between adjacent through grooves, thereby dividing adjacent PIN pins 2 to ensure the insulation and guiding function of adjacent PIN pins.

[0040] Specifically, the welding foot 21 and the embedded part 22 are horizontally arranged, which facilitates injection molding and also avoids the increase in thickness of the shell 1 caused by the bending structure.

[0041] In this embodiment of the utility model, the first bending portion 23 extends from the bottom or middle of the inner wall of the groove 11; the first bending portion 23 extends obliquely or arc-shaped, and through reasonable position distribution, it can ensure the plastic coating while providing a predetermined support and reducing the thickness of the shell 1.

[0042] Specifically, the front wall of the slot 11 is provided with an inclined surface, and the first bent part 23 abuts against or is embedded in the inclined surface. The embedding can be partial embedding, complete embedding, or exposed setting, so it can play a role in limiting the upward swing range of the PIN pin 2.

[0043] In this embodiment of the utility model, the bottom wall of the housing 1 is provided with at least two positioning posts 3, which facilitates the installation of the housing 1 on the PCB board 4, and provides accurate positioning and limiting, thereby reducing the stress on the solder feet 21.

[0044] The upper wall of the housing is provided with a cutting groove, which is located between adjacent PIN pins.

[0045] Specifically, the upper wall of the housing 1 is provided with a contact portion 25, which is located between adjacent PIN pins 2. In the actual design, the PIN pins 2 are conveyed and injected as a whole through the sheet material; however, the adjacent PIN pins 2 are prone to swinging. Therefore, a connecting portion is provided between the adjacent PIN pins 2, so that the adjacent PIN pins 2 can be separated through the contact portion 25 after injection molding is completed.

[0046] A small-volume electrical connection structure includes a PCB board 4 and a connector for the aforementioned retractable data cable disposed on the PCB board 4.

[0047] The solder feet 21 are fixed to the PCB board 4 by overcurrent soldering. The overall thickness of the housing 1 is relatively small, and it is directly fixed by surface mount technology, which can effectively reduce the soldering thickness and difficulty of the PCB board 4.

[0048] Specifically, the PCB board 4 has a through hole 5 in the middle, and the diameter of the PCB board 4 is compatible with the diameter of the housing 1. In actual design, the minimum thickness of the housing 1 can reach 1.2mm, and the minimum thickness of the housing 1 can reach 3.0mm (excluding the positioning post part). The minimum diameter of the PCB board 4 can reach 12mm, which is much smaller than the size of existing designs.

[0049] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
