Description

Technical Field

[0001] The utility model relates to the technical field of signal transmission spring pins, in particular to an elongated multi-signal transmission spring pin with good contact performance. Background Art

[0002] A spring probe is a precision connector used in electronic products such as mobile phones. The spring probe usually includes a needle shaft, a needle tube and a spring. The spring is arranged in the needle tube, and the needle shaft is inserted in the needle tube. When the needle shaft is squeezed by components, the spring is compressed and moves axially. The outer surface of the needle shaft contacts the inner surface of the needle tube, and the electrical signal is transmitted from the needle shaft to the needle tube.

[0003] The spring probe is connected in the circuit to transmit electrical signals. In order to keep the electrical signal stable during transmission, the needle tube and the needle must always maintain electrical contact, otherwise the electrical signal transmission impedance will increase, and even cause signal interruption.

[0004] Therefore, it is necessary to use an extended multi-signal transmission spring needle with good contact to improve the good contact of the spring needle during the multi-signal data transmission process, so as to facilitate the safe and stable transmission of data.

[0005] For example, the prior art Chinese patent publication number "CN111009763 A" provides an elastic pin contact mechanism, including a needle, a bullet, a needle tube, a spring and a tube cap; the present invention adopts the structure of the bullet and the needle tube, and the present invention arranges an elastic claw and a first convex ridge on the needle tube. The arrangement of the elastic claw is used to solve the problem that when the bullet slides in the needle tube, the elastic claw and the shaft of the bullet always maintain good elastic contact, so as to ensure reliable transmission of information.

[0006] The arrangement of the first convex edge of the device and the groove on the bullet head limits the limit position of the bullet head sliding in the needle tube, and ensures that the bullet head sliding in the needle tube to any limit position will not affect the good contact between the elastic claw and the shaft on the bullet head. The present invention has the advantages of convenient installation, low cost and reliable information transmission.

[0007] In the use of the existing multi-signal transmission spring pin, the extended length of the spring pin is relatively short. When the plug-in position with the external electrical contact structure is deep, the outer end of the spring pin is prone to lose electrical contact with the external structure, and there is a certain gap, which in turn affects the electrical contact connection of the spring pin, resulting in the inability to safely and stably transmit the data signal. The plug-in length of the spring pin cannot be extended, resulting in a poor electrical contact connection between the spring pin and the external structure. Utility Model Content

[0008] The purpose of the utility model is to solve the shortcomings of the prior art that the extension length of the spring pin is short, and when the plug-in position of the plug-in connection with the external electrical contact structure is deep, the outer end of the spring pin is prone to failure to make electrical contact with the external structure, and there is a certain gap, which in turn affects the electrical contact connection of the spring pin, resulting in the inability to transmit data signals safely and stably. An extended multi-signal transmission spring pin with good contact is proposed.

[0009] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0010] An extended multi-signal transmission spring pin with good contact performance is designed, comprising a mounting seat, a plug hole is opened on the surface of the mounting seat, an extension rod passes through the inside of the plug hole, a limit plate is fixed on the surface of the extension rod and at the bottom end of the plug hole, a connecting handle is fixed at the bottom end of the limit plate, an elastic pin groove is opened at the top end of the extension rod and away from the mounting seat, a spring is connected to the inside of the elastic pin groove, the outer end of the spring is connected to a connecting column, and the outer end of the connecting column is equipped with an elastic pin.

[0011] Furthermore, the mounting seat is a rectangular seat structure and is arranged horizontally.

[0012] Furthermore, the five plug holes are evenly distributed on the surface of the mounting base and penetrate the mounting base.

[0013] Furthermore, the extension rod is a circular long rod structure and is vertically arranged and perpendicular to the mounting seat.

[0014] Furthermore, the limiting plate is a circular plate structure and is horizontally arranged at the bottom end of the plug-in hole, and the plug-in hole is a circular hole structure.

[0015] Furthermore, the elastic pin groove is a circular groove structure, and the outer end is open.

[0016] Furthermore, the connecting column is slidably installed inside the elastic pin groove, and the spring is in a compressed state inside the elastic pin groove.

[0017] Furthermore, the elastic pin is a cylindrical structure, and the outer end protrudes from the notch of the elastic pin groove.

[0018] The utility model provides an extended multi-signal transmission spring needle with good contact performance, which has the following beneficial effects:

[0019] 1. The utility model sets a relatively long extension rod, and fixes a limit plate at the bottom end of the extension rod, and fixes a connecting handle at the bottom end of the limit plate. At the same time, a spring pin groove is set at the top end of the extension rod for installing the connecting spring pin. In this way, the use of a relatively long extension rod can facilitate the electrical contact connection between the multi-signal transmission spring pin and the external structure.

[0020] 2. The extension rod of the utility model passes through the plug-in hole and is installed by plugging between the limit plate and the mounting seat. At the same time, the extension rod passes through the longer part of the mounting seat, and the spring pin groove at the top thereof is connected to the spring, and a connecting column is provided at the outer end of the spring, and the spring pin is installed at the outer end of the connecting column and protrudes from the outer end of the extension rod. In this way, the spring pin is installed at the outer end of the extension rod with a longer length, so that the outer end of the spring pin can easily make electrical contact and connection with the external structure without any gap, thereby improving the good electrical contact connection performance of the spring pin and maintaining safe and stable transmission of data signals.
