Description

Technical Field

[0001] The present invention relates to an electrical connector, and in particular to a grounding shielding component for a connector. Based on this, the present invention also relates to a connector and a connector system comprising the grounding shielding component. Background Art

[0002] Electrical connectors are widely used in various electronic devices, mainly for signal transmission and power transmission between devices. In electronic devices, it is sometimes necessary to limit the influence of power lines or magnetic lines to a certain range, and to prevent the influence of external electrostatic induction or electromagnetic induction within a given space. In this case, a container made of low-resistance materials or magnetic materials such as copper or aluminum is used to wrap all the parts that need to be isolated.

[0003] Typically, in a circular connector, a male connector (plug) can be plugged into a female connector (socket), and their respective grounding shielding components are arranged to surround the conductive pins and radially contact each other in the plugged-in state. Such grounding shielding components are usually metal components and can be configured to have a metal cantilever or stamping structure, and the grounding connection is achieved through a spring clamp provided on the socket. However, this radial contact grounding shielding connection structure requires more radial space in the housing to be suitable for installing such components. In addition, the socket is often assembled on the user equipment panel, and the clamping ring and groove used to keep the grounding shielding component reliably engaged will affect the appearance of the equipment.

[0004] In view of this, it is necessary to provide a new ground shielding component to meet the development requirements of miniaturization and aesthetics of electrical connectors. Summary of the invention

[0005] The purpose of the present invention is to overcome the problem in the prior art that there is no more space in the electrical connector to install the grounding shielding component, and to provide a grounding shielding component for the connector. When the connector is inserted, the grounding shielding component is suitable for abutting against another grounding shielding component along the insertion direction of the connector to avoid additionally occupying radial space in the shell, thereby facilitating reducing the size of the connector.

[0006] In order to achieve the above-mentioned objectives, on one hand, the present invention provides a grounding shielding component for a connector, the grounding shielding component having a side wall for being arranged to surround a first conductive pin, the side wall having a first end for abutting against another grounding shielding component of a socket along an insertion direction of the connector and a second end opposite to the first end, and the side wall is configured to be able to elastically deform in the insertion direction so that the first end elastically abuts against the other grounding shielding component when the connector is electrically connected to the socket.

[0007] Preferably, the side wall of the ground shielding component has a circular cross-section.

[0008] Preferably, a spiral groove spirally extending around the central axis of the grounding shielding component is formed on the side wall of the grounding shielding component, so that the side wall can be elastically deformed in the axial direction and can abut against the other grounding shielding component of the socket in the axial direction.

[0009] Preferably, one end of the spiral groove is open at the first end to allow the spiral groove to be machined from the first end.

[0010] Preferably, a surface of the first end extends in a plane perpendicular to an axial direction of the ground shielding component.

[0011] Preferably, the side wall of the ground shielding component is formed with an abutment portion adjacent to the second end and protruding radially outward.

[0012] Preferably, the grounding shielding component is an integrally formed part made of metal material.

[0013] Preferably, the grounding shielding component is made of stainless steel or copper alloy.

[0014] A second aspect of the present invention provides a connector, comprising a connector housing, a first conductive pin, and the above-mentioned ground shielding component arranged in an annular space between the first conductive pin and the connector housing.

[0015] A third aspect of the present invention provides a connector system, comprising:

[0016] A connector, comprising a connector housing, a first conductive pin, and a ground shielding component arranged in an annular space between the first conductive pin and the connector housing, wherein the connector housing has a first clamping portion;

[0017] A socket, comprising a socket housing, a second conductive pin, and the other grounding shielding component arranged in an annular space between the second conductive pin and the socket housing, wherein the socket housing has a second clamping portion;

[0018] In which, at least one of the grounding shielding component and the other grounding shielding component is configured to be able to elastically deform in the insertion direction of the connector, and when the connector is plugged into the socket and the first clamping portion is engaged with the second clamping portion, the opposite ends of the grounding shielding component and the other grounding shielding component elastically abut against each other along the plug-in direction.

[0019] Through the above technical scheme, the grounding shielding component of the present invention can be elastically deformed in the insertion direction of the connector, so that one end (i.e., the first end) in the insertion direction can reliably abut against another grounding shielding component of the socket when the connector is inserted, thereby ensuring the shielding effect against external electrostatic induction or electromagnetic induction force. Since the grounding shielding connection is realized in the insertion direction of the connector through its end, the occupation of the radial space in the shell can be effectively reduced, and there is no need to set components or structures such as retaining rings and grooves, which is convenient for reducing the size of the connector and improving the aesthetics of the electrical connector system. Compared with the radial contact method in the conventional technology, the grounding shielding component of the present invention elastically deforms along the insertion direction of the connector and utilizes the first end in the insertion direction to abut against another grounding shielding component of the socket, so that it can still maintain good contact after long-term use, and thus has a high plug-in life.

[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] Figure 1 and Figure 2A connector system is shown, which includes a connector 1 and a socket 2, wherein the connector 1 is set as a male connector and is usually connected to the end of a cable to be used as a plug; the socket 2 is set as a female connector and is usually assembled on the panel of an electronic device. When in use, the connector 1 can be plugged into the socket 2 to achieve signal transmission and power transmission between devices.

[0028] More specifically, the connector 1 includes a connector housing 11, a plurality of first conductive pins 14 extending in the connector housing 11, and a ground shielding component 12 arranged in the connector housing 11 and surrounding the first conductive pins 14. The plurality of first conductive pins 14 may be separated from each other by a first insulating component 13, and electrically connected at one end to a cable (not shown) axially limited by, for example, a cable clamp 15. The ground shielding component 12 surrounds the first conductive pins 14 to shield the external power lines or magnetic lines of force during the transmission of signals or electrical energy through the first conductive pins 14, thereby preventing the influence of electrostatic induction or electromagnetic induction forces on the connection position.

[0029] The socket 2 includes a socket housing 21, a plurality of second conductive pins 24 extending in the socket housing 21, and another ground shielding component 22 arranged in the socket housing 21 and surrounding the second conductive pins 24. The plurality of second conductive pins 24 can be separated from each other by a second insulating component 23, one end of which can be electrically connected to an electronic device such as an electronic device, and the other end can be in contact with the first conductive pin 14 when the connector 1 is plugged into the socket 2. The other ground shielding component 22 surrounds the second conductive pin 24 to shield the external power lines or magnetic lines of force during the transmission of signals or electrical energy through the second conductive pin 24, thereby preventing the influence of electrostatic induction or electromagnetic induction on the connection position.

[0030] In order to keep the connector 1 and the socket 2 in a plugged state at a position where the first conductive pin 14 contacts the second conductive pin 24 and prevent the connector 1 from accidentally falling off the socket 2, the connector housing 11 and the socket housing 21 may be provided with a plug-in retaining structure at the position where they are plugged into each other. For example, a first clamping portion 11a in the form of a clamping ring may be provided on the outer circumference of the connector housing 11, and a second clamping portion 21a in the form of a clamping groove for matching with the first clamping portion 11a may be formed on the inner circumference of the socket housing 21. When the connector 1 is plugged into the socket 2 and the first clamping portion 11a matches with the second clamping portion 21a, the first conductive pin 14 of the connector 1 and the second conductive pin 24 of the socket 2 are in contact with each other to transmit signals or electrical energy.

[0031] Since the signal or electric energy needs to be transmitted between the first conductive pin 14 of the connector 1 and the second conductive pin 24 of the socket 2, it is necessary to shield the electric power lines or magnetic lines from the outside within the entire extended length of the first conductive pin 14 and the second conductive pin 24 including the contact point. In this case, in the plugged state, the ground shielding component 12 of the connector 1 should be connected to the other ground shielding component 22 of the socket 2 to ensure the ground shielding effect. In the prior art, as mentioned above, the ground shielding components of the connector and the socket are arranged to be in radial contact with each other, thereby occupying more radial space of the shell, which is not conducive to the miniaturization of the electrical connector system, and it is necessary to set a snap ring and a groove similar to the above-mentioned first snap-in portion 11a and the second snap-in portion 21a on the shell, which affects the aesthetics of the electronic device.

[0032] To this end, the present invention provides a new ground shielding component 12, such as Figure 3 As shown in FIG. 1 , the ground shielding component 12 has a side wall arranged to surround the first conductive pin 14. Figure 1 and Figure 2 In the connector system shown, the connector 1 is a circular connector, so the side wall of the ground shielding component 12 has a circular cross-section, that is, it is formed as a circumferential wall. The side wall has a first end 121 and a second end 122 opposite to the first end 121, and the first end 121 can be used to abut against another contact shielding component 22 of the socket 2 along the insertion direction (such as the axial direction) of the connector 1.

[0033] The side wall of the ground shielding component 12 is configured to be elastically deformable in the insertion direction (such as the axial direction) of the connector 1. When the connector 1 is electrically connected to the socket 2, the side wall of the ground shielding component 12 is compressed in the insertion direction (such as the axial direction) of the connector 1 to elastically abut against the other contact shielding component 22. Thus, the connector 1 having the ground shielding component 12 can be used in a connection area with limited radial space for grounding.

[0034] Through the above arrangement, the ground shielding component 12 of the present invention can be elastically deformed in the insertion direction (such as axial direction) of the connector 1, so that one end (i.e., the first end 121) in the length direction can reliably abut against another ground shielding component 22 of the socket 2 when the connector 1 is inserted, thereby ensuring the shielding effect against external electrostatic induction or electromagnetic induction force. Since the ground shielding connection is realized in the insertion direction of the connector 1 through its end, the radial space occupied in the shell can be effectively reduced, and there is no need to set components or structures such as snap rings and grooves, which is convenient for reducing the size of the connector and improving the aesthetics of the electrical connector system.

[0035] In addition, for the conventional radial contact grounding shielding component, it is easy to cause poor contact due to wear and other problems after long-term use, and the plug-in life is short. The grounding shielding component 12 of the present invention uses its first end 121 in the length direction to abut against another grounding shielding component 22 of the socket through elastic deformation along the insertion direction of the connector 1, and can still maintain good contact after long-term use, so it has a long plug-in life.

[0036] It should be noted that, although the ground shielding component used in a circular connector will be mainly used as an example for explanation here and below, and its length direction is therefore the axial direction, when the ground shielding component is used in a non-circular connector, its side wall may have a cross-sectional shape other than a circular cross-sectional shape. Therefore, the direction in which the connector is plugged into the socket is collectively referred to as the "length direction", and when the connector is a circular connector, the length direction is the axial direction.

[0037] The side wall of the ground shielding component 12 can be configured to be elastically deformable in the axial direction in a variety of suitable ways. For example, the elastic deformation can be configured so that the force generated by the elastic deformation can be calculated and adjusted. Figure 3 As shown, a spiral groove 123 extending spirally around the central axis can be formed on the side wall of the ground shielding component 12, so that when it abuts against another ground shielding component 12 of the socket 2, the part of the side wall provided with the spiral groove 123 is squeezed, and the width of the spiral groove 123 is reduced; when it is out of contact with the other ground shielding component 12 of the socket 2, the part of the side wall provided with the spiral groove 123 is reset to the initial state, so that it can be elastically deformed in the axial direction. Through this arrangement, the ground shielding component 12 can move smoothly and reliably abut against another ground shielding component 12 of the socket 2, and can ensure a relatively long service life.

[0038] The above-mentioned spiral groove 123 can be directly machined on the side wall of the ground shielding component 12, that is, formed into a spring-like structure, so that it can axially contact and elastically abut against the other ground shielding component 12 of the socket 2. In order to facilitate the above-mentioned spring-like structure to be obtained by machining on a cylindrical workpiece, cutting can be performed from the axial end of the workpiece, so that one end of the spiral groove 123 is open at the first end 121 or the second end 122. In the illustrated embodiment, the spiral groove 123 is open at the first end 121, which allows the spiral groove 123 to be machined from the first end 121 and abut against the other ground shielding component 22 of the socket 2 through the spiral end. In other embodiments, the spiral groove 123 can also be formed in the middle position of the length direction of the side wall of the ground shielding component 12, and can also be elastically abutted against the other ground shielding component 22 of the socket 2 by using its end.

[0039] Furthermore, the surface of the first end 121 may be arranged to extend in a plane perpendicular to the axial direction of the ground shielding component 12 , thereby being able to reliably abut against an end surface of another ground shielding component 12 of the socket 2 along the axial direction.

[0040] At the second end 122 of the ground shielding component 12 , a side wall thereof may be formed with an abutting portion 124 protruding radially outward, so that the axial position of the ground shielding component 12 can be limited by the second end 122 abutting against, for example, a cable clamp 15 .

[0041] In the present invention, the provided ground shielding component 12 is preferably an integrally formed part made of metal material, so that no additional clamping ring or other spring structure for connection is required. More preferably, the metal material can be stainless steel or copper alloy.

[0042] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any suitable manner. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
