Description

Technical Field

[0001] The present application relates to the technical field of electrical connectors, and in particular to a plug and socket matching structure. Background Art

[0002] In recent years, with the development of technology, the requirements for power transmission systems have become increasingly higher. To ensure stable electrical connection transmission, plugs and sockets cannot loosen or rotate after being plugged in; to ensure the convenience of installation in extreme environments, plugs and sockets must be able to rotate freely during the plug-in process.

[0003] There are two common structures on the market. One is a freely rotatable plug structure, where the plug can rotate freely relative to the socket, but the above structure can still rotate freely after the plug is fully inserted. During the power-on process, the elastic contact part is prone to failure risk, affecting the reliability of the plug. The other is a keyed plug-in structure, which will not loosen or rotate after being plugged in place, but the angle needs to be adjusted before plugging in. The angle cannot be adjusted during the plugging process. This structure is inconvenient to install and inefficient in compact wiring and harsh environments. Utility Model Content

[0004] The purpose of the present application is to provide a method to solve the defects in the prior art that the plug and socket (connector) structure is unstable after insertion, and the insertion process requires installation at a preset angle, which brings the risk of failure or inconvenience in installation.

[0006] The plug body is provided with an inserting area along the X-axis direction, and at least one first connecting member is fixed in the inserting area;

[0007] A second connector is radially mounted on the outer wall of the socket body, and a plurality of locking areas are circumferentially arranged on the surface of the second connector; the socket body is movably disposed in the plug-in area so that the first connector and the locking area cooperate and lock.

[0008] According to a further solution of the present application, the plug-in area is a first slot provided on the plug body, and the first connecting member is fixed to a bottom of the first slot.

[0010] According to a further solution of the present application, the locking areas are evenly arranged on the second connecting member.

[0011] In a further solution, there are multiple first connecting members, and the spacing between adjacent connecting members is equal and matches the spacing between adjacent locking areas.

[0012] According to a further solution of the present application, a power assist plate is circumferentially sleeved on the socket body.

[0013] According to a further solution of the present application, first guides are provided on both sides of the first connecting member close to one end of the socket body, and a second inclined surface is provided on one end of the locking area close to the plug body, and the inclinations of the first inclined surface and the second inclined surface match.

[0014] Preferably, the locking area is a locking groove provided on the second connecting member, and the first connecting member is a rib; or the locking area is a rib provided on the second connecting member, and the first connecting member is a locking groove.

[0015] In a further solution, the plug body and the socket body are made of insulating material.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] When the present application is used, the plug body is moved toward the socket body so that the second connector enters the plugging area. During the movement, the plug body can rotate freely.

[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use.

[0027] like Figures 1 to 3 As shown, this embodiment discloses a plug-and-socket matching structure, which includes a plug body 1 and a socket body 2 arranged opposite to each other; the plug body 1 is provided with a plug-in area along the X-axis direction, and at least one first connecting member 101 is fixed in the plug-in area; a second connecting member 201 is radially installed on the outer wall of the socket body 2, and a plurality of locking areas 202 are circumferentially provided on the surface of the second connecting member 201; the plug body 1 and the socket body 2 are plugged together so that the first connecting member 201 and the locking area 202 are matched and locked.

[0028] When in use, insert one end of the second connecting piece 201 on the socket body 2 into the plugging area on the plug body 1. Since there are multiple locking areas 202 on the second connecting piece 201, the first connecting piece 101 and the locking area 202 can cooperate at multiple angles to fix the plug body 1 and the socket body 2. The device is easy to install, and after installation, the socket body 2 and the plug body 1 cannot be twisted relative to each other, thereby ensuring connection efficiency while improving safety.

[0029] Reference Figure 3, it can be seen that the specific structure of the plug-in area in this embodiment is that the plug-in area is a first slot 100 arranged on the plug body 1, and the first connecting member 101 is fixed at the bottom of the first slot 10. The installation position of the first connecting member 101 is relatively deep, so that the contact area between the plug body 1 and the socket body 2 is larger, which can improve the connection stability; in addition, this embodiment also arranges a guide tube 102 on the head body 1 along the X-axis direction, and the first connecting member 101 is fixed on the bottom of the first slot 100 outside the wall of the guide tube 102; a second slot 200 is axially arranged on the socket body 2, and the guide tube 102 is movably placed in the second slot 200; during the connection process between the plug body 1 and the socket body 2, the guide tube 102 moves in contact with the side wall of the second slot 200, and has a certain guiding function.

[0030] Reference Figure 5 and 4 In this embodiment, the first connecting member 101 and the locking area 202 are optimized. The first connecting member 101 is provided with a first inclined surface on both sides of one end close to the socket body 2, and the locking area 202 is provided with a second inclined surface at one end close to the plug body 1. The inclinations of the first inclined surface and the second inclined surface match. In this way, the first connecting member 101 and the locking area 202 are contacted and extruded and guided by the first inclined surface and the second inclined surface during the connection process, so that connection at any angle can be achieved, and the installation efficiency of the plug body 1 and the socket body 2 is further improved.

[0031] Preferably, the locking area 202 is a locking groove provided on the second connecting member 201, the first connecting member 101 is a rib, and the plug body 1 and the socket body 2 are covered with insulating glue to improve safety.

[0032] Preferably, when the device is installed with multiple first connecting members 101, the spacing between adjacent connecting members 101 is designed to be equal and match the spacing between adjacent locking areas 202; in order to facilitate the user to apply force, a power assist plate 203 is circumferentially sleeved on the socket body 2.

[0033] In some other embodiments, the plug body 1 and the socket body 2 are limited in the X direction after the plugging is completed to prevent the plug body 1 and the socket body 2 from separating. Figure 6 Specifically, an elastic limiting member 103 is installed on the outer wall of the plug body 1, and a plurality of limiting holes 204 are equidistantly arranged on the outer wall of the socket body 2. After the plug body 1 and the socket body 2 are plugged in, one end of the limiting member 103 will enter the limiting hole 204 to limit the plug body 1 and the socket body 2 in the X-axis direction.

[0034] Specific use:

[0035] The user holds the plug body 1 in one hand and the socket body 2 in the other hand, and the two hands move toward each other, or the socket body 2 is fixedly installed on the mounting plate, and the user holds the plug body 1 and moves it toward the socket body 2; the second connecting member 201 is placed in the area between the outer wall of the guide tube 102 and the side wall of the first slot 100, and before the locking area 202 (locking groove) and the first connecting member 101 (rib) are not in contact, the radial relative positions of the plug body 1 and the handheld socket body 2 can be changed arbitrarily until the locking groove and the rib are in contact, and one end of the limiting member 103 enters the limiting hole 20, completing the plug-in installation of the plug body 1 and the socket body 2. For the installation effect, refer to the attached Figure 6 .

[0036] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
