Limiting structure for male and female plug-in of connector

Abstract

According to the limiting structure for male and female plug-in of the connector provided by the invention, when the power-assisted rod locks the plug assembly and the socket assembly, the limiting block limits the left-right movement of the power-assisted rod, so that the connection strength of the socket assembly and the plug assembly is prevented from being influenced; when the plug assembly and the socket assembly are locked by the assistance rod, two oppositely distributed second bulges on the annular grooves at the left side and the right side are respectively clamped with a first clamping column and a second clamping column, so that the male and the female are prevented from falling off during vibration after being inserted; when the power-assisted rod unlocks the plug assembly and the socket assembly, the first protrusion abuts against the limiting block on the power-assisted rod, and the situation that the power-assisted rod is pulled excessively is avoided. When the power assisting rod unlocks the plug assembly and the socket assembly, the limiting pin on the power assisting rod rotates with the first clamping column as the axis, and the purpose of helping the power assisting rod reset is achieved.

Description

Technical Field

[0001] The invention belongs to the technical field of plugs and sockets, and in particular relates to a limiting structure for plugging male and female connectors. Background Art

[0002] As a convenient connection component, connectors have been widely used in various industries, such as the new energy vehicle industry. Due to different usage environments, there will be various requirements for the outlet direction of the connector. In order to improve versatility and reduce investment costs, socket sharing is usually selected. The plug has a variety of outlet angles, so the plug has different structures such as straight and curved. When the plug and socket are connected and fixed, in order to facilitate the connection between the two, a rotatable power lever is often provided on the plug. By controlling the power lever, the two are tightly connected and not easy to fall off.

[0003] However, when the plug and the socket are locked by means of a rotatable power lever, the power lever often lacks a limiting mechanism, which causes the power lever to shake under the action of the turn pin during use, thereby affecting the connection strength of the plug and the socket; the lack of a limiting structure in the process of pulling the power lever can easily cause the power lever to be pulled too far; the lack of a limiting structure when the power lever locks the plug and the socket can easily cause the plug and the socket to vibrate and fall off; therefore, the present invention proposes a limiting structure for male and female connectors to solve the above problems. Summary of the invention

[0004] The invention provides a plug-in limiting structure for a male and female connector, aiming to solve the problems raised by the background technology.

[0005] The present invention is implemented as follows: a male-female connector plug-in limiting structure comprises a plug assembly, a power lever and a socket assembly, wherein the plug assembly comprises a plug housing, an outer wall of the plug housing is provided with two first rotating pins and a second rotating pin which are relatively distributed, the power lever is rotatably connected with the first rotating pin and the second rotating pin, the plug housing is provided with a first card slot and a second card slot, and a first protrusion is provided on the inner wall of the first card slot;

[0006] A limit block and a limit pin are provided on the inner side of the booster rod, the limit block and the limit pin are relatively distributed, the limit block is a triangular structure, the limit block is rotatably connected to the slot, the booster rod includes an annular groove, and two relatively distributed second protrusions are provided on the annular groove;

[0007] The socket assembly includes a socket shell, on which a first engaging column and a second engaging column are provided. The first engaging column is engaged with the first engaging slot, the second engaging column is engaged with the second engaging slot, the first engaging column and the second engaging column are rotatably connected to the annular groove, and the limit pin is rotatably connected to the first engaging column.

[0008] Preferably, the first rotating pin and the second rotating pin are coaxial.

[0009] Preferably, the power assist rod rotates around the first rotating pin and the second rotating pin as an axis.

[0010] Preferably, the plug assembly is snap-connected with the socket assembly.

[0011] Preferably, when the power-assisting rod locks the plug assembly and the socket assembly, the limit block restricts the power-assisting rod from moving up and down.

[0012] Preferably, when the power-assisting rod unlocks the plug assembly and the socket assembly, the limiting pin on the power-assisting rod rotates around the first engaging column as an axis, thereby helping the power-assisting rod to reset.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. When the power lever locks the plug assembly and the socket assembly, the limit block restricts the left and right movement of the power lever to avoid affecting the connection strength between the socket assembly and the plug assembly; when the power lever locks the plug assembly and the socket assembly, the two relatively distributed second protrusions on the annular grooves on the left and right sides are respectively engaged with the first engaging column and the second engaging column to prevent the male and female from falling off when vibrating after being plugged in;

[0015] 2. When the power-assisting rod unlocks the plug assembly and the socket assembly, the first protrusion conflicts with the limit block on the power-assisting rod to prevent the power-assisting rod from being over-moved; when the power-assisting rod unlocks the plug assembly and the socket assembly, the limit pin on the power-assisting rod rotates around the first engaging column as the axis to help the power-assisting rod reset.

[0033] In this embodiment, the power-assisting rod 2 is engaged with the first rotating pin 12 and the second rotating pin 13 in the plug assembly 1, and then the socket assembly 3 is engaged with the plug assembly 1. At this time, the annular groove 23 in the power-assisting rod 2 is engaged with the first engaging column 32 and the second engaging column 33, and the first engaging column 32 and the second engaging column 33 fall into the inside of the engaging groove 14 and the engaging groove 2 15 respectively. The power-assisting rod 2 is held and rotated 90° (optimal rotation angle). At this time, the power-assisting rod 2 locks the socket assembly 3 with the plug assembly 1. A semicircular groove is provided at the front end of the power-assisting rod 2, and a spring-connected ball is provided on the plug assembly 1. At this time, the ball is stuck in the semicircular groove to achieve locking;

[0034] When the booster rod 2 locks the plug assembly 1 and the socket assembly 3, the limit block 21 limits the left and right movement of the booster rod 2 to avoid affecting the connection strength between the socket assembly 3 and the plug assembly 1;

[0035] When the power lever 2 locks the plug assembly 1 and the socket assembly 3, refer to the attached Figure 6 and attached Figure 7At this time, the two relatively distributed second protrusions 24 on the annular grooves 23 on the left and right sides are respectively engaged with the first engaging column 32 and the second engaging column 33 to prevent the male and female from falling off when vibrating after being plugged in;

[0036] When the power lever 2 unlocks the plug assembly 1 and the socket assembly 3, refer to the attached Figure 3 At this time, the first protrusion 16 and the limit block 21 on the power lever 2 are in conflict with each other, so as to prevent the power lever 2 from being over-moved.

[0037] When the power-assisting rod 2 unlocks the plug assembly 1 and the socket assembly 3 , the limiting pin 22 on the power-assisting rod 2 rotates around the first engaging column 32 , thereby helping the power-assisting rod 2 to reset.

[0038] Furthermore, the first rotating pin 12 and the second rotating pin 13 are coaxial.

[0039] For further information, see Figure 3 , Figure 4 and Figure 6 The power lever 2 rotates around the first rotating pin 12 and the second rotating pin 13 as an axis.

[0040] In this embodiment, since the first rotating pin 12 and the second rotating pin 13 are coaxial, the assisting rod 2 can be rotated around the first rotating pin 12 and the second rotating pin 13 by gripping the assisting rod 2 .

[0041] For further information, see Figure 7 , the plug assembly 1 is snap-connected with the socket assembly 3.

[0045] Furthermore, when the power-assisting rod 2 unlocks the plug assembly 1 and the socket assembly 3 , the limiting pin 22 on the power-assisting rod 2 rotates around the first engaging column 32 , thereby helping the power-assisting rod 2 to reset.

[0046] In this embodiment, see the attached Figure 4 FIG. 2 is a state diagram of the stop pin 22 after the booster rod 2 unlocks the plug assembly 1 and the socket assembly 3. When the booster rod 2 locks the plug assembly 1 and the socket assembly 3, the stop pin 22 rotates 90° clockwise (compared to the attached Figure 4 ), and the limit pin 22 always rotates along the outer wall of the first engaging column 32. Therefore, the limit pin 22 on the power-assisting rod 2 rotates around the first engaging column 32, which helps the power-assisting rod 2 to reset so that the power-assisting rod 2 will not deviate from its position.

[0047] The working principle and use process of the present invention are as follows: the power-assisting rod 2 is clamped with the first rotating pin 12 and the second rotating pin 13 in the plug assembly 1, and then the socket assembly 3 is clamped with the plug assembly 1.

The power-assisting rod 2 is held and rotated 90° (optimal rotation angle). At this time, the power-assisting rod 2 locks the socket assembly 3 with the plug assembly 1. A semicircular groove is provided at the front end of the power-assisting rod 2, and a spring-connected ball is provided on the plug assembly 1. At this time, the ball is clamped in the semicircular groove to achieve locking; when the power-assisting rod 2 locks the plug assembly 1 and the socket assembly 3, the limit block 21 limits the power-assisting rod 2 from moving left and right to avoid affecting the connection strength of the socket assembly 3 and the plug assembly 1; when the power-assisting rod 2 locks the plug assembly 1 and the socket assembly 3, refer to the attached Figure 6 and attached Figure 7 At this time, the two second protrusions 24 on the annular grooves 23 on the left and right sides are respectively engaged with the first engaging column 32 and the second engaging column 33 to prevent the male and female from falling off when vibrating after being plugged in; when the power lever 2 unlocks the plug assembly 1 and the socket assembly 3, refer to the attached Figure 3 At this time, the first protrusion 16 conflicts with the limit block 21 on the power-assisting rod 2 to prevent the power-assisting rod 2 from being moved too far; when the power-assisting rod 2 unlocks the plug assembly 1 and the socket assembly 3, the limit pin 22 on the power-assisting rod 2 rotates around the first engaging column 32 to help the power-assisting rod 2 return to its original position.
