Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a foolproof rotary electrical connector. Background Technology

[0002] With changing market demands, modern connectors need to be designed to integrate anti-misfit mechanisms to ensure that after correct mating, they can be flexibly adjusted to match the internal cable layout of the chassis and rotate 360° as the cable layout changes. However, current electrical connectors cannot achieve 360° rotation under the premise of preventing mistaken insertion. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a foolproof rotary electrical connector that simultaneously meets the requirements of foolproof installation and 360° rotation.

[0004] The purpose of this utility model is achieved through the following technical solution: a foolproof rotary electrical connector, comprising a plug and a socket for mating, the socket comprising a key mounting plate and a plug housing, one end of the plug housing having a mating groove, a connecting post fixed in the mating groove, the key mounting plate being slidably mounted on the side wall of the plug housing, the plug comprising a socket housing and a mating post, the mating post being adapted to the mating groove, the connecting post being inserted into the mating post, the side wall of the mating post having multiple convex key blocks fixed, the multiple convex key blocks being evenly distributed along the circumference of the mating post, a foolproof mating space being formed between two adjacent convex key blocks, the side wall of the mating post forming a cylindrical surface behind the convex key blocks, the inner wall of the key mounting plate having multiple foolproof key blocks fixed, the foolproof key blocks being located in the mating groove, when the plug and socket are mated, the foolproof key blocks pass through the foolproof mating space and contact the cylindrical surface.

[0005] Furthermore, the key mounting plate has an arc-shaped groove at one end near the plug housing, and the plug housing is inserted into the arc-shaped groove.

[0006] Furthermore, an undercut is fixed inside the arc-shaped groove, the undercut is elastic, and an arc-shaped sliding groove is provided on the side wall of the plug housing, the undercut being interference-fitted into the arc-shaped sliding groove.

[0007] Furthermore, a locking mechanism is provided on one side of the plug housing. The locking mechanism includes a latch. A locking groove is provided on the side of the plug housing. The locking groove communicates with the insertion groove. The latch is slidably disposed in the locking groove and is located on the moving path of the convex key block.

[0008] Furthermore, a spring is connected inside the locking groove, the spring is connected to the latch, the top surface of the latch has an arc-shaped opening for the convex key block to pass through, the end face of the latch near the plug has an inclined surface, and the end face of the latch away from the plug is a flat surface. When the spring is in its normal state, the inclined surface is located on the moving path of the convex key block.

[0009] The beneficial effects of this utility model are:

[0010] The plug and socket can only be connected after the key block corresponds to the key block space. It has the effect of preventing mistakes. After the plug and socket are connected, the key block contacts the cylindrical surface, allowing the socket and plug to rotate 360°, which facilitates cable layout. Attached Figure Description

Detailed Implementation

[0017] Example 1

[0018] like Figures 1 to 5As shown, a foolproof rotary electrical connector includes a plug 1 and a socket 2 for mating. The socket 2 includes a key mounting plate 2-1 and a plug housing 2-2. One end of the plug housing 2-2 has a mating groove, and a connecting post 2-5 is fixed in the mating groove. The key mounting plate 2-1 is slidably mounted on the side wall of the plug housing 2-2. The plug 1 includes a socket housing and a plug post 1-3. The plug post 1-3 is fixed on the socket housing and fits into the mating groove. The connecting post 2-5 is inserted into the plug post 1-3. Multiple convex key blocks 1-1 are fixed on the side wall of the plug post 1-3. The multiple convex key blocks 1-1 are evenly distributed along the circumference of the plug post 1-3. A foolproof mating space 1-4 is formed between two adjacent convex key blocks 1-1. A cylindrical surface 1-2 is formed on the side wall of the plug post 1-3 behind the convex key blocks 1-1. Multiple foolproof key blocks 2-1-1 are fixed on the inner wall of the key mounting plate 2-1. The foolproof key blocks 2-1-1 are located in the plug slot. When the plug 1 is plugged into the socket 2, the foolproof key block 2-1-1 passes through the foolproof plug space 1-4 and contacts the cylindrical surface 1-2. When connecting the plug 1 and the socket 2, the plug post 1-3 is inserted into the plug slot, and the connecting post 2-5 is inserted into the plug post 1-3. During the plugging process, the foolproof key block 2-1-1 needs to be aligned with the foolproof plug space 1-4 to complete the connection between the plug 1 and the socket 2, which has a foolproof effect. When the plug 1 and the socket 2 are connected in place, the foolproof key block 2-1-1 passes through the foolproof plug space 1-4 and contacts the cylindrical surface 1-2. At this time, the plug 1 and the socket 2 can rotate 360°, which can be flexibly adjusted according to the cable layout inside the chassis.

[0019] Example 2

[0020] Based on Example 1, such as Figures 1 to 5 As shown, the key mounting plate 2-1 has an arc-shaped groove 2-7 at one end near the plug housing 2-2. The plug housing 2-2 is inserted into the arc-shaped groove 2-7. An undercut 2-1-2 is fixed in the arc-shaped groove 2-7. The undercut 2-1-2 is elastic. An arc-shaped sliding groove 2-1-3 is provided on the side wall of the plug housing 2-2. The undercut 2-1-2 is interference-fitted in the arc-shaped sliding groove 2-1-3, so that the key mounting plate 2-1 can slide on the plug housing 2-2 to adjust the insertion and removal direction.

[0021] Example 3

[0022] Based on Example 2, such as Figures 1 to 3As shown, a locking mechanism is provided on one side of the plug housing 2-2. The locking mechanism includes a latch 2-4. A locking groove 2-8 is provided on the side of the plug housing 2-2, which connects to the insertion groove. The latch 2-4 is slidably disposed in the locking groove 2-8 and is located on the moving path of the convex key block 1-1. A spring 2-3 is connected in the locking groove 2-8 and is connected to the latch 2-4. An arc-shaped opening 2-9 for the convex key block 1-1 to pass through is provided on the top surface of the latch 2-4. An inclined surface 3-1 is provided on the end face of the latch 2-4 near the plug 1, and the end face of the latch 2-4 away from the plug 1 is flat. When the spring 2-3 is in its normal state, the inclined surface 3-1 is located on the moving path of the convex key block 1-1, and the plug 1 is connected to the socket 2. When connected, the protruding key block 1-1 on the plug post 1-3 presses against the inclined surface 3-1 on the latch 2-4, causing the latch 2-4 to move and compress the spring 2-3, so that the arc-shaped opening 2-9 aligns with the protruding key block 1-1, thus allowing the plug 1 to be smoothly connected. At this time, the protruding key block 1-1 passes through the arc-shaped opening 2-9, and the latch 2-4 resets under the reaction force of the spring 2-3, causing the protruding key block 1-1 to abut against the plane of the latch 2-4, thereby locking the socket 2 in the insertion direction, so that the plug 1 and the socket 2 can be stably connected together and are not prone to falling off. When it is necessary to separate the plug 1 and the socket 2, press the latch 2-4 to compress the spring 2-3 and move it, so that the arc-shaped opening 2-9 aligns with the protruding key block 1-1, thus separating the plug 1 and the socket 2.
