Description

Technical Field

[0001] This utility model relates to the technical field of connectors, and more particularly to a novel signal connector. Background Technology

[0002] Signal connectors are widely used in industrial automation, outdoor lighting, automotive electronics and other fields. Existing signal connectors include plugs and sockets, which are used to carry current and transmit signals. Therefore, the stability of the plugging and the stability of the signal transmission are determined by the stability of the plugging and the current transmission. The plugging stability of current signal connectors mainly relies on the insertion and extraction force of the plug and socket. There is no additional locking mechanism. When plugging and unplugging frequently, the two are prone to loosening, which affects the connection stability. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this invention provides a novel signal connector.

[0004] This utility model provides a novel signal connector, including a connector socket, a connector plug, and a locking mechanism. The state in which the connector socket and the connector plug are inserted is defined as the insertion state. The locking mechanism is used to lock the connector plug onto the connector socket in the insertion state. The locking mechanism includes a locking handle that is axially connected to the connector plug and can rotate relative to the connector plug, a curved groove provided on the locking handle, a locking pin provided on the connector socket that cooperates with the curved groove, and a locking block for preventing the locking handle from rotating relative to the connector plug in the insertion state.

[0007] Furthermore, the locking post includes a sliding section connected to the connector socket and a limiting section connected to the sliding section with a cross-sectional diameter larger than that of the sliding section. The curved groove has an opening for the limiting section to enter, the width of which is greater than that of the limiting section. And / or the curved groove has a variable diameter channel for the locking post to enter, the variable diameter channel having an opening with a width greater than that of the limiting section and a narrowing section adjacent to the opening whose width gradually decreases to be equal to that of the limiting section.

[0008] Furthermore, one of the connector plug and the body is provided with a sliding groove, and the other is provided with a sliding block that cooperates with the sliding groove.

[0009] Furthermore, the connector socket includes a housing and a first terminal assembly limited within the housing, and the locking post is disposed on the outer surface of the housing; the connector plug includes a insert and a second terminal assembly limited within the insert; the curved groove is disposed on the outer surface of the insert and the locking handle is axially connected to the outer surface of the insert.

[0010] Furthermore, the first terminal assembly includes a first terminal sleeve and a current pin and a signal pin disposed within the first terminal sleeve; the second terminal assembly includes a second terminal sleeve disposed within the housing, a signal socket and a terminal socket disposed within the second terminal sleeve.

[0022] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Moreover, the features in the embodiments of the present invention can be combined with each other without conflict.

[0023] like Figures 1-7 As shown, this utility model provides a novel signal connector, including a connector socket 1, a connector plug 2, and a locking mechanism. The state in which the connector socket 1 and the connector plug 2 are plugged in is defined as the plugged state. The locking mechanism is used to lock the connector plug 2 onto the connector socket 1 in the plugged state. The locking mechanism includes a locking handle 31 that is axially connected to the connector plug 2 and can rotate relative to the connector plug 2, a curved groove 32 provided on the locking handle 31, a locking pin 33 provided on the connector socket 1 that cooperates with the curved groove 32, and a locking block 34 for preventing the locking handle 31 from rotating relative to the connector plug 2 in the plugged state.

[0024] In this embodiment, after the connector socket 1 and the connector plug 2 are inserted, the locking handle 31 is rotated to fix the connector plug 2 and the connector socket 1 together. The locking block 34 blocks the rotation path of the locking handle 31, thereby preventing the locking handle 31 from rotating. This achieves the locking effect of the locking handle 31 on the connector plug 2 and the connector socket 1 when they are in the inserted state. That is, when the locking handle 31 is restricted from rotating by the locking block 34, one end of the locking handle 31 is connected to the connector plug 2 and the other end is connected to the curved groove 32, thereby preventing the connector socket 1 and the connector plug 2 from disengaging and achieving a stable insertion state for both.

[0025] In one specific embodiment, the locking block 34 includes a main body 341 and a spring piece 342 connected to the main body 341. The end of the spring piece 342 away from the main body 341 is provided with a snap-fit ​​protrusion 3421. The locking handle 31 is provided with a snap-fit ​​protrusion 311 that mates with the snap-fit ​​protrusion 3421. In this embodiment, the spring piece 342 and the surface of the connector plug 2 have a travel gap. In the plugged-in state, the snap-fit ​​protrusion 3421 and the snap-fit ​​protrusion 311 are in contact, thereby ensuring that there is a gap between the snap-fit ​​protrusion 3421 and the snap-fit ​​protrusion 311 when the locking handle 31 is rotated. The locking handle 31 is unable to rotate, thus preventing the connector socket 1 and connector plug 2 from being disengaged. When unlocking is required, simply press the spring 342 to move it toward the surface of the connector socket 1. At this time, the height of the locking protrusion 3421 is lower than the height of the locking protrusion 311, so the locking protrusion 3421 no longer interferes with the rotation of the locking protrusion 311, allowing the locking handle 31 to rotate and thus release the locking effect, allowing the connector socket 1 and connector plug 2 to be disengaged.

[0026] In one specific embodiment, the surface of the connector plug 2 is further provided with a limiting arm 25, which forms a limiting groove 26 with the surface of the connector plug 2. The main body 341 is partially located within the limiting groove 26. In the plugged-in state, at least a portion of the locking protrusion 3421 is at the same height as the limiting arm 25, so that when the locking block 34 moves away from the connector socket 1, the end face of the limiting arm 25 can abut against the locking protrusion 3421, thereby preventing the locking block 34 from moving away from the locking protrusion 311. With the interference effect on the rotation of the locking protrusion 311 gone, when it is necessary to release the rotation restriction of the locking handle 31 by the locking block 34, simply press the spring piece 342 so that the height of the locking protrusion 3421 is less than the height of the locking arm. At this time, the locking block 34 can be pulled away from the connector socket 1, so that the locking protrusion 3421 no longer interferes with the locking protrusion 311, thereby allowing the locking handle 31 to rotate. During this rotation process, due to the presence of the curved groove 32, the connector plug 2 can be pushed to separate from the connector socket 1 simultaneously.

[0027] In one specific embodiment, the connector plug 2 is provided with a insertion groove 211, and the end of the spring piece 342 away from the main body 341 is provided with an extension 3422. When not in the insertion state, the extension 3422 abuts against the groove wall of the insertion groove 211. When in the insertion state, the extension 3422 is inserted into the insertion groove 211. In this embodiment, when the locking handle 31 is not rotated to the position corresponding to the locking state, the locking protrusion 311 is not in contact with the locking protrusion 3421, so the extension 3422 abuts against the groove wall of the insertion groove 211. At this time, when pushing the locking block 34 towards the connector socket 1, due to the abutment of the groove wall of the insertion groove 211, the user cannot push the locking block 34 towards the connector socket 1, thus... Feedback indicates that the connector socket 1 and connector plug 2 are not properly inserted. When the connector plug 2 is properly inserted into the connector socket 1, the locking handle 31 rotates to a position where the locking protrusion 3421 contacts the locking lug 311. This causes the spring piece 342 to elastically deform and move towards the surface of the connector plug 2, so that the extension 3422 is opposite to the insertion groove 211. At this time, the user can push the locking block 34 towards the insertion groove 211, indicating that the connector plug 2 and connector socket 1 are properly inserted. When the extension 3422 is inserted into the insertion groove 211, when the locking handle 31 is to be rotated, the bottom of the spring piece 342 is abutted by the bottom of the insertion groove 211, thereby further increasing the interference of the locking protrusion 3421 with the locking lug 311.

[0028] In an optional embodiment, the locking pin 33 includes a sliding section 331 connected to the connector socket 1 and a limiting section 332 connected to the sliding section 331 and having a cross-sectional diameter larger than that of the sliding section 331. The curved groove 32 has an opening 321 for the limiting section 332 to enter, and the width of the opening 321 is larger than the cross-sectional diameter of the limiting section 332. In the initial state, the opening 321 faces the locking pin 33, so that when the connector plug 2 is inserted into the connector socket 1, the locking pin 33 can enter the curved groove 32 from the opening 321. When the locking handle 31 is rotated, under the guidance of the curved groove 32, the connector socket 1 and the connector plug 2 can be moved towards each other, thereby achieving the insertion of the two.

[0029] In an optional embodiment, the curved groove 32 has a variable diameter channel for the locking pin 33 to enter. The variable diameter channel has an opening 321 with a width greater than the cross-sectional diameter of the limiting section 332 and a narrowing section adjacent to the opening 321 whose width gradually decreases to be equal to the cross-sectional diameter of the limiting section 332. In the initial state, the opening 321 faces the locking pin 33, so that when the connector plug 2 is inserted into the connector socket 1, the locking pin 33 can enter from the opening 321 and enter the curved groove 32 along the narrowing section. At this time, rotating the locking handle 31 can drive the connector socket 1 and the connector plug 2 to move towards each other under the guidance of the curved groove 32, thereby achieving the insertion of the two.

[0030] In one specific embodiment, one of the connector plug 2 and the main body 341 is provided with a sliding groove 343, and the other is provided with a sliding block 212 that cooperates with the sliding groove 343. Through the cooperation of the two, the locking block 34 can move smoothly relative to the connector plug 2. Specifically, the sliding groove 343 is provided on the main body 341 and there are multiple sliding grooves, and the sliding block 212 is provided on the connector plug 2 and corresponds one-to-one with the multiple sliding grooves 343.

[0031] In one specific embodiment, the connector socket 1 includes a housing 11 and a first terminal assembly limited within the housing 11, and the locking post 33 is disposed on the outer surface of the housing 11; the connector plug 2 includes a insertion shell 21 and a second terminal assembly limited within the insertion shell 21; the curved groove 32 is disposed on the outer surface of the insertion shell 21 and the locking handle 31 is axially connected to the outer surface of the insertion shell 21.

[0032] Further, the first terminal assembly includes a first terminal sleeve 12 and a current pin 13 and a signal pin 14 disposed within the first terminal sleeve 12; the second terminal assembly includes a second terminal sleeve 22 disposed within the housing 21, a signal socket 23 disposed within the second terminal sleeve 22, and a terminal socket 24 disposed within the second terminal sleeve 22. When the connector socket 1 is inserted into the connector plug 2, the current pin 13 is inserted into the terminal socket 24, and the signal pin 14 is inserted into the signal socket 23. The current pin 13 is a high-current pin 13.

[0033] In an optional embodiment, the current pin 13 can be fixed inside the housing 11 by its own metal sheet, and the signal pin 14 can be fixed inside the housing 11 by the plastic spring 342 inside the housing 11. After the current pin 13 and the signal pin 14 are fixed inside the housing 11, the first terminal sleeve 12 is pushed into the housing 11. At this time, the plastic claws inside the first terminal sleeve 12 can press the housing 11, thereby preventing the current pin 13 and the signal pin 14 from falling off.

[0034] In one specific embodiment, one of the housing 11 and the insert housing 21 is provided with a guide protrusion 111, and the other is provided with a guide slot 213 that cooperates with the guide protrusion 111. Through the cooperation of the guide protrusion 111 and the guide slot 213, the connector socket 1 and the connector slot can achieve a guiding and positioning function when they are inserted.

[0035] In one specific embodiment, the plug housing 21 is provided with a plug sealing ring 41, which is installed inside the plug housing 21 to achieve a waterproof function after mating with the seat housing 11.

[0036] In one specific embodiment, the housing 11 is provided with a socket sealing gasket 42, which has multiple sealing protrusions. The sealing protrusions of the socket sealing gasket 42 are fixed in the sealing groove of the housing 11 to ensure that the connector socket 1 is squeezed after installation with the mating equipment housing, thereby achieving waterproof performance.

[0037] In one specific embodiment, at least one of the current pin 13, the signal pin 14, and the terminal socket is provided with a crimp sealing plug, thereby enabling the cable to be sealed after being connected to the cable.

[0038] In one specific embodiment, the housing 11 is provided with a mounting surface, and the mounting surface is injection molded with a metal threaded sleeve 43, which can enhance the bolt installation torque performance of the connector socket 1.
