Description

Technical Field

[0001] This utility model relates to the field of sensor terminal technology, specifically to an anti-loosening mechanical structure for sensor wiring terminals. Background Technology

[0002] In sensor applications, a stable connection between the male and female terminals is crucial for ensuring reliable signal transmission and long-term safe operation of the equipment. Currently, sensor terminals commonly employ mechanical connection methods such as threaded locking, elastic snap-fit, or simple plug-in connections. In practical applications, especially in industrial environments with high vibration and strong impact, these connection methods are prone to loosening due to mechanical vibration, material fatigue, or external interference. This can lead to increased contact resistance, signal transmission interruption, or connection failure, severely impacting the sensor's measurement accuracy and system stability.

[0003] Traditional sensor terminals are not convenient to install and remove due to their threaded locking mechanism, and the simple plug-in connection is not secure enough and is prone to loosening. Moreover, the rigid connection between the male and female ends is prone to fretting wear when subjected to vibration or impact, which can lead to damage to the contact surface and loosening of the connection after long-term use. Utility Model Content

[0004] The purpose of this utility model is to provide a mechanical structure for preventing loosening of sensor terminals, so as to solve the problems mentioned in the background art, such as the inconvenience of threaded locking for disassembly and assembly, the lack of firmness of simple plugging and connection, the easy loosening, and the easy occurrence of fretting wear in the connection part when subjected to vibration or impact, which will lead to damage to the contact surface and loosening of the connection after long-term use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mechanical structure for preventing loosening of a sensor terminal block, comprising a sensor body and further comprising: a female end disposed on one side of the sensor body, wherein a limiting groove is formed on the top surface of the female end, and an elastic component is fixedly disposed on one side of the inner wall of the limiting groove, and an anti-loosening buckle is fixedly disposed at one end of the elastic component; a male end inserted into one side of the female end, wherein a connecting buckle is fixedly disposed on the surface of the male end, a traction drive assembly is sleeved on the surface of the connecting buckle, a rotating rod is fixedly disposed on one side of the traction drive assembly, and a locking strip is fixedly disposed on the top of the rotating rod; and a polyurethane pad disposed on one side of the male end, wherein a silicone rubber pad is fixedly disposed on one side of the polyurethane pad.

[0006] As a preferred embodiment of this utility model, the traction drive assembly includes a plastic connecting rod, a limiting post, and a track piece. The plastic connecting rod is sleeved on the surface of the connecting buckle, the limiting post is fixedly disposed on one side of the plastic connecting rod, and the track piece is sleeved on the surface of the limiting post. The traction drive assembly is used to traction connect the male end and the female end.

[0007] As a preferred technical solution of this utility model, one side of the track piece is rotatably connected to the female end, the surface of the track piece is provided with a track groove, the limiting post is slidably disposed inside the track groove, and both sides of the surface of the female end are fixedly provided with limiting pieces for limiting the plastic connecting rod, and the track groove facilitates the sliding of the limiting post.

[0008] As a preferred embodiment of this utility model, the surface of the plastic connecting rod is provided with a traction groove, the connecting buckle is slidably disposed inside the traction groove, and one end of the traction groove is provided with a release hole to facilitate the separation of the plastic connecting rod and the connecting buckle. The traction groove facilitates the traction of the plastic connecting rod.

[0009] As a preferred embodiment of this utility model, the elastic component includes a fixed rod, an alloy spring, and a sliding rod. One end of the fixed rod and the alloy spring is fixedly connected to one side of the inner wall of the limiting groove. The sliding rod is slidably disposed inside the fixed rod. The other end of the sliding rod and the alloy spring is fixedly connected to the anti-loosening buckle. The elastic component facilitates the movement of the anti-loosening buckle.

[0010] As a preferred embodiment of this utility model, the anti-loosening buckle is slidably disposed inside the limiting groove, and a pull block is fixedly disposed on one side of the anti-loosening buckle, the pull block being used to pull the anti-loosening buckle.

[0011] As a preferred embodiment of this utility model, there are two sets of connecting buckles and two sets of traction drive groups, which are symmetrically arranged. The traction drive group is used for the lead apron connecting buckle.

[0012] Compared with the prior art, this utility model provides an anti-loosening mechanical structure for sensor wiring terminals, which has the following beneficial effects: 1. The anti-loosening mechanical structure of the sensor terminal block, through the setting of traction drive group, connecting buckle and anti-loosening buckle, inserts the male end into the female end, slightly pulls the plastic connecting rod outward and inserts the connecting buckle into the plastic connecting rod from the release hole, and then rotates the rotating rod. The track plate follows the rotation, so that the plastic connecting rod gradually pulls the male end into the female end. When the locking strip is attached to the top surface of the female end, the male end and the female end are completely and tightly locked.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6This utility model discloses an anti-loosening mechanical structure for sensor terminals, including a sensor body 1, and further including: a female terminal 2 disposed on one side of the sensor body 1, the top surface of the female terminal 2 having a limiting groove, a spring component 3 fixedly disposed on one side of the inner wall of the limiting groove, and an anti-loosening buckle 4 fixedly disposed at one end of the spring component 3; and a male terminal 5 inserted into one side of the female terminal 2, the surface of the male terminal 5 being fixedly disposed with a connecting buckle 6, and a traction drive assembly 7 sleeved on the surface of the connecting buckle 6. Through the arrangement of the traction drive assembly 7, the connecting buckle 6, and the anti-loosening buckle 4, Insert the male end 5 into the female end 2, slightly pull the plastic connecting rod 701 outward, and insert the connecting buckle 6 into the plastic connecting rod 701 through the release hole. Then rotate the rotating rod 8, and the track piece 703 rotates accordingly, so that the plastic connecting rod 701 gradually pulls the male end 5 into the female end 2. When the locking strip 9 is attached to the top surface of the female end 2, the male end 5 and the female end 2 are completely and tightly locked. Then the anti-loosening buckle 4 is locked on the top surface of the locking strip 9 to prevent the rotating rod 8 from loosening. This achieves the effect of multiple locking of the male end 5 and the female end 2, improves the stability of the connection, and avoids loosening. A rotating rod 8 is fixedly installed on one side of the traction drive group 7, and a locking strip 9 is fixedly installed on the top of the rotating rod 8. A polyurethane pad 10 is installed on one side of the male end 5, and a silicone rubber pad 11 is fixedly installed on one side of the polyurethane pad 10. Through the installation of the polyurethane pad 10 and the silicone rubber pad 11, the polyurethane pad 10 and the silicone rubber pad 11 resist impact and vibration at the connection between the male end 5 and the female end 2, prevent the connection from loosening due to external force, and also form a flexible contact layer to avoid rigid connection between the male end 5 and the female end 2, which would cause fretting wear and further improve the stability of the connection. At the same time, it also plays a role in auxiliary sealing of the connection between the male end 5 and the female end 2.

[0018] Specifically, the traction drive assembly 7 includes a plastic connecting rod 701, a limiting post 702, and a track piece 703. The plastic connecting rod 701 is sleeved on the surface of the connecting buckle 6, the limiting post 702 is fixedly set on one side of the plastic connecting rod 701, and the track piece 703 is sleeved on the surface of the limiting post 702.

[0019] In this embodiment, rotating the rotating rod 8 causes the track piece 703 to rotate accordingly, so that the plastic connecting rod 701 gradually pulls the male end 5 into the female end 2.

[0020] Specifically, one side of the track piece 703 is rotatably connected to the female end 2, the surface of the track piece 703 is provided with a track groove, the limiting post 702 is slidably disposed inside the track groove, and both sides of the surface of the female end 2 are fixedly provided with limiting pieces for limiting the plastic connecting rod 701.

[0021] In this embodiment, the track groove facilitates the sliding of the limiting post 702, and the track groove gradually gets closer to the rotation connection point between the track piece 703 and the female end 2, so as to achieve the effect of gradually inserting the male end 5 into the female end 2. The limiting pieces set on both sides of the female end 2 can limit the upper and lower sides of the connecting rod 701, thereby ensuring that the track piece 703 can only drive the connecting rod 701 to pull the connecting post 6 to move horizontally in a straight line during the flipping process, so that the male end 5 can be inserted into the female end 2.

[0022] Specifically, the surface of the plastic connecting rod 701 is provided with a traction groove, the connecting buckle 6 is slidably disposed inside the traction groove, and one end of the traction groove is provided with a release hole to facilitate the separation of the plastic connecting rod 701 and the connecting buckle 6.

[0023] In this embodiment, the release hole facilitates the insertion and release of the connecting buckle 6, allowing the male end 5 to be disassembled and installed.

[0024] Specifically, the elastic component 3 includes a fixed rod 301, an alloy spring 302, and a sliding rod 303. One end of the fixed rod 301 and the alloy spring 302 are fixedly connected to one side of the inner wall of the limiting slide groove. The sliding rod 303 is slidably disposed inside the fixed rod 301. The other end of the sliding rod 303 and the alloy spring 302 are fixedly connected to the anti-loosening buckle 4.

[0025] In this embodiment, the elastic component 3 facilitates the opening and resetting of the anti-loosening buckle 4.

[0026] Specifically, the anti-loosening buckle 4 is slidably installed inside the limiting groove, and a pull block 12 is fixedly installed on one side of the anti-loosening buckle 4.

[0027] In this embodiment, the pull block 12 is used to pull the anti-loosening buckle 4.

[0028] Specifically, there are two sets of connecting buckles 6 and two sets of traction drive groups 7, which are symmetrically arranged.

[0029] In this embodiment, the two sets of connecting buckles 6 and the traction drive group 7 make the connection between the male end 5 and the female end 2 more secure.

[0030] The working principle and usage process of this utility model are as follows: the connecting buckle 6 is inserted into the plastic connecting rod 701 through the release hole, and then the male end 5 is inserted into the female end 2. Rotate the rotating rod 8 to one side of the female end 2, causing the track piece 703 to rotate accordingly. As the distance between the track groove and the rotation connection point between the track piece 703 and the female end 2 gradually decreases, the diameter gradually decreases, and the overall length of the plastic connecting rod 701 gradually decreases. The track piece 703 also pulls the plastic connecting rod 701 to move horizontally towards the female end 2, gradually pulling the male end 5 into the female end 2. When the locking strip 9 is attached to the top surface of the female end 2, the male end 5 and the female end 2 are completely and tightly locked together. Before the locking strip 9 is attached, pull the pull block 12 to pull the alloy spring 302 open. When the locking strip 9 is fully attached to the female end 2, the alloy spring 302 drives the anti-loosening buckle 4 to lock on the locking strip 9, preventing the rotating rod 8 from loosening. This multiple locking effect between the male end 5 and the female end 2 improves the stability of the connection and avoids loosening. The polyurethane pad 10 and the silicone rubber pad 11 provide impact and vibration resistance to the connection between the male end 5 and the female end 2, preventing the connection from becoming loose due to external forces. They also form a flexible contact layer, preventing rigid connection between the male end 5 and the female end 2 and causing fretting wear, which further improves the stability of the connection. At the same time, they also serve to help seal the connection between the male end 5 and the female end 2.
