Description
Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a rotatable and adjustable horn connector locking device. Background Technology
[0002] A horn connector is an electrical connector with arc-shaped mating terminals. Its locking device typically uses a jaw structure to fix the connector body, ensuring the stability of electrical contact through mechanical clamping force. Traditional locking devices mostly rely on screw adjustment or fixed clips to open and close the jaws, but they have drawbacks such as low adjustment accuracy and cumbersome operation. In particular, they cannot adapt to the locking requirements of connectors of different sizes. Fixed jaws can only match a single type of connector, which can easily lead to insufficient clamping force or loosening. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0020] To address the problems in the background technology, this utility model proposes a rotatable and adjustable horn connector locking device 2, comprising:
[0021] The housing 1 has an axially extending displacement groove 11 on one side;
[0022] The locking device 2 includes a fixed support 21, a movable support 22, and two sets of grippers 23. The movable support 22 is slidably disposed within a displacement groove 11 of the housing 1. The fixed support 21 is fixedly disposed on the other side of the housing 1. The two grippers 23 are respectively hinged to the fixed support 21 and the movable support 22 via rotating shafts, and the ends of the grippers 23 pass through the displacement groove 11 and extend to the outside of the housing 1.
[0023] The rotary adjustment mechanism 3 includes a knob 31 and a drive assembly 32 located on the outside of the housing 1. The drive assembly 32 connects the knob 31 and the movable support 22, converting the rotational motion of the knob 31 into the linear displacement of the movable support 22 along the displacement groove 11, so as to adjust the distance between the two grippers 23.
[0024] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the housing 1 is a cuboid structure made of plastic or other insulating materials, with an internal cavity to accommodate and protect the internal contact terminals. An elongated displacement groove 11 is formed along the axial direction on one side, with the length of the groove aligned with the mounting axis of the housing 1. The length of the displacement groove 11 is adapted to the fine-tuning displacement range of the movable support 22. A fixed support 21 is fixedly mounted on the other side of the housing 1, rigidly connected to the housing 1 by bolts or integral molding. The movable support 22 is slidably fitted into the displacement groove 11 of the housing 1. Its bottom has a guide groove 42 adapted to the bottom guide rail 41 of the displacement groove 11. Through the sliding engagement of the rail and the guide groove 42, the movable support 22 is restricted to moving only along the axial direction of the displacement groove 11, preventing skewing or jamming. Two sets of grippers 23 are respectively hinged to the fixed support 21 and the movable support 22 via pivots. The middle section of the gripper 23 is the hinge part, and the end is the clamping part. The clamping part of the gripper 23 in the movable support 22 passes through the displacement groove 11 and extends outward from the housing 1, forming a symmetrically arranged arc-shaped clamping structure. In order to enhance the reset capability and clamping stability of the grippers 23, a butterfly spring is pre-installed in the pivot mounting hole of both the fixed support 21 and the movable support 22. The two ends of the butterfly spring abut against the hinge arm of the gripper 23 and the inner wall of the support, respectively, providing a reverse preload force when the gripper 23 swings.
[0025] The rotary adjustment mechanism 3 includes a knob 31 located on the outside of the housing 1 and a built-in drive assembly 32. The drive assembly 32 can be a rack and pinion assembly, a worm gear assembly, or a screw and nut adjustment assembly. Its function is to convert the rotational motion of the knob 31 into the linear displacement of the movable support 22. Specifically, when the knob 31 is rotated, it drives the drive assembly 32, which, through mechanical transmission or other suitable means, causes the movable support 22 to move linearly along the displacement groove 11. The rotation direction of the knob 31 determines the movement direction of the movable support 22. When the user rotates the knob 31 to the right, the drive assembly 32 causes the movable support 22 to move to the right along the displacement groove 11, causing the jaws 23 on both sides to separate outwards, increasing the distance between them. Conversely, when the user rotates the knob 31 to the left, the movable support 22 moves to the left, and the jaws 23 retract inwards, decreasing the distance between them. In this way, users can easily adjust the spacing of the jaws 23 and precisely control the clamping force of the jaws 23 on the connector or component to adapt to connections of different sizes or requirements.
[0026] In one possible implementation, the drive assembly 32 includes an adjusting screw 321 coaxially fixed with the knob 31, and the movable support 22 is provided with a threaded hole 322 that mates with the adjusting screw 321. The adjusting screw 321 passes through the side wall of the housing 1 and forms a threaded transmission pair with the threaded hole 322.
[0027] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the knob 31 is rigidly connected to the end of the adjusting screw 321 via a keyway or interference fit to ensure synchronous rotation. The adjusting screw 321 passes through the mounting hole in the side wall of the housing 1 and extends into the displacement groove 11 in the inner cavity of the housing 1. A copper-based lubricating bushing is embedded in the mounting hole of the housing 1. The inner diameter of the bushing is clearance-fitted with the outer diameter of the adjusting screw 321, providing radial support for the screw and reducing rotational friction resistance through the self-lubricating properties of copper. The movable bearing seat 22 has an internal threaded hole 322 that matches the thread parameters of the adjusting screw 321. When the adjusting screw 321 rotates, the meshing action of the threaded pair drives the movable bearing seat 22 to move linearly along the screw axis.
[0028] In one possible implementation, the bottom of the displacement groove 11 is provided with a guide groove 42 parallel to the axis of the adjusting screw 321, and the bottom of the movable support 22 forms a guide rail 41 adapted to the guide groove 42, and the guide groove 42 and the movable support 22 form a sliding fit.
[0029] Combined with reference Figure 2As shown, in this embodiment, the guide rail 41 is a symmetrically distributed metal protrusion extending axially along the displacement groove 11 and welded or integrally machined to the bottom of the groove. Its cross-section is dovetail-shaped or T-shaped to enhance structural strength and prevent the movable support 22 from detaching from the rail. The bottom of the movable support 22 is correspondingly machined with a guide groove 42 that matches the shape of the rail. The groove depth is slightly greater than the height of the rail, and the two are fitted together to form a sliding pair. The inner surface of the guide groove 42 is coated with a polytetrafluoroethylene wear-resistant coating or fitted with a low-friction coefficient plastic liner to further reduce sliding resistance. When the adjusting screw 321 drives the movable support 22 to move, the fit between the guide rail 41 and the guide groove 42 constrains it to only move linearly along the screw axis, preventing the movable support 22 from shifting or overturning due to the rotational component of the threaded pair. Furthermore, the end of the rail has a chamfered structure to facilitate the initial alignment of the rail and the guide groove 42 during the installation of the movable support 22.
[0030] In one possible implementation, the displacement groove 11 is provided with limiting bosses 5 at both ends, the adjusting screw 321 is provided with a positioning ring 51 at the end, and the inner wall of the limiting bosses 5 is provided with an annular groove 52. The axial positioning ring 51 and the annular groove 52 are fitted together to form an axial limiting structure.
[0031] Combined with reference Figure 1 and Figure 2 As shown, in this embodiment, the limiting boss 5 is a baffle symmetrically welded or integrally formed at both ends of the displacement groove 11. Its height is slightly higher than the bottom surface of the displacement groove 11, forming a mechanical block on the movement stroke of the movable bearing seat 22. The end of the adjusting screw 321 is machined with a positioning ring 51 with an outer diameter slightly larger than the screw body. The positioning ring 51 is made of hardened steel to enhance wear resistance. The inner side of the limiting boss 5 on the inner wall of the housing 1 is machined with an annular groove 52. The width of the groove matches the thickness of the positioning ring 51, and the gap between the two is controlled within the range of 0.05-0.15 mm, so that the positioning ring 51 can be embedded in the groove and rotate freely, while restricting the axial movement of the screw. When the knob 31 drives the adjusting screw 321 to rotate, the positioning ring 51 slides along the inner wall of the groove, which allows the screw to transmit rotational torque, and also prevents the screw from axial displacement through the contact between the side wall of the groove and the end face of the positioning ring 51, preventing the screw from coming out of the housing 1 due to the reverse thrust of the load.
[0032] In one possible implementation, the inner side of the end of the gripper 23 is provided with anti-slip teeth 6, and the teeth of the two grippers 23 are arranged in an interlocking pattern. The arc-shaped clamping surface at the end of the gripper 23 is machined with continuously distributed triangular or trapezoidal teeth, which can prevent the horn connector from slipping off under vibration or load, while dispersing the clamping stress and avoiding local stress concentration that could damage the connector surface.
