Description

Technical Field

[0001] The utility model relates to the field of torque locking connection devices, in particular to a torque locking connection device with firm connection. Background Art

[0002] The torque locking connection device is a fastener commonly used in various electrical systems. It achieves a tight connection between two components through a specific mechanism, ensuring that the connection is not easy to loosen, thus forming a stable integrated structure.

[0003] After searching, a utility model torque locking connection device with the publication number CN207320731U was found, which includes a main body and multiple clamping bolts. The main body includes multiple clamping screw holes and wire insertion holes. The wire insertion holes are perpendicularly intersected with the multiple clamping screw holes. Multiple clamping bolts are detachably arranged in the multiple clamping screw holes. The bolt heads of the multiple clamping bolts include a first bolt head and a second bolt head. The first bolt head is located at the lower end of the second bolt head. The torque locking connection device of the present application has a simple structure and is easy to use. The wiring is achieved by inserting two wires into the wire insertion holes, and then they are clamped and fixed by multiple clamping bolts to prevent them from falling off. The main body covers them to prevent oxidation of the interface; the main body conducts electricity to prevent poor contact; the clamping bolt is provided with two bolt heads and a breaking torque to prevent damage to the wires due to excessive compression.

[0004] The existing torque locking connection device in the above patent basically locks the wires by means of bolts, which are easily pulled during installation. The tightening of the bolts can easily lead to insufficient tightening force, making it easy for the wires to detach from the wire duct, thus affecting use. In the above comparative case, the wires are also simply locked by bolts, resulting in poor connectivity and the wires are easily detached from the locking connection device, affecting normal use.

[0005] Therefore, it is necessary to invent a torque locking connection device with a firm connection to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a torque-locking connection device with a firm connection, which is achieved by placing the wire into the wire trough and then rotating the screw to push the connecting seat and the clamping block up and down. When the clamping block is close to the wire, the clamping block and the movable rod extend and retract in the connecting seat, and the second spring provided on the outside of the movable rod plays the role of rebounding and squeezing the clamping block, so that the clamping block can squeeze the wire, and the anti-sliding block provided on the lower surface of the clamping block can increase the friction between the clamping block and the wire, thereby improving the firmness of the wire connection, so as to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above-mentioned object, the present utility model provides the following technical solutions: a torque locking connection device with a firm connection, comprising a locking connection body;

[0008] A limiting mechanism is installed on both sides of the upper part of the locking connection body for limiting the position.

The upper surfaces of the movable frame are provided with limiting grooves on both sides. The inner surfaces of the locking connection body are provided with wire grooves on both sides.

The upper surfaces of the movable frame 4 are provided with limiting grooves 5. The inner surfaces of the locking connection body 1 are provided with wire grooves 14.

[0030] The screw rod 6 is installed above the movable frame 4 and is used to push the clamping block 11. The outer sleeve of the screw rod 6 is provided with a rubber ring 7. The outer part of the screw rod 6 and the lower part of the rubber ring 7 are provided with a bolt head 8. A connecting seat 9 is provided below the screw rod 6. The connecting seat 9 is movably connected with a movable rod 10 around the four sides. The lower end of the movable rod 10 is fixedly installed with a clamping block 11. The outer part of the movable rod 10 and the lower part of the connecting seat 9 are provided with a second spring 12. An anti-sliding block 13 is provided under the clamping block 11. By placing the wire into the wire groove 14 and then rotating the screw rod 6 to push the connecting seat 9 and the clamping block 11 to rise and fall, when the clamping block 11 is close to the wire, the clamping block 11 and the movable rod 10 extend and retract in the connecting seat 9, and the second spring 12 provided on the outside of the movable rod 10 plays the role of rebounding and squeezing the clamping block 11, so that the clamping block 11 can squeeze the wire, and the anti-sliding block 13 provided on the surface below the clamping block 11 can increase the friction between the wire and the wire, thereby improving the firmness of the wire connection.

[0031] like Figure 1 、 Figure 2 and Figure 6 When the handle 302 is released, the limit block 304 is rebounded and inserted into the limit groove 5 on both sides of the movable frame 4, thereby limiting and fixing the movable frame 4.
