Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an electric connector with an anti-loosening function. Background Art

[0002] An electrical connector is a device used to connect circuits, which allows current to be transmitted between different electronic devices or components. Common electrical connectors include plugs, sockets, etc.

[0003] There are many types of electrical connectors, which are widely used. Among them, the commonly used electrical connectors on electrical cabinets are round-headed electrical connectors. The existing electrical connectors are directly plugged into the electrical cabinet during installation. The connection friction between the electrical connector and the electrical cabinet is not high enough, which makes the electrical connector easy to loosen, affecting the use. Therefore, in view of the above situation, it is urgent to develop an electrical connector with high installation stability and anti-loosening function that is not easy to loosen and fall off, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of the utility model is to provide an electrical connector with an anti-loosening function to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An electrical connector with an anti-loosening function comprises an electrical plug connector, a reinforcement block, a tension spring and a tightening mechanism, wherein the electrical plug connector is provided with an installation groove, two reinforcement blocks are installed in the installation groove, the two reinforcement blocks are elastically connected by a tension spring, the outer side of the reinforcement block is provided with anti-slip grooves, and two tightening mechanisms for tightening the reinforcement blocks are installed on the electrical plug connector, the tightening mechanism comprises: a threaded rod and a tightening guide head, the threaded rod is connected to the electrical plug connector by threads, a tightening guide head is fixed to the front end of the threaded rod, the outer surface of the tightening guide head is in a truncated cone shape, the diameter of the tightening guide head gradually increases from right to left, and the inner ring of the reinforcement block is provided with a semicircular slot for inserting the tightening guide head.

[0007] Preferably, the reinforcement block is in a semicircular ring shape, and the reinforcement block slides in the installation groove.

[0008] Preferably, the thickness of the reinforcement block is the same as the width of the installation groove.

[0009] Preferably, the diameter of the semicircular slot is larger than the diameter of the rightmost end of the tightening guide head and smaller than the diameter of the leftmost end of the tightening guide head.

[0010] Preferably: a plurality of toggle rods are fixed to the left end of the threaded rod.

[0011] The beneficial effect of the utility model is as follows: when the electrical connector with anti-loosening function is used, the front half of the electrical plug connector is first inserted into the electrical installation hole on the electrical cabinet, and then the toggle rod is turned by hand to drive the threaded rod and the tightening guide head to move forward, so that the tightening guide head is gradually inserted into the semicircular slot. Since the outer surface of the tightening guide head is in the shape of a truncated cone and the diameter of the tightening guide head gradually increases from right to left, the tightening guide head gradually lifts the reinforcement block outward, so that the reinforcement block is tightly pressed against the inner wall of the electrical cabinet. The friction between the reinforcement block and the electrical cabinet is increased by setting the anti-slip pattern, thereby increasing the connection stability between the reinforcement block, the electrical plug connector and the electrical cabinet, and preventing the electrical plug connector from loosening. In summary, the utility model has high installation stability and is not easy to loosen or fall off. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Specific examples are given below.

[0021] See also Figure 1 to Figure 5In an embodiment of the utility model, an electrical connector with an anti-loosening function comprises an electrical plug connector 1, a reinforcement block 3, a tension spring 4, a tightening mechanism 5 and an electrical cabinet 6. The electrical plug connector 1 is provided with a mounting groove 2, and two reinforcement blocks 3 are installed in the mounting groove 2. The reinforcement blocks 3 are in a semicircular ring shape, and the two reinforcement blocks 3 are elastically connected by a tension spring 4. The reinforcement blocks 3 slide in the mounting groove 2, and the thickness of the reinforcement blocks 3 is the same as the width of the mounting groove 2. The outer side of the reinforcement blocks 3 is provided with anti-slip grooves 301. Two tightening mechanisms 5 for tightening the reinforcement blocks 3 are installed on the electrical plug connector 1. The tightening mechanism 5 comprises: a threaded rod 501 and a tightening guide head 502. The threaded rod 501 is connected to the electrical plug connector 1 through threads, and a tightening guide head 502 is fixed to the front end of the threaded rod 501. The outer appearance of the tightening guide head 502 is in the shape of a truncated cone, and the diameter of the tightening guide head 502 gradually increases from right to left. The inner circle of the reinforcement block 3 is provided with a semicircular slot 302 for inserting the tightening guide head 502. The diameter of the semicircular slot 302 is larger than the diameter of the rightmost end of the tightening guide head 502 and smaller than the diameter of the leftmost end of the tightening guide head 502. A plurality of toggle rods 5011 are fixed to the left end of the threaded rod 501. The threaded rod 501 can be moved by rotating the toggle rods 5011. The front half of the electrical plug connector 1 is inserted into the electrical installation hole on the electrical cabinet 6.

[0022] Working principle: When using the electrical connector with anti-loosening function, first insert the front half of the electrical plug connector 1 into the electrical installation hole on the electrical cabinet 6, and then turn the toggle rod 5011 by hand to drive the threaded rod 501 and the tightening guide head 502 to move forward, so that the tightening guide head 502 is gradually inserted into the semicircular slot 302. Since the outer surface of the tightening guide head 502 is in the shape of a truncated cone and the diameter of the tightening guide head 502 gradually increases from right to left, the tightening guide head 502 gradually lifts the reinforcement block 3 outward, so that the reinforcement block 3 is tightly pressed against the inner wall of the electrical cabinet 6. The friction between the reinforcement block 3 and the electrical cabinet 6 is increased by setting the anti-slip pattern 301, thereby increasing the connection stability between the reinforcement block 3, the electrical plug connector 1 and the electrical cabinet 6, and preventing the electrical plug connector 1 from loosening.
