[0002] An electrical connector consists of a female contact and a male contact. It is a component used to connect two electronic devices through a circuit. It usually comes in a variety of styles, such as a circular electrical connector or a rectangular electrical connector. A circular electrical connector is usually connected by threads. After the electrical connector is connected, it is fixed by threads to prevent it from loosening and falling off.

[0003] Existing circular electrical connectors that are connected by threads require the two ends of the electrical connector to be gradually rotated until they are tightened during connection, which is inconvenient to operate. In addition, if the operation is not careful during connection, the threads may be easily disengaged, resulting in the electrical connector being unable to be tightly connected. In addition, when the electrical connector is accidentally touched, it is easy to rotate, causing the threads to gradually disengage, making it easy for it to fall off. Utility Model Content

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] In view of the above problems existing in the existing anti-dropping type electrical connector, the present utility model is proposed.

[0006] Therefore, the purpose of the utility model is to provide an anti-falling electrical connector, which is designed to solve the problem that "the existing circular electrical connector connected by threads requires the two ends of the electrical connector to be gradually rotated until tightened during connection, which is inconvenient to operate, and if the operation is not careful during connection, the threads may easily be disengaged, resulting in the electrical connector being unable to be tightly connected. In addition, when the electrical connector is accidentally touched, it is easy to rotate, causing the threads to gradually disengage, and thus easily fall off."

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: an anti-drop-off type electrical connector, comprising:

[0008] The main unit comprises a connecting female head, the outer wall of which is rotatably connected to a swivel on the left side, and a plurality of anti-falling components are arranged on the right side of the swivel;

[0013] As a preferred solution of the anti-fall-off electrical connector described in the utility model, a protective shell is provided on the outside of the spring, and the protective shell is fixedly connected to the outer wall of the connecting female head, and the protective shell prevents the spring from bending outward or falling outward.

[0014] As a preferred solution of the anti-drop-off electrical connector described in the utility model, a through groove is provided on the side of the protective shell close to the swivel, the inner side of the through groove is an arc-shaped edge and the arc is the same as the arc of the swivel, and the pin moves along the inside of the through groove.

[0015] Beneficial effects of the utility model:

[0016] When in use, the connecting female head is connected with the connecting sub-head.

[0026] Reference Figure 1-3 The utility model provides an anti-drop-off type electrical connector, comprising:

[0027] The main unit 100 includes a female connector 101, a swivel 102 is rotatably connected to the left side of the outer wall of the female connector 101, and a plurality of anti-drop components 103 are arranged on the right side of the swivel 102;

[0028] The connecting unit 200 includes a connecting sub-head 201, and a connecting sleeve 202 is fixedly connected to the left side of the outer wall of the connecting sub-head 201. The outer wall diameter of the connecting sleeve 202 is smaller than the inner ring diameter of the rotating ring 102. The outer wall of the connecting sleeve 202 is provided with a plurality of connecting grooves 203, and the connecting grooves 203 are folded.

[0029] Among them, a plurality of connecting blocks 102b are fixedly connected to the left side of the inner wall of the rotating ring 102, and the connecting blocks 102b are clamped with the connecting grooves 203. Then, the connecting blocks 102b are driven to rotate by the rotating ring 102, so that the connecting blocks 102b are clamped into the folded part of the connecting grooves 203, thereby connecting and fixing the connecting female head 101 and the connecting sub-head 201.

[0030] Furthermore, a handle 102a is fixedly connected to the outer wall of the swivel 102, and a plurality of protrusions for increasing friction are provided on the surface of the handle 102a to facilitate the staff to manually rotate the swivel 102. A limiting ring 102c is fixedly connected to the right side of the inner wall of the swivel 102, and a limiting groove movably connected to the limiting ring 102c is provided on the outer wall of the connecting female head 101. The limiting ring 102c rotates along the limiting groove to prevent the swivel 102 from moving sideways, and the swivel 102 and the connecting female head 101 are rotatably connected.

[0031] Furthermore, the anti-fall-off component 103 includes a spring 103a, and the two ends of the spring 103a are respectively movably connected with a pin 103b and a fixed block 103c, the fixed block 103c is fixedly connected to the outer wall of the connecting female head 101, and the pin 103b is fixedly connected to the right side of the swivel 102. The rebound force of the spring 103a prevents the swivel 102 from rotating outward autonomously to cause the connecting block 102b to disengage from the connecting groove 203, thereby preventing the connecting female head 101 and the connecting sub-head 201 from loosening and falling off.

[0032] Furthermore, a protective shell 103d is provided on the outside of the spring 103a, and the protective shell 103d is fixedly connected to the outer wall of the connecting female head 101. The protective shell 103d prevents the spring 103a from bending outward or falling off outward, thereby preventing the spring 103a from being accidentally torn off or losing its elasticity.

[0033] Furthermore, a through slot 103e is provided on one side of the protective shell 103d close to the swivel 102, and the inner side of the through slot 103e is an arc-shaped edge and the arc is the same as the arc of the swivel 102. The pin 103b moves along the inside of the through slot 103e, thereby preventing the pin 103b from being stuck by the protective shell 103d, causing the spring 103a to be unable to retract normally.

[0034] During use, the female connector 101 is connected to the sub-connector 201. As the female connector 101 and the sub-connector 201 gradually approach each other, the connecting block 102b is held against the connecting sleeve 202. Then, the sleeve 102a is used to rotate the swivel 102, and the swivel 102 drives the connecting block 102b to rotate to the radial part of the connecting groove 203. At the same time, the swivel 102 drives the pin 103b to move along the through groove 103e and stretch the spring 103a. Then, the female connector 101 is continued to be connected to the sub-connector 201, so that the connecting block 102b is inserted into the connecting groove 203. The swivel 102 is moved to its deepest point, and then the swivel 102 is released. The spring 103a rebounds and drives the swivel 102 to reset, so that the connecting block 102b is stuck in the folded part of the connecting groove 203. The elastic force applied by the spring 103a prevents the swivel 102 from rotating autonomously, causing the connecting block 102b to be separated from the lateral part of the connecting groove 203, thereby preventing the connecting female head 101 and the connecting sub-head 201 from loosening and falling off. The connection between the connecting female head 101 and the connecting sub-head 201 can be completed by rotating the swivel with an amplitude of less than one circle, and it automatically rotates to fix after loosening, which is convenient for operation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
