[0002] Connectors in the form of male and female plugs are a connection method widely used in the fields of electronic devices, communication devices, automobiles, etc. Its structure mainly includes a contact part, an insulating part, a fixing part, a shielding part and an accessory part. The contact part is the core of the connector, responsible for realizing electrical or signal connection, usually including contacts on the male head and contacts on the female head. The insulating part is responsible for ensuring electrical isolation between the contact parts to prevent short circuits or arcs, and is usually made of plastic, rubber or other insulating materials. The fixing part is responsible for ensuring the mechanical connection between the male head and the female head to prevent the connector from loosening or falling off during use, and is usually made of metal, plastic or other materials. The shielding part is responsible for preventing the influence of electromagnetic interference on the internal electrical or signal transmission of the connector, and is usually made of metal or other materials. At present, after the docking operation of the male and female plug connectors is completed, the connection points of the male and female plugs are prone to loosening. For example, when the connector is subjected to severe vibration or impact, it is easy to cause the contact part between the male head and the female head to loosen, resulting in a loosening phenomenon, or the metal parts or plastic parts inside the connector are worn, resulting in the loosening of the terminal contact part between the male head and the female head. Therefore, a limiting sleeve needs to be designed. Content of the Utility Model

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-5 , an embodiment provided by the present invention: a limiting sleeve for a connector terminal, including a support base 1 and a retaining ring 8 integrally formed on both sides of the bottom end of the support base 1, and an opening 801 for inserting a male plug is provided on the outer peripheral surface of the retaining ring 8. Through the setting of the opening 801, the male plug connector can be inserted into the retaining ring 8 from the opening 801, so as to ensure that the male plug connector is lifted by the retaining ring 8, facilitating the staff to quickly connect the male plug connector and the female plug connector;

[0019] Notches 3 are provided on both outer walls of the support base 1; a rib seat 2 is integrally formed on one outer wall of the support base 1, and counterbores 201 are provided at both ends of the surface of the rib seat 2. The rib seat 2 is inserted into the outer wall of the control box housing where the female plug connector is located, and the support base 1 and the control box housing are fixedly connected by using the cooperation of bolts and the counterbores 201 to make the structure stable;

[0020] Screw rod lifting structures 5 are provided on both sides inside the support base 1. An arc-shaped holder 7 is installed at the movable end of the screw rod lifting structure 5. The screw rod lifting structure 5 is used to drive the arc-shaped holder 7 to move downward. Knobs 6 for driving the screw rod lifting structure 5 to work are installed on both sides of the top end of the support base 1;

[0021] The arc-shaped holder 7 is made of hard plastic material. A "-" shaped groove extending downward is provided at the top end of the knob 6, which facilitates the staff to rotate the knob 6 by using a flat-head screwdriver through the "-" shaped groove;

[0022] When the arc-shaped holder 7 moves downward and blocks the back of the large head end of the male plug connector, the relative sliding between the male plug and the female plug can be reduced, thereby reducing the wear of the connector, extending the service life of the connector and ensuring the connection stability of the connection;

[0023] The retaining ring 8 includes a nut pair 4 fixed inside the notch 3, a threaded shaft 501 threadedly engaged inside the nut pair 4, and a connecting ring 701 fixed to the top end of the arc-shaped holder 7. The bottom end of the threaded shaft 501 extends into the inside of the connecting ring 701 and is rotatably connected to the connecting ring 701. The top end of the threaded shaft 501 penetrates to the outside of the support base 1 and is fixedly connected to the bottom end of the knob 6;

[0024] When the staff manually turns the knob 6, the knob 6 drives the threaded shaft 501 to rotate. During this process, the nut pair 4 supports the lifting and rotation of the screw rod lifting structure 5. Since the bottom end of the threaded shaft 501 is rotatably connected to the top end of the arc-shaped bracket 7 through the connecting ring 701, the screw rod lifting structure 5 only drives the arc-shaped bracket 7 to lift without rotating it, thereby controlling the height of the arc-shaped bracket 7 so that the arc-shaped bracket 7 stably blocks the back of the large end of the male plug connector, thus preventing the separation of the contact parts of the male plug and the female plug terminals;

[0025] A ring-shaped cutting groove is provided inside the connecting ring 701, and a ring-shaped flange for sliding cooperation with the ring-shaped cutting groove is installed at the bottom end of the threaded shaft 501. Through the ring-shaped flange and the ring-shaped cutting groove, the connecting ring 701 and the threaded shaft 501 are kept in a relative rotating state;

[0026] A columnar groove 101 is provided on the back of the support base 1, and the threaded shaft 501 is concentric with the columnar groove 101.

[0027] When the embodiment of the present application is in use, first, the staff fixes the ribbed seat 2 to the outer wall of the control box housing where the female plug connector is located. Then, the male plug connector to be connected to the female plug connector is taken out, so that the male plug connector is inserted into the support ring 8, and the male plug connector and the female plug connector are inserted into each other until they are stably inserted and the terminals are kept in electrical connection. At this time, the staff can manually turn the knob 6 so that the screw rod lifting structure 5 drives the arc-shaped bracket 7 to move down until the arc-shaped bracket 7 contacts the outer peripheral surface of the female plug connector and the arc-shaped bracket 7 blocks the back of the large end of the male plug connector, so that the male plug connector and the female plug connector always maintain a stable inserted and connected state, effectively preventing the separation of the contact parts of the male plug and the female plug terminals, so that it can be ensured that the connector can still maintain a stable connection state when subjected to vibration and impact changes, and the reliability of the connector is improved.
