It is widely used in various electronic components such as automotive connectors, PCB boards and computer connectors. However, the traditional PIN pin structure also has certain defects. The PIN pin body may fall off when plugged in.

[0003] In this regard, after checking, the publication number CN217086948U discloses an anti-falling PIN needle structure, including a PIN needle body and a protective sleeve, the PIN needle body is in contact with the protective sleeve, the PIN needle body is fixedly connected with a contact terminal, a limiting hole is provided inside the PIN needle body, an open groove is provided inside the protective sleeve, a movable plate is slidably connected in the open groove, a limiting rod is fixedly connected on the movable plate, the limiting rod is slidably connected with the limiting hole, an articulated seat is fixedly connected to the PIN needle body, a support plate is hinged in the articulated seat, a first welding point is fixedly connected to the support plate, and a second welding point is fixedly connected to the PIN needle body; by pushing the PIN needle body into the electronic connector, under the cooperation of the spring and the articulated seat, the support plate drives the friction pad to always contact with the inner wall of the electronic connector and be in a tensioned state to complete the clamping action and avoid the falling-off problem of the PIN needle body.

[0004] The above technology can prevent the PIN from falling off by pushing it into the electrical connector, and can prevent the PIN from falling off by using the cooperation of the spring, the support plate and the friction pad.

[0024] 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 in 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.

[0025] like Figures 1 to 3 As shown, an impact-resistant PIN pin proposed in this embodiment includes a PIN pin body 1, on which a reinforcing rib 101 is embedded and fixed, wherein the right end of the PIN pin body 1 is provided with an embedding groove fixedly connected to the outer side of the reinforcing rib 101, and the provided reinforcing rib 101 is used to strengthen the strength of the PIN pin body 1, thereby enhancing its impact resistance effect, and the right end of the reinforcing rib 101 is fixedly provided with a terminal head 102, and the left end of the PIN pin body 1 is a plug part;

[0026] The PIN needle body 1 and the outer side of the reinforcing rib 101 are slidably sleeved with the same sleeve 2 with a blocking structure on the right side. A sliding through hole 201 that is in active contact with the outer side of the reinforcing rib 101 is opened on the right inner wall of the sleeve 2, which plays the effect of allowing the reinforcing rib 101 to move through. An elastic support buffer component is installed between the right inner wall of the sleeve 2 and the right end of the PIN needle body 1. The elastic support buffer component is used to buffer and unload force when the PIN needle body 1 or the end head 102 is accidentally impacted before use, and the risk of damage to the PIN needle body 1 by impact is reduced by buffering and unloading force, thereby improving its impact resistance, and is used to perform elastic tightening support after plug-in connection, and utilizes elastic tightening support to prevent the PIN needle body 1 from being separated from the connection part due to factors such as vibration; four elastic support anti-detachment components are arranged in a ring shape with equal intervals on the outer side of the sleeve 2, and the elastic support anti-detachment component is used to perform anti-slip tightening and anti-detachment when inserting the electrical connector.

[0027] Specifically, the elastic support buffer assembly includes a first spring 301 fixedly connected to the right inner wall of the casing 2, the left end of the first spring 301 is fixedly connected to a fixing ring 3, the left side of the fixing ring 3 is fixedly connected to the right end of the PIN needle body 1, the first spring 301 is sleeved on the reinforcing rib 101 and does not contact the outer side of the reinforcing rib 101, the fixing ring 3 and the casing 2 are both made of insulating hard plastic; the first spring 301 and the fixing ring 3 cooperate to play the role of elastic support between the right end of the PIN needle body 1 and the right inner wall of the casing 2, and when the PIN needle body 1 is accidentally impacted, the fixing ring 3 can be driven to compress the first spring 301, and when the end head 102 is accidentally impacted When the PIN pin body 1 is struck, the fixing ring 3 can be driven to stretch the first spring 301 in turn through the reinforcing rib 101 and the PIN pin body 1, and the elastic force of the first spring 301 can be used to achieve the effect of buffering and unloading the PIN pin body 1 when it is accidentally hit before use. In addition, after being inserted into the electrical connector, the sleeve 2 continues to be pushed in the insertion direction to semi-compress the first spring 301. The semi-compressed first spring 301 can always have an elastic force on the PIN pin body 1. By using this elastic force, it can be ensured that the PIN pin body 1 and the electrical connector are always plugged and fitted, and the phenomenon of separation of the PIN pin body 1 and the connection part due to factors such as vibration can be prevented, thereby ensuring stable use.

[0028] Furthermore, the spring support anti-detachment component includes an arc-shaped spring piece 4, one end of which is fixedly connected to the outside of the casing 2, and two opposite arc-shaped spring pieces 4 are symmetrically arranged, and a second spring 401 is fixedly connected between the inner side of the arc-shaped spring piece 4 and the outer side of the casing 2, wherein the outer side of the casing 2 is provided with four circular grooves at equal intervals in an annular shape, and the inner wall of the circular groove on the side away from its opening is fixedly connected to the corresponding second spring 401 at one end away from the arc-shaped spring piece 4, and the second spring 401 is fixedly connected to the outer side of the casing 2 through the corresponding circular grooves, and the outer side of the casing 2 is provided with four sliding grooves at equal intervals in an annular shape, and a slider 5 is slidably installed on the inner wall of the side of the sliding groove away from its opening, wherein a T-shaped guide rail 501 is fixedly connected to the inner wall of the side of the sliding groove away from its opening, and the side of the sliding groove 5 close to the reinforcing rib 101 is provided with a The T-shaped guide groove is provided at the opening, and the T-shaped guide groove is slidably connected with the corresponding T-shaped guide rail 501, so as to guide the lateral sliding of the slider 5. The other end of the arc-shaped spring piece 4 is hinged with the corresponding outer side of the slider 5, and the outer side of the arc-shaped spring piece 4 is bonded and fixed with an anti-skid rubber 402; the arc-shaped spring piece 4, the second spring 401, the slider 5 and the anti-skid rubber 402 cooperate with each other, and when the sleeve 2 is inserted into the electrical connector, the four arc-shaped spring pieces 4 are driven to be squeezed with the inner wall of the socket of the electrical connector. Under the squeezing force, the four arc-shaped spring pieces 4 are compressed inwardly and compress the four second springs 401. The elastic force of the second spring 401 and the arc-shaped spring piece 4 is used to tighten the anti-skid rubber 402 in the socket of the electrical connector, and the anti-skid effect of the anti-skid rubber 402 is cooperated to achieve the effect of anti-skid, tightening and preventing from falling off.

[0029] The method of using this embodiment is as follows: the reinforcing rib 101 can be used to enhance the impact resistance of the PIN needle body 1. In addition, when not in use, when the PIN needle body 1 is accidentally impacted, it will slide to the right in the housing 2 and drive the fixing ring 3 to compress the first spring 301. When the end portion 102 is accidentally impacted, the reinforcing rib 101 and the PIN needle body 1 can be used to drive the fixing ring 3 to stretch the first spring 301 in turn. The elastic force of the first spring 301 is used to achieve the effect of buffering and unloading the PIN needle body 1 when it is accidentally impacted before use. The elastic buffering and unloading can reduce the risk of the PIN needle body 1 being damaged by impact, and further improve its impact resistance when not in use.

[0030] When inserting into the electrical connector, the sleeve 2 is pushed to drive the PIN needle body 1 to be inserted into the electrical connector. When the PIN needle body 1 is in contact with the connection point on the inner side of the electrical connector, it is blocked and restricted by the connection point. At this time, the sleeve 2 is continued to be pushed and inserted into the socket of the electrical connector. When the sleeve 2 is inserted, the four arc-shaped spring pieces 4 are driven to squeeze with the inner wall of the socket of the electrical connector. Under the squeezing force, the four arc-shaped spring pieces 4 are compressed inwardly and compress the four second springs 401. The elastic force of the second springs 401 and the arc-shaped spring pieces 4 is used to make the anti-skid rubber 402 always tightly fit in the socket of the electrical connector. With the anti-skid effect of the anti-skid rubber 402, the effect of elastic tightening, fixing and preventing falling off in the electrical connector is achieved, so as to realize the function of preventing the PIN needle body 1 from falling off after insertion.

[0031] After the PIN needle body 1 is in contact with the connection point on the inner side of the electrical connector, and the sleeve 2 is pushed and inserted further, the sleeve 2 will slide on the PIN needle body 1 and compress the first spring 301, so that the first spring 301 is in a semi-compressed or slightly compressed state. The compressed first spring 301 can always exert an elastic force on the PIN needle body 1 through the fixing ring 3. By utilizing this elastic force, the PIN needle body 1 and the electrical connector can be always plugged and fitted, and the PIN needle body 1 can be prevented from being separated from the connection part due to factors such as vibration, thereby ensuring the stability of use, and automatically overcoming the displacement caused by factors such as vibration during insertion and use, and ensuring the effect of stable contact connection of the PIN needle body, thereby improving the long-term stability of use. In addition, the first spring 301 can realize the dual functions of buffering and unloading protection before use and tightening and stabilizing connection during insertion and use, without the need to separately set up a protective cover for impact resistance protection when not in use, so that no discarded parts will be generated separately during use, thereby avoiding waste.
