Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a pin structure for a new energy vehicle connector. Background Art

[0002] New energy vehicle connectors will use PIN pin bodies. Connectors are also called connectors, and are also called joints and sockets in China. They generally refer to electrical connectors, that is, devices that connect two active devices to transmit current or signals. The PIN pin body is a metal material used in the connector to complete electrical conduction.

[0003] The connector of new energy vehicles is prone to loose interfaces during use. The use of screws and nuts on both sides for threaded connection is too time-consuming and labor-intensive. At the same time, most connector PIN pins are difficult to replace after being damaged, which often leads to the entire connector being scrapped. For this reason, we propose a pin pin structure for new energy vehicle connectors. Utility Model Content

[0004] The purpose of the utility model is to provide a pin structure for a new energy vehicle connector to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a pin needle structure for a new energy vehicle connector, comprising a connector joint with a cable and a pin needle body, a plurality of pin needle bodies are evenly distributed in the connector joint, and limit blocks are evenly arranged on the outside of the pin needle body, and an external thread is arranged at the tail of the pin needle body. The pin needle body is threadedly electrically connected to the metal threaded hole inside the connector joint through the external thread, and an air release groove is evenly arranged on the outside of the pin needle body. The utility model sets the pin needle body as a structure with an external thread at the tail, and fixes it to the connector joint through the external thread. When the pin needle body is damaged, only the damaged pin needle body can be replaced without replacing the entire connector joint. At the same time, when the pin needle body is inserted into the plastic socket of the target component, the inside of the plastic socket is squeezed by the limit block to prevent the pin needle body from loosening. Through the set air release groove, when the pin needle body is inserted into the plastic socket, the air in the plastic socket can be pressurized and discharged from the air release groove, thereby reducing the resistance encountered by the pin needle body when it is inserted.

[0006] Preferably, a plurality of limit blocks are evenly fixed on the outside of the pin needle body and are integrally formed with the pin needle body, and the limit blocks are located in the middle section of the pin needle body.

[0007] Preferably, first guiding surfaces are provided on both side surfaces of the limiting block in the vertical direction.

[0008] Preferably, second guiding surfaces are provided on both side surfaces of the limiting block in the transverse direction.

[0009] Preferably, one end of the air relief groove passes through the end of the pin needle body away from the external thread, and the other end terminates at the outside of the external thread, so that the gas in the plastic socket of the target component can be discharged from the air relief groove under the insertion and extrusion of the pin needle body, thereby facilitating the insertion of the pin needle body into the plastic socket. At the same time, the notch left by the air relief groove on the head of the pin needle body facilitates the external thread at the tail of the pin needle body to be screwed into the connector joint.

[0010] Preferably, the head of the pin body is round.

[0011] Preferably, a hollow groove is provided inside the pin body.

[0012] Compared with the traditional technology, the beneficial effects of the utility model are:

[0013] 1. By setting the pin needle body to a structure with an external thread at the tail, and fixing it to the connector joint through the external thread, when the pin needle body is damaged, only the damaged pin needle body can be replaced without replacing the entire connector joint. At the same time, when the pin needle body is inserted into the plastic socket of the target component, the inside of the plastic socket is squeezed by the limit block to prevent the pin needle body from loosening. By setting the air relief groove, when the pin needle body is inserted into the plastic socket, the air in the plastic socket can be pressurized and discharged from the air relief groove, thereby reducing the resistance encountered by the pin needle body when it is inserted.

[0014] 2. The notch left by the air relief groove on the head of the pin needle body increases the contact friction between the finger and the head of the pin needle body, making it easier to screw the external thread at the tail of the pin needle body into the connector joint.

[0021] 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.

[0022] Example:

[0023] See also Figure 1-Figure 5 The figure shows a pin needle structure for a new energy vehicle connector, including a connector joint 1 with a cable and a pin needle body 2. A plurality of pin needle bodies 2 are evenly distributed in the connector joint 1. The head of the pin needle body 2 is round, which is convenient for electrical contact with the target component. Limit blocks 3 are evenly arranged on the outside of the pin needle body 2. External threads 4 are arranged at the tail of the pin needle body 2. The pin needle body 2 is threadedly electrically connected to the metal threaded hole inside the connector joint 1 through the external threads 4. Air relief grooves 5 are evenly arranged on the outside of the pin needle body 2.

[0024] Some implementation methods of the present application are described in detail below with reference to the accompanying drawings:

[0025] See also Figure 1-Figure 5 By setting the pin needle body 2 as a structure with an external thread 4 at the tail, and fixing it to the connector joint 1 through the external thread 4, when the pin needle body 2 is damaged, only the damaged pin needle body 2 can be replaced, without replacing the entire connector joint 1. At the same time, when the pin needle body 2 is inserted into the plastic socket of the target component, the inside of the plastic socket is squeezed by the limit block 3 to prevent the pin needle body 2 from loosening. By setting the air relief groove 5, when the pin needle body 2 is inserted into the plastic socket, the air in the plastic socket can be pressurized and discharged from the air relief groove 5, thereby reducing the resistance encountered by the pin needle body 2 when it is inserted.

[0026] Among them, Figure 2 As shown, a plurality of limit blocks 3 are evenly fixed on the outside of the pin needle body 2 and are integrally formed with the pin needle body 2. The limit blocks 3 are located in the middle section of the pin needle body 2 and will not affect the electrical connection between the head of the pin needle body 2 and the target element.

[0027] At the same time, if Figure 3 As shown, first guide surfaces 6 are provided on both sides of the limit block 3 in the vertical direction to facilitate the limit block 3 to be inserted into the plastic socket of the target component. Figure 4As shown, second guide surfaces 7 are provided on both side surfaces of the limit block 3 in the transverse direction to prevent the limit block 3 from being broken or damaged when subjected to the circumferential rotation force of the pin needle body 2, thereby improving the connection strength between the limit block 3 and the pin needle body 2.

[0028] It is worth noting that Figure 2 As shown, one end of the vent groove 5 passes through the end of the pin needle body 2 away from the external thread 4, and the other end ends at the outside of the external thread 4, so that the gas in the plastic socket of the target component is discharged from the vent groove 5 under the insertion and extrusion of the pin needle body 2, thereby facilitating the pin needle body 2 to be inserted into the plastic socket. The notch left by the vent groove 5 at the head of the pin needle body 2 increases the contact friction between the finger and the head of the pin needle body 2, so that the external thread 4 at the tail of the pin needle body 2 is conveniently screwed into the connector joint 1.

[0029] In addition, if Figure 5 As shown, a hollow groove 8 is provided inside the pin needle body 2 , which can reduce the material cost of the pin needle body 2 .
