[0001] The utility model relates to the technical field of female connectors, in particular to a female connector. Background Art

[0002] The female connector is a universal connection device widely used in electronics, electrical appliances and instruments. It mainly plays the role of current or signal transmission. Since the specifications used in different electronic products are not exactly the same, there are many types of female connectors. According to the number of rows, there are single-row female connectors, double-row female connectors, triple-row female connectors, etc.; each row of female connectors consists of multiple side-by-side terminals.

[0003] The female connector is generally composed of a shell and terminals. The terminals are fixed in the shell, and the bottom of the terminals extend out. The bottom of the terminals are generally connected to the connection holes on the circuit board or other equipment, and the jacks on the top are connected to the wiring harness for current or signal transmission.

[0004] However, the existing female connectors are not firmly fixed between the terminals and the shell. During operation, especially in vibration scenarios and when working for a long time, the terminals and the shell are prone to shaking or even falling off, which can lead to poor contact or even the risk of failure to work, reducing the stability of operation.

[0005] In view of this, we propose a female connector. Utility Model Content

[0028] Example:

[0029] Reference Figure 1-Figure 6 A female connector comprises a shell 1 and a terminal 3, wherein a fixing hole 103 is provided at the bottom of the shell 1; the terminal 3 consists of a connecting tube 301 and a plug pin 304; the connecting tube 301 is inserted into the fixing hole 103, and the side wall of the connecting tube 301 is in contact with the fixing hole 103. When the connecting tube 301 is inserted into the fixing hole 103, an adhesive is applied to the outer wall of the connecting tube 301 as needed. After the connecting tube 301 is inserted, the connecting tube 301 is better connected to the inside of the fixing hole 103 to avoid shaking. The plug pin 304 is fixed to the bottom of the connecting tube 301; a socket 101 is provided at the top of the shell 1, and the socket 101 is connected to the top of the fixing hole 103. The plug pin 304 is used to connect with the connecting hole on a circuit board or other equipment. The wiring harness interface is inserted into the connecting tube 301 through the socket 101, and then contacts the inner wall of the connecting tube 301 to realize the connection of the circuit or signal.

[0030] During the working process, the side wall of the connecting tube 301 is attached to the fixing hole 103, and the fixing hole 103 plays a restraining role to limit the shaking of the connecting tube 301, thereby avoiding shaking or even falling off between the terminal 3 and the housing 1 in a vibration scenario, thereby ensuring stability during operation.

[0031] like Figure 1 , Figure 4-Figure 6 A clamping block 303 is fixedly connected to the side wall of the connecting cylinder 301 . The clamping block 303 is integrally formed with the connecting cylinder 301 . A first clamping groove 2 is provided on the side wall of the housing 1 . The clamping block 303 is clamped in the first clamping groove 2 .

[0032] like Figure 4When the connecting tube 301 is inserted into the fixing hole 103, the block 303 is compressed and deformed during the contact with the inner wall of the fixing hole 103. When the connecting tube 301 is fully inserted into the fixing hole 103, the block 303 moves to the first slot 2. At this time, the block 303 is out of contact with the inner wall of the fixing hole 103, and then the shape is restored to the initial state. At this time, the block 303 is stuck in the first slot 2 to achieve the purpose of self-locking, avoid the terminal 3 from accidentally falling off when working for a long time in a vibration scene, and improve stability.

[0033] A through slot 4 is disposed on the side wall of the connecting tube 301. The through slot 4 is symmetrically designed. The through slot 4 can improve the heat dissipation effect and avoid excessive temperature during operation.

[0034] An elastic plate 302 is fixedly connected to the top of the through slot 4 ; the elastic plate 302 is located in the through slot 4 , and the elastic plate 302 is inclined toward the inner side of the connecting tube 301 .

[0035] Since the through slot 4 is symmetrically designed, there are two elastic plates 302 , both of which are inclined toward the inside of the connecting tube 301 , also symmetrically designed.

[0036] Since the elastic plate 302 is inclined toward the inside of the connecting tube 301 , when the wiring harness interface is inserted into the connecting tube 301 through the jack 101 , the elastic plate 302 and the wiring harness interface are tightly attached to improve the stability of the connection between the wiring harness and the terminal 3 .

[0037] The connecting tube 301 , the elastic plate 302 , the clamping block 303 , and the plug pin 304 are all integrally formed, and are all made of elastic conductive material.

[0038] A second slot 201 is provided at the bottom of the housing 1. When the connecting tube 301 is plugged into the fixing hole 103, the pin 304 is stuck in the second slot 201. The second slot 201 can limit the pin 304 and prevent the connecting tube 301 from rotating in the fixing hole 103.

[0039] The housing 1 is provided with a gap groove 102 , and the width of the gap groove 102 is between 0.2-0.5 cm. External air can enter the housing 1 through the gap groove 102 , thereby improving the heat dissipation effect.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
