[0003] Currently, during the assembly of an electrical connector, it is usually necessary to plug the male and female connectors of the connector so that the terminals on the male and female connectors contact each other to achieve assembly of the electrical connector.

[0004] However, during actual use, the male and female heads of the connector may become loose and fall off due to some external factors, especially in mobile devices or in harsh working environments. Factors such as vibration, excessive impact, temperature changes (connector plastic expands and contracts due to heat), etc. may cause the installed male and female heads of the connector to gradually loosen, making the metal terminals inside the connector unable to effectively contact, resulting in unstable or interrupted current transmission, thereby affecting the stable operation of the electronic equipment. In addition, poor contact will increase resistance, thereby generating additional heat at the metal contact points, which may cause local temperatures to be too high, thereby increasing the risk of overheating and damage to the connector. Therefore, in order to solve the above-mentioned problems, an electrical connector is provided. Utility Model Content

[0032] Specifically, during use, the male head 1 and the female head 2 can be fixed after being plugged in by using the buckle sleeve 5, the buckle hole 6, the buckle 7 and the elastic part, which greatly improves the connection stability of the male head 1 and the female head 2, and prevents the male head 1 and the female head 2 from loosening and falling off due to external factors, thereby ensuring that the male terminal 3 and the female terminal 4 can be effectively in contact, which not only reduces the risk of damage to the electrical connector, but also ensures the stable operation of the electronic equipment.

[0033] The elastic member includes an elastic sheet 71 fixedly connected to the female connector 2 , a pressing block 72 fixedly connected to the elastic sheet 71 , and the buckle 7 fixedly connected to the elastic sheet 71 .

[0034] Specifically, the pressing block 72 of the elastic sheet 71 cooperates to elastically support the buckle 7 so that the buckle 7 can be tightly buckled in the buckle hole 6 .

[0035] Two limiting frames 73 are fixedly connected to the female connector 2 , and the elastic piece 71 is pressed against the surface of the limiting frames 73 by its own elastic force.

[0036] Specifically, the movable range of the elastic piece 71 can be limited by the provision of the limiting frame 73 .

[0037] A positioning groove 31 is provided on the male connector 1 , and a positioning head 32 is fixedly connected to the male terminal 3 . When the male terminal 3 is installed on the male connector 1 , the positioning head 32 is inserted into the positioning groove 31 .

[0038] Specifically, by providing the positioning groove 31 and the positioning head 32 , the male terminal 3 can be positioned, thereby ensuring the flatness and consistency of the male terminal 3 .

[0039] A welding foot 33 is fixedly connected to the male terminal 3 , and the welding foot 33 and the male terminal 3 are integrally formed.

[0040] Specifically, by providing the soldering feet 33 , it is possible to facilitate soldering the connector to the circuit board, thereby achieving a stable connection between the connector and the circuit board.

[0041] An elastic undercut 42 is fixedly connected to the female terminal 4 . When the female terminal 4 is mounted on the female connector 2 , the elastic undercut 42 is snapped into the female connector 2 .

[0042] Specifically, by providing the elastic undercut 42 , the female terminal 4 can be further clamped in the female connector 2 , thereby improving the stability of the female terminal 4 .

[0043] A terminal head 41 is fixedly connected to the female terminal 4 , and the terminal head 41 and the female terminal 4 are integrally formed.

[0044] Specifically, through the setting of the terminal head 41, the female terminal 4 can be supported to prevent the two spring clips on the female terminal 4 from pressing against the inner wall of the female head 2, thereby ensuring the normal elasticity of the spring clips, so that the two spring clips on the female terminal 4 can stably clamp the male terminal 3.

[0045] An anti-mistake groove 8 is provided inside the male connector 1 , and an anti-mistake protrusion 9 is fixedly connected to the female connector 2 . When the male connector 1 and the female connector 2 are plugged in, the anti-mistake protrusion 9 is plugged into the anti-mistake groove 8 .

[0046] Specifically, by providing the anti-mistake groove 8 and the anti-mistake protrusion 9, it is possible to ensure that the male connector 1 and the female connector 2 are correctly plugged in, thereby preventing the male connector 1 and the female connector 2 from being connected in the wrong direction.

[0048] Specifically, the provision of the card slot 10 and the fixed terminal 11 can further improve the connection stability between the male connector 1 and the circuit board, thereby increasing the connection strength between the two.

[0049] One side of the buckle 7 is designed as a bevel.

[0050] Specifically, such a design enables the buckle 7 to quickly slide across the surface of the buckle sleeve 5, thereby facilitating the quick connection between the buckle 7 and the buckle hole 6.

[0051] Working principle: During the use of this electrical connector, when the male head 1 and the female head 2 are plugged in and assembled, the buckle 7 is squeezed against the buckle sleeve 5, and at the same time, the inclined surface of the buckle 7 will slide over the surface of the buckle sleeve 5 and bend the elastic sheet 71. When the buckle 7 slides to the buckle hole 6, the elastic force of the elastic sheet 71 resets the buckle 7 and buckles it into the buckle hole 6, thereby completing the assembly and fixation of the male head 1 and the female head 2. When the male head 1 and the female head 2 are separated, the pressing block 72 can be pressed and the elastic sheet 71 can be bent to disengage the buckle 7 from the buckle hole 6, thereby releasing the fixation of the male head 1 and the female head 2, and then the male head 1 and the female head 2 can be separated by applying force.

[0052] This electrical connector, through the coordinated use of the buckle sleeve 5, the buckle hole 6, the elastic sheet 71 and the snap 7, can fix the male head 1 and the female head 2 after insertion, greatly improving the connection stability of the male head 1 and the female head 2, preventing the male head 1 and the female head 2 from loosening and falling off due to external factors, and thus ensuring that the male terminal 3 and the female terminal 4 can effectively contact each other, which not only reduces the risk of damage to the electrical connector, but also ensures the stable operation of the electronic equipment.

[0053] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
