[0002] Electrical connectors are widely used in electronic devices to achieve conductive connections between circuits. Existing electrical connectors often have the following problems during use: some connectors use plug-in connections, which lack connection stability and are prone to loosening due to vibration or other factors; the heat dissipation performance of the connection points is poor, and long-term use can lead to heat accumulation that affects conductivity and even damages components; some connectors are also not easy to install and remove, causing inconvenience in use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rotary snap-fit ​​electrical connector. By setting a rotary snap-fit ​​structure for the female connector assembly and the male connector assembly, as well as a heat dissipation hole structure, it solves the problems of insufficient connection stability, poor heat dissipation, and inconvenient assembly and disassembly of existing electrical connectors.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotary snap-fit ​​electrical connector, comprising a female connector assembly and a male connector assembly arranged in combination. The female connector assembly includes a female connector seat, one end of which is provided with a pin connector for connection to an external circuit, and the other end of which is provided with a recessed fitting portion. The male connector assembly includes a male connector seat, one end of which is provided with an inner protrusion adapted to the recessed fitting portion for easy insertion into the recessed fitting portion to achieve initial positioning. The other end of the male connector seat is connected to a connecting wire for circuit conduction.

[0007] As a further improvement of this utility model: the concave fitting portion is provided with a first copper connector contact and a second copper connector contact for realizing conductive connection of different circuits; at least one rotating locking block is provided circumferentially on the outer side of the female connector seat to provide a structural basis for rotating locking; and a first heat dissipation hole is provided on the female connector seat to dissipate heat from the female connector assembly; the inner protrusion is provided with a first copper connector spring that contacts and cooperates with the first copper connector contact and a second copper connector spring that contacts and cooperates with the second copper connector contact, ensuring the stability of conductive contact. For reliability, the male connector seat has an L-shaped rotating locking groove on its inner side that is adapted to the rotating locking block. By rotating, the rotating locking block can be engaged and fixed with the L-shaped rotating locking groove. The male connector seat also has a second heat dissipation hole to dissipate heat from the male connector assembly. When the inner protrusion is embedded in the inner recess, the rotating locking block can be locked into the L-shaped rotating locking groove and fixed by rotation, improving the stability of the connection. Furthermore, the first copper connector contact is in contact with the first copper connector spring and conducts electricity, and the second copper connector contact is in contact with the second copper connector spring and conducts electricity, achieving stable circuit conduction.

[0008] As a further improvement of this utility model: there are multiple first heat dissipation holes, and the multiple first heat dissipation holes are evenly distributed circumferentially on the side wall of the female connector seat. The evenly distributed first heat dissipation holes can dissipate the heat inside the female connector seat more efficiently and evenly.

[0009] As a further improvement of this utility model, the male connector assembly also includes reinforcing blocks. The reinforcing blocks are multiple and are arranged at equal angles around the male connector seat. The reinforcing blocks are used to enhance the structural strength of the connection between the male connector seat and the connecting wire, and to prevent the part from being damaged by stress during long-term use.

[0010] As a further improvement of this utility model: the number of the rotating blocks is two and the other end is provided with a chamfer. The two rotating blocks are symmetrically arranged on the outside of the female connector seat. The chamfer makes it easy for the rotating blocks to be smoothly inserted into the L-shaped rotating locking groove. The two symmetrically arranged rotating blocks make the locking more balanced and stable.

[0011] As a further improvement of this utility model: the number of L-shaped rotating snap-fit ​​slots is two, and one end of the opening is provided with a chamfer. The two L-shaped rotating snap-fit ​​slots are symmetrically arranged on the inner side of the male connector seat. The chamfer at the opening matches the chamfer of the rotating snap-fit ​​block, which further improves the guiding and smoothness during snap-fit.

[0012] As a further improvement of this utility model: there are multiple first copper connector contacts and multiple second copper connector contacts, and the multiple first copper connector contacts and multiple second copper connector contacts are alternately distributed in the concave fitting portion; the number of first copper connector springs and the number of second copper connector springs correspond one-to-one with the number of first copper connector contacts and the number of second copper connector contacts, and the multiple sets of alternately distributed conductive structures can simultaneously realize the conduction of multiple circuits, thereby improving the applicability and conductivity efficiency of the electrical connector.

[0013] As a further improvement of this utility model: both the first heat dissipation hole and the second heat dissipation hole are elongated holes. The structure of the elongated holes not only ensures the heat dissipation area, but also maintains the structural strength of the connector seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1.

The first copper connector contact 14 is in contact with the first copper connector spring 24 and conducts electricity, and the second copper connector contact 15 is in contact with the second copper connector spring 25 and conducts electricity, realizing stable circuit conduction.

[0027] There are multiple first heat dissipation holes 17, and the multiple first heat dissipation holes 17 are evenly distributed circumferentially on the side wall of the female connector seat 11. The evenly distributed first heat dissipation holes 17 can dissipate the heat inside the female connector seat 11 more efficiently and evenly.

[0028] The male connector assembly 2 also includes reinforcing blocks 28. Multiple reinforcing blocks 28 are arranged at equal angles around the male connector seat 21. The reinforcing blocks 28 are used to enhance the structural strength of the connection between the male connector seat 21 and the connecting wire 22, so as to prevent the part from being damaged by stress during long-term use.

[0029] There are two rotating locking blocks 16, and the other end is chamfered. The two rotating locking blocks 16 are symmetrically arranged on the outside of the female connector seat 11. The chamfer makes it easy for the rotating locking blocks 16 to be smoothly inserted into the L-shaped rotating locking groove 26.

At this time, the rotating locking block 16 is aligned with the opening of the L-shaped rotating locking groove 26. After insertion, the male connector assembly 2 or the female connector assembly 1 is rotated so that the rotating locking block 16 rotates and locks in the L-shaped rotating locking groove 26. At the same time, the first copper connector contact 14 contacts the first copper connector spring 24, and the second copper connector contact 15 contacts the second copper connector spring 25, so as to realize the circuit conduction. During use, the first heat dissipation hole 17 and the second heat dissipation hole 27 can dissipate the heat of the connection part.
