Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically a direct-insertion, highly stable circular electrical connector. Background Technology

[0002] Electrical connectors are accessories installed on circuit boards and various metal contacts. They mainly function to transmit power and signals, and can stably connect two sets of mechanisms. This provides physical support and prevents the connection from falling out of place. They also have thermal management functions to achieve the purpose of heat conduction and heat dissipation.

[0003] Electrical connectors are mostly round or square, and cannot be easily removed during installation. The distance between the two sides is also inconvenient to adjust, and the flow of current is also quite inconvenient. The entire connected equipment needs to be moved to remove these electrical connectors, which is quite inconvenient.

[0004] Now, a novel, high-stability, direct-insertion circular electrical connector is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a direct-insertion, highly stable circular electrical connector to solve the problem of inability to quickly disconnect and connect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a direct-insertion high-stability circular electrical connector, comprising a housing and a retaining ring, wherein the retaining ring is welded to the left side of the housing, and a sleeve block is fixed to the left side of the retaining ring, wherein the inner side of the sleeve block is provided with an internal threaded wall, a cylindrical body is sleeved between the retaining ring and the sleeve block, and a spiral pattern is provided on the left side surface of the cylindrical body, a nut is sleeved on the outside of the spiral pattern, and a fastening thread is provided on the inner wall of the nut, and a connecting cylinder is fixed to the left side of the cylindrical body.

[0007] As a further technical solution of this utility model, the fastening thread matches the helical pattern, and the nut can be rotated horizontally on the left side outside the cylinder.

[0008] As a further technical solution of this utility model, the cylinder can be embedded in the sleeve block and the fixing ring, and the internal threaded wall can be engaged with the spiral pattern.

[0009] As a further technical solution of this utility model, the surface of the fixing ring is provided with toothed blocks around its circumference, and the toothed blocks form a concave surface on the surface of the fixing ring.

[0010] As a further technical solution of this utility model, an assembly piece is fixed on the left side of the connecting cylinder, and slots are respectively provided at the four corners of the assembly piece. A left threaded cylinder is fixed at the center of the assembly piece, and a left toothed ring is fixed around the left side of the left threaded cylinder. A circular groove is provided laterally inside the left threaded cylinder, and a female needle core is installed in the circular groove.

[0011] As a further technical solution of this utility model, a right threaded cylinder is fixed on the right side of the outer shell, and a right toothed ring is fixed around the right side of the right threaded cylinder. A groove is provided horizontally inside the right threaded cylinder, and a female needle core is installed in the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this direct-insertion high-stability circular electrical connector not only makes it easy to disconnect or assemble the connector and increases the frictional resistance of the outer wall, but also makes it easy to install on both sides;

[0013] By attaching a nut to the outside of the spiral pattern, the cylinder is inserted laterally into the sleeve block. Then, the cylinder is rotated so that the right side of the spiral pattern on the surface is embedded in the sleeve block. The internal thread wall here engages with the side of the spiral pattern. Continue to rotate the nut to force the internal fastening thread to connect with the spiral pattern and press against the sleeve block, thus realizing the assembly of the two sides of the electrical connector. Disassembly is also the same, which can quickly connect or disconnect the circuit.

[0014] By setting teeth around the surface of the fixing ring, the surface teeth of the fixing ring can be pinched during installation, and the fingertips can be placed between the teeth and the concave surface to increase the frictional resistance between the fingers and the fixing ring. This prevents the fingers from slipping due to sweat when installing the structures on both sides of the connector, and also makes it easier to grip and apply force to rotate the fixing ring, helping people install electrical connectors. Sweaty fingers will not affect the manual installation of this device.

[0015] A left threaded cylinder is fixed at the center of the assembly piece, and a right threaded cylinder is fixed on the right side of the housing. The left threaded cylinder on the left is installed through the assembly piece with a slot, into which bolts or screws can be screwed. With the assistance of the left toothed ring, the female pin core one in the circular slot is inserted into the electrical appliance by screwing the left threaded cylinder. The right threaded cylinder on the right engages another electrical appliance with the right toothed ring, which facilitates the installation of the female pin core two and prevents the electrical connector from detaching from the electrical equipment.
