Technical Field
[0001] This utility model relates to the field of through-hole power connector technology, and in particular to a through-hole power connector structure. Background Technology
[0002] A through-hole power connector is a common type of power connector. Its structure mainly includes the following key components: Pin and socket structure: This is the most basic structure of the connector. The pins are typically fixed to the circuit board, while the socket is fixed to the cable. The contact surfaces between the pins and socket need to maintain a good electrical connection to ensure the normal operation of the circuit. The shape and size of the pins and socket can be designed according to different applications. Housing structure: The connector housing is usually made of plastic or metal, and its main function is to protect the pins and socket, as well as to secure the connector. The shape and size of the housing can also be designed according to different applications, such as through-hole connectors, panel connectors, and wire harness connectors.
[0003] An existing type of direct-plug power connector structure is prone to problems when used by operators, as the insertion and extraction force is largely unaffected by ambient temperature. This can affect the ease of operation and installation stability when connecting and fixing the equipment. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a direct-insertion power connector structure.
[0005] This utility model is achieved using the following technical solution: a direct-insertion power connector structure, including a female terminal and an anti-slip protrusion, a female end shell is inserted into the surface of the female terminal, a female end rubber dust cap is threaded to the rear end of the female end shell, a sealing ring is inserted inside the female end rubber dust cap, a male end positioning member is inserted to the rear end of the female end rubber dust cap, a male end terminal is inserted inside the male end positioning member, a male end shell is threaded to the rear end of the male end positioning member, and a male end wire is fixedly connected to the rear end of the female end terminal of the male end shell.
[0006] Through the above technical solution, the rear end of the female end shell is threaded with a female end rubber dust cap, and a sealing ring is inserted inside the female end rubber dust cap, which can effectively prevent dust and moisture from entering the connector and protect the internal components from contamination and corrosion. The sealing ring is located inside the female end shell, and its front surface contacts the rear end of the female end terminal. This tight contact design further enhances the sealing effect and ensures the reliability of the connector in harsh environments.
[0007] As a further improvement to the above solution, the rear end of the female terminal contacts the front surface of the sealing ring, and the sealing ring is located inside the female terminal housing.
[0008] As a further improvement to the above solution, the male terminal is located at the rear end of the female rubber dust cap, and the male terminal is located at the rear end of the sealing ring.
[0009] With the above technical solution, the female terminal is fitted with a female outer shell, and the male terminal is inserted into the inside of the female rubber dust cap and located at the rear end of the sealing ring, so that the female terminal and the male terminal can make close contact and ensure the stability of the electrical connection.
[0010] As a further improvement to the above solution, the male end shell is located at the rear end of the female end rubber dust cap, and the male end positioning component is located at the rear end of the female end shell.
[0011] With the above technical solution, the male end positioning component is located at the rear end of the female end shell. This design allows the male end terminal to be smoothly inserted into the female end rubber dust cap, achieving a stable connection.
[0012] As a further improvement to the above solution, the male terminal is inserted into the inside of the female rubber dust cap, and the male terminal is provided inside the sealing ring.
[0013] As a further improvement to the above solution, the number of anti-slip bumps is set to several, and the several anti-slip bumps are symmetrically distributed on the left and right sides with the male end shell as the center.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model consists of two parts: a male end and a female end. Both the male and female ends are made of rigid plastic, and the insertion and extraction force is basically unaffected by the ambient temperature. The male and female ends have a structure to prevent mistaken insertion when mating, which can meet the requirements of blind insertion. This product adds a groove to the head of the male end and inserts a sealing ring. The interference force between the male and female ends is large, which can ensure the IP67 waterproof effect and occupy a small space. The female end is a plate end, and the product uses a large-sized gold-plated machined terminal inside. When in use, the female end is fixed and the male end can be directly inserted and removed. The head of the female end is designed with a dust cap, which is connected to the sealing gasket for protection when not in use.
[0016] This invention provides a good anti-slip effect by setting a number of anti-slip protrusions symmetrically distributed around the male end shell. This makes it easier for users to apply force when plugging and unplugging the connector, reducing operational errors caused by slipping hands. The symmetrically distributed anti-slip protrusions enhance the convenience of operation. The male end positioning component has a male end terminal inserted inside and a male end shell threaded to the rear end. The male end positioning component can ensure the accurate positioning of the male end terminal during the plugging process and prevent poor contact caused by misalignment.
