Electrical connector plug housing

Abstract

This utility model discloses an electrical connector plug housing. The base of the base is formed with a pair of cylinders. The sides of the arc-shaped plates extending from the cylinders are provided with protrusions. The front of the cylinder port is connected to an arc-shaped profile plate with a notch. The rear of the ring extends a baffle. The arc-shaped plates of the cylinders are fixed to the profile plate and the ring by the protrusions. The baffle extending from the ring blocks the electrical busbar placed inside the cylinder, so that the plug electrical busbar that is not connected to the socket terminal is fixed, preventing the electrical busbar from detaching from the base before connection. This facilitates the smooth connection of the electrical busbar and improves the success rate of electrical busbar connection.

Description

Technical Field

[0001] This utility model relates to connectors between vehicle-mounted devices, and in particular to the plug of an electrical connector. Background Technology

[0002] Electrical connectors inside electric vehicles are used to achieve electrical connections between batteries, chargers, charging ports, and electrical devices, as well as between circuit control equipment and electrical components. Most electrical connectors use a combination of cables, busbars, and terminals for their input and output conductors, depending on the connection requirements of various devices. The connection methods for the input and output conductors of electrical connectors fall into two categories: one is connection within a single housing, and the other is connection within a male and female housing. Electrical connectors using the male-female connection method are divided into plugs and sockets. For example, in the connectors disclosed in Chinese patent documents CN222463652U and CN221928780U, the copper busbar passes through the cable mounting cavity and is assembled within the bolt mounting cavity. Before the copper busbar is connected to the copper post, if the wire is pulled, it will pull the copper busbar, causing it to detach from the cable mounting cavity and affecting the connection operation of the electrical connector. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art where connection operations fail due to accidental detachment of the copper busbar, this utility model proposes an electrical connector plug housing that pre-fixes the busbar to achieve smooth connection operations and improve the connection success rate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an electrical connector plug housing, comprising a base, a pair of cylinders formed at the base of the base, the cylinders extending into arc plates, the sides of the arc plates being provided with protrusions; a ring is provided at the port of the cylinder, the front part of the ring is connected to an arc-shaped profile plate, the profile plate having a notch for accommodating the protrusions, and a baffle extending from the rear part of the ring.

[0005] Compared with the prior art, the beneficial effects of this utility model are as follows: Since the arc plate of the cylinder is fixed by the protrusions to the profile plate and its ring, and the baffle extending from the ring blocks the electric busbar placed inside the cylinder, the plug electric busbar that is not connected to the socket terminal is fixed, preventing the electric busbar from detaching from the base before the terminal is connected, which is conducive to the smooth connection of the electric busbar and improves the success rate of the electric busbar connection. Since the electric busbar is pre-fixed by the arc profile plate, the center of the connection hole of the electric busbar is aligned with the cylinder, improving the accuracy of the connection between the electric busbar and the terminal.

Each cylinder 1.5 extends into an arcuate piece 1.8, with an angle ranging from 10 to 30 degrees. A protrusion 1.7 is provided on the outer surface of the arcuate piece 1.8. The cylinders 1.5 are fixed to the clamp 4 via the protrusion 1.7. The clamp 4 comprises a ring 4.1, an arcuate profile plate 4.3, and a baffle 4.4. The ring 4.1 is located at the port of the cylinder 1.5. The outer wall radii of the pair of rings 4.1 are the same as and concentric with the inner wall radii of the cylinders 1.5. The rings 4.1 connect to the arcuate profile plates 4.3, which are spaced apart. The inner wall radius of the arcuate profile plates 4.3 is the same as and concentric with the outer wall radius of the cylinders 1.5. A notch 4.5 is provided in the middle of the arcuate profile plates 4.3. The arc-shaped profile plate 4.3 is located at the front (front side) of the ring 4.1, and the rear (rear end face) of the ring 4.1 extends to the baffle 4.4. The ring 4.1 of the hoop 4 is inserted into the cylinder 1.5, and the arc-shaped piece 1.8 of the cylinder 1.5 is inserted between the ring 4.1 and the arc-shaped profile plate 4.3. The notch 4.6 extends past the protrusion 1.7 of the cylinder 1.5, and the protrusion 1.7 fixes the hoop 4. The arc-shaped profile plate 4.5 clamps the arc-shaped piece 1.8. The fixed hoop 4 blocks the head 2.1 of the busbar 2 through the baffle 4.4, so that the busbar 2 can be fixed and will not detach from the base 1.

[0014] like Figures 3 to 6 As shown, the electrical connector plug consists of a base 1, an electrical busbar 2, a cable 3, a clamp 4, a main bolt 5, and a cover 11. The base 1 is integrally molded and consists of a base 1.1, an outer shell 1.2, a housing 1.3, and an inner shell 1.4. The base 1.1 extends to the outer shell 1.2, the housing 1.3, and the inner shell 1.4. The outer shell 1.2 and the inner shell 1.4 are arranged at a 90-degree angle to the housing 1.3.
