Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a high-power connector. Background Technology

[0002] High-power connectors are used to transmit high-current / high-voltage electrical energy between devices or modules. Typical operating currents range from tens to hundreds of amperes, and rated voltages can reach hundreds or even thousands of volts. They are widely used in high-voltage systems for new energy vehicles, energy storage and photovoltaic inverters, data center power distribution, industrial servos, and rail transportation.

[0003] The aforementioned existing technical solutions have the following drawbacks: existing high-power connectors are prone to water / dust ingress channels due to assembly deviations; salt spray and chemical media can accelerate the electrochemical corrosion of terminals and shielding braids. The crimping quality of large cross-sectional area cables is highly dependent on process and tool control; the tensile strength, void ratio, and dimensional consistency of field terminations are difficult to guarantee, resulting in high rework costs. Utility Model Content

[0004] The purpose of this invention is to provide a high-power connector to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-power connector includes an insulating shell, a plug conductive core, insulating partitions, and a base. The top of the insulating shell is completely open. Multiple plug conductive cores are fixedly installed in the middle of the insulating shell, and the axes of the plug conductive cores are all vertically arranged. Multiple insulating partitions are evenly arranged at both ends of the insulating shell, and the axes of the insulating partitions are arranged front and back. There are gaps between the front and rear faces of the insulating partitions and the front and rear faces of the insulating shell. A base is fixedly installed between the insulating partitions. The top of the base has a through hole that extends vertically, and the axis of the through hole is vertically arranged. A terminal block is fixedly installed in the through hole.

[0006] By adopting the above technical solution, the fully open design of the top of the insulating shell, together with the gap between the front and rear faces of the insulating partition and the inner wall of the insulating shell, creates a smooth air convection channel. The vertical axis of the plug's conductive core forms a reasonable spatial layout with the insulating partitions arranged before and after the axis.

[0007] In a further embodiment, the terminal block is composed of a first straight edge, a second straight edge, a third straight edge, a fourth straight edge, a fifth straight edge, a sixth straight edge, and a metal block. The first straight edge, the second straight edge, and the third straight edge are integrally formed to form a first spring, and the fourth straight edge, the fifth straight edge, and the sixth straight edge are integrally formed to form a second spring. The bottom of the first straight edge and the top of the second straight edge are fixedly installed on the left side of the metal block. The other end of the second straight edge extends to the bottom of the base. The bottom of the fourth straight edge and the top of the fifth straight edge are fixedly installed on the right side of the metal block. The fifth straight edge extends to the bottom of the base. There is a gap between the first spring and the second spring.

[0008] By adopting the above technical solution, after the bottom ends of the first and second springs are squeezed into the socket by external force, they will move outward under the action of the second straight edge / fifth straight edge in order to restore their free state. Since the position of the conductive sheet inside the socket is unknown, this structure allows it to make good contact with the conductive sheet inside the socket after entering and exiting the socket, thus achieving the effect of conducting electricity.

[0009] In a further embodiment, the top of the second straight edge is the first straight edge, the bottom of the second straight edge is the third straight edge, the top of the fifth straight edge is the fourth straight edge, and the bottom of the fifth straight edge is the sixth straight edge. The top of the first straight edge and the fourth straight edge are parallel to each other. The straight-line distance between the top of the second straight edge and the top of the fifth straight edge is greater than the distance between the bottom of the second straight edge and the bottom of the fifth straight edge. The straight-line distance between the top of the third straight edge and the top of the sixth straight edge is less than the distance between the bottom of the third straight edge and the bottom of the sixth straight edge.

[0010] By adopting the above technical solutions and designing the distance relationship between these straight edges, and by rationally planning the spatial dimensions, the overall structure can achieve a better balance in terms of stability, load-bearing capacity, space utilization, and the precision of cooperation with other components, thus better meeting the requirements for electrical conductivity.

[0011] In a further embodiment, the top of the first straight edge and the fourth straight edge are each provided with an integrally formed ejector pin, the bottom of the ejector pin is provided with a blunt structure, and the bottom of the third straight edge and the sixth straight edge are each provided with a blunt structure.

[0012] By adopting the above technical solution, the terminal block can be better inserted into the socket. In a further embodiment, the insulating housing is provided with integrally formed rectangular protrusions on both the left and right sides, and the top of the rectangular protrusions is provided with a first mounting hole and a second mounting hole.

[0013] By adopting the above technical solution, assembly becomes more convenient and tighter, and dust is effectively blocked.

[0014] In a further embodiment, the front and rear end faces of the insulating shell are provided with multiple rectangular grooves, the axis of the rectangular grooves is vertically arranged, and the upper and lower end faces of the rectangular grooves are completely open.

[0015] By adopting the above technical solution, the rectangular groove design can achieve an aesthetic effect and increase friction during installation.

[0016] In summary, this utility model has the following beneficial effects: 1. The arrangement of the first spring, the second spring, and the metal block achieves better contact conductivity. 2. The design of the first and second mounting holes facilitates assembly. 3. By using multiple conductive cores in the plug, higher power can be achieved. Attached Figure Description
