Problems solved by technology

Because its connecting end is an extruded sheet structure, the cross-section of the product is relatively small, the extrusion deformation is small, and the resistivity is large, which makes its internal resistance and contact resistance large, which is not enough to carry the large current of high-power equipment.

Embodiment

[0033] Example: see Figure 1-8 , a safe high-power, high-current, and high-voltage-resistant composite electrical connector in the figure is characterized by: including a conductive connection component and an insulating protective sleeve, the conductive connection component includes a conductive connection male head, a conductive connection female head, and a locking Bolt; one end of the conductive connection male head is a cylindrical welding cup, which is used for cable welding, and the other end is a trapezoidal chuck extending in the longitudinal section along the axial direction. The upper and lower surfaces of the chuck have an included angle with the central axis; The thickness of the outer end of the head is greater than the thickness of the root. One end of the conductive connection female head is a cylindrical welding cup, which is used for cable welding, and the other end is two clamps protruding axially and located on both sides of the axis. The shape of the area...

Abstract

The invention discloses a safety-type large-power, large-current and high-voltage-resistant composite electrical connector, and the connector comprises a conductive connection module and insulating protection bushings, wherein the conductive connection module comprises a conductive connection male head, a conductive connection female head, and a locking bolt. The conductive connection male head and the conductive connection female head are in holding-on connection, and are fastened through the locking bolt. The two insulating protection bushings are arranged symmetrically, and respectively sleeve the tail parts of the male head and the female head. When the bolt of the connector is screwed up, the inclined surfaces of two sides of a clamping head are pressed to slide oppositely, and plastic deformation is aroused. Not only are the upper and lower surfaces pressed, but also the inner end face and the outer end face are pressed. A rough line in a specific reference map represents a conductive junction surface, and the conductive junction surface enables the surface contact to be more complete, thereby reducing the contact impedance, and improving the current conducting capability.

Description

technical field [0001] The invention relates to the technical field of connecting terminals in electrical circuits, in particular to a safe high-power, high-current, high-voltage-resistant composite electrical connector. Background technique [0002] At present, most of the connectors used in the electrical industry are sheet-shaped cold-pressed joints or solder cup joints, and most of them are made of electroplated carbon steel or brass. Because its connecting end is an extruded sheet structure, the cross section of the product is relatively small, the extrusion deformation is small, and the resistivity is large, which makes its internal resistance and contact resistance large, which is not enough to carry the high current of high-power equipment. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to propose a safe high-power, high-current, high-voltage resistant composite electrical connector. [0004] The tec...
