Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a small-size and large-current wire-end connector. Background Art

[0002] A connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: it acts as a communication bridge between a blocked or isolated circuit in a circuit, enabling current to flow and the circuit to achieve its intended function. Connectors are indispensable components in electronic devices. Looking along the path of current flow, you will always find one or more connectors. The forms and structures of connectors are ever-changing. With different application objects, frequencies, powers, application environments, etc., there are various forms of connectors. For example, the connectors used for lighting on a football field, the connectors for hard disk drives, and the connectors for igniting rockets are very different. However, no matter what kind of connector, it is necessary to ensure the smooth, continuous, and reliable flow of current. Generally speaking, what a connector connects is not limited to current. Today, with the rapid development of optoelectronic technology, in an optical fiber system, the carrier for transmitting signals is light, and glass and plastic replace the wires in an ordinary circuit. However, connectors are also used in the optical signal path, and their functions are the same as those of circuit connectors. There are already many connectors with different functions in the prior art. For example, the patent document with the publication number CN216055463U discloses a wire-end connector and a connector assembly. The wire-end connector includes a connector housing and at least one wire-end body. At least one through groove is provided on the connector housing, and each wire-end body is inserted into a through groove and extends forward. The wire-end body includes a conductive part for electrically connecting with a docking connector; a first docking part is provided at the front end of the connector housing. When the wire-end body is docked with the docking connector, the first docking part is adaptively connected with the docking connector. The wire-end connector involved in the utility model can be connected with the docking connector through the cooperation of the first docking part, so that it is not necessary to manually align the wire-end connector and insert it into the docking connector, thus having the function of automatic blind plugging and guiding, which is convenient to use.

[0003] However, when the connector in the prior art is in use, the wiring head cannot be quickly disassembled and separated. At the same time, the lengths of its positive and negative poles are the same, and they will contact the connector body simultaneously, resulting in poor safety. Therefore, this application aims to provide a small-size and large-current wire-end connector that can overcome the above defects. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a small-size and large-current wire-end connector.

[0005] The object of the present utility model is achieved by the following technical solutions: A small-size large-current wire-end connector includes a wire-end female head, a first wiring terminal, a second wiring terminal, and a panel. The first wiring terminal and the second wiring terminal are connected to the wire-end female head. The panel is provided with a clamping hole having the same cross-sectional shape as that of the wire-end female head, and the wire-end female head can pass through the clamping hole. Wherein, when the wire-end female head is nested in the clamping hole, the wire-end female head and the panel can move relative to each other.

[0006] Preferably, a slider mounting seat is provided on the wire-end female head, and a slider is provided in the slider mounting seat. Wherein, when the slider slides, the slider can pass through the clamping hole and abut against the wire-end female head.

[0007] Preferably, an elastic hook is provided on the slider, and a clamping groove is provided on the slider mounting seat, and the elastic hook can be embedded in the clamping groove.

[0008] Preferably, the first wiring terminal includes a first contact portion and a first wire welding portion, and the first contact portion can be clamped to the first wire welding portion.

[0009] Preferably, the second wiring terminal includes a second contact portion and a second wire welding portion, and the second contact portion can be clamped to the second wire welding portion.

[0010] Preferably, the length of the first contact portion is less than the length of the second contact portion, and heat shrinkable tubes are sleeved on both the first wire welding portion and the second wire welding portion.

[0011] Preferably, a first clamping block and a second clamping block are provided on the wire-end female head to define a limiting groove, and the panel can be nested in the limiting groove.

[0012] The present utility model has the following advantages:

[0013] (1) During actual use, the wire-end female head and the panel are detachably connected, which is convenient for disassembly and maintenance. When it is necessary to separate the wire-end female head and the panel, only need to move the slider backward so that the slider exits the clamping hole, and then the wire-end female head can be moved horizontally. After the wire-end female head is completely aligned with the clamping hole, it can be withdrawn from the clamping hole. Through the above setting method, the quick disassembly or installation of the wire-end female head and the panel can be achieved conveniently.

[0014] (2) Through the mutual clamping of the elastic hook and the clamping groove, the movement of the slider can be restricted, thereby ensuring that the position of the clamping block can be fixed during use.

[0015] (3) The only difference between the first terminal and the second terminal lies in the different lengths of their wiring parts, while the rest of the structures are the same. The first terminal can be the negative terminal, and the second terminal can be the positive terminal. When wiring, the first terminal and the second terminal can contact the mating male terminal in sequence according to the time sequence, thereby increasing the safety during use.

[0016] (4) The first clamping block and the second clamping block can clamp the panel, thereby further improving the position stability of the panel during use. Brief Description of the Drawings
