Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage connectors, in particular to a finger-touch-proof high-voltage connector. Background Art

[0002] High-voltage connector is an important electrical component, mainly used for the transmission and distribution of high-voltage electric energy. It has the characteristics of high voltage and large current. The high-voltage connector realizes the transmission of high-voltage electric energy through the insertion of the plug and the socket. In the inserted state, a conductive channel is formed between the contacts. When the current passes through the contacts, a certain resistance will be generated, but the voltage drop is very small, ensuring the stable transmission of electric energy. At the same time, the role of the insulating part ensures the electrical isolation between the contacts and prevents the short circuit of the current. When the connection needs to be disconnected, the plug and the socket are separated, and the conductive channel between the contacts is cut off, realizing high-voltage circuit breaking.

[0003] The existing Chinese patent with announcement number CN212462240U discloses a high-voltage connector and a high-voltage connector plug, including a shell, a cable, a shielding assembly and a locking assembly; the cable is inserted in the shell; the shielding assembly is installed between the shell and the cable; the shielding assembly includes a shielding sheet connected to the shell, and a shielding ring arranged around the outside of the cable; the shielding sheet is provided with a connecting hole, and the shielding ring is correspondingly inserted in the connecting hole; the shielding sheet is provided with a connecting sheet, the connecting sheet is arranged around the inner side wall of the connecting hole, and the connecting sheet abuts against the shielding ring.

[0004] Although the above scheme can improve the signal transmission quality of the high-voltage connector plug, when the high-voltage connector is in an unplugged state, fingers accidentally touching the live parts can easily cause electric shock, resulting in insufficient safety. At the same time, if the insertion of the positive and negative poles is difficult to distinguish when the light is poor, the positive and negative poles may be installed incorrectly, causing short circuits or other hazards. Therefore, it does not meet the existing needs. In this regard, we propose a high-voltage connector that is finger-touch-proof. Utility Model Content

[0005] The utility model aims to provide a finger-proof high-voltage connector to solve the problems in the above-mentioned background technology that the fingers of the high-voltage connector may accidentally touch the live parts and easily cause electric shock and the positive and negative electrodes may be installed incorrectly.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The utility model provides an anti-touch plate inside the docking hole. When a user accidentally inserts a finger into the docking hole, the anti-touch plate can prevent the finger from being inserted deep into the docking hole, thereby avoiding the problem of electric shock. When the docking head is docked with the docking hole, the anti-touch plate will be stuck in the groove and will not affect the normal docking use, thereby effectively improving safety.

When the plug and the socket are docked in dim light, the user can touch the rubber protrusion with a finger first. The rubber protrusion is conical. When the user touches it, the first spring will be pressed downward to avoid finger injury. The front and back sides of the docking can be known by touching the rubber protrusion. When both rubber protrusions are facing upward, docking can be carried out. Therefore, docking can be carried out in dim light, which increases practicality and is convenient and quick to use.

[0019] 3. The utility model provides fixing cylinders at the front and rear ends of the plug and the socket. After the plug and the socket are connected, the knob is turned, and the knob drives the threaded rod to be screwed into the threaded groove, thereby increasing the connection firmness between the plug and the socket and avoiding loosening after the connection. At the same time, a second spring is provided in the threaded groove. When the threaded rod is threadedly connected with the threaded groove, the friction between the threaded rod and the threaded groove can be increased by the second spring, so that the threaded rod and the threaded groove are connected more tightly, and the stability is further ensured.
