Description

Technical Field

[0001] The utility model relates to the technical field of double-shell automobile connectors, in particular to a double-shell automobile connector. Background Art

[0002] The automotive connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can achieve the predetermined function. The form and structure of the automotive connector are ever-changing. It is mainly composed of four basic structural components, namely: contact, shell (depending on the type), insulator, and accessories. In the industry, it is usually called sheath, connector, and plastic shell. There are many types of automotive connectors now, which is convenient for the staff to use, but most of the existing automotive connectors are single-row settings. In some cases, the setting of single-row automotive connectors is limited. When the single-row automotive connector is damaged, it is necessary to replace and reconnect the automotive connector, which is time-consuming and laborious, or when two automotive components need to communicate and connect, they cannot be quickly connected and can only be connected one by one.

[0003] The existing Chinese patent CN217823329U discloses a double-row sunken plate type automobile connector. The double-row sunken plate type automobile connector has the advantages of double insurance, high connection safety, and high connection efficiency. It prevents the situation where a worker has to re-operate the connection due to damage to a certain contact part. It has a higher fault tolerance rate and solves the problem that most existing automobile connectors are single-row settings. When a single-row automobile connector is damaged, it needs to be replaced and reconnected, and multiple automobile parts cannot be quickly connected and can only be connected one by one.

[0004] The above-mentioned double-row sunken plate type automotive connector has a high connection efficiency through a double-row setting, which can prevent the situation where a worker has to re-operate the connection due to damage to a contact part, and has a high fault tolerance rate. However, in actual use, there is a need to regularly disassemble and maintain the connector to avoid long-term use, which poses certain safety hazards. Utility Model Content
