Description

Connector

Technical Field

The application relates to the technical field of circuit connectors, in particular to a connector.

Background

The connector is mainly used for connecting data, signals and power between the network equipment and the mechanical equipment; it is a device that bridges two conductors on a loop, allowing current or signals to flow from one conductor to the other. Under the rapid development of global economy, the industry of medical equipment, aviation military industry, automobiles, communication, computers, consumer electronics, industry and the like of China is rapidly developed, and the market of the connector in China is kept in a high-speed growth state, so that the market scale of the connector in China is continuously enlarged.

When the existing line connector is in conductive connection with an electronic element of a cable joint, the electronic element is provided with a plurality of conductive holes, and each conductive hole is internally plated with a metal layer; the line connector comprises a connector body and a plurality of terminals arranged in the connector body; the terminals are respectively electrically connected with the electronic component and the circuit board, and each terminal is provided with a main body part and a contact part protruding from the main body, and the contact part is used for contacting with the metal layer. When the electronic component moves downwards to be matched with the circuit connector, the contact part enters the corresponding conductive hole of the electronic component to be contacted with the metal layer.

When connected, the cable joint needs to be inserted into the line connector in the front direction, however, when the insertion of the cable joint is unbalanced, the cable joint or the terminal of the line connector may be excessively inserted and damaged. In general, there is a need for a sufficient abutment force between each terminal and the corresponding metal layer to ensure stable contact, and for each terminal, if the abutment force is provided by the elastic force generated by the elastic deformation of the terminal when the metal layer is mated with the terminal, a larger stroke is required for the elastic deformation of the terminal. Therefore, the distance between the contact end of the contact portion and the main body portion is longer, and at the same time, the overall size of each terminal is also larger to accommodate the contact portion, so that the terminal has sufficient structural strength. Therefore, the overall size of the line connector is relatively large, which is disadvantageous in miniaturization.

However, in order to better plug in the cable connector, the terminals of the existing circuit connector are required to be contacted with the insulation part of the cable connector and receive a larger abutting force by the connector body, so that the terminals of the connector deeply scrape the insulator of the cable connector, and insulation fragments generated by the insulator adhere to the terminals of the connector, thereby affecting the stable contact between the terminals of the connector and the terminals of the cable connector, so that a need exists for a connector and a use method thereof.

In addition, the arc structure can improve vibration resistance, reduce poor contact caused by vibration, and in the production process, the shape, the size and the material of the contact terminal need to be precisely designed and manufactured, and the top of the conductive terminal B'6 can trend to the arc structure according to the shrinkage of self stress during forming, so that the processing precision is low, and the good electrical performance, mechanical performance and environmental performance of the contact terminal are ensured.

In one possible embodiment, at least one abutment tab 14 is provided on both the connector body and the partition 13, the abutment tab 14 having a tendency to extend into the insertion slot 11; at least one abutment groove 24 is provided around the cable joint 2, each abutment piece 14 being engageable in one of the abutment grooves 24 for clamping the cable joint 2.
