Description

Connector

Technical Field

The utility model relates to the technical field of connectors, in particular to a connector.

Background

A connector is a device that connects two active devices and is used to transmit current or signals. The main mating fields of the electric connector include traffic, communication, network, IT, medical treatment, household appliances and the like, and the rapid development of the product technology level and the rapid growth of the market thereof in the mating fields strongly pull the development of the connector technology. Up to now, connectors have been developed into a series and specialization of products with complete product types, rich variety specifications, various structural types, subdivision in specialized directions, obvious industrial features, and standard system specifications. The structural design of the existing connector is unreasonable, and the connector does not have a fool-proof function, so that the connector and the circuit board are reversely inserted. The connector has the defects of unreliable performance, unreliable connection and inconvenient assembly.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the connector which has the advantages of simple structure, stable and reliable performance and reliable connection.

In order to achieve the above purpose, the connector comprises a rubber core and a plurality of pins arranged on the rubber core, wherein one end of each pin is provided with a first inserting part extending outside the rubber core and being inserted with a circuit board, the other end of each pin is provided with a second inserting part extending in the rubber core, the first inserting parts of the pins are arranged in a linear interval mode, the first inserting parts of the two pins are respectively provided with arc-shaped protruding limiting parts, the rubber core is provided with fool-proof limiting columns corresponding to the first inserting parts, and the rubber core is provided with heat dissipation grooves corresponding to the first inserting parts of the pins.

The beneficial effects of the structure are as follows: be provided with protruding spacing portion of arc on the contact pin to can guarantee that the contact pin is compacter with the connection of circuit board, connect more reliably, and prevent slow-witted spacing post can play and prevent slow-witted effect, can avoid this connector to insert with the circuit board and turn over, and be provided with the radiating groove on the rubber core, can avoid the rubber core laminating on the circuit board, be favorable to the heat dissipation of circuit board, thereby this connector has simple structure, stable performance is reliable, connect reliable advantage.

Particularly, the contact pin is respectively provided with a large limiting block and a small limiting block which are clamped in the rubber core, a limiting groove is formed between the large limiting block and the small limiting block, and the limiting groove is clamped in the rubber core and forms limiting fit of the contact pin and the rubber core. The contact pin is in limit fit with the rubber core, so that the contact pin is not easy to loosen and fall off, and the large limit block and the small limit block can be embedded in the rubber core, so that the contact pin and the rubber core can be more compactly connected.

Particularly, a guide groove is arranged in the rubber core corresponding to the second plug-in connection part. The guide groove can play a guiding role, and the connector can be inserted more smoothly during insertion.

Detailed Description

As shown in fig. 1 to 3, the embodiment of the utility model is a connector, which comprises a rubber core 10 and a plurality of pins 11 arranged on the rubber core 10, wherein one end of each pin 11 is provided with a first inserting part 111 extending outside the rubber core 10 and being inserted with a circuit board, the other end of each pin 11 is provided with a second inserting part 112 extending inside the rubber core 10, the first inserting parts 111 of the pins 11 are arranged in a line shape at intervals, the first inserting parts 111 of the two pins 11 are respectively provided with an arc-shaped protruding limiting part 113, the position of the rubber core 10 corresponding to the first inserting part 111 is provided with a foolproof limiting post 12, and the position of the rubber core 10 corresponding to the first inserting part 111 of the pins 11 is provided with a heat dissipation groove 101.

As shown in fig. 2 and 3, the pin 11 is respectively provided with a large limiting block 114 and a small limiting block 115 which are clamped in the rubber core 10, a limiting groove 116 is formed between the large limiting block 114 and the small limiting block 115, and the limiting groove 116 is clamped in the rubber core 10 and forms limiting fit between the pin 11 and the rubber core 10. The contact pin is in limit fit with the rubber core, so that the contact pin is not easy to loosen and fall off, and the large limit block and the small limit block can be embedded in the rubber core, so that the contact pin and the rubber core can be more compactly connected. The rubber core 10 is provided with a guide groove 102 corresponding to the second insertion part 112. The guide groove can play a guiding role, and the connector can be inserted more smoothly during insertion.

Be provided with protruding spacing portion of arc on the contact pin to can guarantee that the contact pin is compacter with the connection of circuit board, connect more reliably, and prevent slow-witted spacing post can play and prevent slow-witted effect, can avoid this connector to insert with the circuit board and turn over, and be provided with the radiating groove on the rubber core, can avoid the rubber core laminating on the circuit board, be favorable to the heat dissipation of circuit board, thereby this connector has simple structure, stable performance is reliable, connect reliable advantage.
