Terminal structure of electrical connector

technical field

The utility model relates to the technical field of electrical connectors, in particular to the terminal structure of the electrical connector.

Background technique

Electrical connectors, with plug-and-pull functions, have been widely used in electronic products. The electrical connector generally includes an insulating body, terminals and a housing. The terminals are accommodated in the insulating body for electrical connection and signal transmission.

With the development of electrical connectors, the functional requirements for connectors are also higher, so that terminals with different performances are provided in an electrical connector, and terminals with different performances are used to enable the electrical connector to obtain multiple functions and achieve product quality. The miniaturization and multi-function characteristics. However, in actual production, terminals with the same performance are generally arranged on the same strip. To obtain terminals with different performances, at least two strips need to be formed separately. This form not only makes the production cumbersome, but also requires separate Open mold design, high cost, and when assembling, different material strips need to be assembled separately, which is quite inconvenient to assemble, especially when using injection molding, the two material strips are easily interfered, and the positioning is not good, resulting in low product quality. The defect rate is high.

Another object of the present invention is to provide a terminal structure of an electrical connector with a simple and compact structure, which is easy to form and saves material.

In order to achieve the above object, the utility model adopts the following technical solutions:

The terminal structure of the electrical connector includes a first signal terminal and a second signal terminal, wherein the first signal terminal and the second signal terminal are arranged at intervals in the length direction of the strip, and the contact portion of the second signal terminal is formed by The connecting arm extends beyond the contact portion of the first signal terminal.

The width of the connecting arm of the second signal terminal is smaller than the width of the contact portion, that is, the connecting arm is designed to converge relative to the contact portion, and the contact portion of the first signal terminal is formed on the side of the connecting arm.

The first signal terminal and the second signal terminal are mounted on the connector body in the same row, and the contact portion of the first signal terminal and the contact portion of the second signal terminal form two inner and outer sockets on the socket of the connector body Relationship; the main body of the connector is a USB3.0 electrical connector.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

Referring to Figures 1 and 2, the utility model relates to a terminal structure of an electrical connector, which includes a first signal terminal 1 and a second signal terminal 2, and the first signal terminal 1 and the second signal terminal 2 are arranged on the tape 3 are arranged at intervals along the length direction, and the contact portion 21 of the second signal terminal 2 extends beyond the contact portion 11 of the first signal terminal 1 from the connecting arm 22 .

As shown in Figures 1 and 2, the further structural design of the present invention is that the width of the connecting arm 22 of the second signal terminal 2 is smaller than the width of the contact part 21, that is, the connecting arm 22 is designed to converge relative to the contact part 21, and the first signal terminal The contact portion 11 of 1 is formed on the side of the connecting arm 22. The first signal terminal 1 and the second signal terminal 2 are formed at intervals in an orderly manner, and the length of the terminals is appropriately designed so that they form a front-to-back relationship. Then, by designing the connecting arm 22, two or two types of terminals can be simultaneously formed on the same strip 3. More than one terminal with different properties, the positional relationship between the terminals is stable, which is conducive to assembly on the main body of the connector, especially more convenient for the injection molding process, simplifies the processing and molding process of the electrical connector, and improves the assembly quality and product quality. quality.

In Figures 1 and 2, the contact portion 11 of the first signal terminal 1 is formed on the side of the connecting arm 22, and the contact portion 11 of the first signal terminal 1 has a shape that is slightly narrowed toward the end, and is designed as an elastic arch. As a result, a relatively sufficient space is obtained between the contact portion 11 and the connecting arm 22. When this structure is actually plugged and used, the contact portion 11 will not come into contact with the connecting arm 22 when it is pressed down by the plugging force. Ensure normal electrical transmission. The contact portion 21 of the second signal terminal 2 is designed to be straight and exceeds the contact portion 11 of the first signal terminal 1 , so that a larger contact surface can be obtained to meet the requirement of electrical plugging.

As shown in Figures 3 and 4, the first signal terminal 1 and the second signal terminal 2 are mounted on the connector main body 4 in the same row, and the contact portion 11 of the first signal terminal 1 and the contact portion 21 of the second signal terminal 2 are in the connector. On the plug interface of the main body, there are two internal and external plug-in connections. The connector body 4 is a USB3.0 electrical connector. The first signal terminal 1 and the second signal terminal 2 are molded on the strip 3 at the same time, so that the first signal terminal 1 and the second signal terminal 2 can be injection molded with the connector body 4 synchronously, and the positioning between the terminals is good , It is not easy to be deformed, dislocated, etc., it is easier to make, the product quality is higher, and the defective rate is effectively reduced. The contact part 11 of the first signal terminal 1 and the contact part 21 of the second signal terminal 2 provide two plug-in positions inside and outside, and the first signal terminal 1 and the second signal terminal 2 can be selected and used according to the insertion depth to obtain different transmission Performance, to achieve the miniaturization and multi-functional characteristics of the product.
