Description

Electrical connector

Technical Field

The present invention relates to a connector, and more particularly, to an electrical connector.

Background

Generally, a commonly used electrical connector interface is a Universal Serial Bus (USB), and is widely used by the public due to smaller size and portability, and is commonly installed and connected to connection holes and corresponding transmission lines of various portable electronic devices such as smart mobile communication devices and digital cameras.

Along with the trend of the electronic devices toward light, thin, small and compact designs, the electrical connector should have a reduced structural size as much as possible while meeting the relevant specifications. Therefore, no matter the electric connector is an insulation body, a metal shell or an assembly and combination structure between the insulation body and the metal shell, the structural strength of the electric connector is often reduced due to the reduction of the structure volume, and related structural conditions of the electric connector during plugging and unplugging actions, such as the strength and the times of the plugging and unplugging actions, are inevitably reduced, so that the local structure of the electric connector is easily deformed (bent).

Detailed Description

Fig. 1 is a schematic diagram of an electrical connector according to an embodiment of the utility model. Fig. 2 illustrates the electrical connector of fig. 1 from another perspective. Referring to fig. 1 and fig. 2, in the present embodiment, the electrical connector 100 includes an insulating body 110, a plurality of terminals 130, and a metal housing 120. The terminals 130 are respectively disposed on the insulating body 110, and the exposed portions of the terminals 130 from the insulating body 110 are used for being abutted with a plurality of terminals (not shown) of another electrical connector (not shown). The housing 110 is assembled to the metal shell 120, and thus forms the interface a1 for mating with another electrical connector. Here, the electrical connector 100 conforms to USB 3.0 or USB 3.1 specification, and has 9 terminals 130 disposed in the insulating body 110.

Fig. 3 and 4 are exploded views of the electrical connector from different perspectives. Please refer to fig. 3 and fig. 4 together, and compare fig. 1 or fig. 2. The present embodiment also provides rectangular coordinates X-Y-Z to facilitate the following description of the components. In the present embodiment, the metal shell 120 is further divided into a shell 121 and a tray 122, and the insulating body 110 has a base 112 and a tongue 111. Each terminal 130 extends from the base 112 to the tongue portion 111 and protrudes or is exposed from the tongue portion 111. The housing 121 is assembled to the base 112 and surrounds the tongue 111. The tray 122 extends from the housing 121 and carries the tongue 111 and wraps around a portion of the tongue 111.

Here, the electrical connector 100 is, for example, a socket electrical connector, which is inserted and fixed to a circuit board (not shown) through the plurality of wings 121d of the housing 121, and also welds (and electrically connects) the portion of the terminal 130 protruding from the base 112 to the circuit board.

Fig. 5 is a cross-sectional view of the electrical connector of fig. 1. Referring to fig. 3 to 5, in the present embodiment, the tray 122 includes a main plate 122b extending from the housing 121, two side plates 122c extending from the main plate 122b along two opposite sides of the X axis and bent, and two front stops 122a extending from the two side plates 122c and bent, respectively. More specifically, the tray 122 and the housing 121 are formed by stamping and bending the same metal plate, wherein the tray 122 extends from the rear edge of the housing 121 (toward the negative Y-axis direction and the positive Z-axis direction, and then toward the positive Y-axis direction) and enters the housing 121. Briefly, the tray 122 extends from the bottom 121a of the housing 121 away from the access opening A1 and then folds back into the housing 121. That is, the connection a2 between the main board 122b and the housing 121 and the front stop 122a are located on the other opposite sides of the main board 122b along the Y axis (the connection a2 is regarded as the rear edge of the housing 121, and the interface a1 and the front stop 122a can be regarded as the front edge), so that the main board 122b extends from the bottom 121a of the housing 121 away from the front stop 122a and then folds back into the housing 121, and the gap G1 is kept between the main board 122b and the bottom 121 a.

Based on the above, as shown in fig. 3 and fig. 4, when the insulating body 110 is assembled into the metal shell 120, the base 112 of the insulating body 110 is combined to the shell 121 of the metal shell 120, wherein the shell 121 has a recess 121b, the base 112 has a protrusion 112a, the protrusion 112a is embedded in the recess 121b, meanwhile, the shell 121 has a tab 121c, the base 112 has a recess 112b, and the tab 121c is snapped in the recess 112b, thereby completing the fixed connection between the insulating body 110 and the metal shell 120. More importantly, after the tongue 111 of the insulating body 110 extends into the housing 121, it is supported on the main plate 122b of the tray 122, the two side plates 122c provide the X-axis limit for the tongue 111, and form a U-shaped structure with the main plate 122b, and the pair of front stops 122a can prevent the tongue 111 from separating from the tray 122 in the positive Y-axis direction. It should be noted that the shell 121 of the present embodiment further has a back stop 123, which is formed by bending a part of the back edge of the metal shell 120 after the insulating body 110 is assembled into the metal shell 120, so as to abut against the base 112 of the insulating body 110. Thus, the front and rear stops 122a and 123 provide a complete limiting and fixing effect for the insulation body 110 along the Y-axis.

It should be noted that, as shown in fig. 3 and 5, the portion of the terminal 130 extending out or exposing the tongue portion 111 is located outside the range of the tray 122 covering the tongue portion 111. In other words, a portion of the terminals 130 will extend from the top surface of the tongue portion 111 (for example, the terminals 130 not cross-sectioned as shown in fig. 5), and another portion of the terminals 130 will be exposed from the top surface of the tongue portion 111 (for example, the terminals 130 cross-sectioned as shown in fig. 5), and the bottom surface of the tongue portion 111 will be abutted against the main board 122b of the tray 122, which corresponds to the top surface and the rear side (corresponding to the connection point a 2) of the tongue portion 111 not being covered by the tray 122, and at the same time, due to the existence of the gap G1, another electrical connector (for example, a plug electrical connector) can be inserted into the electrical connector 100 smoothly.

In summary, in the embodiments of the utility model, the electric connector covers and supports the tongue portion of the insulating body through the tray extending from the housing, so as to improve the structural strength, wherein for the housing, in the process of stamping and bending the same structural member (metal shell), the housing for surrounding the tongue portion and the tray for carrying and covering the tongue portion are formed at the same time. Therefore, in addition to the protection effect provided for the tongue part, the original processing technology is used to produce an additional finished tray, and the effect of saving the processing cost can be achieved. In other words, when the size of the electrical connector needs to be reduced, the length of the electrical connector can be reduced, and the problems of insufficient structural strength and the like caused by reduction can be overcome, so that the electrical connector has wider applicability.
