Electrical connector

This creation relates to the field of electrical connectors, and more particularly to an electrical connector mounted on a circuit board.

In today's electronic products, electrical connectors are an extremely important electronic component that directly affects the stability of the product's performance and ease of use. Electrical connectors, as the name implies, are used to achieve electrical connections. The purpose is to enable the transmission of electrical signals from one electronic component to another. Therefore, electrical connectors are widely used in various electronic products, such as computers. Mobile phones, digital cameras, televisions, etc., the types of electrical connectors are also very diverse depending on the application requirements, the most common are: USB connector, HDMI connector, RJ45 connector.

In the prior art, most of the electrical connectors usually include an insulative housing and a conductive terminal held in the insulating body. Of course, in order to improve the transmission quality of the electrical signal, in many electrical connectors for high-frequency signal transmission, A metal casing coated on the insulative housing is used to achieve a mask signal and anti-interference. At present, in order to maintain a stable connection with the insulating body, most metal housings are often provided with openings on the top or bottom surface of the metal housing, and bumps are provided at corresponding positions of the insulating body, through the openings and the bumps. The buckle realizes the holding connection. However, since the hole is to be opened in multiple places on the metal casing, the effect of the casing mask signal is affected to some extent, and the opening requires an additional punching procedure, and in addition, due to the volume of the insulating body itself. Smaller, so the size of the bumps will also be limited, and the strength of the small-sized bumps is often less than ideal. During the process of snapping with the metal casing, it is easily worn, resulting in a gap between the insulating body and the metal casing. The snap fit is not stable enough.

Therefore, it is indeed necessary to provide a new electrical connector to solve the above technical problems.

The purpose of the present invention is to provide an electrical connector that maintains a good fixed relationship between the two by improving the structure of the insulating body and the shielding case, and the assembly process is also very convenient.

In order to solve the above technical problem, the present invention adopts the following technical means: an electrical connector, comprising an insulating body, a shielding shell fixed on the insulating body, and a plurality of conductive terminals housed in the insulating body, the shielding shell The body is mounted on the insulative housing, and is provided with a main body portion covering the periphery of the abutting portion and a fixing portion extending rearward from the main body portion; the fixing portion includes a pair of positioning plates extending from upper and lower sides of the main body portion, and A pair of fixed arms extending from the left and right sides of the main body.

In the above electrical connector, the insulative housing is provided with a base portion and an abutting portion extending from the base portion, the base portion is provided with a pair of shoulder portions and a beam connecting the shoulder portions; the beam is provided with a top surface and a front end surface, the top surface is provided There is a groove; the positioning plate is in the form of a sheet and cooperates with the beam.

In the above electrical connector, the positioning plate is provided with a protrusion that cooperates with the groove, and the protrusion is recessed downward from the top surface of the positioning plate and protrudes toward the groove.

In the above electrical connector, the positioning plate is provided with an inclined section and a horizontal section, and the protrusion is formed on the horizontal section, and the inclined section is connected to the main body.

In the above electrical connector, the fixing arm extends horizontally and is provided with a hook tail.

In the above electrical connector, a slot for receiving the fixed arm is disposed between the shoulder and the abutting portion.

In the above electrical connector, the top surface of the beam is lower than the top surface of the shoulder.

Compared with the prior art, the present invention has improved the structure of the shielding shell and the insulating body, so that the two have a good snap-fit relationship, which can provide a stable and reliable connection, and has a simple structure and is easy to manufacture and assemble. .

As shown in the first and second embodiments, the present invention provides an electrical connector 100 including an insulative housing 10, a shielding housing 20 fixed to the insulative housing 10, and a plurality of housings received in the insulative housing 10. Conductive terminal 30. The electrical connector 100 is used for docking connection with a pair of electrical connectors (not shown) to enable transmission of electrical signals.

The insulative housing 10 is provided with a base portion 11 and an abutting portion 12 extending from the base portion. The base portion 11 is provided with a pair of shoulder portions 110 and a beam 111 connecting the shoulders. The shoulder portion 110 protrudes rearward relative to the beam 111 such that a gap 112 is formed between the shoulder portion 110 and the beam member 111. The beam 111 is provided with a top surface 113 and a front end surface 114. The top surface 113 is provided with a recessed groove 115, and the top surface 113 of the beam is slightly lower than the top surface 116 of the shoulder 110. A slot 117 is defined between the shoulder 110 and the abutting portion 12. The abutting portion 12 is provided with a rectangular pair of frame openings 120 and guiding portions 121 on both sides of the mating frame opening 120 for the smooth insertion of the mating electrical connector for electrical docking.

The shielding case 20 is mounted on the insulative housing 10, and is provided with a main body portion 21 that covers the periphery of the abutting portion 12 and a fixing portion that extends rearward from the main body portion 21. The fixing portion includes a pair of positioning plates 22 extending from upper and lower sides of the main body portion 21, and a pair of fixing arms 23 extending from left and right sides of the main body portion 21. The fixing arms 23 extend horizontally and are provided with a hook tail portion. 24, for inserting into the insulating body slot 117 and hooking the rear side of the insulative housing 10, thereby achieving mutual positioning in the docking direction (ie, the front-rear direction). The positioning plate 22 is in the form of a sheet, and is provided with a protrusion 220 that cooperates with the groove 115. The protrusion 220 is recessed from the top surface of the positioning plate 22 and protrudes toward the groove 115. In addition, the positioning plate 22 is provided. There is a sloped section 221 and a horizontal section 222 formed on the horizontal section 222, which is connected to the main body portion 21.

The shielding shell 20 is fixedly positioned with the insulating body 10 through the fixing arm 23 and the positioning plate 22. Since the top surface 113 of the beam is slightly lower than the top surface 116 of the shoulder 110, the positioning plate 22 can be made. 22 is located between the shoulders 110 and mates with the beam 111 to achieve a fixed positioning.

Each of the conductive terminals 30 is assembled into the insulative housing 20 from the rear to the front and is received in the mating portion 12 for electrical docking with a mating electrical connector (not shown).

In summary, the electrical connector 100 of the present embodiment is improved through the structure of the insulative housing 10 and the shielding housing 20, so that the fixed relationship between the two is more stable, can meet the requirements of frequent plugging and unplugging, and has a simple structure. The manufacturing and assembly process is convenient.

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention in any way. Any person skilled in the art can use the method disclosed above without departing from the scope of the patent application. Many possible changes and modifications to the technical means of this creation are within the scope of the scope of the patent application.
