Description

Electrical Connector Assembly

【Technical field】

The utility model relates to an electrical connector assembly, in particular to an electrical connector assembly with a dust-proof cover.

【Background technique】

With the development of the portable computer, its application scope is increasing day by day, which requires that the portable computer can work normally in different environments. Generally speaking, the socket on the portable computer is usually in two states, one is docked with the external connector; The uncertainty of the working environment may cause some debris, especially dust, to intrude into it. When the dust adheres to the surface of the conductive terminal of the connector, it will cause poor contact, which will affect the docking effect and signal transmission with the external connector. quality. In order to ensure that the portable computer can work normally in different environments, someone once installed a dust cover at the socket of the portable computer. When the connectors are docked, use external tools to remove the dust cover. However, due to the difficulty in dismounting the dustproof cover of the electrical connector assembly, it is inconvenient for users to use, so there is still a need for further improvement.

【Content of utility model】

The purpose of the utility model is to provide an electrical connector assembly, which has a dust-proof cover that can prevent dust from intruding into the electrical connector, and the structure of the dust-proof cover is convenient for users to disassemble.

In order to achieve the above purpose, the utility model provides the following technical solutions: an electrical connector assembly, including an insulating body and a dust cover, wherein the insulating body is provided with a storage space that can accommodate a docking connector, and a front surface of the storage space is provided There is an opening for insertion of the butt connector, and a plurality of terminals protruding into the receiving space are assembled in the insulating body. The dust cover is assembled at the opening of the housing space of the insulating body, including a panel that covers the opening to prevent dust from intruding into the housing space, and is integrally formed with the panel, stored in the housing space and locked with the housing to fix the panel at the opening At the locking part, a spring is squeezed between the insulating body and the dust cover.

Compared with the prior art, the dustproof cover of the utility model can prevent dust and other sundries from entering the accommodation space of the connector, thereby keeping the terminals clean; the setting of the spring makes the dustproof cover easy to remove from the connector.

Below in conjunction with accompanying drawing and preferred embodiment the utility model is described further.

【Detailed ways】

Please refer to Fig. 1 to Fig. 4, the electrical connector assembly 1 of the present invention has a dustproof cover 40, which includes an insulating body 10, which is provided with a receiving space 11 for accommodating a mating plug connector (not shown), Its front surface is provided with an opening 12 that can be inserted into a mating plug connector, and a notch 13 is provided on its top surface near the front surface, and a pair of protrusions 14 are symmetrically arranged adjacent to the notch 13, and the rear side wall of the protrusion A blocking surface 14a is formed. The outer periphery of the insulating body 10 is also covered with a shielding shell 30 .

A plurality of terminals (not shown) are assembled in the insulating body 10, wherein each terminal includes a contact portion (not shown) extending into the accommodation space 11 of the insulating body 10, and a downwardly protruding insulating body 10. The tail portion (not shown) on the bottom surface can be inserted or soldered to a printed circuit board (not shown).

The opening 12 of the accommodation space 11 is assembled with a dustproof cover 40, which includes a panel 41 covering the opening 12 to prevent dust and foreign matter from falling on the contact portion of the terminal, a pair of panels extending from the rear side of the panel 41 and Symmetrically arranged side walls 43, a rear wall 44 connected to the rear ends of the two side walls 43 and close to the upper position, and a rear wall 44 located between the rear wall 44 and the panel 41 and one end is connected to the rear wall 44 and the other end is The elastic locking part 42 that extends in a free state obliquely upwards, wherein the dust cover 40 formed by the panel 41, the side wall 43, the rear wall 44 and the elastic locking part 42 is hollow in shape, and the rear wall 44 and the side wall The tail end of 43 forms a door-shaped receiving opening 45, and when the dustproof cover 40 is assembled into the receiving space 11, it can accommodate the contact portion of the terminal and prevent it from being damaged. In addition, the top surface of the elastic locking portion 42 near the free end is provided with a buckling portion 42d which can prevent the panel 41 from falling off, and a force application portion 42b connected with the buckling portion 42d. The force-applying portion 42b extends forward and passes through the notch 48 on the panel 41 to extend out of the panel 41 , so that the operator can directly press it.

5 and 6, when the dust cover 40 is assembled into the storage space 11, the front end of the force applying portion 42b is exposed outside the opening 12 for disassembly operation, and the panel 41 of the dust cover 40 is covered at the opening 12. , and the rest of them extend into the receiving space 11, wherein the contact part of the terminal is located below the receiving opening 45 of the dust cover 40, and the buckle part 42d of the elastic locking part 42 crosses the bump 14 of the insulating body 10 and contacts with the bump 14 The blocking surface 14a of the contact surface 14a abuts, and in this way the elastic locking part 42 is held in the receiving space 11 and will not fall off.

Please refer to Fig. 7 again, press down on the force applying part 42b, thereby driving the buckle part 42d to move down, and pull out according to the trend, the buckle part 42d crosses the blocking surface 14a of the protrusion 14 of the insulating body 10, in this way the The dust cover 40 is disassembled from the insulating body 10 .

The rear wall 44 of the dust cover 40 extends backward to form a protrusion 441 for nesting a spring 6 . After the dustproof cover 40 is assembled to the insulating body 10 , the spring 6 is pressed between the rear wall 102 of the insulating body 10 and the rear wall 44 of the dustproof cover 40 . When the locking portion 42d and the blocking surface 14a are unlocked, the spring 6 will drive the dustproof cover 40 to disengage from the insulating body 10, thereby avoiding the situation that the dustproof cover 40 is difficult to withdraw.
