technical field

The utility model relates to an electric connector, in particular to an electronic card connector.

Background technique

In order to store more data, electronic products such as mobile phones and MP3 players often need to insert an electronic card, so these electronic products need to be provided with an electronic card connector for connecting the electronic card and conducting signals. Chinese Patent Publication No. 1874076 discloses an electronic card connector, which includes a body, a plurality of signal terminals accommodated in the body, and a housing. The casing has a top wall, the casing is fastened on the body, and the top wall of the casing and the body enclose an accommodating space, and the accommodating space is used for accommodating an electronic card.

However, the current trend toward miniaturization and multi-function of electronic products requires that the space occupied by the electronic card connector be as small as possible. The above-mentioned electronic card connector utilizes the top wall and the main body of the casing to cover and fix the electronic card, so that the electronic card connector occupies a large space, which is not suitable for the development requirements of current electronic products.

Utility model content

The purpose of the utility model is to provide an electronic card connector which occupies less space in view of the defects and deficiencies of the prior art.

In order to achieve the above object, the electronic card connector provided by the utility model includes a body, a plurality of signal terminals, at least a first shell and a second shell, the body has a base plate and is connected to the opposite side edges of the base plate The first side wall and the second side wall; the signal terminal is fixed on the substrate; the first housing is fixed on the first side wall; the second housing is fixed on the second side wall; A clamping cavity and a clamping cavity are respectively formed on both sides of the base plate.

As mentioned above, when the electronic card connector of the utility model is inserted, the two side edges of the electronic card can be clamped and fixed by the cavity wall of the clamping cavity and the cavity wall of the clamping cavity, so that it is not necessary to use the top wall of the housing The electronic card can be fixed by covering, so the overall height of the electronic card connector can be reduced, so that it occupies less space and meets the needs of the development of electronic products.
