In the above structure, an integrally formed wire sleeve is arranged below the molding member, and a through hole for passing the data wire is reserved on the wire sleeve.

In the above structure, the upper plane of the socket set is flush with the top end surface of the protective casing.

In foretell structure, all be provided with two spacing strips that parallel on the relative two inside walls of protecting sheathing, form spacing draw-in groove between two spacing strips, the both sides that the PCBA board is relative all block in the spacing draw-in groove.

In the structure, the outer surface of the socket sleeve is provided with a buckle protruding outwards, and the inner wall of the protective shell is correspondingly provided with a clamping groove.

The utility model has the advantages that: a distance is reserved between the two sides of the PCBA and the inner wall of the protective shell, and enough space is reserved for the PCBA, so that the PCBA is prevented from being damaged in the outer mold injection molding process, and even if glue overflows, chips on the PCBA are prevented from being damaged; meanwhile, due to the reserved cavity, heat on the PCBA board can be dissipated into the cavity, and the heat dissipation effect of the PCBA board is improved.

Detailed Description

The present invention will be further explained with reference to the drawings and examples.

The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection/connection relations referred to in the patent do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection auxiliary components according to specific implementation conditions. The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.

Referring to fig. 1 and 2, the present invention discloses a dual card reader, which can read an SD card and a TF card, and specifically, the dual card reader includes a protection housing 10, a data line 20, a fixing base 30, a PCBA board 40 and a socket kit 50; protective housing 10 be both ends open-ended tubular structure, in this embodiment, protective housing 10 is the cuboid form, and the structure of arc transition is adopted to its corner, avoids the corner too sharp, reduces to use and experiences. As shown in fig. 1, the socket set 50 is fixed at the upper opening of the protective casing 10, an SD card socket 501 and a TF card socket 502 are provided on the socket set 50, and the upper plane of the socket set 50 is flush with the top end surface of the protective casing 10.
