New description: [New technical field] The present invention relates to a connector, and more particularly to an electrical connector having a dustproof function. [Prior Art] Press, today's electrical connectors are usually required to have a dustproof function. The dustproof function of the electrical connector is usually achieved by covering a plastic cover with a plastic dust cover. However, with the development of electronic product technology, electrical connectors are required to be thinner and thinner, and correspondingly, the size of the dust cover is also designed to be smaller. Since the dust cover of the above conventional electrical connector is made of a single plastic material, the strength is small, and it is easy to be deformed during use, resulting in loss of dustproof function. [New Content] The purpose of this creation is to provide an electrical connector that can improve strength and is less prone to deformation in view of the above-mentioned drawbacks of the prior art. In order to achieve the above object, the electrical connector of the present invention comprises: an insulative housing, a plurality of terminal card slots are defined in the insulative housing, and a conductive terminal is inserted into the terminal card slot; and the insulative housing is further provided with a metal housing. The metal cover is provided with a dust cover, and the dust cover has a plastic body, and a metal reinforcement body is fastened and fixed on the plastic body. As described above, since the dustproof cover of the present invention has a metal reinforcing body fixed to the plastic body, the overall strength of the dustproof cover can be improved, so that the dustproof cover can be ensured even if the size of the dustproof cover is designed to be small. In 5 M344626, it can be used in a sufficient strength to make it difficult to prevent dust. ^ [Embodiment] In order to explain the technical content, structural features, and functions of the present invention in detail, the following examples are given in conjunction with the drawings, including a description of the first and second figures. Connector ^ Ming. The edge body 1〇, the insulating body 1G is provided with a plurality of guides;
