New Description: [New Technical Field] This creation relates to electrical connectors in the field of electronic devices, and more particularly to an electrical connector that prevents the male and female ends from being deformed by rotation of the insulating body within the metal casing. [First-hand technology] With the continuous development of electronic products, the connections between various electronic products and their peripheral devices are becoming more and more frequent, and electronic devices and their peripheral devices pass through various connectors (such as USB connectors, HDMI). Connectors, etc. to achieve the connection is a very common connection, so the frequency of use of various connectors also increases. It has been used so widely in the electronics field, so the production of connectors by the production partners has gradually changed from the original small-scale production to large-scale mass production. The variety of connectors is increasing, and people are more convenient to use. The existing electrical connector, especially the micro connector, comprises an insulative housing, a plurality of conductive terminals mounted on the insulative housing, and a metal housing covering the insulative housing and forming a plug cavity with the insulative housing. When in use, the plug having the metal housing is inserted. Connect to the plug cavity. However, due to cost limitation, the insulating body and the metal casing are fixed together by a clearance fit. When the plug is inserted into the plug cavity and contacts the insulating body, the insulating body is often driven to be selected in the metal casing, thereby causing the male and female ends to be inserted and deformed. Therefore, it is desirable to provide an electrical connector that overcomes the above drawbacks. [New content] The purpose of the present invention is to provide an electrical connector that prevents the insulating body from rotating in the metal casing and causing deformation of the male and female ends in response to the above-mentioned deficiencies of the prior art. The electrical connector provided by the present invention for the above purpose is used for plugging with a plug of a metal housing of the corresponding 3 M426911, which comprises an insulating body, a plurality of conductive terminals mounted on the insulating body, and a covered insulating body. The metal housing is formed with the insulating body, and the opposite sides of the rear end of the metal housing are provided with engaging recesses, and the insulating body is provided with an engaging boss that cooperates with the engaging recess. In summary, in the present invention, the opposite sides of the rear end of the metal casing are provided with engaging recesses, and the opposite sides of the rear end of the insulating body protrude outwardly to form an engaging boss which cooperates with the engaging recess, and is engaged by the engaging recess. The engagement of the slot and the snapping & platform effectively limits the rotation of the insulating body within the metal casing, avoiding the deformation problem when the male and female ends are inserted; on the other hand, the engaging groove and the engaging boss are used to solve the above technique. The problem is simple structure and low cost. [Embodiment] The technical contents, structural features, objects and effects achieved by the present invention will be described in detail below with reference to the embodiments. Referring to the first to third figures, the present electrical connector 100 is for interposing with a corresponding plug having a metal housing, and includes an insulative housing 20, a plurality of conductive terminals 30 mounted on the insulative housing 20, and a cover The insulative housing 20 and the insulative housing 20 form a metal housing 10 of the insertion cavity 11. The opposite sides of the rear end of the metal housing 10 are provided with engaging recesses 12, and the opposite sides of the rear end of the insulative housing 20 are provided with cards. The engaging boss 22 is engaged with the groove 12 to cooperate with each other. Referring to the first and third figures, in particular, the surface of the insulative housing 20 is provided with a plurality of terminal slots 21, and the conductive terminals 30 are received in the terminal slots 21. Preferably, referring to the first to third figures, the engaging recess 12 is a U-shaped recess and the opening is rearward, and the engaging boss 22 is a U-shaped boss that cooperates therewith. Specifically, the engaging recess 12 penetrates the wall of the metal casing 10. The mutual engagement of the U-shaped groove and the U-shaped boss further increases the connection stability between the insulating body 20 and the metal casing 10, further preventing the insulating body 20 from rotating within the metal casing 10. 4 M426911 Preferably, the engaging recesses 12 have at least two and are distributed at least on opposite sides of the metal peripheral 1 . Preferably, the front end of the metal casing 10 has an outwardly bent shape to form four guiding walls 13. The guiding wall jr stops the insertion of the plug into the plugging cavity, and guides the insertion of the plug. When the present assembly is assembled, the conductive terminal 3 is injection molded onto the insulative housing 2, and the back cover of the metal case 10 is opened, and the insulative housing 20 on which the conductive terminal 3 is mounted is inserted from the rear end of the insulative housing 10. And forming a plug cavity 11 between the metal case 1 and the engaging boss 22 of the insulative housing 2 into the engaging recess 12 of the metal case 10, and bending and closing the back cover of the metal case 1 The present electrical connector 100. In summary, the present invention is not only simple in structure, convenient in processing, and low in cost, but also effectively limits the rotation of the insulative housing 20 in the metal casing 1〇, thereby avoiding deformation problems when the male and female ends are inserted.
