In other embodiments, the male connector 10 may also be a USB (Universal Serial Bus) male.

Referring to fig. 2, the male connector 10 includes a plug end 11 and a housing 13, one end of the plug end 11 has a plug port 11a, and the plug end 11 can be inserted into the HDMI female socket through the plug port 11a. With reference to fig. 1 and 2, the plugging end 11 has a plugging direction, a thickness direction and a width direction, which are perpendicular to each other two by two, wherein the plugging direction can be simply understood as the plugging direction of the male connector 10 during use. For simplifying the expression, a rectangular coordinate system can be established with the inserting direction as an X axis, the width direction as a Y axis and the thickness direction as a Z axis.

Referring to fig. 2 and 3, the mating terminal 11 may include a housing 111 and conductive terminals 113, the conductive terminals 113 are disposed in the housing 111, and the conductive terminals 113 are arranged in a width direction (Y direction) of the mating terminal 11. The housing 111 has a socket 11a, a connecting section 11b opposite to the socket 11a, and a torsion-preventing protrusion 11c provided on the connecting section 11 b. In the embodiment where the male connector 10 is an HDMI male connector, the outer contour of the cross section of the socket 11a is substantially trapezoidal, and two end surfaces in the thickness direction (Z direction) are flat, so as to facilitate the male connector 10 to be inserted into an external interface. In the thickness direction of the inserting end 11, the connecting sections 11b at two opposite sides of the inserting end 11 respectively protrude from the flat end surface of the housing 111, that is, compared with the housing 111 at the flat end surface, the thickness of the connecting sections 11b is greater than that of the housing 111 at the flat end surface. The connecting section 11b is used for penetrating through the housing 13 of the male connector 10, so that the housing 13 is fixedly connected with the plugging end 11, and the anti-torsion protrusion 11c is accommodated in the housing 13 and abuts against the housing 13. The anti-rotation protrusion 11c protrudes from the connecting section 11b in the thickness direction, that is, the end of the anti-rotation protrusion 11c protrudes from the end of the connecting section 11b in the thickness direction of the insertion end 11.

Further, in the embodiment of the present invention, in the thickness direction, the opposite sides of the connecting section 11b are both provided with the anti-torsion protrusions 11c. In other words, in the thickness direction of the plugging end 11, both sides of the connecting section 11b can be abutted to the housing 13 through the anti-torsion protrusion 11c, so that the stress of the plugging end 11 is more balanced, and the connection stability of the plugging end 11 on the housing 13 is improved.

Further, referring to fig. 3, the housing 111 includes an insulating base 1111 and a shielding cover 1113 sleeved on the insulating base 1111, the insulating base 1111 is generally made of an insulating material such as plastic or rubber, and a plurality of slots 111a are formed therein and spaced apart along a width direction, and the plurality of conductive terminals 113 are embedded in the slots 111a in a one-to-one correspondence manner to ensure mutual insulation between the conductive terminals 113. The insulator 1111 has a connection section 11b, and the shield 1113 has a torsion preventing protrusion 11c. The shielding cover 1113 is made of metal and is used to prevent the external electromagnetic signal from interfering the data transmission of the conductive terminal 113. The shielding cover 1113 is sleeved outside the insulating base 1111 and can be connected with the insulating base 1111 in a hot melting mode or in an interference fit mode, so that the connection reliability of the shielding cover 1113 and the insulating base 1111 is guaranteed.

With continued reference to fig. 2, the connecting section 11b is provided with a clearance groove 11b1, one end of the shielding cover 1113 extends into the clearance groove 11b1, and at least a portion of the anti-torsion protrusion 11c is accommodated in the clearance groove 11b 1.

In other embodiments, more than two anti-rotation protrusions 11c may be provided, and the anti-rotation protrusions 11c may be fixed to the shield 1113 by welding or other connection methods. Correspondingly, more than two card holes 11d can be arranged at intervals in the width direction of the inserting end 11.

The fastening hole 11d can also be used for assembling and positioning the shield 1113 on the insulating base 1111. For example, the clearance groove 11b1 is provided therein with a latch 11e inserted into the latch hole 11d to latch the shield 1113 with the insulating base 1111, and the latches 11e correspond to the latch holes 11d one by one. The engaging block 11e can limit the shield 1113 in the inserting direction (X direction) to ensure the connection reliability between the shield 1113 and the insulating seat 1111, and prevent the male connector 10 from being separated from the insulating seat 1111 during inserting and pulling.

The stopper 11f may be formed by a press bending process. After the shielding cover 1113 and the insulating base 1111 are assembled and fixed, in the inserting direction, the stopping portion 11f abuts against the connecting section 11b to limit the displacement of the shielding cover 1113 in one direction of the inserting direction, and the matching of the locking block 11e and the locking hole 11d can limit the displacement of the shielding cover 1113 in the other direction of the inserting direction, so that the connection stability of the shielding cover 1113 and the insulating base 1111 can be ensured.

Referring to fig. 2 and 3, the shield 1113 has a limiting rib 11g spaced apart from the anti-rotation protrusion 11c, the limiting rib 11g being closer to the insertion opening 11a than the anti-rotation protrusion 11c, the limiting rib 11g being used to limit the range of movement of the housing 13 relative to the shield 1113 in the insertion direction. Spacing protruding muscle 11g extends along the circumference of grafting end 11, and spacing protruding muscle 11g can adopt stamping forming's mode shaping in shield cover 1113, and after shield cover 1113 and insulator housing 1111 equipment shaping, one side that deviates from insulator housing 1111 in shield cover 1113's the level and smooth terminal surface of spacing protruding muscle 11g protrusion. In some embodiments, the stop rib 11g may extend continuously and be closed in the circumferential direction in the peripheral direction of the insertion end 11. In other embodiments, the limiting ribs 11g are spaced apart from each other in the circumferential direction of the insertion end 11, i.e. the insertion end 11 does not have to extend continuously. Further, the stopper rib 11g is closer to the socket 11a than the stopper portion 11 f. In some embodiments, the retention bead 11g is located approximately 2/3 of the mating end 11.
