Detailed Description

Referring to fig. 1 to 4, a plug connector according to a first embodiment of the present invention includes an insulating housing 1, an elastic locking member 2 and a locking limiting member 3. The casing 1 is generally made of plastic and has a generally square shape, wherein two sides (in this embodiment, the front side and the rear side) of the casing 1 are respectively provided with an opening, a tongue plate 11 having at least one conductive pad 111 laid thereon is disposed inside the casing 1, the tongue plate 11 extends to the opening at the front side of the casing 1, and the conductive pad 111 is connected to a bus 12 entering from the opening at the rear side of the casing 1.

The housing 1 is formed by fixedly connecting a front housing part 13 and a rear housing part 14, wherein the front housing part 13 is formed with a slot 131 at the upper end of the rear side thereof and is provided with a plurality of fastening holes 132, and the rear housing part 14 is disposed at the slot 131 and is fixed with the front housing part 13 by inserting a plurality of wedge blocks 141 into the fastening holes 132. In other embodiments, the housing 1 may be integrally formed (including injection-molded and integrated).

The front housing 13 has a mounting groove 133 at the center of the top surface for the locking element 2 to be fixed and received therein. In the present embodiment, the locking element 2 is formed by bending a long sheet-like object made of metal or plastic material, and a bottom portion 22 and a pressing portion 23 are respectively disposed on two sides of the bending section 21, and the included angle between the two is smaller than 90 degrees. A plurality of wedge blocks 134 are disposed in the mounting groove 133, when the locking member 2 is assembled, as shown in fig. 4, the bottom 22 is abutted against the mounting groove 133 and pushed in from the rear side of the housing 1, and then the bottom 22 passes through the wedge blocks 134 to generate a reverse blocking effect, so that the locking member 2 is fixed in the mounting groove 133, and the pressing portion 23 is suspended above the top surface of the housing 1. The pressing portion 23 has a pressing end 24 formed at the end thereof for being pressed by a user, the pressing end 24 is located above the rear housing portion 14, and the pressing portion 23 will rebound after the pressing end 24 is pressed to move the pressing portion 23 toward the base portion 22 based on the material and shape of the locking element 2.

In this embodiment, the pressing portion 23 includes a first slope section 231 and a second slope section 232, wherein the first slope section 231 is connected to the bending section 21, the second slope section 232 is connected between the first slope section 231 and the pressing end 24, and the slope of the first slope section 231 is smaller than the slope of the second slope section 232. The first slope section 231 is provided with a plurality of fastening blocks 25, and the fastening blocks 25 are used for fastening to a socket connector (not shown) opposite to the plug connector. When the plug connector is inserted into the socket connector, the buckling blocks 25 are automatically clamped into the buckling holes of the socket connector, so that the plug connector is locked on the socket connector. When the user presses the pressing end 24, the button block 25 will leave the button hole along with the movement of the pressing portion 23, thereby realizing unlocking.

In addition, the body of the latch limiting member 3 is formed into an elongated rod shape, and two ends of the elongated rod respectively extend downward to be connected to the top surface of the front shell 13 and abut against the rear shell 14 to form a U shape; in the present embodiment, the latch stop 3 is integrally formed with the front housing 13. The lock latch limiting member 3 spans over the lock latch 2 and is located between the pressing end 24 and the fastening block 25; in the present embodiment, the latch limiting member 3 spans over the first slope segment 231 and is adjacent to and above the connection between the first slope segment 231 and the second slope segment 232. In addition, a concave portion 31 is further disposed on a side of the latch limiting member 3 facing the pressing end 24, and a width of the concave portion 31 in the left-right direction is slightly larger than a width of the second slope section 232, so that the second slope section 232 can pass through the concave portion 31 and can bypass the latch limiting member 3. The left and right sides of the first slope section 231 are respectively provided with a limiting arm 26 extending outwards from the first slope section 231. The inner sides of the two ends of the lock latch limiting member 3 are correspondingly provided with pressing grooves 32. The height of the abutting grooves 32 is lower than the body of the latch limiting member 3, so that when the latch member 2 is fixed in the mounting groove 133, the two limiting arms 26 abut against the two abutting grooves 32, respectively, and a gap is formed between the latch member 2 and the body of the latch limiting member 3.

With the above structure, the pressing portion 23 of the locking element 2 extends from the bending portion 21 to the outside of the locking-element stopper 3 (i.e. the bending portion 21 and the pressing end 24 are located at two opposite sides of the locking-element stopper 3), so that some foreign objects and external forces can be prevented from directly touching the pressing portion 23, and the probability of accidental unlocking caused by accidental touching of the pressing portion 23, even the deformation or damage of the locking element 2, can be reduced. The latch stop 3 can extend outside the pressing portion 23 to provide a protection effect, but the pressing end 24 can still be designed to be higher than the latch stop 3, so as not to hinder the normal use of the user for pressing and unlocking.

The utility model discloses still provide the second embodiment as shown in fig. 5, fig. 6. The structure of the present embodiment is based on the structure of the first embodiment, and a pull tape 4 is added to generate the effect of assisting in pressing the pressing end 24. Specifically, one end of the drawstring 4 is connected to the latch limiting member 3, and may be wound, bound, folded, attached or fixed in other ways, and the drawstring 4 extends above the pressing end 24; on the other hand, a drawstring guide 5 extends out from the rear side of the rear shell 14 along the horizontal direction, and a through hole 51 extending along the height direction is formed on the drawstring guide 5; the through hole 51 is preferably formed to extend obliquely forward from the top to the bottom. The drawstring 4, after extending past the pressing end 24, passes down through the perforation 51 and abuts against the bottom edge of the drawstring guide 5. Since the pressing end 24 is higher than the latch-limiting member 3 and the pull-strip guiding portion 5, as shown in fig. 7, the pull strip 4 first assumes an upward inclined shape after starting from the latch-limiting member 3, and then assumes a downward inclined shape after passing over the pressing end 24 and passes through the through hole 51, and the end 41 of the pull strip 4 is lower than the pressing end 24. In other words, the latch limiting member 3 is a pull strip fixing end, the pull strip fixing end and the pull strip guiding portion 5 are respectively located at two opposite sides of the pressing end 24 and are arranged in a straight line with the pressing end 24 in the front-rear direction, the pull strip fixing end and the pull strip guiding portion 5 are both lower than the pressing end 24 in the height direction, and one end of the pull strip 4 is connected to the pull strip fixing end and passes through the pull strip guiding portion 5.

Through the above structure, in the embodiment, as shown in fig. 8 in actual use, when the tail end 41 of the pull belt 4 is pulled backwards, based on the height difference factor between the pressing end 24 and the pull belt guiding portion 5, no matter whether the pulling direction is horizontal, the pull belt 4 will generate downward pressure to the pressing end 24, so that the pressing end 24 moves downward, and further the unlocking is realized, thereby providing the convenient operation experience for the user.
