The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1 and 2, the plug-in type connection device according to one embodiment of the present invention includes a plug 100 and a socket 200, the socket 200 has a socket 210 and a socket 220, the plug 100 is inserted into or pulled out of the socket 210 through the socket 220, the plug 100 has an elastic engaging portion 300, the elastic engaging portion 300 is used for locking the plug 100 in the socket 210, the elastic engaging portion 300 has an operating end 310 extending toward the socket 220, and the operating end 310 can drive the elastic engaging portion 300 to deform to release the plug 100.

In order to lock the elastic engaging portion 300 in the socket 210, the socket 200 of the present embodiment is provided with a fixed engaging portion matching the elastic engaging portion 300, which is exemplified by: the elastic engaging portion 300 is provided with a first engaging protrusion 330, the fixed engaging portion is a second engaging protrusion 230 provided on the socket 200, and the second engaging protrusion 230 locks the plug 100 by stopping the first engaging protrusion 330. The first catching protrusion 330 has a first guide slope 332 and a first stop surface 331, and the second catching protrusion 230 has a second guide slope 231 and a second stop surface 232.

In this embodiment, a gap for providing a deformation space for the elastic engaging portion 300 is provided between the socket 200 and the elastic engaging portion 300, for example, as shown in fig. 2, a gap is formed between a side wall of the socket 200 opposite to the second engaging protrusion 230 and the elastic engaging portion 300, so as to provide a sufficient deformation space for the elastic engaging portion 300 during the assembling and disassembling processes of the plug 100, and ensure that the plug 100 and the socket 200 can be assembled and disassembled smoothly.

According to the plug-in type connecting device of this embodiment, when assembling, the plug 100 is inserted into the socket 210 through the socket 220, when the first guiding inclined plane 332 of the first engaging protrusion 330 interferes with the second guiding inclined plane 231 of the second engaging protrusion 230, the first engaging protrusion 330 is pressed by the second engaging protrusion 230 to drive the elastic engaging portion 300 to deform in a direction away from the second engaging protrusion 230, until the elastic engaging portion 300 rebounds after the first engaging protrusion 330 passes the second engaging protrusion 230, and the first stopping surface 331 of the first engaging protrusion 330 is stopped by the second stopping surface 232 of the second engaging protrusion 230 in the direction of pulling out the plug 100 to lock the plug 100, thereby completing the assembling connection between the plug 100 and the socket 200. In the assembling process, when the elastic clamping part 300 locks the plug connector 100, in-place hand feeling or in-place sound is generated, an operator can judge that the plug connector 100 is connected in place, the assembling power is improved, the locking of the elastic clamping part 300 prevents the plug connector 100 from falling out of the socket slot 210, and the connecting reliability of the plug connector 100 and the socket connector 200 is improved.

According to the plug-in type connection device of the embodiment, when detaching, since the elastic engaging portion 300 has the operation end 310 extending to the plug interface 220, that is, the operation end 310 is directly exposed to the plug interface 220, an operator can apply force to the operation end 310 in a direction away from the second engaging protrusion 230, the operation end 310 drives the elastic engaging portion 300 to deform until the stop of the second stop surface 232 on the first stop surface 331 is removed, so as to unlock the plug connector 100, the plug connector 100 can be pulled out from the plug interface 220 of the socket member 200, and the detaching operation is more convenient.

Compared with the prior art, the plug-in type connecting device of the embodiment can ensure the connection reliability of the plug-in element 100 and the socket element 200, and can realize the quick assembly and disassembly of the plug-in element 100 and the socket element 200.

As a simple variation of this embodiment, a second engaging hole may be disposed on the elastic engaging portion, the fixed engaging portion is a second engaging protrusion disposed on the socket, and the second engaging protrusion is inserted into the second engaging hole to lock the plug; alternatively, as shown in fig. 3, the elastic engaging portion 300 is provided with a first engaging protrusion 330, the fixed engaging portion is a first engaging hole 250 provided in the socket 200, and the first engaging protrusion 330 is inserted into the first engaging hole 250 to lock the connector 100.

In the above solution, in the connection state of the plug 100 and the socket 200, the plug 100 is located in the socket groove 210 of the socket 200, and the elastic engaging portion 300 provided on the plug 100 is surrounded by the socket 200, so that the elastic engaging portion is not easily touched by other objects to be unlocked, and the plug-in connection device is more reliable and safer.

Referring to fig. 2, in one embodiment of the present invention, the plug-in type connection device according to the above embodiment: one end of the elastic clamping part 300 is fixed on the plug connector 100, the other end extends in the direction away from the fixed end to form a cantilever spring sheet, the free end of the elastic clamping part 300 is the operation end 310, when the plug connector 100 and the socket connector 200 are assembled, the operation end 310 extends towards the socket 220, the extension includes the situation that the operation end 310 is positioned in the socket 210 and outside the socket 210, if the operation end 310 is positioned in the socket 210, the operation end 310 is close to the socket 220 or is flush with the socket 220, in this situation, the operation end 310 can be shifted by fingers or tools; if the operation end 310 is located outside the socket 210, the operation end 310 extends out of the socket 220, in this case, the operation end 310 is not limited by the inner space of the socket 200, that is, the operation space around the operation end 310 is enlarged, and the operation end 310 is more convenient to be detached by hand.

In the above solution, when the operation end 310 of the cantilever spring plate is acted by an external force, the deformation portion of the cantilever spring plate is mainly concentrated near the fixed end 320 of the cantilever spring plate, and other portions of the cantilever spring plate are displaced accordingly, and since the operation end 310 is far away from the fixed end 320 of the cantilever spring plate, the force applied to the operation end 310 during disassembly can easily pry the cantilever spring plate to complete unlocking. Preferably: the position (the first stop surface 331) where the cantilever spring is locked is closer to the operation end 310 than the fixed end 320 of the cantilever spring, that is, the distance between the first stop surface 331 and the operation end 310 is less than half of the length of the cantilever spring.

As can be understood with reference to fig. 2: to ensure that the plug 100 is reliably locked in the socket 210, the first engaging protrusion 330 and the second engaging protrusion 230 have a sufficient interference L1 (i.e. the overlapping area of the first stop surface 331 and the second stop surface 232 in the locked state), and if the locking is to be released, the displacement L2 generated by the cantilever spring plate driving the first stop surface 331 is greater than the interference L1. According to the above-mentioned solution, under the same acting force, the displacement generated at the position closer to the operation end 310 on the cantilever spring plate is larger, and when the position where the cantilever spring plate is locked is closer to the operation end 310 than the fixed end 320 of the cantilever spring plate, the displacement L2 generated by the cantilever spring plate driving the first stop surface 331 is also larger, the cantilever spring plate is easier to unlock, and the acting force required for unlocking the cantilever spring plate is reduced, so as to reduce the difficulty in dismounting.

In one embodiment of the present invention, the plug-in connection device according to the above embodiment: the socket 200 has a positioning groove 240 on one side, the positioning groove 240 extends inward from the socket 220, and the positioning rib 110 of the socket 100 is slidably engaged with the positioning groove 240. The following are exemplary: as shown in fig. 1, a positioning groove 240 extending inward from the insertion port 220 is disposed on a side wall of the socket 200 opposite to the second engaging protrusion 230, a positioning rib 110 slidably engaged with the positioning groove 240 is disposed on a side of the insertion unit 100 away from the first engaging protrusion 330, and the engagement between the positioning rib 110 and the positioning groove 240 guides the insertion unit 100 to be inserted into the insertion port 220 at a predetermined position, so as to avoid problems of reverse installation and wrong installation of the insertion unit 100; in addition, the positioning rib 110 on the plug 100 can also connect the plug 100 with a corresponding structural member, the plug 100, the positioning rib 110 and the structural member generally form an integrated structure through injection molding, and the positioning rib 110 increases the connection strength of the plug 100 and the structural member and is not easy to break.

In one embodiment of the present invention, the plug-in connection device according to the above embodiment: the plug 100 is a sliding fit with the socket 210. The sliding fit means that the fit clearance between the plug connector 100 and the socket groove 210 is subject to free sliding and obvious shaking does not occur, so that the plug connector 100 and the socket part 200 can be smoothly assembled and disassembled, and looseness of a corresponding structural part after installation due to relative shaking of the plug connector 100 and the socket part 200 can be avoided. The following are exemplary: referring to fig. 1, the cross section of the socket groove 210 is rectangular, two rectangular limiting plates 120 are arranged on two sides of the plug connector 100, the distance between the two limiting plates 120 is slightly smaller than the length of the socket groove 210, the width of the limiting plate 120 is slightly smaller than the width of the socket groove 210, after the assembly connection of the plug connector 100 and the socket part 200 is completed, two sides of the socket groove 210 in the length direction are respectively matched with the limiting plates 120 on two sides of the plug connector 100, the displacement of the plug connector 100 in the length direction of the socket groove 210 is limited, the two sides of the socket groove 210 in the width direction respectively stop the limiting plates 120, the displacement of the plug connector 100 in the width direction of the socket groove 210 is limited, and it is ensured that the plug connector 100 and the socket part 200 cannot obviously shake after being connected. The above scheme is for convenience of explaining the sliding fit relationship between the plug 100 and the socket groove 210, the fit shape of the plug 100 and the socket groove 210 is not particularly limited, the cross section of the socket groove in other embodiments may be circular or elliptical, and the plug shape may be matched with the cross section.

Referring to fig. 4, the plug-in type connection device according to one embodiment of the present invention includes a plug 100 and a socket 200, the socket 200 is provided with a socket 210 and a socket 220, the plug 100 is inserted into or pulled out of the socket 210 through the socket 220, the socket 200 is provided with an elastic engaging portion 300, the socket 200 is respectively grooved at both sides of the elastic engaging portion 300, such that the elastic engaging portion 300 can be outwardly deformed relative to the socket 200, the elastic engaging portion 300 is used for locking the plug 100 in the socket 210, the elastic engaging portion 300 has an operating end 310 extending toward the socket 220, and the operating end 310 can drive the elastic engaging portion 300 to be deformed to release the plug 100.

In order to lock the elastic engaging portion 300 and lock the connector 100 in the socket 210, the connector 100 of the present embodiment is provided with a fixed engaging portion matching the elastic engaging portion 300, which is exemplified by: the elastic engaging portion 300 is provided with a first engaging protrusion 330, the fixed engaging portion is a second engaging protrusion 230 provided on the plug 100, the first engaging protrusion 330 stops the second engaging protrusion 230 to lock the plug 100, and the stopping relationship between the first engaging protrusion 330 and the second engaging protrusion 230 in this embodiment can refer to the foregoing embodiments and is not described in detail. However, since the elastic engaging portion 300 is disposed on the socket 200, the operation end 310 of the elastic engaging portion 300 is not limited by the inner space of the socket groove 210, thereby facilitating the detachment by the operator.
