Description

Technical Field

[0001] The invention relates to the technical field of relay socket buckles, and in particular to a self-locking buckle structure of a relay socket. Background Art

[0002] Electromagnetic relays are mainly composed of input and output parts. When a certain voltage or current is applied to the two ends of the coil, the energized coil will generate magnetic flux, which will generate attraction through the iron core, yoke, armature and a certain working air gap, thereby driving the moving reed to connect the static reed to realize the on / off and switching of the circuit.

[0003] Some relays need to be installed on standard electrical installation rails. A socket is provided between the relay and the electrical installation rail. The relay is installed in the socket and then connected to the rail through the socket. In the prior art, the buckles of the relay sockets are all self-resetting buckles. When the buckle is opened, the socket is separated from the rail and the buckle automatically resets. When reinstalling, it is necessary to press down hard to overcome the elastic force of the reset spring to make the buckle slide and jam the rail, which makes the installation complicated and inconvenient. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a self-locking buckle structure of a relay socket, which overcomes the shortcomings of the prior art and utilizes the sum of the deformation force and thrust of the reset rocker arm to reset the self-locking block, so that the self-locking block is clamped in the first limit notch, thereby clamping the guide rail through the guide rail clamp block, thereby achieving the purpose of easily installing and firmly fixing the buckle body of the relay socket and the guide rail.

[0007] Preferably, the second limiting notch is located at the outermost side of the socket cover plate, the first limiting notch and the second limiting notch are separated by a limiting block, the side surface of the self-locking block away from the guide rail block is set as a first guide bevel, and the side surface of the first limiting notch close to the limiting block is set as a second guide bevel, and the first guide bevel matches the second guide bevel.

[0008] Preferably, a gap is provided between the self-locking card block and the buckle body to ensure that the self-locking card block has sufficient space for deformation.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention and the accompanying drawings.

[0023] Embodiment 1, as Figures 1 to 4 As shown, a self-locking buckle structure of a relay socket comprises a buckle body 1 and two socket cover plates 2, wherein the socket cover plates 2 respectively cover both sides of a relay socket housing 3, and both ends of the rear side of any socket cover plate 2 are respectively provided with a first protrusion and a second protrusion backward, the buckle body 1 is arranged between the first protrusions on the rear sides of the two socket cover plates 2, and a sliding pair in a straight line direction is arranged between the buckle body 1 and the first protrusions, and a self-locking block 4 is respectively provided on both sides of the buckle body 1 through a cantilever beam structure, and the buckle body 1 is provided with a plurality of self-locking blocks 4. A reset opening 5 is provided between the socket cover plate 2, and a reset swing rod 6 is connected to the reset opening 5 through an elastic arm. A first limiting notch 7 and a second limiting notch 8 are respectively provided in any first protrusion, and the first limiting notch 7 and the second limiting notch 8 are adjacent to each other through a step. The shape of the self-locking block 4 matches the first limiting notch 7 and the second limiting notch 8 respectively. A reset hole 9 is provided in the middle of the socket cover plate 2, and the reset swing rod 6 matches the reset hole 9; a guide rail block 10 is provided at one end of the buckle body 1 close to the center of the relay socket housing 3. The buckle body 1 bites the relay socket housing 3 on the guide rail 11 through the guide rail block 10 and the second protrusion.

[0024] When in use, when the self-locking block 4 slides into the second limiting notch 8, the guide rail block 10 is separated from the guide rail 11. At this time, the two self-locking blocks 4 are clamped and fixed to the side surfaces of the second limiting notch 8 to prevent the buckle body 1 from returning to its original position under the action of the reset rocker 6; when the relay socket housing 3 is placed on the guide rail 11, the self-locking blocks 4 are pressed toward each other to disengage the self-locking blocks 4 from the second limiting notch 8; at the same time, the buckle body 1 is pushed toward the second protruding portion, and reset under the reaction force of the deformation of the reset rocker 6, so that the self-locking block 4 is clamped in the first limiting notch 7, thereby clamping the guide rail 11 through the guide rail block 10, thereby achieving the purpose of easily installing and firmly fixing the buckle body 1 and the guide rail 11 of the relay socket.

[0025] like Figure 5 As shown, when the sum of the force F1 pushing the buckle body 1 in the direction of the second protrusion and the reaction force F3 generated by the deformation of the reset rocker 6 is greater than the sum of the self-locking forces F2 of the second limiting notches 8 on both sides on the two self-locking blocks 4, the self-locking blocks 4 on both sides of the buckle body 1 can be deformed and disengaged from the second limiting notches 8, and the self-locking blocks 4 are reset by the sum of the deformation force and the thrust of the reset rocker 6; and when the buckle body 1 needs to be self-locking and the guide rail 11 can be pulled out freely, since the sum of the self-locking forces F2 of the second limiting notches 8 on both sides on the two self-locking blocks 4 is greater than the reaction force F3 generated by the deformation of the reset rocker 6, it is ensured that the two self-locking blocks 4 can be clamped and fixed with the side of the second limiting notch 8; during the whole process, the end of the reset rocker 6 is always in the reset hole 9 on the bottom surface of the socket cover 2.

[0026] Embodiment 2, as a further solution of embodiment 1, the second limiting notch 8 is located at the outermost side of the socket cover plate 2, the first limiting notch 7 and the second limiting notch 8 are separated by a limiting block, the side surface of the self-locking block 4 away from the guide rail block 10 is set as a first guiding slope, and the side surface of the first limiting notch 7 close to the limiting block is set as a second guiding slope, and the first guiding slope matches the second guiding slope. Therefore, in the process of sliding the self-locking block 4 into the second limiting notch 8, the guiding effect of the first guiding slope and the second guiding slope allows the buckle body 1 to slide more easily in the socket cover plate 2.

[0027] Embodiment 3, as a further solution of embodiment 1, a gap is provided between the self-locking block 4 and the buckle body 1 to ensure that when the buckle body 1 is lightly pressed, the self-locking block 4 has enough space required for deformation.

[0028] Embodiment 4, as a further solution of embodiment 1, the reset rocker arm 6 includes an elastic reset rod 61 and a limiting column 62, one end of the elastic reset rod 61 is fixedly connected to the side surface of the reset port 5, and the other end of the elastic reset rod 61 is connected to the limiting column 62, and the limiting column 62 matches the reset hole 9.

[0029] By opening a reset port 5 in the middle of the buckle body 1, the elastic reset rod 61 is connected to the side of the reset port 5 to ensure that the elastic reset rod 61 can have a sufficient deformation amount. At the same time, the limiting column 62 is always installed in the reset hole 9, thereby facilitating the reset action of the entire buckle body 1.

[0030] Embodiment 5, as a further solution of embodiment 1, slide rails 12 are provided below both sides of the buckle body 1, and slide grooves 13 are provided below both sides of the socket cover plate 2, and the buckle body 1 is slidably connected with the slide grooves 13 through the slide rails 12. Therefore, when the buckle body 1 is slid left and right, the slide rails 12 and the slide grooves 13 cooperate to limit the freedom of the buckle body 1 in other directions.

[0031] Embodiment 6, as a further solution of Embodiment 5, guide bosses 14 are provided on the upper sides of the two side surfaces of the buckle body 1, and limit slide grooves 15 are provided on the upper sides of the two side surfaces of the socket cover plate 2, and the guide bosses 14 are slidably connected to the surfaces of the limit slide grooves 15. The guide bosses 14 are located on the side of the self-locking block 4 close to the guide rail block 10, and the moving position of the guide bosses 14 is limited by the convex block on the side of the first limit notch 7 close to the guide rail block 10, thereby limiting the sliding distance of the entire buckle body 1, so as to prevent the buckle body 1 from sliding outward too far and exceeding the deformation of the reset rocker 6, thereby causing the reset rocker 6 to be broken and damaged.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
