Referring to fig. 1 to 8, a connection structure of a male plug and a female plug according to an embodiment of the present invention includes a male plug 100 and a female plug 200, wherein a boss 110 is disposed at one end of the male plug 100, an installation cavity 210 is disposed at one end of the female plug 200, and the boss 110 is in insertion fit with the installation cavity 210; an elastic member 120 is arranged on the side wall of one end of the male plug 100 close to the boss 110, a buckle 130 is arranged on the side wall of the elastic member 120, and an inclined downward inclined surface 131 is arranged at one end of the buckle 130 close to the boss 110; one end of the female plug 200 is convexly provided with a connecting plate 220, the connecting plate 220 is provided with a guide groove 230 for passing through the elastic element 120, and the side wall of the guide groove 230 is recessed outwards to form a clamping groove 221 matched with the buckle 130. Compared with the prior art, the embodiment of the present invention arranges the elastic member 120 on the side wall of the end of the male plug 100 close to the boss 110, the side wall of the elastic member 120 is provided with the buckle 130, and the buckle 130 is provided with the inclined plane 131; one end of the female plug 200 is convexly provided with a connecting plate 220, the connecting plate 220 is provided with a guide groove 230, and the side wall of the guide groove 230 is provided with a clamping groove 221. During connection, the male plug 100 is inserted into the female plug 200 in alignment with the female plug, the lower end of the connecting plate 220 abuts against the inclined surface 131 of the buckle 130, so that the elastic part 120 is pressed to deform downwards and is inserted into the female plug 200 under the guidance of the guide groove 230, when the buckle 130 is inserted into a position corresponding to the clamping groove 221, the downward force applied to the upper end of the buckle 130 is removed, the elastic part 120 is elastically restored to drive the buckle 130 to move upwards, and the buckle 130 is connected with the clamping groove 221 in a matched manner, so that the male plug 100 and the female plug 200 are fixedly connected and are fastened and are not easy to loosen; when needing to dismantle, operating personnel only need the application of force to press down elastic component 120 for elastic component 120 warp, drives buckle 130 and breaks away from draw-in groove 221, outwards extract again can, the dismantlement process need not with the help of appurtenance, and the dismouting is more convenient, and not fragile. Specifically, the height of the lowest position of inclined plane 131 is slightly less than the height of the lower end face of connecting plate 220, so that in the process of connection, the lower extreme of connecting plate 220 is inserted into inclined plane 131 smoothly, and with the lower end face butt of connecting plate 220, and transition gradually to the upper end face of buckle 130 and the lower end face butt of connecting plate 220, thereby make accurate the inserting of buckle 130 to draw-in groove 221 position and cooperate, only need aim at the grafting can be fixed with the connection that realizes male plug 100 and female plug 200, it is more simple and convenient to operate.

As shown in fig. 3 and 5, preferably, one end of the elastic member 120 is fixed to the male plug 100, and the other end is disposed obliquely upward away from the boss 110, and the latch 130 is connected to the middle of the sidewall of the elastic member 120. By obliquely arranging the elastic member 120, after the insertion is completed, the height of the free end of the elastic member 120 is higher than or equal to the height of the upper end face of the connecting plate 220, so that an operator can conveniently press the elastic member 120 downwards when detaching, and the buckle 130 is separated from the clamping groove 221; moreover, the elastic member 120 is obliquely arranged, and a certain included angle is formed between the elastic member 120 and the side wall of the male plug 100, so that the elastic member 120 drives the buckle 130 to be completely separated from the clamping groove 221 in the process of pressing down the elastic member 120.

To be further described, the free end of the elastic element 120 is convexly provided with the pressing portion 121, the pressing portion 121 provides a force application portion for an operator, when detaching, the operator only needs to press the force application portion downwards with a thumb, and pulls the female plug 200 outwards at the same time, so that the male plug 100 and the female plug 200 can be separated, and the operation is simple and convenient; the lower extreme of connecting plate 220 is provided with the chute 240 with elastic component 120 assorted, and after the grafting is accomplished, the stiff end of elastic component 120 inlays the dress in chute 240, and the right-hand member lateral wall of pressing the portion 121 and the inner wall butt of guide way 230 further improve the fastening nature that public plug 100 and female plug 200 are connected, difficult not hard up.

Preferably, the width of the pressing part 121 is smaller than the width of the guide groove 230 by 0.3mm to 0.5 mm. Preferably, the thickness is 0.4mm, and a gap is formed between the pressing portion 121 and the guide groove 230, so that the pressing portion 121 can smoothly pass through the guide groove 230 during the connection process, and when the buckle 130 is inserted into the position corresponding to the slot 221, the elastic member 120 is elastically restored, and the pressing portion 121 is driven to move upwards to pass through the guide groove 230 and be arranged outside the connecting plate 220, so that an operator can press the connecting plate during the detachment process. The longitudinal direction means the left-right direction, and the width direction means the front-back direction.

Preferably, the snap 130, the elastic member 120, the pressing part 121, and the male plug 100 are integrally molded for convenience of manufacture. The integrated forming can also reduce the assembly process, save the assembly time and cost, reduce the error produced in the assembly process and improve the quality of the product.

As shown in fig. 4 and 6, preferably, two snaps 130 are symmetrically arranged at both sides of the elastic member 120, and the catching grooves 221 correspond to the snaps 130 one by one. With this arrangement, the male plug 100 can be prevented from swinging back and forth relative to the female plug 200, and the fastening performance of the connection can be further improved.

As shown in fig. 2, 5 and 8, preferably, the lower end of the male plug 100 is provided with a clamping portion 150, and the female plug 200 is correspondingly provided with a clamping groove, and the clamping groove is in fit connection with the clamping portion 150. By matching the clamping groove with the clamping part 150, the circumferential freedom degree of the male plug 100 relative to the female plug 200 can be limited, the male plug 100 is prevented from rotating relative to the female plug 200, and the connection tightness is further improved; the cooperation of joint groove and joint portion 150 also plays the effect of a direction, and joint portion 150 is along the accurate cooperation of inserting of joint groove, also makes the accurate connection of male joint and female joint.

As shown in fig. 2, 4 and 6, preferably, the side walls of the male plug 100 and the female plug 200 are provided with anti-slip grooves 310, and the anti-slip grooves 310 can prevent hands of an operator from sweating, so that the male plug 100 and the female plug 200 are not convenient to disassemble and assemble, and the disassembly and assembly convenience is further improved.

As shown in fig. 4 and 6, preferably, the side walls of the male plug 100 and the female plug 200 are provided with indication arrows 320. The indication arrow 320 indicates the direction for the operator, which plays the role of fool-proofing, so that the operator can connect the male plug 100 and the female plug 200 conveniently.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and those skilled in the art can make various modifications and variations; any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
