[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to restrict the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The terms “first”, “second”, “third” and the like in the present invention do not represent specific quantities and orders, but are merely used to distinguish names. Example

[0035] See also Figures 1 to 3As shown, a long-life spring clip snap-on connector comprises a male plug 1 and a female plug 2. The female plug 2 is provided with a mounting plate 10. Both ends of the lower surface of the mounting plate 10 are provided with guide blocks 11 respectively. A plug-in slot 12 is formed between the guide block 11 and the lower surface of the mounting plate 10.

[0036] It also includes an elastic sheet 3, which includes a fixed sheet 30 and a movable sheet 31 connected to the fixed sheet at one end. The fixed sheet 30 is inserted into the plug-in slot 12, and a locking hole 310 is provided on the surface of the movable sheet 31.

[0037] The sliding block 4 is slidably arranged on the upper surface of the mounting plate 10, and a driving block 40 is provided at the end of the sliding block 4 extending downward, and the driving block 40 cooperates with the movable end of the movable sheet 21.

[0038] The surface of the male plug 1 is provided with a locking boss 20. When the male plug 1 is mated with the female plug 2, the locking boss 20 fits into the locking hole of the movable sheet.

[0039] The utility model improves the connector. The specific connector is a plug-in circular connector, and rubber packages are respectively provided at both ends of the male plug and the female plug. The mounting plate forms a flat mounting area on the surface of the female plug to provide mounting space for other components. The fixing piece of the elastic piece is plugged into the plug-in groove below the mounting plate to achieve the fixation of the elastic piece and the female plug. The sliding block is located above the mounting plate and can slide along the mounting plate. During the plug-in process of the male plug and the female plug, the sliding block does not move, and the locking boss on the surface of the female plug will lift the movable piece upwards, and the connection between the movable piece and the fixing piece is achieved. When the locking cam is in the locked state, the locking cam is released and the locking cam is in the locked state, so that the locking cam is locked in the locked state.

[0040] See also Figure 4 and Figure 7As shown, the fixing sheet 30 is provided with an upturned fixing card 301, and the mounting plate 10 is provided with a fixing hole 101. When the fixing sheet is inserted and fitted into the plug-in slot, the upturned end of the fixing card abuts against the inner wall of the fixing hole, thereby further improving the connection reliability between the fixing sheet and the mounting plate and avoiding the situation where the elastic sheet is pulled out when the two plugs are pulled out. Furthermore, the fixing card of the elastic sheet is fitted into the fixing hole, and the fixing card can be pressed down by a tool to release the abutment with the fixing hole. When the elastic sheet is found to be damaged or defective, it is convenient for people to replace the elastic sheet.

[0041] The elastic sheet 3 is made of metal material and has a longer service life than the buckle made of injection molding in the prior art, thus effectively solving the problem of short service life of the prior buckle.

[0042] See also Figure 7 As shown, the movable sheet 31 includes an inclined section 311 connected to the fixed sheet, the inclined section 311 is connected to a horizontal section 312, the locking hole 310 is arranged on the horizontal section 312, the other end of the horizontal section 312 is connected to a tilting section 313, and the driving block abuts against the lower surface of the tilting section. The shape of the movable sheet is further limited here. The horizontal section is a plane, which can better fit with the surface of the female plug, thereby ensuring its locking ability to the locking protrusion of the female plug. The tilting section is in an upward tilted shape as a whole, and the driving block abuts against the lower surface of the tilting section, which makes it convenient for people to drive the deformation of the movable sheet through the sliding block, reduces the difficulty of unlocking the elastic sheet, and improves the usability of the product.

[0043] See also Figure 4 and Figure 6 As shown, at least one limiting boss 102 is provided on the upper surface of the mounting plate 10, and at least one sliding groove 41 is provided on the lower surface of the sliding block 4. A locking boss 410 is provided at the bottom of the sliding groove 41. When the movable sheet is not deformed, the locking boss of the sliding block abuts against the limiting boss on the mounting plate. When the aforementioned movable sheet is deformed, that is, the driving block of the sliding block only abuts against the lower surface of the tilting section of the movable sheet, and drives the movable sheet to tilt upward. At this time, the movable sheet is not deformed. Specifically, the lower surface of the sliding block in this embodiment is provided with two sliding grooves, and the surface of the corresponding mounting plate is provided with two limiting bosses. The provided sliding grooves and limiting bosses guide the sliding of the sliding block, and the cooperation between the limiting bosses and the locking bosses locks the sliding block in the horizontal direction, so that the sliding block will not slide out from the end of the mounting plate.

[0044] Further, see Figure 4 and Figure 5As shown, a U-shaped reinforcing plate 13 is provided around the mounting plate 10, and guide grooves 130 are respectively provided on the opposite surfaces of the U-shaped reinforcing plate 13. The side wall of the sliding block 4 is provided with a guide block 42 that cooperates with the guide groove. The guide block cooperates with the guide groove to guide the movement of the sliding block on the one hand, and to limit the sliding block on the other hand, specifically to limit the sliding block in two directions, so that the sliding block can be stably connected to the mounting plate.

[0045] See also Figure 1 and Figure 3 As shown, one end of the sliding block 4 is in an arc shape, and a slope 43 is provided on the upper surface of the sliding block 4. The arc design is consistent with the shape of the U-shaped reinforcement plate, and there will be no interference between the sharp corners of the sliding block and the U-shaped part of the U-shaped reinforcement plate, so that the sliding block has a larger movement stroke. Furthermore, the set slope makes it convenient for people to apply force, and people can drive the movement of the sliding block with a smaller force, reducing the difficulty of use.

[0046] In summary, the utility model has the following beneficial effects:

[0047] The utility model improves the structure of the connector. Firstly, the utility model improves the structure of the elastic sheet and adopts a structural design of a fixed sheet and a movable sheet. The fixed sheet is used for installing and fixing the elastic sheet, and the movable sheet is used for locking the two connectors. Secondly, the elastic sheet is made of metal material and has a good service life, thereby extending the service life of the connector and overcoming the problem of high connector use cost caused by failure of the elastic buckle in the prior art. Thirdly, the user unlocks the elastic sheet by pushing the sliding block, which is convenient for people to use.

[0048] Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
