Technical Field

[0001] The invention relates to the technical field of connectors, and in particular to a lever-type double elastic arm snap connector. Background Art

[0002] For connectors that require male and female mating (such as wire-to-board connectors), after the electrical conduction between the male and female sockets is achieved, related components are still required to maintain the connection between the male and female sockets. Snap-fit ​​is the most common connection method.

[0003] The male and female seats are mostly made of plastic. In order to ensure the stability of the buckling parts, the buckling parts are generally divided into two parts: a block and a buckle. The block and the buckle are respectively arranged on the male and female seats (or the female and male seats), so as to achieve the matching effect. However, the current buckles have the following shortcomings: when the male and female seats need to be separated, the buckle needs to be turned outward to achieve the separation effect, but the plastic cannot recover after multiple deformations, resulting in the buckle being unable to be reset after multiple outward turns, so that the male and female seats cannot be buckled, reducing the stability of the connection between the male and female seats, that is, affecting the service life of the buckle. Summary of the invention

[0004] The present invention aims at solving the problems in the prior art and provides a lever-type double elastic arm snap connector, which can increase the ability of the snap to recover its deformation.

[0007] When the buckle needs to be opened, the second lever mechanism is pressed so that the fulcrum of the second lever mechanism conflicts with the first lever mechanism; then the second lever mechanism is continuously pressed to drive the snapping mechanism to flip outward through the first lever mechanism so that the buckle is separated from the clamping block.

[0011] When the second support member abuts against the first lever mechanism, the second support member corresponds to the fulcrum position of the first lever mechanism.

[0012] Furthermore, the draw hook is connected to the first lever mechanism, and the middle part of the draw hook is bent in a direction away from the first lever mechanism, and the draw hook is used to drive the first lever mechanism to evert.

DETAILED DESCRIPTION

[0025] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0026] like Figures 1 to 4As shown in the figure, a lever - type double - elastic - arm snap - on connector provided by the present invention includes a male seat 1 and a female seat 2. On both sides of the female seat 2, there are respectively provided snap - blocks 3. On both sides of the male seat 1, there are respectively provided snap - fasteners 4. The snap - fastener 4 includes a first lever mechanism 41, a second lever mechanism 42, and a snap - on mechanism 43 for snapping with the snap - block 3. The first lever mechanism 41 is arranged on the male seat 1, the second lever mechanism 42 is connected to the first lever mechanism 41, and the snap - on mechanism 43 is arranged on the first lever mechanism 41. A clearance 44 is provided between the second lever mechanism 42 and the first lever mechanism 41, and the fulcrum of the second lever mechanism 42 is located within the clearance 44. Specifically, both the snap - block 3 and the snap - fastener 4 are made of plastic, which is a conventional means in this field.

[0027] When the male seat 1 has been snapped onto the female seat 2 and when it is necessary to open the snap - fastener 4 to separate the male seat 1 from the female seat 2, first press the second lever mechanism 42 so that the fulcrum of the second lever mechanism 42 abuts against the first lever mechanism 41. Subsequently, continuously press the second lever mechanism 42. By the lever principle, the non - pressed end of the second lever mechanism 42 is lifted with the fulcrum of the second lever mechanism 42 as the pivot, thereby driving the first lever mechanism 41 to turn outwards through this non - pressed end, and further achieving the effect of driving the snap - on mechanism 43 to turn outwards so that the snap - fastener 4 is separated from the snap - block 3, enabling the male seat 1 to be detached from the female seat 2. Compared with the prior art, the present invention drives the first lever mechanism 41 to lift by pressing the second lever mechanism 42, thereby driving the snap - on mechanism arranged on the first lever mechanism 41 to turn outwards, achieving the effect of opening the snap - fastener 4. After the male seat 1 and the female seat 2 are separated, only need to release the snap - fastener 4. Under the action of the elastic force, the second lever mechanism 42 and the first lever mechanism 41 are reset simultaneously, making the snap - fastener 4 return to its original state, and the fulcrum of the second lever mechanism 42 will no longer abut against the first lever mechanism 41 and return to the suspended state. The elastic force of the second lever mechanism 42 drives the first lever mechanism 41 to be reset, enabling the present invention to still be reliably engaged with the snap - block 3 to achieve the snap - on effect after being opened multiple times, improving the service life of the present invention.

[0028] In this embodiment, the first lever mechanism 41 includes a first support member 411 and a first lever 412, the first support member 411 is connected to the male seat 1, the first lever 412 is arranged on the first support member 411, and the first support member 411 is used as a fulcrum of the first lever 412; the two ends of the first lever 412 are respectively connected to the second lever mechanism 42, and the snap-fit ​​mechanism 43 is arranged on the first lever 412; specifically, the first lever 412 includes a first pressing portion 4121 and a first lifting portion 4122 (i.e., a non-pressing end), one end of the first pressing portion 4121 is connected to one end of the first lifting portion 4122, and the first support member 411 is connected to the connection between the first pressing portion 4121 and the first lifting portion 4122; the other end of the first pressing portion 4121 is turned outward in a direction away from the male seat, and the snap-fit ​​mechanism 43 is arranged on the first lifting portion 4122.

[0029] When the buckle 4 needs to be opened, the second lever mechanism 42 needs to be pressed so that the fulcrum of the second lever mechanism 42 falls on the first lever 412. Specifically, the landing point of the fulcrum of the second lever mechanism 42 corresponds to the position of the first support member 411, so that the second lever mechanism 42 continues to be pressed at the position corresponding to the first pressing portion 4121, that is, the pressing force after pressing the second lever mechanism 42 will also act on the first pressing portion 4121, and the first lifting portion 4122 is driven to turn outward by the lever principle, thereby achieving the effect of driving the buckle and the mechanism to turn outward.

[0030] In this embodiment, the second lever mechanism 42 includes a second lever 421 and a second support member 422 used as a fulcrum of the second lever 421. The second support member 422 is arranged on an end surface of the second lever 421 close to the first lever mechanism 41. The two ends of the second lever 421 are respectively connected to the two ends of the first lever 412. The clearance gap 44 is arranged between the second lever 421 and the first lever mechanism 41, and the second support member 422 is located in the clearance gap 44. When the second support member 422 contacts the first lever mechanism 41, the second support member 422 corresponds to the fulcrum position of the first lever mechanism 41.

[0031] Specifically, the second lever 421 is provided with a hook 4221, which is connected to the first lever mechanism 41, and the middle part of the hook 4221 is bent in the direction away from the first lever mechanism 41, and the hook 4221 is used to drive the first lever mechanism 41 to turn outward; the second lever 421 includes a second pressing portion 4222 and a second tilting portion 4223, one end of the second pressing portion 4222 is connected to one end of the second tilting portion 4223, and the second support member 422 is connected to the connection between the second pressing portion 4222 and the second tilting portion 4223; the other end of the second pressing portion 4222 turns outward in the direction away from the male seat, and the hook 4221 is used to connect the second tilting portion 4223 and the first lever mechanism 41. Figure 3It can be seen that the first pressing portion 4121 and the second pressing portion 4222 are connected via the bending portion 45 , and the first lifting portion 4122 and the second lifting portion 4223 are connected via the hook 4221 .

[0032] That is, the actual working process of the present invention is as follows: when the buckle 4 needs to be opened, the second tilting portion 4223 is pressed. At this time, since the second supporting member 422 is in a suspended state, as the pressing continues, the second lever 421 will move as a whole toward the direction of the first lever 412 until the second supporting member 422 contacts the first lever 412 (specifically, contacts the connection between the first pressing portion 4121 and the first tilting portion 4122). Then, the second pressing portion 4222 is continued to be pressed. Since the second supporting member 422 is exerted at this time, and the second pressing portion 4222 is connected to the first pressing portion 4121, and the second tilting portion 4223 is connected to the first tilting portion 4122, it is achieved that pressure is applied simultaneously. The force is applied until the first pressing part 4121 and the second pressing part 4222 drive the first lifting part 4122 and the second lifting part 4223 to evert. In this process, the function of the hook 4221 is to assist in pulling the first lifting part 4122 to evert, so that the evert stroke is larger and the block 3 and the buckle mechanism 43 can be separated. After the second pressing part 4222 is released, the plastic buckle 4 will recover its deformation due to the elastic force generated by the characteristics of the plastic due to the loss of pressure. At this time, the first support member 411, the second support member 422 and the hook 4221 will rebound, especially the shape of the hook 4221 makes the rebound effect better, so that the present invention can be reset. Since the present invention is provided with the first lever mechanism 41 and the second lever mechanism 42, it has a greater force to restore the deformation, and the effect of restoring the initial position is better than that of the technology, that is, the service life of the present invention is longer. Of course, the buckle 4 made of metal can also achieve the same effect, but the buckle 4 made of metal requires a greater force to open, and the effect of restoring the initial position is slightly worse.

[0033] In this embodiment, the snap-fit ​​mechanism 43 includes a clearance groove (not shown in the figure). When the male seat 1 is snapped into the female seat 2, the block 3 is installed in the clearance groove. That is, the snap-fitting of the male seat 1 and the female seat 2 is achieved by snapping the block 3 into the clearance groove. Specifically, the end of the block 3 close to the male seat 1 is provided with an inclined surface 32, and the other end of the block 3 is provided with a buckle surface 31. When it is necessary to snap, there is no need to open the buckle 4 so that the inside of the buckle 4 can slide down along the inclined surface 32 until the block 3 is assembled into the clearance groove. At this time, the block 3 will not be separated from the clearance groove because the buckle surface 31 conflicts with the inner wall of the clearance groove, thus achieving the snap-fitting effect. Of course, the snap-fit ​​mechanism 43 can also be a fastener, that is, the snap-fitting effect is achieved by the buckle surface 31 of the block 3 and the fastener conflicting with each other.

[0034] In this embodiment, the first lever mechanism 41, the second lever mechanism 42 and the fastening mechanism 43 are integrally formed, that is, the entire male seat 1 is injection molded, ensuring stable connection between the buckle 4 and the male seat 1 and between the various mechanisms of the buckle 4.

[0035] In this embodiment, the female seat 2 includes a female housing 21 and a plurality of female terminals 22. A terminal hole 211 with the same number as the number of female terminals 22 is provided in the female seat 2, and the female terminals 22 are installed in one-to-one correspondence with the terminal holes 211; the male seat 1 includes a male housing 11 and a plurality of male terminals 12 provided in the male housing 11, and the number of male terminals 12 is the same as the number of female terminals 22; when the male seat 1 is fastened to the female seat 2, the male terminals 12 and the female terminals 22 are inserted in one-to-one correspondence to achieve electrical conduction.

[0036] Specifically, the female terminal 22 includes a body 221, a barb portion 222 and a clamping portion 223 for clamping the male terminal 12. The barb portion 222 and the clamping portion 223 are both provided on the same end face of the body 221, and the barb portion 222 is used to pierce the inner wall of the terminal hole 211 when the female terminal 22 is assembled into the terminal hole 211.

[0037] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention is disclosed above in a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art, without departing from the technical solution scope of the present invention, when making some changes or modifications using the above-disclosed technical content as equivalent change equivalent embodiments, but as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical means of the present invention shall fall within the scope of the technical solution of the present invention.
