[0001] The utility model relates to the field of connectors, in particular to a floating connector. Background Art

[0002] A connector generally refers to an electrical connector, whose function is to build a bridge of communication between blocked or isolated circuits within a circuit, thereby allowing current to flow and enabling the circuit to achieve its intended function.

[0003] In the prior art, when installing a connector, the distance between the client mounting panel, which is fixed to the main rubber core, and the client PCB, which is fixed to the connection terminals, is fixed. If the distance between the mounting panel and the PCB is not adjusted correctly or if there is any deviation during installation, the connector will not install properly.

[0004] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the utility model discloses a floating connector, and the specific technical solution is as follows:

[0006] The utility model provides a floating connector, comprising a main body rubber core, a female terminal, a soft connection terminal and a floating fixing piece.

[0007] The main rubber core is connected to a mounting panel.

[0008] The female terminal is clamped inside the main body rubber core, the first end of the female terminal extends outward from the first end of the main body rubber core, and the second end of the female terminal is fixedly connected to the first end of the soft connection terminal.

[0009] The second end of the flexible connection terminal is fixedly engaged with the floating fixing member, and the first end and the second end of the flexible connection terminal can move relatively close to or away from each other. The flexible connection terminal passes through the second end of the floating fixing member and is connected to a PCB board.

[0010] The floating fixing member is interference-fittedly arranged on the inner side of the second end of the main rubber core, and the floating fixing member can move back and forth relative to the main rubber core.

[0011] The distance between the mounting panel and the PCB board changes as the distance between the first end and the second end of the flexible connection terminal changes.

[0012] Furthermore, the soft connection terminal includes an elastic portion and a clamping portion.

[0013] The clamping portion includes a rod, a first boss vertically arranged on the rod, and a second boss parallel to the first boss. The first boss is arranged at the first end of the rod, and the second boss is arranged between the first end and the second end of the rod. The floating fixing member is clamped between the first boss and the second boss of the clamping portion. The width of the second boss is the same as the width of the rod.

[0014] The elastic part can be freely extended and retracted, the first end of the elastic part is fixedly connected to the second end of the female terminal, and the second end of the elastic part is fixedly connected to the first boss of the rod part.

[0015] Furthermore, the flexible connecting terminal is formed by bundling metal wires and then pressing them together to form the elastic part and the clamping part. The second end of the female terminal is provided with a wing structure, and the second end of the female terminal is crimped and fixed by the wing structure and the first end of the elastic part.

[0016] Furthermore, the first end of the floating fixing member is provided with a strip-shaped through hole extending to the second end. After the second boss passes through the strip-shaped through hole from the first end of the floating fixing member and extends out of the second end of the floating fixing member, the first boss approaches or contacts the first end of the floating fixing member, and the clamping portion is rotated 90°. The first boss and the second boss are perpendicular to the strip-shaped through hole and the floating fixing member is clamped between the first boss and the second boss.

[0017] Furthermore, the length or width of the first boss is longer than the cross-sectional shape of the strip through hole. After the second boss passes through the strip through hole, the first boss is stuck against the first end of the floating fixing member and the first boss cannot be inserted into the strip through hole.

[0018] Furthermore, the floating fixing member is also provided with a rotation hole and a bar-shaped slot.

[0019] The strip-shaped slot is provided on the end surface of the second end of the floating fixing member and is perpendicular to the strip-shaped through hole. The width of the strip-shaped slot is slightly smaller than the width of the second boss. When the second boss is rotated 90° and pressed into the strip-shaped slot, the second boss is fixed in the strip-shaped slot with an interference fit.

[0020] The rotating hole is a circular hole with the center of the second boss as the center and the maximum diagonal length of the rod as the diameter. The rotating hole passes through the first end and the second end of the floating fixing member, and the clamping part can rotate in the rotating hole.

[0021] Furthermore, among the four areas formed by the intersection of the strip through hole and the strip slot, only two areas that are spaced apart from each other are provided with support steps, and the support steps are formed by the downward depression of the end surface of the first end of the floating fixing member. The support steps are respectively connected to the strip through hole and the strip slot, and the height of the support steps gradually increases from the strip through hole to the strip slot. The support step forms a certain distance difference between the edge of one side of the strip slot and the bottom of the strip slot, thereby forming a groove-shaped structure to facilitate the second boss to be stuck in the groove, and the other side of the strip slot forms a blocking wall to prevent the second boss from rotating too much.

[0022] Furthermore, the distance between the first boss and the second boss is the distance from the support step to the first end face of the floating fixture, and the height variation range of the second boss during rotation is within the elastic deformation range of the first boss and the second boss.

[0023] Furthermore, the support step is provided with a rounded corner at the connection with the strip-shaped through hole, and a rounded corner is also provided at a corresponding position on the bottom of the second boss to facilitate the rotation of the second boss.

[0024] Furthermore, a plurality of raised anti-slip strips are symmetrically provided on the outer side wall of the floating fixing member, and the floating fixing member is interference-fitted with the main rubber core through the anti-slip strips.

[0025] The utility model has the following beneficial effects:

[0026] 1. The floating connector provided by the utility model adopts crimping to fix the female terminal and the soft connection terminal, which has a strong gripping force and is not easy to disconnect.

[0027] 2. The floating connector provided by the present invention has an elastic portion on the flexible connection terminal that is formed by pressing a metal wire, which can have a large deformation amount, facilitating the movement and expansion of the PCB board, thereby preventing the distance error between the PCB board and the mounting panel.

[0028] 3. The floating connector provided by the present invention adopts a combination of a strip through hole and a strip slot on the floating fixing part. After rotating the soft connection terminal, the soft connection terminal and the floating fixing part can be positioned and clamped together. When the soft connection terminal moves, the floating fixing part can be driven to move together.

[0047] The utility model discloses a floating connector, referring to Figures 1 to 6 , including a main body rubber core 10, a female terminal 20, a soft connection terminal 30 and a floating fixing part 40.

[0048] The main rubber core 10 is connected to a mounting panel 50. The female terminal 20 is secured within the main rubber core 10. The first end of the female terminal 20 extends outward from the first end of the main rubber core 10, and the second end of the female terminal 20 is fixedly connected to the first end of the flexible connector 30. The second end of the flexible connector 30 is secured to the floating fixture 40, allowing the first and second ends of the flexible connector 30 to move toward or away from each other. A PCB 60 is connected to the flexible connector 30 through the second end of the floating fixture 40. The floating fixture 40 is interference-fitted inside the second end of the main rubber core 10 and is movable relative to the main rubber core 10. The distance between the mounting panel 50 and the PCB 60 varies with the distance between the first and second ends of the flexible connector 30, thereby resolving the problem of distance errors between the mounting panel 50 and the PCB 60 during installation.

[0049] In one embodiment, the flexible connector terminal 30 includes an elastic portion 31 and a clamping portion 32. The clamping portion 32 includes a rod 321, a first boss 322 perpendicular to the rod 321, and a second boss 323 parallel to the first boss 322. The first boss 322 is disposed at the first end of the rod 321, and the second boss 323 is disposed between the first and second ends of the rod 321. The floating fixture 40 is clamped between the first and second bosses 322 and 323 of the clamping portion 32. The width of the second boss 323 is the same as the width of the rod 321. The elastic portion 31 is capable of free expansion and contraction. The first end of the elastic portion 31 is fixedly connected to the second end of the female terminal 20, and the second end of the elastic portion 31 is fixedly connected to the first boss 322 of the rod 321.

[0050] Preferably, the flexible connector 30 is formed by bundling metal wires and then pressing them together to form the elastic portion 31 and the clamping portion 32. The second end of the female terminal 20 is provided with a wing structure, which is crimped and secured to the first end of the elastic portion 31 by the wing structure. The wing structure wraps around the first end of the elastic portion 31 and then presses it together, ensuring a strong bond between the female terminal 20 and the elastic portion 31. The remaining portion of the elastic portion 31 can be bent freely to control the relative displacement of the two ends of the flexible connector 30.

[0051] In one embodiment, the first end of the floating fixing member 40 is provided with a strip-shaped through hole 41 extending to the second end. After the second boss 323 extends from the first end of the floating fixing member 40 through the strip-shaped through hole 41 to the second end of the floating fixing member 40, the first boss 322 approaches or contacts the first end of the floating fixing member 40, and the clamping portion 32 is rotated 90°. The first boss 322 and the second boss 323 are perpendicular to the strip-shaped through hole 41 and clamp the floating fixing member 40 between the first boss 322 and the second boss 323.

[0052] Preferably, the length or width of the first boss 322 is longer than the cross-sectional shape of the strip through hole 41. After the second boss 323 passes through the strip through hole 41, the first boss 322 is stuck to the first end of the floating fixing member 40, and the first boss 322 cannot be inserted into the strip through hole 41.

[0053] In one embodiment, the floating fixing member 40 is further provided with a rotation hole (not shown) and a strip-shaped slot 42 .

[0054] The strip slot 42 is arranged on the end surface of the second end of the floating fixing member 40 and the strip slot 42 is perpendicular to the strip through hole 41. The width of the strip slot 42 is slightly smaller than the width of the second boss 323. When the second boss 323 is rotated 90° and pressed into the strip slot 42, the second boss 323 is fixed in the strip slot 42 by interference fit.

[0055] The rotating hole is a circular hole with the center of the second boss 323 as the center and the maximum diagonal length of the rod 321 as the diameter. The rotating hole passes through the first end and the second end of the floating fixing member 40, and the clamping portion 32 can rotate in the rotating hole.

[0056] In one embodiment, among the four areas formed by the intersection of the strip through hole 41 and the strip slot 42, only two areas that are spaced apart from each other are provided with support steps 43. The support steps 43 are formed by the downward depression of the end surface of the first end of the floating fixing member 40. The support steps 43 respectively connect the strip through hole 41 and the strip slot 42. The height of the support step 43 gradually increases from the strip through hole 41 to the strip slot 42. The support step 43 forms a certain distance difference between the edge of one side of the strip slot 42 and the bottom of the strip slot 42, thereby forming a groove-shaped structure to facilitate the second boss 323 to be stuck in the groove. The other side of the strip slot 42 forms a blocking wall to prevent the second boss 323 from rotating too much.

[0057] In one embodiment, the distance between the first boss 322 and the second boss 323 is the distance from the support step 43 to the first end face of the floating fixing member 40, and the height variation range of the second boss 323 during rotation is within the elastic deformation range of the first boss 322 and the second boss 323.

[0058] Preferably, the support step 43 is provided with a rounded corner at the connection with the strip-shaped through hole 41 , and a rounded corner is also provided at a corresponding position of the bottom of the second boss 323 to facilitate the rotation of the second boss 323 .

[0059] In one embodiment, a plurality of raised anti-slip strips 44 are symmetrically provided on the outer side wall of the floating fixing member 40 , and the floating fixing member 40 is interference-fitted with the main rubber core 10 via the anti-slip strips 44 .

[0060] The working principle of this utility model is:

[0061] The first end of the elastic portion 31 on the flexible connecting terminal 30 and the second end of the female terminal 20 are crimped and fixed. After fixation, the female terminal 20 and the flexible connecting terminal 30 are inserted into the interior of the main rubber core 10 from one end of the main rubber core 10. The female terminal 20 and the main rubber core 10 are clamped and fixed. The floating fixing piece 40 continues to be inserted from the end of the main rubber core 10. After the second protrusion 323 of the clamping portion 32 passes through the bar through hole 41 on the floating fixing piece 40, the clamping portion 32 is rotated 90°, and the second protrusion 323 is pressed into the bar clamping groove 42 and clamped. The floating fixing piece 40 is clamped between the first protrusion 322 and the second protrusion 323. The floating fixing piece 40 expands and contracts with the expansion and contraction of the clamping portion 32. The flexible connecting terminal 30 is formed as a whole by pressing a bundle of metal wires. The elastic portion 31 is set to an appropriate length as needed. The metal wire 3 at the elastic portion 31 can be bent arbitrarily to determine the expansion and contraction range of the clamping portion 32, thereby ensuring the range of adjustable distance between the mounting panel and the PCB board.
