Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector locking device and a connector combination. Background Art

[0002] As the integration of electronic devices continues to increase, the performance and reliability of wire connectors, as the key bridge for signal and power transmission between electronic devices, directly affect the stable operation of the entire system. Existing wire connector designs, especially those that rely on clasps to fasten wire connectors, have met basic connection requirements to a certain extent, but the problems exposed during long-term use cannot be ignored.

[0003] In traditional design, such as Figure 1 As shown, the wire connector includes a wire end connector and a board end connector. There is a compressed wire on the wire end connector. The board end connector is used to connect the wire end connector and the control board together. The two ends of the wire end connector are pressed by the horn buckle. The horn buckle, with its unique shape design, fixes the wire more firmly in the wire end connector through mechanical force, thereby ensuring good contact between the wire and the connector, and also connects the board end connector and the wire end connector together. However, with the passage of time and the influence of external environmental factors (such as temperature fluctuations, vibrations, etc.), the horn buckle material may deform due to fatigue and aging, causing its original buckling ability to gradually weaken. With the passage of time, it can no longer effectively compress the wire end connector, which in turn causes the wire to be unable to be fully compressed. The looseness of the wire will not only affect the stable transmission of the signal, but may also cause problems such as increased resistance and signal attenuation due to poor contact. In severe cases, it may even cause short circuit or open circuit failure, posing a threat to the normal operation of the entire system.

[0004] Therefore, how to prevent the loosening of the wire connector caused by the deformation of the claw buckle becomes an urgent problem to be solved. Utility Model Content

[0045] The exemplary embodiments of the present disclosure are described in more detail below in conjunction with the accompanying drawings of the specification. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0046] Embodiment 1:

[0047] A connector locking device provided in this embodiment is used in conjunction with a wire connector and is snapped onto the periphery of the wire connector to lock the wire connector. In this embodiment, the connector locking device of this embodiment will be specifically described in conjunction with the wire connector.

[0048] A connector locking device, used in conjunction with a wire connector, such as Figure 1 As shown, the wire connector includes a board-end connector 1 and a wire-end connector 2. The wire-end connector 2 is embedded in the board-end connector 1. The two are clamped together by two clasps 3. The two clasps 3 are respectively arranged at both ends of the wire-end connector 2. Figure 2 Shown is a three-dimensional schematic diagram of the wire end connector 2 (including wires).

[0049] like Figure 3 As shown, a connector locking device includes two locking device bodies 4, combined with Figure 1 As shown, the clasp 3 includes an internal portion 301 installed inside the board-end connector 1 and an external portion 302 exposed outside the board-end connector 1, and the two locking device bodies 4 are arranged opposite to each other and respectively engaged with the periphery of the external portions 302 of the two clasps 3.

[0050] The locking device body 4 includes an integrally formed anti-foolproof structure 5 and a fixing structure 6, the fixing structure 6 is covered on the outside of the anti-foolproof structure 5, and two opposite inner walls of the anti-foolproof structure 5 are respectively provided with two protrusions 7 for engaging with the external part 302. When the locking device body 4 is fixed on the wire connector, the fixing structure 6 is tightly buckled on the board end connector 1.

[0051] Specifically, if Figure 4As shown, the inner wall of the anti-fool structure 5 is divided into a first inner wall 501, a second inner wall 502 and a third inner wall 503, the second inner wall 502 and the third inner wall 503 are arranged opposite to each other, and two protrusions 7 are symmetrically arranged on the second inner wall 502 and the third inner wall 503, each protrusion 7 includes an integrally formed protrusion base 701 and a protrusion top 702, one side of the protrusion base 701 is fixedly connected to the second inner wall 502 / the third inner wall 503, and the other side is fixedly installed with the protrusion top 702, and the surface of the protrusion top 702 is an arc surface.

[0052] In this embodiment, the shape of the protrusion top 702 is spherical, and the area occupied by the protrusion top 702 on the protrusion base 701 is much smaller than the area of ​​the upper end of the protrusion base 701 .

[0053] like Figure 5 As shown, the front and back sides of the horn buckle 3 are symmetrical to each other, and both the external part 302 and the internal part 301 have a front and a back side. Figure 5 The side shown is the front side, and the back side is the reverse side;

[0054] A slide groove 8 is provided on the front and back sides of the external part 302. The opening of the slide groove 8 is set on the side away from the wire end connector 2. The width of the slide groove 8 is adapted to the width of the raised base 701. When the locking device body 4 is engaged on the periphery of the external part 302, the slide groove 8 and the raised base 701 are clearance-matched.

[0055] like Figure 4 As shown, a guide slope 703 for sliding into the slide groove 8 is also provided on one side of the protruding base 701 away from the first inner wall 501. During implementation, the guide slope 703 is aligned with the opening of the slide groove 8, and the opening of the slide groove 8 is also provided with a notch slope 12. Under the interaction between the guide slope 703 and the notch slope 12, the protruding portion 7 can slide smoothly into the slide groove 8, thereby achieving the engagement between the locking device body 4 and the external portion 302.

[0056] like Figure 5 As shown, the front and back surfaces of the built-in portion 301 are both provided with first protrusions 9 for engaging with the board-end connector 1;

[0057] The first protrusion 9 is also connected to a second protrusion 10 for controlling the rotation angle of the horn buckle 3 , and the thickness of the second protrusion 10 is smaller than the thickness of the first protrusion 9 .

[0058] Combination Figure 6 As shown, the second protrusion 10 is located in the groove 13 of the board-end connector 1, and the second protrusion 10 swings within the range of the groove 13, so that the horn buckle 3 can move within the swinging range of the second protrusion 10 in the board-end connector 1 with the position of the first protrusion 9 as the origin.

[0059] like Figure 5As shown, the bottom of the slide groove 8 is also provided with two first grooves 801 corresponding to the shape of the raised top 702, the two first grooves 801 are connected by the second groove 802, the diameter of the first groove 801 is greater than the width of the second groove 802, the central axis of the second groove 802 coincides with the central axis of the slide groove 8, and the second groove 802 is in the shape of a long strip.

[0060] After the protrusion 7 slides into the slide groove 8, the protrusion top 702 can be respectively engaged in two first grooves 801 at different positions, so that the locking device body 4 has two fixed points in the external part 302. When the protrusion top 702 is located in the upper first groove 801, the locking device body 4 is in an unlocked state and cannot restrict the movement of the clasp 3; when the protrusion top 702 passes through the second groove 802 and stays in the lower first groove 801, the locking device body 4 is in a locked state, which can restrict the movement of the clasp 3 and fix the clasp 3.

[0061] like Figure 4 As shown, three inclined surfaces are also provided on the first inner wall 501, which are the first inclined surface 504, the second inclined surface 505 and the third inclined surface 506 from top to bottom. The three inclined surfaces have the same inclination direction. When the locking device body 4 is fixed on the wire connector, the first inclined surface 504 conflicts with the edge of the horn buckle 3.

[0062] The inclination angle of the first inclined surface 504 is complementary to the inclination angle of the edge of the horn buckle 3 , and the first inclined surface 504 is just completely fitted with the edge of the horn buckle 3 when engaged.

[0063] The fixed structure 6 includes a fourth inner wall 601 and a fifth inner wall 602 and a sixth inner wall 603 which are perpendicular to the fourth inner wall 601. The fifth inner wall 602 and the sixth inner wall 603 are arranged opposite to each other. Figure 7 As shown, the positions of the second bevel 505 and the third bevel 506 coincide with the range of the fourth inner wall 601, which is equivalent to the fourth inner wall 601 overlapping with the lower position of the first inner wall 501; there is an angle between the second bevel 505 and the third bevel 506 towards the horn buckle 3.

[0064] In this embodiment, the acute angle formed by the second inclined surface 505 and the first inner wall 501 is greater than the acute angle formed by the third inclined surface 506 and the fourth inner wall 601 .

[0065] The locking device body 4 of the present embodiment is made of plastic material. After the locking device body 4 is engaged with the buckle 3, the gap between the second bevel 505 and the third bevel 506 and the edge of the buckle 3 can be compensated by the deformation caused by the expansion and contraction of the fixing structure 6 itself, so that the second bevel 505 and the third bevel 506 can also be tightly attached to the edge of the buckle 3, generating a thrust on the buckle 3, prompting it to clamp in the direction of the wire end connector 2.

[0066] like Figure 4 As shown, a snap-in surface 11 is extended from one end of the fifth inner wall 602 and the sixth inner wall 603 that is not connected to the fourth inner wall 601 respectively. The snap-in surface 11 is parallel to the fourth inner wall 601. The snap-in surface 11 abuts against the edge of the board-end connector 1 to fix the locking device body 4 on the wire connector to prevent the locking device body 4 from detaching from the wire connector in the horizontal direction.

[0067] In this embodiment, the function of the locking surface 11 is to prevent the locking device body 4 from detaching in the horizontal direction; and the locking between the protrusion 7 and the slide groove 8 is to prevent the locking device body 4 from detaching in the vertical direction; the first inclined surface 504, the second inclined surface 505 and the third inclined surface 506 can generate a thrust on the horn buckle 3, prompting it to fasten the wire end connector 2. Through the forces generated by the above three structures, the locking device body 4 is firmly fixed on the wire connector and the horn buckle 3 and the wire are locked.

[0068] The implementation principle of this embodiment is: assemble the clevis buckle 3 and the board-end connector 1. At this time, the clevis buckle 3 has a certain range of movement. Align the protrusion 7 of the locking device body 4 with the opening of the slide groove 8 of the clevis buckle 3 to engage. The locking device body 4 fixes the clevis buckle 3 and the board-end connector 1 together. Figure 8 As shown, the claw buckle 3 is immobilized.

[0069] The board-side connector 1 assembled as above is plated (the control board 14 is installed), and then the line-side connector 2 is installed in the plate-side connector 1 after the plate is plated. The installation process is as follows: Fig. 9 As shown, the locking device body 4 is pulled upward to unlock, and the protruding top 702 slides from the first groove 801 below through the second groove 802 and stays in the first groove 801 above; Fig.10 As shown, open the two side horn buckles 3 to both sides; Fig.11 As shown, insert the line end connector 2 into the board end connector 1, and then snap the claw buckle 3 back into place; Fig.12 As shown, the locking device body 4 is pulled down to return the protruding top 702 to the first groove 801 below, thereby completing the assembly of the locking device body 4 and the wire connector.

[0070] Embodiment 2:

[0071] The connector assembly provided in this embodiment is different from the above-mentioned embodiment 1 in that it also includes a wire connector used in conjunction with the connector locking device and two clevis buckles 3;

[0072] The wire connector includes a board-end connector 1 and a wire-end connector 2 embedded in the board-end connector 1. The board-end connector 1 is engaged with the wire-end connector 2 through two clevis buckles 3. Two locking device bodies 4 are respectively engaged with the periphery of the two clevis buckles 3 and fixed on the board-end connector 1.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
