[0038] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The following embodiments and features in the embodiments can be combined with each other without conflict.

[0039] If there are terms involving directional indications or positional relationships in the embodiments of the present application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a certain specific posture; if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first", "second", etc. involved in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.

[0040] The present application embodiment provides a connector. Figures 1 to 3 As shown, the connector includes a first connector 10 and a second connector 20; the first connector 10 is provided with a conductive terminal 11, and the second connector 20 is provided with a receiving hole 21 for receiving a wiring harness and an opening 25 located at the side of the receiving hole 21 and communicating with the receiving hole 21. One of the first connector 10 and the second connector 20 is provided with a limiting portion 30, and the other is provided with a matching portion 40; the matching portion 40 includes a top plate 41, two side plates 42 located on the same side of the top plate 41 and arranged oppositely, and a limiting plate 43 extending from each side plate 42 toward the other side plate 42; the limiting portion 30 includes two limiting end portions 31 arranged oppositely, and the maximum distance d1 between the side surfaces of the two limiting end portions 31 that are opposite to each other is greater than the distance d2 between the two limiting plates 43.

[0041] When the first connecting member 10 and the second connecting member 20 are assembled, the limiting portion 30 presses the limiting plate 43 along the first direction X, so that the two limiting plates 43 are deformed, so that the limiting portion 30 enters the space between the two side plates 42 and on the side of the limiting plate 43 facing the top plate 41, as shown in FIG. Figure 3 As shown; at the same time, the end portions 111 of the conductive terminals 11 respectively enter the receiving hole 21 through the openings 25 and are electrically connected to the wiring harness contained in the receiving hole 21.

[0042] In the connector provided by the embodiment of the present application, one of the first connector 10 and the second connector 20 is provided with a limiting portion 30, and the other is provided with a mating portion 40. Since the maximum distance between the sides of the two limiting end portions 31 which are away from each other is greater than the distance between the two limiting plates 43, after the first connector 10 and the second connector 20 are assembled, the limiting portion 30 enters the space between the top plate 41 and the two side plates 42 of the mating portion 40, the limiting plate 43 limits the limiting portion 30 in the space, which can effectively prevent the first connector 10 from separating from the second connector 20, thereby avoiding the first connector 10 from separating from the second connector 20. The connector 10 is separated from the second connector 20, which affects the normal operation of the light-emitting substrate including the connector; during the assembly of the first connector 10 and the second connector 20, the limiting portion 30 squeezes the two limiting plates 43 to deform them. After the limiting portion 30 passes through the gap between the two limiting plates 43, the limiting plates 43 restore their deformation. The operator can feel the vibration caused by the limiting plates 43 restoring their deformation, and can hear the sound produced by the limiting plates 43 hitting the limiting portion 30 after restoring their deformation, which helps the operator to ensure that the first connector 10 and the second connector 20 are assembled in place.

[0043] In the embodiment shown in the drawings of the present application, the first connector 10 is provided with a limiting portion 30, and the second connector 20 is provided with a matching portion 40. In other embodiments, the first connector 10 may be provided with a matching portion 40, and the second connector 20 may be provided with a limiting portion 30.

[0044] In one embodiment, the first connecting member 10 and the second connecting member 20 can be integrally formed.

[0045] In one embodiment, the mating portion 40 is made of plastic, for example, the mating portion 40 includes PC (polycarbonate). Thus, the limiting plate 43 is elastic and can be deformed when the limiting portion 30 squeezes the limiting plate 43 , and can recover its deformation after being separated from the limiting portion 30 .

[0046] In one embodiment, Figure 1 and Figure 3 As shown, the second connector 20 is provided with two receiving holes 21 and two openings 25, and each opening 25 is connected to one receiving hole 21. When the first connector 10 and the second connector 20 are assembled, the end 111 of each conductive terminal 11 enters one receiving hole 21 through one opening.

[0047] In one embodiment, Figures 4 to 6 As shown, each of the conductive terminals 11 includes a first end 111 and a second end 112, and the first end 111 and the second end 112 are exposed respectively. The second terminal 112 is used for welding with the circuit board, and the first terminal 111 is used for electrically connecting with the wiring harness, so that the wiring harness can supply power to the circuit board through the conductive terminal 11.

[0048] In one embodiment, the first connector 10 includes two conductive terminals 11 , one of the two conductive terminals 11 is a positive terminal, and the other is a negative terminal.

[0049] In one embodiment, Figures 3 to 6 As shown, when the first connector 10 is provided with a limiting portion 30 and the second connector 20 is provided with a matching portion 40, the first connector 10 further includes a supporting portion 50 located at one side of the limiting portion 30 and connected to the limiting portion 30, and the two limiting end portions 31 respectively exceed the supporting portion 50. When the connector is provided on the light-emitting substrate, the first connector 10 having the conductive terminal 11 is provided on the light-emitting substrate; the supporting portion 50 of the first connector 10 is fixed on the circuit board of the light-emitting substrate, and the limiting portion 30 is located on the side of the supporting portion 50 away from the circuit board, so that the first connector 10 and the second connector 20 can be assembled by vertically pressing the second connector, which is convenient for the assembly of the first connector 10 and the second connector 20; the setting of the supporting portion 50 can make a gap between the limiting portion 30 and the circuit board, thereby ensuring that the limiting portion 30 can smoothly enter the space between the top plate 41 and the two side plates 42 of the matching portion 40, so as to realize the assembly of the first connector 10 and the second connector 20.

[0050] Further, when the first connecting member 10 is provided with a limiting portion 30 , the conductive terminal 11 is partially located within the limiting portion 30 and the supporting portion 50 , the first end 111 is exposed on a side of the limiting portion 30 away from the supporting portion 50 , and the second end 112 is exposed on a side of the supporting portion 50 .

[0051] In one embodiment, Figure 5 and Figure 6 As shown, the first connector 10 further includes a fixing metal sheet 12, and the fixing metal sheet 12 is used for welding with the circuit board to improve the firmness of fixing the first connector 10 on the circuit board.

[0052] In one embodiment, Figure 7 As shown, the metal sheet 12 is bent, partially embedded in the support portion 50, and the end portion is exposed from the support portion 50. The exposed end portion of the metal sheet 12 is used for welding with the circuit board 12.

[0053] Furthermore, if Figure 6 As shown, the exposed end of the metal sheet 12 and the second end 112 of the conductive terminal 11 are located on opposite sides of the support portion 50. In this way, when the first connector 10 is disposed on the circuit board, the exposed end of the metal sheet 12 and the second end 112 of the conductive terminal 11 are both welded to the circuit board, so that the force on the first connector 10 is balanced, the first connector 10 is fixed more firmly on the circuit board, and the first connector 10 is prevented from warping.

[0054] In one embodiment, Figure 3 As shown, when the first connector 10 is provided with a limiting portion 30 and the second connector 20 is provided with a matching portion 40, the first end portion 111 of the conductive terminal 11 is located at the top of the limiting portion 30, the receiving hole 21 and the opening 25 are provided on the top plate 41, and the opening 25 is located on the side of the receiving hole 21 facing the limiting plate 43 and penetrates the portion of the top plate 41 located between the receiving hole 21 and the limiting plate 43. The top of the limiting portion 30 refers to the end portion where the limiting portion 30 first enters between the two side plates 42 when the first connector 10 and the second connector 20 are assembled. In this way, after the limiting portion 30 enters the space between the top plate 41 and the two side plates 42, the first end portion 111 of the conductive terminal 11 enters into the receiving hole 21 through the opening 25, thereby being electrically connected to the wiring harness accommodated in the receiving hole 21.

[0055] In one embodiment, Figure 1 and Figure 4 As shown, the limiting portion 30 includes a first surface 32 and a second surface 33 opposite to each other, and the first surface 32 is a surface of the limiting end portion 31 away from the second surface 33. After the first connecting member 10 and the second connecting member 20 are assembled, the first surface 32 faces the limiting plate 43.

[0056] In one embodiment, Figure 1 and Figure 3 As shown, the top plate 41 includes an abutting surface 411 facing the limiting plate 43, and the distance between the abutting surface 411 and the limiting plate 43 is equal to the thickness of the limiting portion 30. In this way, after the limiting portion 30 enters the space formed by the top plate 41 and the side plate 42, the surface of the limiting portion 30 facing the top plate 41, that is, the second surface 33, abuts against the abutting surface 411, and the surface of the limiting end portion 31 away from the abutting surface 411 abuts against the limiting plate 43, thereby limiting the relative movement of the first connector 10 and the second connector 20 in a direction perpendicular to the abutting surface 411, and preventing the relative movement of the two from causing the reliability of the electrical connection between the conductive terminal 11 and the cable. The distance between the abutting surface 411 and the limiting plate 43 refers to the minimum distance between the two. For example, the surface of the limiting plate 43 facing the abutting surface 411 is an inclined surface. The distance between the abutting surface 411 and the limiting plate 43 refers to the distance between the position of the limiting plate 43 closest to the abutting surface 411 and the abutting surface 411. The distance between the abutting surface 411 and the limiting plate 43 is equal to the thickness of the limiting portion 30, which means that the two are substantially equal, including the case where the two are equal and the case where the distance between the abutting surface 411 and the limiting plate 43 is slightly greater than the thickness of the limiting portion 30.

[0057] In one embodiment, the maximum distance d1 between the sides of the two limiting ends 31 that are away from each other is equal to the distance between the two side plates 42. In this way, after the limiting portion 30 enters the space in the matching portion 40, the two limiting ends 31 respectively abut against the side plates 42 located on the same side, which can limit the relative movement of the first connector 10 and the second connector 20 in the direction perpendicular to the inner side of the side plate 42, thereby ensuring the reliability of the connection between the conductive terminal 11 and the wiring harness.

[0058] In one embodiment, Figure 1 , Figure 8 and Fig. 9 As shown, at least one of the limiting plates 43 is provided with a first guide surface 431 on the side facing the other limiting plate 43, and the first guide surface 431 is an inclined surface or an arc surface, and in the direction in which the limiting plate 43 points to the side plate 42, the first guide surface 431 is inclined toward the direction close to the other limiting plate 43. In this way, during the assembly process of the first connecting member 10 and the second connecting member 20, the first guide surface 431 can guide the limiting portion 30 to enter the matching portion 40, thereby reducing the difficulty of assembling the first connecting member 10 and the second connecting member 20. Figure 1 , Figure 8 and Fig. 9 In the illustrated embodiment, the two limiting plates 43 are both provided with a first guiding surface 431 , which can further reduce the difficulty of assembling the first connecting member 10 and the second connecting member 20 . Figure 1 , Figure 8 and Fig. 9 In the embodiment described above, the first guide surface 431 is an inclined surface. In other embodiments, the first guide surface 431 may be an arc surface.

[0059] In one embodiment, Figure 1 , Figure 4 and Figure 5 As shown, at least one of the limiting end portions 31 is provided with a second guide surface 311 on a side away from the other limiting end portion 31, and the second guide surface 311 is an inclined surface or an arc surface, and in the direction from the first surface 32 to the second surface 33, the second guide surface 311 is inclined toward a direction close to the other limiting end portion 31. In this way, during the assembly process of the first connector 10 and the second connector 20, the second guide surface 311 can guide the limiting portion 30 to enter the matching portion 40, thereby reducing the difficulty of assembling the first connector 10 and the second connector 20. Figure 1 , Figure 4 and Figure 5 In the illustrated embodiment, the two limiting ends 31 of the two limiting portions 30 are both provided with a second guiding surface 311 , which can further reduce the difficulty of assembling the first connecting member 10 and the second connecting member 20 . Figure 1 , Figure 4 and Figure 5In the embodiment described above, the second guide surface 311 is an inclined surface. In other embodiments, the second guide surface 311 may be an arc surface.

[0060] In one embodiment, Figure 1 and Figure 2 , one of the first connecting member 10 and the second connecting member 20 is provided with a limiting protrusion 60, and the other is provided with a limiting hole 70 that cooperates with the limiting protrusion 60; when the first connecting member 10 and the second connecting member 20 are assembled, the limiting protrusion 60 enters the limiting hole 70 along the first direction X. In this way, the cooperation between the limiting protrusion 60 and the limiting hole 70 can limit the first connecting member 10 and the second connecting member 20 in any direction perpendicular to the first direction X, which is more helpful to prevent the first connecting member 10 from being separated from the second connecting member 20.

[0061] Furthermore, after the limiting protrusion 60 enters the limiting hole 70, the gap between each side of the limiting protrusion 60 and the inner side of the limiting hole 70 is very small, for example, about 0.025 mm on one side. In this way, the cooperation between the limiting hole 70 and the limiting protrusion 60 is more conducive to preventing the first connecting member 10 and the second connecting member 20 from moving relative to each other in a direction perpendicular to the first direction X.

[0062] In one embodiment, Figure 1 As shown, the length direction of the receiving hole 21 is the second direction Y, and the second direction Y intersects with the first direction X. In this way, when the wire harness in the receiving hole 21 is pulled along the second direction Y, the cooperation between the limiting protrusion 60 and the limiting hole 70 can offset the force acting on the wire harness, thereby preventing the first connector 10 from being separated from the second connector 20.

[0063] In one embodiment, Figures 4 to 7 As shown, a chamfered structure 61 is provided at the top of the limiting protrusion 60. The top of the limiting protrusion 60 refers to the end of the limiting protrusion 60 that first enters the limiting hole 70. By providing the chamfered structure 61 at the top of the limiting protrusion 60, it is easy to align the limiting protrusion 60 with the limiting hole 70, thereby achieving the alignment of the first connecting member 10 and the second connecting member 20, and at the same time reducing the resistance of the limiting protrusion 60 entering the limiting hole 70.

[0064] Furthermore, a chamfered structure 61 may be provided around the top of the limiting protrusion 60 .

[0065] In some embodiments, in the extension direction of the limiting protrusion 60 , the width of the chamfered structure 61 is 0.5 mm to 1.5 mm; in the direction perpendicular to the extension direction of the limiting protrusion 60 , the width of the chamfered structure 61 is 0.5 mm to 1.5 mm.

[0066] In one embodiment, Figure 7 As shown, the inner surface of the end of the limiting hole 70 for the limiting protrusion 60 to enter is provided with a chamfered structure 71. By providing the chamfered structure 71 on the inner surface of the end of the limiting hole 70 for the limiting protrusion 60 to enter, the positioning of the limiting protrusion 60 and the limiting hole 70 can be facilitated, thereby achieving the positioning of the first connecting member 10 and the second connecting member 20, and reducing the resistance of the limiting protrusion 60 entering the limiting hole 70.

[0067] Furthermore, a chamfered structure 71 may be provided around the inner surface of the end of the limiting hole 70 for the limiting protrusion 60 to enter.

[0068] In some embodiments, in the axial direction of the limiting hole 70 , the width of the chamfered structure 71 is 0.5 mm to 1.5 mm; in the direction perpendicular to the axial direction of the limiting hole 70 , the width of the chamfered structure 71 is 0.5 mm to 1.5 mm.

[0069] In one embodiment, Figure 1 , Figures 8 to 10 As shown, the second connecting member 20 includes a main body 201, the receiving hole 21 and the opening are provided in the main body 201; the second connecting member 20 also includes two gripping portions 24, and the two gripping portions 24 are located at opposite sides of the main body 201. By providing the gripping portions 24, the size of the second connecting member 20 can be increased, so that it is convenient for an operator to grip the second connecting member 20 to assemble it with the first connecting member 10.

[0070] Further, when the second connecting member 20 is provided with the matching portion 40 , the main body 201 includes the matching portion 40 , that is, the matching portion 40 is a part of the main body 201 .

[0071] In one embodiment, Figure 1 and Fig.11 As shown, the second connector 20 is further provided with a terminal retaining wall 23 located in the receiving hole 21, and the terminal retaining wall 23 is provided with a protruding structure 231, which is located in the receiving hole 21 and protrudes inward relative to the top surface of the receiving hole 21. The protruding structure 231 can cooperate with the hook structure of the wire harness to prevent the wire harness from being separated from the second connector 20.

[0072] The present application also provides a light-emitting substrate. Fig.12 and Fig.13As shown, the light-emitting substrate includes a substrate 81 and a plurality of light boards 90 located on the substrate 81; each of the light boards 90 includes a circuit board 91, a plurality of light-emitting elements 92 located on the circuit board 91, and a connector 94 described in any of the above embodiments. The first connector 10 is fixed on the circuit board 91; the light-emitting elements 92 of the same light board 90 are connected in series and are electrically connected to the conductive terminals 11 of the first connector 10. After the second connector 20 is assembled with the first connector 10, the wiring harness in the accommodation space of the second connector 20 is electrically connected to the conductive terminals 11 of the first connector 10, and the wiring harness supplies power to the light-emitting elements 92 of the light board 90.
