Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0063] Embodiment 1

[0064] As shown in Figure 1 , Figure 2 and Figure 3 , the embodiment of the present application provides a connection combination 300, which comprises a first connector 100 and a second connector 200 used in pairs. The structure of the first connector 100 and the second connector 200 will be described below respectively.

[0065] The first connector 100 can be arranged on a mounting base for electrically cooperating with the second connector 200 on the lamp side to supply power to the lamp. Of course, the first connector 100 can also be arranged on a non-mounting base. Correspondingly, the second connector 200 can be arranged on the lamp side for electrically cooperating with the first connector 100 on the mounting base.

[0066] The first connector 100 comprises a bottom end surface 110, a first electrical connection part 120 and a first magnetic element 130, wherein the first electrical connection part 120 and the first magnetic element 130 are arranged on the bottom end surface 110. The first electrical connection part 120 is used for electrically connecting with the second electrical connection part 220 on the second connector 200, and the first magnetic element 130 is used for adsorbing and aligning with the second magnetic element 230 on the second connector 200, so as to realize the guiding alignment of the first connector 100 and the second connector 200 in the circumferential direction by using the first magnetic element 130 and the second magnetic element 230, thereby smoothly realizing the electrical connection of the first electrical connection part 120 and the second electrical connection part 220, and achieving the purpose of matching and connecting the first connector 100 and the second connector 200 without repeated attempts of the user for alignment, thereby improving the assembly efficiency.

[0067] The second connector 200 comprises a top end surface 210, a second electrical connection part 220 and a second magnetic element 230, wherein the second electrical connection part 220 and the second magnetic element 230 are arranged on the bottom end surface 110. The second electrical connection part 220 is used for electrical connection with the first electrical connection part 120 on the first connector 100, and the second magnetic element 230 is used for adsorptive alignment with the first magnetic element 130 on the first connector 100, so that the first magnetic element 130 and the second magnetic element 230 are used to realize the circumferential alignment of the first connector 100 and the second connector 200, thereby realizing the electrical connection of the first electrical connection part 120 and the second electrical connection part 220, and achieving the purpose of matching connection of the first connector 100 and the second connector 200 without repeated alignment of the user, thereby improving the assembly efficiency.

[0068] In the embodiment of the present application, the arrangement positions of the first electrical connection part 120 and the first magnetic element 130 on the bottom end surface 110 can be flexible and changeable, and it is appropriate that the first magnetic element 130 can realize adsorptive alignment with the second magnetic element 230 on the second connector 200. Meanwhile, the number of the first magnetic element 130 can be one, two or three, and the number can be set according to the requirement.

[0069] The first electrical connection part 120 can be arranged in the middle of the bottom end surface 110, and the at least two first magnetic elements 130 are arranged around the first electrical connection part 120. For example, the distance between the at least two first magnetic elements 130 and the first electrical connection part 120 on the bottom end surface 110 is relatively small, that is, the first electrical connection part 120 is located at the center of the circle, and the at least two first magnetic elements 130 are located on the circumference of the circle. As a deformation, the first magnetic element 130 can be arranged in the middle of the bottom end surface 110, the first electrical connection part 120 is arranged around the first magnetic element 130, or the first electrical connection part 120 and the at least two first magnetic elements 130 are arranged on the same circumference.

[0070] Correspondingly, the arrangement positions of the second electrical connection part 220 and the second magnetic element 230 on the top end surface 210 can be flexible and changeable, and it is appropriate that the second magnetic element 230 can realize adsorptive alignment with the first magnetic element 130 on the first connector 100. Meanwhile, the number of the second magnetic element 230 can be one, two or three, and the number can be set according to the requirement.

[0071] The second electrical connection part 220 can be arranged at the middle of the bottom end surface 110, and the at least two second magnetic elements 230 are arranged around the second electrical connection part 220. For example, the at least two second magnetic elements 230 are arranged at a distance from the second electrical connection part 220 on the bottom end surface 110, that is, the at least two second magnetic elements 230 are arranged on a circumference with the second electrical connection part 220 as the center. Obviously, after the first magnetic elements 130 and the second magnetic elements 230 are attracted and positioned, the second electrical connection part 220 is coaxially arranged with the first electrical connection part 120. As a variant, the second magnetic elements 230 can be arranged at the middle of the top end surface 210, and the second electrical connection part 220 is arranged around the second magnetic elements 230. Alternatively, the second electrical connection part 220 and the at least two second magnetic elements 230 are arranged at intervals on the same circumference.

[0072] In the embodiment of the application, the first magnetic element 130 is provided with a groove on the surface away from the bottom end surface 110, and the fastener 131 extends into the groove to fix the first magnetic element 130 on the bottom end surface 110. Thus, the first magnetic element 130 can be closer to the connecting seat 500 than the fastener 131, so as to avoid interference of the fastener 131 with the attraction and positioning of the first magnetic element 130 and the second magnetic element 230.

[0073] Obviously, the first magnetic element 130 is fixed on the bottom end surface 110 by the fastener 131, and correspondingly, the second magnetic element 230 can be movably arranged on the top end surface 210 of the second connector 200, specifically, movably arranged in the direction from the first connector 100 to the second connector 200 (perpendicular to the bottom end surface 110 or the top end surface 210). Thus, after the first magnetic element 130 and the second magnetic element 230 are attracted, the bottom end surface 110 of the first connector 100 and the top end surface 210 of the second connector 200 can continue to approach each other. As a variant, the first magnetic element 130 can be movably arranged on the bottom end surface 110, and correspondingly, the second magnetic element 230 can be fixedly arranged on the top end surface 210.

[0074] In the embodiment of the application, the magnetic pole line of the first magnetic element 130 can be arranged perpendicular to the surface of the bottom end surface 110. At this time, the end of the first magnetic element 130 away from the bottom end surface 110 can be an N pole or an S pole, so as to be attracted to the second magnetic element 230 on the second connector 200. Of course, as a variant, the magnetic pole line of the first magnetic element 130 can be parallel to the surface of the bottom end surface 110. At this time, the first magnetic element 130 and the second magnetic element 230 can still be positioned by the magnetic poles.

[0075] Correspondingly, the magnetic pole line of the second magnetic element 230 can be arranged perpendicularly to the plane of the top end surface 210, and in this case, the end of all the second magnetic elements 230 away from the bottom end surface 110 can be either N-pole or S-pole, so as to be preferably attracted to the first magnetic element 130 on the first connector 100. Of course, as a variant, the magnetic pole line of the second magnetic element 230 can also be parallel to the plane of the top end surface 210, and in this case, the alignment can still be achieved by means of the magnetic poles.

[0076] In the embodiment of the present application, the first electrical connection part 120 can be a rotary structure with a rotary shaft as the rotary center, and the first electrical connection part 120 has at least two electrical connection ends coaxially arranged from inside to outside along the rotary shaft. The electrical connection end can be a receiving groove, and adjacent two receiving grooves are insulated from each other, and the opening of the receiving groove is arranged away from the bottom end surface 110. The number of electrical connection ends (receiving grooves) can be two, which are L-pole and N-pole respectively; the number of electrical connection ends can also be three, which are L-pole, N-pole and ground pole respectively; of course, it can also be more than three. The number of electrical connection ends is equal to the number of conductive terminals on the connecting seat 500. When the electrical connection end on the first connector 100 is designed as a receiving groove with electrical connection capability, see Figure 2 The first electrical connection part 120 can include a first receiving groove 121, a second receiving groove 122 and a third receiving groove 123. The edge of the first electrical connection part 120 is provided with a first receiving cavity recessed inwardly. The inner wall of the first receiving cavity forms a first insulating part in the shape of a cylinder with a certain height, a second insulating part in the shape of a cylinder parallel to the first insulating part and with the same height is arranged in the first insulating part, and a third insulating part in the shape of a cylinder parallel to the second insulating part and with the same height is arranged in the second insulating part, the first receiving groove 121 is formed in an annular shape between the first insulating part and the second insulating part, the second receiving groove 122 is formed in an annular shape between the second insulating part and the third insulating part, and the third receiving groove 123 in the shape of a circle is arranged in the center of the third insulating part. Each receiving groove has an electrode coupling part with electrical connection capability.

[0077] Correspondingly, the second electrical connection part 220 on the second connector 200 is a rotary structure with a rotary shaft as the rotary center, and the second electrical connection part 220 has at least two conductive terminals coaxially arranged from inside to outside along the rotary shaft, and the conductive terminals correspond one by one to the receiving grooves on the first connector 100. The at least two conductive terminals extend into the corresponding receiving grooves on the first connector 100 to achieve electrical connection. As a variant, at least two receiving grooves can be arranged on the second connector 200, and conductive terminals are arranged on the first connector 100, and the conductive terminals of the first connector 100 extend into the corresponding receiving grooves on the second connector 200 to achieve electrical connection.

[0078] As Figure 3The second electrical connection part 220 includes a first conductive terminal 221, a second conductive terminal 222 and a third conductive terminal 223 arranged in sequence from outside to inside, and when the first connector 100 is connected with the second connector 200, the first conductive terminal 221, the second conductive terminal 222 and the third conductive terminal 223 are respectively accommodated in the first accommodation groove 121, the second accommodation groove 122 and the third accommodation groove 123, so as to realize the electrical connection between the first electrical connection part 120 of the first connector 100 and the second electrical connection part 220 of the second connector 200.

[0079] The first conductive terminal 221 and the second conductive terminal 222 are metal rings matched with the size and shape of the first accommodation groove 121 and the second accommodation groove 122 respectively, and the third conductive terminal 223 is a metal pin matched with the size and shape of the third accommodation groove 123. Through the setting of the ring-shaped electrical connection, the contact area between the first accommodation groove 121, the second accommodation groove 122 and the third accommodation groove 123 and the first conductive terminal 221, the second conductive terminal 222 and the third conductive terminal 223 is increased, and at the same time, the safety of electricity use is improved due to the complete insulation of the first conductive terminal 221, the second conductive terminal 222 and the third conductive terminal 223 by the first insulation part, the second insulation part and the third insulation part.

[0080] The axis of the rotation shaft of the first connector 100 can be perpendicular to the plane where the bottom end surface 110 is located, and the axis of the rotation shaft of the second connector 200 can be perpendicular to the plane where the top end surface 210 is located. When the first connector 100 and the second connector 200 are assembled in pairs, the rotation shafts of the two should be collinear.

[0081] In the embodiment of the application, the first connector 100 can further include a junction box 14. The junction box 14 includes the first electrical connection part 120 and a shell 141, and the shell 141 includes wire inlet ports 142 penetrating the shell 141. The wire inlet ports 142 are used for electrically connecting external wires, and the number of the wire inlet ports 142 can be equal to the number of the accommodation grooves. When the first electrical connection part 120 has three accommodation grooves, the number of the wire inlet ports 142 is also three, and the wire inlet ports 142 are L, N and ground poles respectively. The direction of the wire inlet ports 142 can be perpendicular to the direction of the line connecting the two first magnetic elements 130 and perpendicular to the direction in which the accommodation grooves are arranged.

[0082] In the embodiment of the application, the second connector 200 can further include a first elastic member 240, and the first elastic member 240 includes a first free end 242 and a first fixed end 241.

[0083] The first fixed end 241 is connected to the top end surface 210, and the first free end 242 is connected to the second magnetic element 230. The first free end 242 can reciprocate relative to the first fixed end 241 in the direction from the first connector 100 to the second connector 200, so that the second magnetic element 230 can be close to or away from the top end surface 210. When the first connector 100 is assembled with the second connector 200, the first connector 100 gradually approaches the second connector 200, so that the first magnetic element 130 and the second magnetic element 230 are adsorbed to each other, and then the top end surface 210 can continue to move in the direction of the first connector 100 under the action of an external force. As a variant, the first magnetic element 130 can be arranged to reciprocate on the bottom end surface 110 in the direction from the first connector 100 to the second connector 200, and correspondingly, the second magnetic element 230 is fixedly arranged on the top end surface 210.

[0084] In the embodiment of the present application, on the second connector 200, the second magnetic element 230 can be arranged to protrude from the top end surface 210, that is, the second magnetic element 230 is close to the first connector 100 relative to the top end surface 210. Specifically, the second connector 200 can include a receiving column hole 211 arranged on the top end surface 210, and the second magnetic element 230 and the first elastic member 240 are received in the receiving column hole 211. The inner hole size of the receiving column hole 211 is suitable for receiving the first magnetic element 130, so that the first magnetic element 130 can also be located in the receiving column hole 211 after being adsorbed to the second magnetic element 230.

[0085] In the embodiment of the present application, the center of gravity of the first magnetic element 130 on the bottom end surface 110 can coincide with the center of gravity of the first electrical connection part 120 on the bottom end surface 110, and the center of gravity of the second magnetic element 230 on the top end surface 210 can coincide with the center of gravity of the second electrical connection part 220 on the top end surface 210, thereby realizing more stable matching connection of the first connector 100 and the second connector 200.

[0086] Of course, the bottom end surface 110 and the top end surface 210 can not be absolutely flat, and can allow a certain curvature change.

At the same time, the first electrical connection part 120 and the second electrical connection part 220 are also aligned and partially connected, and at this time, the first hanging part and the second hanging part are not connected. Due to the arrangement of the first elastic part 240, after the first magnetic element 130 and the second magnetic element 230 are adsorbed and aligned, the top end face 210 can continue to be pushed to the bottom end face 110, so that the first hanging part is inserted into the hanging groove 521 of the second hanging part to push the tongue 5221 of the sliding tongue plate 522 located in the hanging groove 521 (specifically, the pressed surface 5223 of the tongue 5221 is pushed), and the sliding tongue plate 522 is pushed by the second plate 422 of the first hanging part and moves to the tongue plate cavity 523 direction, at the same time, the window 4211 of the first plate 421 gradually extends into the hanging groove 521 from top to bottom, when the second plate 422 moves to the groove bottom of the hanging groove 521, the window 4211 of the first plate 421 also moves to the horizontal position of the sliding tongue plate 522, at this time, the sliding tongue plate 522 is reset under the action of the second elastic part 524, the tongue 5221 is reset to the hanging groove 521 through the window 4211 on the first plate 421, so as to abut against the second plate 422 in the hanging groove 521, thereby the second plate 422 is clamped between the groove bottom of the hanging groove 521 and the sliding tongue plate 522, the clamping of the first hanging part and the second hanging part is realized, that is, the mechanical fixed connection of the fixing seat 400 and the connecting seat 500 is realized. At the same time, the first electrical connection part 120 and the second electrical connection part 220 are connected in place, and the electrical connection of the fixing seat 400 and the connecting seat 500 is realized.

Then, the user continues to increase the distance between the bottom end face 110 and the top end face 210, so that the first magnetic element 130 and the second magnetic element 230 are separated, and then the connecting seat 500 is disassembled from the fixing seat 400.
