Description

Technical Field

[0001] The utility model relates to the field technology of guide rail spotlights, in particular to a power supply connector. Background Art

[0002] Track spotlights can be moved on tracks to change the direction of illumination through the spotlight itself, which can cover a wider range and is more convenient for users to use.

[0003] However, track spotlights need to be moved. If the wires are laid in the track and directly connected to the spotlights, the track spotlight holder may squeeze the wires during the movement of the track spotlight, making the track spotlight unable to move. For this reason, a power connector is generally installed on the track. The power connector is connected to the power cord and conducts current to the track, and the track spotlight uses the current in the track for illumination.

[0004] Track spotlights may malfunction with use. In this case, users will check or replace the track lights by themselves after turning off the power switch. During this process, the track spotlights may not light up or flicker due to unstable connection with the track. Users need to turn on the power switch again and wait for the response time to discover the problem.

[0005] Track spotlights are mostly used in shopping malls, shops or trade fairs. If the damage or failure location of the track spotlight is at a stall in an exhibition, if the power needs to be cut off for replacement, the power switch needs to be turned off. Because trade fairs are temporary scene arrangements with many merchants, in order to avoid accidents caused by merchants connecting the lines randomly, the wiring is unified by the exhibition management, and it is also very common for multiple merchants to share one line.

[0006] At this time, if the power switch is turned off due to the damage of a track spotlight, most of the merchants in an area of ​​the exhibition venue may lose power. The exhibition management generally does not agree to this. However, for the merchant, the lighting level in a specific location in the stall is reduced, and the clothes or goods cannot appear dazzling under the light, which will affect the user's actual sales. Therefore, it is particularly necessary to provide a track power connector that can conveniently cut off the power. Utility Model Content

[0007] In view of this, the present invention aims to solve the deficiencies in the prior art, and its main purpose is to provide a power connector that can easily cut off the power to facilitate users to safely replace track spotlights.

[0008] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a power connector, including a box body connected to a track and an outer baffle connected to the outer end of the box body and in contact with the outer edge of the track, the inner and outer sides of the outer baffle are penetrated by a wiring opening connected to the inside of the box body; a conductive component is provided in the box body, the conductive component has an elastically displaceable abutment end, the abutment end penetrates the box body, contacts with the track and conducts electricity, a pluggable filling part is provided on the wiring opening, the filling part is connected to the conductive component through a pulling piece, the filling part is separated from the wiring opening and drives the pulling piece to drive the abutment end to produce elastic displacement, so that the abutment end is retracted into the box body.

[0009] Furthermore, the conductive component includes a spring with one end abutting against the inner wall of the box body, the other end of the spring is connected to a power socket, the power socket is connected to a power terminal, the abutting end is the terminal end of the power terminal, and the terminal end of the power terminal passes through the box body.

[0010] Furthermore, the pulling piece passes through the spring and is connected to the middle part of the power socket, and the pulling piece is made of insulating material.

[0011] Furthermore, the inner wall of the box body is provided with a guide groove located at the lower part of the spring, and the pulling member passes through the spring through the guide groove.

[0012] Furthermore, the box body includes a accommodating shell and a blocking cover, the side wall of the accommodating shell is provided with a socket, the side wall of the blocking cover is provided with a buckle, and the blocking cover is overlapped on the accommodating shell so that the buckle is plugged into the socket.

[0013] Furthermore, the buckling surfaces of the blocking cover and the accommodating shell are provided with a clamping portion, and the clamping center of the clamping portion corresponds to the outlet end of the wiring opening.

[0014] Furthermore, the clamping portion includes a clamping block and a connecting rod, and the clamping block rotates around the connecting rod.

[0015] Furthermore, a guide portion is provided in the accommodating shell. When the blocking cover is overlapped on the accommodating shell, the guide portion contacts the movement of the clamping block, so that the clamping block clamps the wire harness in the box body.

[0016] Furthermore, the filling portion includes a flexible portion, the flexible portion is plugged into the wiring opening, and an opening is provided on one side of the flexible portion.

[0017] Furthermore, a limiting portion is provided on the box body, and when the box body is inserted into the guide rail, the limiting portion abuts against the inner wall of the guide rail.

[0018] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that when the power is cut off due to the need to replace the track spotlight, the filling part and the wiring opening are separated, so that the pulling member drives the contact end of the conductive component to be stored in the box body, and the box body cannot supply power to the track, which is convenient for users to replace the track spotlight plugged in the track.

[0032] Please refer to Figure 1-4As shown, it shows the specific structure of the preferred first embodiment of the utility model, which is a power connector, including a box body 10 connected to the track and an outer baffle 70 connected to the outer end of the box body and in contact with the outer edge of the track, the inner and outer sides of the outer baffle 70 are penetrated by a wiring opening 11b connected to the inside of the box body 10; a conductive component 20 is provided in the box body 10, and the conductive component 20 has an elastically displaceable abutment end 20a, the abutment end 20a penetrates the box body 10, contacts with the track and conducts electricity, and a pluggable filling part 50 is provided on the wiring opening 11b, the filling part 50 is connected to the conductive component 20 through a pulling member 60, the filling part 50 is separated from the wiring opening 11b and drives the pulling member 60 to drive the abutment end 20a to produce elastic displacement, so that the abutment end 20a is retracted into the box body 10. Compared with the traditional power connector that needs to be locked in position after wiring to supply power, the power connector only needs to elastically reset the abutment end 20a to contact the inner wall of the track and supply power. When power needs to be cut off, only the filling part 50 and the wiring opening 11b need to be separated to allow the abutment end 20a to be stored in the box body 10. The track is then powered off, making it convenient for users to replace new track spotlights.

[0033] Specifically, when the box body 10 is inserted into a track installed on a plane, the abutting end 20a in the conductive component 20 in the box body 10 protrudes from the outer surface of the box body 10 under the action of elasticity and contacts the inner wall of the track. It should be noted that there are at least two conductive components 20, and the abutting ends 20a on the two conductive components 20 are oppositely arranged to form a positive pole and a negative pole, which supply power to the inner wall of the track after contacting the inner wall of the track. When it is necessary to replace the track spotlight in the track, the filling part 50 is pulled outward to separate the filling part 50 from the wiring opening 11b. During this process, the filling part 50 drives the pulling member 60 to move, so that the abutting end 20a is received in the box body 10 due to the elastic displacement of the conductive component 20, and does not contact the inner wall of the track, thereby cutting off the power to the track, making it convenient for users to replace the track spotlight safely. It should be noted that when the filling part 50 drives the pulling member 60 to move and receives the abutting end 20a in the box body 10, the filling part 50 does not It must be separated from the wiring opening 11b, which is specifically related to the length of the wiring opening 11b. In addition, when the filling part 50 is not separated from the wiring opening 11b, the friction between the outer wall of the filling part 50 and the inner wall of the wiring opening 11b can play a certain limiting role, thereby preventing the abutting end 20a from re-contacting the inner wall of the track due to the elastic reset of the conductive component 20, thereby preventing the user from getting an electric shock when replacing the track spotlight. Of course, the pulled-out filling part 50 can also be wrapped around other objects through the pulling piece 60, which depends on the user's own choice or the manufacturer's consideration.

[0034] like Figure 4As shown, exemplarily, the conductive component 20 includes a spring 21 with one end abutting against the inner wall of the box body 10, and the other end of the spring 21 is connected to the power socket 22, and the power socket 22 is connected to the power head 23, and the abutting end 20a is the end of the power head 23, and the end of the power head 23 penetrates the box body 10. When the track needs to be powered, the spring 21 expands under its own elastic force, pushing the power socket 22 to abut against the inner wall of the box body 10, and the power head 23 fixed on the power socket 22 protrudes to the outside of the box body 10 under the push of the spring 21, abuts against the inner wall of the track and connects to electricity. When the current in the track needs to be de-energized, the spring 21 contracts under the pull of the pulling member 60, and pulls the power head 23 to be stored in the box body 10 along with the power socket 22. The power socket 22 is made of conductive metal, and one side of the power socket 22 contains a hole. The wiring harness is inserted into the hole and locked. The locking method can be twisting of a screw or clamping, depending on the manufacturer's choice.

[0035] Specifically, the box body 10 can be directly inserted into the track without specific limiting, and the limiting can be achieved by the contact between the electrical connector 23 and the inner wall of the track. At the same time, the box body 10 can also be easily separated from the track, which is simple for users and maintainers to disassemble and replace.

[0036] like Figure 2 As shown, for example, the pull member 60 passes through the spring 21 and is connected to the middle of the power socket 22, and the pull member 60 is made of insulating material. Because the power socket 22 is connected to the charged wire bundle, the spring 21 located at one end of the power socket 22 is generally made of steel, and steel is conductive. If the pull member 60 is not made of insulating material, it is easy to burn due to contact with the current, and directly damaged. Although the pull member 60 is made of insulating material, the selected insulating material needs to have a certain degree of flexibility but cannot have stretchability. If the pull member 60 is made of a material with a stretching effect, it may result in that even if the length of the wiring port 11b is sufficient, due to the stretchable characteristics of the pull member 60, the filling part 50 still needs to be separated from the wiring port 11b to ensure that the power connection head 23 can be stored in the box body 10.

[0037] like Figure 4As shown, illustratively, the inner wall of the box body 10 is provided with a guide groove 14 located at the lower part of the spring 21, and the pulling member 60 passes through the spring 21 through the guide groove 14. Under the pulling of the pulling member 60, the spring 21 needs to have a sufficient contraction distance to allow the contact end 20a of the power connection head 23 to smoothly enter the box body 10, and the pulling member 60 can be fixed at the middle of the power connection socket 22 and the fixed end of the spring 21 in order to smoothly contract the spring 21. After the pulling member 60 is fixed to the middle of the power connection socket 22, if it passes through the gap on the spring 21, it will affect the contraction of the spring 21. For this reason, the guide groove 14 is opened on the inner wall of the box body 10, so that the pulling member 60 can be moved out from the contact end face of the box body 10 and the spring 21 by inserting the guide groove 14, so that the spring 21 can contract itself after the user pulls the power connection socket 22.

[0038] like Figure 3 As shown, the box body 10 includes a housing shell 11 and a cover 12, the side wall of the housing shell 11 is provided with a socket 11a, the side wall of the cover 12 is provided with a buckle 12a, and the cover 12 is overlapped on the housing shell 11 so that the buckle 12a is plugged into the socket 11a. When the power harness needs to be inserted into the box body 10, the buckle 12a can be pressed to move into the housing shell 11 to separate the cover 11 from the housing shell 11. At this time, the electrical connection component 20 in the housing shell 11 is exposed, and the user can insert the power harness into the housing shell 11 through the wiring port 11b, and then connect it to the electrical connection socket 22 in different guide components 20 according to the positive and negative poles of the power harness.

[0039] Exemplarily, the buckling surface of the blocking cover 12 and the containing shell 11 is provided with a clamping portion 30, and the clamping center of the clamping portion 30 corresponds to the outlet end of the wiring opening 11b. The clamping portion 30 includes a clamping block 31 and a connecting rod 33, and the clamping block 31 rotates around the connecting rod 33. The power harness is inserted into the containing shell 11 through the wiring opening 11b, and the pulling member 60 is also connected to the filling portion 50 through the wiring opening 11b. At this time, due to the plugging of the filling portion 50 and the wiring opening 11b, the filling portion 50 moves downward, which easily drives the power harness to move outward, thereby separating from the power socket 22. In order to prevent the power harness and the filling portion 50 from moving, the clamping portion 30 is provided on the blocking cover 12, and the harness entering the containing shell 11 is clamped by the clamping portion 30.

[0040] Specifically, the clamping part 30 is composed of a clamping block 31 and a connecting rod 33. The clamping block 31 can be two staggered plates, the middle of which is connected by a connecting rod 33 to form a clamp structure to clamp the power harness. It can also be four independent plates, which are spliced ​​in pairs, and the splicing parts are connected by a connecting rod 33. When the clamping part 30 is a clamping structure in which four independent plates are spliced ​​in pairs and the splicing parts are connected by a connecting rod 33, the clamping block can be moved by the resistance of the other components to the clamping part 31 to clamp the wire harness.

[0041] Specifically, a guide portion 40 is provided in the housing shell 11. When the cover 12 is overlapped on the housing shell 11, the guide portion 40 moves against the clamping block 31, so that the clamping block 31 clamps and holds the wire harness in the box body 10. After the cover 12 is overlapped with the housing shell 11, the side edge of the guide portion 40 can contact the side edge of the clamping block 31. Since the guide portion 40 is inclined, narrow at the top and wide at the bottom, the clamping block 31 can be squeezed by the guide portion 40 to tilt around the connecting rod 33 and clamp the wire harness, so as to prevent the wire harness from being separated from the power socket 22 as the filling portion 50 moves.

[0042] Specifically, the filling portion 50 includes a flexible portion 51, which is plugged into the wiring opening 11b, and an opening 52 is provided on one side of the flexible portion 51. Due to the opening 52 provided on the flexible portion 51, the flexible portion 51 can wrap the wire bundle inserted into the wiring opening 11b, and the movement of the flexible portion 51 after wrapping will not cause the wire bundle to separate from the power socket 22. In addition, the outer wall of the flexible portion 51 is tightly fitted with the inner wall of the wiring opening 11b, so that the elastic reset of the spring 21 will not pull the flexible portion 51 to move into the box body 10.

[0043] Specifically, the box body 10 is provided with a limiter 13, which contacts the inner wall of the guide rail when the box body 10 is inserted into the guide rail. The limiter 13 can be a flexible member such as rubber, and when the limiter 13 is inserted into the track with the box body 10, it can effectively limit the box body 10 from escaping from the track.

[0044] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
