Description

Technical Field

[0001] The present invention relates to the technical field of furniture lighting, and specifically to a conductive structure based on the combination of contact points and contact lines and its installation method. Background Art

[0002] With the development of customized furniture, internal lighting for wardrobes has gradually become a standard configuration. A common way of lighting inside the cabinet is to install a light strip at the bottom of the shelf, and electrical connection needs to be achieved between the side panel and the shelf. In the prior art, conductive strips are mostly installed vertically on the side panel, and power-taking terminals are provided at the ends of the shelf, and power is taken through the contact between the terminals and the conductive strips.

[0003] However, the existing conductive structure has the following deficiencies: Since the conductive strips are usually exposed on the surface of the side panel, they are easily accidentally touched by metal zippers, metal hangers, etc. on clothes, there is a risk of short circuit or electric shock, so additional insulating rubber strips need to be added, but the rubber strips are prone to aging and affect the assembly efficiency; in addition, when installing the shelf, the alignment accuracy requirements for the power-taking terminals and the conductive strips are relatively high. If the installation position of the shelf is deviated, it is easy to cause poor contact; finally, the frictional resistance between the conductive strip and the terminal is relatively large, and it is not smooth enough when installing or disassembling the shelf, and the contact surface may fail due to wear after long-term use.

[0004] Therefore, the present invention proposes a new conductive structure based on the combination of contact points and contact lines and its installation method to solve the above problems. Summary of the Invention

[0005] (1) Technical Problems to be Solved The present invention aims to provide a conductive structure and installation method with reliable conductivity, convenient installation, no need for additional insulating rubber strips, and having self-guiding and fine-tuning functions, which is particularly suitable for lighting power-taking of adjustable shelves inside wardrobes.

[0012] Preferably, the conductive terminal further includes a wire electrically connected to the contact post.

[0013] Preferably, the contact terminal is an elastic contact or a rigid contact piece.

[0014] Preferably, the conductive strip is vertically installed on the cabinet column or side panel, and the surface of the conductive strip is flush with the surface of the cabinet column or side panel.

[0015] The installation method based on the conductive structure of the contact point and contact wire combination described above includes the following steps: Step 1: Pre-process the conductive strip, connector, and conductive terminals; Step 2: Install the corresponding number of connectors into the conductive strip according to the number of layers, so that the slider is placed in the groove and the contact terminal abuts against the metal strip; Step 3: Vertically install the conductive strip into the preset mounting groove of the cabinet column or side panel, and make the surface of the conductive strip flush with the surface of the column or side panel; Step 4: Machining a fixing groove and a wire groove on the end face of the shelf, machining a light strip groove on the bottom of the shelf, inserting the conductive terminal into the fixing groove so that one side of the contact post is flush with the end face of the shelf, placing the wire into the wire groove, snapping the light strip into the light strip groove and connecting it to the wire.

Specific Embodiment

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-7 , the present invention provides a technical solution: a conductive structure based on the combination of contact points and contact lines, including: A conductive bar 1, a connecting seat 2, and a conductive terminal 3; The conductive bar 1 includes an insulating fixed bar 101, and the fixed bar 101 is made of plastic or rubber insulating material.

[0023] A chute 102 with a "convex" cross-section is provided along the length direction of the fixed bar 101. On both sides of the opening of the chute 102, metal bars 103 are fixed in parallel along the length direction. The metal bars 103 are copper bars or aluminum bars. The two ends of the metal bars 103 are 1 - 10 cm away from the end face of the fixed bar 101 to avoid scratching. Card slots 104 for fixing are provided on both sides of the fixed bar 101 for connecting and installing with the column 4 of the aluminum alloy profile, and can be directly snap-fixed. A guiding groove 105 is provided on the surface of the chute 102, and the cross-section of the guiding groove 105 is semi-circular.

[0024] The connecting seat 2 includes a slider 201 and a jack 203. The slider 201 is injection-molded from nylon material. The slider 201 is slidably arranged in the chute 102. A first contact terminal 202 that contacts and is electrically connected to the metal bar 10 is provided on the slider 201. The first contact terminal 202 is an elastic contact point or a rigid contact piece, and protrudes 0.5 mm above the surface of the slider in the natural state for contacting the metal bar 103.

[0025] The jack 203 is arranged on the surface of the slider 201. The jack 203 is a round hole. A second contact terminal 204 that is electrically connected to the first contact terminal 202 is provided in the jack 203. The second contact terminal 204 is a copper spring ejector pin.

[0026] The slider 201 is provided with a guide seat 205 that mates with the guide groove 105. The guide seat 205 includes a cylinder 2051, inside which is a cylindrical cavity 2053. A ball bearing 2054 and a spring 2055 are housed within the cylindrical cavity 2053. Part of the ball bearing 2054 protrudes from the cylinder 2051 and is placed within the guide groove 105. The spring 2055 is positioned between the ball bearing 2054 and a fixing plate 2052 of the cylinder 2051. The diameter of the opening end of the cylindrical cavity 2053 is slightly smaller than the diameter of the ball bearing. A narrowing process prevents the ball bearing from falling out; the ball bearing 2054 can only slide out from the side of the cylindrical cavity 2053 closest to the fixing plate 2052. The guide seat 205 is used to hold the contact terminal 202 abutting against the metal strip 103. When the slider 201 is inserted into the groove 102, the ball bearing 2054 falls into the guide groove 105 and rolls along it.

[0027] The conductive terminal 3 includes a fixing block 301 and a contact post 302 retractably mounted on the fixing block 301. The fixing block 301 is made of POM plastic injection molding, and the contact post 302 is made of copper, with a hemispherical front end and a flange at the rear. A return spring is provided between the contact post 302 and the fixing block 301 to maintain contact between the contact post 302 and the second contact terminal 204. The contact post 302 is used for electrical connection with the second contact terminal 204, and can be inserted into the socket 203 and drive the connecting seat 2 to slide along the slide groove 102. The conductive terminal 3 also includes a wire 303 electrically connected to the contact post 302. The fixing block 301 may have mounting ears or clips on both sides for fixing in the fixing groove on the end face of the shelf.

[0028] The conductive strip 1 is installed vertically on the cabinet column or side panel, and the surface of the conductive strip 1 is flush with the surface of the cabinet column or side panel.

[0029] An installation method for a conductive structure based on the combination of contact points and contact wires includes the following steps: Step 1: Pre-process conductive strip 1, connector 2, and conductive terminal 3; Step 2: Install the corresponding number of connectors 2 into the conductive strip 1 according to the number of shelves, so that the slider 201 is placed in the groove 102 and the contact terminal 1 202 abuts against the metal strip 103; Step 3: Vertically install conductive strip 1 into the preset mounting groove of the cabinet column or side panel, and make the surface of conductive strip 1 flush with the surface of the column or side panel; Step 4: Machining a fixing groove and a wire groove on the end face of the shelf, machining a light strip groove on the bottom of the shelf, inserting the conductive terminal 3 into the fixing groove, making one side of the contact post 302 flush with the end face of the shelf, placing the wire 303 into the wire groove, snapping the light strip into the light strip groove and connecting it to the wire 303. Step 5: Slide the connector 2 along the slide groove 102 to the installation position corresponding to the shelf, align the contact post 302 with the insertion hole 203, fix the shelf horizontally, insert the contact post 302 into the insertion hole 203 and drive the connector 2 to be finely adjusted into place, and at the same time, the contact post 302 is electrically connected to the second contact terminal 204.

[0030] When the wardrobe door is opened or the light strip is triggered by other means, current flows from the positive terminal of the power supply through the left metal strip 103, contact terminal 1 202, contact terminal 2 204, contact post 302, and wire 303 to the light strip, and then returns through the right circuit. Because contact terminal 1 202 is an elastic contact, and the spring 2055 inside the guide seat continuously applies pressure, good contact can be maintained even after slight wear on the contact surface over long-term use. The return spring of contact post 302 ensures pressure contact after insertion, while allowing for certain installation tolerances for the shelf. When the shelf height needs to be adjusted, the position of the shelf is adjusted vertically, and the connecting seat 2 slides to the new position via the conductive terminal 3.
