Technical Field
[0001] The utility model relates to a lamp, more specifically to a mainboard mounting box of a narrow signal lamp. Background Art
[0002] Existing narrow signal lights are long strips and can be used on vehicle pedals to provide both lighting and indication. Typically, a motherboard (circuit board) is installed within the lamp housing of a narrow signal light. The motherboard is installed in a separate mounting box and sealed with glue. However, the structural design of the motherboard mounting box within existing narrow signal lights is irrational. The motherboard mounting box is designed to accommodate the width of the narrow signal light. The motherboard is arranged horizontally, i.e., along the width of the narrow signal light. The opening of the motherboard mounting box corresponds to the depth of the narrow signal light. Therefore, the motherboard box has a larger opening, and the motherboard's wiring terminals are operated in the depth of the narrow signal light, providing more space for wiring operations. However, this design has the following drawbacks:
[0003] 1. The opening of the motherboard box is large, which makes the subsequent glue filling process inconvenient and increases the amount of glue required, increasing the cost;
[0004] 2. It is impossible to effectively distinguish and locate the connecting wires, which causes inconvenience in assembly. At the same time, the wires are easily pulled, resulting in the risk of loosening of the electrical connection points. Summary of the Invention
[0005] The purpose of the invention of the utility model is to overcome the defects of the prior art, and to provide a narrow signal light mainboard mounting box that is convenient for sealing and filling with glue, and can reduce the amount of sealant filling and reduce costs.
[0006] To achieve the above objectives, the present invention provides the following technical solutions:
[0007] A mainboard mounting box for a narrow signal light comprises a box body, the box body comprising a bottom and wall panels surrounding the bottom, the box body having a mainboard positioning cavity with an opening at one end, one end of the box body in the height direction being the opening and the other end being the bottom opposite to the opening, characterized in that: the mainboard positioning cavity is a narrow groove for vertical insertion of the mainboard, a first positioning support wall is provided on one side in the width direction of the box body, a positioning support protrusion is raised on the other side wall in the width direction of the box body, and a line spacing cavity is formed between the positioning support end of the positioning support protrusion and the box body wall.

[0009] Preferably, the wire arranging plate comprises a first wire arranging plate body and a second wire arranging plate body, the first wire arranging plate body and the second wire arranging plate body are arranged at intervals along the length direction of the box body, the wire arranging hole comprises a plurality of separated wire arranging holes distributed along the length direction of the first wire arranging plate body, and the wire arranging hole comprises a laterally opened wire arranging hole arranged on the second wire arranging plate body, and the lateral opening of the wire arranging hole corresponds to the interval between the first wire arranging plate body and the second wire arranging plate body.
[0010] Preferably, the wire arranging plate is a positioning support protrusion with a support end face, and the positioning support protrusion further comprises a lower protrusion corresponding to the bottom position of the box body.
[0011] Preferably, the top of the wire arranging plate is recessed with a sink, the sink penetrates from the edge wall of the opening end of the box body to the main plate positioning cavity of the box body, and an upper protruding edge flush with the top wall of the opening end of the box body is formed at the edge of the sink.

[0015] By adopting the above technical scheme, the main plate is vertically inserted into the main plate mounting box, and the main plate positioning cavity of the main plate mounting box is a narrow groove. On the one hand, the opening of the main plate positioning cavity is narrower, so that the glue sealing is easier, and the amount of glue required is reduced, thereby reducing the cost. On the other hand, the wire passing interval cavity is formed outside the main plate positioning cavity of the box body, and the wire passing interval cavity provides the positioning and passing of the wire.

[0023] Referring to the drawings Figures 1-6The utility model discloses a mainboard assembly of narrow type signal light, including mainboard 2 and mainboard installation box 1, mainboard installation box 1 includes box body 11, and box body 11 includes a bottom 111 and the wallboard of surrounding in the four around of bottom 111, and box body 11 has the mainboard positioning cavity 112 of one end opening 110, and the mainboard 2 is installed in the mainboard positioning cavity 112, and the one end of box body 11 height direction is the opening 110 and the other end is the bottom 111 opposite to opening 110, the mainboard positioning cavity 112 is the narrow slot for the vertical insertion of mainboard 2, and the mainboard positioning cavity is more flattened design compared to prior art, and the width of opening 110 and the thickness of mainboard 2 are matched, thereby reducing the opening width size, so that the glue sealing is more simple and convenient, and the glue required for the waterproof sealing treatment of opening is less, and the glue amount is reduced, and the cost is reduced, and the mainboard 2 is vertically inserted into the narrow slot, so as to make the width of box body 11 and the lamp shell of narrow type signal light adapt, ensure that mainboard installation box is installed reliably, and box body 11 width direction one side has first positioning support wall 113, and positioning support protruding 12 is protruded on the other side wall of box body 11 width direction, and the positioning support end 121 of positioning support protruding 12 and the wall between box body 11 interval form wire spacing cavity 10. Due to the flattened design of mainboard positioning cavity, wire spacing cavity can be formed outside the mainboard positioning cavity of box body, and the wire connected to the mainboard is positioned and passed through. The terminal provides the connection of the wire to facilitate the assembly operation, so as to make the wire connection operation convenient and reliable, and the terminal support step 1121 for supporting the terminal 21 on the mainboard 2 is protruded on the bottom of the mainboard positioning cavity 112, so that when the mainboard is inserted into the mainboard positioning cavity, the terminal is supported on the terminal support step 1121, and the support of the terminal insertion operation is provided to protect the terminal on the mainboard, and the terminal support step 1121 is located on the side of the mainboard positioning cavity 112 transversely close to the wire spacing cavity 10, and the recess 1111 is arranged at the terminal support step 1121 of the outer wall of the bottom of the box body 11, which can reduce the material of the box body 11 and reduce the weight of the box body 11.
[0024] The wire spacing cavity 10 is formed between the positioning support end 121 of the positioning support protruding 12 and the wall of the box body 11, and the wire spacing cavity 10 is arranged on the side of the mainboard positioning cavity 112 transversely close to the wire spacing cavity 10, and the recess 1111 is arranged at the terminal support step 1121 of the outer wall of the bottom of the box body 11, which can reduce the material of the box body 11 and reduce the weight of the box body 11.
[0025] Further, the wire arrangement plate is more reasonably optimized according to the wire distribution on the main plate, so as to facilitate the arrangement of the wires, and specifically, the wire arrangement plate 13 comprises a first wire arrangement plate body 13-1 and a second wire arrangement plate body 13-2, the first wire arrangement plate body 13-1 and the second wire arrangement plate body 13-2 are arranged at intervals along the length direction of the box body 11, the wire arrangement holes comprise a plurality of separated wire arrangement holes 131-1 distributed along the length direction of the first wire arrangement plate body 13-1, and wire clamping holes 131-2 provided on the second wire arrangement plate body 13-2 and laterally opened 131-21, the lateral opening 131-21 of the wire clamping hole 131-2 corresponds to the interval between the first wire arrangement plate body 131-1 and the second wire arrangement plate body 131-2. The wires connected to the plurality of terminal clamps on the main plate can pass through the separated wire arrangement holes respectively, and be positioned and arranged in zones (as shown in Figure 1 The electronic device at one end of the main plate has more wires, and the wires can be installed and positioned by being laterally clamped through the wire clamping holes Figure 1 The wires in this part are not shown), which is simple and convenient, and makes full use of the interval between the first wire arrangement plate body and the second wire arrangement plate body, and the structure is compact.
[0026] In order to be compact, the wire arrangement plate 13-1 is usually used as a positioning support protrusion 12 with a support end face at the same time, so that a support is provided at the opening end position of the box body, and therefore the positioning support protrusion 12 further comprises a lower protrusion 12-1 corresponding to the bottom position of the box body. The lower protrusion can be a protruding column arranged at the two end positions in the length direction of the box body.
[0027] As an embodiment of the utility model, a sink 132 is recessed at the top of the wire arrangement plate 13, the sink 132 penetrates from the edge wall of the opening end of the box body 11 to the main plate positioning cavity 112 of the box body 11, and an upper protruding surrounding edge 133 flush with the top wall of the opening end of the box body 11 is formed at the edge of the sink 132. In this way, the wires on the main plate can more conveniently pass through the wire arrangement holes by bypassing the edge, the upper protruding surrounding edge ensures the reliable positioning of the edge of the main plate mounting box, the upper protruding surrounding edge can protect the wires, avoid the wires being crushed when the main plate mounting box is installed into the signal lamp, and also make the assembly of the main plate more convenient.
[0028] As an embodiment of the utility model, a screw hole column 114 is arranged at the middle position in the main plate positioning cavity 112, and a main plate limiting screw 14 is screwed on the screw hole column 114. The main plate limiting screw is pressed on the main plate, so as to limit the main plate in the main plate positioning cavity, make the fixation of the main plate more reliable, avoid the main plate being forced out after the wires are bent and bypassed, and also provide convenience for the subsequent glue filling treatment.
[0029] Since the traditional mainboard mounting box is made of plastic, although the plastic injection molding is relatively simple and low in cost, it also brings reliability problems; since the mainboard is assembled into the mainboard mounting box and then treated with glue pouring, and due to the limited space of the narrow signal lamp, it is difficult to dissipate heat, and the traditional mainboard mounting box leads to insufficient heat dissipation performance and insufficient corrosion resistance (and the narrow signal lamp will be applied to the vehicle footboard, the environment is relatively harsh), therefore, the box body 11 is made of a metal heat conductor. In this way, the box body and the profile lamp shell of the narrow signal lamp are in contact, metal and metal are in contact, better heat conduction of the box body is achieved, and the heat dissipation performance is improved; in addition, the metal has better corrosion resistance.
[0030] The above-mentioned mainboard assembly is applied to a narrow signal lamp, and the narrow signal lamp usually adopts a profile lamp shell, the profile lamp shell is provided with a lampshade, and the mainboard mounting box 1 of the mainboard assembly is positioned and mounted in the profile lamp shell. After the mainboard mounting box 1 is made of metal, the mainboard mounting box and the metal profile lamp shell are in contact, good heat conduction can be achieved, and the heat dissipation performance of the mainboard assembly is improved.
[0031] The mainboard is vertically inserted into the mainboard mounting box, and the mainboard positioning cavity of the mainboard mounting box is a narrow slot, so on the one hand, the opening of the mainboard positioning cavity is narrower, making it easier to seal with glue pouring, and the amount of glue required is reduced, reducing costs; on the other hand, more importantly, the formation of the wire passing interval cavity provides further design space for the wire passing and wire arrangement structure, that is, the wire arrangement plate can be arranged using the space of the wire passing interval cavity, multiple wire arrangement holes can be arranged on the mainboard according to needs, different wires are separated and arranged, and the wire arrangement effect is further improved; and after the wire connected to the mainboard passes through the wire passing opening, it passes through the wire arrangement hole of the wire arrangement plate, the wire passes through the wire arrangement hole and passes through the wire passing interval cavity, when the wire is pulled, the wire is first restrained by the wire arrangement plate, reducing or avoiding the pull being transmitted to the connection position of the wire and the mainboard, thereby ensuring the reliability of the product.
