Lighting wiring installation structure

Abstract

The invention provides an automotive lamp wire mounting structure. The automotive lamp wire mounting structure is provided with a lamp body outer cover (11), a lamp body shell (12), a lamp body substrate (31), an electric wire (41) and an electric wire fixing component (13), wherein an electric wire mounting terminal (32) is arranged on the lamp body substrate; a guiding-out hole (15) which extends in the length direction of the lamp body outer cover and has the specified length is formed in the lamp body shell; one end of the electric wire is connected with the electric wire mounting terminal in space surrounded by the lamp body outer cover and the lamp body shell; the other end of the electric wire penetrates out of the lamp body shell via the guiding-out hole and then is connected with an external power supply; the part, at the position of the guiding-out hole, of the electric wire is bent in a U shape; and the electric wire fixing component is assembled on the surface, which is provided with the guiding-out hole, of the lamp body shell, and is used for fixing the electric wire penetrating through the guiding-out hole on the lamp body shell. Thus, the novel automotive lamp wire mounting structure which can be simple in structure and low in cost, and can efficiently absorb length tolerance of the wire is provided.

Description

technical field [0001] The invention relates to a vehicle light wiring installation structure, in particular to a wiring installation structure suitable for high-position brake lights and other vehicle light wiring with long wiring. Background technique [0002] Generally, a large number of wire harnesses are assembled in a vehicle to drive various devices such as lights of the vehicle. In order to prevent these wire harnesses from vibrating during the running of the vehicle, the wire harnesses are fixedly arranged in a small space of the vehicle. In addition, for To absorb manufacturing tolerances and assembly tolerances of wire harnesses, a tolerance absorbing structure with wire harnesses has been proposed (for example, Patent Document 1). [0003] In the tolerance absorbing structure of the wire harness described in Patent Document 1, as shown in FIGS. 5A and 5B , a shield 29 and an inner retainer 31 are included. A supporting piece 41 extending in a direction perpendic...

Problems solved by technology

[0005] However, the tolerance absorption length of this tolerance absorption structure is limited by the movable range of the inner retainer 31 and the length of the long hole, and the tolerance can only be absorbed in one direction, the axial direction, and the tolerance absorption range is limited.

If the tolerance absorbing structure of Patent Document 1 is applied to components with long wires such as high-mounted stop lamps, the wires have large tolerances, and there are cases where the tolerances of the wires cannot be completely absorbed. The phenomenon that the wire is bent and twisted

On the other hand, if the moving range of the inner holder and the length of the long hole are set to be larger in order to fully absorb the length tolerance of the electric wire, there is a problem that more space is occupied and the degree of freedom of space is reduced.

In addition, in Patent Document 1, the tolerance is absorbed by two components, the inner retainer and the long hole, the number of components is large, the structure is complicated, and the assembly process for absorbing the tolerance of the wire harness is complicated, and it cannot be realized at low cost.
