Description

  The present invention relates to a conductor holding structure for holding a conductor, a display device including the conductor holding structure, and a television receiver.

  In recent years, in order to realize miniaturization and thinning of electric appliances, a space through which wiring in a housing is passed has been limited. In a liquid crystal display device, a space through which a harness (wiring) is passed is limited as the frame is narrowed, and it is desired that the harness is securely held in the given space. When the range in which the harness can freely move is large, a production defect such as disconnection caused by the harness being sandwiched by the housing during assembly occurs. In addition, there may be a safety problem such as a short circuit failure of the electronic component due to contact between the harness and the electronic component, or a malfunction due to power supply noise superimposed on the control signal.

  On the other hand, although it is certain to use a wire holder to hold the harness, it leads to an increase in the number of parts and assembly man-hours. On the other hand, hooks and ribs are alternately formed integrally in a cabinet, and a harness is fixed by the hooks and ribs (for example, Patent Document 1).

  Then, the rear cabinet 20 is covered from the rear side of the backlight chassis 18, and a screw is passed through a through hole provided in the rear cabinet 20 and a through hole of the middle cabinet 19 provided at a position corresponding to the through hole. The screw is screwed into a female screw of the backlight chassis 18 provided at a position corresponding to the through hole. Thereby, the rear cabinet 20 is fixed to the backlight chassis 18.

  Next, the middle cabinet 19 will be further described. FIG. 4 is a front perspective view showing the middle cabinet 19. FIG. 5 is a rear perspective view showing the middle cabinet 19. The middle cabinet 19 has a rectangular frame shape. Each of the middle cabinets 19 includes an upper part 191, a right part 192, and a left part 193 having a substantially L-shaped cross section. The lower side of the middle cabinet 19 includes a plate-like portion 194 that is long in the left-right direction and extends upward from the lower end, and a lower plate portion 195 that continues to the plate-like portion 194 and protrudes forward. Further, the middle cabinet 19 includes a lower exterior portion 196 that extends obliquely downward from the front end of the lower plate portion 195. The plate-like portion 194 and the lower plate portion 195 of the middle cabinet 19 form a member having a substantially L-shaped cross section. On one surface of each of the upper part 191, the right part 192, and the left part 193 of the middle cabinet 19, a screw hole 19a through which a screw passes is formed at a predetermined location. Similarly, the plate-like portion 194 has screw holes 19a formed at predetermined positions.

  FIG. 6 is a partially enlarged perspective view of the middle cabinet 19. FIG. 6 roughly shows the inside of the rectangular frame A shown in FIG. The middle cabinet 19 is formed with a hook (regulating claw portion) 19b and a pin (regulating convex portion) 19c as a structure (holding structure) for holding a harness (conductor). In the example shown in FIG. 6, the base of the hook 19b is integrated with the cylindrical rib 19d. The base of the hook 19b is connected to the side surface of the cylindrical rib 19d, and the connecting portion is slightly rearward from the middle in the front-rear direction. The hook 19b includes a rectangular plate-like main body portion 19b1 extending upward from the cylindrical rib 19d, and a reverse-tapered projection portion 19b2 from the tip of the main body portion 19b1 to the base (from top to bottom). A portion of the plate-like portion 194 facing the hook 19b is provided with a notch. The pin 19c has a cylindrical shape and protrudes rearward from the plate-like portion 194. The pin 19c is positioned below the protrusion 19b2 and in the root direction of the hook 19b. The distance between the pin 19c and the cylindrical rib 19d is a value through which the wired harness passes.

  FIG. 7 is an explanatory view showing a state in which the harness h is fixed by the hook 19b and the pin 19c. 7B is a cross-sectional view taken along line VII-VII in FIG. 7A. As shown in FIG. 7, the harness h is a wiring that crosses the hook 19b in the left-right direction and goes upward from the left of the pin 19c. Since the harness h hits the cylindrical rib 19d at the base of the hook 19b, the harness h is restricted from moving downward. The harness h is restricted from moving upward by the protrusion 19b2 and the pin 19c at the tip of the hook 19b. The movement of the harness h in the front-rear direction is restricted by the hook 19b and the plate-like portion 194.

  Embodiment 1 has the following effects. Since the harness h is held by the hook 19b and the pin 19c, even if a slight force is applied to the harness after wiring, it is possible to prevent the harness h from being detached from the hook 19b. In particular, as shown in FIG. 7, when the harness h is bent and wired in the opening direction (upward direction) of the hook 19b in the vicinity of the hook 19b, the regulation of the harness h by the pin 19c is particularly effective.

(Embodiment 2)
The second embodiment relates to a form in which the hook 19b is formed in the plate-like portion 194. FIG. 8 is a perspective view showing the hook 19b and the pin 19c in the second embodiment. The hook 19 b is formed so as to be integrated with the plate-like portion 194. Since other configurations are the same as those in the first embodiment, the description thereof is omitted.

  Similarly to the first embodiment, the second embodiment can prevent the harness h from coming off the hook 19b even if a slight force is applied after the harness h is wired.

(Embodiment 3)
The third embodiment relates to a form in which the pin 19c is reversely tapered. FIG. 9 is a perspective view showing the hook 19b and the pin 19c of the third embodiment. In the third embodiment, the pin 19c is reversely tapered. That is, the root diameter r1 of the pin 19c is shorter than the tip diameter r2. Since other configurations are the same as those in the first embodiment, the description thereof is omitted.

  In the third embodiment, since the pin 19c has an inverse taper, even when a force is applied to the harness h, the harness h moves in the longitudinal direction of the pin 19c as compared with the case where the pin 19c has a cylindrical shape. There exists an effect of suppressing coming off from 19c. Therefore, it is possible to more reliably prevent the harness h from coming off the hook 19b.

(Embodiment 4)
The fourth embodiment relates to other shapes of the pin 19c. FIG. 10 is a perspective view showing the hook 19b and the pin 19c in the fourth embodiment. In the fourth embodiment, the pin 19c has a polygonal column shape. In the example shown in FIG. Since other configurations are the same as those in the first embodiment, the description thereof is omitted.

  In the fourth embodiment, since the pin 19c has a polygonal column shape, the harness h is less likely to slip with respect to the pin 19c even when a force in the extending direction is applied to the harness h. Thereby, it is possible to more reliably prevent the harness h from being detached from the hook 19b.

(Embodiment 5)
The fifth embodiment relates to a pin 19c having a different shape. FIG. 11 is a perspective view showing the hook 19b and the convex portion 19e in the fifth embodiment. The convex portion 19e has the same function as the pin 19c shown in the above-described embodiment. As shown in FIG. 11, the convex portion 19 e has a horizontal triangular prism shape, and a portion corresponding to one side surface of the triangular prism is integrated with the plate-shaped portion 194. The upper surface of the convex portion 19e is an inclined surface 19e1 having a reverse taper shape from the front side (tip) to the rear side (root). The lower surface 19e2 of the convex portion 19e is perpendicular to the plate-like portion 194. Since other configurations are the same as those in the first embodiment, the description thereof is omitted.

  Since the convex portion 19e has the slope 19e1 described above, the harness is easily hooked on the convex portion 19e. The harness wired from the right side (left side of the drawing) is hooked on the hook 19b. The harness located on the right side (left side of the page) of the hook 19b is slid down from the top of the slope 19e1. The harness removed from the tip of the convex portion 19e is hooked on the base of the convex portion 19e along the lower surface 19e2 of the convex portion 19e. Wire the hooked harness upward.

  In the fifth embodiment, since the convex portion 19e has a horizontal triangular prism shape, the harness can be easily hooked on the convex portion 19e.

  In the above-described embodiment, the television receiver 1 is provided with the holding structure. However, if it is necessary to wire and hold a wire such as a harness in the cabinet, the television receiver 1 may be installed in an electrical device other than the television receiver.
