Description

  The present invention relates to a cable holding structure and a cable holding method used for an electronic / electrical device.

  In an electronic / electrical device in which a plurality of components are connected by a cable, the cable may be disconnected by contacting the edge of a surrounding component (for example, a sheet metal) or being sandwiched by a case during assembly. In order to prevent such disconnection of the cable, a cable holder (clamp) that shapes and holds the cable is used.

  As shown in FIG. 8, the conventional cable holder has a holder main body 83 in which a plurality of slits 81 and insertion holes 82 are formed, and a knob portion 84 and a locking portion 85 that are formed to project at both ends. (For example, refer to Patent Document 1).

  This cable holder has flexibility, and the distance between the pair of knob portions 84 can be increased by deforming the pair of locking portions 85 so as to approach each other. Thereby, the slit 81 is opened, and a cable (not shown) can be easily inserted into the insertion hole 82.

  Moreover, the space | interval of a pair of latching | locking part 85 can be expanded by changing a pair of knob part 84 so that it may mutually approach. After positioning a circuit element such as a DIP type IC mounted on the circuit board between the pair of expanded locking portions 85 and then removing the force that deformed the cable holder, the claws of the pair of locking portions 85 Grab the circuit element. As a result, the cable holder fixes the position of the cable passing through the layer through hole 82 with respect to the circuit board.

  Since the conventional cable holder fixes the position of the cable by using the circuit element mounted on the circuit board, there is a problem that the position of the cable cannot be fixed at an arbitrary position.

  Further, when the position of the cable is fixed at a plurality of locations, it is necessary to provide a cable holder at each location, and there is a problem that the number of parts is large and the cost is high.

  Furthermore, since the shape of the conventional cable holder is determined based on the shape of the circuit element to be used, when a plurality of circuit elements having different shapes are used, a cable holder having a shape corresponding to the shape of each circuit element is required. Therefore, there are problems that there are many types of parts and the cost is high.

  Further, since the conventional cable holder is provided perpendicular to the circuit board, there is a problem that the thickness of the entire apparatus is increased.

  Therefore, the present invention provides a cable holding structure that can hold a plurality of cables at an arbitrary position by using a single member and does not increase the thickness of the entire apparatus, and an electronic / electric device including the same. And it aims at providing the cable holding method.

The electronic and electrical devices of the present invention, for achieving the above object, an insulating film, a first slit that is continuous with the edge of the insulating film with consecutive with the first hole, the first hole, 2 A plurality of second holes and a second slit connecting the two second holes, and the holes are formed using the first slit in a state where the insulating film is fixed to the base. to through the cable, further characterized in that said cable is fixed in position inserted through the second hole by using the second slit.

  According to the present invention, a hole and a slit are provided in the film, and the cable is passed through the hole using the slit, thereby holding the cable. Multiple cables can be held at any position. In addition, since the present invention uses a single film, it is inexpensive and there is almost no increase in the thickness of the entire circuit.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 shows an external view of an electronic / electric apparatus according to an embodiment of the present invention. The electronic / electrical device 10 includes an upper cover 11 and a lower cover 12 that are combined with each other.

  FIG. 2 is a plan view of the electronic / electrical device 10 with the upper cover 11 removed. FIG. 3 is a cross-sectional view taken along line AA.

  As shown in FIGS. 2 and 3, the electronic / electric device 10 includes a sheet metal 21, first to third components (for example, circuit boards) 22 to 24, first and second cables 25 and 26, and And a protective film (insulating film) 27.

  The sheet metal 21 and the first component 22 are respectively fixed to different positions of the lower cover 12. The second and third parts 23 and 24 are fixed to the sheet metal 21.

  The first cable 25 electrically connects the first component 22 and the second component 23. The second cable 26 electrically connects the second component 23 and the third component 24.

  The protective film 27 is provided between the sheet metal 21 and the second component 23, and is attached to the sheet metal 21, for example. The protective film 27 has holes and slits as will be described later. The protective film 27 uses these holes and slits to shape the first and second cables 25 and 26 into the first and second cables and fix the positions.

  FIG. 4 shows an example of holes and slits formed in the protective film 27. The hole 41 in FIG. 4 is formed near the edge of the protective film 27, and the slit 42 is formed to be continuous with the hole 41 and the edge of the protective film 27.

  FIG. 5 shows another example of holes and slits formed in the protective film 27. The holes 51 and 52 in FIG. 5 are formed near the edge of the protective film 27, and the slit 53 is formed so as to connect the holes 51 and 52.

  The first cable 25 that electrically connects the first component 22 and the second component 23 includes a hole 41 and a slit 42 shown in FIG. 4, and holes 51, 52 and a slit 53 shown in FIG. Using this combination, it is shaped, held and fixed in position as shown in FIG. Due to the presence of the slits 42 and 53, the first cable 25 can be easily passed through the holes 41, 51 and 52 even when the protective film 27 is attached to the lower case 12.

  The second cable 26 that electrically connects the second component 23 and the third component 24 is shaped and held as shown in FIG. 7 using the holes 41 and slits 42 shown in FIG. The position is fixed. Again, the presence of the slit 42 allows the second cable 25 to be easily passed through the hole 41 even when the protective film 27 is attached to the lower case 12.

  As described above, the first and second cables 25 and 26 are fixed in position by the protective film 27, and can be prevented from being disconnected due to contact with other components or pinching during case assembly.

  In each example shown in FIGS. 6 and 7, the inner diameters of the holes 41, 51, 52 are made larger than the outer diameters of the first and second cables 25, 26, but these are made substantially equal. Thus, the first and second cables 25 and 26 can be held more firmly.

  As described above, according to the present embodiment, a plurality of cables can be shaped and fixed using a single protective film, and the number of parts and the cost can be reduced. Moreover, the cable drawn out from each component can be fixed at an arbitrary position around the component. Furthermore, the thickness of the entire apparatus is hardly increased.
