Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric wire holding device for positioning and holding an electric wire such as a flat cable connected to a head of office equipment, for example, a printer.

[0002]

[Prior Art]

 As shown in FIG. 4, a conventional wire holding device of this type has an electric wire arranging portion 4 formed between ridges 2 and 3 protruding from a substrate 1 and a flat wire arranging in the electric wire arranging portion 4. A structure has been adopted in which the flat cable 5 is held by engaging both edges of the pressing piece 7 with the engaging groove 6 formed on the opposite surfaces of the ridges 2 and 3 of the cable 5.

[0003]

[Problems to be solved by the device]

 In the electric wire holding device having the above-described conventional structure, the flat cable 5 can be positioned and held, but a guide boss is required to change the wiring direction of the flat cable 5, and a large space is required for wiring the flat cable. There was a problem to do.

In addition, when the flat cable is held for positioning, holding and guiding, there is a problem that the flat cable is crushed when an external force is applied from above.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an electric wire holding device capable of positioning and holding electric wires without requiring a large wiring space for the electric wires.

[0006]

[Means for Solving the Problems]

 An electric wire holding device of the present invention is provided so as to project from a first member, a second member coupled to the first member, and at least one of the first member and the second member. It has a boss that joins both members and guides the electric wire, and a recess for positioning and holding the electric wire is formed in a part of this boss.

[0007]

[Action]

 In the wire holding device of the present invention, the wire can be positioned and held and guided by fitting the wire midway into a recess formed in a part of a boss that connects the first member and the second member.

[0008]

【Example】

 The configuration of an embodiment of the wire holding device of the present invention will be described with reference to FIGS.

Reference numeral 10 is a first member, for example, a carrier of a printer, to which a print head 11 is attached. Also, the carrier 10 is provided with boss receiving projections 12 and 13, and fitting holes 14 are formed on the upper surfaces of the boss receiving projections 12 and 13, respectively.

Reference numeral 15 is a second member, for example, a ribbon feed block, and bosses 16 and 17 for connecting the ribbon feed block 15 to the carrier 10 are provided on the lower surface of the ribbon feed block 15 in a protruding manner. On the lower surfaces of the bosses 16 and 17, there are provided projections 18 which are fitted and fixed in the fitting holes 14 formed in the boss receiving projections 12 and 13. A ribbon cassette 19 is detachably attached to the ribbon feeding block 15 so that the ribbon of the ribbon cassette 19 can be wound up according to a printing operation.

Reference numeral 20 denotes an electric wire such as a flat cable. One end of the electric wire 20 is connected to the print head 11, and the other end is connected to a fixed machine body side connection portion (not shown) on which the carrier 10 is movably provided. It is connected.

A recess 21 is formed in the lower portion of the one boss 16 so that the electric wire 20 can be fitted and held in the recess 21.

Next, the operation of this embodiment will be described.

When the projection 18 of the boss 16 is fitted into the fitting hole 14 of the boss receiving projection 12, a bent portion 22 that changes the direction of the electric wire 20 is held between the recess 21 and the boss receiving projection 12. The electric wire 20 is fitted between the recess 21 and the upper surface of the boss receiving projection 12 by the elasticity of the insulating coating of the electric wire 20, and the electric wire 20 is positioned and held and guided.

Even if an external force acts on the ribbon feeding block 15, no pressing force acts on the electric wire 20, and the electric wire 20 is not crushed.

Although the electric wire 20 has been described as a flat cable in the above embodiments, the electric wire 20 is not limited to a flat cable and can be applied to holding various electric wires, and the electric wire 20 can be held without being bent.

Further, the invention is not limited to the printer, but can be applied to the electric wire holding of various devices.

[0018]

[Effect of the device]

 According to the present invention, the electric wire can be positioned and held and guided by fitting the electric wire midway into the recess formed in a part of the boss that connects the first member and the second member. Not only can the space be reduced, the positioning and holding of the wire can be done with a single boss, and the wire will not be crushed even if pressure is applied to the first member or the second member. With a simple structure with few wires, the wire can be securely held.
