Description

[Detailed Description of the Invention] The present invention relates to a structure that prevents a cable drawn out from the casing of an electronic device, such as an electron microscope, a television camera, an electronic counter, a programmable controller, a photoelectric device, or a proximity switch, from easily coming out of the electronic device. .

Conventionally, in the structure for fixing a cable to the casing of a small electronic device such as a photoelectric switch, a caulking part 6 is provided on the inner surface of a cable pull-out hole 3 provided in a case 1 as shown in FIG. After storing the elastic member 5 through which the cable has penetrated and the cable fixing ring 4 fixed to the cable into the pull-out hole 3, the caulking portions 6, 6, 6 are plastically deformed in the inner diameter direction by a caulking means to remove the cable fixing ring 4. It is practiced to cover the periphery of the hole and fix it in the pull-out hole 3 (see Japanese Utility Model Application Publication No. 168938/1983).

However, forming a caulked portion on the inner surface of the cable storage hole of a small case makes molding or turning difficult, and once the caulked portion is plastically deformed, it must be returned to its original state to remove the cable. It is almost impossible to re-fasten it, and furthermore, it has disadvantages such as inserting a jig into a small case and caulking it in a narrow space, which makes assembly work difficult. .

The technical problem of the present invention is that by interposing a tie wrap on the cable inserted into the support section of the electronic device, the cable can be securely held in the cable pull-out section (support section) of the electronic device, and the cable can be fixed easily. The cable can be easily removed from the support part, and the support part can be easily turned with a machine tool to form the cable insertion hole and the U-shaped groove for storing the tie wrap after molding. Therefore, it is easy to form the cable fixing part.

The structure of the present invention, that is, the technical means for solving the above technical problem is as follows.

In a cable fixing structure for fixing one end of a cable to an arbitrary location of an electronic device, etc., a cable insertion hole that substantially matches the outer diameter of the cable is formed in a support portion that holds the cable, and a U that surrounds the cable insertion hole is formed. Insert one end of the tie wrap into the U-shaped groove of the support part so as to wind the cable to be inserted into the cable insertion hole, and insert the other end into the stopper hole of the locking part of the tie wrap. A cable fixing structure for electronic equipment, etc., characterized in that the cable is fixed to a support portion by passing one end of the tie wrap through.

The above technical means has the following effects.

Since the support part only needs to have a cable insertion hole and a U-shaped groove around the insertion hole that is approximately equal in thickness to the tie wrap width, the support part only needs to have a small wall thickness, and the electronic components housed in the casing can be easily accommodated. does not interfere with the incorporation of

Since the portion of the cable to be fixed is housed within the support section, it is sufficient that there is a gap between the inner surface of the support section and the outer surface of the electronic component placed inside the casing, allowing the cable lead wire to pass through. This is convenient for downsizing.

Furthermore, unnecessary portions of the tie wrap that secures the cable within the support section are cut off and stored in the storage groove formed at the open end of the support section, so that they do not interfere with the installation of electronic components.

In addition, the support part is integrally molded with the casing from die-cast alloy, plastic material, or synthetic rubber material, and the cable insertion hole and the U-shaped groove can be easily turned by machining, and the cable insertion hole and the U-shaped groove can be easily turned by machining. It is also possible to form a U-shaped groove.

A preferred example of the present invention will be explained below based on the drawings.

Figure 2 shows the microscope from the TV camera to the case (2).
FIG.

A support portion 10 integrally formed with a mound base 11 to which a business controller and an electronic circuit board (not shown) are attached is molded from a light alloy such as a die-cast alloy.

A cable insertion hole 12 is bored in the support portion 10 .

A U-shaped groove 13 is formed approximately perpendicularly to the cable insertion hole 12 from the upper surface to the lower surface of the support portion 10, whereby the tie wrap 19 can be inserted and guided, and an open end 15 is formed. .

Reference numeral 16 designates a storage groove formed at the open end 15 for storing a locking portion of the tie wrap 19.

18 is a cable, 19 is a commercially available tie wrap (wire bundle band), 20 is a locking part of the tie wrap 19, 2
1 is a stopper hole of the locking part 20, 22 is a stopper protruding into the locking part 20, 23 is a protrusion formed on the belt 24 of the tie wrap 19, 25
is a case, 26 is a vidicon (image pickup tube), 27 is a vidicon coil, and 8 is a bracket.

Its action is as follows: First, the cable 18 is inserted into the cable insertion hole 12 of the support part 10, and then the tie wrap 19 (see FIG. 6) is pressed and inserted through the U-shaped groove 13 of the open end 15 of the support part 10. The tie wrap 19 is guided along the inner circumference of the U-shaped groove 13, goes around the outer circumference of the cable 18, passes through the storage U groove 16 of the locking part, and projects from the open end 15.

The protruding portion of the tie wrap 19, that is, the belt 24, is inserted into the stopper hole 20, and the protrusion 2 formed on the belt 24 of the tie wrap 19 is inserted.
3 to the stopper 22, and then connect the cable 18
Perform tightening.

After that, cut off the excess of the belt 24,
The tip 17 and the locking piece 20 are connected to a groove 1 for storing the locking part formed in the open end 15 of the support part 10.
6, and the cable fixing of the present invention is completed.

In addition, in the above embodiment of the present invention, the support part 10
has described an example in which it is formed integrally with the mount base 11, but as shown in FIG.
Of course, it is also possible to integrate the separate parts of the support part 9 and the support part 10 by an appropriate fixing means such as fixing means using screws 30 or fixing means not using screws, such as adhesion. It is also possible to form the support portion 10 at any location on the casing.

As mentioned above, the cable fixing structure of the present invention has an extremely simple structure in which a tie wrap is press-inserted into a U-shaped groove formed in the support part, and the tie wrap belt portion is inserted into the stopper hole of the locking piece. can be easily prevented from falling off.
