Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shaft cover structure of a slide type switch used as a function switch of electronic equipment.

[0002]

[Prior Art]

 FIG. 2 is a cross-sectional view showing a shaft cover structure of a conventional slide switch. 1 is a substrate, 2 is a slide switch soldered to the substrate 1, 3 is a thin plate cover, and an engaging hole is formed in the center. A pair of slits 3a is provided on both sides, and the switch shaft 2a is press-fitted into the soft. Reference numeral 4 is an escutcheon having a window 4a. FIG. 3 is also a sectional view showing a conventional shaft cover structure. Reference numeral 13 is a cap-shaped cover, and the shaft's 2a is fitted with a deep groove 13a of the cover. 4 is an escutcheon that surrounds the whole.

Next, the operation will be described. In FIG. 2, a thin plate cover 3 is attached to a shaft 2a protruding from the center of a slide switch 2 fixed to a substrate 1 by soldering, and the thin plate cover 3 is attached to the shaft 2a. A pair of slits 3a are provided to the left and right of the engagement hole, which is slightly smaller than the shaft 2a, so that the shaft 2a can be held when the shaft 2a moves in the direction of arrow A. The shaft 2a projects from a window 4a of the escutcheon 4 which surrounds the whole with a gap g between the shaft 2a and the cover 3. Next, in FIG. 3, the cap-shaped cover 13 is fitted and attached to the shaft 2a of the slide switch 2 fixed in the same manner as described above. That is, a deep groove 13a is provided on the inner side of the protrusion protruding from the central portion of the cap-shaped cover 13 so that the shaft 2a can be fitted and fitted properly. The shaft 2a is held through the cap-shaped cover 13 even when the shaft 2a is moved in the direction of arrow A in FIG. It is done like this.

[0004]

[Problems to be solved by the device]

 Since the conventional shaft cover structure is configured as described above, it may be displaced toward the switch shaft direction due to contact when attaching or detaching the escutcheon 4 during repair service or line work, or it may fall off if strongly touched. There was such a problem.

The present invention has been made in order to solve the above-mentioned problems, and an axis which is not likely to be displaced or dropped in the switch axial direction due to contact with an escutcheon or a human hand at the time of repair service and assembly work. The purpose is to obtain a cover structure.

[0006]

[Means for Solving the Problems]

 In the shaft cover structure according to the present invention, a plurality of pairs of projection pieces are provided on the side edge of the slide switch shaft cover, and a locking claw is provided at the tip of the slide switch so as to engage the cover with the shaft and face the projection pieces. The board is provided with an elongated hole into which the locking claw of the cover is engaged.

[0007]

[Action]

 The projection piece provided on the side edge of the cover in this invention has elasticity, and in a state of being engaged and locked with the locking elongated hole provided on the board, the protruding piece of the cover is engaged with the locking elongated hole of the board. The locking claw is always held with a reaction force.

[0008]

【Example】

 Example 1. An embodiment of this invention will be described below with reference to FIG. In FIG. 1, 1 is a substrate, 2 is a slide type switch fixed to this substrate by soldering, and long holes 1a and 1b are provided in the upper and lower substrates of this switch. 2a is a shaft of a slide type switch. Reference numeral 23 denotes a cover to be mounted on the shaft 2a, and the shaft 2a is mounted by being engaged in a deep groove 23b provided inside the protrusion 23a at the center of the cover. Reference numerals 23c and 23d are a plurality of pairs of protrusions provided above and below the side edge of the cover, and at their tips are formed locking claws 23e for engaging and locking the elongated holes 1a and 1b of the substrate 1, respectively. There is. Reference numeral 4 is an escutcheon, which wraps the entire above-mentioned component and a protrusion 23a at the center of the cover projects from the window 4a.

Next, the operation will be described. As in the prior art, the shaft 2a of the slide switch 2 fixed to the substrate 1 by soldering is engaged with the deep groove 23b of the cover 23, and the projection pieces 23c and 23d provided on the side edges of the cover 23 are The locking claw 23e at the tip is engaged with the locking holes 1a and 1b provided in the substrate 1 while maintaining elasticity, and the projection pieces 23c and 23d of the cover 23 always apply a reaction force to the locking holes. Kept and held. The reaction force of the protruding piece of the cover 23 ensures that the shaft 2a is reliably held even when the shaft 2a moves in the direction of the arrow in FIG.

[0010]

[Effect of the device]

 As described above, according to the present invention, the elastic protruding piece is provided on the side edge of the cover that engages with the shaft, and the locking claw is provided at the tip of the projecting piece. Since it is configured so as to be locked, it can be mounted on the slide switch at the same time as it is mounted on the board very easily, and it is possible to prevent axial displacement or dropout due to human hand or escutcheon contact.
