Description

[Detailed description of the invention] [Industrial application field] This invention is installed in computers, communication equipment, vending machines, office equipment, etc. to realize address settings, amount corrections, date settings, etc. The present invention relates to a dip switch, and particularly to a dip switch mounted on a printed circuit board and used for switching circuit patterns.

[Conventional technology]

Conventionally, a deep switch has been configured such that electrical connections can be switched by sliding a knob 2 from outside the switch case 1, as shown in FIG. 7 for an example. .
This is convenient, for example, for switching the circuit pattern connected to the lead contact 3. In the deep switch shown in FIG.
are arranged in the longitudinal direction. Each slider 4 has a knob 2 on its upper surface for sliding operation and identification of the set position. Each slider 4
Twin contacts (not shown) are provided on the bottom surface of the . The knob 2 provided on the upper surface of the slider 4 is aligned with the holes 6 provided on the upper surface of the cover included in the switch case 1, and protrudes through these holes 6. The holes 6 in the cover 5 correspond to the respective knobs 2.
Each is set up independently. That is, the respective knobs 2 are partitioned by the upper surface of the cover 5 and are located at positions significantly apart from each other. Further, a plurality of lead contacts 3 extend downward from near the bottom of both side surfaces extending in the longitudinal direction of the switch case 1 in parallel at intervals. The respective lead contacts 3 extend horizontally into the interior of the switch case 1 and face each other in the width direction of the switch case 1. Further, each lead contact 3 is held in an insulator portion of the switch case 1. Inside the switch case 1, the twin contacts of the slider 4 electrically connect or disconnect between the pair of lead contacts 3 in the width direction. That is, cover 5
By moving the knob 2 protruding from the hole 6 in the width direction of the switch case 1, circuit pattern switching operations such as interconnecting or disconnecting the paired lead contacts 3 can be performed.

[Problem that the invention attempts to solve]

However, when recognizing the set position of each knob 2, it is first done by reading the relative positional relationship with adjacent knobs 2, so if the knobs 2 are far apart, The problem is that it is difficult to read. Similarly, if each knob 2 is partitioned by a cover 5, the knobs 2
The length in the width direction perpendicular to the sliding direction is limited,
There is a problem in that the width of the knob 2 is narrow and it is difficult to slide the knob 2.

Therefore, an object of the present invention is to make the setting position display portion of a knob adjacent to the adjacent knob to facilitate mutual position comparison. Another object of the present invention is to provide a deep switch whose knob has a long operating surface to facilitate operation.

[Means and actions for solving problems]

According to the present invention, the slide structure has a plurality of knobs that are respectively attached to a plurality of sliders arranged in parallel inside a switch case and protrude to the outside of the switch case through holes provided in the switch case. In the deep switch, the plurality of ribs are arranged adjacent to each other without being partitioned by the switch case, and each of the plurality of ribs has a dimension that hardly creates a gap between adjacent knobs in a direction perpendicular to the sliding direction. A deep switch characterized by having the following features is obtained.

〔Example〕

1 to 6 show embodiments of the invention. The dip switch shown in FIG. 1 has a structure in which a switch case 11 is provided with ten sliders 12 and a knob 13. In the deep switch shown in FIGS. 2 to 6, a switch case 11 is provided with eight sliders 12 and a knob 13. However, the number of sliders 12 and knobs 13 may be increased or decreased as necessary depending on the circuit pattern. Note that the deep switch can be accessed from the outside of the switch case 11 by pressing the knob 1.
The point that the circuit pattern connected to the lead contact 14 is switched by sliding the switch 3 is the same as in the conventional case.

The dip switch of the illustrated embodiment has a rectangular parallelepiped switch case 11 formed by combining an insulator 15 and a cover 16. Inside the switch case 11, a plurality of sliders 12 are arranged adjacent to each other in parallel in the longitudinal direction. Each slider 12 is integrally formed with a knob 13 projecting from its upper surface. The knob 13 serves as a sliding operation and setting identification display section.
Each knob 13 is connected to the cover 1 of the switch case 11.
It protrudes inside one elongated hole 19 provided on the top surface of 6. The elongated hole 19 has stepped portions 17 at both ends in the operating direction of the knob 13, that is, in the direction shown by the arrow in FIG.
is formed to facilitate operation. Instead of the stepped portion 17, a notch facing each knob 13 may be formed at the edge of the elongated hole 19.

Twin contacts 20 are provided on the bottom surface of the slider 12. The twin contacts 20 are located inside the switch case 11 between a pair of lead contacts 14 facing each other in the width direction of the insulator 15,
Each is in contact with a pair of lead contacts 14. The lid contacts 14 are exposed from near the bottom of both side surfaces extending in the longitudinal direction of the switch case 11 and are bent downward, and are provided in parallel and spaced apart from each other in the longitudinal direction of the switch case 11.

Further, the knob 13 provided on the top surface of the slider 12 is rotated in a direction perpendicular to the sliding direction, that is, in a direction perpendicular to the sliding direction.
The length in the longitudinal direction of the knob 13 is made to be approximately the same as the mounting pitch of the knob 13 to maximize the width. As a result, adjacent knobs 13 are arranged with almost no gaps between them. Therefore, the set positions of the knobs 13 can be recognized very clearly in relation to each other.

Recesses 18 are formed on both end faces of the knob 13 in the sliding direction to facilitate operation with a jig such as a pen. The height of the protruding end of each knob 13 is set to be at the same level as the top surface of the cover 16 or lower. According to this, by applying a tape seal to the upper surface of the cover 16, it is possible to completely wash the cover 16 when cleaning flux, etc. that has adhered during soldering. Lead contact 14 is insulator 1
It is molded into 5. Further, the twin contacts 14 are fixed by being thermally crimped with protrusions protruding from the lower surface of the slider 12. This twin contact 2
The slider 12 including the knob 13 and the cover 16
The insulator 15 is assembled by protruding the knob 13 into the elongated hole 19 of the cover 16 and welding the insulator 15 and the cover 16 together.

In this way, the switch case 11 is operated by sliding the knob 13 from the outside.
A pair of lead contacts 14 facing each other in the width direction of
ON/OFF operation is available.

[Effect of idea]

As described above, according to the present invention, adjacent setting positions of each knob can be easily recognized by comparing the positions of each knob with each other, and sliding operation is also facilitated by increasing the width of the knob. It becomes easier.
