があつた。(Problems to be Solved by the Invention) However, as mentioned above, the conventional pressure switch has a structure in which a pressure receiving pin (piston) that receives the pressure of the pressure circuit is housed in the switch housing (body). Since the tip of the switch housing was attached to the member to which the switch is mounted in the part that accommodates the pressure pin, the switch housing (body) becomes large, resulting in high costs and requiring a lot of space for transportation and storage. In addition, the amount of protrusion of the pressure switch from the member to which the switch is attached increases, resulting in an increase in the space required for installation.

けられている構造とした。 To achieve this purpose, the pressure switch mounting structure of the present invention includes a switch housing, a fixed terminal fixed to one end of the switch housing,
With respect to the fixed terminal, a movable contact is normally held in a non-contact state by a spring in an internal hole formed in the switch housing, a pressure receiving pin is provided integrally with the movable contact, and a pressure receiving pin is provided near the opening of the internal hole. The movable contact is provided with a through hole having a smaller diameter than the movable contact and a larger diameter than the pressure receiving pin, and with the pressure receiving pin passing through the through hole and protruding outward from the interior hole of the switch housing. A pressure switch is equipped with a snap spring that is held in the switch housing in a fixed state, and a pressure receiving pin protruding from the switch housing is formed on the switch mounting member to introduce pressure from the pressure circuit into the switch mounting member. It has a structure in which it is attached so that it can be slid freely into the pressure receiving pin slide hole.

ライド自在に挿入させた状態で、スイツチ取付相
手部材に固定する。(Function) When installing the pressure switch, the pressure receiving pin protruding from the switch housing is slidably inserted into the pressure receiving pin slide hole formed in the switch mounting member, and then fixed to the switch mounting member.

ことができるものである。 During this installation, the pressure receiving pin passes through a through hole with a larger diameter than the pressure receiving pin formed in the snap spring, so there may be some dimensional misalignment between the switch housing and the pressure receiving pin in the direction orthogonal to the axis. However, this deviation can be absorbed by the difference in diameter between the pressure receiving pin and the through hole. In other words, since the switch housing and the switch mounting member are separate bodies, dimensional errors such as misalignment of the axis tend to occur between the two, but as mentioned above, slight dimensional misalignment can occur due to It can be absorbed by the difference in diameter.

ジングから突出している分だけスイツチハウジン
グをコンパクト化できる。 Since the pressure-receiving pin protrudes from the switch housing, the switch housing must be attached to the switch mounting member at a position closer to the fixed terminal than the position where the pressure-receiving pin is provided. Compared to the prior art, the amount of protrusion of the pressure switch in the attached state is reduced by the amount that the pressure receiving pin is inserted into the member to which the switch is attached. Further, the switch housing can be made more compact by the amount that the pressure receiving pin protrudes from the switch housing.

ハウジングから脱落することはない。 In addition, the movable contact that is integrated with the pressure receiving pin is held securely in the internal hole by a snap spring, so even if the pressure receiving pin protrudes from the switch housing, it can be easily removed during transportation, storage, and installation of the pressure switch. The pressure receiving pin will not fall off from the switch housing during removal.

When this occurs, the system senses this and activates a device that increases the engine speed to prevent the engine from stalling.

なつている。 The movable contact 30 is provided integrally with the pressure receiving pin 40 by fitting the pressure receiving pin 40 as shown in the figure, and is resiliently biased by a spring 50 in a normal state, and is located near the opening end of the internal hole 14. It is placed apart from the fixed terminal 20 at a position regulated by a snap spring 60 provided inside, and when in contact with the fixed terminal 20, the body is grounded via the pressure receiving pin 40 and becomes energized. A device that increases engine speed is activated.

自在に挿入保持されている。 In addition, the pressure receiving pin 40 is inserted into the pressure receiving pin slide hole 5 formed at the distal end of the hydraulic circuit 1 of the mating member 2 so that the pressure receiving surface 41 at the distal end receives the pressure of the hydraulic circuit 1 in the illustrated mounting state. It is inserted and held so that it can slide freely.

合が生じることがない。 At this time, since the switch housing 10 and the mating member 2 are separate bodies, the centers of the switch housing 10 and the pressure receiving pin slide hole 5 may be misaligned due to manufacturing errors or installation errors. However, since the pressure receiving pin 40 is allowed to be displaced in the radial direction by the through hole 61 of the snap spring 60, this displacement is absorbed by the displacement of the pressure receiving pin 40, and no malfunction occurs in the operation.

扱に支障はない。 Note that the pressure receiving pin 40 is attached to the switch housing 10.
Even if the pressure receiving pin 40 is not slid and held by
Since the movable contact 30, which is integral with the switch A, is prevented from coming off by the snap spring 60, it will not be left behind on the mating member 2 and disassembled, and there will be no problem in handling the switch A.

パクトにできる。 As described above, in the mounting structure of the pressure switch A of this embodiment, the pressure receiving pin 4 is attached to the switch housing 10.
The switch housing 10 can be made compact since the outer circumference of the switch housing 10 is hardly covered and the overall length is short.

ペースを小さくすることができる。 Furthermore, the mating member 2 of the switch housing 10
Since the attachment to the movable contact 30 is carried out at the small diameter part 11 at the outer position of the movable contact 30, the protrusion from the mating member 2 is smaller compared to the conventional attachment at the outer position of the middle part or tip of the pressure receiving pin. This allows the installation space to be reduced.

Even if the structure is such that the pressure receiving pin 40 is not slid and held, as mentioned above, the center may shift due to accuracy errors and malfunctions may occur in the operation of the pressure receiving pin 40, or the pressure switch A may become loose if it is not attached to the mating member 2. There is no problem in handling the product.
