Switch device mounting structure

Abstract

A switch device structure includes at least one contact seat having a first end wall, a second end wall, two sidewalls, an upper section and a bottom section to together define a cavity for arranging a contact assembly. Each of the first and second end walls of the contact seat has a protruding assembling section and an oblique socket directed to the assembling section. The switch device structure includes a contact support equipped with a fixing board. The contact support is formed with latch sections detachably latched with the assembling sections. An operator can use a tool to directly pass through the oblique socket to unlatch the latch section from the assembling section to quickly install/uninstall the contact seat and the contact support. This solves the problem of the conventional switch device that it is troublesome and time-consuming to install/uninstall the contact seat and the contact support.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(5) Please refer to FIGS. 1, 2 and 3. According to a preferred embodiment, the switch device structure of the present invention is a restriction or travel switch device for illustration. The switch device structure has three contact seats 10 side by side assembled with each other and a contact support 20 latched with the contact seats 10. The contact support 20 is fixed with a fixing board assembly or fixing board 40 by screws 30. The fixing board 40 permits an operation rod 50 to extend into the contact support 20 to touch the contact seat 10. This achieves an effect similar to the conventional restriction switch.

(6) In this embodiment, the contact seat 10 has an insulation case body defined with an axis . The contact seat 10 has a first end wall 11, a second end wall 12, two sidewalls 13, an upper section 14 and a bottom section 15 to together define a cavity 16 for arranging a contact assembly 55 therein. The contact seat 10 has an assembling section 17 protruding from the first end wall 11 and/or the second end wall 12 and an oblique socket 18 directed to and related to the assembling section 17. The assembling section 17 includes a shoulder section 17A positioned near the bottom section 15 in a direction away from the axis . In addition, two ends of the contact support 20 are respectively formed with latch sections 21 corresponding to the assembling section 17 and the oblique socket 18. As shown in the drawings, multiple continuously arranged latch sections 21 are formed at two ends of the contact support 20 in accordance with the number of the contact seats 10. The assembling sections 17 of the contact seats 10 are detachably latched with the latch sections 21 to form an integrated structure.

(7) To speak more specifically, each latch section 21 of the contact support 20 has two protruding cantilevers 22 and a connection section 23 connected between the two cantilevers 22 to together define a space 24. Accordingly, the latch section 21 has a U-shaped (cross section) configuration with elasticity. As also shown in the drawings, the oblique socket 18 is a structure inclined from the first and second end walls 11, 12 to the axis . The oblique socket 18 includes a slope 19 inclined to the axis for supporting and guiding a tool to insert into the contact seat 10. (This will be further described hereinafter.)

(8) FIG. 2 also shows that the contact support 20 is formed with at least one stake 25 positioned between the adjacent latch sections 21 and having trapezoidal cross section. The edge of the fixing board 40 is formed with notches 41 in alignment with the stakes 25 for assembling or inlaying the stakes 25. Accordingly, the fixing board 40 can be securely assembled with the contact support 20.

(9) FIG. 3 especially shows that an operator can directly operate the latch sections 21 to latch with the assembling sections 17 of the contact seat 10 to assemble the contact support 20 with the contact seat 10. As shown in the drawings, the assembling section 17 is relatively positioned in the space 24 of the contact support 20 with the connection section 23 pressed onto the assembling section 17. In this case, the connection section 23 is positioned in the inclined path of the oblique socket 18.

(10) Please refer to FIG. 4. An operator can use a tool 60 (such as a screwdriver) to pass through the oblique socket 18 and directly push away the connection section 23 of the latch section 21 from the assembling section 17 with the slope 19 serving as a (force application) fulcrum. Accordingly, the contact seat 10 and the contact support 20 can be quickly installed/uninstalled. This improves the shortcoming of the conventional switch device that it is necessary to troublesomely and time-consumingly tighten over a dozen screws or install multiple spring lock washers for assembling/disassembling the contact seat and the contact support.

(11) According to the above, in the condition that the structure is simplified and the operation is facilitated, in comparison with the conventional switch device, the switch device structure of the present invention has the following advantages: 1. The contact seat 10, the contact support 20 and the relevant components and structures have been redesigned, and each contact seat 10, the contact support 20 and the relevant fixing structures latched with each other have been specifically considered to be different from the conventional switch device and change the usage and operation form thereof. For example, the first and second end walls 11, 2 of the contact seat 10 are formed with assembling sections 17 in a direction away from the axis . The first and second end walls 11, 2 of the contact seat 10 are formed with oblique sockets 18 in a direction to the axis . Two ends of the contact support 20 are formed with latch sections 21, cantilevers 22, connection sections 23 and spaces 24, whereby the latch sections 21 have elasticity. This obviously changes the structures and textures of the conventional switch device and solves the problem of the conventional switch device that when replacing or install/uninstall the switch device, it is necessary to troublesomely and time-consumingly tighten over a dozen screws or install multiple spring lock washers for assembling/disassembling the contact seat and the contact fixing support. 2. The latch section 21 of the contact support 20 permits an operator to directly latch and assemble the contact support 20 with the assembling section 17 of the contact seat 10 or use a tool 60 to push away the latch section 21 under the guide of the oblique socket 18 with the slope 19 serving as a fulcrum. Accordingly, the contact seat 10 and the contact support 20 can be easily and quickly assembled/disassembled. Especially, in comparison with the conventional contact seat structure, the structural design and assembling pattern of the contact seat 10 and the contact support 20 allow the upper section 14 and/or bottom section 15 of the contact seat 10 form an as closed as possible structure. This minimizes the possibility of mis-touch that often takes place in the conventional switch device.

(12) In conclusion, the switch device structure of the present invention is different from the conventional switch device in space form and is advantageous over the conventional switch device. The shift assembly structure of switch device of the present invention is novel and inventive.

(13) The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
