Abstract
The utility model relates to a connection structure of a speed regulating switch circuit board and terminals, which comprises a base assembly and a cover plate which is arranged on one side of the base assembly, wherein the bottom of the cover plate is provided with three terminals and the other side of the base assembly is provided with a speed regulating circuit board and a cooling plate which is in contact with the speed regulating circuit board. Three through holes corresponding to the terminals are respectively arranged in the base assembly, springs are respectively arranged in the three through holes, one end of the spring is respectively contacted with the terminals and the other end of the spring is respectively contacted with connecting points which are arranged on the speed regulating circuit board. The utility model has the advantages of low structure cost, convenient assembly, high connection reliability, safe operation and long service life.
Description
Technical field
The utility model relates to a kind of speed-regulating switch, relates in particular to a kind of speed governing wiring board of speed-regulating switch and the draw bail between the terminal.
Background technology
In traditional speed-regulating switch, connecting mode between its speed governing wiring board and the switch terminal mainly contains two kinds: the crimping of a kind of employing reed, being about to reed is provided with between speed governing wiring board and the switch terminal, it is comparatively convenient that this connecting mode is installed, but the contact effect is not ideal during crimping, the long-term use, and reed easily deforms, and the space that reed occupies is bigger, thereby has influence on the volume of whole switch; Another kind promptly adopts welding manner, though its space that occupies is less, and during welding, fragile speed governing wiring board, complex manufacturing technology.
Summary of the invention
The purpose of this utility model is to provide the draw bail of a kind of speed-regulating switch wiring board and terminal, and it is easy for installation, connect between wiring board and the terminal safer and reliable, and can conserve space.
For realizing the purpose of this utility model, the draw bail of a kind of speed-regulating switch wiring board and terminal, comprise base assembly, be arranged on the cover plate of base assembly one side, the bottom of cover plate is provided with three terminals, the opposite side of base assembly is provided with speed governing wiring board and heating panel contacted with it, offer three through holes corresponding respectively in the described base assembly with terminal, be respectively arranged with spring in three through holes, one end of spring contacts with terminal respectively, and the other end then contacts with tie point on the speed governing wiring board respectively.
The beneficial effects of the utility model are: this structure low cost of manufacture, and easy to assembly, and the coupling reliability height, safe in utilization, the life-span is long.
Description of drawings
Be described in further detail below in conjunction with the draw bail of accompanying drawing the utility model speed-regulating switch wiring board and terminal:
Fig. 1 is the draw bail exploded perspective view of the utility model speed-regulating switch wiring board and terminal;
Among the figure: 1, base assembly, 2, cover plate, 3, terminal, 4, terminal, 5, terminal, 6, the speed governing wiring board, 7, heating panel, 8, through hole, 9, spring.
Embodiment
As shown in Figure 1, the draw bail of a kind of speed-regulating switch wiring board and terminal, comprise base assembly 1, be arranged on the cover plate 2 of base assembly 1 one sides, the bottom of cover plate 2 is provided with three terminals 3,4,5, the opposite side of base assembly 1 is provided with speed governing wiring board 6 and heating panel 7 contacted with it, offer three and terminal 3 in the base assembly 1,4,5 corresponding respectively through holes 8, be respectively arranged with spring 9 in three through holes 8, one end of spring 9 respectively with terminal 3,4,5 contact, the other end then contacts with tie point on the speed governing wiring board 6 respectively, and the surface of described spring 9 all is coated with one deck silver, to improve its electric conductivity.
In the draw bail of the utility model speed-regulating switch wiring board and terminal, be connected by adopting three springs 9 to make respectively between terminal 3,4,5 and the speed governing wiring board 6, thereby simplified the draw bail between them, be convenient to the product assembling, and can improve the reliability that they connect.
