Technical Field
The utility model relates to the technical field of switches, in particular to a welding type micro-switch with stable stroke for a high-pressure cleaning machine.
Background
Along with the continuous improvement of living standard, the use of the high-pressure cleaning machine in daily life of people is more and more common, and the micro switch is used as a control switch on the high-pressure cleaning machine, so that the performance of the micro switch is required to be more stable and reliable, and the high-efficiency, smooth and stable use of the cleaning machine equipment production is ensured. The performance requirement of the high-pressure cleaning machine on the micro-switch is also an important aspect besides the conductive function, and the stroke stability of the micro-switch is mainly determined by the position of the bracket part. In actual production, the connection between the switch terminal and the lead is usually realized by adopting a plug bush connection or a direct welding mode, the plug bush connection is quick and convenient, but not firm and reliable enough and is easy to generate heat, the direct welding mode is firm and reliable and is not easy to generate heat, but because the support is fixed on the base through a groove on the side edge of the support and is clamped on a boss on the edge of the base, the position is very close to the welding point, if the welding method or the technology is improper, the plastic of the base is easy to melt, so that the support part is displaced, the change of the switch stroke is caused, and the change of the switch stroke often causes the failure of the switch and the reworking of the production, and the use is unstable and not durable. Based on the above, it is especially necessary to design a novel welding type micro-switch with stable stroke for a high-pressure cleaning machine.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model aims to provide the welding type micro switch with stable stroke for the high-pressure cleaning machine, which has the advantages of simple structure, reasonable design, convenient manufacture, reduced production cost, stable and unchanged switch stroke after terminal welding, smooth production, improved quality stability and easy popularization and use.
In order to achieve the above object, the present utility model is realized by the following technical scheme: the welding type micro switch comprises a base, a button, a bracket terminal part, a contact pin terminal part and a movable contact piece part, wherein the bracket terminal part and the movable contact piece part are arranged in the base; the body of the bracket terminal part is provided with a positioning groove and a raised positioning block, the base is provided with a positioning boss and a positioning blind hole, the positioning groove is clamped on the positioning boss, the positioning block is inserted in the positioning blind hole, and the bracket terminal part is fixed on the base.
Preferably, two contact pin terminal members are provided, and the two contact pin terminal members are provided on a short side surface of the base.
Preferably, the positioning block is arranged at the top end of the bracket terminal part, and the base is provided with a corresponding positioning blind hole for fixing the positioning block on the bracket terminal part.
The utility model has the beneficial effects that: the device can ensure that the switch travel is stable and unchanged after the terminal is welded with the external lead, reduce the cost and ineffective labor caused by the change of the switch travel due to welding, improve the quality stability of products, ensure the smooth production, and has convenient manufacture and wide application prospect.

The utility model is described in detail below with reference to the drawings and the detailed description;
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a schematic view of the structure of the terminal member of the bracket of the present utility model;
fig. 3 is a schematic structural view of the base of the present utility model.
Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
Referring to fig. 1-3, the present embodiment adopts the following technical scheme: the utility model provides a stable welding formula micro-gap switch of stroke for high pressure cleaner, including base 1, button 2, support terminal part 3, contact pin terminal part 4 and movable contact piece part 5, support terminal part 3, movable contact piece part 5 are installed together inside base 1 after the equipment, and the side of base 1 is provided with two contact pin terminal parts 4, and button 2 is still installed to base 1 inside, and button 2's bottom contacts with movable contact piece part 5's afterbody, and the during operation is through pressing button 2 to drive movable contact piece part 5's upset, and then reaches the purpose of control circuit break-make.
It should be noted that the body of the bracket terminal component 3 is provided with a positioning groove 301, a raised positioning block 302, the positioning block 302 is disposed at the top end of the bracket terminal component 3, the base 1 is provided with a positioning boss 101 and a positioning blind hole 102, the positioning blind hole 102 is matched with the positioning block 302 in size and position, and the bracket terminal component 3 is fixed on the base 1 by clamping the positioning groove 301 on the positioning boss 101 and inserting the positioning block 302 into the positioning blind hole 102.
In this embodiment, a protruding positioning block 302 is disposed at the top end of the bracket terminal 3, and a corresponding positioning blind hole 102 is disposed on the base 1 for fixing the positioning block 302 on the bracket terminal 3. The conventional bracket base connection structure only clamps the positioning boss 101 through the positioning groove 301, fixes the bracket terminal part 3 on the base 1, and shifts if the positioning boss 101 is damaged after welding, so that the switch stroke is changed. In this way, the positioning block 302 and the positioning blind hole 102 are newly added, when the bracket terminal part 3 is arranged on the base 1, the positioning block 302 is inserted into the positioning blind hole 102, and a positioning is added to the bracket on the base part, so that even if the positioning boss 101 is damaged after welding, the bracket is not shifted, and the switch stroke is not changed.
According to the concrete implementation mode, the fixed point of the bracket on the base is increased, the effect of limiting the position of the bracket part on the base part is achieved, so that even if the plastic at the edge of the base is heated and melted after welding, the bracket part cannot shift to cause the change of the switch stroke, the stable and unchanged switch stroke after terminal welding is ensured, the smooth production is ensured, meanwhile, the production cost cannot be increased, the cost and invalid labor caused by the change of the switch stroke due to welding are reduced, and the concrete implementation mode has a wide market application prospect.
