Abstract

The utility model relates to a full plastic sealing switch type potentiometer which mainly comprises a rotating shaft, a switch cam, an upper connecting seat and a base, wherein the switch cam is clamped, buckled and connected to the rotating shaft, and the rotating shaft together with the switch cam is sleeved in a rotating hole of the upper connecting seat together; the head part of the rotating shaft is pressed with a cover cap of the rotating shaft by adopting the ultrasonic melting and pressing process of an injection molding component, so that the head part of the rotating shaft and the cover cap of the rotating shaft are connected into a whole; the bottom end of the other side of the rotating shaft is provided with a reed; moreover, the reed is positioned between the rotating shaft and the base; two soldering lugs for external wiring are arranged on the base, and the base and the upper connecting seat are connected into a whole by adopting the ultrasonic melting and pressing process of the injection molding component in a full plastic sealing type; and the full plastic sealing switch type potentiometer not only has the characteristics of stable performance, good effect of resisting high voltage, high sealing performance, low cost and the like but also has the effects of dust prevention, moisture prevention and the like.

Description

Overall plastic envelope switching regulator potentiometer

Technical field

The utility model relates to a kind of switching regulator potentiometer, especially a kind of overall plastic envelope switching regulator potentiometer belongs to a kind of electronic devices and components.

Background technology

Potentiometer is the electronic devices and components that a kind of application is quite popularized, can there be bigger difference in its structure according to the difference of making, and wherein potentiometer with switch is widely used in all kinds of electronic potentiometers, but potentiometer with switch complex structure in the market, cost height, and less stable.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of stable performance, high voltage withstanding effective, sealing property is high, cost is low overall plastic envelope switching regulator potentiometer are provided.

The purpose of this utility model is finished by following technical solution, and it mainly comprises rotating shaft, switch cam, first line of a couplet seat, pedestal, and described switch cam buckle is connected in the rotating shaft, and this rotating shaft is placed in the commentaries on classics hole of first line of a couplet seat together with switch cam; Adopt moulding ultrasonic wave compression technology to be suppressed with rotating shaft block at described shaft head, thereby shaft head and rotating shaft block are connected as a single entity; Opposite side bottom in described rotating shaft is provided with a reed, and this reed is between rotating shaft and pedestal; Be provided with two weld tabs that are used for external connection on this pedestal, described pedestal and first line of a couplet seat adopt moulding ultrasonic wave compression technology to be complete plastic sealed being connected as a single entity.

As preferably, described switch cam one end is the wedge angle type, in it for emptying type, with this end be that the corresponding first line of a couplet seat of wedge angle type switch cam inwall is injected with two raised lines, this switch cam is the switching regulator activity with first line of a couplet seat and contacts.

As preferably, described base interior center is provided with a circular hole, and this circular hole is spacing with the end of rotating shaft and is connected.

The utility model adopts process procedures such as integral molded plastic, whole assembling, and adopt moulding ultrasonic wave compression technology to come the substituted metal die casting simultaneously, make first line of a couplet seat and pedestal be integral structure, properties of product and quality of stability have not only been improved, realized energy-saving and cost-reducing improvement target simultaneously, also save the use of a large amount of non-environmental protection materials, had stable performance, high voltage withstanding effective, characteristics such as sealing property is high, cost is low.

Embodiment

Label in the accompanying drawing is respectively: 1, rotating shaft, 2, switch cam, 3, first line of a couplet seat, 4, the rotating shaft block, 5, reed, 6, pedestal, 7, weld tabs, 31, change the hole, 32, raised line, 61, circular hole.

Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying

drawing

1,2,3,4, the utility model mainly comprises rotating shaft 1, switch cam 2, first line of a couplet seat 3, pedestal 6, described switch cam 2 buckles are connected in the rotating shaft 1, and this rotating shaft 1 is placed in the commentaries on classics hole 31 of first line of a couplet seat 3 together with switch cam 2; Adopt moulding ultrasonic wave compression technology to be suppressed with rotating shaft block 4 at described rotating shaft 1 head, thereby rotating shaft 1 head and rotating shaft block 4 are connected as a single entity; Be provided with a reed 5 in the opposite side bottom of described rotating shaft 1, and this reed 5 is between rotating shaft 1 and pedestal 6; Be provided with two weld tabs 7 that are used for external connection on this pedestal 6, described pedestal 6 adopts moulding ultrasonic wave compression technology to be complete plastic sealed being connected as a single entity with first line of a couplet seat 3.And the utility model is the metalwork except weld tabs 7, and other are, and plastic material makes, and greatly reduce production cost like this, and performance increases substantially also.

Described switch cam 2 one ends are the wedge angle type, it is interior for emptying type, its purpose is that the elasticity of closed angle end is better, with this end be that wedge angle type switch cam 2 corresponding first line of a couplet seat 3 inwalls are injected with two raised lines 32, this switch cam 2 and first line of a couplet seat 3 are that switching regulator is movable to be contacted.In active procedure, can produce switch and ring sense, be convenient to the user and distinguish the residing situation state of potentiometer at that time.

Described pedestal 6 inside center are provided with a circular hole 61, and this circular hole 61 is spacing with the end of rotating shaft 1 and is connected.

The utility model adopts moulding ultrasonic wave compression technology to be the complete plastic sealed structure that is connected as a single entity first line of a couplet seat and pedestal, not only has stable performance, high voltage withstanding effective, characteristics such as sealing property is high, cost is low, can also play effects such as dustproof, protection against the tide.
