Liquid level sensor of the prior art utilizes heat-shrink tube to fix two copper hinge lines, and wherein a copper hinge line directly is connected on the resistor disc; Another root copper hinge line is drawn a lead and is connected on the slide plate that touches with above-mentioned resistor disc.But can produce phenomenon loosening, that rupture or come off through soaked with liquid heat-shrink tubes such as long-time gasoline, thereby the reliability of liquid level sensor performance is exerted an influence.And, must in advance heat-shrink tube be socketed on the lead when making the heat-shrink tube lead, and when assembling, carry out the line-spacing adjustment, use the heat gun stationary heat draw at last, this mode of operation is too loaded down with trivial details.Furthermore, the manufacturing materials of traditional liquid level sensor, productive labor cost height, and also the production time is long.
The utility model content
The purpose of this utility model is to provide a kind of and improves the reliability of positioning of copper hinge line and simplify the liquid level sensor that copper cuts with scissors traditional thread binding allotment of labor's skill.
The utility model comprises resistor disc skeleton, resistor disc, slide plate, lever support, first copper stranded conductor and second copper stranded conductor, and the resistor disc skeleton comprises a base plate and the biside plate that is arranged on the base plate, and the outside of biside plate is respectively arranged with cable clamping interface; Resistor disc is arranged on the base plate between the biside plate; The base plate of the resistor disc skeleton between the biside plate is provided with joint pin, and lever supports the two ends that can pivotally be connected joint pin; Slide plate is connected in the lever support and the front end and the resistor disc of slide plate touch, and first copper stranded conductor and resistor disc interconnect, and also are provided with lug plate on the resistor disc skeleton, and second copper stranded conductor is welded on the lug plate, and slide plate and lug plate interconnect by electrical connector.
Improved liquid level sensor with wire bonds on lug plate, in assembling, lug plate is stuck on the skeleton and with electrical connector then and is connected with lug plate, electrical connector is electrically connected with slide plate again, reaches the purpose that lead is electrically connected with slide plate, and this mode is promptly convenient simply again.And, increased the phenomenon that fastness can not become flexible, ruptures or come off through the immersion of liquid such as long gasoline simultaneously, changed the mode of utilizing heat-shrink tube fixed copper twisted wire in the prior art, strengthened liquid level sensor application reliability, reduced the productive labor cost, reduced the production time.
First copper stranded conductor is arranged in the cable clamping interface in the resistor disc skeleton side plate outside, and lug plate is arranged on the resistor disc skeleton of same side plate inboard.
Perhaps, first copper stranded conductor is arranged in the cable clamping interface in the resistor disc skeleton side plate outside, and lug plate is arranged on the resistor disc skeleton of another side plate inboard.
Electrical connector is a power spring, and power spring is enclosed within on the joint pin; One end of described power spring is welded on the slide plate, and the other end is welded on the lug plate.
Power spring can be saved the material cost of production as electrical connector.And spring housing is in the space that can make full use of on the joint pin on the skeleton.
