Abstract
The utility model discloses a main contact head with diminutive resistor, particularly consisting of a box-shaped bracket and a main contact head arranged in the bracket, which is characterized in that: a spring is arranged at the bottom of the box-shaped bracket, and a main contact head is arranged on the spring. The utility model has reasonable structure and skillful conception. The spring arranged beneath the contact guarantees the reliable connection of the contact and the static contact, thereby reducing the contact resistance, which has great value of popularization.
Description
Technical field
The utility model relates to the appliance switch technical field, specifically, relates to a kind of main contact of on load tap changer.
Background technology
In existing on load tap changer, main contact has various ways, and use more have following two kinds: 1, at contact base two contacts are housed, link to each other with contact base by being flexible coupling, contact base also plays the conducting function of current.2, the fixed contact that the inboard is and moving contact switches, the outside is a contact chip, has to be flexible coupling between fixed contact and the contact chip to link to each other.From last introduction as can be seen, in the existing on load tap changer, it is unreliable that the contact contacts with fixed contact, thereby cause contact resistance excessive.
Summary of the invention
The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, and the multiconductor parallel connection, the contact can reliably compress the little main contact of contact resistance that contacts with fixed contact.
For achieving the above object, the utility model adopts following technical scheme: the main contact that a kind of contact resistance is little, mainly by box-like support and place the main contact in it to form, it is characterized in that: the bottom of box-like support is provided with spring, and spring is provided with main contact.
Because adopt such scheme, be not difficult to draw as drawing a conclusion: the utility model is rational in infrastructure, is skillfully constructed, the spring that the bottom, contact is provided with can make the contact reliably compress with fixed contact and contact, thereby has reduced contact resistance, has promotional value.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a cross-sectional view of the present utility model.
Embodiment
Referring to accompanying drawing, the bottom of box-like support 20 is equipped with spring 50, and the top of spring 50 is provided with four main contacts 10, and the middle part of main contact 10 is provided with mounting hole 11, is equipped with pilot pin 40 in it, plays the contact point guiding effect.Wherein, the both sides of each main contact 10 are provided with and are flexible coupling 30, be flexible coupling 30 to turn up, by screw in compression in box-like support 20 outsides.The box-like support plays the effect of conducting electric current simultaneously.
Claims (1)
