Embodiment Construction

[0017] figure 1 The starter shown in includes a base 1 made of insulating material, and only its mounting base part is shown in the figure. Several current paths pass through the base, each equipped with a double break contact arrangement with separable contact pairs. In this way, each electrode path comprises two fixed contacts 12 and 16 arranged on fixed contacts 18 and 17 connectable to terminals. It also includes two movable contacts 5 and 11 that cooperate with fixed contacts 12 and 16, and 5 and 11 are welded on the contact bridge to become a movable bridge contact 6, forming a double-pole polarity switch. Other components matching the device can also be seen in the figure, such as base 14, base 1 and arc extinguishing chamber 2, etc.

[0018] Figure 2-5 An embodiment of the double break contact arrangement of the present invention is shown in further detail. The bridge contact 5 can be directly loaded from the top of the support seat 19, and the bridge contact can ...

Abstract

Each electrode in the base comprises the moveable bridge type contact and the contact force spring. The support seat on the base is utilized to fix the said electrode. There is the axle pin in the support seat. The force spring and the movable bridge type contact are put on the axle pin in the sequence. In the process of assembling the contact device, the force spring is in the natural relaxation state all the time without need of special tool so that the assembling process does not cause the damage of the parts.

Description

technical field [0001] The invention relates to a starter double-break point contact device, which includes a base, and each electrode includes a movable bridge-shaped contact matched with a fixed contact and a contact pressure spring, and the bridge-shaped movable contact is The contact holder is pressed against the pressure spring, and the contact holder is fixed on a mechanism for opening and closing the contacts. Background technique [0002] The above-mentioned system is well known, and it is combined with the arc extinguishing assembly, and has the function of opening the corresponding electrode contact in response to the electrical accident command transmitted by random or program to the opening and closing mechanism. Using such a system has the added feature of ease of assembly and operation of the starter. The Chinese Invention Patent 93102542.7 application publication has improved the existing technology. The button of the bridge contact...
