Vehicle circuit breaker

1. A vehicle circuit breaker, comprising:

a housing;

an electrode assembly, disposed in said housing and comprising a first electrode configured on said housing and a second electrode configured on said housing, said second electrode positioned at one side of said first electrode;

a first conducting element, configured on said first electrode, positioned inside said housing, and being a silver contact;

an electrode connection portion, configured on said second electrode and positioned inside said housing;

a first insertion portion, configured on said first electrode and positioned outside said housing;

a second insertion portion, configured on said second electrode and positioned outside said housing;

a bimetal conducting sheet, configured inside said housing and positioned correspondingly to said electrode assembly;

a plurality of conducting concave portions, configured on two respective sides of said bimetal conducting sheet, the depression depth of said conducting concave portions being 0.15 to 0.4 mm, and said bimetal conducting sheet is connected to said electrode connection portion through one of said conducting concave portions;

a second conducting element, configured on another of said conducting concave portions and positioned correspondingly to said first conducting element, thereby allowing said second conducting element to contact and electrically connect with said first conducting element, and said second conducting element being a silver contact;

a blocking element, movably configured inside said housing and positioned between said electrode assembly and said bimetal conducting sheet;

an elastic element, said blocking element and electrode assembly respectively connected to two ends thereof, and said blocking element adapted to move to between said first conducting element and second conducting element through the elastic force of said elastic element; and

a pressing portion, configured on said blocking element and passed out of said housing.

2. The breaker according to claim 1 , wherein said housing has a bearing element and a covering element covered on said bearing element, and said electrode assembly is configured on said bearing element.

3. The breaker according to claim 2 , wherein at least one first connection portion is configured on said bearing element.

4. The breaker according to claim 3 , wherein at least one second connection portion correspondingly connected to said first connection portion is configured on said covering element.

5. The breaker according to claim 1 , wherein said blocking element has a blocking limit adapted to allow said blocking element to be slid and limited on said electrode assembly through said blocking limit.

6. The breaker according to claim 5 , wherein said electrode assembly has an electrode limit adapted to allow said blocking limit to be slid and limited thereon.

7. The breaker according to claim 1 , wherein said electrode connection portion is connected to said conducting concave portion by means of spot welding or riveting.

8. The breaker according to claim 7 , wherein said conducting concave portion has a metal gasket adapted to facilitate said spot weld connection of said electrode connection portion with said conducting concave portion.

9. The breaker according to claim 1 , wherein said bimetal conducting sheet is deformed through temperature change to drive said second conducting element to be in contact with or separated from said first conducting element.

10. The breaker according to claim 1 , wherein said housing is configured with at least one slip skip.
