Abstract
The invention discloses the movable contact spring of the good relay of a kind of anti-contact cementability, it comprises body (1), body (1) offers the first otch (2) and the second otch (3), and the part be positioned between the first otch (2) and the second otch (3) of body (1) is moving contact installation portion (4).
Description
Technical field
The present invention relates to relay technical field, is specifically a kind of movable contact spring of relay.
Background technology
There is a kind of movable contact spring of relay at present, it comprises body, by offering L shape or quadrant arc otch forms a moving contact installation portion on body, owing to only there being an otch, and be mainly positioned at the side of moving contact installation portion, like this, need larger power to promote movable contact spring to swing, the left side of moving contact installation portion is positioned at for otch main part, movable contact spring is promoted by two ends, promote the left and right end that contact site is respectively movable contact spring, about this, end lays respectively at the moving contact installation portion left and right sides, because otch main part is positioned at the left side of moving contact installation portion, the part being positioned at the right side of moving contact installation portion of body is caused substantially to be connected as a single entity with moving contact installation portion, the power that so promoting right-hand member needs just must be greater than the power promoting left end needs, but the mechanism of applied thrust only can apply a power, left and right end can not be distinguished, therefore the mechanism of applied thrust is that the power promoting right-hand member needs is as the criterion when exerting a force, situation character when the problem that otch main part produces when being positioned at the right side of moving contact installation portion is example with above-mentioned left side is consistent, in a word, the mechanism of applied thrust is that the maximum power promoting movable contact spring needs is as the criterion when exerting a force, again because there is certain temperature after sound contact, like this, in long-term work, larger thrust can cause the anti-contact cementability of movable contact spring poor, namely larger thrust can cause the moving contact be arranged on moving contact installation portion tightly to bond together can not easily separate with fixed contact.
Summary of the invention
The technical problem to be solved in the present invention is, provides the movable contact spring of the relay that a kind of anti-contact cementability is good.
Technical scheme of the present invention is, the movable contact spring of invention relay, and it comprises body, and body offers the first otch and the second otch, and the part between the first otch and the second otch of body is moving contact installation portion.
After adopting said structure, the present invention compared with prior art, have the following advantages: owing to having two otch, and be positioned at the both sides of moving contact installation portion, so the part being positioned at the moving contact installation portion left and right sides of body is not all connect together with moving contact installation portion large area, like this, the power swung for promoting movable contact spring being applied to the left and right end of movable contact spring will reach unanimity and the strength needed is less, therefore the present invention has the good advantage of anti-contact cementability, in addition, because strength is less, be conducive to improving movable contact spring and cooperatively interact the reliability of its Surrounding Parts of work and durability with movable contact spring.
As improvement, the first otch is sequentially formed by connecting by arch section and straight line portion; Second otch is linear incision, and this syndeton is comparatively compact.
As further improvement, straight line portion and second otch of the first otch are parallel to each other, and this structure processing is simple, operationally, and uniform force.
As further improvement, straight line portion and second otch of described first otch are angular cut, and this structures slope certain angle reduces to less by causing the loss of strength of movable contact spring because of otch.
As further improvement, the angle of inclination of angular cut is 45 degree, and this angle of inclination is preferred value, and the present invention can be made to have good performance.

Shown in figure, 1, body, the 2, first otch, 2.1, arch section, 2.2, straight line portion, the 3, second otch, 4, moving contact installation portion, 5, promote contact site, 6, moving contact, 7, lead-out tablet, 8, push rod.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
The movable contact spring of invention relay, it comprises body 1, and body 1 offers the first otch 2 and the second otch 3, and the part between the first otch 2 and the second otch 3 of body 1 is moving contact installation portion 4.
First otch 2 is sequentially formed by connecting by arch section 2.1 and straight line portion 2.2; Second otch 3 is linear incision.
The straight line portion 2.2 of the first otch 2 and the second otch 3 are parallel to each other.
Described straight line portion 2.2 and the second otch 3 are angular cut.
The angle of inclination of angular cut is 45 degree, and angle of inclination also can be 30 degree, 40 degree, 50 degree, 55 degree etc.
In order to the movable contact spring of easy understand invention relay, all increase to be decorated with in moving contact 6 and lead-out tablet 7, Fig. 3 in Fig. 2 and Fig. 3 and be also decorated with push rod 8, push rod 8 is connected with promotion contact site 5, for diagram is clear, in Fig. 3, arch section 2.1 and straight line portion 2.2 are not made marks.
Claims (2)
1. the movable contact spring of a relay, it comprises body (1), it is characterized in that, body (1) offers the first otch (2) and the second otch (3), first otch (2) is sequentially formed by connecting by arch section (2.1) and straight line portion (2.2), the first half of described first otch (2) is arch section (2.1), the latter half is straight line portion (2.2), and the second otch (3) is linear incision; Straight line portion (2.2) and second otch (3) of the first otch (2) are parallel to each other; Straight line portion (2.2) and second otch (3) of described first otch (2) are angular cut, the part be positioned between the first otch (2) and the second otch (3) of body (1) is moving contact installation portion (4), thus makes anti-contact cementability good.
2. the movable contact spring of relay according to claim 1, is characterized in that, the angle of inclination of angular cut is 45 degree.
