The utility model discloses an improvement to the movable contact spring structure for movable contact spring non -deformable, the mechanical strength of movable contact spring obtains better promotion than prior art's movable contact spring, can solve betterly and warp the assembly quality problem that arouses and the electrical contact performance problem of product because of prior art's movable contact spring is easy.
Description
Technical field
The utility model relates to a kind of sealed relay, particularly relates to the movable contact spring that a kind of TO-5 type sealed relay is used.
Background technology
The movable contact spring that the TO-5 type sealed relay of prior art is used is that cross section is 0.1 × 0.7mm2The square-section of size,Movable contact spring is assemblied between the thread normally closed stationary contact and Chang Kai stationary contact being parallel to each other. (also in theory) in the ideal situation,Movable contact spring should be line with the contact form of stationary contact and contacts, and when the action of TO-5 type sealed relay, contact conversion is reliable. AndUnder actual conditions, thread often open/normally closed stationary contact can be accomplished to be parallel to each other, but movable contact spring part is due to current fresh water (FW)Equality reason, bad mechanical strength, is easy to produce distortion, is difficult to accomplish that movable contact spring and stationary contact become line to contact shape in production processState, this just causes the electrical contact performance of relay poor. The movable contact spring of using due to the TO-5 type sealed relay of prior art is out of shapeSeriously, assembly quality and assembly qualified rate have also been restricted.
The technological level restriction of the movable contact spring of using due to the TO-5 type sealed relay of prior art, causes relay to try in the life-spanTest in process and often occur that dynamic circuit connector is bonding, the transient fault of quiet make and break.
Utility model content
The purpose of this utility model is to overcome the deficiency of prior art, the moving spring that provides a kind of TO-5 type sealed relay to useSheet, by the improvement to movable contact spring structure, makes movable contact spring not yielding, and the mechanical strength of movable contact spring is than the moving spring of prior artSheet is promoted preferably, can solve preferably the easily caused assembly quality problem of distortion of movable contact spring because of prior artElectrical contact performance problem with product.
The utility model solves the technical scheme that its technical problem adopts: the moving spring that a kind of TO-5 type sealed relay is usedSheet, comprises movable contact spring body, the upper arc line shaped shape that is made as respectively below middle part protrusion of the cross section of described movable contact spring body.
The dual-side of the cross section of described movable contact spring body is made as respectively linear shape.
The dual-side of the cross section of described movable contact spring body is made as respectively arc line shaped shape.
The upper of the cross section of described movable contact spring body is symmetrical below.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is owing to having adopted the upper arc line shaped shape that is made as respectively below middle part protrusion of the cross section of movable contact spring bodyShape, makes movable contact spring not yielding, and mechanical strength gets a promotion than the movable contact spring of square-section, movable contact spring and two stationary contactsContact form is some contact, and contact contact is larger, is easy to reach designing requirement in assembling process, assembly quality, qualifiedRate is increased dramatically, and the electrical contact performance of product is also well improved. Can solve well TO-5 micro sealing continuesThe dynamic circuit connector often occurring in unstable, the life test process of contact resistance producing because of movable contact spring reason that electrical equipment exists is bonding, quietThe problems such as the transient fault of make and break.
Below in conjunction with drawings and Examples, the utility model is described in further detail; But a kind of TO-5 type of the present utility modelThe movable contact spring that sealed relay is used is not limited to embodiment.

Detailed description of the invention
Embodiment
Referring to shown in Fig. 1 to Fig. 3, the movable contact spring that a kind of TO-5 type sealed relay of the present utility model is used, comprises movable contact springBody 1, the upper arc line shaped shape that protrude at middle part, the i.e. top 11 of being made as respectively below of the cross section of described movable contact spring body 1Be made as the arc line shaped shape that protrude at middle part, following 12 are also made as the arc line shaped shape that protrude at middle part; TO-5 type sealed relay connectsTouch part assembly and comprise connecting rod 2.
In the present embodiment, the dual-side of the cross section of movable contact spring body is made as respectively linear shape. Certainly, can be also byThe dual-side of the cross section of movable contact spring body is made as respectively arc line shaped shape.
The upper and lower limit of the cross section of described movable contact spring body is symmetrically, and top 11 and following 12 is symmetrical protrusion.
Referring to shown in Fig. 4 to Fig. 6, the movable contact spring that a kind of TO-5 type sealed relay of the present utility model is used, this movable contact spring 1To use in square TO-5 type sealed relay contact portion assembly, this square TO-5 type sealed relay contact site groupingPart also comprises square base 3, normally closed stationary contact 21 and Chang Kai stationary contact 22.
Movable contact spring 1 and the contact form of stationary contact 21,22 are and contact.
Referring to shown in Fig. 7 to Fig. 9, the movable contact spring that a kind of TO-5 type sealed relay of the present utility model is used, this movable contact spring 1To use in circular TO-5 type sealed relay contact portion assembly, the grouping of this circle TO-5 type sealed relay contact sitePart also comprises round base 4, normally closed stationary contact 23 and Chang Kai stationary contact 24.
