Description
Technical field
The present invention discloses a kind of contactor head supporting apparatus, belongs to contactor by International Patent Classification (IPC) (IPC) division
Manufacturing technology field.
Background technique
Currently, contactor generally includes, the body, static contact, contact are supported and moving contact, static contact are mounted on the body, and
Moving contact is mounted on contact and supports that contact support activities are mounted in the body, moves under the action of electromagnet, so that dynamic touching
Head is contacted or is separated with static contact.Contact support is one of key part of contactor, is generally made of thermosetting plastics, under
Portion opens up pinned hole (flat or circle), and common cotter pilotage or round pin couple with armature；Upper part is equipped with window, to be packed into dynamic touching
Head and touch spring.When armature supports band moving contact to do closing motion under electromagnetic attraction effect by contact, closed from contact
From closing moment, the active force that the touch spring being further compressed generates makes contact support to bear pulling force around pinned hole；Work as line
After circle power-off, reset spring and touch spring collective effect make contact disconnect (release), by contact support, contact, pin, armature
The movement parts of composition obtain certain speed, and the shoulder and contactor body baffle for supporting contact generate shock, and contact is supported
Shoulder then bears pressure.If contact supports pinned hole and the design of shoulder structure improper, when contactor is frequently attracted, discharges,
It is easy to appear the failures that contact supports fracture.The probe of contactor spring force value of especially 100A or more is bigger, armature is heavier,
The pinned hole and shoulder stress that contact is supported are also bigger, carry out meticulous, reasonable design with greater need for dependency structure.
In addition, contact is supported in the body (the contactor body of 100A or more is all made of thermosetting plastics and is made) guide groove
Reciprocating motion there is friction, and the wearability of thermosetting material is not generally good enough, needs to consider such as when movement parts quality is larger
What reduces the problem of friction.
Chinese document CN 104576218A discloses a kind of contactor reduction friction buffer structure, in contact support and the body
Bolster is installed on the impingement area of contact, forms elastic buffer face on bolster, however, elastic buffering suface, that is, point of impingement in document
It is proximate near the pinned hole at bolster center, since contact supports that around pinned hole be most easy fracture position, the body and contact
Support, bolster collision are the processes hit repeatedly, and the stress generated when hitting and rebounding release is to contact support
Pinned hole is concentrated, and therefore, although above scheme can reach certain desired effect, but still will appear failure.
Existing contactor, such as the A95-30 of Schneider LC1D115, ABB, the 3RT1054 of Siemens, contact supports exist
Following defect:
1) position that contact is supported and the body is hit all is hardness and the higher thermosetting material of brittleness, and more relatively rigidity is hit
It hits, and material wear ability is slightly weak, is unfavorable for improving contact along mechanical life；
2) contact supports that friction pair in body guide groove is thermosetting material to thermosetting material (ABB, Siemens),
Abrasion is big；Though Schneider is provided with the wear-resisting attachment (square plastic materials and parts) of thermoplastic material, only it is arranged in single side, the back side is not set
It sets, if contactor installed by the upward position of square piece, square piece does not work, and contact supports surface directed downwardly and body
Shell guiding rooved face still belongs to thermosetting material and rubs to thermosetting material (gravity).
3) existing contactor prevents fixed pin from falling off and wearing, and generally requires to design more complicated structure or attachment, with
For Schneider, square piece attachment up to 4.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of contactor head supporting apparatus, by monoblock type block piece,
It is primary to clamp, while having the function of positioning, buffer crashworthiness, is three kinds wear-resisting.
In order to achieve the above objectives, the present invention is achieved by the following technical solutions:
A kind of contactor head supporting apparatus, including contact are supported, which is provided with the pin hole of connection armature, and contact supports tool
There is the shoulder hit with the body, shoulder upper surface is striking face, and shoulder side is installed monoblock type block piece and extended to shoulder both ends,
The buffer part of monoblock type block piece is formed in the striking face of shoulder, the pin hole that the buffer part is supported far from contact.

Hole cooperation, which is clamped, supports transverse groove in contact to position capping and develop horizontal portion, company.
Further, the buffer part of the monoblock type block piece is button corner structure, and the bottom surface for detaining corner structure, which is equipped with, to be snapped fitted to
Contact is supported in corresponding pit to fix block piece both ends.
Further, the monoblock type block piece is the integrally formed two-way block piece of hot thermoplastic material, has buffer part thereon
And the friction portion of vertical direction, with block piece center symmetric setting, monoblock type block piece is fixed on for the buffer part and friction portion
Contact supports on the installation position of two sides that the bidirectional integral of monoblock type block piece designs, and is conducive to whole impact resistant capability, and rubs
Position-limiting action plays for buffer part in wiping portion and connected perpendicular portion, company.
Further, the contact support is coupled with armature by fixed pin and the pin hole of cooperation, the transverse groove that contact is supported
The pin hole supported with contact is connected to.
The present invention is supported by contact and the Combination Design of monoblock type block piece, and it is heat-resisting can to give full play to the support of thermosetting property contact
Good, thermoplasticity block piece self-lubricating, good toughness, buffering collision of closed, the comprehensive advantage for reducing abrasion, improve the performance of contactor, make
The selection of contactor installation direction is more, and possesses longer mechanical life.
It is specific as follows that contact of the present invention supports that the cooperation with monoblock type block piece can reduce abrasion: monoblock type block piece of the present invention
Friction portion is a local position, forms thermoplastic material to the friction pair of thermosetting material with body guiding rooved face, is one innings
Portion's point friction, greatly reduces contact area compared with the friction of the integral face of the prior art, reduces the excellent of abrasion to have
Gesture.
