Abstract
The invention discloses a contactor coil framework. The contactor coil framework comprises a tubular winding part, an upper baffle and a lower baffle, wherein the tubular winding part is provided with a central through hole. A buffering part is integrally formed at the lower end of the lower baffle, and a buffer space is formed between the buffering part and the lower baffle so that external force which the buffering part is subject to can be released through the buffer space. The invention further discloses a drawer type contactor. The drawer type contactor comprises a base with an assembling cavity and the coil framework installed in the assembling cavity. When the contactor coil framework is in assembly, prior to the lower end face of the lower baffle, the pressed surface of the buffering part abuts against the withstanding surface in the assembling cavity. The suspended buffering part has a certain elasticity and can have buffering protecting effect; buffering components do not need to be assembled on the drawer type contactor with the coil framework, assembly processes are reduced, workload is reduced, and working efficiency is effectively improved.
Description
Technical field
The present invention relates to a kind of contactor coil frame and there is its drawer type contactor, belong to contactor construction design field.
Background technology
Drawer type contactor has the advantages such as easy to maintenance, drawer type contactor will be realized drawer function, guarantee that drawer advances, pulls out flexibility and reliability, magnetic circuit system (comprise coil rack, be wound on the solenoid on coil rack and be arranged on the iron core on described coil rack) must be fixed on pedestal, thereby realize the trimming function of magnetic system.
In existing drawer type contactor, coil rack does not possess pooling feature, need between coil rack and pedestal, assemble buffer unit to realize pooling feature when mounted, described buffer unit is generally rubber blanket or spring, when assembling drawer type contactor, to first buffer unit be installed on the coil rack of pedestal or magnetic circuit system, then magnetic circuit system is fixed on pedestal, due in assembling process, increased the assembly process of buffer unit, this just makes assembly work amount strengthen, and further causes operating efficiency to reduce.
Summary of the invention
To this, technical problem to be solved by this invention is that existing contactor coil frame is not because possessing pooling feature, cause magnetic circuit system to need when mounted to realize pooling feature by assembling buffer unit, and then cause workload to increase, the problem that production efficiency reduces, thereby provide a kind of pooling feature that possesses, when mounted without refilling the contactor coil frame of joining buffer unit and the drawer type contactor with this coil rack.
The technical scheme that realizes the object of the invention is:
A contactor coil frame, comprise be provided with central through hole tubulose winding section, take shape in the overhead gage of upper end, described tubulose winding section and take shape in the lower baffle plate of lower end, described tubulose winding section; The lower end of described lower baffle plate is one-body molded unsettled buffer part, is formed with cushion space, so that the external force that described buffer part is subject to is discharged by described cushion space between described buffer part and described lower baffle plate.
In technique scheme, on central through hole axis direction, the compression face of described buffer part protrudes from the lower surface of described lower baffle plate.
In technique scheme, the compression face that the width scales of described cushion space on central through hole axis direction is more than or equal to equidirectional the above buffer part protrudes from the height dimension of the lower surface of described lower baffle plate.
In technique scheme, the height dimension that the compression face of described buffer part protrudes from the lower surface of described lower baffle plate is 0.4mm to 0.6mm.
In technique scheme, on described lower baffle plate, form two centrosymmetric buffer part in the axis about described central through hole.
In technique scheme, on described coil rack, form the fixed structure being fixed on pedestal.
In technique scheme, the described fixed structure elastic hook on described lower baffle plate that is formed in one.
In technique scheme, on described lower baffle plate, form two centrosymmetric elastic hooks in the axis about described central through hole.
In technique scheme, described elastic hook is along described central through hole axis towards extending away from described lower baffle plate direction.
In technique scheme, on described cushion space, offer the crossed beam trunking passing for wire.
A drawer type contactor, comprises and has the pedestal of assembly cavity and be arranged on the coil rack in described assembly cavity, described coil rack is coil rack recited above; When assembling, the compression face of described buffer part is inconsistent prior to lower surface and the face of keeping out in described assembly cavity of described lower baffle plate.
The present invention has positive effect:
(1) in the present invention, one-body molded on the lower baffle plate of described coil rack have a buffer part, and unsettled buffer part has certain resilience, and the external force being subject to is (when vibrations, impulsive force from pedestal) by cushion space, discharged, thereby can be played cushioning effect; Adopt the magnetic circuit system of coil rack of the present invention after packing the assembly cavity of pedestal into, described buffer part compressive deformation also offsets with the blocking surface of described pedestal, and the lower surface of described lower baffle plate and the blocking surface of described pedestal offset; When drawer type contactor shakes, buffer part absorbs the collision energy of magnetic circuit system and pedestal by there is deformation, avoid magnetic circuit system and described pedestal generation sharp impacts; Owing to can realizing pooling feature by described buffer part, therefore, without assembling in addition buffer unit, reduced assembly process, workload reduces, and has effectively improved operating efficiency.
(2) in the present invention, the elastic hook that the fixed structure of fixed installation coil rack is formed in one on described lower baffle plate, when assembling, elastic hook articulates and coordinates and coil rack can be fixed with pedestal, and designs simplification is with low cost.
(3) in the present invention, described elastic hook is along described central through hole axis towards extending away from described lower baffle plate direction, be the bearing of trend of described elastic hook while packing pedestal assembly cavity into described coil rack cartridge insertion direction consistent, so, described coil rack just can make connecting and fixing of described elastic hook and pedestal when packing assembly cavity into, and this just makes the installation of coil rack more convenient.
(4) in the present invention, offer the crossed beam trunking passing for wire on described cushion space, by adopting this structure, the lead-in wire that is wound on the solenoid on coil rack can be from cushion space cabling, and without establishing cable tray in addition, structure is more reasonable.
