Detailed description of the invention
Fig. 1 is the status diagram before the component precompressed of contact spring.
Fig. 2 is the status diagram after the component precompressed of contact spring.
Fig. 3 is the status diagram that the quick prepressing device of contact spring of the invention carries out precompressed to contact spring component.
Specific embodiment
In order to make the technical means, creative features, achievement of purpose and effectiveness of the invention easy to understand, below with reference to tool
Body illustrates (Fig. 1, Fig. 2, Fig. 3), is further described.
Referring to Fig. 1 and Fig. 2, contact spring component shown in figure includes guide rod 1, upper contact head spring base 2, pressure spring 3 and lower touching
Head spring base 1A, lower touch spring seat 1A is fixed on guide rod 1, and upper contact head spring base 2 and 3 sets of pressure spring are on guide rod 1, pressure spring 3
Between upper contact head spring base 2 and lower touch spring seat 1A.After precompressed, the cylinder pin hole 11 of guide rod 1 exposes upper contact head spring
Seat 2 passes through cylinder pin hole 11 with a straight pin 4, the downward direction touch spring seat 1A of upper contact head spring base 2 is forced to move, right
Pressure spring 3 carries out precompressed.
Referring to Fig. 3, a kind of contact spring prepressing device shown in figure, including pedestal 24, contact seat support 25, Cam rest
26, cam 22, gib block 23.
Pedestal 24 include a bottom plate 241 and be molded over 241 left and right sides of bottom plate and project upwards left and right side plate 242,
243.Contact seat support 25, Cam rest 26 are fixed on bottom plate 241 along the axis direction interval of pedestal 24.In contact seat support
One is offered on 25 to the card hole 251 for the upper contact head spring base 2 being caught in contact spring component.
Cam 22 is located on Cam rest 26 by straight pin 27 and 28 eccentric shaft of shaft block ring, and shaft block ring 28 is to cylinder
27 axial limiting of pin.Operation handle 21 is provided on cam 22.
The left and right sides of gib block 23 offers left and right guide groove 231,232, left and right guide groove 231,232 respectively with
The upper limb sliding gomphosis of left and right side plate 242,243 enables gib block 23 to move back and forth along left and right side plate 242,243.It is leading
To item 23 middle position aperture and be welded with a pin shaft 29, the cam week face contact of the first end 291 of pin shaft 29 and cam 22,
A guide rod hole is offered in the second end 292 of pin shaft 29.
When carrying out the component precompressed of contact spring, the upper contact head spring base 2 in contact spring component is snapped into contact base first
