Description
Technical field
The present invention relates to electronic equipment locking technology, particularly a kind of locking strip.
Background technology
Pcb board or module in electronic equipment are fixed in cabinet or subrack the general mode using locking strip, locking strip
Pcb board or module can be made to be fastened in cabinet, there is good shock strength.
Existing locking strip generally stay bolt runs through some wedges, by rotating stay bolt, makes wedge and main body
Between change relative position by inclined-plane so that it is whole height increase, reach locking purpose.But existing locking strip has following lacking
Falling into: during locking strip right angle setting, be affected by gravity, each wedge activity, to its extreme position, needs to adjust position, impact assembling
Efficiency；Locking strip each several part when non-tight condition, each several part all can relative movement, each wedge height is inconsistent, and module exists
Insert in the installation process of cabinet and have touch block phenomenon, be not easy to module assembling, need the position of each wedge of manual setting, in order to avoid
Indivedual wedge impact assemblings；Pcb board or module typically require through cabinet heat conduction, use tradition locking strip, can only by with
The inclined-plane of the wedge both sides of device contacts conducts heat with the contact of incline plane of adjacent wedge both sides, then by heat by with machine
The wedge bottom surface of case contact reaches cabinet, and width only about the 0.8mm on inclined-plane, wedge both sides, heat-transfer capability is limited.
Chinese patent literature CN 1047913737A discloses a kind of right angle setting locking strip, and this locking strip includes mutually
The wedge shape connected is fixed groove, clamping wedge, wedge head screw rod, is rotated voussoir and tension reed.By fixing groove and clamping in wedge shape
Access Division is set between wedge, utilizes socket tension reed to realize mutual traction balance between each assembly, when making right angle setting not
Board can be affected insert.But this locking strip structure is complicated, use reed structure, locking strip reliability to can not get ensureing simultaneously, logical
Crossing clamping wedge side and bottom surface heat conduction, contact area is too small.
Chinese patent literature CN 104747637A discloses a kind of novel reed locking strip, and this locking strip includes integral type
Spring clip gripping member, install the anti-nut that turns in Spring clip gripping member one end, and turn over nut even through Spring clip gripping member and with anti-
The regulation bolt connect.The elastic force utilizing elastic clamping pieces realizes the clamping of board, it is ensured that electric conductivity reliably, and can prevent lock
Tight bar upset, reduces plug-in effect.Adopting the structure, pcb board or module are too small with cabinet contact portion, it is impossible to meet heat conduction
Requirement, the intensity of reed structure is difficult to meet requirement simultaneously.
Summary of the invention
It is an object of the invention to provide a kind of good heat conduction effect, can right angle setting, processing technology is simple and the lock of anticreep
Tight bar.
For achieving the above object, the present invention uses following technical solution:
A kind of locking strip, including base, pushing ram, wedge, contiguous block, screw rod and pin；
Described base includes that base body, the boss being positioned at base body one end and some wedge shapes are protruding, described wedge shape
Bulge clearance is arranged in base body, the protruding pushing ram locating slot that has along base length direction of each wedge shape, different wedge shapes
Protruding pushing ram locating slot is located along the same line；Described pushing ram locating slot includes top cavity and the bottom connected up and down
Cavity, top cavity upper opening, lower section connects with bottom cavity, and bottom cavity is at the width being perpendicular on base length direction
More than top cavity width；
Described pushing ram includes pushing ram main body, location edge, advances buckle, pin via；Described propelling buckle and pin
The quantity that the quantity of nail via is protruding with wedge shape is identical, advances buckle and pin via to be disposed in pushing ram main body, institute
State location edge to be positioned at below pushing ram main body, and width is more than pushing ram body width；
The quantity of described wedge is identical with the quantity of wedge shape projection, and each wedge includes pin installing hole, locator card
Groove and snap-fit grooves；
Described pushing ram inserts pushing ram locating slot from base without boss side, described pushing ram main body and location edge
In the corresponding top cavity inserting pushing ram locating slot and bottom cavity, the snap-fit grooves of wedge matches with location edge,
Locating groove matches with advancing buckle and pushing ram main body；Wedge is arranged on pushing ram by pin, and passes through pin
Length control wedge displacement height；Screw rod pass boss, be arranged on the side of contiguous block, the opposite side of contiguous block with push away
Enter bar to connect；During locking, screw rod promotes pushing ram to move along pushing ram locating slot, and wedge upwards produces on the inclined-plane that wedge shape is protruding
Raw displacement.
Compared with prior art, useful technique effect is the present invention: (1) present invention uses pin by wedge and propelling
Bar is fixed, and each wedge position is the most stable, without adjusting during installation, it is to avoid plug-in effect；(2) pushing card fastener has trace to become
Shape amount, it is ensured that after fastening, all wedge bottom surfaces are concordant；(3) wedge of the present invention is big with base contacts area, owns simultaneously
All contacting with cabinet under wedge tightening state, bottom surface is at the same time as heat-conducting planar, and heat-conducting effect is more preferable.
