Description
Technical field:
The utility model relates to a kind of wire rod fixing device, relates in particular to a kind ofly to be welded on the circuit board, to be used for wire rod fixing device that wire rod is positioned, and has the strip of this device.
Background technology:
On circuit board, add extra wire rod sometimes, for example part power line or data wire etc. influence other assembly for these wire rods are not moved arbitrarily on circuit board, must be fixed by some modes.
For example be used to connect the data wire of microphone, can be bonded on the circuit board with for example adhesive tape in the past.This kind way is not only not attractive in appearance, and when adhesive tape lost viscosity, wire rod can come off; Otherwise if adhesive tape is too sticking, then when changing or dismantle wire rod, the residual glue trace of meeting is stained with sticking dust and foreign material everywhere on circuit board, in use very inconvenience.
Notification number is the Chinese utility model patent of CN2641693, a kind of " wire rod spacer structure " disclosed especially, as shown in Figure 1, this wire rod spacer 10 is used for fixing the wire rod on the motherboard, after wire rod slips into the alcove 101 of spacer by backstop protuberance 105, promptly be positioned in the alcove 101 and and stop, can't from spacer, break away from outward, wire rod fitly is installed on the motherboard by backstop protuberance 105.
Yet the backstop protuberance 105 of above-mentioned wire rod spacer 10 rushes to alcove 101 from this top 104, therefore can form a downward depression at the top 104 of wire rod spacer 10, thereby destroy the smooth of its top 104.Because wire rod spacer 10 mainly is to adopt surface mounting technology (SMT) to be installed on the circuit board, also promptly with the air-breathing generation negative pressure of a suction nozzle, the top 104 of absorption wire rod spacer 10, move wire rod spacer 10 to carry, and behind the predetermined welding position on the alignment circuit plate, be released on the printed circuit board (PCB); The printed circuit board (PCB) that to place all multicompartments again is via the solid welding of reflow machine, and finishes the installation of electronic building brick.So, when the top 104 of wire rod spacer 10 is not a smooth adsorption plane, will cause the absorption difficulty of suction nozzle, even possibility dropping because of assembly in moving on the way, causing to have the position of wire rod spacer 10 blank on the circuit board, increased follow-up check puzzlement, thereby solidus is had problems.More seriously, in case wire rod spacer 10 is being moved dropping of process midway, will cause short circuit in the unexpected appearance in other position of circuit board.
And the construction section 103 of this wire rod spacer 10 is a complete plane, when carrying out solid welding, the influence that may be subjected to fusion scolding tin vacillate phenomenon and off normal, or can't strong fix, make colluded by wire rod to draw or after foreign object collides, may come off when wire rod spacer 10.
Therefore, not only had locating effect but also can fix the stopping part of wire rod, and then can rise to stopping part, and wire rod fixing device more firmly is fixed on the circuit board and had not produced skew by scolding tin if can on the construction section of wire rod fixing device, design one; And after wire rod slips into it and puts space of lines, will be difficult for getting loose by the stopping part block therein.
The utility model content:
Therefore, one of the technical problems to be solved in the utility model is, provide a kind of can not only be firmly, exactly on the soldered circuit board, difficult drop-off, be difficult for producing skew, and be easy to be adsorbed adsorption reliability, the wire rod fixing device that can not drop in the adsorption process.
Another technical problem to be solved in the utility model is that a kind of strip with above-mentioned wire rod fixing device is provided.
The wire rod fixing device that provides according to the utility model, system is for utilizing surface mounting technology to be welded on the circuit board, be used for fixing wire rod, this wire rod fixing device comprises: one has the bottom surface that engages with this circuit board and a construction section in contrast to the end face of this bottom surface, is formed with a stopping part that protrudes to described end face from described bottom surface near an ora terminalis of described construction section; And one from another ora terminalis of described construction section extend away from described construction section bending and match with described construction section define one have an opening put space of lines around section, and describedly have a smooth adsorption section parallel with described construction section around section.
The wire rod fixing device that provides according to the utility model also has following attached technical characterictic:
Described construction section comprises that one is parallel to the body of the solder side on the described circuit board.
Be formed with a spout hole between described body and described stopping part.
