Background technology
Present automobile generally all adopts the contact pin mounting means with a various electronic device, and this mounting means exists bigger potential safety hazard, the risk that exists contact pin to come off to the reliability aspect of automobile product.The contact pin of the product of existing contact pin type mainly is installed on the plastic through the mode of glue or hot pressing, and glue is between often in the use process, and glue exists secondary pollution and weathering easily in the abominable environment for use of automobile; Its adhesion strength can not get guaranteeing; The mode of hot pressing is because it be the connected mode of rigidity in addition, in the environment for use of the height of automobile vibrations, and the risk that exists cracking perhaps to break; So there is certain potential safety hazard in the connected mode of present contact pin; Above-mentioned in addition two kinds of processing modes are had relatively high expectations to operating personnel's, and when adopting recently the employee, the quality of product can not get guaranteeing.
Summary of the invention
To above-mentioned technical problem, the present invention provides a kind of contact pin and basin frame firm and reliable connection, is suitable for the novel special-shaped automobile contact pin signalling device of automobile environment for use.
Realize that technical scheme of the present invention is following:
Novel special-shaped automobile contact pin signalling device, it comprises the basin frame that is used to install the signalling device assembly, the center of described basin frame is provided with the magnetic bowl of signalling device; Be provided with magnet steel in the described magnetic bowl, between magnet steel and magnetic bowl, be formed with annular space, in the space, be provided with voice coil loudspeaker voice coil; The upper end of voice coil loudspeaker voice coil is connected with vibrating diaphragm, is provided with a plurality of senders around the magnetic bowl on the basin frame, and the inward flange of basin frame sinks to being formed with the vibrating diaphragm fixed edge; The edge of described vibrating diaphragm is fixed on the vibrating diaphragm fixed edge of basin frame; It is characterized in that: the lower left of described basin frame is provided with the contact pin fixed block, described contact pin and contact pin fixed block integrated setting, and described contact pin is made up of pad and stitch; Described pad is exposed to the contact pin fixed block, and the link of described voice coil loudspeaker voice coil is connected with pad.
Described contact pin and contact pin fixed block change into type through integrated through injection molding; Adopt the integrated through injection molding type of changing into to improve the bonding strength between contact pin and the contact pin fixed block; The secondary pollution of glue connection and the problem of weathering have been overcome; Can overcome simultaneously the cracking of the fixing existence of hot pressing or the problem of breaking, it can be used in the abominable environment for use of automobile
The middle part of described contact pin fixed block is provided with the seam of stepping down; The contact pin fixed block in the left side of the described seam of stepping down is provided with the through hole that runs through the contact pin fixed block, and the through hole of setting is used to insert the tool of a guiding, can be when voice coil loudspeaker voice coil is installed; The voice coil loudspeaker voice coil lead embeds the pad connection that the seam the inside of stepping down is incorporated contact pin into from the below; When extracting tool, the voice coil loudspeaker voice coil lead can form a flaccid part in the seam the inside of stepping down, and can prevent effectively that the people from causing the voice coil loudspeaker voice coil lead very tight for backguy; Improve the impact resistance between voice coil loudspeaker voice coil lead and the solder joint, also can prevent to spur the connectivity robustness that the voice coil loudspeaker voice coil lead impacts contact pin simultaneously.
In sum; The present invention has improved bonding strength between the two through the connected mode of contact pin and basin frame support is improved, and has overcome the fixing defective of traditional glue fixing and hot pressing; Eliminated the hidden danger that the contact pin signalling device in use exists; The through hole that is arranged simultaneously is convenient to the voice coil loudspeaker voice coil lead is carried out a guiding, is convenient to the voice coil loudspeaker voice coil lead and in the seam of stepping down, forms a flaccid part; Can effectively improve the impact resistance between voice coil loudspeaker voice coil lead and the solder joint, also can prevent to spur the connectivity robustness that the voice coil loudspeaker voice coil lead impacts contact pin.
