A kind of motor wire lid
Technical field
The utility model relates to a kind of motor wire lid, and this motor wire lid comprises line outlet, and this line outlet is used to be provided with the connecting line that is connected to the motor binding post.
Background technology
At present, known motor wire lid is varied, mainly can divide three kinds by function: 1. simple and easy line lid, and its effect mainly is to hide the motor line outlet, prevents that foreign material from entering motor inside, function and simple in structure is cheap; 2. dustproof supplementary protection motor connecting line solder joint function simultaneously, common being mainly is welded on connecting line on the motor PCB, utilize dust cap fixing motor outlet direction and PCB, make and firmly pull when drawing motor leads because of not direct stressed being protected of the solder joint of fragility, be not easy to disconnect or come off, this functional line lid complex structure is produced and the use complex process, and cost is higher; 3. use puncture type terminal formula structure line lid, this mode can make fixedly becoming easily of motor connecting line and simple, but the line lid is produced very complicated.
The utility model content
Technical problem to be solved in the utility model is that the structure of motor wire lid is improved, and make the motor wire lid possess dust reduction capability and protection motor bonding wire function simultaneously, and its manufacturing process is simple.
In order to solve the technical problem, the line outlet of motor wire lid of the present utility model is a cable clamping interface, and this cable clamping interface has a wire blocking port and line accommodation section, and the Breadth Maximum of line accommodation section is less than the external diameter of connecting line, and connecting line snaps in the line accommodation section from wire blocking port.
Because the line outlet of motor wire lid is a cable clamping interface, after connecting line is welded to the binding post of motor, tie line is snapped in the cable clamping interface of motor wire lid, utilize the distortion of the insulating barrier of connecting line to make tie line and cable clamping interface tight fit, thereby when firmly pullling lead, because of lead is fixed by the line lid, its strength all is transmitted to the motor wire lid, so pad and motor binding post do not stress, and are subjected to effective protection, this motor wire lid also has the dustproof function certainly; Owing to only cable clamping interface need be set and cover in motor wire, this line lid simple shape, the card line is convenient, can reduce auxiliary fixing cord material such as PCB and reduce corresponding welding procedure.
Description of drawings
Fig. 1 is the schematic diagram of an embodiment of motor wire lid of the present utility model;
Fig. 2 is the schematic diagram of variation example of the embodiment of motor wire lid of the present utility model shown in Figure 1;
Fig. 3 is that another of embodiment of motor wire lid of the present utility model shown in Figure 1 changes the schematic diagram of example.
Embodiment
As shown in Figure 1, in one embodiment, motor wire lid of the present utility model has a plurality of cable clamping interfaces 100, and cable clamping interface 100 has a wire blocking port 110 and line accommodation section 112, is formed with a pair of relative anticreep barb 114 between wire blocking port 100 and line accommodation section 112.Connecting line enters line accommodation section 112 from wire blocking port 100 under the effect of external force, the Breadth Maximum of line accommodation section 112 is less than the external diameter of connecting line (not shown), so the insulated wire skin of the connecting line in the online accommodation section 112 is extruded into the shape of line accommodation section 112, the distortion of the insulated wire skin by connecting line makes connecting line and line accommodation section 112 tight fits, when external force pulling connecting line, external force can be passed to the motor wire lid and can not be passed to the binding post that connecting line connects.Anticreep barb 114 is formed between wire blocking port 110 and the line accommodation section 112, is difficult for withdrawing from after making connecting line snap in line accommodation section 112.As shown in Figure 1, the width of a plurality of cable clamping interfaces 100 and length can be inconsistent.
In variation example shown in Figure 2, cable clamping interface 200 only is provided with an anticreep barb 214, and cable clamping interface 200 is in the layout and the non-uniform Distribution of motor wire lid, so that the turnover of connecting line.
In another variation example shown in Figure 3, cable clamping interface 300 only comprises line accommodation section 312 and wire blocking port 310, and the width of wire blocking port and line accommodation section is roughly the same.
By above-mentioned description; be understood that; as long as cable clamping interface of the present utility model has wire blocking port and the line accommodation section can solve technical problem described in the utility model; so protection range of the present utility model should not be subjected to the restriction of above-mentioned execution mode, protection range of the present utility model is as the criterion when looking accompanying the scope that the application's claim defined.
