Embodiment
Interface protection structure in the utility model can be applicable to the interface of various electronic equipments, for example, and mobile phone, camera etc.As shown in Figure 5, this interface protection structure comprises interface spliced eye 101, interface plug connecting hole 102 and the interface plug 200 that is positioned on the shell 100.Corresponding data input/output interface (not shown) promptly exposes from spliced eye 101.Interface plug connecting hole 102 is arranged on a side of spliced eye 101, is used for connecting interface plug 200.At the opposite side of spliced eye 101, be provided with bayonet socket 103.
As shown in Figure 3 and Figure 4, interface plug 200 comprises main body 201, and these main body 201 rectangular tabulars are made by plastic material, for example engineering plastics (PC), modified polystyrene plastic (ABS).On the inner surface of main body 201, be provided with jam 202.This jam 202 comprises lead portion 202a, the stop portion 202b of front end, cylindrical coupling part 202c and the anti-rotation part 202d that is connected with main body 201 successively.This jam 202 is made by elastomeric material, and for example certain deformation can take place thermoplastic polyurethane (TPU).Jam 202 can be integrated by extra quality Shooting Technique and main body 201.
Lead portion 202a is convenient to install usefulness, and its size is less than the size of interface plug connecting hole 102.During installation it is passed the interface plug connecting hole 102 on the shell 100 earlier, afterwards in the shell 100 pulling it, can make stop portion 202b by interface plug connecting hole 102.After installing, lead portion 202a can be cut off.With reference to Fig. 6, stop portion 202b is a truncated cone-shaped, or truncated cone-shaped as shown in the figure and columniform combination, and the diameter of its close main body 201 1 end is a bit larger tham the diameter of interface plug connecting hole 102, and the diameter of an end that is connected with lead portion 202a is slightly little.By the guide effect of truncated cone-shaped and the extruding of interface plug connecting hole 102, stop portion 202b distortion and by interface plug connecting hole 102.But when oppositely spurring, stop portion 202b can not deviate from from interface plug connecting hole 102.Refer again to Fig. 5, in order to strengthen guiding and limit effect, interface plug connecting hole 102 can be arranged to taper.Its outer end diameter equals the maximum gauge of stop portion 202b, and inner diameter is less.
The size of cylindrical coupling part 202c is less than the size of interface plug connecting hole 102, can seesaw in interface plug connecting hole 102 and rotation relatively, makes that whole interface plug 200 is extracted, fastening or rotation.The cross sectional shape of anti-rotation part 202d is non-circular, and in this embodiment, the cross section of anti-rotation part 202d is a rectangle.In illustrated embodiment, the cross sectional shape of anti-rotation part 202d is a rectangle, and its length is greater than the diameter of interface plug connecting hole 102, and width is less than the diameter of interface plug connecting hole 102.Shell 100 is provided with the holddown groove 104 of correspondingly-sized, and this holddown groove 104 runs through from interface plug connecting hole 102, and about the center symmetry of interface plug connecting hole 102.When 200 fastenings of interface plug, anti-rotation part 202d cooperates with holddown groove 104, and interface plug 200 can not arbitrarily be rotated.After extracting interface plug 200, anti-rotation part 202d and holddown groove 104 break away from, and this moment can be with 200 rotations of interface plug.
When needs are connected the interface of this electronic equipment with other equipment, interface plug 200 extracted and Rotate 180 ° after, with 200 fastenings of interface plug.At this moment, anti-rotation part 202d cooperates with holddown groove 104, makes interface plug 200 fixing and can not rotate.Therefore, solved the difficult fixing problem of interface plug in the prior art.
On the inner surface of main body 201, also be provided with and be used for the buckle 203 that cooperates with bayonet socket 103.This buckle 203 is also made by elastomeric material.During 200 fastenings of interface plug, buckle 203 cooperates with bayonet socket 103.When interface plug 200 was extracted, both broke away from.
At the end of anti-rotation part 202d, near 202c place, cylindrical coupling part, be provided with the holding section 202e of projection.The size of this holding section 202e is a bit larger tham the diameter of interface plug connecting hole 102, and when 200 fastenings of interface plug, the holding section 202e crimp under external force of projection is by interface plug connecting hole 102.After holding section 202e was by interface plug connecting hole 102, moment restored to the original state.Because its size is a bit larger tham the diameter of interface plug connecting hole 102, can prevent that therefore interface plug 200 from sliding to stop portion 202b.When extracting interface plug 200, the holding section 202e of projection is out of shape under tension, deviates from from interface plug connecting hole 102.The longitudinal section of the holding section 202e of projection is preferably circular.It can play the effect identical with above-mentioned buckle 203, but simplifies the structure.
On the inner surface of main body 201, between jam 202 and the buckle 203, also be provided with the bossing 204 that cooperates with interface.This bossing 204 is made by elastomeric material, and when interface did not use, bossing 204 inserted interfaces, can play better dustproof effect.
