Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a camera structure which is applied to a rear confirmation camera for a vehicle and is attached to the outside, and more particularly to a camera structure having an improved waterproof structure.

[0002]

[Prior art]

 In the conventional camera structure of this type, as shown in FIG. 4, the camera body 30 is housed in a case 31, and the front cover 33 is provided at the front end of the case 31 via a rubber packing 32. A screw 38 inserted through the screw insertion holes 34 on the left and right sides of the front cover 33 is inserted through the screw through hole 32a of the packing 32 and screwed into the screw hole 31a formed on the end surface of the case 31. The front cover 33 is attached to the case 31, and the rear cover 36 is provided along the rear end of the case 31 via the rubber packing 35, and the rear cover 36 is inserted into the left and right screw insertion holes 37. The inserted screw 39 penetrates the screw through hole 35a of the packing 35 and is screwed into the screw hole 31b formed on the end surface of the case 31, whereby the rear cover 36 is attached to the case 31. It is mounted. Then, the packings 32 and 35 are compressed at the front and rear ends of the case 1 by tightening the screws 38 and 39, thereby achieving a waterproof function.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional camera structure, since the packings 32 and 35 have a uniform thickness, the packings 32 and 35 are fastened at the front and rear ends of the case 1 by tightening the screws 38 and 39. When compressed, as shown in FIG. 5, the peripheral portions of the screw through holes 32a and 35a of the packings 32 and 35 protrude, and there is a problem that waterproofness is lost.

The present invention has been made in view of the above problems, and its purpose is not only to make waterproofing perfect but also to determine the setting position of packing. An object of the present invention is to provide a camera structure that is easy and can be easily assembled.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention forms recesses in a mounting member to which a cover is mounted via packings, forms screw holes in the bottoms of these recesses, and forms the packings in the packings. A protrusion is formed around the screw insertion hole, the packing is placed along the mounting member, and the protrusion of this packing is fitted into the recess of the mounting member. It is characterized by being fastened to the mounting member with a screw. Further, it is preferable that the mounting member is a boss provided on the camera body housed in the case.

[0006]

[Action]

 With this configuration, the convex portion of the packing is fitted in the concave portion of the mounting member, and the convex portion prevents outward deformation by the concave portion. When pressure is applied to the packing, the convex portion is deformed inward, and the waterproofing between the screw portion, that is, the mounting member and the packing can be completed. Further, since the convex portion of the packing is fitted into the concave portion of the mounting member, the packing is prevented from being displaced or protruding, and the convex portion of the packing is fitted into the concave portion of the mounting member at the time of assembly. If they are matched, the packing setting position is determined, and the assemblability is improved.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a camera structure according to the present invention in an exploded state, FIG. 2 is a longitudinal sectional view of the camera body, and FIG. 3 is an enlarged view of a portion A of FIG.

As shown in FIG. 1, the camera structure according to the present invention includes a case 1, a camera body 2 housed in the case 1, a front cover 3 located at a front end of the case 1, and a rear case. A rear cover 4 located at an end portion, a rubber packing 16 interposed between the front cover 3 and the case 1, and a rubber packing 18 interposed between the rear cover 4 and the case 1 are provided. There is.

The camera body 2 is equipped with a lens unit 5 which is an image reading apparatus using a solid-state image pickup device such as a CCD device, an iris motor 6, an iris cover 7, a lens holder 8 and electronic parts such as a CCD device. Also provided is a first substrate 9 and a second substrate 10 to which connectors, sockets and the like are attached. A boss 11 as a mounting member is fixed to the left and right of the front end of the lens holder 8 of the camera body 2, and a boss 12 as a mounting member is fixed to the left and right of the rear end of the lens holder 8. There is. Recesses 11a and 12a are formed on the end faces of the respective bosses 11 and 12, and screw holes 11b and 12b are formed on the bottoms of these recesses 11a and 12a.

The case 1 is a tubular body having front and rear end faces opened, and is an extrusion molded product. The front cover 3 is provided with a window 13 and screw insertions located on the left and right sides sandwiching the window 13. The rear cover 4 has a cord lead-out hole (not shown) and left and right screw insertion holes 15.

Further, screw through holes 22 are formed on the left and right sides of the packings 16 and 18, and convex portions 23 are formed on the inner side surfaces of the packings 16 and 18 so as to surround the screw through holes 22. There is.

The camera body 2 is housed in the case 1, and the front cover 3 extends along the front end of the case 1 via the packing 16. The front cover 3 is attached to the camera body 2 by screwing the screws 17 inserted into the left and right screw insertion holes 14 through the screw through holes 22 of the packing 16 and screwing them into the screw holes 11b of the boss 11. In this case, the convex portion 23 of the packing 16 is fitted in the concave portion 11a of the end surface of the boss 11 to prevent the packing 16 from being displaced or protruding.

Further, the rear cover 4 is provided along the rear end of the case 1 via the packing 18, and the screws 19 inserted into the left and right screw insertion holes 15 of the rear cover 4 are attached to the packing 18. The rear cover 4 is attached to the camera body 2 by penetrating the screw through hole 22 and screwing it into the screw hole 12b of the boss 12. In this case, the convex portion 23 of the packing 18 is fitted in the concave portion 12a of the end surface of the boss 12 to prevent the packing 18 from being displaced or protruding. The cord 20 connected to the second substrate 10 is led out from the cord lead-out hole of the rear cover 4, and the connector 21 is connected to the end of the cord 20.

As described above, the front cover 3 and the rear cover 4 are fastened to the bosses 11 and 12 at the front and rear ends of the camera body 2 by the screws 17 and 19, and the packing is made by the front cover 3 and the rear cover 4. Since the case 1 is sandwiched by the screws 16 and 18, the packings 16 and 18 are compressed at the front and rear ends of the case 1 by tightening the screws 17 and 19 to satisfy the waterproof function. Has been done.

Further, the convex portions 23 of the packings 16 and 18 are fitted into the concave portions 11a and 12a of the end faces of the bosses 11 and 12, and the convex portions 23 are prevented from being deformed outward by the concave portions 11a and 12a. Therefore, when pressure is applied to the packings 16 and 18 through the front cover 3 and the rear cover 4 by tightening the screws 17 and 19, the convex portion 23 is deformed inward, and the screws 17 and 19 are That is, the waterproof between the bosses 11 and 12 and the packings 16 and 18 is perfected. Further, since the convex portions 23 of the packings 16 and 18 are fitted into the concave portions 11a and 12a of the end surfaces of the bosses 11 and 12, the packings 16 and 18 are prevented from being displaced or protruding, and at the time of assembling. If the convex portions 23 of the packings 16 and 18 are fitted into the concave portions 11a and 12a of the end faces of the bosses 11 and 12, the set positions of the packings 16 and 18 are determined, and the assembling property is improved.
