Description

Technical Field

[0001] The present invention relates to a back case for a vehicle-mounted camera and a case for a vehicle-mounted camera, which are provided with a connector module and the like. Background Art

[0002] The vehicle camera case is usually formed by joining a front case on the front side and a rear case on the back side, and houses the vehicle camera and electrically connects an external connector to the vehicle camera substrate via a connector module etc. provided in the vehicle camera case. In the vehicle camera case provided with such a connector module, a structure in which the vehicle camera case and the connector module are fixedly connected is known.

[0003] Specifically, as a technology having such a structure, there is known an electronic device module, comprising: a metal shell (a shell for a vehicle-mounted camera) formed with at least one protrusion; an electronic device unit housed inside the shell; an external device connection connector terminal electrically connected to the electronic device unit and used for connecting to an external device; and a metal grounded shell (connector module) that is arranged in a manner surrounding the external device connection connector terminal and has a surface covered with a metal coating layer and is formed with at least one protrusion insertion portion corresponding to the at least one protrusion of the shell (for example, refer to patent document 1).

[0004] In the electronic device module disclosed in Patent Document 1, for example, a shell (shell for a vehicle-mounted camera) and a ground shell (connector module) are fixedly connected by heating and melting a protrusion head exposed from the surface of a ground shell by laser irradiation so that it is welded to a covering layer located around the protrusion insertion portion.

[0007] Patent Document 1: Japanese Patent No. 6039514 Summary of the invention

[0008] Problems to be solved by the invention

[0009] However, the ground shell (connector module) is generally not only made of metal materials, but also includes components such as resin with weak heat resistance around it. In fact, in the example of Patent Document 1, the internal housing 20 provided around the ground shell 18 is made of resin, and the waterproof component 29 is made of rubber. In such a structure, when the protrusion of the shell is welded to the coating layer of the ground shell, there is a possibility that the components such as the ground shell 18 and the internal housing 20 with weak heat resistance are deformed and damaged. As a result, inferior products are produced with a certain frequency.

[0010] The present invention is a solution proposed to solve such a problem, and its purpose is to provide a vehicle camera housing or a vehicle camera back housing, which can ensure the structural strength of the vehicle camera housing or the vehicle camera back housing and suppress the frequency of inferior products during manufacturing.

[0011] Solutions to Solve Problems

[0012] In order to achieve the above-mentioned object, the back cover for a vehicle-mounted camera of the present invention is characterized by comprising:

[0013] A box-shaped rear shell body, which is joined to the front shell in a manner opposing to form a space for accommodating the vehicle-mounted camera, is formed with an insertion hole and is open on one side; a connector module, which is inserted into the above-mentioned insertion hole, engages with the above-mentioned rear shell body, and at least a portion of which protrudes to the outside of the above-mentioned rear shell body is made of resin; and a shell body, which engages with the above-mentioned connector module and accommodates the above-mentioned connector module, the above-mentioned rear shell body comprising: a rear shell upper surface, which is opposite to the above-mentioned front shell; a plurality of rear shell side surfaces, which are vertically arranged along the outer periphery of the above-mentioned rear shell upper surface; a raised component, which protrudes in a vertical direction from the above-mentioned rear shell upper surface toward the inner surface side of the above-mentioned rear shell body, and is arranged on the surface of the above-mentioned inner surface side of the above-mentioned rear shell upper surface engaged with the above-mentioned connector module; and a fastening receiving portion, which is arranged on the surface of the above-mentioned rear shell upper surface on the outer surface side of the above-mentioned rear shell body and on the surface of the above-mentioned fastening receiving portion The protruding member is fastened by applying pressure without heating in a state where the protruding member is engaged with the connector module. The connector module comprises: a shell as a conductor, which is made of metal and has a cylindrical portion; a terminal, which is arranged on the inner side of the shell along the central axis and can be conducted from one end side to the other end side; and an insulating insulator, which is interposed between the shell and the terminal to hold the terminal. The shell also comprises a flat flange portion, which is formed with a plurality of engaging holes, which are respectively engaged with the rear shell body and the shell body. When the flange portion is engaged with the protruding member of the rear shell body, the protruding member passes through the plurality of engaging holes. The rear shell body is provided with a flange receiving surface as a recessed portion for receiving the flange portion on the surface on the inner surface side of the upper surface of the rear shell, and the protruding member is provided on the flange receiving surface.

[0014] With this structure, when the connector module is fixedly connected to the rear shell body of the vehicle-mounted camera of the present invention, heat is not generated by welding, but the protrusion member protruding in the vertical direction toward the inner surface side on the upper surface of the rear shell body of the rear shell is fastened in a state of engagement with the connector module. Since the fixed connection by fastening is not accompanied by heat generation, even if a part of the connector module is made of resin, the resin part will not be deformed or damaged by heat. Therefore, the frequency of inferior products produced during the manufacture of the rear shell for vehicle-mounted cameras can be suppressed.

[0015] In addition, the method of using fastening is a method of applying pressure to the upper surface of the rear shell provided with the protruding member, but the rear shell for the vehicle-mounted camera of the present invention is capable of bearing the pressure applied to the upper surface of the rear shell during fastening by providing a fastening receiving portion on the surface of the upper surface of the rear shell body on the outer surface side of the rear shell body and at a position opposite to the protruding member. Therefore, even when the connector module is fixedly connected to the rear shell body by fastening, the structural strength of the rear shell for the vehicle-mounted camera can be ensured.

[0016] In addition, in the back cover for a vehicle-mounted camera of the present invention, the terminals that can be electrically connected from one end side to the other end side can effectively connect the vehicle-mounted camera to the outside.

[0017] In addition, the back cover for a vehicle-mounted camera of the present invention has a flat flange portion in which a plurality of engagement holes are formed in the outer shell, so that the outer shell can be easily engaged with the back cover body and the housing.

[0018] In addition, the vehicle camera back cover of the present invention has a flange receiving surface as a recessed portion for receiving the flange portion provided on the inner surface side of the back cover upper surface, and a protruding member provided on the flange receiving surface, so that the dimension of the interior of the back cover body in a direction perpendicular to the back cover upper surface, i.e., in a height direction, can be suppressed. Therefore, even if the size of the vehicle camera to be stored in the vehicle camera cover is large, the vehicle camera can be stored in the vehicle camera cover.

[0019] In the vehicle camera back cover of the above structure, it is preferable to adopt a structure in which the housing has a housing flange with an enlarged diameter and a housing O-ring for waterproofing fitted between the housing flange and the inner surface of the housing.

[0020] With this structure, the vehicle camera back cover of the present invention can prevent water from flowing into the vehicle camera back cover through the outer shell because the waterproof O-ring is fitted between the outer shell flange and the inner surface of the housing.

[0021] In the vehicle-mounted camera back cover having the above-mentioned structure, it is preferable to adopt a structure in which the insertion hole is circular and formed at the center of the upper surface of the back cover.

[0022] With this structure, the vehicle camera back cover of the present invention has the insertion hole formed in the center of the back cover upper surface, so it is very suitable when the position of the camera substrate in the vehicle camera cover connected to the connector module is arranged at a position opposite to the center of the back cover upper surface.

[0023] In the back shell for a vehicle-mounted camera of the above-mentioned structure, the following structure is preferably adopted, wherein the four sides constituting the outer periphery of the upper surface of the above-mentioned back shell are respectively set as the first side, the second side, the third side, and the fourth side, the first side is opposite to the third side, and the second side is opposite to the fourth side, and when the closest distance between the outer edge of the above-mentioned insertion hole and the first side is set to L1, the closest distance to the second side is set to L2, the closest distance to the third side is set to L3, and the closest distance to the fourth side is set to L4, the position of the insertion hole is offset from the center of the upper surface of the above-mentioned back shell in such a way that the above-mentioned L1 and the above-mentioned L3 become different values.

[0024] Through this structure, the rear shell for the vehicle-mounted camera of the present invention has a through hole formed at a position offset from the center of the upper surface of the rear shell to the first side or the third side. Therefore, it is very suitable to configure the position of the camera substrate in the shell for the vehicle-mounted camera connected to the connector module at a position opposite to the position offset from the center of the upper surface of the rear shell to the first side or the third side.

[0025] In the vehicle-mounted camera back cover of the above structure, it is preferable to adopt a structure in which the position of the insertion hole is offset from the center of the upper surface of the back cover so that the L2 and the L4 have different values.

[0026] Through this structure, the rear shell for the vehicle-mounted camera of the present invention has a through hole formed at a position offset from the center of the upper surface of the rear shell to the second side or the fourth side. Therefore, it is very suitable to arrange the position of the camera substrate in the shell for the vehicle-mounted camera connected to the connector module at a position opposite to the position offset from the center of the upper surface of the rear shell to the second side or the fourth side, that is, at a corner side of the upper surface of the rear shell.

[0027] In the rear shell for a vehicle-mounted camera of the above-mentioned structure, the following structure is preferably adopted, wherein at least one of the above-mentioned protrusion parts on the shorter side of the above-mentioned L1 or the above-mentioned L3 is a side protrusion provided on the upper surface of the above-mentioned inner surface side rear shell, and the above-mentioned side protrusion is fastened in a state where the above-mentioned flange part is engaged with the above-mentioned flange bearing surface.

[0028] When the insertion hole is offset from the center of the upper surface of the rear shell, it is sometimes impossible to ensure space for forming a protrusion on the rear shell and providing a structure for inserting the engaging hole of the flange portion. If the flange portion using the protrusion cannot be fixed, the outer shell cannot be fully fixed to the rear shell. However, with the above-mentioned structure, even if the space for forming the protrusion member on the upper surface of the rear shell on the inner surface side is small, the flange portion of the outer shell can be fully fixed to the rear shell by providing the side protrusion.

[0029] In the vehicle-mounted camera back cover having the above-mentioned structure, it is preferable to adopt a structure in which the side projection is formed by extending from the side surface of the back cover.

[0030] The side projections fix the flange of the housing to the rear housing after being fastened. By adopting a structure in which the side projections extend from both the upper surface of the rear housing on the inner surface side and the side surface of the rear housing as described above, the flange of the housing can be more firmly fixed to the rear housing than when the side projections extend only from the upper surface of the rear housing on the inner surface side. This is because, when the housing is subjected to a load in a direction perpendicular to the upper surface of the rear housing on the inner surface side, the load borne by the side projections is borne not only at the connection portion with the upper surface of the rear housing on the inner surface side, but also at the connection portion with the side surface of the rear housing, that is, the direction in which the load is borne can be dispersed.

[0031] In the above-mentioned rear shell for a vehicle-mounted camera, the following structure is preferably adopted, wherein at least one of the above-mentioned protruding parts is a side protrusion provided at the corner of the upper surface of the above-mentioned inner surface side rear shell, and the above-mentioned side protrusion is fastened in a state where the above-mentioned flange part is engaged with the above-mentioned flange receiving surface.

[0032] The appropriate position of the side protrusion should be set according to the size and shape of the flange. As in the above structure, the side protrusion is set at the corner of the upper surface of the inner surface side rear shell, which is very suitable for fastening, especially when the outer edge of the flange is located at a position close to any corner of the upper surface of the inner surface side rear shell.

[0033] In the vehicle-mounted camera back cover having the above structure, it is preferable to adopt a structure in which the side projection is provided on the flange receiving surface, the flange portion has a cutout portion, and the side projection is engaged with and fastened to the cutout portion.

[0034] By providing the notch portion in the flange portion as in the above-described configuration, the flange portion can be arranged on the concave flange receiving surface, and the dimension in the direction perpendicular to the upper surface of the rear housing, that is, in the height direction, can be suppressed.

[0035] In the above-mentioned rear cover for a vehicle-mounted camera, it is preferred that the protruding part on the shorter side of the L1 or L3 and the shorter side of the L2 or L4 is a side protrusion provided on the upper surface of the inner surface side rear cover.

[0036] On the shorter side of L1 or L3 and the shorter side of L2 or L4, there is sometimes less space for providing the protruding member on the upper surface of the inner surface side rear shell. However, with the above-mentioned structure, even if there is less space for forming the protruding member on the upper surface of the inner surface side rear shell, the flange portion of the outer shell can be sufficiently fixed to the rear shell by the side protrusion.

[0037] Preferably, a vehicle camera housing is constructed by joining a rear housing and a front housing for the vehicle camera having the above-mentioned structure to form a space for storing the vehicle camera.

[0038] With this structure, when the connector module is fixedly connected to the rear shell body of the vehicle-mounted camera housing of the present invention, heat is not generated by welding, but the protruding member protruding on the rear shell upper surface of the rear shell body is fastened in a state of being engaged with the connector module. Since the fixed connection by fastening is not accompanied by heat generation, even if a part of the connector module is made of resin, the resin part will not be deformed or damaged by heat. Therefore, the frequency of inferior products produced during the manufacture of the vehicle-mounted camera housing can be suppressed.

[0039] In addition, the method of using fastening is a method of applying pressure to the upper surface of the rear shell provided with the protruding member, but the vehicle camera case of the present invention is capable of bearing the pressure applied to the upper surface of the rear shell during fastening by providing a fastening receiving portion on the upper surface of the rear shell and at a position opposite to the protruding member. Therefore, even when the connector module is fixedly connected to the rear shell body by fastening, the structural strength of the vehicle camera case can be ensured.

[0040] Effects of the Invention

[0041] According to the present invention, it is possible to provide a vehicle camera case or a vehicle camera back case which can ensure the structural strength of the vehicle camera case or the vehicle camera back case and suppress the frequency of inferior products during manufacturing.

Figure 1 The X direction is called the horizontal direction, the Y direction is called the depth direction, and the Z direction is called the height direction. Figure 2 The same applies hereinafter. The positive direction of the Z direction is referred to as the upper side or the connector side, and the negative direction is referred to as the lower side or the front housing side.

[0063] (Car camera housing)

[0064] The vehicle camera housing 1 includes a rear housing 3 and a front housing 2. The vehicle camera housing 1 is formed by joining the rear housing 3 and the front housing 2 in a manner that the rear housing 3 and the front housing 2 are opposed to each other, thereby forming a space for accommodating a vehicle camera 4 described later. The rear housing 3 and the front housing 2 are joined, for example, by an adhesive, but may also be joined by other mechanical methods, welding, or the like. The vehicle camera housing 1 constitutes the vehicle camera housing of the present invention. The front housing 2 constitutes the front housing of the present invention. The rear housing 3 constitutes the rear housing of the vehicle camera of the present invention.

[0069] Figure 2 2 is a diagram showing the entire rear housing 3. Figure 2 (a) is a stereoscopic view from the top. Figure 2 (b) is a perspective view viewed from the bottom. Figure 3 It is an exploded perspective view of the rear housing 3. Figure 4 It is a bottom view of the rear housing 3. Figure 5(a) The rear shell 3 is Figure 4 The sectional view of section A-A in Figure 5 (b) is a cross-sectional view at the B-B section.

[0070] The rear housing 3 includes a rear housing body 10, a connector module 40, and a housing 30. Figure 2 As shown in (a) and (b), the cylindrical housing 30 protrudes from the upper surface of the rear housing body 10 and accommodates the connector module 40. Figure 5 As shown in (a) and (b), the connector module 40 is engaged with the rear case body 10 and the housing 30. The rear case 3 is connected to the external connector 6 and the vehicle camera substrate 5, and the two can be electrically connected.

[0071] (Back shell body)

[0072] Figure 6 Represents the rear shell body 10, Figure 6 (a) is a stereoscopic view from the top. Figure 6 (b) is a perspective view viewed from the bottom. Figure 7 1 is a schematic diagram for explaining the position of the insertion hole of the rear cabinet body 10 .

[0073] The rear shell body 10 is a box-shaped shell with an insertion hole 22 and one side open, formed by joining it to the front shell 2 in an opposed manner to form a space for storing the vehicle-mounted camera 4. The rear shell body 10 is made of aluminum, for example, but can also be made of other metals such as copper. The box-shaped rear shell body 10 is a shape similar to a rectangular parallelepiped, which is open in the negative direction of the Z direction, that is, at the bottom in the figure.

[0074] (top surface of rear shell, side surface of rear shell)

[0075] like Figure 6 As shown in (a) and (b), the rear shell body 10 is composed of the upper rear shell surface 11 and four rear shell side surfaces 12, 13, 14, and 15. The rear shell upper surface 11 constitutes the rear shell upper surface of the present invention. The rear shell side surfaces 12, 13, 14, and 15 constitute the rear shell side surfaces of the present invention.

[0076] The surface facing the rear case upper surface 11 is open. The upper surface of the rear case upper surface 11 is the outer surface side rear case upper surface 11a, and the lower surface is the inner surface side rear case upper surface 11b. The inner surface side rear case upper surface 11b of the rear case upper surface 11 faces the front case 2 in the Z direction.

[0077] like Figure 6As shown in (b), a flange receiving surface 11b1 and side protrusions 18, 19, 20, 21 are provided on the inner surface side rear shell upper surface 11b. The flange receiving surface 11b1 is provided as a recessed portion for receiving the flange portion 51 described later on the surface of the inner surface side rear shell upper surface 11b of the rear shell upper surface 11. An insertion hole 22 is formed on the flange receiving surface 11b1, and flange receiving surface protrusions 16, 17 that engage with the connector module 40 described later are provided. In addition, the inner surface side rear shell upper surface 11b mentioned in this embodiment is a concept that also includes the flange receiving surface 11b1. Therefore, for example, the flange receiving surface 11b1 also means the inner surface side rear shell upper surface 11b.

[0078] (Raised parts)

[0079] like Figure 6 As shown in (b), the flange receiving surface protrusions 16 and 17 are protruding parts that protrude in a vertical direction from the rear shell upper surface 11 toward the inner surface side of the rear shell body 10 and are provided on the inner surface side of the rear shell upper surface 11b that engages with the connector module 40. The flange receiving surface protrusions 16 and 17 constitute the protruding parts of the present invention.

[0080] The flange receiving surface protrusions 16 and 17 are fastened in a state of being engaged with the connector module 40, so that the connector module 40 is reliably fixed and connected to the rear housing body 10. The fastening is performed, for example, by pressing the flange receiving surface protrusions 16 and 17 in an upward direction, that is, in the positive direction of the Z direction, in a state of being engaged with the connector module 40 using a fastening tool or the like.

[0081] Figure 6 (b) shows the state before the flange receiving surface protrusions 16 and 17 are tightened, but the state after tightening the flange receiving surface protrusions 16 and 17 is as shown in FIG. Figure 2 (b) Figure 5 As shown in (b), the tops of the flange receiving surface protrusions 16 and 17 are enlarged in diameter by tightening.

[0082] In the present embodiment, two flange receiving surface protrusions 16 and 17 are provided as flange receiving surface protrusions, but the number of flange receiving surface protrusions is not limited thereto, and the length of the flange receiving surface protrusions may be changed according to the shape of the flange portion 51, etc.

[0083] The side projections 18 and 19 are respectively provided on the side of the rear shell upper surface 11b on the inner surface side, which is closer to the rear shell side surface 14. That is, the side projections 18 and 19 are provided on the rear shell upper surface 11b on the inner surface side, along the side corresponding to the shorter side of L1 or L3 described later, that is, the rear shell side surface 14. The side projections 18 and 19 are formed by extending from the rear shell side surface 14. The side projections 18 and 19 are projection components for fastening the flange portion 51 described later to the flange receiving surface 11b1 in order to engage the rear shell body 10 with the connector module 40. The side projections 18 and 19 constitute the projection components of the present invention.

[0084] Figure 6 (b) shows the state before the side protrusions 18 and 19 are tightened, but the state after tightening the side protrusions 18 and 19 is as shown in FIG. Figure 2 (b) Figure 5 As shown in (b), deformation portions 18a and 19a are formed by deforming the side projections 18 and 19 by tightening a part of them.

[0085] The side protrusions 20 are respectively provided on the inner surface side rear shell upper surface 11b, on the side closer to the rear shell side surface 13. The side protrusions 20 are formed by extending from the rear shell side surface 13. The side protrusions 20 are protrusion components for engaging the rear shell body 10 with the connector module 40 so that the flange portion 51 described later is engaged with the flange receiving surface 11b1 and fastened. The side protrusions 20 constitute the protrusion components of the present invention.

[0086] Figure 6 (b) shows the state before the side protrusion 20 is tightened, but the state after tightening the side protrusion 20 is as shown in FIG. Figure 2 (b) Figure 5 As shown in (b), a deformed portion 20a is formed by deforming a part of the side protrusion 20 by tightening.

[0087] The side projections 21 are respectively provided on the inner surface side rear shell upper surface 11b on the side closer to the rear shell side surface 15. The side projections 21 are formed by extending from the rear shell side surface 15. The side projections 21 are projection components for fastening the rear shell body 10 and the connector module 40 so that the flange portion 51 described later is engaged with the flange receiving surface 11b1. The side projections 21 constitute the projection components of the present invention.

[0088] Figure 6 (b) shows the state before the side protrusion 21 is tightened, but the state after tightening the side protrusion 21 is as shown in FIG. Figure 2 (b) Figure 5 As shown in (b), a deformed portion 21a is formed by deforming a part of the side protrusion 21 by tightening.

[0089] As described above, by adopting a structure in which the side projections 18, 19, 20, 21 extend from both the inner side rear case upper surface 11b and the rear case side surfaces 13, 14, 15, the flange portion 51 of the housing 50 can be more firmly fixed to the rear case 3 than when the flange portion 51 extends only from the inner side rear case upper surface 11b. This is because, when the housing 50 receives a load in a direction perpendicular to the inner side rear case upper surface 11b, the load received by the side projections 18, 19, 20, 21 is received not only at the connection portion with the inner side rear case upper surface 11b, but also at the connection portion with the rear case side surfaces 13, 14, 15, that is, the direction in which the load is received can be dispersed.

[0090] In the present embodiment, four side protrusions 18, 19, 20, and 21 are provided, but the number of the side protrusions is not limited thereto, and the locations where the side protrusions are arranged may be changed as appropriate.

[0091] The rear case side surfaces 12 , 13 , 14 , and 15 as the four side surfaces of the rear case 3 are provided vertically downward, that is, in the negative direction of the Z direction, along the outer circumference of the rear case upper surface 11 .

[0092] like Figure 6 As shown in (a), a fastening receiving surface 11a1 is provided around the insertion hole 22 of the upper surface 11a of the outer surface side rear shell. Figure 5 As shown in (b), the fastening receiving surface 11a1 is provided on the surface of the outer surface side rear case upper surface 11a of the rear case upper surface 11, which is the outer surface side of the rear case main body 10 and faces the flange receiving surface protrusions 16 and 17.

[0093] (Fastening receiving part)

[0094] Generally, fixing by fastening applies pressure to the protruding parts and the like, and thus sometimes applies a load on the strength of the shell. However, the rear shell 3 of the present embodiment is capable of withstanding the pressure applied to the rear shell upper surface 11 during fastening by providing a fastening receiving surface 11a1 on the rear shell upper surface 11a of the outer surface side of the rear shell upper surface 11, which is the outer surface side of the rear shell main body 10, at a position opposite to the flange receiving surface protrusions 16, 17 and the side protrusions 18, 19, 20, 21 as each protruding part, on the rear shell upper surface 11a of the present embodiment. Therefore, even when the connector module 40 is fixedly connected to the rear shell main body 10 by fastening, the structural strength of the rear shell 3 can be maintained. The fastening receiving surface 11a1 constitutes the fastening receiving portion of the present invention.

[0095] like Figure 7 As shown, the insertion hole 22 is formed at a position offset in the negative direction of the y direction from the center of the rear case upper surface 11. The degree of offset of the insertion hole 22 from the center of the rear case upper surface 11 will be described below.

[0096] Figure 7 The inner surface side rear shell upper surface 11b of the rear shell upper surface 11 is viewed from the bottom, that is, from the negative direction of the Z direction. The side corresponding to the rear shell side surface 12 of the inner surface side rear shell upper surface 11b is set as the side 12a, the side corresponding to the rear shell side surface 13 is set as the side 13a, the side corresponding to the rear shell side surface 14 is set as the side 14a, and the side corresponding to the rear shell side surface 15 is set as the side 15a. At this time, the sides 12a, 13a, 14a, and 15a are four sides constituting the outer periphery of the inner surface side rear shell upper surface 11b, and the side 12a is opposite to the side 14a. In addition, the side 13a is opposite to the side 15a.

[0097] The closest distance between the outer edge of the insertion hole 22 and the side 12a is L1, the closest distance to the side 13a is L2, the closest distance to the side 14a is L3, and the closest distance to the side 15a is L4. At this time, in the present embodiment, as L1>L3, the position of the insertion hole 22 is offset from the center of the inner surface side rear case upper surface 11b so that L1 and L3 have different values.

[0098] In this way, by forming the insertion hole 22 at a position offset from the center of the inner surface side rear shell upper surface 11b to the side 12a or the side 14a, it is possible to correspond to the situation where the position of the vehicle camera substrate 5 in the vehicle camera shell 1 connected to the connector module 40 is arranged at a position opposite to the position offset from the center of the inner surface side rear shell upper surface 11b to the side 12a or the side 14a.

[0099] (Connector module)

[0100] At least a part of the connector module 40 is made of resin, electrically connects the external connector 6 to the vehicle-mounted camera substrate 5, is inserted into the insertion hole 22, engages with the rear shell body 10 and the housing 30 described later, and protrudes to the outside of the rear shell body 10 to engage with the external connector 6. Specifically, the resin-made parts are the housing 30, the insulator 70, the housing O-ring 85, and the insulator O-ring 86 described later. The connector module 40 is fixedly connected to the rear shell body 10 by tightening the flange receiving surface protrusions 16 and 17 in a state of engaging with the flange receiving surface protrusions 16 and 17. The connector module 40 includes a housing 50, a terminal 60, and an insulator 70. The connector module 40 constitutes a connector module of the present invention.

[0101] (shell)

[0102] Figure 8 2 shows a housing 50 of this embodiment. Figure 8 (a) is a stereoscopic view from the top. Figure 8(b) is a perspective view from the bottom. The housing 50 is made of metal such as zinc die-casting, and is a conductor having a cylindrical portion. The housing 50 has a flange portion 51, an upper housing 52, a lower housing 54, a housing flange 55, and a housing O-ring 85. The housing 50 constitutes the housing of the present invention.

[0103] The flange portion 51 is a flat plate-shaped component that is respectively formed with a central through hole 56A, a plurality of housing boss holes 56a, 56b, 56c, 56d as engagement holes, and rear housing boss holes 57a, 57b, and is engaged with the rear housing body 10 and the housing 30, respectively. When the flange portion 51 engages with the flange bearing surface bosses 16, 17 of the rear housing body 10, the flange bearing surface bosses 16, 17 penetrate the rear housing boss holes 57a, 57b. The central through hole 56A is passed through by a terminal 60 to be described later in the housing 50, and is provided so as to be in contact with and conductive with the vehicle-mounted camera substrate 5. In the present embodiment, four housing boss holes are formed and two rear housing boss holes are formed, but the number of boss holes is not limited thereto. In addition, the arrangement of the boss holes may also be the same as that of the rear housing body 10. Figure 8 Examples of different configurations.

[0104] The cylindrical portion of the housing 50 is composed of an upper housing 52, a lower housing 54, and a housing flange 55 from the top along the Z direction. The cylindrical portion of the housing 50 accommodates and fixes an insulator 70 described later. The upper housing 52 is located at the top of the cylindrical portion of the housing 50. The upper housing 52 and the housing 30 are fitted with the external connector 6.

[0105] like Figure 5 As shown in (a), the upper housing 52 contains the insulator 70. The lower housing 54 contains the insulator 70. The lower housing 54 is a cylindrical portion of the housing 50 connected to the lower side of the upper housing 52 and is larger in diameter than the upper housing 52.

[0106] The housing flange 55 is a portion connected to the lower portion of the lower housing 54 and to the upper portion of the flange portion 51. The housing flange 55 has an outer diameter that further increases the diameter of the lower housing 54. Figure 5 As shown in (a), the housing flange 55 is a structure that allows a housing O-ring 85 for waterproofing to be embedded between the housing flange 55 and the inner surface of the housing 30 described later. The housing O-ring 85 is made of resin such as ethylene propylene rubber. By providing the housing O-ring 85, it is possible to prevent water from flowing into the rear housing for the vehicle-mounted camera from the external connector side.

[0107] (terminal)

[0108] Figure 3The terminal 60 shown is arranged inside the housing 50 along the central axis, and can be conducted from one end side to the other end side, that is, it contacts the external connector 6 on the positive direction side of the Z direction as one end side, and contacts and conducts with the substrate connector 5a of the vehicle camera substrate 5 on the negative direction side of the Z direction as the other end side. The terminal 60 is made of, for example, a copper alloy, but may also be made of other metals. The terminal 60 constitutes the terminal of the present invention. The terminal 60 is held by an insulator 70 described later, for example, by engaging a not-shown engaging portion.

[0109] (Insulator)

[0110] Figure 3 The insulator 70 shown is a member interposed between the housing 50 and the terminal 60 to maintain the insulation of the terminal 60. The insulator 70 is composed of a body portion 71 and an O-ring groove portion 72. The insulator 70 is made of a resin such as polyamide, for example. The insulator 70 constitutes the insulator of the present invention.

[0111] A terminal through hole 73 is formed in the center of the insulator 70 and penetrates in the Z direction. The terminal 60 extends inside the terminal through hole 73. The terminal through hole 73 is composed of a through hole 73a with a large diameter on the upper side and a through hole 73b with a small diameter on the lower side. The through hole 73a can be engaged with the external connector 6. The through hole 73b has an outer diameter substantially the same as that of the terminal 60 and functions as a hole for protecting the terminal 60. The insulator 70 holds the terminal 60, for example, by engaging a snap-fit ​​portion not shown in the figure. The insulator 70 is fixed to the outer housing 50, so that the positional relationship with other components of the connector module 40 is fixed.

[0112] The body 71 is a cylindrical member constituting the insulator 70. The terminal 60 extends in the vertical direction (Z direction) in the internal space of the body 71. The body 71 is arranged in a housing space of the housing 30 described later, and is fitted with the external connector 6.

[0113] The O-ring groove 72 is a groove-shaped portion provided near the center in the height direction of the body 71, and has an outer diameter smaller than the outer diameter of the body 71. The O-ring groove 72 is a groove for inserting the insulator O-ring 86.

[0114] The insulating O-ring 86 is made of resin such as ethylene propylene rubber, for example. By providing the insulating O-ring 86, water is prevented from flowing into the vehicle-mounted camera rear case from the external connector side.

[0115] (case)

[0116] Fig. 9 30 of this embodiment, Fig. 9 (a) is a stereoscopic view from the top. Fig. 9(b) is a perspective view from the bottom. The housing 30 engages with the connector module 40, stores and releases the connector module 40, and engages with the external connector 6. The housing 30 has a cylindrical portion 31, a locking portion 32, a housing flange 33, and flange protrusions 34a, 34b, 34c, and 34d. The housing 30 is made of a resin such as polyamide, for example. The housing 30 constitutes the housing of the present invention.

[0117] The cylindrical portion 31 accommodates the connector module 40 in the internal accommodation space and is engaged with the external connector 6. A locking portion 32 is provided in a protruding manner on the side of the cylindrical portion 31. The locking portion 32 is engaged with the engaging portion of the external connector 6 (not shown), thereby fixing the positional relationship between the housing 30 and the external connector 6.

[0118] The housing flange 33 is a disc-shaped member connected to the lower part of the cylindrical portion 31, and has an outer diameter larger than the outer diameter of the cylindrical portion 31. The housing flange 33 is embedded in the insertion hole 22 of the rear shell 3. When the housing flange 33 is embedded in the insertion hole 22, an adhesive 87 is inserted in the gap between the housing flange 33 and the rear shell 3. In this embodiment, an elastic adhesive that hardens by moisture is used as the adhesive 87, but other types of adhesives can also be used. By using the adhesive 87, the positional relationship between the housing 30 and the rear shell 3 can be fixed.

[0119] Flange protrusions 34a, 34b, 34c, and 34d are provided on the lower surface of the shell flange 33. In the present embodiment, four flange protrusions are provided, but the number of flange protrusions is not necessarily limited thereto, and may be a different number. The flange protrusion 34a is tightened in the positive direction of the Z direction when it is engaged with the shell protrusion hole 56a of the outer shell 50. Similarly, the flange protrusion 34b is tightened in the positive direction of the Z direction when it is engaged with the shell protrusion hole 56b of the outer shell 50, the flange protrusion 34c is tightened in the positive direction of the Z direction when it is engaged with the shell protrusion hole 56c of the outer shell 50, and the flange protrusion 34d is tightened in the positive direction of the Z direction when it is engaged with the shell protrusion hole 56d of the outer shell 50. By tightening the flange protrusions 34a, 34b, 34c, and 34d in this way, Figure 2 (b) Figure 5 As shown in (a), the housing 30 is fixed to the casing 50.

[0120] (Preparation method)

[0121] Reference Figure 3 , the manufacturing process of the rear shell 3 is described.

[0122] (1) The terminal 60 is inserted into the insulator 70 , and the terminal 60 is held by the insulator 70 .

[0123] (2) Next, the insulator O-ring 86 is inserted into the O-ring groove 72 of the insulator 70 .

[0124] (3) Next, the insulator 70 is inserted into the central through hole 56A of the housing 50 from below, and the insulator 70 is fixed.

[0125] (4) Next, the case O-ring 85 is mounted on the case 50 , and the connector module 40 is completed.

[0126] (5) Next, the connector module 40 is inserted into the insertion hole 22 of the rear housing body 10 from below and fixed by fastening.

[0127] (6) Next, the housing 30 is engaged with the connector module 40 from above and fixed by fastening.

[0128] (7) Finally, the adhesive 87 is applied between the housing 30 and the rear case body 10 to fix them.

[0129] As described above, the vehicle camera case 1 of the present embodiment forms a space for housing the vehicle camera 4 by joining the rear case 3 and the front case 2 .

[0130] The rear shell 3 of the present embodiment comprises: a box-shaped rear shell body 10, which is joined to the front shell 2 in a manner opposing to form a space for accommodating the vehicle-mounted camera 4, and is formed with an insertion hole 22 and has one side open; a connector module 40, which electrically connects the external connector 6 to the vehicle-mounted camera substrate 5, is inserted into the insertion hole 22, is engaged with the rear shell body 10, and at least a portion thereof protruding to the outside of the rear shell body 10 and engaged with the external connector 6 is made of resin; and a shell 30, which is engaged with the connector module 40, accommodates the connector module 40, and is connected to the external connector 6. The rear shell body 10 has: a rear shell upper surface 11, which is opposed to the front shell 2; and a plurality of rear shell side surfaces 12, 13. , 14, 15, which are vertically arranged along the outer periphery of the rear shell upper surface 11; flange bearing surface protrusions 16, 17, which protrude in a vertical direction from the rear shell upper surface 11 toward the inner surface side of the rear shell main body 10 and are arranged on the inner surface side rear shell upper surface 11b of the inner surface side of the rear shell upper surface 11 engaged with the connector module 40; and a fastening bearing surface 11a1, which is arranged on the outer surface side rear shell upper surface 11a of the rear shell upper surface 11 on the outer surface side of the rear shell main body 10 of the rear shell upper surface 11 and at a position opposite to the flange bearing surface protrusions 16, 17 and the side protrusions 18, 19, 20, 21, the flange bearing surface protrusions 16, 17 are fastened in a state of being engaged with the connector module 40.

[0131] In addition, the connector module 40 has: a shell 50 serving as a conductor, which is made of metal and has a cylindrical portion; a terminal 60, which is arranged along the central axis on the inner side of the shell 50, is in contact with the external connector 6 at one end, and is in contact with and conductive with the substrate connector 5a of the substrate 5 for the vehicle-mounted camera at the other end; and an insulating insulator 70, which is interposed between the shell 50 and the terminal 60 to hold the terminal 60.

[0132] In addition, the outer shell 50 also has a flat flange portion 51, which is formed with raised holes 57a, 57b for the rear shell and raised holes 56a, 56b, 56c, and 56d for the shell, which are respectively engaged with the rear shell body 10 and the shell 30. When the flange portion 51 is engaged with the flange bearing surface protrusions 16 and 17 of the rear shell body 10, the flange bearing surface protrusions 16 and 17 pass through the raised holes 57a and 57b for the rear shell.

[0133] The housing 50 also includes a housing flange 55 having an enlarged diameter and a housing O-ring 85 for waterproofing that is fitted between the housing flange 55 and the inner surface of the case 30 .

[0134] The back case body 10 has a flange receiving surface 11b1 as a recessed portion for receiving the flange portion 51 on the inner back case upper surface 11b of the back case upper surface 11, and flange receiving surface protrusions 16 and 17 are provided on the flange receiving surface 11b1.

[0135] In addition, when the four sides constituting the outer periphery of the rear shell upper surface 11 are respectively set as side 12a, side 13a, side 14a, and side 15a, and side 12a is opposite to side 14a, and side 13a is opposite to side 15a, and the closest distance between the outer edge of the through hole 22 and side 12a is set to L1, the closest distance to side 13a is set to L2, the closest distance to side 14a is set to L3, and the closest distance to side 15a is set to L4, as L1>L3, it is a structure in which the position of the through hole 22 is offset from the center of the rear shell upper surface 11 in such a way that L1 and L3 become different values.

[0136] The protruding part in the rear shell side surface 14 corresponding to the shorter side of L1 or L3 is a side protrusion 18, 19 provided on the inner surface side rear shell upper surface 11b, and the side protrusions 18, 19 are a structure that is fastened so that the flange part 51 is engaged with the flange receiving surface 11b1.

[0137] In addition, the side protrusions 18 and 19 are structures extending from the rear shell side surface 14 , the side protrusion 20 is a structure extending from the rear shell side surface 13 , and the side protrusion 21 is a structure extending from the rear shell side surface 15 .

[0138] According to this structure, when the connector module 40 is fixedly connected to the rear case body 10 of the vehicle-mounted camera case 1 of the present embodiment, heat is not generated by welding, but the flange receiving surface protrusions 16 and 17 protruding in the vertical direction toward the inner surface side on the rear case upper surface 11 of the rear case body 10 are fastened and fixedly connected in a state of being engaged with the connector module 40. Since the fixed connection by fastening is not accompanied by heat generation, even if a part of the connector module 40 is made of resin, the resin part will not be deformed or damaged by heat. Therefore, the frequency of inferior products during the manufacture of the rear case 3 can be suppressed.

[0139] In addition, the method using fastening is a method of applying pressure to the rear shell upper surface 11 provided with the flange receiving surface protrusions 16 and 17, but the rear shell 3 can withstand the pressure applied to the rear shell upper surface 11 during fastening by providing the fastening receiving surface 11a1 on the outer surface side rear shell upper surface 11a of the rear shell main body 10 and at a position opposite to the flange receiving surface protrusions 16 and 17 and the side protrusions 18, 19, 20, and 21. Therefore, even when the connector module 40 is fixedly connected to the rear shell main body 10 by fastening, the structural strength of the rear shell 3 can be ensured.

[0140] In addition, in the rear shell 3 of this embodiment, the terminal 60 held by the insulator 70 on the inner side of the outer shell 50 contacts the external connector 6 at one end, and contacts the vehicle camera substrate 5 at the other end, so that the external connector 6 and the vehicle camera substrate 5 can be effectively electrically connected.

[0141] In addition, since the back shell 3 of this embodiment has a flat flange portion 51 formed with rear shell boss holes 57a, 57b and case boss holes 56a, 56b, 56c, 56d, the connector module 40 can be easily engaged with the back shell body 10 and the case 30.

[0142] In addition, the back case 3 of this embodiment has the outer case O-ring 85 for waterproofing fitted between the outer case flange 55 and the inner surface of the housing 30 , thereby preventing water from flowing into the back case 3 from the external connector 6 side through the outer case 50 .

[0143] In addition, the back case 3 of the present embodiment has a flange receiving surface 11b1 as a recessed portion for receiving the flange portion 51, and flange receiving surface projections 16 and 17 are provided on the flange receiving surface 11b1, so that the dimension of the back case body 10 in the direction perpendicular to the back case upper surface 11, that is, the height direction can be suppressed. Therefore, even if the size of the vehicle camera 4 housed in the vehicle camera case 1 is large, the vehicle camera 4 can be housed in the vehicle camera case 1.

[0144] In addition, since the through hole of the rear shell 3 of this embodiment is formed at a position offset from the center of the upper surface 11 of the rear shell to the side 12a or the side 14a, it is very suitable to configure the position of the camera substrate 5 in the shell 1 for the vehicle camera connected to the connector module 40 at a position opposite to the position offset from the center of the upper surface 11 of the rear shell to the side 12a or the side 14a.

[0145] In addition, even if the space for forming the protrusions on the inner rear case upper surface 11 b is small, the flange 51 of the outer case 50 can be sufficiently fixed to the rear case 3 by providing the side protrusions 18 and 19 .

[0146] In addition, the rear shell 3 of this embodiment is structured such that the side protrusions 18, 19, 20, 21 extend from both the inner surface side rear shell upper surface 11b and the rear shell side surfaces 13, 14, 15, thereby enabling the flange portion 51 of the outer shell 50 to be more firmly fixed to the rear shell 3 than when it only extends from the inner surface side rear shell upper surface 11b.

[0147] (Second Embodiment)

[0148] In this embodiment, the insertion hole 122 of the rear shell 103 is formed at the center of the upper surface 111 of the rear shell and the shape of the flange portion 151 of the outer shell 150 is changed. The other structures are substantially the same as those of the first embodiment. In the rear shell 103 of the second embodiment, the same components as those of the first embodiment are used. Figures 1 to 9 The same reference numerals as those in the first embodiment are used, and only the differences are described in detail.

[0149] The arrangement of the insertion holes in the rear case 103 needs to be determined according to the arrangement of the vehicle camera 4 and the vehicle camera substrate 5 in the vehicle camera case 1. In this embodiment, it is assumed that the vehicle camera 4 and the vehicle camera substrate 5 are arranged at positions opposite to the center of the rear case upper surface 111.

[0150] (Back shell)

[0151] Fig.10 2 is a diagram showing a rear case according to the present embodiment. Fig.10 (a) is a stereoscopic view from the top. Fig.10 (b) is a perspective view viewed from the bottom. Fig.11 2 is a diagram showing a rear shell body according to the present embodiment. Fig.11 (a) is a stereoscopic view from the top. Fig.11 (b) is a stereoscopic view from the bottom. Fig.11As shown in (a) and (b), the position of the insertion hole 122 in the rear shell upper surface 111a on the outer surface side of the rear shell 103 is different from that in the first embodiment. The insertion hole 122 is circular and formed in the center of the rear shell upper surface 111. Accordingly, the housing 30 is also arranged in the center of the rear shell upper surface 111.

[0152] (Upper surface of rear case)

[0153] The inner surface side rear shell upper surface 111b is provided with a flange receiving surface 111b1. The flange receiving surface 111b1 is a circular concave portion that matches the shape of the flange portion 151 described later. In addition, the inner surface side rear shell upper surface 111b mentioned in this embodiment is a concept that also includes the flange receiving surface 111b1. Therefore, for example, on the flange receiving surface 111b1 also means on the inner surface side rear shell upper surface 111b.

[0154] Fig.12 The inner surface side rear shell upper surface 111b of the rear shell upper surface 111 is viewed from the bottom, that is, from the negative direction of the Z direction. In the present embodiment, the insertion hole 122 is located at the center of the inner surface side rear shell upper surface 111b, and is therefore arranged at a position where the relationship L1=L3 and L2=L4 holds. However, the position of the insertion hole 122 may be slightly offset from the center of the inner surface side rear shell upper surface 111b, and arranged so as to be within the following range.

[0155] 0.5<L1 / L3<2, 0.5<L2 / L4<2

[0156] Unlike the first embodiment, no side protrusions biased toward the side of the rear shell are provided on the inner surface side rear shell upper surface 111b. This is because, by forming the insertion hole 122 at the center of the rear shell upper surface 111, the flange receiving surface 111b1 can be fully expanded with the center of the inner surface side rear shell upper surface 111b as the center, and the four flange receiving surface protrusions 116, 117, 118, and 119 described later are provided on the flange receiving surface 111b1, so that the rear shell body 110 and the outer shell 150 can be engaged with sufficient strength.

[0157] (Fastening receiving part)
