Description

Technical Field

[0001] The present invention relates to a method for fixing a terminal module to a case housing an electronic device and a fixing structure of a terminal module to a case housing an electronic device.

Background Art

[0002] Conventionally, as a case housing an electronic device, for example, a terminal module for connecting and conducting a camera module including a camera in a camera case and an external cable or the like has been fixed to a camera case for housing the camera. Such a fixing structure of the camera case and the terminal module is required to have high waterproofness so that liquid such as water does not enter inside.

[0003] As such a fixing structure of the camera case and the terminal module, a fixing structure is disclosed by a method of inserting a first cylindrical shell 3 of a terminal module 30 and a plug case 10A with an external seal member 6 provided around the first cylindrical shell 3 into the plug case 10A and fixing them by a plurality of locking ribs 32 formed by crushing the first cylindrical shell 3 (see Patent Document 1). In the fixing structure disclosed in Patent Document 1, the external seal member 6 contacts the inner peripheral surface of the plug case 10A and the outer peripheral surface of the first cylindrical shell 3, thereby suppressing the intrusion of liquid into the cylindrical space of the plug case 10A.

[0004] In addition, in fields other than camera cases, in smartphones, tablet terminals, etc., a fixing method using a double-sided tape or an adhesive as a waterproof member 40 on the mounting surface of the terminal member 30 is also disclosed in order to waterproof and fix the terminal member 30 to the housing 10 (see Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the method of fixing the terminal module 30 disclosed in Patent Document 1 to the plug case 10A, in order to prevent water leakage, the step of wearing the seal member 6 on the first cylindrical shell 3 of the terminal module 30 is performed in advance. Further, in order to fix the terminal module 30 to the plug case 10A, a plurality of crushing shapes (locking ribs 32) are formed in advance on the first cylindrical shell 3, and then the step of crushing each of them is required. For this reason, when fixing the terminal module 30 to the plug case 10A, if a seal member 6 is applied to provide a waterproof function, there is a problem that the number of assembly steps increases.

[0007] Further, when trying to fix the terminal member 30 to the housing 10 using a double-sided tape or an adhesive as disclosed in Patent Document 2, although the number of steps is less than the method disclosed in Patent Document 1, there is a problem that the workability during assembly is poor. Specifically, regarding the work of fixing the terminal member 30 to the housing 10, adhesion with a double-sided tape requires sticking it to an appropriate position at once, and adhesion with an adhesive requires precise management of the liquid amount and application position and there is a concern of adhering to conductive parts such as terminals. Therefore, it is necessary to pay a high degree of attention, and since it is not an easy operation, the workability during assembly is poor.

[0008] The present invention has been made to solve such problems, and when fixing a terminal module to a case that houses an electronic device, it is possible to provide a waterproof function, reduce the number of assembly steps, and improve the workability during assembly. An object is to provide a method for fixing a terminal module to a case that houses an electronic device, and a fixing structure for a terminal module to a case that houses an electronic device.

Means for Solving the Problems

[0009] A method for fixing a terminal module to a case that houses an electronic device according to the present invention is, in order to achieve the above object, a method for fixing a terminal module to a case that houses an electronic device, wherein the case that houses the electronic device includes a first case having a through-hole formed therein and a cylindrical housing that communicates with the through-hole and protrudes to the outside, and a second case that houses an imaging element, and the first case and the second case are joined together; the terminal module includes a shell that is a cylindrical conductor having a flange portion with a larger diameter on the base end side than on the tip end side, a center contact disposed inside along the central axis of the shell, and an insulating member interposed between the shell and the center contact and holding the center contact; a step of disposing a thermal adhesive film for joining a plurality of members made of the same material or different materials around the outer edge of the through-hole on the inner surface side of the first case in a flange receiving portion formed; a step of inserting the terminal module from the tip end side into the through-hole until the flange portion contacts the flange receiving portion through the thermal adhesive film; a step of further pressing the terminal module into the through-hole by pressing the terminal module toward the inside of the housing after inserting the terminal module into the through-hole; and a step of heating the periphery of the flange receiving portion after the press-fitting.

[0010] With this configuration, in the method for fixing a terminal module to a case that houses an electronic device according to the present invention, a thermal adhesive film is disposed in the flange receiving portion of the first case, the terminal module is inserted into the through-hole and then press-fitted, and the thermal adhesive film sandwiched between the flange portion and the flange receiving portion is heated, so that the thermal adhesive film softens, and the terminal module and the first case are adhered and fixed.

[0011] Therefore, compared with the conventional method of previously wearing a sealing member such as an O-ring around the terminal module or the like, forming a locking structure for locking the sealing member to the terminal module, deforming the locking structure to fix the sealing member, and then inserting and press-fitting the terminal module into the case housing the electronic device to fix the terminal module to the case housing the electronic device, the method according to the present invention can reduce the assembly man-hours.

[0012] In addition, since the terminal module and the first case are adhered by the flange portion and the flange receiving portion, liquid will not enter the inside of the case housing the electronic device through the through hole from the outside of the case housing the electronic device, or conversely, liquid will not flow out from the inside of the case housing the electronic device to the outside of the case housing the electronic device through the through hole, and the case housing the electronic device has a waterproof function.

[0013] Moreover, the thermal adhesive film has no adhesiveness at room temperature and is easy to position, so it is relatively easy to place the thermal adhesive film on the flange receiving portion. Further, after press-fitting the terminal module into the through hole of the case housing the electronic device, the terminal module can be fixed to the case housing the electronic device only by heating the thermal adhesive film, so the operation is relatively easy.

[0014] On the other hand, fixing with a conventional double-sided tape or adhesive is not an easy operation because appropriate management such as the pasting position and the amount of liquid is required and high attention must be paid. Therefore, since the method according to the present invention includes a relatively easy operation process, the workability during assembly can be improved.

[0015] In the method of fixing the terminal module to the case housing the electronic device described above, in the step of press-fitting the terminal module into the through hole, the press-fitting position of the terminal module may be restricted on the tip side of the terminal module by a restricting portion formed on the inner peripheral surface of the housing.

[0016] With this configuration, the terminal module is fixed to the flange receiving portion by the heat adhesive film at the proximal end side and is fixed by being restricted by the restricting portion formed on the inner peripheral surface of the housing at the distal end side. Therefore, the terminal module is fixed to the case that houses the electronic device more firmly and stably than when it is fixed only at one end side of the terminal module.

[0017] A method for fixing a terminal module to a case that houses an electronic device according to the present invention is a method for fixing a terminal module to a case that houses an electronic device, wherein the case that houses the electronic device has a through hole formed therein and is provided with a first case having a cylindrical housing that communicates with the through hole and protrudes to the outside, and a second case that houses an imaging element, and the first case and the second case are joined together. The terminal module includes a shell that is a cylindrical conductor having a flange portion with a larger diameter at the proximal end side than at the distal end side, a center contact disposed inside along the central axis of the shell, and an insulating member interposed between the shell and the center contact and holding the center contact. The method includes a step of disposing a heat adhesive film for joining a plurality of members made of the same material or different materials around the outer edge of the through hole on the inner surface side of the first case at a flange receiving portion, a step of inserting the terminal module into the through hole from the distal end side to a position where the flange portion is in contact with the flange receiving portion via the heat adhesive film, and a step of heating the periphery of the flange receiving portion while further pressing the terminal module into the housing and press-fitting it into the through hole after inserting the terminal module into the through hole.

[0018] With this configuration, the method for fixing a terminal module to a case that houses an electronic device according to the present invention is to dispose a heat adhesive film at the flange receiving portion of the first case, insert the terminal module into the through hole and then press-fitting it, and at the same time heat the heat adhesive film sandwiched between the flange portion and the flange receiving portion so that the heat adhesive film softens, and the terminal module and the first case are adhered and fixed.

[0019] Therefore, compared with the conventional method of wearing a sealing member such as an O-ring around the terminal module in advance, forming a locking structure for locking the sealing member to the terminal module, deforming the locking structure to fix the sealing member, and then inserting and press-fitting the terminal module into the case that houses the electronic device to fix the terminal module to the case that houses the electronic device, the method according to the present invention can reduce the assembly man-hours. Also, by performing the press-fitting of the terminal module and the heating of the thermal adhesive film simultaneously, the working time can be shortened compared to the case of performing them separately.

[0020] Further, since the terminal module and the first case are adhered by the flange portion and the flange receiving portion, liquid will not enter from the outside of the case that houses the electronic device into the inside of the case that houses the electronic device through the through-hole, or conversely, liquid will not flow out from the inside of the case that houses the electronic device to the outside of the case that houses the electronic device through the through-hole, and the case that houses the electronic device has a waterproof function.

[0021] Also, since the thermal adhesive film has no adhesiveness at normal temperature and is easy to position, it is relatively easy to place the thermal adhesive film on the flange receiving portion. Furthermore, after press-fitting the terminal module into the through-hole of the case that houses the electronic device, the terminal module can be fixed to the case that houses the electronic device only by heating the thermal adhesive film, so the operation is relatively easy.

[0022] On the other hand, fixing with a conventional double-sided tape or adhesive is not an easy operation because appropriate management such as the pasting position and the amount of liquid is required and high attention must be paid. Therefore, since the method according to the present invention includes a relatively easy operation process, the workability during assembly can be improved.

[0023] A method for fixing a terminal module to a case that houses an electronic device according to the present invention is a method for fixing a terminal module to a case that houses an electronic device, wherein the case that houses the electronic device includes a first case having a through-hole formed therein and a cylindrical housing that communicates with the through-hole and protrudes to the outside, and a second case that houses an imaging element, and the first case and the second case are joined together. The terminal module includes a shell that is a cylindrical conductor having a flange portion with a larger diameter on the base end side than on the tip end side, a center contact disposed inside along the central axis of the shell, and an insulating member interposed between the shell and the center contact and holding the center contact. The method includes a step of disposing a thermal adhesive film for joining a plurality of members made of the same material or different materials on the surface of the flange portion on the tip end side; a step of inserting the terminal module into the through-hole from the tip end side to a position where the flange portion is in contact with a flange receiving portion formed around the outer edge of the through-hole on the inner surface side of the first case via the disposed thermal adhesive film; a step of further pressing the terminal module into the housing and press-fitting it into the through-hole after inserting the terminal module into the through-hole; and a step of heating the periphery of the flange receiving portion after the press-fitting.

[0024] With this configuration, in the method for fixing a terminal module to a case that houses an electronic device according to the present invention, a thermal adhesive film is disposed on the surface of the flange portion of the terminal module on the tip end side, the terminal module is inserted into the through-hole and then press-fitted, and the thermal adhesive film sandwiched between the flange portion and the flange receiving portion is heated so that the thermal adhesive film softens, and the terminal module and the first case are adhered and fixed.

[0025] Therefore, compared with the conventional method of wearing a seal member such as an O-ring around the terminal module in advance, forming a locking structure for locking the seal member to the terminal module, deforming the locking structure to fix the seal member, and then inserting and press-fitting the terminal module into the case that houses the electronic device to fix the terminal module to the case that houses the electronic device, the method according to the present invention can reduce the assembly man-hours.

[0026] In addition, since the terminal module and the first case are adhered by the flange portion and the flange receiving portion, liquid will not enter the inside of the case that houses the electronic device through the through hole from the outside of the case that houses the electronic device, or conversely, liquid will not flow out from the inside of the case that houses the electronic device to the outside of the case that houses the electronic device through the through hole, and the case that houses the electronic device has a waterproof function.

[0027] Also, since the thermal adhesive film has no adhesiveness at normal temperature and is easy to position, it is relatively easy to place the thermal adhesive film on the flange portion. Furthermore, after press-fitting the terminal module into the through hole of the case that houses the electronic device, the terminal module can be fixed to the case that houses the electronic device simply by heating the thermal adhesive film, so the operation is relatively easy.

[0028] On the other hand, fixing with a conventional double-sided tape or adhesive is not an easy operation because appropriate management of the pasting position, liquid amount, etc. is required and high attention must be paid. Therefore, since the method according to the present invention includes a relatively easy operation process, the workability during assembly can be improved.

[0029] The fixing structure of a terminal module to a case housing an electronic device according to the present invention is a fixing structure of a terminal module to a case housing an electronic device, wherein the case housing the electronic device has a through hole formed therein, and a first case having a cylindrical housing communicating with the through hole and protruding to the outside, and a second case housing an imaging element, and the first case and the second case are joined to each other. The terminal module includes a shell which is a cylindrical conductor having a flange portion with a larger diameter on the base end side than on the tip end side, a center contact disposed inside along the central axis of the shell, and an insulating member interposed between the shell and the center contact and holding the center contact. The terminal module is regulated by a regulating portion formed on the inner peripheral surface of the housing at the tip end side, and the flange portion and a flange receiving portion formed around the through hole on the inner surface side of the first case are adhered by a thermal adhesive film that joins a plurality of members made of the same material or different materials sandwiched between the flange portion and the flange receiving portion, thereby being fixed to the case housing the electronic device.

[0030] With this configuration, in the fixing structure of the terminal module to the case housing the electronic device according to the present invention, the terminal module and the first case are adhered by the flange portion and the flange receiving portion, so that liquid does not enter from the outside of the case housing the electronic device into the inside of the case housing the electronic device through the through hole, or conversely, liquid does not flow out from the inside of the case housing the electronic device to the outside of the case housing the electronic device through the through hole, and the case housing the electronic device has a waterproof function.

[0031] Further, the terminal module is fixed by the flange portion being fixed to the flange receiving portion by the thermal adhesive film on the base end side and being regulated by the regulating portion formed on the inner peripheral surface of the housing on the tip end side. Therefore, the terminal module is fixed to the case housing the electronic device more firmly and stably than when it is fixed only at one end side of the terminal module.

Effect of the Invention

[0032] According to the present invention, when fixing a terminal module to a case housing an electronic device, a waterproof function can be provided, the number of assembly steps can be reduced, and the workability during assembly can be improved. A method for fixing a terminal module to a case housing an electronic device and a fixing structure for the terminal module to the case housing the electronic device can be provided.

Embodiments for Carrying Out the Invention

[0034] Hereinafter, the camera case 101 according to the present embodiment will be described with reference to FIGS. 1 to 16.

[0035] FIG. 1 is a schematic diagram showing the state before assembly of the camera case 101 according to the present embodiment. In FIG. 1, the X direction is the horizontal direction, the Y direction is the depth direction, and the Z direction is the height direction or the axial direction, and the same applies to FIGS. 2 and subsequent figures. The positive side in the Z direction may be referred to as the upper side or the proximal side, and the negative side may be referred to as the lower side or the distal side.

[0036] (Camera case) As shown in FIG. 1, the camera case 101 includes a front case 102 and a rear case 110. The camera case 101 is joined such that the front case 102 and the rear case 110 face each other, forming a space for accommodating a camera module 103 and the like, which will be described later. The front case 102 and the rear case 110 are joined by, for example, an adhesive, but may also be joined by other mechanical methods or methods such as welding. The camera case 101 constitutes a case for housing an electronic device according to the present invention. The front case 102 constitutes a second case according to the present invention. The rear case 110 constitutes a first case according to the present invention. The electronic device referred to here is a camera or the like (including smartphones, tablet terminals, etc.). In the present embodiment, the camera case 101, which is a camera case for an in-vehicle camera, will be described as an example. However, the camera case 101 is not necessarily a camera case for an in-vehicle camera and may be a case for housing other electronic devices.

[0037] The terminal module 130 is fixed to the camera case 101 by a fixing method described later. By fixing the terminal module 130 to the camera case 101, when the camera case 101 is assembled, the external connector 107 having the cable 107a and the camera module 103 are electrically connected via the terminal module 130.

[0038] (Camera module) The camera module 103 is configured to include a camera substrate 104 and an imaging device 106. The camera module 103 is installed in the accommodation space inside the camera case 101. The camera module 103 images the outside of the camera case 101 through the lens hole formed in the front case 102.

[0039] The camera substrate 104 is, for example, a printed circuit board (PCB), and an imaging device 106 such as a CCD or CMOS is mounted thereon. The camera substrate 104 has a substrate-side connector 105. The camera substrate 104 is electrically connected to the external connector 107 by the substrate-side connector 105 contacting a terminal module 130 described later and the terminal module 130 contacting the external connector 107.

[0040] (Front case) The front case 102 houses the camera module 103 including the camera substrate 104 and the imaging device 106, and constitutes the camera case 101 by being joined to a rear case 110 described later. In the present embodiment, the front case 102 is made of aluminum, but may be made of other metals such as copper, or may be made of resin such as ABS or polycarbonate.

[0041] (Rear case) As shown in FIGS. 2(a) and (b), the rear case 110 has a through hole 115 formed from the rear case surface 111 to the rear case inner surface 112. The rear case 110 has a cylindrical housing 120 described later that communicates with the through hole 115 and protrudes outside the camera case 101. The rear case 110 constitutes the camera case 101 by being joined to the front case 102. In the present embodiment, the rear case 110 is made of aluminum, but may be made of other metals such as copper, or may be made of resin such as ABS or polycarbonate.

[0042] As shown in FIGS. 2(a) and 2(b), the rear case 110 has a rear case surface 111, a rear case inner surface 112, and rear case side surfaces 113a, 113b, 113c, and 113d as outer surfaces. The rear case inner surface 112 is the surface on the inner surface side of the camera case 101. A flange receiving portion 112a is formed around the outer edge of the through hole 115 in the rear case inner surface 112. The flange receiving portion 112a is an annular region that is recessed in the negative Z direction from the rear case inner surface 112. The flange receiving portion 112a is perpendicular to the Z direction and is formed on the XY plane. The heat adhesive film 160, which will be described later, can be disposed on the flange receiving portion 112a.

[0043] Inside the rear case 110, four rear case engaging portions 114a, 114b, 114c, and 114d are formed around the through hole 115. The rear case engaging portions 114a, 114b, 114c, and 114d are adapted to engage with notch engaging portions 148a, 148b, 148c, and 148d of a shell 140, which will be described later. In the present embodiment, four rear case engaging portions and four notch engaging portions are provided, respectively, but the number is not necessarily limited to this, and a larger number or a smaller number may be used.

[0044] Below the rear case surface 111 (in the negative Z direction), a housing 120, which will be described later, is formed so as to protrude outside the camera case 101, and the shell 140 press-fitted into the housing 120 and the external connector 107 can be fitted together.

[0045] (Housing) The housing 120 is a cylindrical member that communicates with the through hole 115 of the rear case 110 and protrudes outside the camera case 101. The housing 120 has a proximal housing portion 121 on the proximal end side (positive Z direction) and a cylindrical portion 122 on the distal end side (negative Z direction). Inside the housing 120, a terminal module 130, which will be described later, is inserted, press-fitted, and fixed.

[0046] The base housing portion 121 is formed on the rear case surface 111 and has a diameter larger than that of the cylindrical portion 122. The cylindrical portion 122 is a cylindrical part formed on the base housing portion 121 and is hollow inside. The terminal module 130 described later can be inserted into the hollow portions inside the base housing portion 121 and the cylindrical portion 122.

[0047] As shown in FIG. 9, on the inner peripheral surface 122a of the cylindrical portion 122, which is the inner surface of the cylindrical portion 122, first restricting portions 123 and second restricting portions 124 are formed to restrict and fix the movements of the first locking portion 146 and the second locking portion 147 of the shell 140 described later. The first restricting portion 123 is formed closer to the base end side (positive Z direction) than the second restricting portion 124.

[0048] The first restricting portion 123 is a portion where a radially concave portion is formed on the inner peripheral surface 122a of the cylindrical portion 122 when advancing in the positive Z-axis direction from the second restricting portion 124 described later along the inner peripheral surface 122a of the cylindrical portion 122. The inner diameter of the concave portion forming the first restricting portion 123 is smaller than the inner diameter of the stepped portion formed by the second restricting portion 124. When the first locking portion 146 of the shell 140 is press-fitted into the housing 120 due to the formation of the concave portion, the first locking portion 146 is caught by the first restricting portion 123, and the axial movement is restricted. That is, the first restricting portion 123 determines the press-fitting position when the shell 140 is press-fitted into the housing 120.

[0049] The second restricting portion 124 is a portion where the inner diameter of the inner peripheral surface 122a of the cylindrical portion 122 is locally reduced and a step is formed when advancing in the positive Z-axis direction from the tip side along the inner peripheral surface 122a of the cylindrical portion 122, and is formed on the tip side in the axial direction of the inner peripheral surface 122a of the cylindrical portion 122 compared to the first restricting portion 123. The inner diameter of the stepped portion formed by the second restricting portion 124 is larger than the inner diameter of the concave portion formed by the first restricting portion 123. When the second locking portion 147 of the shell 140 is press-fitted into the housing 120 and then caulked, the second locking portion 147 is caught by the second restricting portion 124, and the axial movement is restricted. That is, the second restricting portion 124 determines the position when the shell 140 is caulked into the housing 120.

[0050] In this way, the terminal module 130 is restricted by the first restricting portion 123 and the second restricting portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 on the tip side, and as will be described later, the base end flange portion 142 is fixed to the flange receiving portion 112a by the heat adhesive film 160 on the base end side, so that it is fixed to the camera case 101. Therefore, the terminal module 130 is fixed to the camera case 101 more firmly and stably than when it is fixed only at one end side of the terminal module 130.

[0051] (Terminal module) As shown in FIGS. 3(a), (b) and 9, the terminal module 130 includes a shell 140, a center contact 131, and an insulator 135. After the terminal module 130 is inserted into the through hole 115 of the rear case 110, it is pressed axially toward the inside of the housing 120, press-fitted into the through hole 115 and the inside of the housing 120, and further heated to be fixed to the camera case 101.

[0052] The terminal module 130 contacts the external connector 107 on the tip side (negative Z direction) and contacts the board-side connector 105 of the camera board 104 on the base end side, so that the camera board 104 and the external connector 107 can be electrically connected.

[0053] (Shell) FIG. 3 shows the shell 140 according to the present embodiment. FIG. 3(a) is a perspective view seen from the upper side (positive Z direction), and FIG. 3(b) is a perspective view seen from the lower side (negative Z direction). The shell 140 is made of a metal such as zinc die-cast, for example, and is a conductor having a cylindrical portion. The shell 140 has a base end shell portion 141 on the base end side (positive Z direction) and a tip shell portion 145 on the tip side (negative Z direction). The shell 140 constitutes the shell according to the present invention.

[0054] As shown in FIG. 9, inside the shell 140, there are provided a central contact 131 (described later) along the central axis, and an insulator 135 (described later) interposed between the shell 140 and the central contact 131 to hold the central contact 131.

[0055] The base end shell portion 141 has a base end flange portion 142, a base end cylindrical portion 143, and base end pieces 144a, 144b, 144c, 144d. The base end flange portion 142 is connected to the tip end shell portion 145 on the tip end side as shown in FIGS. 3(a) and 3(b), and has a larger diameter than the tip end shell portion 145. The base end flange portion 142 constitutes the flange portion according to the present invention.

[0056] The surface on the base end side of the base end flange portion 142 is referred to as the upper surface 142a of the base end flange portion, and the surface on the tip end side is referred to as the lower surface 142b of the base end flange portion. As shown in FIG. 11, when the terminal module 130 is inserted into and press-fitted into the through hole 115, the lower surface 142b of the base end flange portion contacts the flange receiving portion 112a via a heat adhesive film 160 (described later).

[0057] The base end cylindrical portion 143 is a cylindrical portion connected to the base end flange portion 142 on the base end side. The base end cylindrical portion 143 is capable of being fitted with the board-side connector 105 together with the base end pieces 144a, 144b, 144c, 144d (described later).

[0058] The base end pieces 144a, 144b, 144c, 144d are four metal pieces connected to the base end cylindrical portion 143 on the base end side. As shown in FIG. 3(a), in a state where no load is applied from the outside, they are bent outward from the base end cylindrical portion 143 and spread. When the terminal module 130 is fitted with the board-side connector 105, the base end pieces 144a, 144b, 144c, 144d are further bent outward and deformed by applying a load in the positive axial direction.

[0059] The distal shell portion 145 is a portion that is connected to the base flange portion 142 of the base shell portion 141 on the distal end side. The distal shell portion 145 has notch engaging portions 148a, 148b, 148c, 148d and a distal cylindrical portion 149. The notch engaging portions 148a, 148b, 148c, 148d are formed in four on the lower surface of the base flange portion 142, which is the lower surface side of the base flange portion 142, i.e., on the base flange portion lower surface 142b. In the present embodiment, four notch engaging portions are provided, but the number is not necessarily limited to this. Depending on the number of the rear case engaging portions, a larger number or a smaller number may be used.

[0060] The notch engaging portions 148a, 148b, 148c, 148d are formed by notching a cylindrical portion having a diameter smaller than that of the base flange portion 142 as shown in FIG. 3(a). The notch engaging portions 148a, 148b, 148c, 148d are adapted to engage with the rear case engaging portions 114a, 114b, 114c, 114d, respectively, when the terminal module 130 is inserted into and press-fitted into the through hole 115 of the rear case 110.

[0061] The distal cylindrical portion 149 is a cylindrical portion that is connected to the notch engaging portions 148a, 148b, 148c, 148d on the distal end side. A first locking portion 146 and a second locking portion 147 with a locally enlarged diameter are formed on the outer peripheral surface of the distal cylindrical portion 149. The first locking portion 146 is formed on the base end side (positive Z direction) of the second locking portion 147.

[0062] As shown in FIG. 11, when the terminal module 130 is press-fitted into the housing 120 in the negative Z direction, the first locking portion 146 is pushed in and deformed, and is caught by the first regulating portion 123 of the housing 120, thereby restricting the axial movement of the terminal module 130.

[0063] As shown in FIG. 13, when the second locking portion 147 is caulked after the terminal module 130 is press-fitted into the housing 120 in the negative Z direction, it is pushed in and deformed, and is caught by the second regulating portion 124 of the housing 120, thereby restricting the axial movement of the terminal module 130.

[0064] In this way, the terminal module 130 is restricted by the first restricting portion 123 and the second restricting portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 on the tip side, and as will be described later, the base end flange portion 142 is fixed to the flange receiving portion 112a by the heat adhesive film 160 on the base end side, thereby being fixed to the camera case 101. Therefore, the terminal module 130 is more firmly and stably fixed to the camera case 101 than when it is fixed only at one end side of the terminal module 130.

[0065] (Insulator) The insulator 135 is an insulating member interposed between the shell 140 and the center contact 131, which will be described later, and holds the center contact 131. The insulator 135 is made of a resin such as polyamide, for example, and insulates the center contact 131 from the outside. The insulator 135 constitutes the insulating member according to the present invention.

[0066] As shown in FIGS. 11, 13, etc., a through hole 135b for holding the center contact 131 is formed inside the insulator 135 along the central axis in the Z direction. A plurality of insulator engaging portions 135a that engage with the engaging pieces 131a of the center contact 131, which will be described later, are formed on the inner peripheral surface of the through hole 135b. By the engagement of the insulator engaging portion 135a with the engaging piece 131a, the center contact 131 is held by the insulator 135. The insulator 135 is fixed to the shell 140 by fixing means (not shown).

[0067] (Center contact) The center contact 131 is disposed inside the insulator 135 inside the shell 140 along the central axis of the shell 140. The center contact 131 contacts the board-side connector 105 on the base end side (the positive direction in the Z direction) and contacts and conducts with the external connector 107 on the tip side (the negative direction in the Z direction). The center contact 131 is made of, for example, a copper alloy, but may be made of other metals.

[0068] As shown in FIGS. 11, 13, etc., a plurality of engaging pieces 131a protruding radially are formed on the central contact 131. By engaging the engaging piece 131a with the insulator engaging portion 135a, the central contact 131 is held by the insulator 135.

[0069] (Thermal Adhesive Film) The thermal adhesive film 160 is a film that joins a plurality of members made of the same material or different materials by using heat. The thermal adhesive film 160 can be applied to difficult-to-bond resins such as polypropylene and polyethylene, and metal materials. The thermal adhesive film 160 adheres and fixes the flange receiving portion 112a of the rear case 110 and the base end flange portion 142 of the terminal module 130. As shown in FIG. 4, the thermal adhesive film 160 has an annular shape and is sized to be disposed on the flange receiving portion 112a. In this embodiment, a thermal adhesive film is used, but as a similar bonding means, a thermocompression bonding film or a thermocompression bonding sheet may be used.

[0070] The thermal adhesive film 160 contains a thermoplastic resin as a blending component, and has almost no adhesiveness at normal temperature. However, for example, by heating to 150° C. or higher, a plurality of members can be bonded. The heating temperature may be changed according to the physical properties of the thermal adhesive film 160. Heating of the thermal adhesive film 160 is performed using an induction heating device 161 after performing the press-fitting process of the terminal module 130 described later. The induction heating device 161 may be a known induction heating device and can heat the target member non-contact.

[0071] As the thermoplastic resin, it is desirable to use any of resins such as polyolefin-based resins, olefin-based thermoplastic elastomers, styrene-based thermoplastic elastomers, polyamide resins, polyvinyl acetate resins, polyacetal resins, polycarbonate-based resins, polyacrylic-based resins, polyamide-based resins, polyimide-based resins, polyvinyl acetate-based resins, phenoxy-based resins, and polyester-based resins.

[0072] In this way, the terminal module 130 is restricted by the first restricting portion 123 and the second restricting portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 on the tip side, and on the base end side, the base end flange portion 142 is fixed to the flange receiving portion 112a by the heat adhesive film 160, thereby being fixed to the camera case 101. Therefore, the terminal module 130 is fixed to the camera case 101 more firmly and stably than when it is fixed only on one end side of the terminal module 130.

[0073] Normally, a heat adhesive film is used for the purpose of adhering members. However, as a result of repeated tests and research, the applicant has found that using the heat adhesive film 160 as a means of adhering the rear case 110 and the terminal module 130 has not only the following characteristics (1)-(4) in addition to adhesion.

[0074] (1) Waterproof function The applicant has found that by using the heat adhesive film 160 to fix the terminal module 130 to the camera case 101 described later, liquid will not enter the inside of the camera case 101 from the outside of the camera case 101 through the through hole 115, or conversely, liquid will not flow out of the inside of the camera case 101 through the through hole 115 to the outside of the camera case 101, and there is a waterproof effect on the camera case 101. In addition, it has been found that this waterproof effect is equal to or better than the case where a sealing member such as an O-ring is worn around the terminal module 130 without using the heat adhesive film 160. Therefore, in this embodiment, a sealing member such as an O-ring is not worn around the terminal module 130.

[0075] (2) Man-hour reduction By using the thermal adhesive film 160 to fix the terminal module 130 to the camera case 101 described below, it becomes unnecessary to wear a sealing member such as an O-ring around the terminal module 130 as described above. For example, when using an O-ring, a locking structure for locking the O-ring to the terminal module 130 is formed, the O-ring is fixed by deforming the locking structure, and then the terminal module 130 is inserted into the camera case 101 and press-fitted to fix the terminal module 130 to the camera case 101. Therefore, when using the thermal adhesive film 160, the man-hours for assembling the camera case 101 can be reduced.

[0076] (3) Workability The thermal adhesive film 160 has no adhesiveness at room temperature and is easy to position. Therefore, it is relatively easy to place the thermal adhesive film 160 on the flange receiving portion 112a. Furthermore, after press-fitting the terminal module 130 into the through hole 115 of the camera case 101, the terminal module 130 can be fixed to the camera case 101 simply by heating the thermal adhesive film 160, so the operation is relatively easy.

[0077] (4) Fixing function The press-fitting of the terminal module 130 in this embodiment is performed by the first regulating portion 123 regulating the first locking portion 146 as shown in FIG. 11. When the press-fitting is performed at one location and the terminal module 130 is fixed to the camera case 101, the terminal module 130, which is formed to be long in the Z direction as a whole, is fixed by only a certain part that is press-fitted in the Z direction. Therefore, when a force in the XY direction is applied to the terminal module 130, a large force is applied to a portion away from the fixed portion (for example, the protruding end portion on the base end side of the center contact 131) due to the lever principle, and displacement in the XY direction is likely to occur. Thus, fixing only by press-fitting is strong in the Z direction, but not necessarily strong in the XY direction. However, in this embodiment, in addition to press-fitting, the terminal module 130 is fixed to the camera case 101 by using a thermally adhesive film 160 to bond the flange receiving portion 112a and the base end flange portion 142, which are surfaces perpendicular to the Z direction. By fixing in a plane perpendicular to the Z axis at a position away from the press-fitted portion in the Z-axis direction in addition to press-fitting in this way, fixing is performed at two locations in the Z-axis direction (the press-fitting location and the thermally adhesive location), and since one of them (the thermally adhesive location) is fixing in a plane perpendicular to the Z axis, strong fixing can be realized even with respect to the force applied in the XY direction.

[0078] Furthermore, for example, when the camera case 101 is made of a metal material or resin different from that of the shell 140, since the linear expansion coefficient is different from that of the metal shell 140, when an external load or thermal load is applied to the camera case 101, displacement may occur due to expansion or the like at the contact surface (the flange receiving portion 112a and the base end flange portion 142) between the camera case 101 and the terminal module 130. However, by using the thermally adhesive film 160 to bond the terminal module 130 to the camera case 101 at the flange receiving portion 112a and the base end flange portion 142, even when an external load or thermal load is applied to the camera case 101, displacement between the camera case 101 and the terminal module 130 is less likely to occur.

[0079] <Method for fixing the terminal module to the camera case> Hereinafter, a method of fixing a terminal module to the camera case according to the present embodiment (hereinafter, simply referred to as the fixing method) will be described with reference to FIGS. 5 to 14. The fixing method according to the present embodiment includes a thermal adhesive film arrangement step, a terminal module insertion step, a press-fitting step, a caulking step, and a heating step.

[0080] <Thermal adhesive film arrangement step> FIG. 5 is an exploded perspective view showing a state before fixing the terminal module 130 to the camera case 101. In the thermal adhesive film arrangement step, as shown in FIG. 6, the thermal adhesive film 160 is arranged on the flange receiving portion 112a of the rear case 110. Since the thermal adhesive film 160 has no adhesiveness at room temperature, the position adjustment of the thermal adhesive film 160 can be easily performed.

[0081] <Terminal module insertion step> After completion of the thermal adhesive film arrangement step, the terminal module 130 is inserted axially from the tip side into the through hole 115 and the housing 120 communicating with the through hole 115. FIG. 7 is a perspective view showing a state where the terminal module 130 is inserted into the through hole 115 and the housing 120 of the rear case 110, FIG. 8 is a top view thereof, and FIG. 9 is a cross-sectional view taken along the line A-A in FIG. 8. FIGS. 7 to 9 show a state during the insertion of the terminal module 130. As shown in FIG. 9, the base end flange portion 142 is not in contact with the thermal adhesive film 160 on the flange receiving portion 112a, but is inserted to a position where the base end flange portion 142 is in contact with the flange receiving portion 112 via the thermal adhesive film 160. At the completion of insertion, since heating has not been performed yet, the base end flange portion 142 and the flange receiving portion 112a are not adhered by the thermal adhesive film 160, and the base end flange portion 142 can be easily separated from the flange receiving portion 112a.

[0082] <Press-fitting step> After the completion of the terminal module insertion process, the terminal module 130 is pressed toward the through hole 115 and into the housing 120 and press-fitted into the through hole 115 and the housing 120. When performing the press-fitting, a known press-fitting jig or device (not shown) is used. FIG. 10 is a perspective view showing a state where the terminal module 130 is press-fitted into the through hole 115 of the rear case 110 and the housing, and FIG. 11 is a cross-sectional view of a cross section at the same position as the A-A cross section in FIG. 8. As shown in FIG. 11, when the first locking portion 146 of the shell 140 is press-fitted into the housing 120, the first locking portion 146 is caught by the first restricting portion 123, and the axial movement is restricted. After the completion of the press-fitting, as will be described later, the camera case 101 and the terminal module 130 are more firmly fixed by caulking or the heat-bonding film 160. However, even in the state where the press-fitting is completed, the camera case 101 and the terminal module 130 are fixed to such an extent that they do not easily separate.

[0083] <Caulking Process> After the completion of the press-fitting process, the terminal module 130 is pressed toward the through hole 115 and into the housing 120 and caulked. When performing the caulking, a known caulking jig or device (not shown) is used. FIG. 12 is a perspective view showing a state where the terminal module 130 is caulked after being press-fitted into the through hole 115 of the rear case 110 and the housing 120, and FIG. 13 is a cross-sectional view of a cross section at the same position as the A-A cross section in FIG. 8. As shown in FIG. 13, when the terminal module 130 is caulked, the second locking portion 147 is caught by the second restricting portion 124, and the axial movement is restricted. Even in the state where the terminal module 130 is caulked, the state where the first locking portion 146 at the time of press-fitting is caught by the first restricting portion 123 is maintained. Therefore, in the state where the caulking process is completed, the camera case 101 and the terminal module 130 are fixed more firmly than in the state where the press-fitting process is completed.

[0084] <Heating Process> After the clamping process is completed, by heating the periphery of the flange receiving portion 112a, the heat adhesive film 160 sandwiched between the flange receiving portion 112a and the base end flange portion 142 is heated, and the flange receiving portion 112a and the base end flange portion 142 are adhered. FIG. 14 is a cross-sectional view at the same position as the A-A cross-section in FIG. 8 showing a state in which the heat adhesive film 160 is being heated after the terminal module is clamped to the through hole 115 and the housing 120. The heating is performed using an induction heating device 161. The induction heating device 161 may be a known induction heating device and is capable of heating the target member in a non-contact manner. The heating temperature may be determined according to the physical properties of the heat adhesive film 160. For example, the heating temperature is 150° C. or higher.

[0085] When the heating process is completed, due to the adhesive function of the heat adhesive film 160, the flange receiving portion 112a and the base end flange portion 142 can be adhered and fixed, and water can also be prevented from entering through the gap between the flange receiving portion 112a and the base end flange portion 142.

[0086] <Modification Example of the Method for Fixing the Terminal Module to the Camera Case> Hereinafter, a modification example of the method for fixing the terminal module to the above-described camera case will be described.

[0087] <Modification Example 1> FIG. 15 is a cross-sectional view at the same position as the A-A cross-section in FIG. 8 showing a state in which the terminal module 130 is being clamped to the through hole 115 and the housing 120 of the rear case 110 while the heat adhesive film 160 is being heated. In this modification example, instead of performing the heating process after the clamping process as described above, the clamping process and the heating process are performed simultaneously. By performing the clamping of the terminal module 130 and the heating of the heat adhesive film 160 simultaneously, the working time can be shortened compared to the case where they are performed separately.

[0088] <Modification Example 2> FIG. 16 is a perspective view showing a state in which a thermal adhesive film 160 is disposed on the lower surface 142b of the base flange portion of the base flange portion 142. In this modification, unlike the above-described thermal adhesive film disposition step, the thermal adhesive film 160 is disposed on the lower surface 142b of the base flange portion of the base flange portion 142 instead of the flange receiving portion 112a. If necessary, the thermal adhesive film 160 may be heated and adhered to the base flange portion 142. The terminal module insertion step, press-fitting step, caulking step, and heating step after the thermal adhesive film disposition step are the same as the above-described methods.

[0089] <Another modification> As another modification, when the fixing strength of the camera case 101 and the terminal module 130 is sufficient by press-fitting, the caulking step may not be performed, and the heating step may be performed after the press-fitting step. Alternatively, the heating step may be performed while performing the press-fitting step.

[0090] As described above, in the method of fixing the terminal module 130 to the camera case 101 according to the present embodiment, the camera case 101 includes a rear case 110 having a through hole 115 formed therein and a cylindrical housing 120 that communicates with the through hole 115 and protrudes to the outside, and a front case 102 that houses the imaging element 106. The rear case 110 and the front case 102 are joined to each other. The terminal module 130 includes a shell 140 that is a cylindrical conductor having a base flange portion 142 whose diameter is larger on the base end side than on the tip end side, a center contact 131 disposed inside along the central axis of the shell 140, and an insulator 135 that is interposed between the shell 140 and the center contact 131 and holds the center contact 131.

[0091] The method of fixing the terminal module 130 to the camera case 101 according to this embodiment includes a step of disposing a thermal adhesive film 160, which joins a plurality of members made of the same material or different materials, around the outer edge of the through-hole 115 on the inner surface side of the rear case 110 at a flange receiving portion 112a; a step of inserting the terminal module 130 into the through-hole 115 from the tip side until the base end flange portion 142 contacts the flange receiving portion 112a via the thermal adhesive film 160; a step of further pressing the terminal module 130 toward the inside of the housing 120 and press-fitting it into the through-hole 115 after inserting the terminal module 130 into the through-hole 115; a step of pressing and caulking the terminal module 130 toward the inside of the through-hole 115 and the housing 120 after press-fitting; and a step of heating the periphery of the flange receiving portion 112a after caulking. In the step of press-fitting the terminal module 130 into the through-hole 115, the press-fitting position of the terminal module 130 is restricted by a first restricting portion 123 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 by a first locking portion 146 on the tip side of the terminal module 130. In the step of pressing and caulking the terminal module 130 toward the inside of the through-hole 115 and the housing 120 after press-fitting, the caulking position of the terminal module 130 is restricted by a second restricting portion formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 by a second locking portion 147 on the tip side of the terminal module 130.

[0092] With this configuration, the method of fixing the terminal module 130 to the camera case 101 according to this embodiment is to dispose the thermal adhesive film 160 at the flange receiving portion 112a of the rear case 110, insert the terminal module 130 into the through-hole 115 and then press-fit it, and heat the thermal adhesive film 160 sandwiched between the base end flange portion 142 and the flange receiving portion 112a, so that the thermal adhesive film 160 softens, and the terminal module 130 and the rear case 110 are adhered and fixed.

[0093] Therefore, compared with the conventional method of wearing a sealing member such as an O-ring around a terminal module in advance, forming a locking structure for locking the sealing member to the terminal module, deforming the locking structure to fix the sealing member, and then inserting and press-fitting the terminal module into a camera case to fix the terminal module to the camera case, the method according to the present embodiment can reduce the assembly man-hours.

[0094] In addition, since the terminal module 130 and the rear case 110 are adhered by the base end flange portion 142 and the flange receiving portion 112a, liquid does not enter the inside of the camera case 101 through the through hole 115 from the outside of the camera case 101, or conversely, liquid does not flow out from the inside of the camera case 101 to the outside of the camera case 101 through the through hole 115, and the camera case 101 has a waterproof function.

[0095] Also, the thermal adhesive film 160 has no adhesiveness at room temperature and is easy to position, so it is relatively easy to arrange the thermal adhesive film 160 on the flange receiving portion 112a. Furthermore, after press-fitting the terminal module 130 into the through hole 115 of the camera case 101, the terminal module 130 can be fixed to the camera case 101 only by heating the thermal adhesive film 160, so the operation is relatively easy.

[0096] On the other hand, fixing with a conventional double-sided tape or adhesive is not an easy operation because appropriate management of the pasting position, liquid amount, etc. is required and high attention needs to be paid. Therefore, since the method according to the present embodiment includes a relatively easy operation process, the workability during assembly can be improved.

[0097] The terminal module 130 is fixed to the flange receiving portion 112a by the heat adhesive film 160 at the base end side with the base end flange portion 142, and is fixed by being regulated by the first regulating portion 123 and the second regulating portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 at the tip end side. Therefore, the terminal module 130 is fixed to the camera case 101 more firmly and stably than when it is fixed only at one end side of the terminal module 130.

[0098] The method of fixing the terminal module 130 to the camera case 101 according to the present embodiment may include a step of heating the periphery of the flange receiving portion 112a while pressing the terminal module 130 into the through hole 115 by further pressing the terminal module 130 into the housing 120 after inserting the terminal module 130 into the through hole 115.

[0099] With this configuration, the method of fixing the terminal module 130 to the camera case 101 according to the present embodiment can shorten the working time compared to the case of performing them separately by performing the press-fitting of the terminal module 130 and the heating of the heat adhesive film 160 simultaneously.

[0100] The method of fixing the terminal module 130 to the camera case 101 according to the present embodiment may include a step of disposing a heat adhesive film 160 that joins a plurality of members made of the same material or different materials on the lower surface 142b of the base end flange portion, which is the surface on the tip end side of the base end flange portion 142.

[0101] The fixing structure of the terminal module 130 to the camera case 101 according to this embodiment is a fixing structure of the terminal module 130 to the camera case 101. The camera case 101 includes a rear case 110 having a through hole 115 formed therein and a cylindrical housing 120 that communicates with the through hole 115 and protrudes to the outside, and a front case 102 that houses the imaging element 106. The rear case 110 and the front case 102 are joined together. The terminal module 130 includes a shell 140 that is a cylindrical conductor having a base end flange portion 142 with a larger diameter on the base end side than on the tip end side, a center contact 131 disposed inside along the central axis of the shell 140, and an insulator 135 that is interposed between the shell 140 and the center contact 131 and holds the center contact 131. The terminal module 130 is restricted by a first restricting portion 123 and a second restricting portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 on the tip end side, and the base end flange portion 142 and a flange receiving portion 112a formed around the through hole 115 on the inner surface side of the rear case 110 are adhered by a thermal adhesive film 160 that joins a plurality of members made of the same material or different materials sandwiched between the base end flange portion 142 and the flange receiving portion 112a, thereby being fixed to the camera case 101.

[0102] With this configuration, in the fixing structure of the terminal module 130 to the camera case 101 according to this embodiment, the terminal module 130 and the rear case 110 are adhered by the base end flange portion 142 and the flange receiving portion 112a, so that liquid does not enter the inside of the camera case 101 through the through hole 115 from the outside of the camera case 101, or conversely, liquid does not flow out of the inside of the camera case 101 through the through hole 115 to the outside of the camera case 101, and the camera case 101 has a waterproof function.

[0103] Further, in the terminal module 130, a base end flange portion 142 is fixed to a flange receiving portion 112a by a heat adhesive film 160 on the base end side, and a first locking portion 146 and a second locking portion 147 are regulated by a first regulating portion 123 and a second regulating portion 124 formed on the inner peripheral surface 122a of the cylindrical portion of the housing 120 on the tip end side, thereby being fixed. Therefore, the terminal module 130 is fixed to the camera case 101 more firmly and stably than in the case where it is fixed only on one end side of the terminal module.

[0104] As described above, the method for fixing a terminal module to a case for housing an electronic device according to the present invention and the fixing structure of the terminal module to the case for housing the electronic device have the effects of providing a waterproof function, reducing the number of assembly steps, and improving the workability during assembly when fixing the terminal module to the case for housing the electronic device, and are useful for the method for fixing a terminal module to the case for housing the electronic device and the entire fixing structure of the terminal module to the case for housing the electronic device.
