Description

  The present invention relates to an electronic component and a method of manufacturing the electronic component, and more particularly to an electronic component used in an imaging device or the like and a method of manufacturing the electronic component.

  2. Description of the Related Art Small-sized electronic components in which a circuit board is built in a housing are widely used, such as imaging devices such as in-vehicle cameras and surveillance cameras. For example, the electronic component is embedded in the housing while connecting the inner terminal portion connected to the circuit board housed inside the housing, the outer terminal portion connected to the external device, the inner terminal portion and the outer terminal portion The terminal which has a relay part is provided (for example, refer patent document 1: Unexamined-Japanese-Patent No. 2005-347243).

  As a terminal provided in such an electronic component, there may be a pin terminal in which the inner terminal portion, the relay portion, and the outer terminal portion have a single linear shape as in the patent document. However, depending on the arrangement of the connector mounted on the circuit board connected to the inner terminal portion and the arrangement of the external device connected to the outer terminal portion, the inner terminal portion and the outer terminal portion are not arranged on one axis. They may be arranged offset from one another. In this case, such an arrangement can be coped with by forming the relay portion in a cranked bent shape.

Unexamined-Japanese-Patent No. 2005-347243, Paragraph 0081, 0085, FIG. 3, FIG.

  However, when such a bent-shaped terminal is used, the terminal installed in the cavity of the mold is displaced when the mold is clamped or when the molten resin flows into the cavity when integrally molded with the housing. The terminals may be broken, or the terminals may be integrally formed with the housing due to deviation from the normal arrangement that should be originally installed in the housing.

  The present invention is made on the background of the prior art as described above. An object of the present invention is to prevent displacement of a terminal when the terminal is integrally formed with a housing.

  In order to achieve the above object, the present invention is configured to have the following features.

  That is, the present invention relates to a housing having a first connection portion, a second connection portion, and a partition that separates the first connection portion from the second connection portion, and the first connection portion. A first contact portion to be disposed, a second contact portion to be disposed to the second connection portion, and a relay portion to connect the first contact portion and the second contact portion and to be disposed on the partition wall In the electronic component including the terminal having the housing, the housing is formed as an integral molded body including the terminal, the relay portion is held by a molding jig, and the first contact portion and the second contact portion are formed. It has a held part which controls change of physical relationship with a contact part of the above.

  According to the present invention, the relay portion of the terminal is provided with the held portion that can be held by the forming jig. For this reason, by holding the held portion by the molding jig at the time of molding the housing, the integral including the terminal while maintaining the first contact portion and the second contact portion of the terminal in an appropriate positional relationship. The housing can be molded as a molded body. And since the held portion is held by the molding jig and the terminals do not shift, it is possible to prevent the terminals from being inadvertently moved and damaged when the housing and the terminals are integrally molded. it can.

  The held portion can be configured as an insertion hole through which the forming jig is inserted. In particular, the relay portion has an insertion hole through which a forming jig is inserted as a held portion which suppresses a change in the positional relationship between the first contact portion and the second contact portion, and the terminal is It can be constituted so that it may be connected to the part in which the penetration hole was formed, and may have a receiving part which receives the jig for molding inserted into the penetration hole. For example, the receiving portion is formed on the opposite surface of the first contact portion.

  According to the present invention, the held portion can be configured by the insertion hole which can be easily formed. For the insertion hole, it is only necessary to form the insertion hole by punching in the relay portion, so it is not necessary to separately form a dedicated portion for gripping by a molding jig such as a knob portion, for example, and design and manufacture are easier It is. Further, according to the present invention, the positional relationship between the first contact portion and the second contact portion of the terminal can be appropriately maintained by a simple method of inserting the forming jig into the insertion hole. In addition, in the combination of the insertion hole and the forming jig, the movement of the terminal in any direction other than the inserting and removing directions of the forming jig can be easily and surely stopped. Therefore, when the housing and the terminal are integrally molded, it is possible to more reliably prevent the terminal from moving carelessly and being damaged.

  The held portion may be configured to have a widened portion that protrudes to the outside of the insertion hole.

  When the insertion hole is formed, stress concentration is likely to occur around it, and the structural strength is reduced around the insertion hole where the metal material constituting the terminal is lacking. However, according to the present invention, since the held portion has the widened portion outside the insertion hole, the periphery of the insertion hole can be reinforced by the widened portion. Therefore, the strength reduction of the terminal resulting from having provided the penetration hole can be offset. In addition, when the insertion hole is formed, the conduction cross-sectional area of the terminal portion including the insertion hole decreases, so the allowable current value affected by the cross-sectional area also decreases. However, according to the present invention, since the held portion has the widened portion outside the insertion hole, the conduction cross-sectional area can be secured, and the allowable current value can be set high. From the above, according to the present invention, the application range of the electronic component can be expanded.

  The housing may be configured to have a seal portion in which one end is opened toward the first contact portion and the other end is filled with a waterproof material in a through hole opened to the held portion.

  During molding of the housing, the boundary between the terminal portion in contact with the mold and the molding jig and the non-contacting terminal portion between the mold and the molding jig is exposed as the boundary between the terminal and the housing after molding. Do. When a minute gap is generated at the boundary between the terminal and the housing, when the electronic component is used in a wet area, water may infiltrate from the boundary due to capillary action. However, according to the present invention, since the housing has the seal portion in which the through hole is filled with the waterproof material, moisture infiltrates from the boundary between the terminal and the housing in the through hole formed by the forming jig at the time of forming. Can be prevented.

  The first connection portion has a concave portion communicating with the other end of the through hole, and the seal portion is a hole filling portion in which the waterproof material is filled in the through hole, and the waterproof portion in the concave portion It can be configured to have a recess filling portion filled with a material.

  According to the present invention, since the seal portion waterproofs not only the hole filling portion filling the through hole but also the recess itself communicating with the through hole, the terminal disposed in the recess depending on the thickness of the seal portion The part and the boundary between the terminal and the housing can be isolated from the outside. Therefore, it is possible to more reliably prevent the infiltration of water from the boundary between the terminal and the housing.

  Another object of the present invention, which achieves the above object, is a housing having a first connecting portion, a second connecting portion, and a partition separating the first connecting portion and the second connecting portion; The partition wall connecting the first contact portion disposed in the first connection portion, the second contact portion disposed in the second connection portion, the first contact portion and the second contact portion Method of manufacturing an electronic component including a terminal having a relay portion disposed in the housing, the terminal being installed in a cavity of a mold for molding the housing, and a held portion provided in the relay portion by a molding jig After fixing at a predetermined position of the cavity, a resin material is injected into the cavity to mold the housing as an integral molded body including the terminal.

  According to the present invention, since the held portion provided in the relay portion of the terminal is fixed at a predetermined position of the cavity by the forming jig, the first contact portion and the second contact portion of the terminal are appropriately formed. The housing and the terminal can be integrally molded while keeping the positional relationship. In particular, the positional relationship between the first contact portion and the second contact portion, which is likely to change during attachment to the mold, etc., when the terminal has a relay portion, the held portion It is appropriately maintained by being held by the molding jig. Therefore, when the terminal is fixed to the cavity, the mold is closed, the resin material is injected, and when the housing and the terminal are integrally molded, the terminal is prevented from moving inadvertently and being damaged. be able to. The relay portion has an insertion hole through which a forming jig is inserted as a held portion which suppresses a change in the positional relationship between the first contact portion and the second contact portion, and the terminal is inserted into the insertion portion. It can also be configured to have a receiving portion that is connected to the portion where the hole is formed and that receives the forming jig that is inserted into the insertion hole. In this case, the forming jig is inserted into the insertion hole which is the held portion provided in the relay portion, and is in contact with the receiving portion provided on the terminal connected to the portion where the insertion hole is formed. By doing this, it is possible to easily and reliably stop the movement of the terminal other than the insertion and removal direction of the forming jig. Therefore, when the housing and the terminal are integrally molded, it is possible to more reliably prevent the terminal from moving carelessly and being damaged.

  According to the present invention, since it is possible to prevent unnecessary displacement of the terminal when the terminal is integrally molded with the housing, it is possible to realize a high quality electronic component having a housing in which the terminal is appropriately molded integrally.

  Hereinafter, an embodiment of the "electronic component" of the present invention will be described with reference to the drawings. In the following embodiment, an example in which the “electronic component” of the present invention is applied to a housing 1 provided in a camera module will be described. However, the "electronic component" of the present invention is not limited to the housing 1 for a camera module.

  The terms "first" and "second" described in the specification and the claims are used to distinguish different components of the invention, and to show a specific order or superiority. It is not used. In the present specification and claims, for convenience, as shown in FIG. 1 and the like, the longitudinal direction (width direction, left and right direction) of the housing 1 is X direction, short direction (front side-depth direction, front and back direction) Will be described as Y direction, and height direction (vertical direction) as Z direction. The side of the external device connected to the camera module is the upper side, and the side of the circuit board or the like housed inside the camera module is the lower side. However, they do not limit the use of the camera module and the housing 1 or the like.

The camera module

  The camera module is, for example, a component of an on-vehicle camera mounted on a car or the like. The camera module includes a housing 1, an imaging component case (not shown), and a harness component (not shown). Among these components, the imaging component case includes an optical component such as a lens unit and an imaging component, and is configured in a box shape having a bottom wall. The imaging component case is fixed to the side of the housing 1 shown in FIG. In addition, the harness component is configured to function as an external conductor that connects the housing 1 to an external device (not shown). The harness component is fitted and connected to the side opposite to the imaging component case in the housing 1, that is, the external conductor connection portion 11 described later.

Housing 1

  The housing 1 is formed of an insulating hard resin, and is an integral molded body including a terminal 2 for conductively connecting an imaging component and an external device. The housing 1 is formed in an L shape extending in the X direction and the Z direction in a front view, as shown in FIG. 4 and the like. The housing 1 includes a body portion 10 as a "first connection portion", an outer conductor connection portion 11 as a "second connection portion", and a partition 12 separating the body portion 10 and the outer conductor connection portion 11 Have.

  As shown in FIG. 1, the main body portion 10 is formed in a square flat plate shape extending in the XY plane. The main body 10 has an upper surface 10a on the upper side in the height direction (see FIGS. 1 and 4) and a lower surface 10b on the lower side (see FIGS. 2 and 4). At the center of the upper surface 10a, a recessed portion 10c that is recessed downward in the height direction is formed (see FIGS. 1 and 4). On the lower surface 10b of the main body portion 10, a protrusion 10d is formed whose inner peripheral side protrudes downward in the height direction with respect to the outer peripheral side (see FIGS. 2 and 4).

  The outer conductor connection portion 11 is formed as a bottomed cylindrical body protruding upward in the height direction from the side of the upper surface 10a. At the center of the bottom surface of the outer conductor connection portion 11, a recessed portion 11a which is recessed downward in the height direction is formed (see FIGS. 1 and 4). The seal part 11b is formed in the recessed part 11a (refer FIG. 4). The seal portion 11 b is formed by being filled with a waterproof potting agent as a “waterproof material”. Such potting material can be composed of a hydrophobic gel or a rubber-like elastic body. By providing the seal portion 11 b so as to fill the recess 11 a of the outer conductor connection portion 11, it is possible to prevent moisture from entering through the boundary between the terminal 2 disposed in the outer conductor connection portion 11 and the housing 1.

  The partition wall 12 is provided between the recess 10 c of the main body 10 and the recess 11 a of the outer conductor connection portion 11 so as to close the side of the imaging component case when the camera module is assembled (FIG. 1, 2 and 4). The partition wall 12 is integrally formed with the above-described protrusion 10 d.

  In the main body portion 10, a through hole 10f connecting the bottom surface 10e of the recess 10c and the lower surface 10b of the protrusion 10d is formed (see FIG. 4). The through hole 10 f is configured such that one end opens toward the inner contact portion 20 and the other end opens toward the “held portion”. The other end of the through hole 10 f communicates with the recess 10 c. The through holes 10 f are formed corresponding to the positions of the through holes 26 a, 26 b and 26 c of the terminals 2 A to 2 F described later. That is, those through holes 10f are used to hold the arrangement of the terminals 2A to 2F at the time of molding of the housing 1 through a forming jig 63 to a forming jig 65 (see FIG. 8) described later. It is a part formed by being inserted into and molded into.

  Seals 13 are formed on the inside of the recess 10 c and the inside of each through hole 10 f. The seal portion 13 is formed by being filled with a waterproof potting agent similar to the seal portion 11 b provided in the outer conductor connection portion 11. Specifically, as shown in FIG. 4, the seal portion 13 has a recess filling portion 13 a and a hole filling portion 13 b. In addition, in FIG. 1, the top view before forming the seal part 13 is shown so that the wide parts 27A, 27B, 27C arranged in the recessed part 10c can be seen. By filling such a seal portion 13 inside the recess 10c and inside the through holes 10f, it is possible to prevent moisture from infiltrating from the boundary between the housing 1 and the terminals 2A to 2F.

Terminal 2A to terminal 2F

  The plurality of terminals 2 are electrical conductors made of conductive metal pieces, and are held by the housing 1. Each terminal 2 includes an inner contact portion 20 as a "first contact portion" disposed in the main body portion 10, an outer contact portion 21 as a "second contact portion" disposed in the outer conductor connection portion 11, and an inner side A relay portion 22 is provided which connects the contact portion 20 and the outer contact portion 21 and is disposed on the partition wall 12. Each of the terminals 2 is formed as a single part by bending a flat conductive metal piece as a material into an elongated plate and then bending it.

  In the present embodiment, the plurality of terminals 2 are configured by six terminals 2A to 2F as shown in FIG. 3. The six terminals 2A to 2F have many common configurations. Therefore, in the present specification, the six terminals 2A to 2F may be collectively described as the terminal 2 for convenience. When the configuration relating to the terminal 2 is individually described, capital letters "A" to "F" are added and described. The configuration of the six terminals 2A to 2F here is an example, and may be five or less or seven or more.

  In the present embodiment, the terminals 2 can be divided into two groups depending on the shape. That is, the terminals 2A to 2C as "first terminals" form one group, and the terminals 2D to 2F as "second terminals" form another group. The group of the terminals 2A to 2C and the group of the terminals 2D to 2F are arranged so as to overlap in front view. The terminal 2A and the terminal 2C have the same sectional shape as the terminal 2B shown in FIG. 4, and the terminal 2D and the terminal 2F have the same sectional shape as the terminal 2E shown in FIG.

  Furthermore, the group of terminals 2A to 2C is arranged to be shifted to the side closer to the inner contact portion 20 in the X direction (right side in FIGS. 1 and 4) and to the upper side in the Z direction with respect to the group of terminals 2D to 2F. ing. The terminal 2A, the terminal 2B, and the terminal 2C are arranged to overlap with the terminal 2D, the terminal 2E, and the terminal 2F on the near side (upper side in the Z direction) in plan view.

As shown in FIG. 3, the outer contact portion 21 is connected to the relay portion 22 via the contact portion side base 24 and the relay portion side base 25. The outer contact portion 21 extends in the shape of a prism from the upper end of the contact portion side base 24 to the upper side in the Z direction. The contact portion side base 24 is formed in a flat plate shape whose plate thickness is in the X direction and the plate surface extends in the direction of the YZ plane. Then, in the contact portion side base 24 in a state in which the housing 1 is an integral molded body including the terminal 2, the substantially lower half is embedded in the recess 11a, and the substantially upper half is exposed to the inner space of the outer conductor connection portion 11. doing.

  The group of the outer contact portions 21A to 21C is predetermined on the side (right side in FIGS. 1 and 4) closer to the inner contact portion 20 in the X direction with respect to the group of the outer contact portions 21D to 21F. Are offset by the specified distance. This distance corresponds to the distance between the contacts of the plurality of terminals provided in the harness component.

  One end of the relay portion 22 is connected to the contact portion side base 24, and the other end is connected to the inner contact portion 20. And relay part 22 is mainly constituted by three parts, and it is formed in a reverse Z shape longer in the X direction to the Z direction in a front view (see FIG. 4 etc.). The relay portion 22 is disposed in the X direction so as to extend in the Z direction at portions on one end side and the other end side, and is extended in the X direction at the intermediate portion so as to extend the plate thickness Z It is arranged in the direction.

  The relay section 22 is mostly embedded in the partition wall 12, and on the other end side where the group of the relay section 22A to the relay section 22C is connected to the inner contact section 20, the group of the relay section 22D to the relay section 22F is The one end side connected to the contact portion side base 24 is exposed to the outside of the housing 1 respectively. However, the relay portion 22 may be configured to be entirely embedded in the partition wall 12.

  The inner contact portion 20A to the inner contact portion 20C extend from the other end of the relay portion 22 to a side (left side in FIGS. 1 and 4) approaching the outer contact portion 21 in the X direction. That is, the terminals 2A to 2C each have a bending portion connecting the inner contact portion 20A to the inner contact portion 20C and the relay portion 22A to the relay portion 22C (see FIG. 3, FIG. 4, FIG. 8, etc.) . On the other hand, the inner contact portion 20D to the inner contact portion 20F are bent from the other end of the relay portion 22 and extend to the side (right side in FIGS. 1 and 4) away from the outer contact portion 21 in the X direction. And relay part 22A-relay part 22C has extended the upper part in the Z direction of inner side contact parts 20A-20C and inner side contact parts 20D-20F. The directions in which the inner contact portions 20A to 20C and the inner contact portions 20D to 20F extend from the other end of the relay portion 22 may be any other combination as long as they are exposed outside the housing 1.

  The relay unit side base 25 is adjacent to the lower side in the Z direction of the contact unit side base 24. The relay unit side base 25 is formed in a prismatic shape extending in the Y direction. The relay portion side base 25 is formed flush with the contact portion side base 24 in the YZ plane, and protrudes outward from the contact portion side base 24 in the Y direction.

  The relay portion side base 25 has a function of changing the distance between the terminals 2 adjacent in the Y direction in the inner contact portion 20 and the outer contact portion 21. That is, with regard to the terminals 2A and 2D, the relay portions 22 (22A and 22D) are disposed on the front side in the Y direction with respect to the relay portion side base 25 (25A and 25D), and on the back side in the Y direction. The contact part side base 24 (24A, 24D) is arrange | positioned. On the other hand, with regard to the terminals 2C and 2F, the relay portions 22 (22C, 22F) are disposed further to the rear side in the Y direction with respect to the relay portion side base 25 (25C, 25F). The contact part side base 24 (24C, 24F) is arrange | positioned. Thereby, the outer contact portions 21 can be arranged at a wider interval than the inner contact portions 20. It is also possible to make the outer contact portions 21 narrower than the inner contact portions 20 by reverse arrangement.

  In the terminal 2B and the terminal 2E, the relay portion 22 (22B, 22E) and the contact portion side base 24 (24B, 24E) are coaxially arranged in the Y direction. Also about these, it may be shifted and arranged in the Y direction.

  In the camera module according to the present embodiment, the “held portion” in which the relay portion 22 is held by forming jigs 63 to 65 described later, and suppresses the change in the positional relationship between the inner contact portion 20 and the outer contact portion 21. It is characterized by having. According to the camera module of the present embodiment, the “holding portion” is held by the forming jigs 63 to 65 when the housing 1 is formed, whereby the inner contact portion 20 and the outer contact portion 21 of the terminal 2 are appropriately made. The housing 1 can be molded as an integral molded body including the terminal 2 while maintaining the positional relationship. Then, since the "held portion" is held by the forming jigs 63 to 65 and the terminal 2 does not shift in position, when the housing 1 and the terminal 2 are integrally molded, the terminal 2 moves carelessly. It can prevent that it is damaged.

  The “held portion” changes the positional relationship between the inner contact portion 20 and the outer contact portion 21 when the terminal 2 is attached to a cavity 61 (see FIG. 8) of the stationary mold 60 described later for molding the housing 1. For example, it may be configured to be able to be held by a jig such as molding jigs 63 to 65 so as to be suppressed. Therefore, the “held portion” may be configured, for example, as a knob that protrudes laterally from the relay portion 22. In this case, the knob portion is sandwiched by the forming jigs 63 to 65, the fixed side mold 60, and the movable side mold 62 described later, or is fitted to the forming jig 63 to 65 in which a cut is formed. The terminal 2 can be fixed at a predetermined position in the cavity 61 to prevent the displacement of the terminal 2.

  In the present embodiment, such a "held portion" is configured by the insertion holes 26 through which the forming jigs 63 to 65 are inserted, as shown in Figs. 1, 3 and 4. The insertion hole 26 is formed so as to penetrate in a direction intersecting the relay portion 22 extending in the X direction, that is, in the plate thickness direction of the relay portion 22. The penetration direction of the insertion hole 26 is not limited to the thickness direction of the relay portion 22. However, when the penetration direction of the insertion hole 26 is the thickness direction of the relay portion 22, metal processing (for example, punching) of the insertion hole 26 with respect to the relay portion 22 (terminal 2) is easy; There are many advantages such as that the structures such as 60 and molding jigs 63 to 65 can be simplified, and that the housing 1 can be easily molded because it can be matched with the direction of mold clamping. Therefore, the insertion hole 26 is preferably formed to penetrate in the plate thickness direction of the relay portion 22. Furthermore, when the insertion hole 26 is formed at the center of the relay portion 22 in the plate width direction (Y direction), processing of the insertion hole 26 with respect to the relay portion 22 (terminal 2) is easy.

  The insertion hole 26 is formed on the other end side of the relay portion 22 (the connection portion side with the inner contact portion 20). In the group of the terminals 2A to 2C, three of the insertion holes 26a as the "second insertion holes", the insertion holes 26b as the "first insertion holes", and the insertion holes 26c in order from the other end side of the relay portion 22 Two insertion holes 26 are formed at equal intervals along the X direction. For example, in the terminal 2A, an insertion hole 26Aa, an insertion hole 26Ab, and an insertion hole 26Ac are formed. On the other hand, in the group of the terminals 2D to 2F, a single insertion hole 26a is formed. For example, an insertion hole 26Da is formed in the terminal 2D.

  The insertion holes 26Aa to 26Ca are formed on the upper side in the Z direction of the inner contact portions 20A to 20C, respectively. The insertion holes 26Ab to 26Cb are formed on the upper side in the Z direction of the inner contact portions 20D to 20F, respectively. The insertion holes 26Ac to 26Cc are formed above the insertion holes 26Da to 26Fa in the Z direction. The insertion holes 26Ac to 26Cc are formed concentrically with the insertion holes 26Da to 26Fa in plan view. Therefore, when the forming jig 65 moves along the Z direction, it is inserted into the insertion holes 26Ac to 26Cc and the insertion holes 26Da to 26Fa, respectively.

  In the same manner as the inner contact portions 20A to 20C, the inner contact portions 20D to 20F extend from the other end of the relay portion 22 to the side approaching the outer contact portion 21 (left side in FIGS. 1 and 4) As a configuration to be configured, a region in which the insertion hole 26 is formed in the relay portion 22 of the inner contact portions 20D to 20F may be further ensured above the Z direction of the inner contact portions 20D to 20F. The insertion holes 26 may be formed concentrically with the insertion holes 26Ab to 26Cb in plan view. Thus, the housing 1 can be formed as an integral molded body including the terminals 2D to 2F while the inner contact portions 20 and the outer contact portions 21 are reliably maintained in an appropriate positional relationship with respect to the terminals 2D to 2F.

  If at least one insertion hole 26 is formed per one terminal 2, it can function as a "held portion". When a plurality of insertion holes 26 are formed in one terminal 2, the terminal 2 does not unintentionally rotate about any one of the forming jigs 63 to 65 as an axis, and Function as "is more enhanced. On the other hand, when the number of insertion holes 26 in one terminal 2 is too large, it is not preferable because the strength of the terminal 2 is reduced and the electrical conduction cross section is reduced. Therefore, the number of insertion holes 26 is preferably one to three per one terminal 2.

  According to the present embodiment, the “held portion” can be configured by the insertion hole 26 that can be easily formed. Since the insertion hole 26 only needs to form a hole in the relay portion 22, there is no need to separately form a portion such as a knob held by the forming jigs 63 to 65, and design and manufacture are easier. It is. Furthermore, according to the present embodiment, the positional relationship between the inner contact portion 20 and the outer contact portion 21 of the terminal 2 can be properly maintained by a simple method of inserting the forming jigs 63 to 65 into the insertion holes 26. it can. In addition, in the combination of the insertion hole 26 and the forming jigs 63 to 65, the movement of the terminal 2 in the XY direction other than the insertion and removal direction of the forming jigs 63 to 65 can be easily and surely stopped. Therefore, when the housing 1 and the terminal 2 are integrally molded, it is possible to prevent the terminal 2 from being inadvertently moved and damaged more reliably.

  The “held portion” can be configured to have the widening portion 27 protruding to the outside of the insertion hole 26. As shown in FIGS. 1 and 3, the widening section 27 is formed to widen the width of the plate surface in both directions in the Y direction from the relay section 22. When the terminal 2 is formed, the widening portion 27 can also be formed simultaneously with another portion, for example, by punching in press processing.

  Here, if the insertion hole 26 is formed, stress concentration is likely to occur around it, and the plate width of the material of the terminal 2 is shortened in the vicinity thereof including the insertion hole 26 to lower the structural strength. However, according to the present embodiment, since the "held portion" has the widened portion 27 outside the insertion hole 26, stress concentration easily occurs, and the region outside the insertion hole 26 whose structural strength is reduced is reinforced. can do. Therefore, the strength reduction of the terminal 2 resulting from the formation of the insertion hole 26 can be offset. Furthermore, when the insertion hole 26 is formed, the conduction cross-sectional area of the region including the insertion hole 26 is reduced, so the allowable current value associated with the cross-sectional area is also reduced. However, according to the present embodiment, since the "held portion" has the widened portion 27 outside the insertion hole 26, the conduction cross-sectional area can be secured, and the allowable current value can be set high. From the above, according to the present embodiment, the application range of the electronic component can be expanded.

  By securing the large width of the plate surface of the relay portion 22 by the widening portion 27, it is also possible to form the diameter of the insertion hole 26 larger than the width of the plate surface of the relay portion 22 at locations other than the widening portion 27. As a result, the tips of the forming jigs 63 to 65 can be tapered to facilitate the insertion of the forming jigs 63 to 65 into the insertion hole 26.

  As shown in FIG. 1 and FIG. 3, the widening portion 27 has a rectangular shape in which both side surfaces are linear in a plan view. The widening portion 27 is easy to form because it has such a simple configuration. However, the wide portion 27 is not limited to the rectangular shape, and may be formed in a wave shape along the outer diameter of the insertion hole 26, for example. By forming both side surfaces of the widening portion 27 in a wave-like manner, it is possible to use a constricted portion in which the width of the plate surface is narrowed for transporting the terminal 2, and furthermore, compared to the configuration where both side surfaces are linear. You can reduce the amount of

  In the case where the "held portion" is formed in a shape like a knob, the knob may also function as the widened portion 27. By doing this, for example, when the transfer hole of the terminal 2 is provided in the relay portion 22, it is possible to eliminate the inconvenience when the above-mentioned insertion hole 26 is formed.

  The inner contact portion 20 is formed in a substantially square flat plate shape whose plate thickness is in the Z direction and the plate surface extends in the direction of the XY plane. The inner contact portion 20 is configured to be conductively connected to the unshown contacts of the imaging component housed in the imaging component case on the lower surface in the Z direction.

  A receiving portion 28 is formed on the upper surface of the inner contact portion 20 in the Z direction. The receptacles 28A to 28C as "second receptacles" of the group of the terminals 2A to 2C face the insertion holes 26Aa to 26Ca of the terminals 2A to 2C, respectively. That is, the group of the terminals 2A to 2C is configured to have the insertion holes 26Aa to 26Ca and the receiving portions 28A to 28C in single conductive metal pieces, respectively. The receiving portions 28A to 28C are positioned on the extension of the insertion and removal direction of the forming jig 63 through which the insertion holes 26Aa to 26Ca are respectively inserted (see FIG. 8 and the like). Receiving portions 28D to 28F as “first receiving portions” of the group of terminals 2D to 2F face the insertion holes 26Ab to 26Cb of the terminals 2A to 2C, respectively.

  The receiving portion 28 has a function of receiving the forming jigs 63 and 64 inserted into the insertion hole 26. Then, the terminal 2 having received the forming jigs 63 and 64 by the receiving portion 28 has a predetermined position in the fixed side mold 60 by pressing the inner contact portion 20 against the cavity 61 of the fixed side mold 60. Act to be fixed to Thus, with the combination of the receiving portion 28 and the forming jigs 63 and 64 arranged concentrically in a plan view with the insertion hole 26, the movement of the terminal 2 in the Z direction can be stopped easily and reliably. Therefore, in the terminal 2 of the present embodiment, the terminal 2 is maintained in an appropriate positional relationship between the inner contact portion 20 and the outer contact portion 21 in all directions of XYZ by the configuration having the insertion hole 26 and the receiving portion 28. The housing 1 can be molded as an integral molded body including.

Method of manufacturing electronic component [FIG. 8]

  Next, an embodiment of a method of manufacturing an electronic component will be described with reference to the drawings. Here, a housing 1 having a main body portion 10, an outer conductor connection portion 11, a partition 12 separating the main body portion 10 and the outer conductor connection portion 11, an inner contact portion 20 disposed on the main body portion 10, an outer conductor For a camera module which is an “electronic component” including a terminal 2 having an outer contact portion 21 disposed in the connection portion 11 and a relay portion 22 connecting the inner contact portion 20 and the outer contact portion 21 to the partition wall 12 A method of manufacturing the housing 1 will be described.

  First, the terminal 2 for electrically connecting between the imaging component and the external device is prepared. The terminal 2 is formed as a single component by bending and processing a flat conductive metal piece as a material into an elongated plate shape. When the conductive metal piece is stamped out, the insertion hole 26 and the widening portion 27 can be simultaneously formed. However, the insertion holes 26 may be separately formed in a later step.

  Next, integral molding of the housing 1 and the terminal 2 is performed. The housing 1 is formed of an insulating hard resin, and the finished product is an integral molded body including the terminal 2 of the metal part.

  The terminal 2 on which the inner contact portion 20, the outer contact portion 21, the relay portion 22 and the like are formed is installed in the cavity 61 of the stationary mold 60 for molding the housing 1, as shown in FIG. 8A. The cavity 61 is formed to correspond to the shape of the inner contact portion 20.

  The insertion hole 26 is formed in the terminal 2 installed in the cavity 61 (refer FIG. 8 (B)). On the other hand, in the movable side mold 62 used in combination with the fixed side mold 60, there are a forming jig 63, a forming jig 64 and a forming jig 65 which protrude toward the fixed side mold 60 side. It is provided corresponding to the position of the insertion hole 26 (refer FIG. 8 (B)). The forming jig 65 is formed to have a lower projecting height than the other forming jigs 63 and the forming jig 64. These molding jigs 63 to 65 project from a pressing portion 66 which extends in a direction intersecting with the moving direction of the movable side mold 62.

  When the movable-side mold 62 is closed with respect to the fixed-side mold 60, the molding jig 63 passes through the insertion hole 26Ba and contacts the receiving portion 28B, and the molding jig 64 passes through the insertion hole 26Bb. As a result, contact is made with the receiving portion 28E. At that time, the forming jig 65 passes through the insertion hole 26Bc and reaches near the lower end of the insertion hole 26Ea. Then, the pressing portion 66 contacts the upper surface of the relay portion 22 of the group of the terminals 2A to 2C.

  The forming jig 63 holds the relay portion 22 of the group of the terminals 2A to 2C and fixes the inner contact portion 20. The forming jig 64 holds the relay portion 22 of the group of the terminals 2A to 2C and fixes the inner contact portion 20 of the terminals 2D to 2F. The forming jig 65 holds the relay portion 22 of the group of the terminals 2A to 2C and holds the relay portion 22 of the terminals 2D to 2F. Further, the pressing portion 66 holds the relay portion 22 of the group of the terminals 2A to 2C from the upper side. The “held portion” provided in the relay portion 22 is fixed to a predetermined position of the cavity 61 by the forming jigs 63 to 65 and the pressing portion 66 (see FIG. 8C).

  In this state, the resin material is injected into the cavity 61 to mold the housing 1 as an integral molded body including the terminal 2.

  After the forming jigs 63 to 65 are removed, through holes 10f communicating with the through holes 26a, 26b and 26c are formed. Furthermore, the recess 10c communicates with the through hole 10f. By filling the recess 10c and the through hole 10f with a waterproof potting agent, the recess filling portion 13a and the hole filling portion 13b, that is, the seal portion 13 are formed.

  In the present embodiment, the projecting heights of the forming jig 63 and the forming jig 64 from the pressing portion 66 are the groups of the terminals 2A to 2C and the terminals from the upper end of the insertion hole 26 in the group of the terminals 2A to 2C. It is formed equal to the length to the receiving part 28 of the group of 2D-2F. However, the protruding heights of the forming jig 63 and the forming jig 64 may be longer than this. In this case, the resin is also filled on the upper side of the insertion hole 26 in the group of the terminals 2A to 2C, and the forming jig 63 and the forming jig do not expose the relay portion 22 of the group of the terminals 2A to 2C. Only holes after 64 have been removed will be exposed.

  According to the present embodiment, since the insertion hole 26 as the “held portion” provided in the relay portion 22 of the terminal 2 is fixed at a predetermined position of the cavity 61 by the forming jigs 63 to 65, The housing 1 and the terminal 2 can be integrally molded while maintaining the inner contact portion 20 and the outer contact portion 21 in an appropriate positional relationship. In particular, the positional relationship between the inner contact portion 20 and the outer contact portion 21 that is likely to change when the terminal 2 has the relay portion 22 and the like in mounting in the mold, The insertion holes 26 as “are properly maintained by being held by the forming jigs 63 to 65.

  Specifically, since the plurality of insertion holes 26 arranged apart from each other along the length direction of the relay portion 22 are held by the forming jigs 63 to 65, the relay holes 22 extend outward with respect to the length center of the relay portion 22. It is possible to effectively prevent misalignment due to the rotation of the Further, since the terminals 2A and 2D, the terminals 2B and 2E, and the terminals 2C and 2F are held by the common forming jigs 63 to 65, respectively, the terminals 2A to 2C and the terminals 2D to 2F arranged vertically in the Z direction. Positional displacement in the XY direction can be reliably prevented. For this reason, after the terminal 2 is fixed to the cavity 61, the movable side mold 62 is closed to the fixed side mold 60 or the resin material is injected to integrally form the housing 1 and the terminal 2. The terminal 2 can be prevented from moving inadvertently and being damaged.

Modification of Embodiment [FIGS. 5 to 7]

  Next, a modification of the present embodiment will be described with reference to the drawings. The housing 4 of the modified example is different in the configuration corresponding to the inner contact portion 20 of the housing 1 of the embodiment described above and the insertion hole 26 of the relay portion 22, but the configuration of the other portions and the function and effect are the same. Here, a configuration different from the above-described embodiment will be mainly described.

Housing 4

  The housing 4 is formed of an insulating hard resin, and is an integral molded body including a plurality of terminals 5 for conductive connection between the imaging component and the external device. The shape itself of the housing 4 is substantially the same as the housing 1.

Terminal 5A to terminal 5F

  The terminal 5 is an electrical conductor made of a conductive metal piece. The terminal 5 includes an inner contact portion 50 as a "first contact portion" disposed in the main body portion 10, an outer contact portion 21 as a "second contact portion" disposed in the outer conductor connection portion 11, and an inner contact A relay portion 52 is provided which connects the portion 50 and the outer contact portion 21 and is disposed on the partition wall 12. The plurality of terminals 5 are configured by six terminals 5A to 5F as shown in FIG.

  The inner contact portion 50 is connected to the relay portion 52 via the inner contact portion side base 53, as shown in FIG. The inner contact portion side base 53 is formed in a flat plate shape whose plate thickness is in the X direction and the plate surface extends in the direction of the YZ plane. Then, in the state in which the housing 4 is an integral molded body including the terminal 5, most of the upper portion is embedded in the protrusion 10d, and a portion of the lower portion is below the protrusion 10d. Projected into

  As shown in FIG. 5, the inner contact portion side base portion 53 protrudes in both directions in the Y direction more than the inner contact portion 50 and the relay portion 52, and the plate surface is formed wider. When the terminal 5 is formed, the inner contact portion side base 53 can also be formed simultaneously with other portions, for example, by punching in press processing. When the terminal 5 is attached to the cavity of the molding die, the inner contact portion side base 53 wider than the inner contact portion 50 strikes the cavity and acts to prevent the displacement of the terminal 5 particularly in the Z direction. Do. On the other hand, when the terminal 5 attached to the cavity is clamped, the inner contact portion side base 53 wider than the relay portion 52 is provided by a jig formed on the movable side mold 62 as shown in FIG. In particular, it acts to prevent the displacement of the terminal 5 in the Z direction.

  Therefore, the terminal 5 can maintain the positional relationship of the inner contact part 50 and the outer contact part 21 appropriately at the time of shaping | molding by having the inner contact part side base 53. As shown in FIG.

  In addition, since the group of relay part 52A-relay part 52C is located above the group of relay part 52D-relay part 52F in the Z direction, the group of inner contact part side base 53A-inner contact part side base 53C Is longer in the Z direction than in the inner contact portion side base 53D to the inner contact portion side base 53F.

  The inner contact portion 50 extends in a prismatic shape downward from the lower end of the inner contact portion side base 53 in the Z direction. The group of the inner contact parts 50A to the inner contact parts 50C is the side farther to the outer contact parts 21 in the X direction with respect to the group of the inner contact parts 50D to the inner contact parts 50F (in FIGS. The right side is arranged to be offset by a predetermined distance. This distance is adapted, for example, to the spacing of the contacts of the movable connector as the contacts of the imaging component.

  Also in the camera module of the modified example of the present embodiment, the relay portion 52 is held by a molding jig and inserted as a "held portion" which suppresses a change in the positional relationship between the inner contact portion 50 and the outer contact portion 21. It has a hole 56.

  The insertion hole 56 is formed on the other end side of the relay portion 52 (the connecting portion side with the inner contact portion 50). In the modification of the present embodiment, both of the group of the terminals 5A to 5C as the "first terminal" and the group of the terminals 5D to 5F as the "second terminal" The two insertion holes 56 of the insertion hole 56a and the insertion hole 56b are formed along the X direction in order from the side of. For example, an insertion hole 56Aa and an insertion hole 56Ab are formed in the terminal 5A. Furthermore, for example, an insertion hole 56Da and an insertion hole 56Db are formed in the terminal 5D.

  The insertion holes 56Aa to 56Ca are formed concentrically with the insertion holes 56Da to 56Fa in plan view, and the insertion holes 56Ab to 56Cb are respectively planed with the insertion holes 56Db to 56Fb. It is formed in the concentric position. Therefore, when the forming jig is moved along the Z direction, the insertion holes 56Aa to 56Ca and the insertion holes 56Da to 56Fa and the insertion holes 56Ab to 56Cb and the insertion holes 56Db to 56Fb are respectively inserted. ing. Such insertion holes 56Aa to 56Ca, insertion holes 56Da to 56Fa, insertion holes 56Ab to 56Cb, and insertion holes 56Db to 56Fb particularly function to prevent positional deviation of the terminal 5 in the XY direction.

  Furthermore, the insertion holes 56Da-Fa as the "third insertion hole" and the insertion holes 56Db-Fb as the "third insertion hole" are respectively the insertion holes 56Aa-Ca as the "first insertion hole" and the The opening area is smaller than the insertion holes 56Ab-Cb as the first insertion holes "(see FIG. 7). In accordance with this, the tip end of the forming jig to be inserted into the insertion holes 56Da to Fa and the insertion holes 56Db to Fb is thinner than the base end. Therefore, in the group of terminals 5D to 5F, a stepped portion is formed at the boundary between the base end side and the front end side of the molding jig at the time of mold clamping, and the stepped portion is relay portion 52D to 52F ("first receiving portion By abutting on the receiving portions 58D to 58F as the “portions”, the relay portions 52D to 52F operate so as not to float upward in the Z direction. Such insertion holes 56Aa to 56Ca, insertion holes 56Da to 56Fa, insertion holes 56Ab to 56Cb, and insertion holes 56Db to 56Fb particularly function to prevent positional deviation of the terminal 5 in the Z direction.

  In addition, insertion holes 56Da-Fa and insertion holes 56Db-Fb are circular if they are formed with a small opening area without protruding from the outer edges of insertion holes 56Aa-Ca and insertion holes 56Ab-Cb in plan view, respectively. It does not have to be.

  As described above, in the insertion hole 56, the terminal 5 is fixed at a predetermined position in the cavity by inserting the molding jig, and the positional deviation of the terminal 5 can be prevented in all directions of XYZ.

  As described above, also in the modification of the present embodiment, the relay portion 52 of the terminal 5 is provided with the insertion hole 56 as a "held portion" which can be held by the forming jig. Therefore, by holding the "held portion" by the forming jig at the time of forming the housing 4, the terminal 5 can be maintained while maintaining the inner contact portion 50 and the outer contact portion 21 of the terminal 5 in an appropriate positional relationship. The housing 4 can be molded as an integral molded body including. And since the "held part" is held by the forming jig and the terminal 5 does not shift, when the housing 4 and the terminal 5 are integrally molded, the terminal 5 is moved carelessly and damaged.
