  However, in the case of Patent Document 1, in the electronic device 200, the circuit board 220 is rigidly fixed to the housing 210 by the locking claws. Therefore, there is a possibility that a slight deviation may occur between the central axis of the first component arranged at the one end 212 and the central axis of the second component on the circuit board 220 due to an assembly error or the like.

Since there is no portion and the arc portion pattern is easily deformed, it is possible to prevent local extreme bending deformation from occurring.

  Therefore, even when the relay terminal repeatedly undergoes elastic deformation, it is difficult for fatigue to remain in the conductive pattern layer, and the reliability and durability of the connection between the terminal fitting in the connector housing and the contact part of the second component can be improved. it can.

  The leading end 321 a of the internal conductor 321 is a portion that is conductively connected to the contact portion on the circuit board 422. As shown in FIG. 3, the inner conductor 321 is fixed to the terminal holding portion 312 by silicon potting 324. The inner conductor 321 is fixed to the terminal holding portion 312 so that the tip end portion 321 a protrudes from the surface of the flange portion 311. Further, since the silicon potting 324 is applied, the terminal holding portion 312 is waterproofed.

  As shown in FIG. 4, in the electronic device connector 30 according to this embodiment, when the connector housing 31 is coupled to the other end 411 of the housing 41, the inner conductor 321 of the terminal fitting 32 and the distal end portion 322 a of the outer conductor 322. Is connected to the contact portion (not shown) of the second component 45 on the circuit board 42 through the relay terminal 33.

  The relay terminal 33 is sandwiched between the tip of the terminal fitting 32 and the contact portion of the second component 45 when the connector housing 31 is coupled to the other end 411 of the housing 41. As shown in FIG. 5, the relay terminal 33 includes an insulating elastic material layer 331 and a conductive pattern layer (conductive portion) 332 formed on the surface of the insulating elastic material layer 331. .

  The insulating elastic material layer 331 is formed by molding a foamed sponge made of an insulating resin into a predetermined shape. By sandwiching the tip of the terminal fitting 32 and the contact portion of the second component 45, the arrow X1 in FIGS. The circuit board 42 is urged toward the one end 415 side of the housing 41 by elastically deforming in the direction.

  As shown in FIG. 5, the insulating elastic material layer 331 of the present embodiment has at least one side surface smoothly smoothing the surface 331 a on the contact portion side and the surface 331 b on the terminal fitting 32 side of the insulating elastic material layer 331. It is formed on the connecting convex arc surface 331c.

  The conductive pattern layer 332 is a conductor layer that is laminated on the surface of the insulating elastic material layer 331 and electrically connects the contact portion on the second component 45 and the terminal fitting 32.

  The conductive pattern layer 332 of the present embodiment is formed on the contact contact pattern 332a formed on the contact portion side surface 331a of the insulating elastic material layer 331 and the surface 331b of the insulating elastic material layer 331 on the terminal fitting 32 side. A terminal contact pattern 332b that is stacked and a circular arc pattern 332c that is stacked on the surface of the convex arc surface 331c and connects the contact contact pattern 332a and the terminal contact pattern 332b are provided.

  A large number of conductive pattern layers 332 are formed at a predetermined pitch, and the leading end portion 321a of the internal conductor 321 and the leading end portion 322a of the external conductor 322 and each contact portion of the circuit board 422 are a plurality of conductive pattern layers 332. Electrically connected. As a result, the leading end portion 321a of the internal conductor 321 and the leading end portion 322a of the external conductor 322 are perpendicular to the central axis O1 with respect to each contact portion of the circuit board 422 (the vertical direction in FIG. 3 and the direction perpendicular to the paper surface). ), The leading end portion 321a of the inner conductor 321 and the leading end portion 322a of the outer conductor 322 and each contact portion of the circuit board 422 are reliably electrically connected by any one of the conductive pattern layers 332. The Accordingly, the alignment of the distal end portion 321a of the inner conductor 321 and the distal end portion 322a of the outer conductor 322 and each contact portion of the circuit board 422, in other words, the alignment of the electronic device connector 30 and the electronic device 40 is high. It does not require accuracy and is easy to assemble.

  As the relay terminal 33 of this embodiment, for example, a GB-U type connector manufactured by Shin-Etsu Polymer Co., Ltd. can be used.

  In the case of the present embodiment, the relay terminal 33 is previously fixed at a predetermined position on the circuit board 422 with an adhesive. Therefore, when the connector housing 31 is coupled to the other end 411 of the housing 41, the relay terminal 33 is not moved inadvertently, and the coupling work between the electronic device connector 30 and the electronic device 40 can be facilitated. it can.

  According to the configuration of the electronic device connector 30 of the embodiment described above, when the connector housing 31 is coupled to the other end 411 of the housing 41 of the electronic device 40, the relay terminal 33 is connected to the terminal of the electronic device connector 30. The terminal fitting 32 and the electronic device 40 in the electronic device connector 30 are sandwiched between the fitting 32 and the contact portion on the circuit board 42 in the electronic device 40 and the conductive pattern layer 332 on the surface of the relay terminal 33. The contact portion on the inner circuit board 42 is conductively connected.

  Then, the relay terminal 33 sandwiched between the terminal fitting 32 of the electronic device connector 30 and the contact portion on the circuit board 42 in the electronic device 40 has the insulating elastic material layer 331 elastically deformed into a compressed state. A biasing force that presses the circuit board 42 toward the one end 415 side of the housing 41 is generated by the restoring force due to the deformation. Therefore, the circuit board 42 is pressed against the substrate reference surface 417 of the housing 41, and the central axis of the second component 45 mounted on the circuit substrate 42 is aligned with the housing 41 due to the positioning performance by the substrate reference surface 417. Is positioned coaxially with the central axis of the first component 44 mounted at one end 415 of the first part 44.

  Accordingly, the first component 44 and the second component 45 of the electronic device 40 are aligned coaxially by simply performing a simple operation of coupling the connector housing 31 to the other end 411 of the casing 41 of the electronic device 40. Can be easily obtained.

  In addition, according to the configuration of the electronic device connector 30 of the embodiment, the terminal fitting 32 of the electronic device connector 30 and the electronic device are connected in a state where the connector housing 31 is coupled to the other end 411 of the housing 41 of the electronic device 40. The insulating elastic material layer 331 of the relay terminal 33 sandwiched between the contact portions on the circuit board 42 in the 40 is elastically deformed, thereby absorbing a dimensional error due to an assembly error or the like. Therefore, a stable conductive connection state can be obtained between the terminal fitting 32 in the electronic device connector 30 and the contact part of the second component 45 on the circuit board 42.

  In addition, according to the configuration of the electronic device connector 30 according to the embodiment, the relay terminal 33 includes the insulating elastic material layer 331 and the conductive pattern layer 332 laminated on the surface of the insulating elastic material layer 331. Since the structure is simple and the manufacturing is easy, the cost can be reduced.

  In addition, according to the configuration of the electronic device connector 30 of the embodiment, the insulating elastic material layer 331 of the relay terminal 33 has at least one side surface on the contact portion side surface of the insulating elastic material layer 331 and the terminal fitting 32. It is formed on a convex arc surface 331c that smoothly connects the side surface. The conductive pattern layer 332 formed on the surface of the insulating elastic material layer 331 includes the contact contact pattern 332a formed on the surface of the insulating elastic material layer 331 on the contact portion side, and the insulating elastic material layer. A terminal contact pattern 332b formed on the surface of the terminal fitting 32 side of 331 and an arc portion pattern 332c formed on the surface of the convex arc surface 331c and connecting the contact contact pattern 332a and the terminal contact pattern 332b. Has been.

  Therefore, when the thickness of the insulating elastic material layer 331 changes when the relay terminal 33 is sandwiched between the tip of the terminal fitting 32 and the contact portion of the second component 45, stress concentration occurs in the conductive pattern layer 332. Since there is no easy sharp bent portion and the arc portion pattern 332c is easily deformed, it is possible to prevent local extreme bending deformation from occurring.

  Therefore, even when the relay terminal 33 repeats elastic deformation, fatigue hardly remains in the conductive pattern layer 332, and reliability and durability of connection between the terminal fitting 32 in the connector housing 31 and the contact portion of the second component 45. Can be improved.

6 and 7 show an electronic device connector 30A as a comparative example.
The electronic device connector 30A is a connector that is coupled to the other end 411 of the housing 41 of the electronic device 40A that is the in-vehicle camera shown in the embodiment, but instead of the relay terminal 33, the spring terminal fitting 51, 52 is used. Further, in the electronic device 40A, the circuit board 42 on which the second component 45 is mounted is fixed to the housing 41 by engagement with a locking claw provided inside the housing 41.

  In addition, in the connector 30A for electronic devices and the electronic device 40A, about the structure which is common in the connector 30 for electronic devices and the electronic device 40 of one Embodiment, description is abbreviate | omitted by attaching | subjecting a code | symbol common to one Embodiment.

  The spring terminal fittings 51 and 52 are plate springs formed by bending a metal plate into a square shape, and are fixedly mounted by soldering 60 to the tips of the inner conductor 321 and the outer conductor 322 of the terminal fitting 32 shown in the above embodiment. The

  When the flange portion 311 of the connector housing 31A of the electronic device connector 30A is coupled to the other end 411 of the housing 41 of the electronic device 40, the spring terminal fittings 51 and 52 are elastically deformed at the distal ends of the spring terminal fittings 51 and 52. In this state, the inner conductor 321 and the outer conductor 322 in the electronic device connector 30 </ b> A are electrically connected to the contact portion on the circuit board 422 by contacting the contact portion of the circuit board 422 (see FIG. 3) in the electronic device 40. Is done.

  In the case of this comparative example, the circuit board 42 in the electronic device 40 is fixed to the housing 41 by a locking claw, and the circuit board 42 is rattled due to dimensional tolerance or assembly error. It may be difficult to position the central axis and the central axis of the first component 44 coaxially.

  Further, in the configuration of this comparative example, the mounting accuracy of the spring terminal fittings 51 and 52 is likely to vary due to the soldering variation of the spring terminal fittings 51 and 52. Further, it takes time for soldering work, and it becomes difficult to improve the productivity of the electronic device connector 30A.

  On the other hand, in the electronic device connector 30 according to the embodiment described above, it is possible to prevent the occurrence of problems that occur in the electronic device connector 30A.

In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, the relay terminal may have a configuration in which a conductive pattern layer is formed on the surface of an insulating elastic material layer having a circular or oval cylindrical shape or a rectangular column shape having a rectangular cross section. In addition, the relay terminal may have a configuration in which a conductor is embedded through a column having a circular, elliptical, or rectangular cross section from one end surface to the other end surface.

  Although the structure of the relay terminal can be modified in this way, it is most preferable to stack the conductive pattern layer on a curved surface as in the above embodiment, and the conductive pattern layer can be easily bent and deformed without fear of damage. it can.

  In the above embodiment, the second component is the image sensor provided on the circuit board, but the image sensor as the second component may not be provided on the circuit board. The image sensor may be provided in the housing without being mounted on the circuit board.

  In addition, the electronic device in which the electronic device connector of the present invention is used is not limited to the in-vehicle camera shown in the embodiment. In the electronic device connector of the present embodiment, the central axis of the second component on the circuit board provided on the other end side of the casing is coaxial with the central axis of the first component on the one end side of the casing.
