The housing portion 32 of the connector 30 closes the mounting opening 16 of the housing 12. Further, the terminal portion 40 of the connector 30 is held by the housing portion 32.

Here, as shown in FIGS. 4A and 4B, the terminal portion 40 includes a first terminal portion 42 and a second terminal portion 44 formed separately from the first terminal portion 42. .. An external device 100 is connected to the external connection terminal portion 42A of the first terminal portion 42 shown in FIG. 6, and the first relay connection portion 42B of the first terminal portion 42 is connected to the external connection terminal portion 42A. On the other hand, the internal connection terminal 44A of the second terminal 44 is connected to the internal conductor 22 (see FIG. 1), and the second relay connection 44C of the second terminal 44 is connected to the internal connection terminal 44A. It is connected by being connected and attached to the first relay connection portion 42B. Therefore, for example, when the shape, arrangement position, etc. of the internal conductor 22 (see FIG. 1) are changed due to a specification change or the like, the second terminal portion (44) having a shape corresponding to the shape is attached to the first terminal portion 42. Therefore, it is possible to deal with the situation without changing the shape of the first terminal portion 42 (that is, to enable conductive connection between the connector 30 and the internal conductor 22).

Further, in the present embodiment, the housing portion 32 shown in FIG. 2 is mounted in the mounting opening 16 of the housing 12, so that the internal connection terminal portion 44A is connected to the internal conductor 22 as shown in FIG. Is set to. Therefore, for example, it is not necessary to attach the connector to the mounting opening and then solder one end of the lead wire inside the device to the terminal portion of the connector, so that the assembling workability is good. That is, the connector 30 and the internal conductor 22 can be easily conductively connected.

Further, in the present embodiment, as shown in FIGS. 4A and 4B, the housing portion 32 has a first housing portion 34 and a second housing portion 36. Then, the second housing portion 36 is assembled to the first housing portion 34 (see FIG. 7B). Here, the first housing portion 34 holds the first terminal portion 42, and the connector first component 30A is formed by the first housing portion 34 and the first terminal portion 42. Further, the second housing portion 36 holds the second terminal portion 44, and the connector second component 30B is formed by the second housing portion 36 and the second terminal portion 44. Therefore, for example, when the shape, arrangement position, etc. of the internal conductor 22 (see FIG. 1) are changed due to a specification change or the like, a second connector component (30B) provided with a second terminal portion (44) having a shape corresponding to the change. ) Is attached to the existing connector first component 30A.

Further, in the present embodiment, the relative movement suppressing mechanism 38 (that is, the convex portion 34X of the first housing portion 34 and the concave portion 36Y of the second housing portion 36) shown in FIG. 7B is the connector mounting direction (see arrow X1). It suppresses the relative movement of the first housing portion 34 and the second housing portion 36 along the orthogonal directions. Therefore, the change in the relative positional relationship between the first housing portion 34 and the second housing portion 36 when viewed in the connector mounting direction (see arrow X1) is suppressed, and the first relay connection portion 42B and the second relay connection portion are suppressed. The disconnection of the connection portion with the 44C is effectively suppressed. Further, in the present embodiment, such an action and effect are realized by a simple configuration of uneven fitting.

Further, in the present embodiment, when the second housing portion 36 is assembled to the first housing portion 34 shown in FIG. 7A, the convex portion 34X of the first housing portion 34 and the concave portion 36Y of the second housing portion 36 are used to make the second housing portion 36. The housing portion 36 is guided in the direction in which the second relay connection portion 44C is directed toward the connection position with the first relay connection portion 42B. Therefore, the connection between the second relay connection unit 44C and the first relay connection unit 42B can be easily and surely performed.

Further, in the present embodiment, as shown in FIG. 6 and the like, the relay portion 44B of the second terminal portion 44 is the position and the inside of the second relay connection portion 44C when viewed in the connector mounting direction (see arrow X1). It is provided between the second relay connection portion 44C and the internal connection terminal portion 44A so as to be different from the position of the connection terminal portion 44A. Therefore, even if the first terminal portion 42, the second relay connection portion 44C, and the internal connection terminal portion 44A are extended along the connector mounting direction (see arrow X1), they are oriented in the connector mounting direction (see arrow X1). The position of the external connection terminal portion 42A and the position of the internal connection terminal portion 44A when viewed are shifted. Therefore, it can contribute to increasing the degree of freedom in the arrangement position of the inner conductor 22 with respect to the mounting opening 16 shown in FIG.

Further, in the present embodiment, when the internal connection terminal portion 44A is connected to the internal conductor 22 by mounting the housing portion 32 in the mounting opening 16, the relay portion 44B of the second terminal portion 44 shown in FIG. 8A is connected. The contact portions 36E and 36F (see FIG. 8B) of the second housing portion 36 come into contact with each other from the side opposite to the connector mounting direction (see arrow X1). Therefore, even if an insertion resistor acts on the second terminal portion 44 when the internal connection terminal portion 44A and the internal conductor 22 shown in FIG. 2 are connected, the deformation of the second terminal portion 44 is caused by the contact portions 36E and 36F. (See FIGS. 8A and 8B).

Further, in the present embodiment, the relay portion 44B provided between the second relay connection portion 44C and the internal connection terminal portion 44A shown in FIG. 5 is the second relay when viewed in the connector mounting direction (arrow X1 direction). Elastic deformation is possible when a load in a direction that changes the relative position between the connection portion 44C and the internal connection terminal portion 44A is applied. Therefore, even if the positional relationship between the internal connection terminal portion 44A and the internal conductor 22 shown in FIG. 1 and the like is slightly deviated due to the influence of manufacturing tolerance, assembly tolerance, etc., the deviation is caused by the relay portion 44B which is an elastic portion. It can be absorbed by the elastic deformation (see FIG. 5). Thereby, the internal connection terminal portion 44A and the internal conductor 22 can be easily and surely connected.

Further, in the present embodiment, since the relay portion 44B shown in FIG. 5 also serves as the elastic portion, even if the elastic portion is provided in the second terminal portion 44, it is possible to suppress the increase in size of the second terminal portion 44. it can.

As described above, according to the present embodiment, the assembling workability is good and it is possible to easily cope with the change of the connector connection position in the electronic device 10.

Further, in the present embodiment, as shown in FIGS. 3A and 3B, the separation distance L1 between the external connection terminal portions 42A is set shorter than the separation distance L2 between the internal connection terminal portions 44A. Therefore, the external device 100 connected to the external connection terminal portion 42A shown in FIG. 1 can be miniaturized, and the portion of the electronic device 10 to which the external device 100 is connected can be miniaturized. ..

Other configurations are the same as those of the second terminal portion 44 shown in FIG. Therefore, the same components as those of the second terminal portion 44 shown in FIG. 5 are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 9, in the relay unit 60A, the position of the second relay connection unit 44C and the position of the internal connection terminal unit 44A when viewed in the connector mounting direction (see arrow X1) are different from each other. It is provided between the relay connection portion 44C and the internal connection terminal portion 44A. The relay portion 60A is provided with a spring portion 60U as an elastic portion in the intermediate portion in the axial direction thereof. The spring portion 60U is formed in a U shape in which the side in the connector removal direction (see arrow X2) is open. The spring portion 60U is elastically deformable when a load in a direction that changes the relative position between the second relay connection portion 44C and the internal connection terminal portion 44A is applied in the connector mounting direction (see arrow X1).

In this modification, even if the positional relationship between the internal connection terminal portion 44A and the internal conductor 22 (see FIG. 1) is slightly deviated due to the influence of manufacturing tolerance or the like, the deviation can be easily caused by the elastic deformation of the spring portion 60U. Can be absorbed.
