However, in the structure of Patent Document 1, since the connecting portion between each of the plurality of contacts and the wiring board is covered by a shell, it is considered difficult to confirm the connection status between the contacts and the wiring board.

The present invention has been made in view of the above, and it is an object of the present invention to provide a connector that can shield electromagnetic noise while also allowing easy confirmation of the connection status between contacts and a wiring board.

In order to achieve the above object, a connector according to an embodiment of the present disclosure is a connector mounted on a board and arranged in one direction corresponding to each of a plurality of signal transmission members provided on a connection target. a plurality of conductive contacts, an insulating housing holding the plurality of contacts, a conductive shell attached to the housing so as to cover the housing, and a conductive shell closed so as to overlap with the shell. a conductive cover member attached to the conductive cover member so as to be able to switch between a state of the contact and a state of being open with respect to the shell, and the shell is located at a position corresponding to a joint portion of the plurality of contacts with the substrate. The cover member has an opening, and when the cover member is opened with respect to the shell, the joint portions of the plurality of contacts with the substrate are exposed to the outside.

According to the connector according to the present disclosure, since the opening is provided in the shell at a position corresponding to the joint portion of the plurality of contacts with the board, the joint portion is exposed to the outside when the cover member is opened with respect to the shell. be exposed. Therefore, by opening the cover member, it becomes possible to check the joint portion between the contact and the substrate from the outside. On the other hand, when the cover member is closed, the housing is covered by the shell and the cover member, so that external electromagnetic noise can be shielded. Therefore, according to the above connector, it is possible to easily check the connection status between the contacts and the wiring board while being able to shield electromagnetic noise.

In one form, the cover member may have an elastic portion that can be pressed against the shell in the closed state.

According to the above-mentioned connector, when the cover member is closed, the elastic portion can press the shell. With such a structure, it is possible to improve the reliability of the electrical connection between the cover member and the shell when the cover member is closed, thereby increasing the reliability of shielding electromagnetic noise.

In one form, the cover member can be switched between a closed state and an open state by rotating relative to the shell about a rotation axis extending in the same direction as the arrangement direction of the plurality of contacts. It can be made into an embodiment.

According to the above connector, the cover member can be switched between the closed state and the open state by rotating with respect to the shell. With such a configuration, the space required for moving the cover member can be reduced, and the device including this connector can be downsized.

In one form, the rotation shaft may be provided closer to a receptacle provided in the housing and into which the connection object is inserted than the opening.

According to the connector described above, the cover member rotates about the rotation shaft provided closer to the insertion port than the opening. With such a structure, the rotation of the cover member can be reduced even when the cover member is opened and the joint portions of the plurality of contacts with the substrate are confirmed using the opening.

In one embodiment, the cover member may include a restriction portion that restricts further rotation by coming into contact with the shell when the cover member rotates relative to the shell and opens.

According to the above-described connector, when the cover member rotates, the restricting portion comes into contact with the shell, thereby restricting further rotation. With such a configuration, damage to the cover member or the shell due to excessive rotation of the cover member can be prevented.

According to the present disclosure, a connector is provided that is capable of shielding electromagnetic noise and that allows easy confirmation of the connection status between contacts and a wiring board.

[Body configuration]
Next, the configuration of the main body 100 will be described in more detail with reference to FIGS. 1 to 9. Main body 100 includes a housing 110, a plurality of contacts 120, and a shell 130.

As shown in FIG. 9, the housing 110 is an insulating member and has a rectangular parallelepiped shape. The housing 110 may be formed by resin molding, for example. A housing space 111 that can receive the signal transmission medium 3 is provided within the housing 110 . Therefore, an insertion port 112 for the signal transmission medium 3 is provided in the front part of the housing 110 so as to communicate with the housing space 111.

The insertion port 112 is a slit-shaped opening surrounded by the bottom wall 113, the top wall 114, the rear wall 115, and a pair of side walls 116 of the housing 110. The insertion port 112 extends along the width direction (Y-axis direction) of the housing 110. The top wall portion 114 extends between the insertion port 112 and the rear wall portion 115.

In particular, as shown in FIG. 9, the tip portion 121 of the contact 120 is located within the accommodation space 111 of the housing 110. When the signal transmission medium 3 is inserted into the accommodation space 111, the tip portion 121 is physically and electrically connected to the signal line 3b of the signal transmission medium 3. The base end portion 122 of the contact 120 extends to the outside of the rear wall portion 115 by penetrating the rear wall portion 115 located on the opposite side from the insertion port 112 . When the connector 1 is mounted on the circuit board 2, the base end portion 122 is electrically and physically connected to a signal electrode (not shown) on the circuit board 2, for example, by soldering. That is, the base end portion 122 of the contact 120 and the vicinity thereof correspond to the joint portion between the contact 120 and the circuit board 2.

The shell 130 is conductive and suppresses leakage of electromagnetic waves from the contacts 120 to the outside of the connector 1, and also prevents noise from being mixed into the electrical signal transmitted by the contacts 120 due to electromagnetic waves from outside the connector 1. It is configured to suppress this. That is, the shell 130 functions as a noise shielding member. The shell 130 may be, for example, a metal member formed by bending.

The pair of bent portions 131a cover the front edge of the housing 110 to such an extent that they do not overlap the insertion port 112 of the housing 110.

The plurality of ground terminals 131b are arranged between the pair of bent portions 131a so as to be adjacent to each other in the width direction (Y-axis direction) of the top plate 131. As particularly shown in FIGS. 9 and 10, the plurality of ground terminals 131b are bent along the front edge of the housing 110 until they reach the inside of the insertion port 112. When the signal transmission medium 3 is inserted into the housing space 111, the plurality of ground terminals 131b are physically and electrically connected to a ground transmission path (not shown) of the signal transmission medium 3.

The pair of through holes 131c are lined up in the width direction (Y-axis direction) of the top plate 131, as shown in FIGS. 1, 3, and the like. The pair of through holes 131c correspond to the through holes 117 provided in the top wall portion 114 of the housing 110, respectively. Therefore, as particularly shown in FIG. 9, each of the pair of through holes 131c communicates with the corresponding through hole 117.

The opening 131d is one through hole extending along the width direction (Y-axis direction) of the top plate 131, as shown in FIGS. 3 and 4. The opening 131d is provided at a position corresponding to the base end portion 122 of the contact 120 in plan view when the connector 1 is assembled (see FIG. 10). The opening 131d is formed to overlap all of the plurality of base end portions 122.

As shown in FIGS. 9 and 10, the bottom plate 132 is arranged to face the top plate 131 in the height direction (Z-axis direction) of the main body 100. The bottom plate 132 is integrally connected to the top plate 131 via a pair of connecting parts 135.

When the signal transmission medium 3 is inserted into the housing space 111, the main portion 132a of the bottom plate 132 is physically and electrically connected to a ground transmission path (not shown) of the signal transmission medium 3. As shown in FIG. 4, the main portion 132a is provided with a plurality of spring portions 132c that project upwardly from the surface of the main portion 132a. By providing the spring portion 132c, it is possible to improve the connection reliability between the main portion 132a and the ground transmission path when the signal transmission medium 3 is inserted into the accommodation space 111.

A plurality of bent pieces 132b are provided at the leading edge of the main portion 132a. The plurality of bent pieces 132b are bent toward the side away from the top plate 131 while protruding outward along the depth direction (X direction) of the main body 100. When the connector 1 is mounted on the circuit board 2, each of the plurality of bent pieces 132b is electrically and physically connected to a ground electrode (not shown) of the circuit board 2, for example, by soldering.

The rear plate 133 covers the rear wall 115 of the housing 110 at a position away from the rear wall 115, as shown in FIGS. 9 and 10. Therefore, the base end portion 122 of the contact 120 is located in the space between the rear plate 133 and the rear wall portion 115. A plurality of bent pieces 133a are provided at the lower edge of the rear plate 133. The plurality of bent pieces 133a are bent from the rear plate 133 so as to protrude outward along the depth direction (X direction) of the main body 100.

The pair of side plates 134 each cover the side wall portion 116 of the housing 110. Since the pair of side plates 134 have a substantially mirror-symmetrical relationship with each other, only the configuration of one side plate 134 will be described below, and a description of the other side plate 134 will be omitted.

The side plate 134 is provided with a through hole 134a, as particularly shown in FIGS. 3 to 5. The through hole 134a may have a rectangular shape extending in the height direction (Z-axis direction) of the main body 100. The through hole 134a may be located closer to the insertion port 112 than the center of the side plate 134 in the depth direction (X-axis direction) of the main body 100.

A plurality of bent pieces 134b are provided at the lower edge of the side plate 134. The plurality of bent pieces 134b are bent from the side plate 134 so as to protrude outward along the width direction (Y direction) of the main body 100.

The through hole 134c may be located closer to the rear end (farther from the insertion port 112) than the center of the side plate 134 in the depth direction (X-axis direction) of the main body 100. Note that, instead of the through hole 134c, a recessed portion recessed toward the inside may be provided.

An auxiliary plate 134d is provided at the lower end edge of the side plate 134 and extends in a bent manner from the lower end edge. That is, the auxiliary plate 134d is integrally connected to the side plate 134 via the bent portion 134e. The auxiliary plate 134d faces the side plate 134 in the width direction (Y-axis direction) of the main body 100. When the connector 1 is mounted on the circuit board 2, the auxiliary plate 134d and the bent portion 134e may be electrically and physically connected to a ground electrode (not shown) of the circuit board 2, for example, by soldering. good. That is, the bent portion 134e may function as a fixing portion that is fixed to the circuit board 2, which is another member.

A rotation shaft 134f is provided on the side edge of the auxiliary plate 134d. The rotation shaft 134f is a bent piece obtained by bending a part of the auxiliary plate 134d, and extends in the width direction (Y-axis direction) of the main body 100 from the auxiliary plate 134d toward the side plate 134. The tip of the rotation shaft 134f is inserted into the through hole 134a. That is, the tip of the rotation shaft 134f is engaged with the through hole 134a.

In particular, as shown in FIG. 5, the tip of the rotation shaft 134f may penetrate through the through hole 134a so as to approach the housing 110. Therefore, similarly to the through hole 134a, the rotation shaft 134f may be located closer to the insertion port 112 than the center portion of the side plate 134 in the depth direction (X-axis direction) of the main body 100.

Note that the tip of the rotating shaft 134f may be inclined so that the width thereof gradually decreases toward the tip. When the tip of the rotating shaft 134f has an inclination, a portion of the periphery of the rotating shaft 134f of the bent portion 134e facing the opposite side (a portion facing the top plate 131 side) may be configured to be inclined.

[Configuration of cover member]
Next, the structure of the cover member 200 will be described in more detail with reference to FIGS. 1, 2, and 6 to 10. Cover member 200 includes a main plate 210 , a pair of side plates 220 , a rear plate 230 , and a pair of regulating members 240 . The cover member 200 may be a metal member formed by bending, for example.

The main plate 210 extends in the width direction (Y-axis direction) of the cover member 200, as shown in FIGS. 1 and 2. When the cover member 200 overlaps the top plate 131 of the shell 130 (closed with respect to the main body 100), the main plate 210 covers most of the top plate 131 except for the area near the insertion port 112. There is.

As shown in FIGS. 1 and 6 to 8, the pair of side plates 220 each extend toward the main body 100 while being bent from both side edges of the main plate 210. A shaft hole 221, which is a through hole passing through the side plate 220, is provided at the tip of the side plate 220 (the end on the insertion port 112 side). In particular, as shown in FIGS. 1 and 3, a rotation shaft 134f provided in the main body 100 (shell 130) is inserted into the shaft hole 221. Therefore, the cover member 200 is attached to the main body 100 (shell 130) so as to be rotatable around the rotation axis 134f.

In the vicinity of the rear end portion 222 of the side plate 220, a protrusion 222a that protrudes inward from the inner wall surface of the side plate 220 is provided, particularly as shown in FIG. As shown in FIG. 1, when the cover member 200 overlaps the top plate 131 (closed with respect to the main body 100), the protruding portion 222a is accommodated in the through hole 134c. engage with. For example, the protruding portion 222a may be formed by embossing the side plate 220. The protrusion height of the protrusion 222a may be equal to or less than 1/2 of the thickness of the side plate 220.

As particularly shown in FIGS. 7 and 8, the rear plate 230 extends toward the main body 100 while being bent from an end extending in the width direction (Y-axis direction) on the rear end side of the main plate 210. Further, the rear plate 230 covers the rear plate 133 of the shell 130, as shown in FIGS. 9 and 10.

The rear plate 230 is provided with a plurality of pressing portions 231 that project obliquely from the surface of the rear plate 230 toward the main plate 210 side. The pressing portion 231 can be formed, for example, by cutting and bending a part of the rear plate 230. The pressing portion 231 has elasticity because it is cut and bent into small pieces. In the state where the cover member 200 overlaps the top plate 131 (closed state with respect to the main body 100), the pressing portion 231 comes into contact with the shell 130 and presses the shell 130. That is, the provision of the pressing portion 231 on the cover member 200 increases the reliability of the connection between the cover member 200 and the shell 130 when the cover member 200 overlaps the top plate 131 (closed with respect to the main body 100). You can increase your sexuality.

As shown in FIGS. 6 to 9, the pair of regulating members 240 are, for example, metal pieces obtained by cutting and bending a portion of the main plate 210. The pair of regulating members 240 are configured to be able to lock the signal transmission medium 3 inserted into the insertion port 112 so as to restrict removal of the signal transmission medium 3 from the housing 110 (details will be described later). do).

The pair of regulating members 240 are lined up in the width direction (Y-axis direction) of the main plate 210. In particular, as shown in FIGS. 1, 2, and 9, when the cover member 200 overlaps the top plate 131 (closed with respect to the main body 100), each of the pair of regulating members 240 has a corresponding through hole. 117, 131c. That is, in this state, the pair of regulating members 240 are respectively locked in the corresponding through holes 117 and 131c. At this time, the tip of the regulating member 240 is located within the accommodation space 111.

The regulating member 240 has an inclined portion 240a on the insertion port 112 side. The inclined portion 240a is formed such that the width (length in the X-axis direction) of the regulating member 240 gradually decreases from the insertion port 112 side toward the rear end (the side far from the insertion port 112). There is. As a result, the regulating member 240 has a so-called tapered shape. Further, by providing the inclined portion 240a, the protrusion length (length in the Z-axis direction) of the regulating member 240 from the main plate 210 is increased from the insertion port 112 side to the rear end (the side far from the insertion port 112). ) gradually increases in size. Furthermore, a notch 240b may be provided at the end of the regulating member 240 on the opposite side from the insertion port 112 side where the inclined portion 240a is provided so as to have a tapered shape. This notch 240b has a function of restricting movement (especially removal) of the signal transmission medium 3 when it is attached to the connector 1.

[How to attach the cover member to the main body]
Next, a method for attaching the cover member 200 to the main body 100 will be explained. As described above, the rotation shaft 134f provided in the shell 130 of the main body 100 is inserted into the shaft hole 221 provided in the side plate 220 of the cover member 200. Therefore, first, the auxiliary plate 134d is inclined with respect to the bent portion 134e so that the auxiliary plate 134d moves away from the side plate 134 toward the tip of the auxiliary plate 134d. Thereby, the rotation shaft 134f is located outside the through hole 134a.

Thereafter, by moving the cover member 200 closer to the main body 100 from around the top plate 131, the side plate 220 pushes the auxiliary plate 134d outward while coming into contact with the rotation shaft 134f. By bringing the cover member 200 closer to the main body 100, when the tip of the rotating shaft 134f overlaps with the shaft hole 221 of the side plate 220, the spring property of the auxiliary plate 134d causes the auxiliary plate 134d and the rotating shaft 134f to return to their original positions. Trying to go back. As a result, the tip of the rotating shaft 134f is naturally inserted into the shaft hole 221.

Thereafter, as shown in FIG. 5, by pushing the rotation shaft 134f into the through hole 134a, the rotation shaft 134f is inserted into the shaft hole 221 and engaged with the through hole 134a. Thereby, the cover member 200 is attached to the main body 100 so as to be rotatable around the rotation axis 134f. In this way, the connector 1 is completed.

Note that when attaching the cover member 200 to the main body 100, the cover member 200 approaches the main body 100 while the rear end portion 222 of the side plate 220 of the cover member 200 is slightly deformed, and the protruding portion 222a is connected to the through hole 134c. When they overlap, they enter into the through hole 134c and are locked in the through hole 134c. Thereby, even if some external force acts on the cover member 200, the through hole 134c and the protrusion 222a can maintain the closed state in which the cover member 200 overlaps the main body 100.

Note that the above-mentioned attachment method is an example, and is not limited to the above-mentioned method.

[How to attach the signal transmission medium to the electrical connector]
Next, a method for attaching the signal transmission medium 3 to the connector 1 will be described with reference to FIGS. 10 and 11. FIG. 10 shows the state before the signal transmission medium 3 is attached to the connector 1, and FIG. 11 shows the state after the signal transmission medium 3 is attached.

As shown in FIG. 11, when the signal transmission medium 3 is inserted into the accommodation space 111 from the insertion port 112, the plurality of signal lines 3b of the signal transmission medium 3 are physically and electrically connected to the corresponding contacts 120. Connected. Further, a ground transmission path (not shown) of the signal transmission medium 3 is physically and electrically connected to the ground terminal 131b and the main portion 132a of the bottom plate 132.

While the signal transmission medium 3 is being inserted, the end surface of the signal transmission medium 3 comes into contact with the inclined portion 240a of the regulating member 240. When the signal transmission medium 3 is further moved into the accommodation space 111 in this state, the leading end of the signal transmission medium 3 is elastically displaced so as to slip below the regulating member 240 along the inclined portion 240a.

When the signal transmission medium 3 is further inserted, the tip of the signal transmission medium 3 passes the regulating member 240, and the elastic displacement of the tip of the signal transmission medium 3 is released and returns to its original shape, so that the tip of the regulating member 240 passes the regulating member 240. It enters the notch 3c of the transmission medium 3.

In this way, since the tip of the regulating member 240 is located within the notch 3c of the signal transmission medium 3, the tip of the regulating member 240 restricts removal of the signal transmission medium 3 from the connector 1. In particular, when the restriction member 240 is provided with the notch 240b, the restriction member 240 that has entered the notch 3c of the signal transmission medium 3 moves in the direction in which the signal transmission medium 3 is removed from the connector 1 (X-axis negative direction). The movement of people can be regulated. Therefore, removal of the signal transmission medium 3 from the connector 1 can be reliably regulated.

Note that when removing the signal transmission medium 3 from the connector 1, it is necessary to move the tip of the regulating member 240 from the notch 3c of the signal transmission medium 3. Therefore, after moving the regulating member 240 by rotating the cover member 200, the signal transmission medium 3 is removed.

[Checking the contact bonding status by rotating the cover member]
Next, a state in which the cover member 200 is rotated relative to the main body 100 will be described with reference to FIGS. 12 and 13. The rotation of the cover member 200 is used not only to move the regulating member 240 when removing the signal transmission medium 3 from the connector 1 as described above, but also to check the connection status of the connector 1, especially the contacts 120, to the circuit board 2. It will be held in

As shown in FIGS. 12 and 13, the cover member 200 is rotatable around the rotation axis 134f until the end 210a of the main plate 210 on the insertion port 112 side comes into contact with the surface of the top plate 131 of the shell 130. has been done. In other words, the rotation of the cover member 200 is regulated by the contact between the end 210a of the main plate 210 and the top plate 131 of the shell 130. The end portion 210a of the main plate 210 functions as a restriction portion that restricts rotation of the cover member 200 by a predetermined angle or more.

When the cover member 200 is rotated to a certain extent with respect to the main body 100, the opening 131d provided in the top plate 131 of the shell 130 can be confirmed from the outside in plan view, as shown in FIG. The base end portion 122 of the contact 120 is arranged below the opening 131d. Therefore, when the cover member 200 is rotated, the base ends 122 of the contacts 120 disposed at the lower part of the shell 130 are exposed to the outside through the opening 131d with the connector 1 mounted on the circuit board 2. I can do it.

Note that a configuration may be provided to maintain the rotational position of the cover member 200 with respect to the main body 100 in the state shown in FIGS. 12 and 13. For example, when the cover member 200 is attached to the main body 100, the lower ends (ends on the circuit board 2 side) of the pair of side plates 220 of the cover member 200 interfere with the pair of side plates 134 of the shell 130. For example, the bending angle of the side plate 220 may be adjusted as shown in FIG. In such a configuration, when the cover member 200 is rotated from a state where the cover member 200 overlaps the top plate 131 (closed state with respect to the main body 100), the lower end 220a of the side plate 220 interferes with the side plate 134. As a result, a frictional force is generated in a direction that prevents the cover member 200 from moving. Utilizing this, a configuration may be adopted in which the cover member 200 is prevented from rotating due to gravity (in particular, rotating in the closing direction).

[Effect]
In the connector 1 described in the above embodiment, the opening 131d is provided in the shell 130 at a position corresponding to the joint portion of the plurality of contacts 120 with the circuit board 2. Therefore, when the cover member 200 is opened with respect to the shell 130 (main body 100), the joint portion formed at the base end portion 122 of the contact 120 and connected to the circuit board 2 is exposed to the outside. Therefore, by opening the cover member 200, it becomes possible to check the joint portion between the contact 120 and the circuit board 2 from the outside. On the other hand, when the cover member 200 is closed, the housing 110 is covered by the shell 130 and the cover member 200, so that external electromagnetic noise can be shielded. Therefore, according to the connector 1 described above, it is possible to easily check the connection status between the contacts 120 and the circuit board 2 while being able to shield electromagnetic noise.

In addition, the cover member 200 of the connector 1 described above has an elastic part that can be pressed against the shell 130 in the closed state, specifically, a pressing part 231 that projects from the surface of the rear plate 230 at an angle toward the main plate 210. has. With this configuration, when the cover member 200 is closed, the pressing portion 231 presses the shell 130, so that the reliability of the electrical connection between the cover member 200 and the shell 130 can be increased. , it is possible to improve reliability regarding shielding of electromagnetic noise.

Furthermore, the cover member 200 of the connector 1 can be switched between a closed state and an open state by rotating relative to the shell 130 about a rotation shaft 134f extending in the same direction as the arrangement direction of the plurality of contacts 120. Switchable. With such a configuration, the space required for moving the cover member 200 can be reduced, and the device including this connector 1 can be downsized.

Further, a rotation shaft 134f for rotating the cover member 200 is provided closer to the insertion port 112 of the housing 110 than the opening 131d. That is, the cover member 200 rotates about the rotation shaft 134f provided closer to the insertion port 112 than the opening 131d. With such a structure, even when the cover member 200 is opened and the joint portion between the plurality of contacts 120 and the circuit board 2 is checked through the opening 131d, the rotation of the cover member 200 can be reduced. can.

Furthermore, when the cover member 200 rotates relative to the shell 130 and opens, the cover member 200 includes a restriction portion that comes into contact with the shell 130 to restrict further rotation. Specifically, further rotation is restricted by the end portion 210a of the main plate 210 coming into contact with the shell 130. Therefore, damage to the cover member 200 or the shell 130 due to excessive rotation of the cover member 200 can be prevented.

[others]
Although the embodiments according to the present disclosure have been described above, various modifications may be made to the above embodiments within the scope of the gist of the present invention.

For example, the shape of the connector 1 is not limited to that described in the above embodiment. The number of contacts 120 provided in the connector 1 can also be changed as appropriate.

Further, the shape of the cover member 200 can be changed as appropriate. For example, when the cover member 200 is configured to rotate relative to the main body 100, the position of the rotation shaft 134f can be changed as appropriate. When the cover member 200 is closed, electromagnetic noise can be sufficiently shielded, and when the cover member 200 is open, the joint portion between the contact 120 and the circuit board 2 is exposed to the outside using the opening 131d. The shape of the cover member 200 and the position of the rotation shaft 134f can be changed as appropriate as long as the state can be confirmed from the above.

Further, the cover member 200 does not need to be configured to rotate about the rotation axis 134f with respect to the main body 100 (shell 130). For example, by sliding the cover member 200 with respect to the main body 100, the above-mentioned closed state (a state that shields electromagnetic noise) and open state (a state where the joints between the contacts 120 and the circuit board 2 can be confirmed from the outside) It is also possible to have a configuration that switches between the two states. Even with this configuration, as with the connector 1 described in the above embodiment, it is possible to easily check the connection status between the contacts and the wiring board while shielding electromagnetic noise. .

Furthermore, the shape of the opening 131d is not limited to the shape of the connector 1 described above. As described above, when the cover member 200 is open, it is sufficient that the joint portion between the contact 120 and the circuit board 2 can be confirmed from the outside using the opening 131d. Therefore, the opening 131d does not need to be formed by only one opening; for example, by combining a plurality of openings, the opening 131d can be formed so that the joint portion between the contact 120 and the circuit board 2 can be confirmed from the outside. The shape can be changed as appropriate.

Further, the configuration of the pressing portion 231 can also be changed as appropriate. For example, the position where the pressing part 231 is provided may be a different position from the rear plate 230. Further, the number of pressing portions 231, etc. can also be changed as appropriate. Furthermore, a configuration may be adopted in which the pressing portion 231 is not provided. Further, the region where the opening 131d is formed in the shell 130 may be a range where all of the joint portions between the plurality of contacts 120 and the circuit board 2 are visible from the outside, or a region where a portion of the joint portions is visible from the outside. It may be a range that is visible from the outside.
