Description

The present disclosure relates to a cover device for electronic components.

Conventionally, a throttle cover is known which covers a motor terminal protruding from a motor arranged inside the throttle and also includes a terminal stand for supplying power to the motor terminal (see, for example, Patent Document 1).

The terminal base has a concave hole. Inside the hole, a pressure welding terminal that supplies power from the outside to the motor terminal is provided. The pressure welding terminal is plate-shaped and has a wall portion and a pressure welding portion. The wall portion is formed in a U shape along the inner peripheral surface of the terminal base, and has a gap into which the motor terminal is inserted between the portions facing each other. When the motor terminal is inserted into the gap between the wall portions, the pressure welding portion makes the pressure welding terminal and the motor terminal conductive by pressing the motor terminal against the wall portion.

JP-A-2002-295272

By the way, like the throttle cover described in Patent Document 1, there is a cover device that supplies power to electronic components such as a motor. The cover device is a power supply unit that covers the power supply terminal corresponding to the motor terminal and supplies power to the power supply terminal. The cover device includes a terminal connection portion corresponding to a pressure welding terminal.

The terminal connection portion has a first wall portion and a second wall portion, each of which faces each other. Further, the terminal connection portion has a pressure contact portion formed by folding back from the end portion of the second wall portion and extending toward the first wall portion. When the motor terminal is inserted into the gap between the first wall portion and the second wall portion, the pressure welding portion directs the power supply terminal toward the first wall portion in order to ensure continuity between the power supply terminal and the terminal connection portion. It is desirable to press with a force equal to or higher than the predetermined target value.

The force with which the pressure contact portion pushes the power supply terminal is generated by the deformation of the pressure contact portion when the power supply terminal is inserted into the gap between the first wall portion and the second wall portion. Further, the force with which the pressure welding portion pushes the power feeding terminal is determined by the amount of displacement of the pressure welding portion in the plate thickness direction, which is deformed by inserting the power feeding terminal.

In order to press the power supply terminal against the first wall with a force equal to or greater than the predetermined target value, the shape of the terminal connection and the size in the plate thickness direction depend on the size of the power supply terminal in the plate thickness direction. Set. However, when the size of the power supply terminal in the plate thickness direction has a plurality of types, the shape of the terminal connection portion and the size in the plate thickness direction must be changed for each type of the power supply terminal. This is not preferable because it increases the types of terminal connection portions and causes deterioration of production efficiency.

It is an object of the present disclosure to provide a cover device capable of adjusting the force with which the terminal connection portion pushes the power feeding terminal even if the same terminal connection portion is used.

This embodiment describes an example applied to the throttle device 1 for adjusting the amount of air sent by the cover device 10 to the engine of the vehicle. The throttle device 1 is arranged in a vehicle, and under the control of an ECU (Engine Control Unit) (not shown), adjusts the intake amount of air sent into the engine according to the amount of depression of the accelerator pedal (not shown).

As shown in FIG. 1, the throttle device 1 includes a throttle body 100 which is a housing of the throttle device 1, a throttle valve 110 for adjusting the amount of air sent to the engine, and a shaft 120 for rotating the throttle valve 110. Further, the throttle device 1 includes a motor 90 which is an electronic component that rotates the shaft 120, a gear train 130 that transmits the rotation of the motor 90 to the shaft 120, and a valve opening sensor 140 that measures the opening degree of the throttle valve 110. Be prepared. In the throttle device 1, a cover device 10 that covers the power supply terminal 91 protruding from the motor 90 is attached to the throttle body 100.

The throttle body 100 forms the main body of the throttle device 1. Inside the throttle body 100, a cylindrical air passage 101 through which air sucked from the outside flows and a motor chamber 102 accommodating the motor 90 are formed. Further, the throttle body 100 is formed with an opening 103 communicating with the motor chamber 102.

The throttle valve 110 is a regulating valve that adjusts the amount of air flowing through the air passage 101. The throttle valve 110 is arranged in the air passage 101 and is fixed to the shaft 120. The opening degree of the throttle valve 110 is adjusted by rotating the throttle valve 110 integrally with the shaft 120 as the shaft 120 rotates.

The gear train 130 includes a drive gear 131, an intermediate gear 132, and a valve gear 133. The drive gear 131 is attached to the motor 90 and rotates as the motor 90 rotates. The intermediate gear 132 meshes with the drive gear 131 and the valve gear 133, and transmits the driving force of the drive gear 131 to the valve gear 133. The valve gear 133 is attached to one end of the shaft 120, and rotates the shaft 120 by a driving force transmitted from the intermediate gear 132.

The valve opening sensor 140 is an angle detection sensor that measures the opening degree of the throttle valve 110 by detecting the rotational position of the valve gear 133.

A part of the valve opening sensor 140 is arranged inside the valve gear 133, and detects the rotation position of the valve gear 133 by detecting the rotation position of a permanent magnet (not shown) attached to the inner circumference of the valve gear 133. .. The valve opening sensor 140 is connected to an ECU (not shown), and transmits the measured opening degree of the throttle valve 110 to the ECU.

In the present embodiment, the valve opening sensor 140 is a Hall type sensor using a Hall IC (Integrated Circuit), and is composed of a non-contact type position sensor. In addition to the Hall type sensor, the valve opening degree sensor 140 may be composed of a non-contact type position sensor such as an MR type sensor or an inductive type sensor, or a contact type position sensor such as a potentiometer type sensor.

The motor 90 is arranged in the motor chamber 102 and is a power source that receives power from the outside and generates torque for rotating the shaft 120. The motor 90 has a power supply terminal 91 that is a power receiving unit, and a rotating shaft 92 that outputs the torque of the motor 90 to the outside. The power supply terminal 91 and the rotating shaft 92 project from the opening 103 toward the outside of the motor chamber 102.

A rotation shaft 92 of the motor 90 is attached to the drive gear 131, and the motor 90 is rotated by the throttle valve 110 by the torque amplified by the gear train 130. In this way, the motor 90 supplies the driving force for rotating the throttle valve 110. The power supply path to the motor 90 will be described later.

Next, the cover device 10 will be described. The cover device 10 covers the opening 103 and conducts electric power from the outside to the valve opening sensor 140 and the motor 90. As shown in FIG. 2, the cover device 10 has a tray-like shape in which a part is formed in a mesh shape, and is made of resin. The cover device 10 is attached to the throttle body 100 so as to cover the opening 103, the gear train 130, the rotating shaft 92, and the power feeding terminal 91. Further, the cover device 10 has a sensor accommodating portion 11, a connector portion 12, and two terminal inserting portions 20.

The sensor accommodating portion 11 is an accommodating portion that supports and accommodates the valve opening degree sensor 140. As shown in FIG. 1, the sensor accommodating portion 11 is formed at a position facing the valve gear 133.

The connector unit 12 is an interface for electrically connecting the ECU, the external power supply, and the throttle device 1. Specifically, one end of the connector portion 12 is electrically connected to a signal cable extending from the ECU and a power cable extending from a battery mounted on the vehicle. Further, the other end side of the connector portion 12 is electrically connected to the valve opening degree sensor 140 and the terminal insertion portion 20.

As shown in FIG. 2, the two terminal insertion portions 20 are both located at positions separated from the valve opening degree sensor 140, and are arranged apart from each other. Further, the two terminal insertion portions 20 project toward the throttle body 100. In the present embodiment, the terminal insertion portion 20 is made of resin.

The terminal insertion portion 20 is formed with a terminal insertion hole 22 having a terminal insertion port 21 which is an opening portion into which the power supply terminal 91 is inserted. When the cover device 10 is attached to the throttle body 100, the terminal insertion portion 20 is inserted with the power supply terminal 91. Further, as shown in FIG. 3, the terminal insertion portion 20 is provided with a plate-shaped conductive member 30 and a plate-shaped terminal connection portion 40 inside the terminal insertion hole 22. In the following description, in the present embodiment, the opening direction of the terminal insertion hole 22 and the direction in which the power supply terminal 91 is inserted into the terminal insertion hole 22, that is, the vertical direction of the paper surface in FIG. 3 is referred to as the first direction DR1. Call. Further, in the present embodiment, the direction orthogonal to the first direction DR1 and the plate thickness direction of the terminal connecting portion 40, that is, the left-right direction on the paper surface of FIG. 3 is referred to as the second direction DR2. Further, in the present embodiment, the direction orthogonal to the first direction DR1 and the second direction DR2 is referred to as a third direction DR3.

As shown in FIGS. 3 and 4, the terminal insertion hole 22 includes a plurality of inner peripheral surfaces and is formed in a rectangular parallelepiped shape. Specifically, the terminal insertion hole 22 has a first inner peripheral surface 23 located on one side of the second direction DR2, a second inner peripheral surface 24 located on the other side of the second direction DR2, and a first inner peripheral surface. It has a third inner peripheral surface 25 that is connected to the surface 23 and the second inner peripheral surface 24 and forms the bottom surface of the terminal insertion hole 22.

Of the plurality of inner peripheral surfaces, the first inner peripheral surface 23 and the second inner peripheral surface 24 face each other. Further, the first inner peripheral surface 23 and the second inner peripheral surface 24 are formed so as to extend along the first direction DR1 and the third direction DR3. Further, the second inner peripheral surface 24 has an adjusting unit 50, which will be described later. The third inner peripheral surface 25 is formed so as to extend along the second direction DR2 and the third direction DR3.

In the terminal insertion hole 22, a conductive member 30 bent along the shapes of the first inner peripheral surface 23 and the third inner peripheral surface 25 is arranged. Further, in the terminal insertion hole 22, a terminal connecting portion 40 bent along the shapes of the first inner peripheral surface 23, the second inner peripheral surface 24, and the third inner peripheral surface 25 is arranged.

The conductive member 30 is formed of a conductive metal plate that conducts power from the battery to the terminal connection portion 40. One end side of the conductive member 30 extends to the connector portion 12 and is electrically connected to the connector portion 12. Further, the other end side of the conductive member 30 is fitted and positioned with the protrusion boss portion 26 located near the opening which is the other end portion of the terminal insertion hole 22 in the first direction DR1.

Further, a part of the conductive member 30 is exposed on the first inner peripheral surface 23 and the third inner peripheral surface 25, and is electrically conductively connected to the terminal connecting portion 40. Specifically, in the conductive member 30, a portion arranged on the first inner peripheral surface 23 and a portion arranged on the third inner peripheral surface 25 are crimped to and connected to the terminal connecting portion 40. The conductive member 30 conducts the electric power supplied from the connector portion 12 to the terminal connecting portion 40.

As shown in FIGS. 3 and 4, the terminal connection portion 40 is formed of a flexible and bent conductive metal plate and has a plane extending in the third direction DR3. The terminal connection portion 40 is connected to the conductive member 30, presses the power supply terminal 91 inserted into the terminal insertion hole 22, and supplies the electric power supplied from the conductive member 30 to the power supply terminal 91. is there.

The terminal connection portion 40 includes a first wall portion 41 located on one side of the second direction DR2, a second wall portion 42 located on the other side of the second direction DR2, and a first wall portion 41 and a second wall portion. It is connected to 42 and has a third wall portion 43 located on one side of the first direction DR1. Further, the terminal connecting portion 40 has an upper surface portion 44 that is connected to the other end portion of the first wall portion 41 of the first direction DR1 and extends along the shape of the conductive member 30. The terminal connection portion 40 is positioned by fitting the upper surface portion 44 together with the conductive member 30 with the protrusion boss portion 26.

Further, the terminal connection portion 40 is connected to the other end of the first direction DR1 of the second wall portion 42, is folded back from the end portion, and is connected to one side of the first direction DR1 and one side of the second direction DR2. It has a pressure contact portion 45 formed so as to extend toward it. The pressure contact portion 45 is in contact with the first wall portion 41, and presses the power supply terminal 91 inserted between the pressure contact portion 45 and the first wall portion 41 against the first wall portion 41.

As shown in FIG. 3, the first wall portion 41 is arranged to face the portion of the conductive member 30 arranged on the first inner peripheral surface 23, and is formed along the shape of the conductive member 30. .. The first wall portion 41 is supported by the first inner peripheral surface 23 via the conductive member 30.

One end of the first wall 41 in the first direction DR1 is connected to one end of the third wall 43 in the second direction DR2. Further, the other end of the first wall portion 41 in the first direction DR1 is connected to the other end of the upper surface portion 44 in the second direction DR2.

The second wall portion 42 is arranged so as to face the second inner peripheral surface 24, and is formed along the shape of the second inner peripheral surface 24. The second wall portion 42 is supported by the second inner peripheral surface 24.

One end of the second wall 42 in the first direction DR1 is connected to the other end of the third wall 43 in the second direction DR2. Further, the other end of the first direction DR1 of the second wall portion 42 is connected to the other end of the first direction DR1 of the pressure contact portion 45. Further, the second wall portion 42 has a convex portion 60, which will be described later, that protrudes toward the second inner peripheral surface 24.

The third wall portion 43 is arranged to face the portion of the conductive member 30 arranged on the third inner peripheral surface 25, and is formed along the shape of the conductive member 30. Both ends of the second direction DR2 of the third wall portion 43 are connected to the first wall portion 41 or the second wall portion 42, respectively, as described above.

The pressure contact portion 45 is arranged so as to face the first wall portion 41. The pressure contact portion 45 extends from the other end of the first direction DR1 of the second wall portion 42 toward the first wall portion 41, and abuts on the first wall portion 41 with the first slope portion 46 and the first slope. It has a second slope portion 47 that folds back from the end portion of the portion 46 and extends toward the second wall portion 42 and abuts on the second wall portion 42. Further, the pressure contact portion 45 has a third slope portion 48 that is folded back from the end portion of the second slope portion 47 and extends toward the first wall portion 41.

The first slope portion 46 is formed so as to extend toward one side of the first direction DR1 and one side of the second direction DR2, and one end of the first direction DR1 corresponds to the first wall portion 41. It is in contact with it and is connected to the second slope portion 47. The second slope portion 47 is formed so as to extend from one end of the first slope portion 46 on one side of the first direction DR1 toward one side of the first direction DR1 and the other side of the second direction DR2. One end of the one-way DR1 is in contact with the second wall 42 and is connected to the third slope 48. The third slope portion 48 is formed so as to extend from one end of the first direction DR1 of the second slope portion 47 toward one side of the first direction DR1 and one side of the second direction DR2. One end of the one-way DR1 is not in contact with the first wall 41.

The size of the first direction DR1 of the first slope portion 46 is substantially the same as the size of the first direction DR1 of the second slope portion 47. The size of the first direction DR1 of the third slope portion 48 is smaller than the size of the first direction DR1 of the first slope portion 46 and the size of the first direction DR1 of the second slope portion 47. Further, in the pressure contact portion 45, even before the power supply terminal 91 is inserted into the terminal insertion hole 22, the portion where the first slope portion 46 and the second slope portion 47 are connected is the first wall portion 41. At the same time as abutting, the portion is formed so as to push the first wall portion 41 toward one side of the second direction DR2.

In the terminal connection portion 40 configured in this way, as shown in FIG. 5, when the power supply terminal 91 is inserted into the terminal insertion hole 22, the pressure contact portion 45 is deformed and the first slope portion 46 and the second slope portion 46 and the second are formed. The portion connected to the slope portion 47 moves to the other side of the second direction DR2. As a result, the terminal connection portion 40 allows the power feeding terminal 91 to be inserted between the pressure contact portion 45 and the first wall portion 41. At the same time, the terminal connection portion 40 presses the inserted power feeding terminal 91 against the first wall portion 41 by the elastic force generated by the deformation of the pressure contact portion 45. As described above, the power supply path to the motor 90 is formed by the pressure contact portion 45 pressing the power supply terminal 91 against the first wall portion 41.

As a result, the power supply terminal 91 is electrically connected to the conductive member 30 via the first wall portion 41. Therefore, the motor 90 can be rotated by the electric power supplied from the battery via the power feeding terminal 91 and the conductive member 30, and can generate torque for rotating the throttle valve 110. Therefore, the throttle device 1 can adjust the throttle valve 110 to a desired opening degree based on the amount of air intake required for the engine, which is determined according to the amount of depression of the accelerator pedal. Further, in the throttle device 1, the valve opening sensor 140 measures the opening degree of the throttle valve 110, and notifies the ECU of the measured opening degree of the throttle valve 110. Therefore, the throttle device 1 feedback-controls the rotation of the motor 90 based on the opening degree of the throttle valve 110 notified to the ECU.

Here, it is desirable that the elastic force that the terminal connecting portion 40 pushes the power feeding terminal 91 is a load equal to or more than a predetermined target value in order to secure the continuity between the power feeding terminal 91 and the conductive member 30. If the elastic force of the terminal connection portion 40 is lower than the target value, the throttle device 1 may have a problem in the continuity between the power supply terminal 91 and the conductive member 30, and the throttle valve 110 may not be adjusted to a desired opening degree. is there. Hereinafter, the load of the target value is also referred to as a required load.

The elastic force of the terminal connection portion 40 is the elastic force of the second direction DR2 of the pressure contact portion 45 when the pressure contact portion 45 is deformed by inserting the power supply terminal 91 between the pressure contact portion 45 and the first wall portion 41. Determined by the amount of displacement. Specifically, as shown in FIG. 6, the elastic force of the terminal connecting portion 40 has a correlation with the displacement amount of the pressure contact portion 45. The elastic force of the terminal connection portion 40 increases as the displacement amount of the pressure contact portion 45 increases.

The amount of displacement of the pressure contact portion 45 varies depending on the size of the second direction DR2 of the power feeding terminal 91 to be inserted. For example, a first power feeding terminal having a size of the second direction DR2 having a distance L1 or a second power feeding terminal having a size of the second direction DR2 having a distance L2 smaller than the distance L1 is inserted into the terminal insertion hole 22. The difference in elastic force of the terminal connection portion 40 in the case where the terminal connection portion 40 is used will be described with reference to FIG.

FIG. 6 shows a case where the pressure contact portion 45 is displaced by a distance L1 by inserting the first power supply terminal into the terminal insertion hole 22, and a case where the pressure contact portion 45 is displaced by inserting the second power supply terminal. The elastic force of the terminal connection portion 40 when only L2 is displaced is shown. Specifically, the displacement amount A in FIG. 6 indicates the displacement amount of the pressure contact portion 45 before the first power supply terminal and the second power supply terminal are inserted into the terminal insertion hole 22. The displacement amount B in FIG. 6 indicates the displacement amount of the pressure contact portion 45 after the second power feeding terminal is inserted into the terminal insertion hole 22. The displacement amount C in FIG. 6 indicates the displacement amount of the pressure contact portion 45 after the first power feeding terminal is inserted into the terminal insertion hole 22.

The terminal connection portion 40 is inserted into the terminal so that an elastic force is generated in the first wall portion 41 even before the first power supply terminal and the second terminal connection portion are inserted into the terminal insertion hole 22. It is provided in the part 20. Therefore, the pressure welding portion 45 is slightly displaced even before the first power feeding terminal and the second terminal connecting portion are inserted. Further, as shown in FIG. 6, the elastic force of the terminal connecting portion 40 before the first power feeding terminal and the second terminal connecting portion are inserted is the same.

As shown in FIG. 6, when the pressure contact portion 45 is displaced by the distance L1 due to the insertion of the first power feeding terminal into the terminal insertion hole 22, the elastic force of the terminal connection portion 40 becomes larger than the required load. On the other hand, when the pressure contact portion 45 is displaced by the distance L2 due to the insertion of the second power feeding terminal into the terminal insertion hole 22, the elastic force of the terminal connection portion 40 is smaller than the required load. If the elastic force of the terminal connecting portion 40 is smaller than the required load, the terminal connecting portion 40 may not be able to secure the continuity between the power feeding terminal 91 and the conductive member 30.

Here, in the throttle device 1 of the present embodiment, the convex portion 60 is provided on the second wall portion 42, and the adjusting portion 50 for adjusting the distance between the pressure contact portion 45 and the convex portion 60 is provided on the second inner peripheral surface 24. Has been done. The displacement amount of the pressure contact portion 45 when the power supply terminal 91 is inserted is the distance between the pressure contact portion 45 and the convex portion 60 before the power supply terminal 91 is inserted and after the power supply terminal 91 is inserted. It is determined by the difference in the distance between the pressure contact portion 45 and the convex portion 60.

The convex portion 60 and the adjusting portion 50 will be described by returning to FIGS. 3 and 4. As shown in FIGS. 3 and 4, the convex portion 60 is formed in the second wall portion 42 so as to project from the surface facing the second inner peripheral surface 24. The convex portion 60 has a rectangular parallelepiped shape, and the plan view of the first direction DR1 and the plan view of the third direction DR3 are substantially rectangular. Further, the convex portion 60 is integrally formed with the terminal connecting portion 40, and is made of a conductive metal member.

The convex portion 60 may be formed separately from the terminal connecting portion 40. For example, the convex portion 60 may be a metal plate-shaped member and may be fixed to the terminal connecting portion 40 by welding or the like.

The convex portion 60 is formed in a predetermined region of the second wall portion 42 in the first direction DR1 with the size of the first direction DR1 being approximately half the size of the first direction DR1 of the second wall portion 42. Has been done. Specifically, the convex portion 60 is provided at a position where one end of the first direction DR1 overlaps the second slope portion 47 in the first direction DR1 but does not overlap with the third slope portion 48. Further, in the convex portion 60, the other end of the first direction DR1 is separated from the other end of the first direction DR1 of the second wall portion 42 by a predetermined distance, and the first direction DR1 is the first. It is formed at a position overlapping the slope portion 46.

Further, in the convex portion 60, the size of the second direction DR2 is approximately half the size of the second direction DR2 of the portion forming the second inner peripheral surface 24 of the terminal insertion portion 20.

Further, in the convex portion 60, the size of the third direction DR3 is approximately 1/3 of the size of the third direction DR3 of the second wall portion 42, and the size of the second wall portion 42 is predetermined in the third direction DR3. It is formed in the area of. Specifically, the convex portion 60 is arranged substantially in the center of the second wall portion 42 in the third direction DR3 of the second wall portion 42.

As shown in FIGS. 3 and 4, the adjusting portion 50 is provided at a portion of the second inner peripheral surface 24 facing the convex portion 60. The adjusting unit 50 is a distance adjusting unit that adjusts the distance between the pressure contact portion 45 and the convex portion 60 when the power feeding terminal 91 is inserted into the terminal insertion hole 22. In the adjusting unit 50, the sizes of the first direction DR1, the second direction DR2, and the third direction DR3 are the first direction DR1, the second direction DR2, and the third direction DR3 of the convex portion 60, respectively. It is formed larger than each size of. The adjusting unit 50 is a portion with a dot pattern hatched in FIGS. 3 and 4.

The adjusting portion 50 formed in this way is inserted into the feeding terminal 91 by adjusting the position of the second direction DR2 of the convex portion 60 before the feeding terminal 91 is inserted into the terminal insertion hole 22. The distance between the front pressure welding portion 45 and the convex portion 60 is adjusted. Then, the adjusting portion 50 is the distance between the pressure contact portion 45 and the convex portion 60 before the power supply terminal 91 is inserted into the terminal insertion hole 22, and the pressure contact portion after the power supply terminal 91 is inserted into the terminal insertion hole 22. The difference in distance between the 45 and the convex portion 60 is adjusted.

Further, the adjusting unit 50 adjusts the displacement amount of the pressure contact portion 45 when the power feeding terminal 91 is inserted into the terminal insertion hole 22 by adjusting the difference in the distance. That is, the adjusting unit 50 adjusts the elastic force that the terminal connecting unit 40 pushes the power feeding terminal 91.

In the present embodiment, the adjusting unit 50 has a flat surface portion 52 formed in a plane with respect to the second inner peripheral surface 24 as shown in FIGS. 7 and 8, and a flat surface portion 52 as shown in FIGS. 9 and 10. It is formed by any of the recesses 51 formed by being recessed with respect to the second inner peripheral surface 24.

Explaining the case where the adjusting portion 50 is the flat surface portion 52, as shown in FIGS. 7 and 8, the flat surface portion 52 has a portion facing the convex portion 60 on substantially the same plane as the second inner peripheral surface 24. It is formed to be located. Further, the flat surface portion 52 is integrally formed with the terminal insertion portion 20, and is made of a resin member. The flat surface portion 52 may be formed separately from the terminal insertion portion 20. For example, the recess 51 may be a plate-shaped resin member and may be fixed to the second inner peripheral surface 24 which is partially recessed and formed.

In the flat surface portion 52 formed in this way, when the terminal connecting portion 40 is provided in the terminal insertion portion 20, the convex portion 60 comes into contact with the flat surface portion 52, so that the second wall portion 42 is brought into contact with the first wall portion 41. Can be approached to. As a result, as shown in FIG. 7, the terminal connection portion 40 has a power supply terminal 91 in the terminal insertion hole 22 as compared with the case where the adjustment portion 50 is formed by the recess 51 due to the deformation of the pressure contact portion 45. The distance between the pressure contact portion 45 and the convex portion 60 before being inserted can be reduced.

That is, the flat surface portion 52 can increase the displacement amount of the pressure contact portion 45 before the power feeding terminal 91 is inserted into the terminal insertion hole 22 as compared with the case where the adjusting portion 50 is formed by the recess 51.

Therefore, when the power feeding terminal 91 is inserted between the pressure welding portion 45 and the first wall portion 41 in a state where the displacement amount is large, the pressure welding when the power feeding terminal 91 is inserted into the terminal insertion hole 22. The displacement amount of the portion 45 is larger than that when the adjusting portion 50 is formed by the recess 51. Therefore, in the cover device 10, even if the size of the second direction DR2 of the power supply terminal 91 inserted into the terminal insertion hole 22 is the same, the terminal connection portion 40 pushes the power supply terminal 91 inserted into the terminal insertion hole 22. The elastic force can be increased as compared with the case where the adjusting portion 50 is formed by the recess 51.

Next, a case where the adjusting portion 50 is the recess 51 will be described. As shown in FIGS. 9 and 10, the recess 51 has a rectangular parallelepiped shape and is a plan view of the first direction DR1 and a plane of the third direction DR3. The view is substantially rectangular.

As shown in FIG. 9, the recess 51 is formed from the other end of the first direction DR1 on the second inner peripheral surface 24 toward one side. Further, the recess 51 is provided at a position where one end of the first direction DR1 is farther from the terminal insertion port 21 than the one end of the first direction DR1 of the convex portion 60.

As shown in FIG. 10, the concave portion 51 has a size of the second direction DR2 slightly larger than the size of the convex portion 60 in the second direction DR2. Further, the size of the third direction DR3 of the concave portion 51 is slightly larger than the size of the third direction DR3 of the convex portion 60. Further, the recess 51 is arranged substantially in the center of the second inner peripheral surface 24 in the third direction DR3. The concave portion 51 accommodates the convex portion 60 inside the concave portion 51 when the terminal connecting portion 40 is provided in the terminal insertion portion 20.

The recess 51 formed in this way includes the pressure contact portion 45 and the convex portion 60 before the power feeding terminal 91 is inserted into the terminal insertion hole 22, as compared with the case where the adjustment portion 50 is formed by the flat portion 52. Can increase the distance. In other words, the recess 51 is the distance between the pressure contact portion 45 and the convex portion 60 before the power supply terminal 91 is inserted into the terminal insertion hole 22, and the convex portion 60 is not provided on the second wall portion 42. The distance can be the same as the distance between the pressure contact portion 45 and the second wall portion 42.

Therefore, the cover device 10 can reduce the displacement amount of the pressure welding portion 45 when the power feeding terminal 91 is inserted into the terminal insertion hole 22 as compared with the case where the adjusting portion 50 is formed by the flat surface portion 52. Further, the cover device 10 determines the amount of displacement of the pressure contact portion 45 when the power supply terminal 91 is inserted into the terminal insertion hole 22, and the displacement of the pressure contact portion 45 when the convex portion 60 is not provided on the second wall portion 42. Can be the same amount as the amount.

Therefore, if the size of the second direction DR2 of the power supply terminal 91 inserted into the terminal insertion hole 22 is the same, the cover device 10 applies a force that the terminal connection portion 40 pushes the inserted power supply terminal 91. The adjustment portion 50 can be made smaller than the case where the adjustment portion 50 is formed by the recess 51. In other words, if the size of the second direction DR2 of the power supply terminal 91 inserted into the terminal insertion hole 22 is the same, the terminal connection unit 40 pushes the inserted power supply terminal 91. The force can be the same as the force pushed by the terminal connecting portion 40 when the convex portion 60 is not provided on the second wall portion 42.

Specifically, the difference in elastic force of the terminal connecting portion 40 between the case where the adjusting portion 50 is formed by the flat surface portion 52 and the case where the adjusting portion 50 is formed by the concave portion 51 will be described with reference to FIG. FIG. 11 shows the displacement amount of the pressure contact portion 45 and the elastic force of the terminal connection portion 40 that are displaced when the second power feeding terminal is inserted into the terminal insertion hole 22 when the adjustment portion 50 is the flat surface portion 52. .. Further, FIG. 11 shows the displacement amount of the pressure contact portion 45 and the elastic force of the terminal connection portion 40 that are displaced when the first power feeding terminal is inserted into the terminal insertion hole 22 when the adjustment portion 50 is the recess 51. Shown.

The displacement amount A in FIG. 11 indicates the displacement amount of the pressure welding portion 45 before the first power feeding terminal is inserted into the terminal insertion hole 22 when the adjusting portion 50 is the recess 51. The displacement amount D in FIG. 11 indicates the displacement amount of the pressure welding portion 45 before the second power feeding terminal is inserted into the terminal insertion hole 22 when the adjusting portion 50 is the flat surface portion 52. The displacement amount C in FIG. 11 is the displacement amount of the pressure welding portion 45 after the first power feeding terminal is inserted into the terminal insertion hole 22 when the adjusting portion 50 is the recess 51, and the adjusting portion 50 is the flat surface portion 52. In this case, the displacement amount of the pressure contact portion 45 after the second power feeding terminal is inserted into the terminal insertion hole 22 is shown. The displacement amount A shown in FIG. 11 is the same as the displacement amount A shown in FIG. Further, the displacement amount C shown in FIG. 11 is the same as the displacement amount C shown in FIG.

When the adjusting portion 50 is a flat portion 52, as shown in FIG. 11, the displacement amount of the pressure contact portion 45 before the second power feeding terminal is inserted into the terminal insertion hole 22 is such that the adjusting portion 50 has a recess 51. Compared with the case, the size of the convex portion 60 in the second direction DR2 is increased. Therefore, the flat surface portion 52 can increase the elastic force of the terminal connecting portion 40 before the second power feeding terminal is inserted into the terminal insertion hole 22 as compared with the case where the adjusting portion 50 is the recess 51.

Further, when the second power feeding terminal is inserted between the pressure welding portion 45 and the first wall portion 41 in a state where the displacement amount is large, after the second feeding terminal is inserted into the terminal insertion hole 22. The displacement amount of the pressure contact portion 45 is further increased by the distance L2. Therefore, the cover device 10 compares the elastic force of the terminal connecting portion 40 when the power feeding terminal 91 to be inserted is the second feeding terminal with the case where the adjusting portion 50 is the recess 51, and connects the terminals. The elastic force of the portion 40 can be increased. Further, the cover device 10 can adjust the size of the second direction DR2 of the convex portion 60 so that the force for pushing the inserted power feeding terminal 91 by the terminal connecting portion 40 can be made larger than the required load.
Therefore, even if the size of the second direction DR2 of the power feeding terminal 91 is such that it is difficult to secure the displacement amount of the pressure contact portion 45, the cover device 10 keeps the power feeding terminal 91 and the terminal connecting portion 40 conductive. The terminal connection portion 40 can push the power supply terminal 91 with a force for securing.

Further, when the adjusting portion 50 is the concave portion 51, as shown in FIG. 11, the displacement amount of the pressure contact portion 45 before the first power feeding terminal is inserted into the terminal insertion hole 22 is such that the convex portion 60 is in the concave portion 51. By being accommodated, the amount is the same as when the convex portion 60 is not provided on the second wall portion 42. Therefore, the concave portion 51 can reduce the elastic force of the terminal connecting portion 40 before the first power feeding terminal is inserted into the terminal insertion hole 22 as compared with the case where the adjusting portion 50 is the flat surface portion 52.

Further, a first power feeding terminal is provided between the pressure contact portion 45 and the first wall portion 41 in a state where the displacement amount of the pressure contact portion 45 is the same as when the convex portion 60 is not provided on the second wall portion 42. When inserted, the displacement amount of the pressure contact portion 45 becomes the distance L1. In this case, if the size of the second direction DR2 of the power feeding terminal 91 inserted into the terminal insertion hole 22 is the same, the cover device 10 is a terminal as compared with the case where the adjusting portion 50 is the flat portion 52. The force of the terminal connection portion 40 after the first power supply terminal is inserted into the insertion hole 22 can be reduced.

Therefore, when the size of the second direction DR2 of the power feeding terminal 91 is large enough to secure the displacement amount of the pressure contact portion 45, the cover device 10 accommodates the convex portion 60 in the concave portion 51 for power feeding. It is possible to avoid applying an excessive load to the terminal 91 and the terminal connection portion 40.

Further, since the second wall portion 42 and the convex portion 60 are integrally formed, the structure can be simplified as compared with the case where the second wall portion 42 and the convex portion 60 are formed separately.

Therefore, the convex portion 60 is provided at a position closer to the terminal insertion port 21 than the portion where the pressure contact portion 45 abuts on the first wall portion 41 in the first direction DR1.

It can be provided at a position close to the other end of the 42 in the first direction DR1. That is, when the adjusting portion 50 is the flat surface portion 52, the position where the flat surface portion 52 and the convex portion 60 come into contact with each other may be provided at a position close to the other end of the second wall portion 42 in the first direction DR1. it can.
