Japanese Patent No. 5579184

The wall-mounted device described in Patent Document 1 is provided with a protective element so that the connector cannot be connected to the plug-in connection portion until the assembly of the wall-mounted device to the opening provided in the wall is completed. By providing this protective element, assembly can be guaranteed, but the large size of the protective element interferes with the connector connection work. Further, since the connector connection work cannot be performed until the assembly of the wall mounting device to the opening provided in the wall is completed, there is a work restriction on the connector connection timing.

In view of the above points, it is an object of the present invention to provide a wall mounting device having a structure capable of eliminating a protective element and improving workability while enabling assembly guarantee.

In order to achieve the above object, the invention according to claim 1 is a wall mounting device assembled to an opening (101) provided in the wall (100), and is fixedly arranged with respect to the wall. A plate-shaped base plate (10) on the fixed side and having a through hole (11) formed therein, and a holding element (21) having a support wing (23) fitted into the through hole are provided, and the axis of the holding element is centered. As the shaft (22), it has a disk-shaped wing rotor (20) on the movable side that can rotate relative to the base plate, and a connector (60) from which the terminal (50) is exposed.

Then, the support wing is fitted into the through hole so that one side of the wing rotor is directed to one side of the base plate, the base plate and the wing rotor are integrated, and the connector is on the opposite side of the wing rotor from the base plate. The movable side contact (26) is provided on one side of the base plate side of the wing rotor, and the fixed side contact is provided on one side of the wing rotor side of the base plate. (15) is provided. Of the movable side contact and fixed side contact, the contact provided on either the fixed side or the movable side where the connector is integrated is the terminal connection contact to which the terminal is connected, and is not assembled to the opening. Before rotating the wing rotor with respect to the base plate, the movable side contact and the fixed side contact are in a non-conducting state, and after assembling to the opening, after rotating the wing rotor with respect to the base plate. The movable side contact and the fixed side contact are in a conductive state, and the non-conducting state and the conductive state can be confirmed through the terminal.

In this way, the base plate is provided with the fixed side contact, and the wing rotor is provided with the movable side contact. In the state before assembling the wall mounting device to the opening of the wall, the fixed side contact and the movable side contact are prevented from conducting, and after assembling, the fixed side contact and the movable side contact are made conductive. .. For this reason, by simply checking the continuity between the fixed side contact and the movable side contact through the terminal, an assembly guarantee is provided to confirm whether or not the wall mounting device is properly assembled to the opening provided in the wall. It can be carried out. That is, when the assembly is not completed, the fixed side contact and the movable side contact are not conducting, and the continuity cannot be confirmed, so that the assembly incomplete can be detected.

Therefore, while ensuring assembly, it is possible to eliminate the protective element that covers the connector, eliminate restrictions on connection timing, and improve workability when assembling the pressure sensor device. It becomes.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each of the following embodiments, the parts that are the same or equal to each other will be described with the same reference numerals.

(First Embodiment)
The wall-mounted device according to the first embodiment of the present invention will be described. Here, as the wall mounting device, a pressure sensor device assembled to an opening provided in the wall will be described as an example, but a wall mounting device other than the pressure sensor device may be used.

The pressure sensor device shown in FIGS. 1 to 6 is used to detect the operation of a side airbag for a vehicle. For example, the pressure sensor device is attached to an inner panel attached to the inside of the side door of the vehicle, and an electronic control device for an airbag (hereinafter referred to as an airbag ECU) outputs a detection signal according to the pressure in the door internal space to be detected. ). As a result, the airbag ECU detects the pressure change in the internal space of the door that occurs when the vehicle collides with the door based on the detection signal from the pressure sensor device, and activates the side airbag to protect the occupants. ..

Specifically, the pressure sensor device is configured to include a base plate 10, a wing rotor 20, a pressure sensor IC 30, a printed circuit board 40, a terminal 50, a connector 60, and the like.

The base plate 10 is composed of a disk-shaped member. As shown in FIG. 3, a through hole 11 is formed at an inner position of the base plate 10, and a holding element 21 to be described later, which is formed in the wing rotor 20, can be fitted into the through hole 11. In the case of the present embodiment, the through hole 11 is composed of a substantially rectangular opening having one direction in the plane direction of the base plate 10 as the longitudinal direction and the vertical direction thereof being the lateral direction. Hereinafter, as shown in FIG. 3, the longitudinal direction of the through hole 11 in the plane direction of the base plate 10 is referred to as the X direction, the lateral direction is referred to as the Y direction, and the normal direction with respect to the XY plane is referred to as the Z direction.

The through hole 11 of the base plate 10 has a central hole 11a whose opening size is partially increased by being opened in a circular shape at the central portion. The central hole 11a is an opening for accommodating the central shaft 22 of the holding element 21 in the wing rotor 20.

Further, when the side of the base plate 10 where the portion other than the holding element 21 of the wing rotor 20 is arranged is the back surface and the opposite side is the front surface, the sealing portion 14 arranged so as to surround the through hole 11 is provided on the front surface side. It is prepared. The sealing portion 14 is provided to seal the gap between the wall and the base plate 10 when the wall mounting device is assembled to the opening of the wall.

Further, the outer diameter of the base plate 10 is one size larger than the outer diameter of the wing rotor 20. A peripheral wall 16 protruding toward the wing rotor 20 is formed on the outer edge of the back surface of the base plate 10, and the wing rotor 20 is inserted into the peripheral wall 16 as shown in FIGS. 1 and 2. It has become. As shown in FIGS. 1 and 3, an engaging claw 17 is formed on a part of the peripheral wall 16, and when the base plate 10 and the wing rotor 20 are assembled, the engaging claw 17 causes the base plate 10 and the wing rotor 20. And are integrated. Even after the base plate 10 and the wing rotor 20 are integrated, the relative rotation between the base plate 10 and the wing rotor 20 is possible.

Further, as shown in FIGS. 2 and 4A, the back surface of the base plate 10 is provided with a fixed side contact 15. The fixed side contact 15 is brought into contact with the movable side contact 26 provided on the wing rotor 20 side, which will be described later. As will be described later, the movable side contact 26 is a contact divided into two, but the fixed side contact 15 is composed of one contact having a size that allows contact with both of the two movable side contacts 26. Has been done. The fixed-side contact 15 is formed at a position where the fixed-side contact 15 and at least one of the two movable-side contacts 26 do not yet come into contact with each other when the holding element 21 is fitted into the through hole 11. Then, when the holding element 21 is rotated around the central axis of the base plate 10 as described later, the fixed side contact 15 is formed at a position where both of the two movable side contacts 26 come into contact with each other.

The wing rotor 20 corresponds to a support element, is made of an insulating material such as resin, and integrally holds the pressure sensor IC 30, the printed circuit board 40, the terminal 50, and the connector 60. The wing rotor 20 has a disk shape, and has a structure in which one side is a front surface and the opposite side is a back surface, and a holding element 21 is provided on the front surface side.

The holding element 21 has a central shaft 22 and a support wing 23 that is enlarged in the radial direction from the central shaft 22 and in the X direction in FIG. The central shaft 22 has a substantially cylindrical shape, and is arranged in the central hole 11a of the base plate 10 described above.

A pressure introduction hole 24 penetrating the front and back surfaces of the wing rotor 20 is formed in the support wing 23 and the central shaft 22. Through the pressure introduction hole 24, the pressure in the door internal space can be introduced from the front surface side to the back surface side of the wing rotor 20.

Further, the back surface side of the wing rotor 20 has a shape that matches the shape of the connector 60 and the like. The pressure sensor IC 30, the printed circuit board 40, and the terminal 50 are fixed to the wing rotor 20 so as to be housed in the connector 60 on the back surface side. Two support portions 25 extending in the Z direction are arranged on the back surface side of the wing rotor 20, and the connector 60 is integrated so as to be arranged between the two support portions 25. Therefore, the wing rotor 20 and the connector 60 and the like can be rotated integrally.

Further, as shown in FIG. 4B, two movable side contacts 26 are exposed on the surface side of the wing rotor 20. The two movable side contacts 26 may be formed at different positions and at positions where the holding element 21 comes into contact with the fixed side contact 15 when the holding element 21 is rotated around the central axis of the base plate 10, as described later. In the form, they are arranged side by side in the circumferential direction. As shown in FIG. 2, the movable side contact 26 is configured such that a part of the wiring portion 27 provided so as to penetrate from the front surface side to the back surface side of the wing rotor 20 is exposed on the front surface side of the wing rotor 20. Has been done. The wiring portion 27 is integrated with the wing rotor 20, for example, by integral molding or the like. The wiring portion 27 is electrically connected to an inspection pattern included in a wiring pattern (not shown) formed on the printed circuit board 40.

Further, as shown in FIG. 1, a protrusion 28 forming a part of the rotation lock portion is formed on the outer peripheral surface of the wing rotor 20. At the time of assembly, the stop portion 18 formed on the inner peripheral surface of the peripheral wall 16 of the base plate 10 gets over the protrusion 28 and engages with the base plate 10 to lock the relative rotation between the base plate 10 and the wing rotor 20. That is, the lock portion is composed of the protrusion 28 and the stop portion 18. The protrusion 28 does not engage with the stop 18 when the holding element 21 is fitted into the through hole 11 and the wing rotor 20 has not yet been rotated with respect to the base plate 10. Then, when the wing rotor 20 is rotated with respect to the base plate 10, the stop portion 18 gets over the protrusion 28, and when the assembly is completed, or immediately before that, the protrusion 28 engages with the stop portion 18.

As described above, when the assembly is completed, the fixed side contact 15 and the movable side contact 26 become conductive, but the conduction is not completed before the protrusion 28 and the stop portion 18 engage with each other. Then, it is preferable. For example, it is assumed that the state in which the holding element 21 is only fitted in the through hole 11 and is not rotated is set to 0 °, and the angle at which the wing rotor 20 is rotated by a predetermined angle is the angle at which the assembly is completed. In that case, the stop portion 18 gets over the protrusion 28 and engages with the stop portion 18 about 1 to 2 ° before the predetermined angle at which the assembly is completed. More preferably, it is preferable that the conduction between the fixed side contact 15 and the movable side contact 26 starts when more than half of the stop portion 18 gets over the protrusion 28 in the rotation direction.

The pressure sensor IC 30 is formed with a pressure sensor element formed on a semiconductor chip, and is integrally provided with a control unit such as a signal processing unit as needed. A detection signal corresponding to the pressure in the door internal space is output from the pressure sensor IC 30. Then, the pressure sensor IC 30 is mounted on the printed circuit board 40 and is electrically connected to the terminal 50 through the printed circuit board 40, so that the detection signal of the pressure sensor IC 30 is transmitted to the airbag ECU provided externally through the terminal 50. ..

The printed circuit board 40 is for mounting the pressure sensor IC 30 and electrically connecting to the terminal 50, and although not shown, a wiring pattern or the like constituting an electric circuit is formed. Each part of the pressure sensor IC 30 is electrically connected to the printed circuit board 40 by, for example, wire bonding. As described above, a control unit such as a signal processing unit can be formed on the pressure sensor IC 30, but the control unit can also be mounted on the printed circuit board 40.

Further, an inspection pattern is formed on the printed circuit board 40. The inspection pattern is a pattern in which the two movable side contacts 26 and the fixed side contact 15 are non-conducting before being electrically connected, and are conducting when they are electrically connected. Here, the inspection pattern is incorporated in the wiring pattern through which the detection signal of the pressure sensor IC 30 is transmitted, and the pressure sensor IC 30 does not operate unless the inspection pattern is conductive, but it can be provided separately from the wiring pattern.

The terminal 50 is connected to a desired position of a wiring pattern or an inspection pattern formed on the printed circuit board 40, and enables electrical connection with the outside of the pressure sensor device. The terminal 50 includes a power supply, a ground (GND), a signal output, and the like. When the inspection pattern is incorporated as a part of the wiring pattern, the terminal 50 can be used for power supply, grounding, signal output, or the like for inspection. Further, as described above, when the inspection pattern is provided separately from the wiring pattern to which the detection signal of the pressure sensor IC 30 is transmitted, an inspection terminal connected to the inspection pattern is also provided as the terminal 50.

The connector 60 is a hollow member constituting a casing that houses the pressure sensor IC 30, the printed circuit board 40, and the terminal 50, and is made of, for example, a hard insulating resin. Further, the connector 60 is connected to an external connector (not shown) to enable electrical connection between the pressure sensor IC 30 and the outside through the terminal 50.

Specifically, the connector 60 is configured to have a substantially rectangular parallelepiped housing portion 61 and a long cylindrical connector case 62. The accommodating portion 61 has a hollow shape, and one surface on the upper side, that is, the wing rotor 20 side is open. The pressure sensor IC 30 and the printed circuit board 40 are accommodated in this opened portion. Further, the tip of the wiring portion 27 provided in the wing rotor 20 on the opposite side to the movable side contact 26 is made to protrude into the accommodating portion 61, and is electrically connected to the printed circuit board 40. Further, the pressure introduction hole 24 is communicated with the accommodating portion 61 so that the pressure in the door internal space is guided to the accommodating portion 61 side.

Further, a partition wall 61a to which the printed circuit board 40 is brought into close contact is formed in the accommodating portion 61. The inside of the accommodating portion 61 is divided into two spaces 61b and 61c by the partition wall 61a and the printed circuit board 40, and the pressure sensor IC 30 is arranged in the space 61b on the wing rotor 20 side on one side thereof. When the pressure in the door internal space is guided to the space 61b side through the pressure introduction hole 24, the space 61b and the space 61c are partitioned in an airtight state, so that the pressure in the door internal space is on the space 61c side. It is applied to the pressure sensor IC 30 on the space 61b side without coming off.

The space 61b may be filled with the atmosphere, but may be filled with a filler. In that case, the pressure in the door internal space can be applied to the pressure sensor IC 30 via the filler.

The terminal 50 described above is provided so that one end side protrudes from the space 61c side into the space 61b, is inserted into a through hole (not shown) formed in the printed circuit board 40, and is soldered so as to embed the through hole. This is connected to the printed circuit board 40. Further, since the intermediate position of the terminal 50 is bent in the X direction, the other end of the terminal 50 is extended to the connector case 62 side.

The connector case 62 is provided at one end of the connector 60, and the other end of the terminal 50 is exposed from the connector case 62. By connecting an external connector to the connector case 62, the pressure sensor IC 30 can be electrically connected to the outside via the terminal 50.

Assembling to the opening formed in the wall of the pressure sensor device configured as described above will be described.

First, the base plate 10 is fitted into the wing rotor 20 in which the pressure sensor IC 30, the printed circuit board 40, the terminal 50, and the connector 60 are integrated. Specifically, as shown in FIG. 3, the holding element 21 and the through hole 11 of the base plate 10 are aligned with each other, and the holding element 21 is inserted into the through hole 11. Then, when the wing rotor 20 is fitted into the peripheral wall 16 so as to push the engaging claw 17 away, the engaging claw 17 returns to its original position due to the elastic reaction force and is caught on the end face of the wing rotor 20 to catch the wing rotor 20. 20 and the base plate 10 are integrated.

At this time, as shown in FIGS. 4A and 4B, the fixed side contact 15 provided on the base plate 10 and the movable side contact 26 provided on the wing rotor 20 are located at different locations. It is in a state where it is not electrically connected.

In this state, after fitting the holding element 21 into the opening 101 formed in the wall 100 as shown in FIG. 5, the holding element 21 is rotated. For example, the holding element 21 and the base plate 10 are grasped from both sides of the wall 100, and the holding element 21 is rotated with respect to the base plate 10 as shown by an arrow in FIG. 6A. Further, since the sealing portion 14 comes into contact with the wall surface to prevent the base plate 10 from rotating, the holding element 21 can be rotated with respect to the base plate 10 simply by rotating the holding element 21. As a result, the wing rotor 20, the connector 60, and the like can be rotated together with the holding element 21 without moving the base plate 10.

Therefore, as shown in FIG. 5, the wall 100 is sandwiched between the base plate 10 and the holding element 21, so that the pressure sensor device is assembled to the opening 101 provided in the wall 100.

At this time, as shown in FIGS. 6A and 6B, the movable side contact 26 provided in the wing rotor 20 moves while the position of the fixed side contact 15 provided in the base plate 10 does not change. Both of the movable side contacts 26 are brought into contact with the fixed side contacts 15. Therefore, the two movable side contacts 26 and the fixed side contacts 15 are electrically connected. Therefore, by confirming the continuity through the terminal 50, it is possible to guarantee the assembly of the pressure sensor device to the wall 100.

As described above, in the pressure sensor device of the present embodiment, the base plate 10 is provided with the fixed side contact 15, and the wing rotor 20 is provided with the movable side contact 26. Then, in the state before assembling the pressure sensor device to the opening 101 of the wall 100, the fixed side contact 15 and the movable side contact 26 are kept from conducting, and after assembling, the fixed side contact 15 and the movable side contact 26 are connected. I try to make it conductive. Therefore, it is confirmed whether or not the pressure sensor device is properly assembled to the opening 101 provided in the wall 100 only by confirming the continuity between the fixed side contact 15 and the movable side contact 26 through the terminal 50. It is possible to guarantee the assembly. That is, when the assembly is not completed, the fixed side contact 15 and the movable side contact 26 are not conducting, and the continuity cannot be confirmed, so that the assembly incomplete can be detected.

Therefore, it is possible to abolish the protective element that covers the connector 60 while enabling the assembly guarantee, and it is possible to eliminate the restrictions on the connection timing and improve the workability at the time of assembling the pressure sensor device. It will be possible.

(Other embodiments)
Although the present disclosure has been described in accordance with the above-described embodiment, the present disclosure is not limited to the embodiment, and includes various modifications and modifications within a uniform range. In addition, various combinations and forms, as well as other combinations and forms that include only one element, more, or less, are within the scope and scope of the present disclosure.

(1) For example, in the first embodiment, an example of the configuration of the fixed side contact 15 and the movable side contact 26 is given, but the present invention is not limited to this. That is, one surface of the base plate 10 and one surface of the wing rotor 20 are integrated so as to face each other, but other than that, if the structure is such that contacts are provided on each surface of the base plate 10 and one surface of the wing rotor 20. The structure may be. More specifically, after the holding element 21 is fitted in the through hole 11, both contacts become non-conducting in the state before assembling before rotating the holding element 21, and the set is after rotating the holding element 21. Any structure may be used as long as it is conductive after being attached.

As an example, the formation positions of the fixed side contact 15 and the movable side contact 26 are formed at any position as long as they do not conduct in the state before assembly but conduct in the state after assembly. It may have been done. However, in order to prevent the movable side contact 26 from conducting with the fixed side contact 15 during rotation before the assembly is completed, the fixed side contact 15 and the movable side contact 15 are at a position where the stop portion 18 exceeds the protrusion 28 by more than half. It is preferable to make 26 conductive.

Here, an example in which the lock portion is composed of the stop portion 18 and the protrusion portion 28 is shown, but the present invention is not limited to these. For example, a hole for fitting the protrusion 28 is formed on the inner peripheral surface of the peripheral wall 16 of the base plate 10, and the protrusion 28 is fitted into the hole to lock the rotation of the base plate 10 and the wing rotor 20. The lock portion may be configured.

(2) Further, in order to alleviate the crossing of the set positions of the fixed side contact 15 and the movable side contact 26, these fixed side contact 15 and the movable side contact 26 are installed on the outer peripheral side of the base plate 10 and the wing rotor 20 as much as possible. preferable.

(3) Further, it is preferable that the fixed side contact 15 and the movable side contact 26 are arranged above the center of rotation so that water does not collect at the contact position. For example, the vicinity of the central axis 22 of the wing rotor 20 is recessed on the side away from the base plate 10, and the fixed side contact 15 and the movable side contact 26 are positioned closer to the base plate 10 than the recessed position. By doing so, it is possible to prevent water from accumulating at the contact position.

(4) Further, a waterproof seal can be set around the fixed side contact 15 in the base plate 10 or at least one around the movable side contact 26 in the wing rotor 20 so as to surround the contact. Even in this way, water is formed at the contact position.

(5) Further, in the first embodiment, the pressure sensor IC 30, the printed circuit board 40, the terminal 50 and the connector 60 are integrated with the rotating side, that is, the wing rotor 20. On the other hand, the structure may be such that these are integrated with the fixed side, that is, the base plate 10. In that case, since the connector 60 and the like are fixed, the structure is provided with two fixed-side contacts 15 and one movable-side contact 26. Then, before assembly, that is, before the rotation of the wing rotor 20, the movable side contact 26 is in a state where it does not contact at least one of the fixed side contacts 15, and after assembly, the movable side contact 26 contacts both of the fixed side contacts 15. It is preferable to make the structure conductive.

In other words, the base plate 10 is the fixed side that is fixedly arranged with respect to the wall 100, and the wing rotor 20 is the movable side that is rotated with respect to the fixed side, but the connector 60 is either the fixed side or the movable side. Then, the number of the fixed side contact 15 and the movable side contact 26 is determined. That is, if the connector 60 is integrated on the fixed side, the fixed side contact 15 may be two, and if the connector 60 is integrated on the movable side, the movable side contact 26 may be two. Of the fixed side contact 15 and the movable side contact 26, the contact provided on either the fixed side or the movable side where the connector 60 is integrated is a terminal connection contact to which the terminal 50 is connected.
