(Problems to be solved by the invention)
The electric circuit device of the vehicle door lock device is configured according to the specifications of the vehicle. That is, for example, a courtesy switch specification including only a courtesy switch, a position switch specification including only a position switch, and a full specification electric circuit device including both switches are respectively configured. That is, the electric circuit device of the courtesy switch specification includes a courtesy switch, one set (two) terminals, and a connector. Further, the electric circuit device of the position switch specification includes a position switch, a set (two) terminals, and a connector. The full-specification electric circuit device includes a courtesy switch, a position switch, two sets (four) of terminals, and a connector.

  Here, in order to make the components of the electric circuit device as common as possible, consider a case where the terminals and connectors of the full specification electric circuit device are used in all vehicles. If the courtesy switch is installed in the terminal for the courtesy switch and the position switch is not installed in the terminal for the position switch, the electric circuit of the courtesy switch specification will be used. It is also thought that it can function as a device. However, in this case, the terminal for the position switch is not fixed to the housing. Therefore, there is a possibility that the position of the terminal for the position switch is shifted during traveling and the terminal for the courtesy switch is short-circuited. In this case, there is a possibility that the open / closed state of the vehicle door is erroneously detected. If a position switch is mounted on the terminal for the position switch and a courtesy switch is not mounted on the terminal for the courtesy switch, the terminal can function as an electric circuit device of a position switch specification. However, in this case, the terminal for the courtesy switch is not fixed to the housing. Therefore, there is a possibility that the position of the courtesy switch terminal is displaced during traveling and the terminal is short-circuited to the position switch terminal. In this case, the locked / unlocked state of the dual-purpose door may be erroneously detected.

  Therefore, as described above, a dedicated terminal is manufactured for each specification by using a different mold for each specification. Therefore, the initial investment cost of the vehicle door lock device was high. Further, the productivity of the vehicle door lock device (in particular, the assemblability of the electric circuit device) was low.

  Hereinafter, a vehicle door lock device 1 to which an electric circuit device 40 according to an embodiment of the present invention is applied will be described. Although the present embodiment is an example in which the present invention is applied to a door lock device for a right door of a vehicle, the present invention is also applicable to a door lock device for another door.

  As shown in FIG. 1, the vehicle door lock device 1 is disposed between a door outer panel OP (outside panel) and a door inner panel IP (inside panel) of the vehicle door DR.

  As shown in FIG. 2, the vehicle door lock device 1 includes a housing 10, a latch mechanism 20, a lock mechanism 30, and an electric circuit device 40 (an electric circuit device 40A, an electric circuit device 40B, and an electric circuit device 40C. Two devices). In FIG. 2, components of the latch mechanism 20 are omitted. FIG. 3 is referred to for a specific configuration of the latch mechanism 20.

  The housing 10 is a box-shaped member that houses the latch mechanism 20, the lock mechanism 30, and the electric circuit device 40. The housing 10 is made of a synthetic resin.

  The housing 10 includes a rear wall portion 111 perpendicular to the vehicle front-rear direction and a side wall portion 112 perpendicular to the vehicle width direction. The left end of the rear wall 111 and the rear end of the side wall 112 are connected.

  The latch mechanism 20 holds the vehicle door DR in a closed state by engaging with a striker attached to the periphery of the entrance of the vehicle body. As shown in FIGS. 3 and 4, the latch mechanism 20 includes a latch 21, a pawl 22, a courtesy switch lever 23, and the like, which are the same as those of a known vehicle door lock device.

  The latch 21 is a substantially disc-shaped member rotatably supported around a shaft member provided on the rear wall portion 111. The latch 21 has a cutout portion 211 extending inward from an outer peripheral surface thereof. When the turning position of the latch 21 is at the unlatching position, the vehicle door DR can be opened. When the vehicle door DR is closed from this state, the latch 21 receives the striker in the notch 211 and rotates in a predetermined direction (counterclockwise in FIG. 3). Then, the pawl 22 is engaged with the latch 21, and the vehicle door DR is held in a closed state. That is, the pawl 22 holds the turning position of the latch 21 at the latch position (a state where the vehicle door cannot be opened). The pawl 22 is connected to an inside door handle IH provided on the vehicle interior side surface of the vehicle door DR and an outside door handle OH provided on the vehicle exterior side surface of the vehicle door DR via a lift lever and an open link (not shown). 1). When the inside door handle IH or the outside door handle OH is pulled, the pawl 22 rotates via the open link and the lift lever, and the engagement with the latch 21 is released. Thereby, the rotation position of the latch 21 returns to the unlatched position.

  The courtesy switch lever 23 is rotatably supported around a shaft member provided on the side wall portion 112, as shown in FIGS. The courtesy switch lever 23 has a first arm 231 and a second arm 232. The first arm 231 extends from the center of rotation of the courtesy switch lever 23 toward the latch 21 (rearward), and a distal end portion thereof contacts an outer peripheral surface of the latch 21. The second arm 232 extends substantially upward from the center of rotation of the courtesy switch lever 23, and its tip is located near a courtesy switch 41 described later. The courtesy switch lever 23 rotates in conjunction with the rotation of the latch 21. When the latch 21 rotates from the latch position to the unlatched position, the courtesy switch lever 23 rotates counterclockwise in FIGS.

  The lock mechanism 30 switches between an unlocked state where the engagement between the latch mechanism 20 and the striker can be released and a locked state where the engagement between the latch mechanism 20 and the striker cannot be released. As shown in FIG. 4, the lock mechanism 30 includes an active lever 31, a position switch lever 32, and the like.

  The active lever 31 is rotatably supported around a shaft member provided on the side wall portion 112. The active lever 31 is connected to a locking / unlocking operator (for example, a door lock knob) and is also connected to an open link. When the locking / unlocking operator is set to the unlocked state, the rotation position of the active lever 31 is at a predetermined unlock position. In this state. The engagement between the open link and the lift lever is released, and the operations of the inside door handle IH and the outside door handle OH are transmitted to the pawl 22. On the other hand, when the locking / unlocking operation element is set to the locked state, the active lever 31 rotates in a predetermined direction, the open link is moved, and the engagement between the open link and the lift lever is released. Therefore, the operations of the inside door handle IH and the outside door handle OH are not transmitted to the pawl 22.

  The position switch lever 32 is pivotally supported by the side wall 112. The position switch lever 32 has a first arm 321 and a second arm 322. The first arm 321 extends from the rotation center of the position switch lever 32 to the active lever 31 side (downward), and a tip end thereof contacts an outer peripheral surface of the active lever 31. The second arm 322 extends upward from the center of rotation of the position switch lever 32, and has a distal end located near a position switch 42 described later. In conjunction with the rotation of the active lever 31, the position switch lever 32 rotates.

  For further specific configurations of the latch mechanism 20 and the lock mechanism 30, for example, reference is made to "latch unit" and "actuator unit" disclosed in JP-A-2017-95954.

  Next, the electric circuit device 40A will be described. The electric circuit device 40A includes a courtesy switch 41, a position switch 42, a terminal 43, and a connector housing 44, as shown in FIGS. As the courtesy switch 41 and the position switch 42, known micro switches are used. That is, the courtesy switch 41 includes a case 411 and an actuator 412 (see FIG. 7). Two electrical contacts are provided in case 411. Usually, the two electrical contacts are separated and in a non-conductive state. When the actuator 412 is pressed, the two electrical contacts come into contact, and the two electrical contacts become conductive. The position switch 42 includes a case 421 and an actuator 422 similar to the courtesy switch 41. The structure of the electric contacts of the position switch 42 is the same as that of the courtesy switch 41.

A mounting hole FH ₄₁₁ and a mounting hole FH ₄₂₁ are formed in the case 411 and the case 421, respectively. Further, a pin insertion hole PH ₄₁₁ and a pin insertion hole PH ₄₂₁ are formed in the case 411 and the case 421, respectively. The shape and size of the pin insertion hole PH ₄₁₁ are the same as the shape and size of the pin insertion hole PH ₄₂₁ . Note that the courtesy switch 41 and the position switch 42 correspond to the electric components of the present invention.

  The terminal 43 includes a terminal set 431 and a terminal set 432 corresponding to the courtesy switch 41 and the position switch 42, respectively. The terminal set 431 includes a terminal Ta and a terminal Tc, and the terminal set 432 includes a terminal Tb and a terminal Tc. That is, the terminal Tc is shared by the terminal set 431 and the terminal set 432. The terminals Ta, Tb, Tc are formed of an elongated metal plate. The terminals Ta, Tb, Tc are appropriately curved at their intermediate portions. Pins P are respectively formed at both ends of the terminals Ta, Tb, Tc in the extending direction. Also, a pin P is formed at an intermediate portion in the extending direction of the terminal Tc. These pins P extend perpendicularly to portions of each terminal other than the pins P.

The pins P on the tip end sides of the terminals Ta, Tc are inserted into the pin insertion holes PH ₄₁₁ , PH ₄₁₁ of the courtesy switch 41. The pin P on the tip end side of the terminal Tb and the pin P in the middle of the terminal Tb are inserted into the pin insertion holes PH ₄₂₁ , PH ₄₂₁ of the position switch 42. Further, the pins P on the base end side of the terminals Ta, Tb, Tc are housed in housing sections provided in the connector housing 44, respectively. Incidentally, the connector housing 44 is provided with a mounting hole _{FH 44.}

  Note that the terminal set 431 corresponds to the first conductive line of the present invention, and the terminal set 432 corresponds to the second conductive line of the present invention. The terminals Ta and Tc correspond to the first conductive plate of the present invention, and the terminals Tb and Tc correspond to the second conductive plate of the present invention. Further, the pin P corresponds to a terminal of the present invention.

The side wall portion 112, mounting holes _{FH 411, FH 421} of courtesy switch 41 and the position switch 42, and have the corresponding bosses BS are respectively provided in the mounting hole _{FH 44} of the connector housing 44, the hole these bosses BS are attached FH ₄₁₁ , FH ₄₂₁ , and FH ₄₄ are inserted and fitted respectively. As a result, the distal ends of the terminals Ta, Tb, and Tc and the intermediate portion of the terminal Tc are locked to the side wall 112. Further, a pin P described later is inserted into the pin insertion hole PH ₄₁₁ and the pin insertion hole PH ₄₂₁ , respectively, so that the pin P and the electrical contact of each switch are in contact, and the pin P and the electrical contact of each switch are in a conductive state. It has become.

  The electric circuit device 40 </ b> A configured as described above is manufactured as follows and assembled to the side wall portion 112. First, a switch material plate piece ST is formed by punching a base material made of a metal plate. The switch terminal plate ST is a member having a shape in which plate portions corresponding to the terminals Ta, Tb, and Tc are connected at an intermediate portion thereof (see FIG. 7).

  Next, of the switch terminal plate piece ST, the roots of the portions corresponding to the pins P of the terminals Ta, Tb, and Tc are bent so that the pins P are processed so as to extend perpendicularly to the other portions. . Next, the courtesy switch 41 is mounted on the pin P at the tip of the terminals Ta and Tc of the switch terminal plate ST (see FIG. 7). The position switch 42 is mounted on the pin P at the tip of the terminal Tb of the switch terminal plate ST and the pin P at the middle of the terminal Tc.

  Next, the connector housing 44 is assembled to the pins P at the base ends of the terminals Ta, Tb, and Tc of the switch terminal plate piece ST. Next, as shown in FIG. 8, the switch terminal plate ST on which the courtesy switch 41, the position switch 42, and the connector housing 44 are assembled is placed on the side wall 112, and the courtesy switch 41, the position switch 42 and the connector housing 44 are locked.

  Lastly, the connecting portions CP connecting the intermediate portions of the terminals Ta, Tb, Tc of the switch terminal plate piece ST are cut by the cutting tool. That is, the terminals Ta, Tb, and Tc are separated.

  A controller (ECU) is connected to the connector housing 44 via a cable (wire harness) not shown. Thereby, the terminals Ta and Tb are connected to the input ports of the control device, respectively. Further, the terminal Tc is connected to a reference potential terminal of the control device (for example, a positive electrode or a negative electrode of a power supply circuit).

  For example, when the latch 21 is at the latch position, the courtesy switch lever 23 is separated from the actuator of the courtesy switch 41, and the courtesy switch 41 is turned off. When the latch 21 is in the unlatched position, the actuator of the courtesy switch 41 is pressed by the courtesy switch lever 23, and the courtesy switch 41 is turned on. For example, when the active lever 31 is at the unlock position, the position switch lever 32 is separated from the actuator of the position switch 42, and the position switch 42 is turned off. When the active lever 31 is at the unlock position, the actuator of the position switch 42 is pressed by the position switch lever 32, and the position switch 42 is turned on. For example, the control device displays the open / closed state and the locked / unlocked state of the vehicle door DR on the instrument panel according to the on / off state of the courtesy switch 41 and the position switch 42.

Here, the pitch (interval) between the pin insertion holes PH ₄₁₁ , PH _{411 is the same as} the pitch between the pin insertion holes PH ₄₂₁ , PH ₄₂₁ . However, the positional relationship between the mounting hole FH ₄₁₁ and the pin insertion hole PH ₄₁₁ is different from the positional relationship between the mounting hole FH ₄₂₁ and the pin insertion hole PH ₄₂₁ . Therefore, when the courtesy switch 41 and the position switch 42 are mounted by mistake, the positions of the mounting holes FH ₄₁₁ and FH ₄₂₁ and the boss BS are shifted, and the electric circuit device 40A is attached to the side wall 112. Cannot be assembled.

  As described above, the electric circuit device 40A includes the courtesy switch 41 and the position switch 42. In the following description, the specifications of the electric circuit device 40A will be referred to as full specifications. The specification of the electric circuit device 40B in which the dummy switch DS described below is mounted instead of the position switch 42 of the electric circuit device 40A is referred to as a courtesy switch specification. The specification of the electric circuit device 40C in which the dummy switch DS is mounted in place of the courtesy switch 41 of the electric circuit device 40A is called a position switch specification. In the vehicle door lock device 1 in which the electric circuit device 40B of the courtesy switch specification is assembled, the position switch lever 32 is omitted (see FIG. 12). Further, in the vehicle door lock device 1 to which the electric circuit device 40C of the position switch specification is assembled, the courtesy switch lever 23 is omitted (see FIG. 15). The full specification corresponds to the first specification of the present invention. The courtesy switch specification and the position switch specification correspond to the second specification and the third specification of the present invention.

The dummy switch DS is made of an electric insulating material (a synthetic resin material, a rubber material, or the like). The outer shape of the dummy switch DS is equivalent to the outer shape of the courtesy switch 41 and the position switch 42 (see FIGS. 9A and 9B). That is, the dummy switch DS includes the mounting hole FH _DS and the pin insertion hole PH _DS that respectively penetrate from the front surface S1 to the back surface S2. In addition, a protrusion DS1 is provided on the surface S1 of the dummy switch DS. Further, protrusions DS2 and DS2 are provided on the back surface S2 of the dummy switch DS.

When configuring the electric circuit device 40B (courtesy switch specification), as shown in FIGS. 10 to 12, the position switch 42 is arranged such that the surface S1 of the dummy switch DS faces the plate surfaces of the terminals Tb and Tc. to implement a dummy switch DS instead of the (insert the pin P to pin insertion hole _{PH DS).} On the other hand, when the electric circuit device 40C (position switch specification) is configured, as shown in FIGS. 13 to 15, the back surface S2 of the dummy switch DS faces the plate surfaces of the terminals Ta and Tc, and A dummy switch DS is mounted in place of the switch 41.

  As shown in FIG. 16A and FIG. 16B, the width of the root portion of the pin P at the distal end of the terminal Tb and the width of the pin P at the distal end of the terminal Tc are set to be larger than the width of the distal end portion. That is, the width of the pin P changes stepwise at the intermediate portion in the longitudinal direction. In other words, a step is formed at an intermediate portion of the pin P. As shown in FIG. 16A, when the dummy switch DS is arranged in the normal direction (when the front surface S1 faces the plate surface of the terminals Tb and Tc) instead of the position switch 42, the protrusion DS1 The dummy switch DS can be mounted without interfering with the stepped portion. On the other hand, as shown in FIG. 16B, when the dummy switch DS is arranged in the direction opposite to the normal direction instead of the position switch 42 (when the back surface S2 faces the plate surfaces of the terminals Tb and Tc). The projection DS2 interferes with the step of the pin P. Therefore, the dummy switch DS cannot be mounted. That is, erroneous insertion of the dummy switch DS is prevented.

As described above, when the dummy switch DS is disposed in the normal direction instead of the position switch 42, the position of the mounting hole FH _DS of the dummy switch DS is determined by the position of the mounting hole FH ₄₂₁ when the position switch 42 is mounted. Match position. Therefore, the dummy switch DS is locked to the boss BS. As a result, the distal end of the terminal Tc and the intermediate part of the terminal Tc are fixed to the side wall 112 via the dummy switch DS. That is, the dummy switch DS functions as the holding member of the present invention. Therefore, the terminals Ta and Tc are prevented from being short-circuited to other terminals.

On the other hand, when the erroneous insertion prevention mechanism as described above is not provided, the dummy switch DS can be mounted in a direction opposite to the normal direction. In this case, the position of the mounting hole FH _DS of the dummy switch DS is different from the position of the mounting hole FH ₄₂₁ when the position switch 42 is mounted. Therefore, the dummy switch DS cannot be assembled to the boss BS of the side wall portion 112.

  As shown in FIG. 17A, the width of the root portion of the pin P at the distal end of the terminal Ta and the width of the pin P at the distal end of the terminal Tc are set to be larger than the width of the distal end portion. That is, the width of the pin P changes stepwise at the intermediate portion in the longitudinal direction. In other words, a step is formed at an intermediate portion of the pin P. As shown in the figure, when the dummy switch DS is arranged in the normal direction instead of the courtesy switch 41 (when the back surface S2 faces the plate surface of the terminals Ta and Tc), the protrusion DS1 is pinned. The dummy switch DS can be mounted without interfering with the step of P. On the other hand, as shown in FIG. 17B, when the dummy switch DS is arranged in the opposite direction to the normal direction instead of the courtesy switch 41 (when the front surface S1 faces the plate surface of the terminals Ta and Tc). The projection DS1 interferes with the step of the pin P. Therefore, the dummy switch DS cannot be mounted. That is, erroneous insertion of the dummy switch DS is prevented.

As described above, when the dummy switch DS is arranged in the regular direction instead of the courtesy switch 41, the position of the mounting hole FH _DS of the dummy switch DS is set to the position of the mounting hole FH ₄₁₁ when the courtesy switch 41 is mounted. Match position. Therefore, the dummy switch DS is locked to the boss BS. As a result, the ends of the terminals Ta and Tc are fixed to the side wall 112 via the dummy switch DS. Therefore, the terminals Ta and Tc are prevented from being short-circuited to other terminals.

On the other hand, when the erroneous insertion prevention mechanism as described above is not provided, the dummy switch DS can be mounted in a direction opposite to the normal direction. In this case, the position of the mounting hole FH _DS of the dummy switch DS is different from the position of the mounting hole FH ₄₁₁ when the courtesy switch 41 is mounted. Therefore, the dummy switch DS cannot be assembled to the boss BS of the side wall portion 112.

  As described above, in the present embodiment, the switch terminal plate piece ST is shared by all specifications (full specification, courtesy switch specification, and position switch specification). Then, in the courtesy switch specification and the position switch specification, by using the dummy switch DS, the terminal on which the microswitch is not mounted is fixed to the side wall 112 via the dummy switch DS. According to this, there are fewer types of parts as compared to a case where different switch terminal plate pieces are manufactured for each of the full specification, courtesy switch specification and position switch specification. Therefore, it is possible to reduce the parts manufacturing cost, the parts management cost, and the like of the switch terminal plate piece ST.

  Further, the dummy switch DS functions as a substitute for the position switch 42 and also functions as a substitute for the courtesy switch 41. That is, the dummy switch DS is a component (common component) shared by the courtesy switch specification and the position switch specification. Therefore, the number of types of parts is smaller than in a case where a dummy switch as a substitute for the courtesy switch 41 and a dummy switch as a substitute for the position switch 42 are separately manufactured. Therefore, it is possible to reduce the component manufacturing cost, the component management cost, and the like of the dummy switch DS.

  Therefore, according to the present embodiment, it is possible to reduce the initial investment cost of the vehicle door lock device 1 (the manufacturing cost of the die for manufacturing the terminal and the die for manufacturing the dummy switch and the management cost thereof). At the same time, the productivity of the vehicle door lock device 1 can be improved.

  Furthermore, the implementation of the present invention is not limited to the above embodiment, and various changes can be made without departing from the purpose of the present invention.

  In the above embodiment, a subassembly in which various switches (or dummy switches DS) and the connector housing 44 are assembled to the switch terminal plate piece ST is manufactured in advance. Next, this subassembly is assembled to the side wall portion 112. Finally, the connection part CP is cut. However, instead of this, first, the switch terminal plate piece ST is placed on the side wall portion 112, and then various switches (or dummy switches DS) and the connector housing 44 are assembled to the switch terminal plate piece ST. Alternatively, the connecting portion CP may be cut.

  Further, the electric circuit device 40 includes two switches (the courtesy switch 41 and the position switch 42), but may include more switches. For example, a switch for detecting a rotational position of a key for locking and unlocking the vehicle door DR from outside the vehicle compartment may be further provided. In this case, it is preferable that the dummy switch DS be configured to be shared by all the switches. On the other hand, a different dummy switch (dedicated component) may be used for each switch. Further, the electric circuit device 40 may include an electric component different from the switch. For example, the electric circuit device 40 may include an electric motor that drives the active lever 31. In this case, a terminal as a conductive line for supplying electric power to the electric motor may be formed integrally with the switch terminal plate piece ST, and their connecting portions may be cut off. When other electric components are provided as described above, a terminal corresponding to the specification in which all the electric components are mounted may be used. Then, when a specification that does not use some electrical components is configured, a dummy component simulating the outer shape of the electrical component may be mounted.

  In the above embodiment, one of three specifications (full specification, courtesy switch specification and position switch specification) can be selected, but two specifications (full specification and specification using dummy switch DS) can be selected. One of the specifications may be selectable. That is, either one of the full specification and the courtesy switch specification may be selectable, or one of the full specification and the position switch specification may be selectable. When a switch different from the courtesy switch 41 and the position switch 42 (for example, a switch for detecting the rotational angle position of a key cylinder) can be mounted, the full specification mounting the switch and the switch are replaced with a dummy switch DS. Any of the specifications may be selectable.

  In the above embodiment, the connector housing 44 configured separately from the switch terminal plate ST is assembled to the switch terminal plate ST. However, by using an outsert molding method (insert molding method), The connector housing may be formed integrally with the switch terminal plate ST.
