Description

Connector misconnection preventing device and assembly kit thereof

Technical Field

The present invention relates to a device for preventing erroneous connection of a connector which can be mounted on a connector device, and an assembly kit thereof.

Background

Conventionally, a connector device having a simple structure in which a contact (terminal) is housed in a housing is known. The connector device can reduce the cost of a crimping tool and simplify tool management by making the types of contacts single (common) and making the types of housings multiple, and can use various devices.

In such a connector device, when a housing accommodating tab contacts (tab contacts) is fitted to a housing accommodating receptacle contacts, the tab contacts are fitted to the receptacle contacts to be electrically connected, but there is a problem that the tab contacts are connected to a wiring which should not be connected due to erroneous insertion.

Therefore, a connector device has been proposed which can easily confirm a normal fitting state and a fitting failure state of a housing (for example, see patent document 1). In patent document 1, a notch for preventing erroneous insertion is provided in one housing, a rib for preventing erroneous insertion is provided in the other housing, and these are correctly fitted to prevent erroneous connection (erroneous insertion).

Further, for example, the following configuration is also known: the key plug is inserted into a housing accommodating the socket contacts, and a part of the tab of the housing accommodating the tab contacts is screw-cut, thereby preventing erroneous insertion of the two.

Technical problem

However, the conventional method for preventing erroneous connection cannot satisfy one (common) requirement for the shape of the housing to be combined even in a plurality of types of connector devices in which wirings to be connected are different.

That is, in the conventional method, a process for determining a combination of connection (not common) is provided in the housing itself of the connector device. That is, even if the wiring is not connectable, the connection can be made as long as the form (combination of shapes) of the housing is the same.

Further, since the machining at the time of molding the housing and the thread cutting machining after molding are all irreversible machining, the combination of the fitted housings cannot be changed or the housing must be replaced, which leads to a problem of an increase in the number of working steps and cost.

In view of the above circumstances, the present invention provides a connector erroneous connection prevention device and an assembly kit thereof, which can easily prevent erroneous connection of a connector device and can prevent erroneous connection of a plurality of types of connector devices having different wirings to be connected, even when the housing is in one form.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same reference numerals denote the same components. In this and subsequent figures, some components are omitted as appropriate to simplify the drawings. In this and subsequent figures, the size, shape, thickness, and the like of the components are shown in an exaggerated manner as appropriate.

< overall construction >

Fig. 1A and 1B are schematic diagrams showing an example of a usage state of the connector erroneous connection prevention device 100 according to the present embodiment. The connector erroneous connection preventing device 100 according to the present embodiment can be attached to the connector device 20. The connector device 20 of the present embodiment is, for example, a square type connector device (for example, a dynamic connector or the like) in which the crimping shape of the wiring (electric wire) crimp contact is standardized, and includes a first connector 21 and a second connector 22. The first connector 21 has socket contacts 23 and a first housing 24 accommodating the socket contacts 23, and the second connector 22 has tab contacts 25 and a second housing 26 accommodating the tab contacts 25. The connector device 20 connects, for example, a tester (e.g., a tester for a semiconductor manufacturing apparatus) 31 and a test target apparatus (e.g., a semiconductor manufacturing apparatus) 32. Specifically, the first connector 21 is a connector on the tester 31 side, and the second connector 22 is a connector on the test object device 32 side.

The connector erroneous connection prevention device 100 prevents erroneous connection of one connector device 20 by a set (a pair) of units of a component on the first connector 21 side and a component on the second connector 22 side. That is, the connection is permitted only in the case of an appropriate combination of the first connector 21 and the second connector 22. Specifically, the connector erroneous connection prevention device 100 includes a first support 101 that supports a first housing 24 as a connector housing of the tester 31 from the outer periphery, a second support 110 that supports a second housing 26 as a connector housing of the device under test 32 from the outer periphery, and a state setting unit 200 provided in each of the first support 101 and the second support 110.

< status setting means >

Here, state setting section 200 of the present embodiment will be described with reference to fig. 2. This figure conceptually illustrates the

connector devices

20A and 20B and the state setting unit 200 of the connector erroneous connection prevention device 100. Fig. a is a side view showing the connector device 20A and the connector erroneous connection preventing device 100, and fig. B is a side view showing the connector device 20B and the connector erroneous connection preventing device 100. The first housings 24 and the second housings 26 of the

connector devices

20A and 20B have the same shape (the combined housings have one (common) shape, and hereinafter referred to as "one housing combination"), and different wires Wa to Wd are connected to the connector devices. The connector 20A connects the wires Wa to Wb ((a) in the figure), and the connector 20B connects the wires Wc to Wd ((B) in the figure), and the other combinations are not connectable. The description of the

connector devices

20A and 20B connected via the wiring lines Wa to Wd is omitted.

The state setting unit 200 has a plurality of setting members 201, and the plurality of setting members 201 are provided to each of the first support body 101 and the second support body 110 of the connector erroneous connection prevention device 100 and can be individually switched to be effective and ineffective. Here, "enabled" of the setting member 201 means that the setting member 201 protrudes from one support body side toward the other support body side (is arranged in a protruding state), and "disabled" means that the setting member 201 does not protrude (or is not arranged in a protruding state).

The state setting unit 200 can selectively set and switch the state of connection between the first casing 24 and the second casing 26 according to the form of the plurality of setting members 201, specifically, the valid and invalid states of the plurality of setting members 201 and the arrangement of the setting members 201 that are valid. The state of connection of the first housing 24 and the second housing 26 specifically refers to a non-connectable state and a plurality of connectable states.

The plurality of connectable states are states in which the plurality of types of connector devices 20 having different wires to be connected can be appropriately connected to each other, even though the housing is assembled in one type. For example, in fig. 2 (a) and 2 (B),

connector devices

20A and 20B are appropriately connected to each other.

Here, as shown in fig. 2a and 2B, even if any one of the setting members 201 is valid (fig. 2a shows that the setting member 201 on the second support body 110 side is valid, and fig. 2B shows that the setting member 201 on the first support body 101 side is valid), the setting member 201 facing the setting member 201 on the other support body side is invalid and does not interfere with each other (the setting member 201 is valid and does not interfere with each other), and the first casing 24 and the second casing 26 are allowed to be electrically connected.

On the other hand, as shown in fig. 2 (C), when the setting members 201 at the positions facing the first support 101 and the second support 110 are respectively activated during the fitting operation of the first casing 24 and the second casing 26, the setting members 201 are brought into an interference state if the fitting operation is advanced. When the setting member 201 is thus effective and brought into an interference state with the other, the first case 24 (wiring Wa) and the second case 26 (wiring Wd) become non-fittable (unfinishable), and as a result, the two become non-electrically connectable.

In the present embodiment, although it will be described in detail later, the setting members 201 located at the facing positions are all configured to protrude into a common space. That is, in the case of a combination of the first housing 24 and the second housing 26 that allows connection (the corresponding setting members 201 do not interfere with each other), when one of the first support 101 side and the second support 110 side activates the setting member 201, the setting member 201 at the opposing position of the other support is inevitably deactivated.

Here, for the sake of simplicity of explanation, the effective setting members 201 are provided one on each of the first support 101 and the second support 110, but a plurality of setting members 201 are arranged in the state setting unit 200 of each of the first support 101 and the second support 110. That is, by arbitrarily or selectively activating a part of the plurality of setting members 201, it is possible to set the arrangement mode of the plurality of setting members 201 which are activated and which are in a non-interference state with each other in different modes for one type of casing combination.

Fig. 2 (D) shows an arrangement pattern of the setting member 201 (hereinafter, also simply referred to as "effective setting member") which is effective and in a non-interference state with the other in the case of fig. 2 (a). In the case where the connector device 20A shown in fig. 2a is in the first connectable state, the first support 101 and the second support 110 are arranged in the mode a (the mode of the entire two supports, the mode A1 and the mode A2 in pair) in which the setting members 201 do not interfere with each other on the first support 101 side and the second support 110 side.

Further, (2) of fig. 2 (D) is a layout pattern of the effective setting members 201 in the case of fig. 2 (B). In the case where the connector device 20B shown in fig. 2 (B) is in the second connectable state, the first support 101 and the second support 110 are arranged in the mode B (mode of the entire two supports, mode B1, mode B2 in pair) in which the setting members 201 do not interfere with each other on the first support 101 side and the second support 110 side. In the modes B and a, the positions of the effective setting members 201 are different in the case of using one support (for example, the first support 101) as a reference, and for example, if the first support 101 in which the effective setting members 201 are arranged in the mode a (A1) and the second support 110 in which the effective setting members 201 are arranged in the mode B (B2) are arranged to face each other and the first casing 24 and the second casing 26 are fitted to each other, a part of the effective setting members 201 interfere with each other and the two cannot be connected to each other ((C) of fig. 2). The same applies to the combination of the first support 101 in the pattern B and the second support 110 in the pattern a.

As described above, in the plurality of connectable states, the positions of the effective setting members 201 (the positions of the effective setting members 201 of the first support body 101 and the second support body 110 as a whole) among the plurality of setting members 201 are made different for each connectable state, and the set of the connectable first housing 24 and the connectable second housing 26 is configured to allow the fitting of the first housing 24 and the second housing 26 without interference of the setting members 201 with each other.

Hereinafter, more specifically, a case will be described as an example in which the state setting unit 200 includes a plurality of screw holes 105 provided in the first support body 101, a plurality of screw holes 113 provided in the second support body 110, and a setting member 201, and the setting member 201 is a plurality of screws 150 that can be selectively attached to and detached from each of the plurality of screw holes 105, 113.

< first support >

Fig. 3 is an external view showing the first support 101 of the connector erroneous connection prevention device 100. Fig. 3 (a) is an external perspective view, fig. 3 (B) is a plan view, fig. 3 (C) is a front view as viewed from the connecting direction of connector device 20, and fig. 3 (D) is a side view. In the following description, for convenience of explanation, a moving direction in inserting and removing the connector device 20 is referred to as an inserting and removing direction T, a direction perpendicular to the inserting and removing direction T in a plan view of fig. 3 (B) is referred to as a width direction W, and a direction perpendicular to the inserting and removing direction T and the width direction W in a front view of fig. 3 (C) is referred to as a thickness direction D.

The first support 101 has at least a holding portion 103 for holding at least a part of the first housing 24. Here, the first support 101 is, for example, a box-shaped member (box-shaped member) in which a first cassette 101A and a second cassette 101B having (substantially) the same shape are arranged to face each other, and a part of the first casing 24 is held by a substantially frame-shaped holding portion 103 created by the facing arrangement of the first cassette 101A and the second cassette 101B.

Since the first cassette 101A and the second cassette 101B have the same configuration, the first cassette 101A will be described. The second box 101B is shown with the symbol end of each component of the first box 101A changed to "-B".

The first cartridge 101A includes a main body 102A having a substantially rectangular parallelepiped shape, and a holding portion 103A provided on one side of the main body 102A (the side facing the second connector 22 when the connectors are connected). The holding portion 103A has protruding portions 104A protruding in the thickness direction D at both ends in the width direction W. The protrusion 104A is provided at a position separated from the end of the main body 102A.

The

main bodies

102A and 102B are disposed to face each other so that the contact surfaces 108A and 108B abut each other, and the holding

portions

103A and 103B create the accommodating portion 106 ((D) of fig. 3). Although described later, the accommodating portion 106 accommodates the flange portion of the first housing 24, and the protruding

portions

104A and 104B engage with a part of the first housing 24 like a wedge. In this way, the outer periphery of the first housing 24 is held by the frame-shaped holding portion 103.

The first support body 101 has a plurality of screw holes 105 in a part thereof, specifically, in an opposing surface OS opposing the second support body 110. In this example, the screw hole 105 is provided on the facing surface OS of the holding portion 103 facing the second support body 110. More specifically, holding portion 103 has a plurality of comb teeth 107 protruding in insertion/removal direction T, and one screw hole 105 is provided on each of opposing surfaces OS between respective comb teeth 107 that oppose second support body 110, and in this example, four screw holes 105 are provided on each of

main bodies

102A and 102B so as to sandwich first housing 24, and a total of eight screw holes 105 are provided. Each screw hole 105 has the same configuration. The connector erroneous connection prevention device 100 includes a plurality of screws (not shown) that can be screwed into the respective screw holes 105, and the screws can be selectively attached to and detached from the respective screw holes 105 after the connector erroneous connection prevention device has been installed. That is, the space between the comb teeth 107 is the screw accommodation space S.

In this example, when the screw 150 is attached to any of the screw holes 105, the screw 150 serves as the effective setting member 201. When the screw 150 is removed from the screw hole 105, the screw 150 becomes the ineffective setting member 201.

The screw hole 105 to which the screw is attached and the number thereof can be set to any position for each connector erroneous connection preventing device 100, but interference with the screw 150 that is effective in the combined second support body 110 is avoided. The number of screws 150 may or may not be the same as the number of screw holes 105.

The kind of the screw is desired to be a screw whose head has a certain height (length in the insertion and extraction direction T in the case of being attached to the screw hole 105) and which can be attached even in a space-saving manner, and for example, a hexagon socket screw (cap bolt, button cap bolt, or the like) can be used.

The protruding length of the comb teeth 107 in the insertion/removal direction T is, for example, the same as the length of the tip of the head of a screw when the screw is attached to the screw hole 105, or the length of the tip of the head of the screw which does not protrude from the comb teeth 107.

For example, a fixing screw hole 109 for a fixing screw (not shown) for fixing the clamped state of the first housing 24 is provided at a predetermined position of the main body 102 (fig. 3B). However, the present invention is not limited to this, and the clamping state of the first housing 24 may be fixed by providing engagement portions on the

bodies

102A and 102B and engaging them.

< second support >

Fig. 4 is an external view of second support body 110, fig. 4 (a) is a front view as viewed from the connection direction of connector device 20, and fig. 4 (B) is a side view.

The second support body 110 includes, for example, a rectangular flat plate-shaped main body 111 and a holding portion 112 through which the second casing 26 can be inserted. Here, the holding portion 112 is, for example, a rectangular opening provided in the main body 111. However, the present invention is not limited to this, and may be configured as follows: two pieces of the same-shaped main body 111 having a recess with one open end provided on one side of a rectangle are prepared, and the two pieces of the main body 111 are combined so that the recesses face each other, thereby forming a rectangular opening. The main body 111 is, for example, a plate-like member that can be attached to a part of the test object device 32, or a member that constitutes a part of a housing of the test object device 32.

The second housing 26 is inserted through the holding portion 112 from one surface side. For example, in the case of the second housing 26 having a flange portion, the flange portion is engaged with and held by an end portion of the holding portion 112. The second housing 26 may be a flat box-shaped housing having no flange.

The second support body 110 has a plurality of screw holes 113 in a part thereof, specifically, in an opposing surface OS opposing the first support body 101. In this example, the screw holes 113 are provided at positions facing each of the screw holes 105 of the first support body 101 when the first housing 24 held by the first support body 101 is fitted to the second housing 26 held by the second support body 110. Specifically, four screw holes 113 are provided along the long side of the rectangular holding portion 112 that is long in the width direction W so as to sandwich the second housing 26, and a total of eight screw holes 113 are provided outside the holding portion. Then, if a screw is attached to any of the screw holes 113 of the second support body 110 and the first support body 101 is disposed to face and approach the second support body 110, the screw of the second support body 110 moves toward the screw accommodation space S. When the screw of the first support body 101 is already accommodated in the screw accommodation space S (when the screw of the first support body 101 is effective), the screw of the first support body 101 interferes with the screw of the second support body 110, and the movement of the second support body 110 is restricted (see fig. 9F). When the screw is not accommodated in the screw accommodation space S (when the screw of the first support 101 is not effective), the screw of the second support 110 is accommodated in the screw accommodation space S (see fig. 7F).

In the second support body 110, the screw holes 113 have the same configuration. The connector erroneous connection prevention device 100 includes a plurality of screws (not shown) that can be screwed into the screw holes 113, and the screws can be selectively attached to and detached from the screw holes 113 after the connector erroneous connection prevention device has been installed and detached.

In this example, when the screw 150 is attached to any of the screw holes 113, the screw 150 serves as the effective setting member 201. When the screw 150 is removed from the screw hole 113, the screw 150 becomes the ineffective setting member 201.

The screw hole 113 to which the screw is attached and the number thereof can be set to an arbitrary position for each connector erroneous connection prevention device 100, but effective screw interference with the first support 101 to be combined is avoided. As the screw 150 that can be attached to the first support 101, for example, a socket head cap screw (cap bolt, button cap bolt, or the like) can be used. In this example, all the screws 150 are the same size (height of the head 150H). The number of screws 150 may or may not be the same as the number of screw holes 105, 113. In this example, the number of screw holes 105, 113 is the same.

The screw receiving space S of the first support body 101 is common to the second support body 110. That is, if a screw 150 (setting member 201) of the first support 101 or the second support 110 is enabled, that is, mounted in the screw hole 105 and a part (head) thereof is present in the screw housing space S, and the screw is enabled at the opposing position of the other support, the heads 150H of the screws 150 interfere with each other, and the connecting operation of the connector device 20 is restricted. That is, the non-connectable state (interference state) in the present embodiment refers to a state in which the heads 150H of the screws (socket head cap screws) 150 interfere with each other in the screw housing space S provided in the facing surface OS of the first support body 101 facing the second support body 110 (see fig. 9C).

For example, a fixing screw hole 114 for a fixing screw (not shown) for fixing the held state of the second housing 26 is provided at a predetermined position of the main body 111. However, the present invention is not limited to this, and the main body 111 may be provided with an engaging portion that engages with the second housing 26 to be fixed and held.

< method of Assembly >

The connector erroneous connection prevention device 100 according to the present embodiment can be provided as an assembly kit 50 including the first support 101, the second support 110, and a plurality of screws, for example. Referring to fig. 5 and 6, a method of assembling the connector erroneous connection prevention device 100 will be described.

Fig. 5 is a schematic diagram showing a step of supporting the first casing 24 by the first support 101. Fig. 5 (a) is a plan view before assembly, and illustrates the inside of the first and

second cartridges

101A and 101B after disassembly. Fig. 5 (B) is a side view before assembly, fig. 5 (C) is a plan view after assembly, fig. 5 (D) is a side view after assembly, and fig. 5 (E) is a plan view after assembly.

The screws 150 are inserted, for example, from the outside (the side facing the second support body 110) of the appropriate screw holes 105 so that the heads 150H thereof are positioned in the screw receiving spaces S of the comb teeth 107, and are fixed to the inside of the first and

second cases

101A and 101B by nuts (not shown). Here, as an example, screws 150 are attached to the screw holes 105C and 105G of the eight screw holes 105A to 105H (see fig. 5 (E)).

Thereafter, as shown in fig. 5B, a flange portion 24F of the first case 24 is disposed between the holding portion 103A of the first cartridge 101A and the holding portion 103B of the second cartridge 101B (fig. 5B), the first cartridge 101A and the second cartridge 101B are brought into contact with each other so that the flange portion 24F engages with the protruding

portions

104A, 104B, and a fixing screw (not shown) is screwed into the fixing screw hole 109 (fig. 5C to 5E).

In this manner, the first casing 24 is supported by the first support 101. As shown in fig. 5 (D), a part of the first housing 24 is accommodated in the accommodating portion 106.

Fig. 6 is a schematic view showing a method of supporting the second case 26 by the second support body 110. Fig. 6 (a) is a front view before assembly as viewed from the connecting direction, fig. 6 (B) is a side view before assembly, fig. 6 (C) is a front view after assembly as viewed from the connecting direction, fig. 6 (D) is a side view after assembly, and fig. 6 (E) is a back view after assembly.

As shown in fig. 6, the second housing 26 is inserted into the holding portion 112 of the main body 111, and for example, the flange portion 26F of the second housing 26 is screwed into the fixing screw hole 114. In addition to this, the present invention is, (C) E in FIG. 6

As shown in fig. 6 (E), a screw 150 is attached to a desired screw hole 113 of the main body 111. For example, the screw 150 is inserted from the outside (the side facing the first support 101) of the appropriate screw hole 113, and is fixed to the back surface side of the main body 111 by a nut (not shown). Here, as an example, the screw 150 is attached to the screw holes 113C and 113G among the eight screw holes 113A to 113H. The head 150H of the screw 150 protrudes toward the facing surface OS of the main body 111 facing the first support 101.

In this manner, the second housing 26 is supported by the second support body 110. An edge portion 26T (fig. 6 a, 6B, and 6D) of the second housing 26, which is a receiving opening of the first housing 24, is exposed on the front surface of the second support body 110 (the facing surface OS facing the first support body 101), and a main body portion accommodating the tab contacts is supported so as to protrude toward the rear surface side of the second support body 110 (fig. 6D).

< connectable State (non-interference State) >

Fig. 7 is a schematic diagram showing a method of using the connector erroneous connection prevention apparatus 100 (connection example). For example, the fitting operation between the first housing 24 supported by the first support 101 shown in fig. 5 and the second housing 26 supported by the second support 110 shown in fig. 6 is described, and is a schematic diagram showing an example of a connectable state (first connectable state).

Fig. 7 (a) is a schematic diagram showing the position of the effective screw 150 in the first support body 101, and is a front view seen from the direction of the second support body 110 to be fitted. Fig. 7B is a schematic diagram showing the position of the active screw 150 in the second support body 110, and is a rear view seen from the same direction as fig. 7 a (the back side (inside) direction of the second support body 110). Fig. 7 (C) is a view showing fig. 7 (a) and 7 (B) superimposed on each other. Fig. 7D is a side view of the first support body 101 and the second support body 110 before joining, fig. 7E is a side view after joining, fig. 7F is a plane (top view) near the facing surface after joining, the left side shows an upper portion (upper portion in fig. 7D) of the screw holes 105 and 113, and the right side shows a lower portion of the screw holes 105 and 113.

As shown in fig. 7 a and 5E, in the first support body 101, screws 150 (effective as setting members 201) are attached to the screw holes 105C and 105G. As shown in fig. 7B, 6C, and 6E, screws 150 are attached to the screw holes 113C and 113G of the second support body 110 (effective as a setting member 201). In this case, the positions of the screws 150 effective for the first support body 101 and the second support body 110 do not interfere with each other when the first support body 101 and the second support body 110 are opposed to each other as shown in fig. 7 (C) and 7 (F).

Referring to fig. 7 (D) and 7 (E), if the first housing 24 is inserted into the second housing 26 and the fitting operation is performed, the four screws 150 are accommodated in the respective different screw accommodation spaces S without interfering with each other.

Therefore, the facing surfaces OS of the first support 101 and the second support 110 substantially abut against each other, and fitting, that is, electrical connection between the first case 24 and the second case 26 is permitted (fig. 7 (E)).

Fig. 8 is a schematic diagram showing an example of another connectable state (second connectable state) in which the combination of the first casing 24 and the second casing 26 is the same as that in fig. 7 but the wiring is different. Fig. (a) to (C) are schematic views corresponding to fig. 7 (a) to 7 (C).

Fig. 8 (a) is a schematic view showing the position of the effective screw 150 in the first support body 101 in the second connectable state, fig. 8 (B) is a schematic view showing the position of the effective screw 150 in the second support body 110, and fig. 8 (C) is a view showing the effective screw 150 superimposed on fig. 8 (a) and 8 (B).

As shown in fig. 8 (a), in the second connectable state, for example, in the first support body 101, screws 150 are attached to the screw holes 105B and 105D (effective as the setting member 201). As shown in fig. 8B, a screw 150 is attached to the screw hole 113D of the second support body 110 (effective as a setting member 201). In this case, the positions of the screws 150 effective for the first support 101 and the second support 110 do not interfere with each other when the first support 101 and the second support 110 are opposed to each other as shown in fig. 8 (C). Therefore, in this case as well, as shown in fig. 7 (D) and 7 (E), if the first housing 24 is inserted into the second housing 26 and the fitting operation is performed, the three screws 150 are accommodated in the different screw accommodation spaces S without interfering with each other.

Therefore, the facing surfaces OS of the first support 101 and the second support 110 substantially abut against each other, and fitting, that is, electrical connection, between the first case 24 and the second case 26 is permitted.

< non-connectable State (interference State) >

Fig. 9 is a diagram illustrating a fitting operation of the second housing 26 of the connector device 20 in the first connectable state shown in fig. 7 and the first housing 24 of the connector device 20 in the second connectable state shown in fig. 8, and is a schematic diagram showing an example of a case where the housings that are not permitted to be connected are erroneously connected.

Fig. 9 (a) is a schematic view showing the position of the effective screw 150 in the first support body 101, and is a re-view of fig. 8 (a), and fig. 9 (B) is a schematic view showing the position of the effective screw 150 in the second support body 110, and is a re-view of fig. 7 (B). Fig. 9 (C) is a view showing fig. 9 (a) and 9 (B) superimposed on each other. Fig. 9D is a side view of the first support body 101 and the second support body 110 before fitting, fig. 9E is a side view of both in an interference state, fig. 9F is a plan view (top view) of the vicinity of the facing surfaces in the interference state, the left side shows the upper portions (upper portions in fig. 9D) of the screw holes 105 and 113, and the right side shows the lower portions of the screw holes 105 and 113.

In this case, as shown in fig. 9 a, screws 150 are attached to the screw holes 105B and 105D of the first support body 101 (effective as a setting member 201). As shown in fig. 9B, screws 150 are attached to the screw holes 113C and 113G of the second support body 110 (effective as setting members 201). When the first support body 101 and the second support body 110 are opposed to each other, as shown in fig. 9 (C), the screw 150 of the screw hole 105B of the first support body 101 interferes with the screw 150 of the screw hole 113C of the second support body 110.

Referring to fig. 9 (D), if the first housing 24 is inserted into the second housing 26 and the fitting operation is performed, the screw 150 of the screw hole 105D of the first support body 101 and the screw 150 of the screw hole 113G of the second support body 110 are respectively accommodated in different screw accommodation spaces S. However, the screws 150 of the screw holes 105B of the first support body 101 have been accommodated in the screw accommodating spaces S of the screws 150 intended to accommodate the screw holes 113C of the second support body 110.

Therefore, the screws 150 interfere with each other, and movement thereof is restricted until the facing surfaces OS of the two

support bodies

101 and 110 abut against each other, and fitting (that is, electrical engagement) between the first housing 24 and the second housing 26 is not possible (fig. 9 (E) and 9 (F)).

That is, the state of non-connectable state is a state in which the head 150H of the screw 150 on the first support body 101 side and the head 150H of the screw 150 on the second support body 110 side accommodated in the screw accommodation space S interfere with each other, and the plurality of connectable states are states in which the head 150H on the first support body 101 side and the head 150H on the second support body 110 side do not interfere with each other in the screw accommodation space S (left view of fig. 7 (F)). In the plural connectable states, depending on the position of the screw 150 attached to the second support body 110 side, the head 150H on the second support body 110 side is not necessarily accommodated in the screw accommodation space S. For example, in fig. 7B, when the screws 150 are not attached to the screw holes 113G (all the screws 150 are not attached to the second support body 110 side), the heads 150H on the second support body 110 side are not accommodated in the screw accommodation spaces S, but can be accommodated if the heads 150H are present.

That is, in the screw housing space S, the first housing 24 and the second housing 26 can be connected as long as the screw 150 on the first support body 101 side and the head 150H of the screw 150 on the second support body 110 side do not interfere with each other (see fig. 7F).

As described above, in the present embodiment, the screws 150 can be attached to the first support body 101 supporting the first casing 24 and the second support body 110 supporting the second casing 26, respectively, and the first support body 101 and the second support body 110 can be set in the non-connectable state or the connectable state according to the attachment positions of the screws 150 (the presence or absence of the screws 150 in the predetermined screw holes 105, 113).

Specifically, in the case of the connectable connector device 20, the screw 150 is attached to a position where the first support 101 supporting the first housing 24 and the second support 110 supporting the second housing 26 do not interfere with each other, and in the case of the non-connectable connector device 20, the screw 150 is attached to a position where the first support 101 and the second support 110 interfere with each other.

In particular, the connector erroneous connection prevention device 100 has one type of configuration for the first housing 24 and the second housing 26, but it is possible to make the connection impossible for an improper combination of a plurality of types of connector devices 20 having different wirings to be connected.

That is, according to the present embodiment, it is possible to provide a connector erroneous connection prevention device and an assembly kit thereof, which can easily prevent erroneous connection of the connector device 20 and prevent erroneous connection (connection is permitted only in the case of an appropriate combination of the first housing 24 and the second housing 26) even in a plurality of types of connector devices (different in connection wiring) configured by using a combination of the first housing 24 and the second housing 26 in one form.

In the case of a non-connectable combination, the number of screw holes 105 and 113 may be different as long as the pair of screws 150 attached to the opposing positions interfere with each other, and as a result, the first housing 24 and the second housing 26 are not electrically connectable.

The shape and size of the first holding portion 103 of the first support 101 and the second holding portion 112 of the second support 110 may be changed. For example, the first support 101 may be configured such that the first cassette 101A and the second cassette 101B can be adjusted in the width direction W, the thickness direction D, and the like by a slide mechanism or the like. The second support body 110 may be configured by a unit in which a plurality of (for example, four) flat plate portions are slidably connected, and the shape and size of the holding portion 112 that forms the opening portion may be changed by the movement of the flat plate portions.

In particular, the first support body 101 may be configured such that the screw hole 105 has a thread (having a female screw structure) formed on the inner side thereof, for example, and the position of the screw 150 can be changed from the outside in a state of supporting the first housing 24 (in an assembled state).

The connector erroneous connection prevention device 100 may be configured by a set of the first support 101, the second support 110, and the plurality of screws 150 assembled in a box-like (case-like) state, and in this case, the first housing 24 may be inserted (fitted) into the first support 101.

State setting section 200 of the present embodiment may be configured to be able to switch between valid and invalid states. Therefore, in the above-described embodiment, the screw 150 and the screw holes 105 and 113 to which the screw 150 is attached have been described as an example of the state setting means 200, but the present invention is not limited to this. For example, the state setting unit 200 may be a button-shaped member that is provided in the first support 101 and the second support 110 and can be recessed (depressed)/protruded with respect to them, or may be a member that becomes effective when protruded and becomes ineffective when recessed (depressed). Further, the state setting means 200 may be a pin-shaped member provided in the first support 101 and the second support 110 so as to be peelable/(re) attachable, or may be a member that becomes effective in the case of adhesion (re-attachment) and becomes ineffective in the case of peeling.

It should be noted that the connector erroneous connection preventing device 100 of the present invention is not limited to the above-described embodiment, and it is obvious that various modifications can be made within a range not departing from the gist of the present invention.
