Description

The present invention relates to a connector support attachable to a connector device.

2. Description of the Related Art Conventionally, a connector device having a simple structure in which contacts (terminals) are accommodated in a housing is known. While this connector device uses a single (common) contact type, it uses a wide variety of housings to reduce (the cost of) crimping tools and simplify tool management. Diversity can be provided.

In such a connector device, when the housing accommodating the tab contacts and the housing accommodating the receptacle contacts are fitted together, the tab contacts are fitted to the receptacle contacts to establish an electrical connection. Connection with wiring that should not be connected becomes a problem.

For this reason, a connector device has been proposed that allows easy confirmation of a properly fitted state and a defectively fitted state of the housing (see, for example, Patent Document 1). In Patent Document 1, one housing is provided with an erroneous insertion prevention notch, and the other housing is provided with an erroneous insertion prevention rib. It has become so.

Further, for example, a configuration is known in which a keying plug is inserted into a housing containing a receptacle contact and a part of a tab of the housing containing a tab contact is screwed off to prevent erroneous insertion of both.

Japanese Patent No. 6619723

However, the conventional erroneous connection prevention method cannot meet the demand to combine a plurality of types of connector devices with different wirings to be combined with one type (common) of housing shape.

That is, in the conventional method, the housing itself of the connector device is processed to specify (not make common) the combination of connections. In other words, even wiring that cannot be connected can be connected if the shape of the housing (combination of shapes) is the same.

In addition, since the processing during molding of the housing and the threading processing after molding are all irreversible processing, it is not possible to change the combination of housings to be fitted, or replacement of the housing is required, which increases work man-hours. There is also the problem of increased costs.

In view of such circumstances, the present invention is intended to easily prevent erroneous connection of a connector device, and to provide an erroneous connection for each of a plurality of types of connector devices having different wiring to be connected, even if the shape of the housing is one. The object is to provide a connector support that can prevent this.

The present invention has a first cassette and a second cassette, and a holding portion created by the facing arrangement of the first and second cassettes can hold a part of the housing of the connector. The connector support is characterized in that a plurality of setters can be arranged in the holding portion, and the state of the holding portion can be changed by the arrangement of the plurality of setters.

ADVANTAGE OF THE INVENTION According to the present invention, it is possible to easily prevent erroneous connection of a connector device, and to prevent erroneous connection of each of a plurality of types of connector devices having different wirings to be connected, even if the shape of the housing is one. A support can be provided.

<Overall composition>
FIG. 1 is a schematic diagram showing an example of a usage state of a connector erroneous connection prevention device 100 of this embodiment. The connector erroneous connection prevention device 100 of this embodiment can be attached to the connector device 20 . The connector device 20 of this embodiment is, for example, a rectangular connector device (for example, a dynamic connector) in which the crimp shape of wiring (electric wire) crimp contacts is standardized, and has a first connector 21 and a second connector 22 . The first connector 21 has receptacle contacts 23 and a first housing 24 containing them, and the second connector 22 has tab contacts 25 and a second housing 26 containing them. Also, the connector device 20 connects, for example, a tester (for example, a tester for semiconductor manufacturing equipment) 31 and a device under test (for example, a semiconductor manufacturing equipment) 32 . Specifically, the first connector 21 is a connector on the tester 31 side, and the second connector 22 is a connector on the device under test 32 side.

The connector erroneous connection prevention device 100 prevents erroneous connection of one connector device 20 by a unit consisting of a first connector 21 side constituent member and a second connector 22 side constituent member. In other words, connection is permitted only in the case of an appropriate combination of the first connector 21 and the second connector 22 . Specifically, the connector misconnection prevention device 100 includes a first support 101 that supports the first housing 24, which is the connector housing of the tester 31, from the outer periphery, and a second housing 26, which is the connector housing of the device under test 32. It has a second support 110 that supports it from the outer periphery, and state setting means 200 provided on each of the first support 101 and the second support 110 .

<State setting means>
Here, the state setting means 200 of this embodiment will be described with reference to FIG. This figure is a diagram for conceptually explaining the connector devices 20A and 20B and the state setting means 200 of the connector erroneous connection prevention device 100. As shown in FIG. 2A is a side view showing the connector device 20A and the connector misconnection prevention device 100, and FIG. 4B is a side view showing the connector device 20B and the connector misconnection prevention device 100. FIG. The connector devices 20A and 20B have the same shape of the first housing 24 and the same shape of the second housing 26. , and different wirings Wa to Wd are connected to each of them. The connector device 20A connects the wires Wa-Wb ((A) in the figure), and the connector device 20B connects the wires Wc-Wd ((B) in the figure). A description of the devices to which the connector devices 20A and 20B are connected via the wires Wa to Wd is omitted.

The state setting means 200 is provided on each of the first support 101 and the second support 110 of the connector erroneous connection prevention device 100, and has a plurality of setters 201 capable of individually switching between valid and invalid states. Here, "effective" of the setting element 201 means that the setting element 201 is protruded from one support side toward the other support side (arranged in a protruding state), and "ineffective" means that the setting element 201 is not protruded ( or do not arrange).

The state setting means 200 is configured to select the first housing 24 and the second housing 26 according to the aspect of the plurality of setting elements 201, specifically, the enabled/disabled states of the plurality of setting elements 201 and the arrangement of the setting elements 201 to be enabled. connection state can be selectively set and switched. Specifically, the state of connection between the first housing 24 and the second housing 26 includes a non-connectable state and a plurality of connectable states.

A plurality of connectable states is a state in which a plurality of types of connector devices 20, which are combinations of one type of housing but have different wires to be connected, can be appropriately connected. For example, in FIGS. 1A and 1B, connector devices 20A and 20B are properly connected to each other.

Here, as shown in FIGS. 1A and 1B, a setter 201 is effective (the second support 110 side in FIG. Even if the setting element 201 on the 101 side is effective), the setting element 201 facing the setting element 201 on the other support side is disabled and does not interfere with each other (when the setting element 201 is effective and does not interfere with the other side) state), electrical connection between the first housing 24 and the second housing 26 is permitted.

On the other hand, as shown in FIG. 4C, when the first housing 24 and the second housing 26 are fitted together, the setters 201 at positions facing each other in the first support 101 and the second support 110 are activated. In this case, if the fitting operation proceeds, the setters 201 will soon come to interfere with each other. In this way, when the setter 201 is effective and interferes with the other party, the fitting between the first housing 24 (wiring Wa) and the second housing 26 (wiring d) is not possible (incomplete). cannot be electrically connected.

In this embodiment, as will be described in detail later, the setters 201 at opposing 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 permits connection (the corresponding setters 201 do not interfere with each other), one of the first support 101 side and the second support 110 side When the setter 201 is enabled in , the setter 201 at the opposite position of the other support is always disabled.

Also, here, for the sake of simplicity of explanation, one effective setter 201 is provided for each of the first support member 101 and the second support member 110. A plurality of setters 201 are arranged in each state setting means 200 . In other words, by arbitrarily and selectively making some of the plurality of setters 201 effective, the arrangement pattern of the setters 201 that are effective and in a non-interfering state with the mating member for one type of housing combination can be changed in different patterns. can be set multiple times.

(1) in FIG. 4D shows an arrangement pattern of the setter 201 (hereinafter simply referred to as "effective setter") that is effective and non-interfering with the other party in the case of FIG. is. The connector device 20A shown in FIG. 4A is in the first connectable state, and in this case, the effective setter 201 of the first support 101 and the second support 110 is the The second support 110 side and the second support 110 side are arranged in a pattern A (pattern for both supports as a whole or paired patterns A1 and A2).

In addition, (2) in FIG. 4D is an arrangement pattern of effective setters 201 in the case of FIG. 4B. The connector device 20A shown in FIG. 4B is in the second connectable state. The second support 110 side and the second support 110 are arranged in a pattern B (pattern for both supports as a whole or paired patterns B1 and B2). In pattern B and pattern A, the position of the effective setter 201 with respect to one of the supports (for example, the first support 101) is different. is placed, and the second support 110, on which the setter 201 effective in pattern B (B2) is placed, are arranged to face each other, and the first housing 24 and the second housing 26 are fitted. Then, part of the effective setter 201 interferes and the two cannot be connected ((C) in the figure). The same applies to the combination of the pattern B first support 101 and the pattern A second support 110 .

In this way, in a plurality of connectable states, the position of the setter 201 to be enabled among the plurality of setters 201 (the effective position of the first support 101 and the second support 110 as a whole) is determined for each connectable state. The position of the setter 201 to be connected) is made different, and for a connectable set of the first housing 24 and the second housing 26, the fitting of the first housing 24 and the second housing 26 is performed without causing the setters 201 to interfere with each other. configured to allow

More specifically, the state setting means 200 includes a plurality of screw holes 105 provided in the first support 101 , a plurality of screw holes 113 provided in the second support 110 , and a plurality of setters 201 . A case in which a plurality of screws 150 are selectively attachable to and detachable from screw holes 105 and 110 will be described as an example.

<First support>
FIG. 3 is an external view showing the first support 101 of the connector erroneous connection prevention device 100. As shown in FIG. 1A is an external perspective view, FIG. 1B is a plan view, FIG. 1C is a front view seen from the connecting direction of the connector device 20, and FIG. In the following description, for convenience of explanation, the moving direction when inserting and removing the connector device 20 is the insertion/extraction direction T, the direction perpendicular to the insertion/extraction direction T in the plan view of FIG. A direction perpendicular to the insertion/removal direction T and the width direction W in the front view is referred to as a thickness direction D. As shown in FIG.

The first support 101 has, for example, at least a holding portion 103 that clamps at least a portion of the first housing 24 . Here, as an example, the first support 101 is a case-shaped member (cassette-shaped member) in which a first cassette 101A and a second cassette 101B having (substantially) the same shape are arranged facing each other. A part of the first housing 24 is sandwiched by a substantially frame-shaped holding portion 103 created by the facing arrangement of the two cassettes 101B.

Since the configurations of the first cassette 101A and the second cassette 101B are the same, the first cassette 101A will be described. The configuration of the second cassette 101B is indicated by changing the suffix of each configuration of the first cassette 101A to "-B".

The first cassette 101A has a substantially rectangular parallelepiped main body 102A and a holding portion 103A provided on one side of the main body 102A (the side facing the second connector 22 when the connector is connected). 103 A of holding|maintenance parts have the protrusion part 104A which protrudes in the thickness direction D at the both ends of the width direction W. As shown in FIG. The projecting portion 104A is provided at a position away from the end of the main body 102A.

The main bodies 102A and 102B are arranged to face each other so that the contact surfaces 108A and 108B are in contact with each other, and the holding portions 103A and 103B create a housing portion 106 ((D) in the same figure). As will be described later, the accommodating portion 106 accommodates the flange portion of the first housing 24, and the projecting portions 104A and 104B are engaged with a portion of the first housing 24 like wedges. In this manner, the outer periphery of the first housing 24 is clamped by the frame-shaped holding portion 103 .

The first support 101 has a plurality of screw holes 105 in a portion thereof, more specifically, in the surface OS facing the second support 110 . In this example, the screw hole 105 is provided on the surface OS of the holding portion 103 facing the second support 110 . More specifically, the holding portion 103 has a plurality of comb teeth 107 protruding in the insertion/removal direction T, and one comb tooth 107 is provided between each comb tooth 107 on the surface OS facing the second support 110 . Four screw holes 105 are provided in each of the main bodies 102A and 102B so as to sandwich the first housing 24, for a total of eight screw holes 105. As shown in FIG. Each screw hole 105 has the same configuration. The connector erroneous connection prevention device 100 has a plurality of screws (here, not shown) that can be screwed into the screw holes 105, and screws can be subsequently and selectively attached to and detached from the screw holes 105. It's becoming That is, the space between each comb tooth 107 is the screw accommodation space S. As shown in FIG.

In this example, when a screw 150 is attached to one of the screw holes 105, the screw 150 becomes a valid setter 201. FIG. Also, when the screw 150 is removed from the screw hole 105 , the screw 150 becomes an invalid setter 201 .

In which screw holes 105 screws are attached and the number of screws can be set at any position for each connector misconnection prevention device 100, but interference with the screws 150 effective in the second support 110 to be combined is avoided. . The number of screws 150 and the number of screw holes 105 may or may not be the same.

Desirably, the type of screw has a head that has a certain height (the length in the insertion/removal direction T when attached to the screw hole 105) and can be attached in a small space. bolts, button cap bolts, etc.) can be adopted.

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

Further, for example, a fixing screw hole 109 for a fixing screw (not shown) for fixing the holding state of the first housing 24 is provided at a predetermined position of the main body 102 (FIG. 1B). However, the present invention is not limited to this, and engagement portions may be provided on the main bodies 102A and 102B, and the first housing 24 may be fixed in the sandwiched state by engagement thereof.

<Second support>
4A and 4B are external views of the second support 110. FIG. 4A is a front view as seen from the connecting direction of the connector device 20, and FIG. 4B is a side view.

The second support 110 has, for example, a rectangular plate-shaped main body 111 and a holding portion 112 through which the second housing 26 can be inserted. Here, as an example, the holding portion 112 is a rectangular opening provided in the main body 111 . However, the present invention is not limited to this. For example, two bodies 111 having the same shape and having a recess with one end open on one side of the rectangle are prepared, and the two bodies 111 are combined so that the recesses face each other to form a rectangular shape. It may be configured to form an opening. The main body 111 is, for example, a plate-like member that can be attached to a part of the device under test 32 or a member that constitutes part of the housing of the device under test 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 engages the end portion of the holding portion 112 and is held. The second housing 26 may be straight and box-shaped without flanges.

The second support 110 has a plurality of screw holes 113 on a portion thereof, more specifically, on the surface OS facing the first support 101 . In this example, the screw hole 113 is formed in the screw hole of the first support 101 when the first housing 24 held by the first support 101 and the second housing 26 held by the second support 110 are fitted together. 105 are provided at positions facing each other. Specifically, a total of eight screw holes 113 are provided along the long sides of a rectangular holding portion 112 that is long in the width direction W so as to sandwich the second housing 26 , four screw holes 113 on each outer side thereof. Then, when a screw is attached to one of the screw holes 113 of the second support 112 and the first support 101 and the second support 110 are arranged to face each other and are brought close to each other, the screw of the second support 112 is inserted into the screw accommodation space S. move towards When the screw of the first support 101 is already accommodated in the screw accommodation space S (when the screw of the first support 101 is enabled), the screws of the first support 101 and the second support 110 are It interferes and restricts the movement of the second support 220 (see FIG. 9(F)). When no screw is accommodated in the screw accommodation space S (when the screw of the first support 101 is invalid), the screw of the second support 110 is accommodated in the screw accommodation space S (see FIG. 7(F)). .

Each screw hole 113 in the second support 110 also has the same configuration. The connector erroneous connection prevention device 100 has a plurality of screws (not shown here) that can be screwed into the respective screw holes 113, and screws can be subsequently and selectively attached to and detached from the respective screw holes 113. It's becoming

In this example, when a screw 150 is attached to one of the screw holes 113, the screw 150 becomes a valid setter 201. FIG. Also, when the screw 150 is removed from the screw hole 113 , the screw 150 becomes an invalid setter 201 .

The positions to which screws are to be attached and the number thereof can be arbitrarily set for each connector misconnection prevention device 100, but interference with the effective screws of the combined first support 105 is avoided. This screw is also similar to the screw 150 that can be attached to the first support 101, and for example, a hexagonal socket screw (cap bolt, button cap bolt, etc.) can be employed. In this example, all screws 150 have the same size (height of head 150H). The number of screws 150 and the number of screw holes 105 and 113 may or may not be the same. In this example, the numbers of screw holes 105 and 113 are the same.

The screw accommodation space S of the first support 101 is shared with the second support 110 . That is, the screw 150 (setter 201) with the first support 101 or the second support 110 is effective, that is, it is attached to the screw hole 105, and a part (head) thereof exists in the screw accommodation space S. In this case, when the screw is activated at the opposite position of the other support, the heads 150 of the screws 150 interfere with each other, restricting the connection operation of the connector device 20 . That is, the unconnectable state (interference state) in the present embodiment means that a screw (hexagon socket screw) This is a state in which the heads 150H of 150 interfere with each other (see FIG. 9(C)).

Further, 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 an engaging portion may be provided on the main body 111 and engaged with the second housing 26 to fix the holding state.

Therefore, the opposing surfaces OS of the first support 101 and the second support 110 are substantially in contact with each other, allowing the fitting of the first housing 24 and the second housing 26, that is, electrical connection (FIG. 7 ( E)).

FIG. 8 is a schematic diagram showing an example of another connectable state (second connectable state) in which the same combination of the first housing 24 and the second housing 26 as in FIG. 7 is used, but the wiring is different. 7A to 7C are schematic diagrams corresponding to FIGS. 7A to 7C.

1A is a schematic diagram showing the effective positions of the screws 150 in the first support 101 in the second connectable state, and FIG. 1B is the effective positions of the screws 150 in the second support 110. FIG. 2C is a schematic view showing the same figure (A) and the same figure (B) superimposed.

As shown in FIG. 4A, in the second connectable state, for example, screws 150 are attached to the screw holes 105B and 105D of the first support 101 (effective as the setter 201). . Further, as shown in FIG. 2B, in the second support 110, a screw 150 is attached to the screw hole 113D (effective as the setter 201). In this case, the positions of the screws 150 that are effective in the first support 101 and the second support 110 are such that the first support 101 and the second support 110 face each other as shown in FIG. does not interfere in either case. Therefore, in this case as well, as shown in FIGS. 6(D) and 6(E), when the first housing 24 is inserted into the second housing 26 and the fitting operation is performed, these three screws 150 are engaged with each other. They fit in separate screw housing spaces S without interference.

Therefore, the facing surfaces OS of the first support 101 and the second support 110 are substantially in contact with each other, allowing the fitting of the first housing 24 and the second housing 26, that is, electrical connection.

<<Unconnectable state (Interference state)>>
FIG. 9 shows the second housing 26 of the connector device 20 in the first connectable state shown in FIG.
FIG. 10 is a diagram for explaining the fitting operation of the connector device 20 in the second connectable state shown in FIG. .

8A is a schematic diagram showing the positions of the effective screws 150 in the first support 101, and FIG. FIG. 7B is a schematic diagram showing the position of 150 and is a reproduction of FIG. 7(B); (C) of the same figure is a diagram showing (A) and (B) of the same figure superimposed. 1D is a side view of the first support 101 and the second support 110 before fitting, FIG. 1E is a side view of both in an interference state, and FIG. is a plane (top view) near the opposing surface of the screw holes 105 and 113, and the upper portion of the screw holes 105 and 113 (the upper portion in the same figure (D)) is shown on the left, and the lower portion of the screw holes 105 and 113 is shown on the right.

In this case, as shown in FIG. 1A, screws 150 are attached to the screw holes 105B and 105D of the first support 101 (effective as the setter 201). Further, as shown in FIG. 2B, screws 150 are attached to screw holes 113C and 113D in the second support 110 (effective as setters 201). When the first support 101 and the second support 110 face each other, as shown in FIG. 150 interferes.

Referring to FIG. 9(D), when first housing 24 is inserted into second housing 26 and a fitting operation is performed, these four screws 150 do not interfere with each other, and are attached to first support 101. Referring to FIG. The screw 150 in the screw hole 105D and the screw 150 in the screw hole 113G of the second support 110 are accommodated in different screw accommodating spaces S, respectively. However, the screw receiving space S in which the screw 150 of the screw hole 113C of the second support 110 is to be accommodated already has the screw hole 105B of the first support 101.
of screws 150 are accommodated.

For this reason, these screws 150 interfere with each other, restricting movement before the opposing surfaces OS of both supports 101 and 110 come into contact with each other, and fitting (that is, electrically connecting) the first housing 24 and the second housing 26 together. ) is disabled ((E) and (F) in the figure).

In other words, the unconnectable state is a state in which the head portion 150H of the screw 150 on the side of the first support 101 accommodated in the screw accommodation space S and the head portion 150H of the screw 150 on the side of the second support 110 interfere with each other. It can be said that the plurality of connectable states are states in which the head portion 150H on the side of the first support 101 and the head portion 150H on the side of the second support 110 do not interfere in the screw housing space S (FIG. 7 ( F) left). In the multiple connectable state, depending on the position of the screw 150 attached to the second support 110 side, the head 150H on the second support 110 side may not always be accommodated in the screw accommodation space S. For example, in FIG. 7B, when the screw 150 is not attached to the screw hole 113G (and no screw 150 is attached to the second support 110 side), the screw accommodation space S is filled with the second support. The head 150H on the 110 side is not accommodated, but can be accommodated if there is a head 150H.

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

As described above, in this embodiment, the screws 150 can be attached to the first support 101 that supports the first housing 24 and the second support 102 that supports the second housing 26. The first supporting body 101 and the second supporting body 102 can be set to a non-connectable state or a connectable state depending on (presence or absence of screws 150 in predetermined screw holes 105 and 113).

Specifically, in the case of the connectable connector device 20, the first support 101 that supports the first housing 24 and the second support 110 that supports the second housing 26 are positioned so as not to interfere with each other. While the screw 150 is attached, in the case of the connector device 20 that cannot be connected, the screw 150 is attached at a position such that the first support 101 and the second support 110 interfere with each other.

In particular, in the connector misconnection prevention device 100, the shape of the first housing 24 and the second housing 26 is one type. can be disabled.

That is, according to the present embodiment, erroneous connection of the connector device 20 can be easily prevented, and a combination of the first housing 24 and the second housing 26 of one type is used (connected wiring is different). ) A connector erroneous connection prevention device and its assembly kit that prevents erroneous connection even with a plurality of types of connector devices (allows connection only in the case of an appropriate combination of the first housing 24 and the second housing 26) can provide

In the case of a non-connectable combination, it is sufficient that the first housing 24 and the second housing 26 become electrically non-connectable as a result of interference between the pair of screws 150 attached at opposing positions. The number of screw holes 105, 113 may differ.

Also, 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, in the first support 101, the first cassette 102A and the second cassette 102B may be adjustable in the width direction W and the thickness direction D by a slide mechanism or the like. Alternatively, the second support 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 becomes the opening portion can be changed by moving the flat plate portions. good.

In particular, regarding the first support 101, the threaded hole 105 is formed with a screw thread on its inner side (to have a female thread structure), so that the screw 150 can be inserted while the first housing 24 is supported (assembled). The position may be changeable from the outside.

In addition, the connector misconnection prevention device 100 may be configured by a set of the first support 101 assembled in a case shape (box shape), the above-described second support 110, and a plurality of screws 150. In that case, the first housing 24 may be inserted (fitted) into the first support 101 .

The state setting means 200 of this embodiment may be any device as long as it can be switched between valid and invalid. Therefore, in the above-described embodiment, the screw 150 and the screw holes 105 and 113 for attaching the screw 150 were described as an example of the state setting means 200, but the present invention is not limited to this. For example, the state setting means 200 is provided on the first support 101 and the second support 110, and may be a button-like member that can be pushed into (depressed)/protruded from these, and becomes effective when protruded. , may be invalidated when immersed (pressed down). Further, the state setting means 200 may be a pin-shaped member that is detachably/(re)adherably provided to the first support 101 and the second support 110, and is effective when adhered (re-adhered). and may become invalid when peeled off.

The connector misconnection prevention device 100 of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
