Description

  The present invention relates to a connector, and more particularly to a connector of a type in which a large number of plug contacts and socket contacts are fitted and connected by rotating an operation lever.

  This type of connector has a structure as shown in FIGS. 1 to 4 attached to this specification (see Patent Document 1). The connector shown in FIG. 1 includes a plug-side connector 3 that accommodates a plurality of plug contacts 2 and a socket-side connector 5 that accommodates a plurality of socket contacts that fit into the plug contacts 2. Move relative to A to engage or disengage.

  FIG. 2 shows the plug-side connector 3. The plug-side connector 3 includes a first plug-side casing 6 having two opening surfaces and two engagements inserted with the plug body 8 interposed from one opening surface of the first plug-side casing 6. The plate 9 includes a plate-like second casing 15 for closing the opening surface along a rail formed at the edge of the one opening surface, and an operation lever 10. The first plug-side casing 6 and the flat plate-like second casing 15 are plated with a conductive material on the inner surface of each casing so as to be electrically connected to the socket-side connector 5 and to provide a shielding effect when the connector is fitted. ing.

  On the other hand, FIG. 3 shows the socket-side connector 5. The socket-side connector 5 includes a socket-side casing 11 having two engaging protrusions 41 projecting from each opposite surface at intervals, and is accommodated in the socket-side casing 11 together with the shield contacts 13. Are arranged in an arrayed state, and a guide plate 7 for guiding plug contacts.

  Next, the process of connecting the assembled plug-side connector 3 and socket-side connector 5 will be described with reference to FIG. First, the operation lever 10 assembled to the plug-side connector 3 is disposed at the position shown in FIG. In this state, the engagement plate 9 in the plug-side connector 3 is in a state in which the introduction portions 33a, 34a of the engagement grooves 33, 34 are aligned with the guide grooves 28, 29 formed in the plug-side casing 6. Be placed.

  In this state, the two connectors 3, 5 are arranged so that two engagement projections 41, two on one side, provided on the socket-side connector 5 are respectively inserted into the guide grooves 28, 29 of the plug-side connector 3. Place.

  When the connectors 3 and 5 are made to coincide with each other, the engagement protrusion 41 is disposed in the introduction portions 33a and 34a of the engagement grooves 33 and 34 that coincide with the guide grooves 28 and 29, respectively. Next, the operation lever 10 is rotated about the rotation shaft 10c to the position shown in FIG. As a result, the drive protrusion 10d provided at the tip of the operation lever 10 is moved along the arc hole 32 of the plug-side casing 6, thereby moving the engagement plate 9 in a direction orthogonal to the fitting direction. As a result, the engagement protrusions 41 arranged in the introduction portions 33a and 34a of the engagement grooves 33 and 34 of the engagement plate 9 can be moved in the inclined portions 33b and 34b of the engagement grooves 33 and 34. By this, it is moved in the fitting direction along the guide grooves 28 and 29 formed in the plug-side casing 6. In this way, the two engagement protrusions 41 on one side are simultaneously moved in the fitting direction by the engagement grooves 33 and 34 provided on the engagement plate 9 and parallel to each other. The fitting operation with the plug-side connector 3 is performed in a state in which the posture 5 is kept horizontal with respect to the fitting direction.

The conventional connector has been described above. In the connector as described above, the plug-side casing 6 is made of an insulating material by injection molding or the like because of its structure. Therefore, in order to achieve a shielding effect when the connector is fitted, the plug-side casing 6 and the flat plate-like second casing 15 need to be subjected to a process of plating a conductive material on the inner surface as described above.
In order to avoid this, if a method of manufacturing and processing the plug-side casing 6 with a metal is employed, it is difficult to manufacture with a structure that completes a casing constituted by the first and second casings as in Patent Document 1. Therefore, when a united casing that can be divided into two symmetrically is employed, the engagement plate needs to be made of metal in consideration of strength, so both the casing and the engagement plate are made of metal. , Engagement friction increases and is difficult to use.

  In the above conventional connector, the first plug-side casing 6 and the flat plate-like second casing are assembled so that a through-hole for routing the wiring connected to the plug contact is defined. The wiring direction of the cable, that is, the direction of the cable drawn from the plug contact side is uniquely determined, and for example, it is difficult to flexibly cope with a wiring system such as an underfloor type wiring or a ceiling type ladder wiring.

  Further, in the conventional connector, a stopper function is generally disclosed in which the operation lever is held at a predetermined position after completing the pivoting operation at the connector fitting position. Sometimes, another operation for releasing the stopper function is required, and a rotation operation for releasing the fitting is performed by two operations.

  Finally, in the conventional connector, for example, when the socket-side connector 5 is attached and fixed to the device side, the socket is usually inserted with the socket contact housing portion inserted through the window frame of the flat plate attached to the back surface of the device. The flange portion 40 of the side casing 11 is fixed to the mounting surface of the flat plate with fixing means such as screws. At that time, the socket-side connector 5 is attached to the side of the plug-side connector that faces the plug contact, and then the socket contact is inserted into the socket-side connector from the back side that faces the device for wiring work (hereinafter referred to as the front side). This is called a mounting method. For this reason, the wiring work for inserting the socket contact into the socket-side connector cannot be performed before the socket-side connector 5 is attached.

Japanese Patent No. 3492309

  Accordingly, a first object of the present invention is to provide a plug-side connector that is easy to assemble in the above-described connector and does not require a plating process in order to achieve a shielding effect. The second object of the present invention is that the operation lever is automatically fitted at the fitting position and can be detached by one operation while picking it with a finger when the connector is detached, which is easy to operate from an ergonomic point of view. Is to provide a simple stopper function. A third object of the present invention is to provide a connector that can perform wiring work such as insertion of a contact into a connector, not at the time of attaching the connector, but in an environment-friendly place such as a harness factory.

According to a preferred embodiment of the present invention, the connector of the present invention is a connector in which a plurality of plug contacts or a plurality of socket contacts are arranged in a pair of casings that are fitted to each other. Because
A) In one casing, at least two engaging protrusions are provided on a pair of opposite side surfaces in a direction orthogonal to the fitting direction of the casing,
B) The other casing
b1) Two or more engaging grooves parallel to each other for inserting the engaging protrusions are provided in each of a pair of opposing wall surfaces,
b2) In order to guide the engagement protrusions on the pair of opposing side surfaces in the insertion direction, the engagement groove includes an engagement plate provided in a direction inclined with respect to the insertion direction;
b3) comprising a cover plate that slidably holds the engagement plate between the wall surfaces;
b4) An operation lever for simultaneously moving the engagement plate in a direction orthogonal to the fitting direction is provided to be rotatable with respect to the pair of side surfaces.
It is characterized by that.

  For example, a plug-side connector is fixedly mounted on a flat panel panel on the apparatus side as one casing side, and a socket-side connector is a connector having an operation lever on the cable wiring side from the outside as the other casing side. . When the socket of the socket-side connector is made of metal and can be divided along the center line in the thickness direction, each of the divided casings is attached to the inner wall surface of the socket-side connector and attached to the side of the casing. A plastic cover plate is assembled, for example, with a metal engagement plate slidable by turning the lever, and then a socket body for supporting the socket contacts in a predetermined alignment state is predetermined. The desired socket side connector can be assembled by arranging and combining the socket side casings. At this time, the operation levers are fixed at symmetrical positions so as to operate symmetrically. Thus, when the plug-side connector is fitted, the operation lever is arranged at the initial position, and the two engagement projections positioned in the vertical direction with the casing of the plug-side connector are formed on the casing of the socket-side connector. Inserted into one engaging groove, and simultaneously with the sliding of the engaging plate by the rotation of the operating lever, the engaging protrusion is guided in the fitting direction along the inclined engaging groove provided on the engaging plate. . As described above, the mating connection is performed, and at this time, one of the engagement plates is interposed between the metal surface and the other between the plastic surfaces. Can slide.

  According to a preferred embodiment of the present invention, the other casing of the connector according to the present invention can be divided into two symmetrically and has openings that are inserted into at least two insides at equal distances from the corners, A through hole can be formed in cooperation with the other opening at the same time as the first opening is closed, and a through hole can be formed in cooperation with one opening at the same time as the other opening is closed. A clamp is provided.

  For example, when a socket-side connector is arranged as the other casing side, the socket side connector is provided with two openings that are inserted into the socket at equal distances from the corners of the socket-side casing that can be symmetrically divided. Cables with contacts can be pulled out from two directions, and can be adapted for cable routing in various situations. At that time, it is necessary to take measures to prevent dust and dirt from entering the casing of the two openings that are not used for drawing the wiring. Therefore, in one opening, a through hole to the opening is formed in cooperation with the means for holding or fixing the cable drawn by the socket contact wiring, and in the other opening, foreign matter is not mixed from the outside. In order to provide a clamp that can close the opening, a member that forms a through hole in one opening and a member that closes the other opening are provided along a surface that forms two openings. It is possible to provide a clamp having a structure connected at the corners.

  According to a preferred embodiment of the present invention, in the other casing of the present invention, the clamp fixes at least four edges of the other casing.

  For example, when the clamp forms a through hole for drawing out and guiding a contact wiring together with one of the two openings, an edge that defines a surface forming the one opening is formed on the casing. There may be provided fixing means for fixing so as not to divide. In addition, the other opening is closed by, for example, covering with an uneven or flat plate, and fixed so that the casing does not divide the edge defining the surface forming the other opening on the inside. Means can be provided on the concavo-convex or planar plate. Specifically, for example, the clamp is arranged on each surface having each opening and is provided with a refracting portion that refracts along the edge of the surface, thereby forming each surface so that the casing is not divided. The opposing edges, i.e. the four edges, can be fixed.

  According to a preferred embodiment of the present invention, the clamp of the present invention is characterized in that it has a locking projection inserted into a locking hole in each surface forming two openings of the other casing.

  For example, a total of four holes are formed on each of two surfaces forming the opening when the other casing, which can be divided into two, is symmetric with respect to the dividing line. The clamp has a portion covering at least a part of each surface having the opening, and two protrusions are formed from a part of each part, and the two protrusions are formed in the four holes. If it is made the structure which is each inserted and keeps a latching state, the latched state can be ensured also with respect to the division | segmentation direction of said other casing.

  According to a preferred embodiment of the present invention, in the connector of the present invention, the other casing is provided with a fixing protrusion, and the operation lever is provided with an elastically supported protrusion. The elastically supported protrusions are engaged by an operation of rotating the operation lever and function as a stopper of the operation lever.

  For example, using the other casing side as a socket-side connector, an operation lever is provided on each side of the casing of the socket-side connector that can be divided into two, and a fixing portion is provided so that each operation lever rotates symmetrically. From the fixed part, for example, a protrusion elastically supported by a spring or the like protrudes in a direction facing the casing, and the casing provides a stopper function of the operation lever at a position facing the protrusion by rotation. A fixing projection for projecting. In this structure, during the turning operation of the operation lever from the initial state, the tip of the protrusion protruding from the operation lever fixing portion and the fixed protrusion protruding from the casing abut and slide to complete the rotation. Lock in place. Thereby, the stopper function of the operation lever can be ensured by only one operation of the rotation operation. In addition, in the state of a stopper function in which the protrusion and the fixing protrusion are locked, when it is desired to release the locking, while holding the release knob formed on the fixing portion of the operation lever with a finger of one hand An operation of releasing the stopper function and an operation of returning the operation lever to the initial position on the same trajectory as the rotation can be performed.

  According to a preferred embodiment of the present invention, in the connector according to the present invention, an outer casing connected to the at least two engaging protrusions so as to arrange at least a part of the one casing inside, the outer casing and the A part of said other casing can be accommodated between one casing.

As in the conventional connector shown in FIGS. 1 to 4, for example, a socket-side connector is attached to a flat mounting frame such as a back panel of the apparatus, and the plug-side connector is used as a cable wiring side from the outside. In the case of fitting connection to the side connector, in the conventional socket side connector, as can be seen with reference to FIG. 1 and FIG. 3, the engagement protrusion 41 protrudes, so the fitting from the plug side connector to the socket side connector After mounting the flange part of the socket side connector on the rack with the front mount method on one side of the mounting rack facing in the direction, the harness work of the cable from the device side must be performed on the other side of the mounting rack However, in the present invention, a part of the conventional socket-side casing is connected to the engagement protrusion protruding from the casing of the conventional socket-side connector. Because the engaging projections are also housed in the frame body by the structure provided with the frame body formed to be arranged, for example, a window hole through which the frame body for housing the socket-side connector can be inserted is provided in the frame of the flat panel. Then, a rear mount system in which the socket-side connector is attached in the fitting direction from the socket-side connector to the plug-side connector is possible. As a result, the harness work is not limited to when the socket-side connector is attached to the rack. For example, the harness work and the contact wiring work are directly performed on the socket-side connector at a convenient place such as a harness factory and then moved to the work site. Easy and efficient workability can be provided by attaching the device to the rear mount system.
Further, if the frame body and the engaging protrusion are formed of a conductive material so as to accommodate the socket contact housing portion according to the present invention and are connected to each other, the space between the frame body and the socket contact housing portion is formed. Is formed so that the side surface of the casing of the plug-side connector and the inner surface of the frame body of the socket-side connector are brought into contact with each other. By configuring both of the frame members with a conductive material, the socket side and the plug side connector ground can be easily electrically connected without the need for plating the inner surface of the plug side casing as in the prior art. .

  In the prior art, the connector attached on the rack has been described as a socket-side connector. However, it is obvious to those skilled in the art that the connector mounted on the rack is included in the scope of the present invention, regardless of whether the connector is on the socket side or the plug side. As a connector, the connector attached to the cable wiring side from the outside is demonstrated as a socket side connector.

  FIG. 5 shows an overall perspective view of the connector according to the invention. The connector according to the present invention accommodates a socket-side connector 50 having a socket body 63 for accommodating a plurality of socket contacts 62 inside the socket-side casing 51, and a plurality of plug contacts 72 for fitting and connecting to the socket-side connector 50. And a plug-side connector 70.

  The socket-side connector 50 has a socket-side casing 51 that is formed of a conductive member plated to prevent corrosion and can be divided into two by a dividing line 56. The side wall 52 of the socket-side casing 51 has a plug side. Two engagement grooves 53 are formed in the connector fitting direction to accommodate the engagement protrusions 75 connected to the frame body 71 of the connector 70 inside. Further, the end portion of the operation lever 55 for fitting the connector is engaged and attached so as to slide in the sliding groove 54 formed between the two engaging grooves 53 of the socket side casing 51. It has been. Further, the socket side casing 51 has openings 58 and 59 which are inserted into the interior at equal distances from the corner edge 60 on the surface 57 and the surface 61.

  The plug-side connector 70 is attached by inserting the plug body 73 into a window frame of a metal frame 71 that covers a part of the plug body 73 that accommodates the plug contact 72. The plug contact 72 is disposed so as to face the socket contact 62 in the fitting direction. A total of four engaging projections 75 inserted from the opposing surfaces of the frame body 71 to be engaged with the engaging grooves 53 of the socket-side casing 51 protrude from the opposing surfaces at predetermined intervals. It is perpendicular to the pair of opposing surfaces of the body 73. Flat mounting flanges 74 are formed on the left and right ends in the longitudinal direction of the frame 71.

  FIG. 6 is an exploded perspective view of the socket-side connector 50. An engagement plate 86 that operates as described with reference to FIG. 4 is placed on the inner surface of the socket-side casing 51 that is divided into two so that the engagement plate 86 can be translated only in the longitudinal direction of the socket-side casing 51. Further, a plastic cover plate 82 covering the engagement plate 86 is attached. The operation lever 55 can be rotated about the shaft 88 on the side surface 52 of each socket-side casing 51, and the drive protrusion 87 located near one end of the operation lever along the rotation operation is 2 with respect to the side surface 52. The sliding hole 90 formed in the engaging plate 86 located between the two engaging grooves 53 and the arc hole 89 of the cover plate 82 slide. The socket-side connector 50 is assembled by appropriately arranging a socket body 63 to which a guide panel 77 for guiding a plug contact is attached in one socket-side casing 51 of the socket-side connector 50, and mounting the other socket-side casing 51. It attaches so that it may unite | combine and the assembly of the socket side casing 51 main body is completed. Thereafter, in order to operate each operation lever 55 symmetrically, a fixing member 94 in which a protrusion 95 that engages and locks with a fixing protrusion 113 (see FIG. 12) on the socket-side casing 51 is assembled by a spring. It functions as a fixed operating lever that is attached to the end of 55 opposite to the one end and cooperates.

  FIG. 7 is an exploded perspective view of the plug-side connector 70. 7 shows a socket body 73 that accommodates the plug contact 72 and a metal frame 71 that fixes the socket body 73 therein. A total of four engaging projections 75 project from each side surface of the frame body 71 in the vertical direction inside the frame body, two from one side. When the connector is fitted, the side surface 52 of the socket-side casing 51 is accommodated in the frame body 71 of the plug-side connector, so that the thickness of the operation lever 55 arranged on the side surface 52 and the frame body 71 come into contact with each other. . Therefore, a U-shaped notch is provided between the two engagement protrusions 75 on each side surface of the frame 71, and the engagement groove 53 on the side surface 52 of the socket-side casing 51 is fitted when the socket-side connector 50 is fitted. A sliding portion on one end side of the operation lever 55 formed between the two is accommodated to avoid contact between the portion and the frame body 71, and at the same time, there is no possibility that the casing is processed to add extra thickness or the like. . When assembling the plug-side connector 70, the plug body 73 is inserted in the direction of the arrow so as to be inserted into the window 98 from the inside of the conductive frame 71, and a part of the edge of the window frame 98 is plug body 73 at a predetermined position. Is fixedly locked (not shown) to a part of the frame and completed. At the end of assembly, the tips of the engagement protrusions 75 protruding from the frame 71 are positioned in a state orthogonal to the side surfaces of the socket body 73.

  8 (a) and 8 (b) are schematic diagrams for explaining the fitting operation of the connector according to the present invention. FIG. 8A shows a state in which the operation lever 55 is set to the initial position and the socket-side and plug-side connectors 50 and 70 are arranged at predetermined positions for fitting connection. FIG. 8B shows a state in which the operation lever 55 is rotated from the initial position to the completion position, and the socket-side and plug-side connectors 50 and 70 are engaged. When the operation lever 55 is rotated about the rotation axis 88 with respect to the socket-side casing 51 from the initial position to the end position, the drive protrusion 87 positioned near one end of the operation lever 55 is covered with the cover plate 82. The drive projection 87 pushes the side surface of the sliding groove 90 of the engagement plate 86 to translate the engagement plate 86 in the direction of the arrow. That is, the drive protrusion 87 and the sliding groove 90 cooperate with each other by turning the operation lever 55 to convert the engagement plate 86 into a linear motion, and at the same time, the four engagement protrusions 75 are simultaneously displaced in the connector fitting direction. Therefore, the contacts 62 and 72 on the socket side and the plug side are electrically connected.

  In FIG. 9, it is the perspective view which looked at the socket side casing 51 from another angle. The casing 51 has opening edges 105 and 106 that are equidistant from the intersecting corner edges of the two surfaces 57 and 61 and are inserted into the casing on each surface. The opening is provided to draw out the contact wiring in the casing, and the cable can be routed from one desired opening. When the cable is routed, a member called a clamp is usually used to guide and fix the cable. However, when the wiring drawn out from one opening is guided and fixed by a clamp, the other opening is preferably closed to prevent dust and dirt from entering the casing. As the closing means, a method of closing with a rubber-like bushing is conceivable. However, it is not preferable in terms of cost, and it is preferable to provide a means for closing the opening when the clamp member is attached. Therefore, the clamp provided with the said means is shown in FIG.

  The clamp 200 shown in FIG. 10 has two flat plates 201 and 202 extending from one corner edge. One flat plate 201 is formed in a rectangular shape, and the other flat plate 202 has a rectangular shape and has an opening 210 in the plane, and an intermediate portion 250 that extends in a vertical direction with respect to the plane from the opposite edge. The two fixing portions 221 formed in an arc shape are supported so that the cable can be easily fixed via the cable. The fixing portions 221 have a predetermined separation distance. For example, the fixing portions 221 are brought close to each other by the elastic force of the intermediate portion 250 by screwing screws or the like in cooperation with the four screw holes 260 of the flange portion 220. It is possible to fix the wiring cable. The procedure for attaching the clamp 200 to the socket-side casing 51 of the present invention will be described with reference to FIGS. A state in which the clamp 200 is attached to the socket-side casing 51 is shown in FIG. In FIG. 11, as shown in FIGS. 9 and 10, the locking projections 211 formed on the edge of the flat plate 201 are inserted into the locking holes 110, and the corner edges are then aligned to align the flat plate 201 of the clamp. Is disposed on the flat surface 57 of the socket-side casing 51, the flat plate 202 of the clamp 200 is disposed on the flat surface 61 of the socket-side casing 51, and finally the flat plate 201 is disposed at the edge of the flat plate 202. A state is shown in which the locking protrusion 212 protruding parallel to the surface is inserted into the locking hole 110 ′ to complete the assembly. The protrusions 211 and 212 are engaged with the holes 110 and 110 ′ so as to prevent the socket-side casing 51 from being divided. Further, refracting portions 240 and 230 refracted in the vertical direction from the plane are provided at the edges of the flat plates 201 and 202, respectively. As can be seen from FIG. 11, the refracting portions 240 and 230 are fixed so as to unite the split-side socket-side casing 51, and serve to fix the casing so as not to be divided. The opening of the flat plate 202 of the clamp substantially coincides with the opening in the flat surface 61 of the socket-side casing 51, and takes charge of drawing out the wiring in the casing. The fixing part 221 can fix the wiring cable by the means described above.

  In the clamp 200 of the present invention, the positional relationship of opening / closing is changed in addition to FIG. 11, the fixing portion 221 is arranged on the surface 57 side to realize the cable drawing, and the plane plate 201 side is arranged on the plane 61 side. Thus, the opening can be closed. That is, the other opening can be closed simultaneously with selecting a desired opening. Thereby, economical and efficient cable wiring can be performed.

  FIG. 12 shows a state in which the operation lever 55 is disposed at the initial position before the connector is fitted, and is rotated in the direction of the arrow. At that time, the tip of the protrusion 95 assembled by a spring (not shown) on the fixing member 94 of the operation lever 55 is on the slope of the fixing protrusion 113 formed on one surface of the socket-side casing 51 during the rotation. Sliding as in (b), the contact with the inclined surface is completed at the rotation completion position of the top end of the inclined surface while resisting the elastic force of the spring. When the contact is finished, the tip of the projection 95 gets over the top end and is fitted and locked between the surface of the socket side casing 51 and the inclined surface as shown in FIG. 13C by the elastic restoring force of the spring. The As described above, the stopper function of the operation lever 55 is provided. In order to release the locking, the projecting piece 96 and the fixing portion 94 are picked up so as to apply a force that resists the elastic force of the spring. Then, the locked state is released, and as shown in FIG. 13A, the tip of the projection 95 moves upward from the top of the fixed projection 113, so that the operation lever 55 is returned to the initial position in the picked state. Can be rotated. The socket-side casing 51 is provided with a stop contact portion 103 that contacts at the initial position and a stop contact portion 102 that stops the operation lever 55 at the rotation completion position. In addition, a protrusion 104 having an insertion hole is provided at the edge of the surface having the fixed protrusion 113, and in order to further ensure safety when the operation lever is fixed at the rotation end position, for example, The operating lever may be further fixed through a binding band (tie wrap) or wax thread.

  14 shows, for example, a plurality of insertion window holes provided vertically and horizontally on a flat panel (see reference numeral 300 in FIG. 15) for attaching a connector for performing cable wiring from the outside to the back surface of the apparatus, on the socket side or FIG. 14A shows a state in which one plug-side connector is attached, and FIG. 14A shows a conventional example as shown in FIGS. 1 to 4 as shown in the side view of FIG. 15A. Is a state in which the connector of the mold is attached to the flat panel 300 from the mating connector wiring side, and the upper stage shows a front view seen from the mating connector wiring side (front side), and the lower stage from the inside of the apparatus (rear side) Shown is a view. FIG. 14B shows a state in which the connector according to the present invention is attached to the flat panel 300 from the inside of the apparatus as shown in the side view of FIG. The front view seen from the (front side) is shown, The lower stage has shown the figure seen from the apparatus inside side (rear side).

  The attachment of the conventional connector shown in FIGS. 14A and 15A will be described. Conventionally, the connector contact body 8 is inserted into the window hole 301 of the flat panel 300 from the mating connector wiring side, and the flange portion 40 abutting on the mating connector wiring side surface of the flat panel 300 is fixed by screwing or the like. (Front mount method), and then, the wiring of the group of cables 310 connected on the inside of the apparatus is inserted and locked into the contact body 8 of the connector attached to the panel 300 for wiring work. The reason why the front mounting method is adopted is that in the case of the conventional connector shown in FIGS. 1 to 4, the locking protrusion 41 protrudes from the width direction of the window frame 300 of the flat panel 300. Since the locking projection 41 prevents the connector window frame 300 from being inserted, it can only be attached from the mating connector wiring side. Therefore, in the front mount system, the connector mounting operation and the cable wiring operation require two steps, and thus must be performed at the work site.

  Next, the attachment of the connector according to the present invention shown in FIGS. 14B and 15B will be described. In the case of the connector according to the present invention, the locking protrusion 41 (the engaging protrusion 75 in the present invention), which could not be inserted through the window hole 301 of the flat panel 300 in the conventional connector, is against each side of the contact body 73 that accommodates the contact. The frame body 71 is formed so as to be arranged in the vertical direction, and the frame body 71 is inserted through the window hole 301 of the flat panel 300 from the inside of the apparatus to the mating connector wiring side without causing an extra gap. The flange portion 74 that is in contact with the surface of the panel 300 on the inside of the apparatus can be fixed and attached with a screw or the like (rear mounting method). In the rear mount method, the group of cables 310 connected on the inside of the apparatus can be wired before the connector is attached to the flat panel 300. Therefore, there is no need to perform wiring at the work site. After wiring the connector at the place, it is only necessary to attach the connector at the site. Therefore, workability is greatly improved as compared with the conventional connector.

  Also, the polarization key 79 can be formed in the connector body. Thereby, the number of contacts accommodated can be increased. Further, FIG. 1 described in the prior art is provided with a guide pin 50. However, in the present invention, the guide pin is omitted based on the fact that the connector is fitted in parallel with each other, and the contact is similarly accommodated.
