[Industrial applications]

 The present invention relates to a connector used for connecting boards to each other or connecting flat cables to boards in consumer equipment, office automation equipment, etc., and is composed of a receptacle connector and a plug connector which can be fitted to each other. It relates to a two-piece type connector.

[0002]

[Prior art]

 Conventionally, there are various types of connectors for connecting boards to each other and connecting a flat cable to the boards. The main ones are receptacle connectors A as shown in FIGS. 5 (a) to 5 (c). And a plug connector B as shown in FIGS. 3 (d) to 3 (f).

In the receptacle connector A, a large number of receptacle contacts D are inserted and arranged in a receptacle body C made of an insulating material, and a fitting protrusion E is formed on the receptacle body C. A large number of pin insertion / extraction openings H into which the pin contacts F of the plug connector B are inserted are formed on the bottom surface.

In the plug connector B, a large number of pin contacts F are inserted and arranged in a plug body J, which is also formed of an insulating material, and a fitting recess K is formed on the upper portion of the plug contacts F. It is projected in the fitting recess K. Then, when the fitting protrusion E of the receptacle connector A is fitted into the fitting recess K, the tip of the pin contact F is inserted into the pin insertion / extraction opening H of the receptacle body C, and the receptacle contact D and the pin. The contact F is electrically connected.

Further, in order to smoothly fit the receptacle connector A and the plug connector B into this connector, as shown in FIGS. 5D to 5F, the length of the fitting recess K of the plug body J is increased. Guide claws M are formed so as to project upward at the center of both ends in the direction, and the guide claws M are formed so that their ends project inside the fitting recess K, and FIG. As shown in (c), guide grooves N into which the guide claws M can be fitted are formed at both ends in the longitudinal direction of the fitting protrusion E of the receptacle body C. As a result, when the fitting protrusion E of the receptacle connector A is pushed into the fitting recess K of the plug connector B, the guide claw M of the plug connector B is first inserted into the guide groove N of the receptacle connector A, and thereafter. The fitting protrusion E of the receptacle connector A is inserted into the fitting recess K of the plug connector B.

In order to prevent the connector A and the plug connector B from being mated with each other at the time of mating (mis-mating), the receptacle body C is fitted as shown in FIG. 5C. An outwardly projecting projection O is formed on the side surface of the fitting convex portion E in the width direction, and a groove P recessed outward is provided on the side surface of the fitting recess K of the plug body J in the width direction as shown in FIG. 5D. There is. As a result, the protrusion O and the groove P fit only when the two connectors A and B are fitted in the correct direction as shown in FIG. I am doing it.

Further, in the receptacle connector A of FIG. 5, the width of the portion of the projection O is larger than the width of the fitting recess K of the plug connector B in the middle in the longitudinal direction, so that it is shown in FIG. 6 (a). As described above, even when the receptacle connector A is slantedly fitted into the plug connector B and slid from the lateral direction, the fitting convex portion E does not enter the fitting concave portion K in the middle of sliding, so The tip of the protruding pin contact F is not pushed by the tip of the fitting convex portion E 1 (it is not pushed), and the tip of the pin contact F is prevented from becoming slanted or bent.

[0008]

[Problems to be solved by the device]

 Both connectors A and B shown in FIG. 5 have a projection O and a groove P on one side if they are closely observed, so that the fitting direction can be correctly identified, but it is said that they are busy working in a factory or the like. Since there is a guide claw M and a guide groove N for guiding the fitting of both connectors A and B in the center, the fitting is performed from directly above in FIG. 6B (in the direction of the arrow in the drawing), the same drawing (d). Even when sliding from the side of () (in the direction of the arrow in the figure), it is often impossible to determine whether or not the fitting direction is correct until both connectors A and B are set to the push-in position. Therefore, a work procedure is adopted in which both connectors A and B are first pushed in as they are, and when they are not pushed in properly (when they are erroneously mated), they are turned over again and mated again. For this reason, it takes extra time to fit the two connectors A and B, resulting in inefficiency, or if the connectors are pushed hard as they are in the case of the previous incorrect fitting, the connectors may be damaged.

Further, when the size of the connector is reduced, the thickness of the outer periphery of the fitting recess K of the plug connector B is inevitably reduced, so that the protrusion amount of the protrusion O formed on the fitting protrusion E of the receptacle connector A is naturally. Limited. For this reason, when the receptacle connector A and the plug connector B are forced in the opposite directions and forced, the outer periphery of the fitting recess K is pushed outward as shown in FIG. 6 (c) or (e). The tip of the fitting convex portion E may enter the inside of the fitting concave portion K, and the outer peripheral wall may be damaged. Further, as shown in FIG. 6 (a), when the receptacle connector A is pushed laterally, the tip of the fitting convex portion E inside the fitting concave portion K pushes the pin contact F of the plug connector B. It was sometimes lost.

Further, since the protrusions O for preventing bumping and for erroneous fitting are provided only on one side of the receptacle connector A, it is the same as when the receptacle connector A is slid sideways as shown in FIG. 6A. The protrusion O often enters the fitting recess K. However, if you do not notice it, you can slide it as it is to push the pin contact F, or if you slide it to the end and push it in as it is, you may damage the outer peripheral wall of the fitting recess K as described above. However, there was a problem that the mis-mating prevention structure did not function sufficiently.

An object of the present invention is to prevent the body of the receptacle connector from sticking the plug pin of the plug connector when mating the receptacle connector of the connector and the plug connector, and to ensure quick and reliable mating. It is to provide a connector that can be checked.

[0016]

[Action]

 In the connector according to claim 1 of the present invention, the fitting protrusion 3 of the receptacle connector 5 is provided at both ends in the longitudinal direction, at both corners thereof, and protrudes outward in the width direction of the fitting protrusion 3 and the fitting recess 11 of the plug connector 13. Positioning projections 15 and 16 wider than the width are formed, and even if an attempt is made to push the fitting protrusion 3 of the receptacle connector 5 downward into the fitting recess 11 of the plug connector 13 as shown in FIG. The positioning projections 15 and 16 do not enter the fitting recess 11 in the middle of the fitting recess 11, but the positioning projections 15 and 16 slide on the outer peripheral wall 30 of the fitting recess 11. Therefore, the end of the fitting convex portion 3 does not poke the pin contact 12 in the fitting concave portion 11 and push and bend it during the sliding.

In the connector according to the second aspect of the present invention, since the protruding lengths of the positioning protrusions 15 and 16 at both ends in the longitudinal direction of the fitting protrusion 3 are different, the fitting direction of the receptacle connector 5 and the plug connector 13 is wrong. If so, the longer positioning protrusion 15 of the fitting protrusion 3 of the receptacle connector 5 comes into contact with the shorter positioning groove 18 of the plug connector 13, so that it does not proceed any further and the mis-fitting can be surely checked. .

In the connector according to the third aspect of the present invention, the positioning protrusions 15 and 16 have different widths. Therefore, if the fitting direction of the receptacle connector 5 and the plug connector 13 is wrong, the positioning protrusions 15 and 16 will be positioned in the positioning grooves. It is possible to prevent erroneous fitting without fitting into 17 and 18.

In the connector of claim 4 of the present invention, the guide claw 20 is formed eccentrically in the width direction of the fitting recess 11 of the plug connector 13, and the guide groove 21 into which the guide claw 20 is fitted is formed in the receptacle connector. Since the fitting protrusion 3 of FIG. 5 is formed eccentrically in the width direction, if the fitting directions of both connectors 5 and 13 are matched as shown in FIG. 3, the fitting protrusion 3 is guided by the guide claw 20. The part 3 is fitted into the fitting recess 11, but if the fitting directions of both connectors 5 and 13 are not correct, even if the fitting is attempted from directly above as shown in FIG. As shown in FIG. 6C, the fitting protrusion 3 guided by the guide claw 20 is displaced from the fitting recess 11 and thus is not fitted. Also, even if an attempt is made to slide and fit from the side as shown in FIG. 4 (d), the guide groove 21 and the guide claw 20 are not misaligned and fitted as shown in FIG. 4 (e). 5 and 13 are not fitted.

[0020]

Embodiment 1 An embodiment of the connector of the present invention will be described in detail with reference to FIGS. This connector comprises a receptacle connector 5 shown in FIGS. 1 (a) to 1 (c) and a plug connector 13 shown in FIGS. 1 (d) to 1 (f).

In the receptacle connector 5, a large number of receptacle contacts 2 made by processing a thin metal plate having electrical conductivity are inserted and arranged in a receptacle body 1 formed of an insulator such as plastic. In the lower part of the receptacle connector 5, a large number of pin insertion / extraction openings 4 into which the pin contacts 12 from the plug connector 13 are inserted are formed, and this portion is also a fitting recess of the plug connector 13 described below. It is a fitting convex portion 3 which is fitted to 11.

The plug connector 13 includes a plug body 10 made of an insulating material similar to that of the receptacle connector 5, and arranged with a large number of pin contacts 12 made by processing a thin electrically conductive metal plate. It was On the upper surface of the plug connector 13, there is formed a fitting recess 11 having the same shape as the fitting projection 3 of the receptacle connector 5. The tip of the pin contact 12 projects into the fitting recess 11.

As shown in FIGS. 1D to 1F, guide claws 20 are formed at both ends in the longitudinal direction of the fitting recess 11 of the plug connector 13. A part of each of the guide claws 20 projects into the fitting recess 11, and a tip of the guide claw 20 projects above the upper surface of the plug connector 13. Further, both guide claws 20 are similarly formed at positions slightly decentered from the center of the fitting recess 11 in the width direction.

Guide grooves 21 for receiving the guide claws 20 are formed at both ends of the fitting protrusion 3 of the receptacle connector 5 in the longitudinal direction. The guide groove 21 is eccentric in the width direction of the fitting projection 3 by the same eccentricity as the guide claw 20. This orientation is such that the receptacle connector 5 and the plug connector 13 are fitted properly as shown in FIG. When you do so, make sure that the eccentric positions match each other properly.

Positioning protrusions 15 and 16 are formed at both ends of the fitting protrusion 3 of the receptacle connector 5 at both ends in the longitudinal direction. As shown in FIG. 2 (a), both of the positioning projections 15 and 16 are formed so as to project outward by a dimension D 1 from the width of the central portion of the fitting projection 3. In addition, one of the positioning protrusions 15 is formed so as to protrude as much as the dimension C toward the outside in the longitudinal direction of the fitting protrusion 3 from the other positioning protrusion 16.

Positioning grooves 17 and 18 are formed at both corners of the fitting recess 11 of the plug connector 13 at both ends in the longitudinal direction. As shown in FIG. 3, the positioning grooves 17 and 18 are formed in such a shape that the positioning protrusions 15 and 16 can be fitted exactly when the receptacle connector 5 and the plug connector 13 are properly fitted. is there.

[Effect of device]

 The connector of the present invention has the following effects. According to the connector of claim 1, when the receptacle connector 5 is slid obliquely to be fitted into the plug connector 13, the fitting protrusion 3 must be surely set on the fitting recess 11. Since 3 does not enter the fitting recess 11, it is possible to prevent the connector from being damaged by accidentally sticking and bending the pin contact 12 of the plug connector 13. According to the connector of claims 2 and 3, when the receptacle connector 5 is slid from the oblique direction to be fitted into the plug connector 13, or when it is fitted from above, the fitting direction is wrong. Then, since the receptacle connector 5 cannot be set at the fitting position of the plug connector 13, it is possible to prevent erroneous fitting. According to the connector of claim 4, even if the receptacle connector 5 and the plug connector 13 are fitted in the opposite directions, the positional relationship between the guide claw 20 and the guide groove 21 causes the connector 5 and the plug connector 13 to come into contact with each other. Since the mating direction is clearly visible, it is possible to check for incorrect mating between the receptacle connector 5 and the plug connector 13, which allows the mating work of both connectors 5 and 13 to be performed efficiently. You can
