In order to solve this problem, not only does a large insertion force be required, but the contact often buckles when the male housing is inserted into the opening of the female housing. As a structure, for example, with respect to a receptacle housing (female housing) of a receptacle connector (female connector), a guide for guiding deformation of a plug contact provided in a plug housing (male housing) of the plug connector (male connector) Fittings for receptacle connectors and plug connectors Continued time in the structure to the buckling deformation can be prevented when the plug contact and the receptacle contact and is different from the direction to the insertion direction to start contact is the contact contact each other things (see Patent Document 1).

Patent No. 2911860 (6th page, FIG. 10 and FIG. 11)

  In the case of the connector according to Patent Document 1 described above, a guide portion that guides deformation of the plug contact is provided in the receptacle housing, and the direction in which each contact in the receptacle connector and the plug connector starts to contact is different from the insertion direction. Although it is structured to prevent buckling deformation to some extent when the contacts come into contact with each other at the time of connection, the plug contact is in a structure that directly contacts the receptacle housing. There is a structural problem that buckling deformation is difficult to prevent sufficiently, the insertion force cannot be reduced, and the contact buckling deformation cannot be stably prevented after repeated use over a long period of time.

  The present invention has been made to solve such problems, and its technical problem is to reduce the insertion force at the time of mating and connection, and to prevent buckling deformation of the contact even when used repeatedly for a long time. It is an object of the present invention to provide a connector having a structure that can be stably prevented.

  According to the present invention, the female connector formed by holding the first contact having the first contact portion in the female housing, and the second contact having the second contact portion held in the male housing. In the connector having a structure that can be inserted and removed from each other, the female connector is formed from the inner wall so as to follow the insertion direction in order to insert the male housing in the female housing. The male connector has an opening formed by opening the front side, and an inner wall surface in the opening portion forms a slide guide surface that forms a step in the insertion direction. The male connector is an outer wall surface in the male housing. The connector which comprises the slide insertion surface which makes a level | step difference in the insertion direction and is connected is obtained.

  Further, according to the present invention, in the above connector, the slide guide surface of the female connector is located on one inner wall surface facing in the height direction of the female housing perpendicular to the insertion direction as a distance in the insertion direction. The first distance portion and the second distance portion on the other inner wall surface serve as a first slide guide surface, and a step from the first distance portion on the one inner wall surface And a third distance portion extending to the insertion direction and connected to the inner wall, and the second distance portion on the other inner wall surface. A fourth distance portion extending from the vertical direction to the position that extends in the insertion direction and intersects with the inner wall of the back is defined as a second slide guide surface. The slide guide surface is inserted as a distance in the insertion direction. The first distance insertion portion on one outer wall surface facing the vertical direction of the male housing perpendicular to the direction and the fifth distance portion on the other outer wall surface are designated as the first slide insertion surface. And one outer wall extending surface extending in the insertion direction and protruding in the insertion direction so as to form a step from the first distance portion on the one outer wall surface, and the other The other outer wall extending surface that is recessed in the height direction and extends in the insertion direction so as to form a step from the fifth distance portion on the outer wall surface is used as a second slide insertion surface. The male housing of the connector is inserted into the opening in the female housing of the female connector according to the insertion direction, and the first slide insertion surface is slid from the first slide guide surface to the second slide guide surface. When guided, the first slide insertion surface One outer wall surface of the first distance portion is in contact with one inner wall surface of the third distance portion on the second slide guide surface, and the fifth distance on the first slide insertion surface is The other outer wall surface of the portion is in contact with the other inner wall surface of the fourth distance portion in the second slide guide surface, and one outer wall extending surface and the other outer wall of the second slide insertion surface The extended surface is in contact with one inner wall surface of the first distance portion and the other inner wall surface of the second distance portion on the first slide insertion surface, respectively, so that the first contact portion And the connector which elastically deforms and contacts at least one of the 2nd contact parts is obtained.

  Further, according to the present invention, in the connector, in the second slide guide surface, one inner wall surface of the third distance portion, the other inner wall surface of the fourth distance portion, and the second slide insertion surface One outer wall extending surface and the other outer wall extending surface each have a connector including a stepped portion formed by a tapered inclined surface.

  In addition, according to the present invention, in the above connector, a connector is obtained in which the top of the step formed by the tapered inclined surface is rounded by chamfering.

  According to the present invention, in any one of the above connectors, the female connector is such that the first contact portion is juxtaposed on the other inner wall surface of the fourth distance portion of the second slide guide surface. The male connector is provided with a predetermined interval in a direction perpendicular to the insertion direction and the height direction with respect to the female housing, and the male connector has a second contact portion as a first slide insertion surface. A predetermined number of the fifth distance portions are arranged at a predetermined interval in a direction perpendicular to the insertion direction and the height direction with respect to the male housing so as to be arranged side by side toward the other outer wall surface side. A connector is obtained.

  In the case of the connector of the present invention, the basic structure of both the female housing in the female connector and the male housing in the male connector is improved, and the first contact of the first contact provided in the female housing by the slide conversion function is improved. One bent contact portion corresponding to either the contact portion or the second contact portion of the second contact provided in the male housing is hardly in contact with the top end of the other pin-shaped contact portion in the height direction. The body portion on the back side is elastically deformed by being pressed and contacted in two stages, or the first contact portion of the first contact provided in the female housing and the second contact portion provided in the male housing. Since one bent contact portion corresponding to any of the second contact portions of the contact and the other bent contact portion are pressed and contacted with each other in two stages, they are elastically deformed. The insertion force in the first contact portion is reduced, and the first contact portion of the first contact and the second contact portion of the second contact are stably pressed and contacted with a small amount of deformation due to a small load. As a result, it is possible to stably prevent buckling deformation at the contact portion of the contact even after repeated use for a long period of time. Needless to say, such an effect is obtained by setting a predetermined number of female contacts (first contacts) and male contacts (second contacts) to the female housing and the male housing, respectively, perpendicular to the insertion direction and the height direction. In the case of fitting and connecting so-called multi-core female connectors and male connectors arranged at predetermined intervals in any direction, the same can be obtained.

  A connector according to the best mode of the present invention includes a female connector formed by holding a first contact having a first contact portion in a female housing, and a second contact having a second contact portion as a male type. The male connector is constructed of a male connector that is held in a housing and has a structure that can be inserted and removed from each other. For the female connector, in the insertion direction for inserting the male housing in the female housing. It has an opening formed by opening the front side from the inner wall along the back, and the inner wall surface in this opening forms a slide guide surface that forms a step in the insertion direction. The outer wall surface of the male housing forms a slide insertion surface that is connected in a stepped manner in the insertion direction.

  Explaining the detailed structure, the slide guide surface in the female connector is located on one inner wall surface facing in the height direction of the female housing perpendicular to the insertion direction as the distance in the insertion direction in the female housing. The first distance portion and the second distance portion on the other inner wall surface are used as the first slide guide surface, and the inclined surface is tapered from the first distance portion on the one inner wall surface. Projecting in a tall direction so as to form a step, and extending from the third distance portion to the position extending in the insertion direction and connected to the inner wall, and tapered from the second distance portion on the other inner wall surface The second slide guide surface is a fourth distance portion that is recessed in the height direction so as to form a step by the inclined surface and extends to the insertion direction and intersects the inner wall perpendicularly.

  Further, the slide insertion surface in the male connector is a first distance portion on one outer wall surface facing the height direction of the male housing perpendicular to the insertion direction as a distance in the insertion direction in the male housing. The fifth distance portion on the other outer wall surface is used as the first slide insertion surface, and a step is formed by the tapered inclined surface from the first distance portion on the one outer wall surface. The outer wall extends in the insertion direction and protrudes in the height direction, and the height direction so that a step is formed by the tapered inclined surface from the fifth distance portion on the other outer wall surface. The other outer wall extending surface that is recessed and extends in the insertion direction is used as the second slide insertion surface.

  However, in the case of this connector, the male housing of the male connector is inserted into the opening of the female housing of the female connector according to the insertion direction, and the first slide insertion surface extends from the first slide guide surface to the second slide. When guided by being slide-converted to the guide surface, one outer wall surface of the first distance portion on the first slide insertion surface contacts one inner wall surface of the third distance portion on the second slide guide surface. And the other outer wall surface of the fifth distance portion on the first slide insertion surface is in contact with the other inner wall surface of the fourth distance portion on the second slide guide surface, and the second slide insertion surface One outer wall extending surface and the other outer wall extending surface of the first contact portion are brought into contact with one inner wall surface of the first distance portion and the other inner wall surface of the second distance portion on the first slide insertion surface, respectively. thing More comes to have a so-called slide transformation structure in which at least one of the first contact portion and second contact portion are in contact with the elastic deformation.

  In the case of the connector having this slide conversion structure, one inner wall surface of the third distance portion on the second slide guide surface, the other inner wall surface of the fourth distance portion, and the second slide insertion surface In addition to including a portion in which one outer wall extending surface and the other outer wall extending surface are stepped by a tapered inclined surface, in the female connector, the first contact portion is the second contact surface on the second slide guide surface. A predetermined number of the four distance portions arranged in parallel with the other inner wall surface are arranged at predetermined intervals in the direction perpendicular to the insertion direction and the height direction with respect to the female housing. In the connector, a predetermined number of the second contact portions are arranged in parallel to the male housing so that the second contact portions are arranged side by side toward the other outer wall surface side of the fifth distance portion in the first slide insertion surface. In a direction perpendicular to the height direction Those formed by deploying at intervals. Furthermore, the top of the step formed by the tapered inclined surface may be rounded by chamfering (R processing).

  Therefore, in such a connector, the male housing of the male connector is inserted into the opening in the female housing of the female connector along the insertion direction, and the first number of first contacts in the predetermined number of contacts included in the female connector is provided. When the second contact portions of the predetermined number of second contacts provided in the male connector are brought into contact with and connected to the contact portions, the first contact of the first contact provided in the female housing by the slide conversion function is provided. One bent contact portion corresponding to either the first contact portion or the second contact portion of the second contact provided in the male housing is almost at the top end in the height direction of the other pin-shaped contact portion. A structure in which the main body portion on the back side is pressed and contacted in two stages without being contacted and elastically deformed, or the first contact of the first contact provided in the female housing similarly. One bent contact portion corresponding to either the contact portion or the second contact portion of the second contact provided in the male housing, and the other bent contact portion are pressed into contact with each other in two stages and elastically deformed. Due to the structure, the insertion force at the time of fitting connection is reduced, and the first contact portion of the first contact and the second contact portion of the second contact are each less deformed by a small load. Press contact is stable in quantity. Therefore, each buckling deformation in the contact portion of each contact can be prevented.

  On the other hand, with respect to the plug connector 2, similarly, referring to FIG. 1A, the outer wall surface of the plug housing 6 which is a male housing is formed as a slide insertion surface forming a step in the insertion direction.

  More specifically, the slide insertion surface in the plug housing 6 which is a male housing has a distance in the insertion direction (similarly indicated by a white arrow) and is opposed to the one in the height direction perpendicular to the insertion direction. The first distance x1 portion on the outer wall surface and the fifth distance x5 portion on the other outer wall surface are shorter than the fourth distance x4 and the relationship x4> x5 is established. One of the slide insertion surfaces 6a and 6b, and one protruding from the height direction so as to form a step by a tapered inclined surface from the first distance x1 portion on one outer wall surface and extending in the insertion direction And the other outer wall extending in the insertion direction while being recessed in the height direction so as to form a step from the fifth distance x5 portion on the other outer wall surface by the tapered inclined surface. The surface is the second slide insertion surface 6c, 6c ' 6d, it is an 6d '.

  In the receptacle connector 1 and the plug connector 2, when the plug housing 6 of the plug connector 2 is slid into the opening 5 in the receptacle housing 3 of the receptacle connector 1 according to the insertion direction, it is shown in FIG. ), The first slide insertion surfaces 6a and 6b of the plug connector 2 are guided by the first slide guide surfaces 3a and 3b of the receptacle connector 1, but the plug connector 2 is further opened. In the middle stage of initial connection insertion pushed into the inner part 5, the tip of the first slide insertion surface 6 a of the plug connector 2 (the tip of the slide insertion surface 6 b is tapered as shown in FIG. 1C). (This is not a problem in operation because it is recessed from the tip of the slide insertion surface 6a) The second slide insertion surface 6d ′, which is a tapered inclined surface in the middle, reaches the position of the tapered inclined surface of the second slide guide surfaces 3c ′, 3d ′ in the receptacle connector 1 and is tapered. The second slide insertion surface 6 c ′, which is an inclined surface, reaches the inlet end surface of the opening 5 in the receptacle connector 1.

  At this time, the first slide insertion surfaces 6a and 6b of the plug connector 2 are guided by the first slide guide surfaces 3a and 3b, so that the second slide guide surface 3c of the tapered inclined surface of the receptacle connector 1 is obtained. It is shown that the transition to the guidance by ', 3d' is made, but after the guidance by the second slide guide surfaces 3c ', 3d', it comes into contact with the second slide guide surfaces 3c, 3d of the flat surface and The slide portion is converted and guided so that the second slide insertion surfaces 6c and 6d come into contact with the first slide guide surfaces 3a and 3b. At this time, the bent contact portion 7a of the plug-type contact 7 is caused by a small load. The receptacle connector 1 and the receptacle-type contact 4 are brought into contact with the pin-like contact portion 4a of the receptacle-type contact 4 with a small amount of deformation and further pushed in slightly. The fitting state of the plug connector 2.

It is pressed and held on each pin-like contact portion 4a provided on the surface 3d).

  In the case of the slide conversion structure here, in particular, when the connection initial insertion intermediate stage shown in FIG. 1C is compared with that of the known structure, in the known structure, each bent contact portion is in the height direction of each pin-like contact portion. Since it is elastically deformed in contact with the top part, a considerable insertion force is required at the time of mating connection, and each bent contact part receives a considerable load and comes into contact with each pin-shaped contact part with a considerable amount of deformation. In the structure according to the first embodiment having a slide conversion function, each bent contact portion 7a has a pin-like shape. The contact portion 4a has a structure in which it is almost in contact with the main body portion on the back side with little contact with the top end portion in the height direction of the contact portion 4a, and further in the fitted state in the connection late insertion completion stage shown in FIG. 1 (d). At the time of mating connection because of the two-stage pressing structure that presses and contacts the main body In addition to reducing the insertion force, each bent contact portion 7a is stably brought into contact with each pin-shaped contact portion 4a with a small amount of deformation due to a small load, so that the buckled deformation of each bent contact portion 7a is reduced. It can be seen that the structure can be sufficiently prevented.

  In the case of the connector according to the first embodiment, the second slide guide surfaces 3c 'and 3d' and the second slide insertion surfaces 6c 'and 6d' in the receptacle connector 1 and the plug connector 2 are all tapered at the same angle. However, the shape of these parts is not limited as long as the slide conversion structure can be obtained by forming a step, and other effects such as a concave curved surface can be obtained. In addition, it is preferable that the top of the step is rounded by rounding to make smooth conversion.

  In the case of the connector according to the first embodiment, the receptacle housing 3 of the receptacle connector 1 is provided with a predetermined number of receptacle-type contacts 4 having pin-like contact portions 4a, and the plug housing 6 of the plug connector 2 is bent. The structure in which the predetermined number of plug-type contacts 7 having the contact portions 7a are provided has been described. However, the form of the contact portions of the connectors in these connectors is not limited to the structure described in the first embodiment, and is arbitrarily set. It is possible to deform.
