Description

  The present invention relates to a male and female connector provided with a socket and a plug inserted into the socket.

  2. Description of the Related Art Conventionally, a socket for a male / female connector has a socket body in which a horizontally long plug insertion hole is formed in a front view, and four plug holding springs respectively disposed on four inner surfaces of the plug insertion hole. (For example, refer to Patent Document 1). Moreover, the plug of this male-female connector has a horizontally long rectangular fitting part inserted into the plug insertion hole and four locking recesses formed on the four outer surfaces of the fitting part, respectively. . When the plug is inserted into the socket, each plug holding spring engages with the corresponding locking recess, and the plug is fixed to the socket.

  Further, Patent Document 1 describes the spring load of the plug holding spring and the shape of the locking recess so that the plug is pulled out of the socket when the plug is pulled strongly in the axial direction or in a direction crossing the axial direction. The adjustment is described.

JP 2012-9375 A

  However, in the conventional male / female connector, the plug is fixed to the socket by inserting the oblong fitting portion into the oblong plug insertion hole and engaging the plug holding spring and the locking recess. Therefore, for example, when the plug is twisted in the lateral direction, there is a risk that one of the tips of the fitting portion will be strongly abutted against the inner surface of the plug insertion hole and damaged. In order to prevent the interference between the fitting portion and the plug insertion hole, a large space for deforming the plug holding spring in the horizontal direction or the vertical direction is required, and the socket becomes large.

  Accordingly, an object of the present invention is to rationally configure a male and female connector capable of preventing damage even when the plug is twisted while achieving downsizing.

  The male / female connector according to the present invention includes a socket having a first body in which a hole is formed, and a plug having a second body including an insertion portion to be inserted into the hole. At least a pair of inner walls facing each other has a first inclined surface that is a taper inward from the opening of the hole portion along the insertion direction of the insertion portion, and the first inclined surface is A holding portion that holds the insertion portion; and the insertion portion has a second inclined surface that is parallel to the first inclined surface in the inserted state, and the second inclined surface is the holding portion. And at least one of the holding portion and the engaged portion is elastically deformable.

  According to this configuration, the holding portion that holds the insertion portion or the engaged portion that engages with the holding portion is elastically deformed. Therefore, when the plug is inserted into the socket, the holding portion or the engaged portion is restored after the deformation. Then, the holding portion engages with the engaged portion, and the plug is fixed to the socket. At this time, the first inclined surface is formed on the pair of inner walls opposed to the hole portion of the socket, and the second inclined surface parallel to the first inclined surface is formed at the insertion portion of the plug. It can be inserted smoothly.

  Further, in this configuration, a first inclined surface that is a taper inward in the plug insertion direction, that is, a first inclined surface that extends in the plug removal direction is formed in the socket hole, and is parallel to the first inclined surface. The second inclined surface is a taper inward in the insertion direction. As a result, for example, when the plug is strongly twisted in the lateral direction, one end of the narrowest second inclined surface moves to the expansion space of the first inclined surface as it retreats while inclining. For this reason, it is possible to remove the plug from the socket while smoothly elastically deforming the holding portion or the engaged portion without causing the tip of the second inclined surface to strongly contact the first inclined surface. Therefore, damage to the plug or socket can be prevented.

  In addition, since the plug is removed from the socket by utilizing the expansion space of the first inclined surface, the deformation amount of the holding portion or the engaged portion is small. In addition, since the holding portion for holding the insertion portion is provided on the first inclined surface, the accommodation space for the plug holding spring is not required as in the prior art. Therefore, the male and female connectors can be made compact. Thus, it was possible to rationally configure a male / female connector capable of preventing damage even when the plug was twisted while achieving downsizing.

  In another characteristic configuration, the first main body includes a resin housing and a metal shell covering the housing. The shell includes at least a part of the first inclined surface and the holding portion. Is the point that is formed.

  By providing a metal shell outside the housing as in this configuration, the EMI (electro-magnetic interference) characteristics of the connector can be improved. In addition, since the holding portion for holding the plug is formed in the shell, it is reasonable that a separate plug holding member is not required.

  In another characteristic configuration, the shell is formed of a single metal plate, and the first inclined surface extends from a base portion in a state where the first inclined surface is separated from the surroundings. It is in the point comprised with the metal member with which two inclined surfaces are mounted | worn.

  If the shell is formed of a single metal plate and extends from the base in a state where the first inclined surface is separated from the surroundings as in this configuration, the first inclined surface is desired while saving the number of parts. The elastic force can be set. Therefore, the plug can be easily inserted and removed, and when the plug is strongly twisted, the plug can be smoothly removed from the socket. Further, if the engaged portion is made of a metal member, it is difficult to wear even when the plug and socket are repeatedly inserted and removed, and the durability of the plug can be improved.

  Another characteristic configuration is that the maximum width of the shell and the maximum width of the insertion portion are the same.

  If the maximum width of the shell and the maximum width of the insertion portion are the same as in this configuration, the male and female connectors can be made compact compared to the conventional configuration in which the socket holding space for the plug holding spring is provided. Can do.

  In another characteristic configuration, the holding portion is configured by a hemispherical projection protruding inward of the first inclined surface, and the engaged portion is configured by a groove that engages with the projection. It is in.

  If the holding of the plug with respect to the socket is configured with a protrusion protruding inward of the first inclined surface and a groove engaging with the protrusion as in this configuration, the holding force can be easily adjusted. In addition, since the protrusion is formed in a hemispherical shape, for example, when the plug is strongly twisted in an oblique direction, the engagement between the protrusion and the groove is easily released, and the plug can be smoothly removed from the socket.

  Another characteristic configuration is that the first inclined surface is formed over the entire circumference of the inner wall of the hole.

  If the first inclined surface and the second inclined surface are formed on the top, bottom, left, and right of the socket and the plug as in this configuration, the plug can be smoothly removed from the socket even if the plug is twisted at any angle.

  Another characteristic configuration is that the holding portion is formed by joining another member to the first inclined surface.

  If the holding portion is formed of a member different from the first inclined surface as in this configuration, the holding force of the plug with respect to the socket can be easily adjusted.

It is a whole perspective view of a socket. It is the whole plug perspective view. It is the disassembled perspective view seen from the plug insertion side of the socket. It is the disassembled perspective view seen from the back side of the socket. It is the disassembled perspective view seen from the socket insertion side of a plug. It is the disassembled perspective view seen from the back side of the plug. It is sectional drawing which shows the state which mounted | wore the plug with the socket. It is sectional drawing which shows the state which the tensile force of the axial direction acted on the plug. It is sectional drawing which shows the state by which the plug was twisted.

Then, the second main body 6 having the second contact 5 and the metal member 65 is inserted from the socket insertion side of the main body cover 7. At this time, as shown in FIG. 7, the protruding portion 62 a of the second main body 6 gets over the inner surface convex portion 72 a of the main body cover 7. Further, the rectangular portion 81 of the cable cover 8 is sandwiched between the extended portion 64 c of the second main body 6 and the back surface portion 71 of the main body cover 7. In this state, the projecting portion 62a abuts on the inner surface convex portion 72a and the movement of the second main body 6 to the socket insertion side with respect to the main body cover 7 is prevented, so the second main body 6, the main body cover 7 and the cable cover 8 are prevented. Are integrated.

5. Connection of Socket and Plug FIG. 7 shows a state where the assembled socket 1 and plug 2 are connected. As described above, the first side inclined surfaces 43a and 47c and the first up and down inclined surface 47b are formed on the socket 1, and the second side inclined surfaces 61c and 65c and the second up and down inclined surfaces 61b and 51a are formed on the plug 2. Therefore, the plug 2 can be inserted into the socket 1 smoothly. Further, the holding portions 43b of the pair of separation portions 43 are engaged with the engaged portions 65d of the pair of metal members 65 while elastically deforming, and the socket 1 and the plug 2 are fixed. As a result, when a tensile force acts in the axial direction of the plug 2, the pair of holding portions 43 b interfere with the pair of metal members 65. That is, since the insertion portion 61 is held between the pair of holding portions 43b, the plug 2 does not easily come out even if an unintended small tensile force is applied. On the other hand, as shown in FIG. 8, when the plug 2 is pulled strongly in the axial direction, the holding portion 43 b gets over the metal member 65 while being elastically deformed, so that the plug 2 can be smoothly removed from the socket 1.

  As shown in FIG. 9, when the plug 2 is strongly twisted in the lateral direction, one end of the narrowest body side inclined surface 61 c of the insertion portion 61 of the plug 2 is retracted while being inclined. Along with this, the hole 40 of the first main body 4 moves to the expansion space of the shell side inclined surface 43a whose width gradually increases in the retraction direction. That is, the phenomenon in which one of the tips of the main body side inclined surface 61c strongly contacts the shell side inclined surface 43a is alleviated. As a result, even if a large twisting force acts on the plug 2, the socket 1 and the plug 2 are not damaged. Moreover, the amount of interference that one of the pair of holding portions 43b tries to get over one of the pair of metal members 65 is the axial direction in which the pair of holding portions 43b shown in FIG. Therefore, the plug 2 can be easily removed from the socket 1. In addition, as described above, the socket 1 and the plug 2 are provided with the first vertical inclined surface 47b and the second vertical inclined surfaces 61b and 51a, so that even when the plug 2 is twisted in any direction, the plug 2 can be It can be smoothly removed from the socket 1. Moreover, since the holding portion 43b formed on the shell side inclined surface 43a of the first main body 4 is formed of a hemispherical protrusion, the holding portion 43b moves in the twisting direction with respect to the engaged portion 65d. It is easy to remove the plug 2 more smoothly.
