  In Patent Document 1, the opposing surfaces of the inclined step portion of the socket contact and the inclined step portion of the header contact are inclined in a direction (fitting direction) in which the contacts can come out (FIG. 8 in Patent Document 1). Therefore, it is considered that the header contact can be pulled out from the socket contact with a low pulling force. Therefore, the header contact is easily detached from the socket contact.

  Therefore, an object of the present invention is to provide a connector that requires a high pulling force when one connector is released from the other connector.

An engagement step portion for engaging with the second bending portion is formed, and an inclination angle formed between a bottom surface and a side surface of the one engagement step portion is a right angle, and the other engagement step portion The inclination angle formed between the bottom surface and the side surface is obtuse.

  According to the present invention, at the contact portion between the first curved portion and the second curved portion, the engagement step portion having a right inclination angle and the engagement step portion having an obtuse angle are combined. Thus, when the first bending portion is released from the second bending portion, a high pulling force can be required for pulling out the first bending portion while suppressing deformation of both engagement step portions.

  Moreover, in this invention, it is preferable that the said 2nd bending part is supported by the said 2nd housing from the outer side in the top part. According to this, when the second contact is soldered to the substrate, the top of the second curved portion and the substrate are insulated by the second housing, so that the degree of freedom in designing the wiring pattern can be increased.

The portions that are in contact with each other are formed so as to be flat surfaces having no unevenness. According to this, since the part which can contact the other outer side surface of the 1st bending part and the other inner side surface of the 2nd bending part becomes long in a fitting direction, effective fitting length can be lengthened. In the above configuration, when the first bending portion is fitted to the second bending portion, the other outer surface of the first bending portion and the other inner surface of the second bending portion are in contact with each other. Since it does not engage, it can suppress that a 2nd contact moves to a fitting direction at the time of the fitting cancellation | release from the 2nd bending part of a 1st bending part.

  Further, in the present invention, during the fitting operation, the other outer surface of the first bending portion and the other inner surface of the second bending portion are the one outer side of the first bending portion. Prior to contact with the side surface and the one inner surface of the second bending portion. According to this, after the contact portion between the other outer surface of the first bending portion and the other inner surface of the second bending portion is displaced, one outer surface of the first bending portion and one of the second bending portions are Since the inner surface is engaged, the first bending portion can be fitted to the second bending portion with a low insertion force. Therefore, a low insertion force can be realized during the fitting operation of the first bending portion to the second bending portion, and a high pulling force can be obtained during the fitting releasing operation of the first bending portion from the second bending portion. Since it can be realized, both a low insertion force and a high pulling force can be achieved.

  According to the connector of the present invention, in the contact portion where the first bending portion and the second bending portion are in contact with each other during the fitting operation of the first bending portion to the second bending portion, the engagement step portion having a right angle of inclination By making the engagement combined with the engaging step portion whose inclination angle is an obtuse angle, while suppressing the fitting of the first bending portion from the second bending portion, while suppressing deformation of both engagement step portions, A high pulling force can be required for pulling out the first curved portion.

  Next, with reference to FIG. 4, a description will be given of when the plug connector 10 is fitted to and released from the receptacle connector 20.

  FIG. 4A shows a state when the plug connector 10 is inserted into the receptacle connector 20 (at the time of fitting operation). FIG. 4 (b) shows a state when the plug connector is fitted to the receptacle connector (when fitted). FIG. 4C shows a state when the plug connector is pulled out from the receptacle connector (when the fitting is released).

  As shown in FIGS. 4A to 4C, the plug bending portion 12b is curved so as to protrude toward the receptacle connector 20, and is supported by the side walls 15a and 15b of the plug housing from the inside thereof. Yes. The receptacle bending portion 22 d is curved so as to open toward the plug connector 10.

  The plug bending portion 12 b has a top portion 31 and two side portions 32 and 33 located on opposite sides of the top portion 31. The two side parts 32 and 33 are opposed to the direction orthogonal to the fitting direction. Further, the receptacle bending portion 22d includes a top portion 41, two side portions 42 and 43 positioned on opposite sides of the top portion 41, and a bent portion 44 bent in a substantially square shape from the tip of the side portion 43. have. The two side parts 42 and 43 are opposed to the direction orthogonal to the fitting direction.

  As shown in FIGS. 4A and 4B, during the fitting operation of the plug bending portion 12b to the receptacle bending portion 22d, the outer surface 33a of the side portion 33 of the plug bending portion 12b and the bending of the receptacle bending portion 22d. The inner side surface 44a of the portion 44 contacts the outer side surface 32a of the side portion 32 of the plug bending portion 12b and the inner side surface 42a of the side portion 42 of the receptacle bending portion 22d. Further, during the fitting operation, the outer side surface 33a of the side portion 33 of the plug bending portion 12b also contacts the inner side surface 43a of the side portion 43 of the receptacle bending portion 22d. Therefore, during the fitting operation of the plug bending portion 12b to the receptacle bending portion 22d, the plug bending portion 12b and the receptacle bending portion 22d come into contact at two places. The outer side surfaces 32a and 33a are orthogonal to the fitting direction and are directed in opposite directions. Similarly, the inner side surfaces 42a and 44a are orthogonal to the fitting direction and are directed in opposite directions.

  Next, two contact portions where the plug bending portion 12b and the receptacle bending portion 22d come into contact with each other when the plug bending portion 12b is fitted to the receptacle bending portion 22d (during the fitting operation) will be described.

  First, one of the two contact portions and the periphery thereof (S1 shown in FIG. 4B) will be described. Here, for convenience of explanation, description will be made with reference to an enlarged view of FIG.

  A concave portion 32 b extending in the longitudinal direction of the side portion 32 is formed on the outer side surface 32 a. The recess 32b is formed by crushing the outer surface 32a in the thickness direction of the plug contact 12. Further, the inner side surface 42 a is formed with a recess 42 b extending in the longitudinal direction of the side portion 42. The recess 42b is formed by crushing the inner side surface 42a in the thickness direction of the receptacle contact 22.

  As shown in FIG. 4C, in this embodiment, when the plug bending portion 12b is released from the receptacle bending portion 22d, the lower end of the concave portion 32b and the upper end of the concave portion 42b are engaged with each other. The bending portion 12b engages with the receptacle bending portion 22d. Therefore, in the following, the lower end of the recess 32b of the plug bending portion 12b is referred to as a plug engagement step portion P, and the upper end of the recess 42b of the receptacle bending portion 22d is referred to as a receptacle engagement step portion R.

  In the plug engagement step portion P, the inclination angle formed between the bottom surface 32q of the recess 32b and the lower side surface 32p is an obtuse angle. Further, in the receptacle engagement step R, the inclination angle formed between the bottom surface 42q of the recess 42b and the upper side surface 42r is a right angle.

  When the plug engagement step portion P and the receptacle engagement step portion R are engaged, it is difficult to release the fitting of the plug bending portion 12b from the receptacle bending portion 22d. In the plug engagement step portion P, when the inclination angle formed by the bottom surface 32q and the lower side surface 32p of the recess 32b is a right angle, the inclination angle of the plug engagement step portion P and the inclination angle of the receptacle engagement step portion R. Since the plug engagement step portion P and the receptacle engagement step portion R are easily cut and deformed when the plug bending portion 12b is released from the receptacle bending portion 22d. In the present embodiment, since the plug engagement step portion P has an obtuse inclination angle and the receptacle engagement step portion R has a right inclination angle, the plug engagement step portion P and the receptacle engagement step portion R are securely connected. The plug engagement step portion P and the receptacle engagement step portion R are not easily deformed because the plug engagement step portion P is inclined while being engaged. Further, when the plug engagement step portion P and the receptacle engagement step portion R are engaged, the plug bending portion 12b and the receptacle bending portion 22d are in contact with each other, so that the plug bending portion 12b and the receptacle bending portion are in contact with each other. Conduction with 22d becomes possible.

  Next, the other contact portion of the two contact portions and the periphery thereof (S2 shown in FIG. 4B) will be described. Here, a description will be given with reference to FIG.

  As shown in FIG. 4B, the outer side surface 33a, the inner side surface 43a, and the inner side surface 44a are flat surfaces without irregularities. Therefore, during the fitting operation, the entire outer surface 33a can come into contact with at least one of the inner side surface 43a and the inner side surface 44a. When the outer side surface 33a comes into contact with at least one of the inner side surface 43a and the inner side surface 44a, the plug bending portion 12b and the receptacle bending portion 22d can be electrically connected.

  In the present embodiment, as shown in FIGS. 4A and 4B, when the plug connector 10 is fitted to the receptacle connector 20, the outer surface 33a of the plug bending portion 12b and the inner surface of the receptacle bending portion 22d. After contact with 44a and the bent portion 44 is displaced, the outer side surface 32a of the plug bending portion 12b and the inner side surface 42a of the receptacle bending portion 22d come into contact with each other. In other words, during the fitting operation of the plug bending portion 12b to the receptacle bending portion 22d, prior to the contact between the outer side surface 32a of the plug bending portion 12b and the inner side surface 42a of the receptacle bending portion 22d, the outer side of the plug bending portion 12b is removed. The side surface 33a and the inner side surface 44a of the receptacle bending portion 22d come into contact with each other, and the bent portion 44 is displaced.

  Next, the structure of the receptacle connector 20 will be described with reference to FIGS.

  As shown in FIG. 3B, the bottom wall 26 of the receptacle housing 21 is connected to each of the side walls 25a and 25b, and the top 41 of the receptacle bending portion 22d is disposed toward the convex portion 27. Extends to position. Therefore, when the receptacle contact 22 is mounted on the receptacle housing 21, the bottom wall 26 exists below the top 41, so that the receptacle curved portion 22d is located on the top 41 from the outside (the lower side in FIG. 3B) from the bottom. Supported by a wall 26. Therefore, when the receptacle connector 20 is soldered to a substrate (not shown), the bottom wall 26 is interposed between the substrate and the top portion 41 of the receptacle contact 22, so that the top portion 41 and the substrate are insulated.

  As shown in FIGS. 3A and 3B, a plurality of holding walls 50a and 50b are provided on the outer surfaces of the side walls 25a and 25b. The holding walls 50a and 50b have a rectangular shape, and are provided along the height direction (fitting direction) of the side walls 25a and 25b in portions where the grooves 29 of the side walls 25a and 25b are not formed. As shown in FIG. 3A, the width of the holding walls 50 a and 50 b is larger than the interval between the two adjacent grooves 29. Therefore, the entrance into which the holding portion 22b of the groove 29 is fitted is narrow. (See FIGS. 5 and 6).

  FIG. 5 shows the receptacle housing 21, and FIG. 6 shows the case where the receptacle contact 22 is attached to the receptacle housing 21. As shown in FIG. 5A, the inlet 29 a into which the holding portion 22 b of the groove 29 is fitted is narrower than the width of the other portion of the groove 29 by the holding walls 50 a and 50 b. As shown in FIG. 6 (enlarged view), the interval between the two adjacent holding walls 50a and the interval between the two adjacent holding walls 50b are both in the width of the holding portion 22b (in the longitudinal direction of the receptacle contact 22). Smaller than the total length of the projection length of the two protrusions 25e. Therefore, since the holding wall 50b exists adjacent to the protruding portion 25e behind the protruding portion 25e (above the protruding portion 25e in FIG. 5), the protruding portion 25e and the holding portion 22b are held behind the holding wall 50b. Is supported by Therefore, the movement of the holding portion 22b in the thickness direction of the receptacle contact 22 (upward in FIG. 6) is restricted.

  Further, as shown in FIG. 5B, the holding wall 50 b extends in the height direction (fitting direction) of the receptacle housing 21. Although not shown, similarly, the holding wall 50a also extends in the height direction (fitting direction) of the receptacle housing 21.

  As described above, the plug contacts 12 are subjected to crushing processing in order to form the recesses 32b. The crushing process is performed on the straight strip-shaped conductive member before bending the strip-shaped conductive member. The plug contact 12 is obtained by bending the straight strip-shaped conductive member in which the concave portion 32b is formed by crushing at a plurality of different locations in the longitudinal direction. Similarly, when the receptacle contact 22 is formed, the strip-shaped conductive member formed into a straight line before bending the strip-shaped conductive member is subjected to crushing, and then the straight strip-shaped conductive member is moved in the longitudinal direction. Receptacle contact 22 is obtained by bending at a plurality of different locations.

  As described above, the connector according to the present embodiment has the following effects. When the plug bending portion 12b is disengaged from the receptacle bending portion 22d, the plug engaging step portion P having an obtuse angle and the receptacle engaging step portion Q having an inclined angle engage with each other. When the fitting of the first bending portion from the second bending portion is released, a high pulling force can be required to pull out the plug bending portion 12b while suppressing deformation of the plug engagement step portion P and the receptacle engagement step portion Q. .

  Further, the receptacle bending portion 22d is supported by the bottom wall 26 from the outside at the top portion 41 thereof. As a result, when the receptacle contact 22 is soldered to the substrate, the top 41 of the receptacle bending portion 22d and the substrate are insulated by the bottom wall 26, so the degree of freedom in designing the wiring pattern can be increased. Further, the deformation of the top 41 of the receptacle bending portion 22d can be suppressed during the fitting operation of the plug bending portion 12b to the receptacle bending portion 22d.

  Furthermore, since the holding walls 50a and 50b are provided behind the protruding portion 25e of the receptacle contact 22, the holding portion 22b and the protruding portion 25e are held from behind by the holding walls 50a and 50b. Accordingly, movement of the holding portion 22b in the thickness direction of the receptacle contact 22 is restricted. Therefore, stable holding of the receptacle contact 22 can be achieved.

  In addition, the outer side surface 33a and the inner side surfaces 43a and 44a that are in contact with the plug bending portion 12b during the fitting operation to the receptacle bending portion 22d are formed so as to have a flat surface without unevenness. The effective fitting length can be increased. Further, since the outer side surface 33a and the inner side surfaces 43a and 44a are not engaged, the receptacle contact 22 moves in the fitting direction when the plug bending portion 12b is released from the receptacle bending portion 22d (when pulled out). Can be suppressed.

  Further, during the fitting operation (insertion) of the plug bending portion 12b to the receptacle bending portion 22d, the plug bending is performed prior to the contact between the outer side surface 32a of the plug bending portion 12b and the inner side surface 42a of the receptacle bending portion 22d. Since the outer surface 33a of the portion 12b and the inner side surface 44a of the receptacle bending portion 22d are in contact with each other, the outer surface 32a and the inner side surface 42a are in contact after the bent portion 44 is displaced. Therefore, the plug bending portion 12b can be fitted to the receptacle bending portion 22d with a low insertion force. Therefore, a low insertion force can be realized during the fitting operation of the plug bending portion 12b to the receptacle bending portion 22d, and a high pulling force can be realized when the plug bending portion 12b is released from the receptacle bending portion 22d. Therefore, both a low insertion force and a high pulling force can be achieved.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims. For example, in the present embodiment, in the plug engagement step portion P and the receptacle engagement step portion R, the inclination angle formed by the bottom surface 32q and the lower side surface 32p of the plug engagement step portion P is an obtuse angle, and the receptacle engagement step The inclination angle formed between the bottom surface 42q of the step portion R and the upper side surface 42r is a right angle, but the inclination angle formed between the bottom surface 32q of the plug engagement step portion P and the lower side surface 32p is a right angle, and the receptacle engagement step. The inclination angle formed between the bottom surface 42q of the portion R and the upper side surface 42r may be an obtuse angle. The same effects as those of the present application can be obtained by the above configuration.

  In the present embodiment, the receptacle housing 21 has the holding walls 50a and 50b, but may not have the holding walls 50a and 50b. Further, the bottom wall 26 of the receptacle housing 21 may not extend toward the convex portion 27 to a position where the top portion 41 of the receptacle connector 20 exists.

  In the present embodiment, the outer surface 33a of the side portion 33 of the plug bending portion 12b, the inner side surface 44a of the bending portion 44 of the receptacle bending portion 22d, and the inner side surface 43a of the side portion 43 are both flat surfaces having no unevenness. However, at the time of fitting operation of the plug bending portion 12b to the receptacle bending portion 22d, at least in a portion where they are in contact with each other, if they are formed to be flat surfaces without unevenness, the portions that are not in contact with each other are It may not be a flat surface. Furthermore, in this embodiment, the outer side surface 33a of the plug bending portion 12b and the inner side surfaces 43a and 44a of the receptacle bending portion 22d are both flat surfaces without irregularities, but the outer side surface 33a and the inner side surfaces 43a and 44a are not flat. A recess may be formed in at least one of them.
