  The present invention belongs to the technical field of electrical connectors, and relates to an electrical connector housing and an electrical connector provided with such a housing.

  Patent Document 1 discloses an electrical connector having two or more flag-type terminals and a housing thereof. The electrical connector includes an integrated housing and two or more receptacle contacts. The integrated housing includes a housing having substantially the same shape, and is connected by forming a slot between opposing side walls. A common cover is formed on one end edge of these housings via a hinge. A latch member is formed in both the outer surface and the slot of the housing, and a corresponding latch member is formed on the inner surface of the common cover. The plurality of flag-type terminals are inserted into the cavities of the housings, and are held in the housings by closing and latching the common cover.

  In the case of the insulating cover for terminals disclosed in Patent Document 4 and Patent Document 5, it is difficult to realize a double pole that accommodates two or more terminals. Polarization can be realized. However, for example, in the case of the housing of the electrical connector of Patent Document 1, the flag-type terminal receives a force from the counterpart terminal when the electrical connector using the housing is fitted to the counterpart electrical connector. Such an external force in the anti-fitting direction is received by the common cover. Users of this type of electrical connector are required to increase the strength of the electrical connector housing against such external forces.

  Therefore, the present inventor provides the housing with a lance as disclosed in Patent Document 6 and locks the lance to a terminal where a conductor such as an electric wire extends in a direction crossing the fitting direction. An attempt was made to propose a housing having strength against an external force in the anti-fitting direction with a solution different from the housing of the electrical connector of Patent Document 1. However, since the conductor extends from the terminal in a direction crossing the fitting direction, if the lance is provided so as not to interfere with the conductor or the connection portion of the terminal with the conductor, the lance is moved outward. In some cases, the housing has to be arranged, and the housing is enlarged.

The present invention has been made paying attention to such points, and the object of the present invention is to provide a lance extending in a direction opposite to the fitting direction of the terminal to be accommodated and of the wall of the housing body. The lance is formed by a part of the flat wall opposite to the side where the stepped portion of the terminal falls , so that the conductor extends in the direction crossing the fitting direction, and the counterfitting is performed. An object of the present invention is to provide an electrical connector housing and an electrical connector that can be provided with strength against external force in the opposite direction and can be made compact.

To achieve the above object, the first electrical connector housing of the present invention comprises:
A contact portion that comes into contact with the mating conductive member, and a connection that is provided on the side higher in the height direction than the contact portion and connects the terminal ends of the conductors introduced along the direction intersecting the height direction A housing for an electrical connector that accommodates a terminal provided with a stepped portion that falls in a direction intersecting the height direction when the height direction is advanced toward the higher side of the height direction,
A first storage chamber that extends in the height direction and has both ends in the height direction open to the outside, and a direction that intersects the height direction and communicates with a higher end of the first storage chamber A housing body provided so as to form a second storage chamber that extends to the outside and has a higher side in the height direction open to the outside,
It extends straight in the height direction and faces the first storage chamber, and has an end on the lower side in the height direction provided on the housing body, and a second end on the higher side in the height direction. 1 is provided with a locking portion protruding toward the storage chamber, and has an elastic lance,
The contact portion of the terminal is accommodated in the first accommodating chamber, the connecting portion of the terminal is accommodated in the second accommodating chamber, and the locking portion of the lance is hung on the stepped portion of the terminal. Is configured as
Of the walls of the housing body provided so as to form the first storage chamber on the inside, a wall opposite to the side where the stepped portion is formed is formed in a flat plate shape, and the lance is formed in the flat plate shape. forms a part of the wall,
The contact portion of the terminal and the lance are configured not to overlap each other in the first storage chamber when viewed from the direction perpendicular to the height direction and the direction in which the locking portion of the lance protrudes. ,
The electrical connector housing is configured such that an end face on a higher side in the height direction of the locking portion is inclined so as to go to the first storage chamber as it goes toward a lower side in the height direction .

  When the terminal, in which the conductor extends in a direction intersecting the fitting direction, is inserted into the housing along the height direction, the terminal is accommodated in the first accommodation chamber and the second accommodation chamber, and A conductor is accommodated in the second accommodation chamber. Meanwhile, the lance is elastically deformed and the locking portion locks the terminal. In this case, when an external force directed in the anti-fitting direction acts on the terminal, the external force is received by the lance, and thus the housing has strength against the external force directed in the anti-fitting direction. Further, since the lance extends from the lower side in the height direction to the higher side, the conductor or the conductor in the terminal is compared with the conventional lance extending from the higher side in the height direction to the lower side. Difficult to interfere with connecting parts. Therefore, the lance can be arranged close to the inside, and the lance forms a part of the flat plate-like wall, so that the housing can be made compact. Further, unlike the conventional common cover, it is possible not to provide a reinforcing member for receiving the terminal on the non-fitting side, and when such a reinforcing member is not provided, the housing in the fitting direction is not provided. The dimensions are shortened to achieve compactness, and the labor for assembling the reinforcing member to the housing can be saved.

Since the end surface on the higher side in the height direction of the locking portion is inclined so as to go to the first storage chamber toward the lower side in the height direction, the terminal is moved along the height direction. When the terminal is inserted into the housing, the terminal is guided by the end face on the higher side in the height direction and is led into the first storage chamber, and the locking portion is pushed to the outside of the first storage chamber. Therefore, the possibility that the terminal interferes with the lance is reduced.

The electrical connector housing extends from a portion corresponding to the locking portion to the higher side in the height direction .

  When the terminal, in which the conductor extends in a direction intersecting the fitting direction, is inserted into the housing along the height direction, the terminal is accommodated in the first accommodation chamber and the second accommodation chamber, and A conductor is accommodated in the second accommodation chamber. Meanwhile, the lance is elastically deformed and the locking portion locks the terminal. In this case, when an external force directed in the anti-fitting direction acts on the terminal, the external force is received by the lance, and thus the housing has strength against the external force directed in the anti-fitting direction. Further, since the lance extends from the lower side in the height direction to the higher side, the conductor or the conductor in the terminal is compared with the conventional lance extending from the higher side in the height direction to the lower side. Difficult to interfere with connecting parts. Therefore, the lance can be arranged close to the inside, and the lance forms a part of the flat plate-like wall, so that the housing can be made compact. Further, unlike the conventional common cover, it is possible not to provide a reinforcing member for receiving the terminal on the non-fitting side, and when such a reinforcing member is not provided, the housing in the fitting direction is not provided. The dimensions are shortened to achieve compactness, and the labor for assembling the reinforcing member to the housing can be saved.

The housing body is provided with a support portion, and the support portion is located on the opposite side of the lance from the first storage chamber side and is separated from the lance by an allowable amount. Since it extends from the portion corresponding to the locking portion to the higher side in the height direction, the support portion supports the elastically deformed lance, and over-deformation of the lance is prevented. In addition, when an external force is received near the lance from the outside of the housing body, the lance is prevented from being excessively deformed when the external force is received by the support portion.

The housing of the third electrical connector of the present invention is the housing of the first or second electrical connector,

However, this does not limit the shape of the housing body, and the housing body is formed, for example, in a columnar shape or a shape formed by combining two or more components having other shapes. May be. Each housing body 210 is provided so that a first storage chamber 211 and a second storage chamber 212 communicating with the first storage chamber 211 are formed therein. The first storage chamber 211 extends in the height direction, and both ends in the height direction are open to the outside. The counterpart conductive member is received from the lower end of the first storage chamber 211 in the height direction. When the contact portion of the terminal is, for example, a post, the contact portion may be brought out to a lower side in the height direction than the first storage chamber and contacted with the counterpart conductive member. The second storage chamber 212 communicates with the higher end of the first storage chamber 211 and extends in a direction intersecting the height direction, and the higher side in the height direction is open to the outside. . The direction intersecting with the height direction includes a direction orthogonal to the height direction. In the case of this embodiment, the second storage chamber 212 extends in the depth direction, the depth side of the second storage chamber 212 in the depth direction is closed by the wall of the housing body 210, and The near side in the depth direction of the second storage chamber 212 is open so that the conductor 300 can be introduced in a straight line without bending. However, the second storage chamber only needs to extend, for example, in the width direction or other direction intersecting the height direction, and both ends of the second storage chamber are open even if both are closed. May be. The direction in which the second storage chamber extends is preferably coincident with the direction in which the conductor extends from the terminal, but is not limited thereto. The housing main body 210 is open to the higher side in the height direction in the second storage chamber 212. However, as shown in FIGS. 12 and 13, the housing main body 210 has the second storage chamber 212 in the second storage chamber 212. A lid 214 may be provided on the higher side in the height direction, and the second storage chamber 212 may be closed by the lid 214. In this modification, one lid 214 is provided for the housing 200. For example, a lid is provided for each housing body, a lid is provided only for a part of the housing body, and the second of the housing body. There are many other variations, such as providing a lid that covers only a portion of the storage chamber.

The lance 220 has elasticity. In the case of this embodiment, the lance 220 is formed of the same synthetic resin as the housing main body 210, but may be formed of other materials as long as it has elasticity. Further, although the lance 220 is integrally provided with the housing main body 210 by integral molding, the lance may be assembled with the housing main body after being separately molded. The lance 220 is provided for each housing body 210. In the case of this embodiment, two lances 220 are provided for each housing body 210, but this is because two spring pieces 112 are provided on the contact portion 110 of the terminal 100, and each spring piece is provided. This is because the stepped portions 130 are formed in 112 respectively. However, these two lances may be provided in series for each housing body 210 or may be integrated, or only one of the lances may be provided. The lance 220 extends in the height direction and faces the first storage chamber 211. The lance 220 is provided so that the cross-sectional shape when cut along the surface facing the height direction has the same shape along the height direction except for a locking portion 221 described later. The cross-sectional shape may be changed, for example, by narrowing it toward the higher side in the height direction. The lance 220 extends straight in the height direction. However, when the lance 220 is slightly inclined with respect to the height direction, the lance 220 becomes a reference form. In the case of this embodiment, the lance 220 is arranged on one side in the width direction with respect to the first storage chamber 211, but the lance is provided at any part around the first storage chamber. Also good. The lower end of the lance 220 in the height direction is provided in the housing main body 210, whereby the lance 220 is provided in a cantilever shape. For example, as shown in FIGS. 2, 3, 8 to 10, the side of the wall of the housing main body 210 provided so as to form the first storage chamber 211 on the inner side is opposite to the side where the stepped portion falls. The side wall is formed in a flat plate shape, and the lance 220 forms a part of the flat plate wall. This is preferable for making the housing 200 compact, but it becomes a reference form when the lance is provided separately from the wall inside the wall. At the end of the lance 220 on the higher side in the height direction, a locking portion 221 that protrudes toward the first storage chamber is provided. In the case of this embodiment, the lower end surface 221a in the height direction of the locking portion 221 is orthogonal to the height direction, but the end surface may form an angle with the height direction. It suffices to cross the height direction. For example, as shown in FIG. 10, the contact portion 110 of the terminal 100 and the lance 220 are in the height direction and the locking portion 221 of the lance 220 protrudes in the first storage chamber 211. It is comprised so that it may not overlap seeing from the direction orthogonal to.

  The contact portion 110 of the terminal 100 is accommodated in the first accommodation chamber 211 of the housing body 210, the connection portion 120 of the terminal 100 is accommodated in the second accommodation chamber 212, and the terminal The locking portion 221 of the lance 220 is hooked on the step portion 130 of 100.

  The end surface 221b on the higher side in the height direction of the locking portion 221 is inclined so as to go to the first storage chamber 211 as it goes toward the lower side in the height direction.

  The housing body 210 is provided with a support portion 213. The support portion 213 is located on the opposite side of the lance 220 from the first storage chamber side and is separated from the lance 220 by an allowable amount, and corresponds to the locking portion 221 of the lance 220. It extends from the part to the higher side in the height direction. The allowable amount is an amount allowed as a deformation amount of the lance 220, for example, a deformation amount that allows the lance 220 to be within an elastic region. The support portion 213 is provided on the opposite side of the lance 220 from the first storage chamber 211 as viewed from the height direction. In other words, the support portion 213 faces the back surface of the lance 220. Here, the support portion 213 is formed in a wall shape, but may be formed in a rod shape or other shapes, for example.

  Therefore, in the case of the housing 200, when the terminal 100, in which the conductor 300 extends in a direction intersecting the fitting direction, is inserted into the housing 200 along the height direction, the terminal 100 is accommodated in the first housing. The conductors 300 are accommodated in the second accommodating chamber 212 and the second accommodating chamber 212. In the meantime, the lance 220 is elastically deformed to get over the contact portion 110 and then restored, and the locking portion 221 locks the terminal 100. In that case, when an external force toward the higher side in the height direction, that is, an external force toward the anti-fitting direction is applied to the terminal 100, the external force is received by the lance 220, so the housing 200 is in the anti-fitting direction. Strength against external force toward Further, since the lance 220 extends from the low side in the height direction to the high side, the conductor 300 or the terminal 100 in the terminal 100 as compared with the conventional lance extending from the high side in the height direction to the low side. It is difficult to interfere with the connecting portion 120 that is a connecting portion with the conductor 300. Therefore, the lance 220 can be arranged close to the inside, and the lance 220 forms a part of the flat wall, so that the housing 200 can be made compact. Further, unlike the conventional common cover, it is possible not to provide a reinforcing member for receiving the terminal 100 on the non-fitting side. When such a reinforcing member is not provided, the fitting of the housing 200 is performed. The dimension in the direction is shortened to realize a compact size, and the labor for assembling the reinforcing member to the housing 200 can be saved.

Therefore, the housing 200 of the electrical connector according to the embodiment includes the lance 220 extending in a direction opposite to the fitting direction of the terminal 100 to be accommodated, and is provided so as to form the first accommodation chamber 211 on the inner side. The lance 220 is formed by a part of the flat wall on the opposite side to the side where the stepped portion 130 of the terminal 100 falls out of the wall of the housing body 210 thus formed. While accommodating the terminal 100 in which the conductor 300 extends in the intersecting direction, it is possible to provide strength against an external force in the anti-fitting direction, and to achieve compactness.

The housing of the second electrical connector of the present invention does not limit the shape of the end face on the higher side in the height direction of the locking portion of the lance. Among such various embodiments, in the case of the electric connector housing 200 according to the above embodiment and the above modification, the end surface 221b on the higher side in the height direction of the locking portion 221 has the above height. Inclination is directed toward the first storage chamber 211 toward the lower side. In this way, the height direction of the higher side of the end face 221b of the locking portion 221, since the inclined toward the said first accommodating chamber 211 toward the low side of the height direction, When the terminal 100 is inserted into the housing 200 along the height direction, the terminal 100 is guided to the end surface 221b on the higher side in the height direction and is drawn into the first storage chamber 211, and Since the locking portion 221 is pushed to the outside of the first storage chamber 211, the possibility that the terminal 100 interferes with the lance 220 is reduced.

The housing of the first electrical connector of the present invention includes an embodiment in which the support portion is not provided, and an embodiment in which the opposite side of the lance to the first storage chamber side is open. Among the various embodiments, in the case of the electric connector housing 200 according to the embodiment and the modification, the housing body 210 is provided with a support portion 213, and the support portion 213 includes the lance. 220 is located on the side opposite to the first storage chamber side and is spaced apart from the lance 220 by an allowable amount, and is high in the height direction from a portion corresponding to the locking portion 221 of the lance 220. It extends to the side. In this way, as shown in FIG. 11, for example, the terminal 100 is inclined in the first storage chamber 211 and the second storage chamber 212 of the housing main body 210 in an obliquely inclined direction with respect to the original insertion direction. Even if the lance 220 is pushed to the outside of the first storage chamber 211 by inserting it or the like, the support portion 213 supports the lance 220 that is elastically deformed, and the lance 220 is prevented from being excessively deformed. Further, when an external force is received near the lance 220 from the outside of the housing main body 210, when the external force is received by the support portion 213, the lance 220 is prevented from being excessively deformed. FIG. 11 only illustrates one state, for example, the shape of the first storage chamber, the second storage chamber, the terminal, the lance, or the end face of the lance on the higher side in the height direction. In some cases, this prevents the terminal from hitting the lance obliquely.

  The housing of the electrical connector of the present invention includes an embodiment in which the lid is not provided. Among such various embodiments, in the case of the electric connector housing 200 of the above embodiment and the above modification, on the higher side in the height direction of the second housing chamber 212 of the housing body 210, The lid 214 is provided. If it does in this way, the said terminal 100 will be interrupted | blocked from the outside by the said lid | cover 214, and performance, such as insulation and dustproofness, etc. of the said terminal 100 will improve. Further, depending on the mounting strength of the lid 214 to the housing body 210, the strength of the housing 200 against an external force in the counter-fitting direction is improved.

Moreover, the electrical connector of this invention was fully disclosed by the above description. That is, the electrical connector C of the present invention is provided on the contact portion 110 that comes into contact with the mating conductive member, and on the higher side of the height direction than the contact portion 110, and the height direction The stage having the connecting portion 120 for connecting the terminal end of the conductor 300 introduced along the intersecting direction, and descending in a direction intersecting the height direction when going to a higher side in the height direction. The terminal 100 provided with the portion 130 and the housing 200 that houses the terminal 100 are provided. The housing 200 communicates with the first storage chamber 211 that extends in the height direction and has both ends in the height direction opened to the outside, and a higher end of the first storage chamber 211. The housing body 210 provided so as to form the second storage chamber 212 extending in a direction intersecting the height direction and having the high side in the height direction open to the outside, and the height direction The end of the lower side in the height direction is provided in the housing main body 210, and the first accommodation is placed on the upper end in the height direction. The locking portion 221 protruding to the chamber side is provided, and the lance 220 having elasticity is provided. The contact portion 110 of the terminal 100 is accommodated in the first accommodating chamber 211, and the connection portion of the terminal 100 is provided. 20 is accommodated in the second accommodating chamber 212, and the locking portion 221 of the lance 220 is hooked on the stepped portion 130 of the terminal 100, so that the first accommodating chamber 211 is formed inside. Of the walls of the housing main body 210 provided on the wall , the wall opposite to the side where the stepped portion 130 falls is formed in a flat plate shape, and the lance 220 forms a part of the flat plate wall. The contact portion 110 and the lance 220 of the terminal 100 in the first storage chamber 211 are seen from the direction perpendicular to the height direction and the direction in which the locking portion 221 of the lance 220 protrudes. It is configured not to overlap. An end face on the higher side in the height direction of the locking portion 221 is inclined so as to go to the first storage chamber 211 toward the lower side in the height direction. The housing main body 210 is provided with the support portion 213, and the support portion 213 is located on the opposite side of the lance 220 from the first storage chamber side and is separated from the lance 220 by an allowable amount. The lance 220 extends from the portion corresponding to the locking portion 221 to the higher side in the height direction.

  When an external force toward the higher side in the height direction, that is, an external force toward the anti-fitting direction is applied to the terminal 100, the external force is received by the lance 220. Therefore, the housing 200 has an external force toward the anti-fitting direction. With strength against. Further, since the lance 220 extends from the low side in the height direction to the high side, the conductor 300 or the terminal 100 in the terminal 100 as compared with the conventional lance extending from the high side in the height direction to the low side. It is difficult to interfere with the connecting portion 120 that is a connecting portion with the conductor 300. Therefore, the lance 220 can be arranged close to the inside, and the lance 220 forms a part of the flat wall, so that the housing 200 can be made compact. Further, unlike the conventional common cover, it is possible not to provide a reinforcing member for receiving the terminal on the non-fitting side. When such a reinforcing member is not provided, the fitting direction of the housing 200 is not provided. Thus, the size of the housing can be shortened to realize a compact size, and the labor for assembling the reinforcing member to the housing 200 can be saved. Further, when an external force toward the high side in the height direction, that is, an external force toward the anti-fitting direction is applied to the terminal 100, the lance 220 extends from the low side in the height direction to the high side. The lance 220 receives an external force from the terminal 100 toward the higher side in the height direction, and this acts as a pulling force. On the other hand, since the conventional lance extends from the high side in the height direction to the low side, the conventional lance receives a compressive force under the same load condition. In addition, since the conventional lance extends obliquely with respect to the insertion direction so as not to twist the lance when the terminal is inserted into the receiving chamber, the conventional lance receiving the compression force is seated. There is a tendency to bow. On the other hand, the lance 220 can be extended straight in the height direction, and the tensile force acts, for example, a bending force or the like is difficult to act. There is a case.
