Description

  The present invention relates to a connector for electrically connecting a substrate and an electric wire.

  Conventionally, a connector is used when a substrate and an electric wire are electrically connected. As such a connector, the connector disclosed in Patent Document 1 is known.

  The connector disclosed in Patent Document 1 includes a metal first terminal (contact) attached to an electric wire and a metal second terminal (contact) mounted on a substrate. The second terminal has a housing portion formed in a cylindrical shape, and the first terminal has an insertion portion to be inserted into the housing portion.

Japanese Patent No. 4885320

  According to the connector disclosed in Patent Document 1, the direction in which the electric wire extends from the first terminal is parallel to the direction in which the insertion portion is inserted into the housing portion. When the first terminal is fitted and connected to the second terminal, the insertion portion of the first terminal is parallel to the direction in which the electric wire extends from the first terminal and parallel to the surface of the substrate. It inserts in the accommodating part of a 2nd terminal along a direction. Due to this configuration, when the worker performs the fitting operation of fitting the first terminal to the second terminal, the electric wire is once largely bent before the insertion portion of the first terminal is inserted into the housing portion of the second terminal. It will be necessary. For this reason, there is a problem that the fitting work becomes difficult and the workability of the connecting work is lowered depending on the condition of the electric wire or the board in which the connector is used.

  More specifically, for example, when the length of the electric wire connected to the first terminal is short, it becomes difficult to temporarily curve the electric wire and fit the first terminal to the second terminal. There is a problem that the performance is lowered. Further, when the second terminal is mounted near the center of the surface of the board, when the electric wire is once greatly bent and the first terminal is fitted to the second terminal, a space for the electric wire to be bent is obstructed by the board. There is a problem that the fitting work is difficult and the workability is lowered. In addition, when the above connector is used in a device in which a plurality of boards are installed close to each other, the space around the board on which the second terminal is mounted is small, so a space for largely bending the electric wire is secured. This makes it difficult to fit the first terminal to the second terminal, resulting in a problem that workability is reduced.

  In view of the above circumstances, the present invention can suppress the difficulty in fitting metal contacts due to the condition of the electric wire or board on which the connector is used, and lower the workability of the connection work. It aims at providing the connector which can suppress this.

(1) A connector according to an aspect of the present invention for achieving the above object relates to a connector for electrically connecting an electric wire and a substrate. The connector according to an aspect of the present invention includes a metal first contact connected to the electric wire, and a metal mounted on the surface of the substrate and connected to the substrate and connected to the first contact. A second contact made from the first contact and the second contact, wherein one of the first contact and the second contact is one of the first contact and the second contact. An engagement mechanism is provided for engaging the first contact and the second contact with each other when the other contact is fitted and the electric wire in a state connected to the first contact is provided. The one contact contacts the other contact along a direction parallel to a direction perpendicular to the wire extension direction, which is a direction extending from the first contact. By fitting crowded fits against, by the engagement mechanism, and the first contact and the second contact is coupled.

  According to this configuration, one contact fits into the other contact along a direction parallel to the direction perpendicular to the wire extension direction, so that both contacts are engaged with each other and coupled. For this reason, the electric wire extension direction and the direction parallel to the direction in which one contact is fitted to the other contact are set perpendicular to each other. Thereby, when an operator performs a fitting operation for fitting one contact to the other contact, it is not necessary to bend the electric wire once and the one contact is easily fitted to the other contact. be able to. Therefore, according to said structure, it can suppress that the fitting operation | work of metal contacts will become difficult by the conditions of the electric wire or board | substrate with which a connector is used. And it can suppress that the workability | operativity of the connection operation | work which connects the 1st contact connected to the electric wire and the 2nd contact connected to the board | substrate falls.

Can be fitted along any direction. For this reason, in the case of a fitting operation, it is not necessary to once bend the electric wire greatly, and in addition, a state in which the board can interfere with the fitting operation hardly occurs. Therefore, the fitting work between the contacts can be performed more easily, and the workability of the connecting work can be further improved.

(3) The engagement mechanism includes: a first engagement portion provided on the one contact; and a second engagement portion provided on the other contact and engaged with the first engagement portion. The first engagement portion is provided so as to protrude outward from the wall portion of the one contact, and the one contact is along a direction parallel to a direction perpendicular to the wire extension direction.

It is preferable.

  According to this configuration, the engagement mechanism includes the first engagement portion that protrudes outward from the wall portion of one contact and the second engagement portion of the other contact that engages with the first engagement portion. Is done. For this reason, the engagement mechanism which engages both the contacts with each other at the time of fitting and reliably connects them can be configured with a simple structure.

(4) The first engagement portion is both in a direction parallel to the wire extension direction and in a direction parallel to a direction perpendicular to the wire extension direction with respect to the second engagement portion. It is preferred to engage in the direction.

  According to this configuration, the first engagement portion of one contact is in both directions parallel to the wire extension direction and parallel to the wire extension direction with respect to the second engagement portion of the other contact. Engage in. For this reason, the other contact can be more firmly coupled to one contact. And even if it is a case where the external force of a various direction acts with respect to an electric wire, the connection state of contacts can be maintained more firmly.

(5) The second engagement portion is provided in a first wall portion which is a part of the wall portion of the other contact and has a through hole with which the first engagement portion is engaged. The one engaging portion is provided so as to extend in a cantilever manner, and a portion on the distal end side extending in a cantilever manner is provided so as to spread outward toward the distal end side with respect to the one contact, It is preferable that a tip side portion of the first engaging portion engages with an edge portion of the through hole in the first wall portion.

  According to this configuration, at the time of fitting, the tip side portion of the first engagement portion that extends in a cantilever shape and expands outwardly engages with the edge portion of the through hole of the first wall portion, so that both contacts Are combined. For this reason, in the connector in which one contact is fitted to the other contact, even when a force in a direction to separate one contact from the other contact is applied, the first engagement portion is more firmly The state engaged with the second engaging portion is maintained. Thereby, it is more reliably prevented that one contact comes off from the other contact, and both contacts can be more firmly coupled.

(6) The wall portion of the other contact includes a second wall portion provided with a third engagement portion that engages with the one contact, and the second wall portion includes the second wall portion. The wall portion of the contact is provided as a portion different from the first wall portion, and the third engagement portion is provided so as to protrude in a convex shape toward the inside of the other contact in the second wall portion.

  According to this configuration, since the groove is provided between the first wall portion and the second wall portion, it is possible to suppress the influence on the second wall portion when the first wall portion is elastically deformed. For this reason, even if it is a case where the 1st wall part is greatly elastically deformed so that it may open outward, the 2nd wall part will be elastically deformed so that it may open largely outward together with the 1st wall part. Can be suppressed. Thereby, the engagement state by the 1st engagement part and the 2nd engagement part and the engagement state by the 3rd engagement part can be maintained in a more independent state. Therefore, it is possible to further improve the reliability of maintaining the combined state of both contacts.

(8) The second wall portion is provided with a contact portion that contacts the one contact and electrically connects the one contact to the other contact, and the contact portion is Two wall portions are formed so as to be recessed inward from the outside of the other contact and are formed so as to protrude toward the inside of the other contact, and the second wall portion is formed by the third engagement. When the portion provided with the portion is bent, it is preferable that the portion provided with the contact portion is provided so as to be bent integrally.

  According to this configuration, when the second wall portion is elastically deformed and bent when the third engaging portion is engaged with one of the contacts, the portion of the second wall portion where the contact portion is provided is also bent. Become. When the elastic deformation of the second wall portion is recovered and the third engaging portion is engaged with one contact, the contact portion protruding inside the other contact comes into contact with the one contact. . For this reason, the operation of electrically connecting the other contact to one contact and the engagement operation of the third engagement portion can be interlocked. Further, the engaging operation of the third engaging portion is performed with the recovery of the elastic deformation of the second wall portion. For this reason, in the engaging operation of the third engaging portion, instantaneous vibration is generated between the first contact and the second contact, and a click sound (clicking sound) is generated. As a result, an operator who connects one contact to the other contact confirms the momentary vibration or click sound described above and confirms the engagement operation of the third engagement portion, so that one contact becomes the other. It is possible to easily confirm that the fitting of one contact to the other contact is completed.

  According to the present invention, it is possible to prevent the fitting work between metal contacts from being difficult due to the condition of the electric wire or the board in which the connector is used, and to suppress the reduction in workability of the connecting work.

[Combination of first contact and second contact]
Next, the state where the first contact 11 and the second contact 12 are combined will be described in more detail with reference to FIGS.

  FIG. 12 is a perspective view of the connector 1 and is a perspective view showing a state in which the contacts are connected, that is, a state in which the first contact 11 and the second contact 12 are connected. FIG. 13 is a plan view of the connector 1 and shows a state in which the contacts are connected to each other. FIG. 14 is a cross-sectional view of the connector 1 and shows a cross-section viewed from the position of the arrow CC in FIG. FIG. 15 is a cross-sectional view of the connector 1 and shows a cross-section as viewed from the DD arrow position in FIG. 13. 16 is a cross-sectional view of the connector 1 and shows a cross-section as viewed from the position of the arrow EE in FIG. 12 to 16 show a state in which the contacts are connected to each other, that is, a state in which the first contact 11 and the second contact 12 are combined. In FIGS. 12 and 13, a part of the electric wire 100 connected to the first contact 11 is illustrated, but the substrate 101 to which the second contact 12 is connected is omitted.

  As described above, the main body portion 11a of the first contact 11 is fitted into the main body portion 12a of the second contact 12 so that the first engagement portion 14 and the second engagement portion 15 are included. The first contact 11 and the second contact 12 are coupled by the coupling mechanism 13. In the state where the first contact 11 and the second contact 12 are coupled by the engagement mechanism 13, the first contact 11 (one contact 11) is connected as shown in FIGS. 3, 4, 12 to 14. The provided first engaging portion 14 is engaged with a second engaging portion 15 provided on the second contact 12 (the other contact 12).

  Further, when the first contact 11 is fitted to the second contact 12, the first engagement portion 14 provided so as to protrude outward from the wall portion 19 of the first contact 11 and extend in a cantilevered manner, It abuts on the inside of the first wall portion 23 of the second contact 12. As a result, the portion of the first wall portion 23 provided with the second engagement portion 15 is once bent toward the outside of the second contact 12. Then, in the state where the fitting of the first contact 11 to the second contact 12 is completed, the first wall portion 23 once bent outward is elastically recovered. Thereby, the first engaging portion 14 is configured such that a portion on the distal end side thereof engages with an edge portion of the through hole 26 in the first wall portion 23 of the second contact 12.

  Furthermore, the first engagement portion 14 is perpendicular to the second engagement portion 15 in a direction parallel to the wire extension direction (the direction indicated by arrow A in FIGS. 12 and 13) and the wire extension direction. Engage in both directions parallel to the normal direction. More specifically, the first engagement portion 14 is in a direction parallel to the wire extension direction with respect to the edge portion of the through hole 26 in the first wall portion 23 of the second contact 12 and the wire extension direction. Engage in both a direction parallel to the vertical direction and perpendicular to the surface 101a of the substrate 101.

  Further, as described above, when the first contact 11 is fitted to the second contact 12, the first contact 11 and the second contact 12 are also coupled by the third engagement portion 20 and the engagement recess 18. The That is, when the first contact 11 and the second contact 12 are combined, as shown in FIGS. 3, 4, 12, 13, and 15, the second contact 12 (the other contact 12) is provided. The third engaging portion 20 is engaged with an engaging recess 18 provided in the first contact 11 (one contact 11).

  In addition, when the first contact 11 is fitted to the second contact 12, the third engagement portion 20 that protrudes inwardly from the wall portion 24 of the second contact 12 is provided in the first contact 11. By contacting the outside of the wall portion 19 of the contact 11, the contact 11 is once bent toward the outside of the second contact 12. And in the state where the fitting of the first contact 11 to the second contact 12 is completed, the third engagement portion 20 that has once bent outwardly recovers elastically. Accordingly, the third engagement portion 20 is configured to engage with the edge portion of the engagement recess 18 in the wall portion 19 of the first contact 11.

  Further, as described above, in a state where the first contact 11 and the second contact 12 are coupled, the first contact 11 and the second contact 12 are electrically connected. That is, as clearly shown in FIG. 16, the contact portion 27 formed so as to protrude inward in the wall portion 22 of the second contact 12 is in contact with the outer surface of the wall portion 19 of the first contact 11. The contact is made in the pressed state. Thereby, the first contact 11 and the second contact 12 are configured to be reliably electrically connected in a combined state.

[Operation and effect of this embodiment]
According to the present embodiment, one contact 11 (first contact 11) is fitted into the other contact 12 (second contact 12) along a direction parallel to a direction perpendicular to the wire extension direction. Thus, both contacts (11, 12) are engaged with each other and coupled. For this reason, the electric wire extension direction and the direction parallel to the direction in which one contact 11 is fitted to the other contact 12 are set perpendicular to each other. Thereby, when the operator performs a fitting operation for fitting one contact 11 to the other contact 12, it is not necessary to bend the electric wire 100 once greatly, and one contact 11 is made to the other contact 12. It can be easily fitted. Therefore, according to this embodiment, it can suppress that the fitting operation | work between metal contacts (11, 12) becomes difficult by the conditions of the electric wire 100 or the board | substrate 101 in which the connector 1 is used. And it can suppress that the workability | operativity of the connection operation | work which connects the 1st contact 11 connected to the electric wire 100 and the 2nd contact 12 connected to the board | substrate 101 falls.

  Therefore, according to the present embodiment, it is possible to prevent the fitting work between the metal contacts (11, 12) from being difficult due to the condition of the electric wire 100 or the substrate 101 in which the connector 1 is used, and the workability of the connecting work. It is possible to provide the connector 1 that can suppress the decrease in the resistance.

  Further, according to the present embodiment, when the operator performs a fitting operation for fitting one contact 11 to the other contact 12, the one contact 11 is perpendicular to the other contact 12 in the wire extension direction. And can be fitted along a direction perpendicular to the surface of the substrate 101. For this reason, in the fitting operation, the electric wire 100 does not need to be largely bent once, and the state in which the board 101 can hinder the fitting operation hardly occurs. Therefore, the contact work between the contacts (11, 12) can be performed more easily, and the workability of the connection work can be further improved.

  In addition, according to the present embodiment, the engagement mechanism 13 includes the first engagement portion 14 that protrudes outward from the wall portion 19 of the one contact 11, and the other contact 12 that engages with the first engagement portion 14. And the second engaging portion 15. For this reason, the engagement mechanism 13 that engages the two contacts (11, 12) with each other at the time of fitting can be configured with a simple structure.

  In addition, according to the present embodiment, the first engagement portion 14 of one contact 11 is perpendicular to the wire extension direction and the direction parallel to the wire extension direction with respect to the second engagement portion 15 of the other contact 12. Engage in both directions parallel to the direction. For this reason, the other contact 12 can be more firmly coupled to one contact 11. And even if it is a case where the external force of a various direction acts with respect to the electric wire 100, the connection state of contacts (11, 12) can be maintained more firmly.

  Further, according to the present embodiment, at the time of fitting, a portion on the distal end side of the first engaging portion 14 that extends in a cantilevered manner and spreads outward is an edge portion of the through hole 26 of the first wall portion 23. Engage and both contacts (11, 12) are coupled. For this reason, in the connector 1 in a state where one contact 11 is fitted to the other contact 12, even if a force in a direction to separate the one contact 11 from the other contact 12 is applied, the first engagement The state in which the portion 14 is more firmly engaged with the second engaging portion 15 is maintained. Thereby, it is more reliably prevented that one contact 11 is detached from the other contact 12, and both contacts (11, 12) can be more firmly coupled.

  Further, according to this embodiment, when one contact 11 is fitted to the other contact 12, the first engagement portion 14 of one contact 11 is engaged with the second engagement portion 15 of the other contact 12. At the same time, the third engagement portion 20 of the other contact 12 is engaged with the one contact 11. For this reason, both contacts (11, 12) can be combined more firmly.

  Moreover, according to this embodiment, since the groove | channel 25 is provided between the 1st wall part 23 and the 2nd wall part 24, when the 1st wall part 23 elastically deforms, it is to the 2nd wall part 24 The influence can be suppressed. For this reason, even if the first wall portion 23 is greatly elastically deformed so as to open outward, the second wall portion 24 is elastically deformed so as to be greatly opened outward together with the first wall portion 23. Can be suppressed. Thereby, the engagement state by the 1st engagement part 14 and the 2nd engagement part 15 and the engagement state by the 3rd engagement part 20 can be maintained in the more independent state. Therefore, it is possible to further improve the reliability of maintaining the state where both the contacts (11, 12) are coupled.

  In addition, according to the present embodiment, when the second wall portion 24 is elastically deformed and bent when the third engagement portion 20 is engaged with the one contact 11, the contact portion 27 in the second wall portion 24 is provided. That part will also bend. When the elastic deformation of the second wall portion 24 is recovered and the third engagement portion 20 is engaged with the one contact 11, the contact portion 27 that protrudes inside the other contact 12 becomes the one contact 11. Will come into contact. For this reason, the operation of electrically connecting the other contact 12 to one contact 11 and the engagement operation of the third engagement portion 20 can be interlocked. Further, the engaging operation of the third engaging portion 20 is performed with the recovery of the elastic deformation of the second wall portion 24. For this reason, during the engagement operation of the third engagement portion 20, instantaneous vibration is generated between the one contact 11 and the other contact 12, and a click sound (click sound) is generated. . As a result, the operator who connects one contact 11 to the other contact 12 confirms the momentary vibration or click sound described above and confirms the engagement operation of the third engagement portion 20, thereby It can be easily confirmed that the contact 11 is electrically connected to the other contact 12 and the fitting of the one contact 11 to the other contact 12 is completed.

  In addition, according to the present embodiment, the second wall portion 24 is provided so that the portion where the contact portion 27 is provided is also bent integrally when the portion where the third engagement portion 20 is provided is bent. Therefore, the insertion force required when fitting one contact 11 to the other contact 12 can be reduced. That is, according to the present embodiment, it is possible to reduce the insertion force required for inserting one contact 11 inside the other contact 12 when the worker performs the fitting operation. This point will be further described with reference to FIG.

  FIG. 17 is a cross-sectional view of the connector 1 and shows the cross-section shown in FIG. 15 in comparison with the cross-section shown in FIG. FIG. 17A corresponds to FIG. 15, and FIG. 17B corresponds to FIG. In FIG. 17A, a distance dimension L1 from the bottom of the main body 12a of the other contact 12 to the third engagement portion 20 is shown by a double-ended arrow L1. On the other hand, in FIG. 17B, a distance dimension L2 from the bottom of the main body 12a of the other contact 12 to the contact 27 is shown by a double-ended arrow L2.

  As shown in FIG. 17A and FIG. 17B, the other contact 12 has a distance dimension L1 from the bottom of the main body portion 12a to the third engagement portion 20 of the main body portion 12a. It is comprised so that it may become longer than the distance dimension L2 from a bottom part to the contact part 27. FIG. That is, the second wall portion 24 of the other contact 12 has a moment arm length (distance dimension L1) from the bottom of the main body 12a to the third engaging portion 20 from the bottom of the main body 12a to the contact 27. It is comprised so that it may become longer than the moment arm length (distance dimension L2). Further, the second wall portion 24 is provided so that the portion where the contact portion 27 is provided is also bent integrally when the portion where the third engaging portion 20 is provided is bent. For this reason, according to the present embodiment, the third engagement portion 20 is provided with a force required to deform the second wall portion 24 when the one contact 11 is inserted inside the other contact 12. This can be reduced as compared with the case of the connector form that is not. Therefore, according to the present embodiment, it is possible to reduce the insertion force required to insert one contact 11 inside the other contact 12 when the worker performs the fitting operation.
