Description

  The present invention relates to a connector for detachably connecting printed circuit boards arranged in parallel to each other.

Conventionally, this type of connector has a configuration as shown in FIG. The connector 50 includes a socket 51 mounted on one of the printed boards P1 and P2 and a header 52 mounted on the other. Inside the connection recess 53 of the socket 51, a plurality of contacts 54a and 54b connected to a circuit on the printed circuit board P1 are provided. The header 52 includes an insertion portion 55 that is inserted into and coupled to the connection recess 53 of the socket 51, and the insertion portion 55 is provided with a plurality of contacts 56 a and 56 b that are in contact with the contacts 54 a and 54 b of the socket 51. ing. When the insertion portion 55 of the header 52 is inserted into the connection recess 53 of the socket 51, the contacts 54a, 54b of the socket 51 and the contacts 56a, 56b of the header 52 are electrically connected, and both the printed boards P1, P2 are connected to each other. 50 is electrically connected.
Japanese Patent Laid-Open No. 2000-100501

  However, in the connector 50 described in the above publication, when the socket 51 and the header 52 mounted on the printed circuit boards P1 and P2 are to be connected to each other, the connection work is made closer to the printed circuit boards P1 and P2. It is necessary to carry out while moving. Therefore, since the connector 50 cannot be mounted alone after the positional relationship between the two printed circuit boards P1 and P2 is fixed, the connection workability of the connector 50 is poor.

  Further, in technologies other than the above publication, when trying to connect the two printed circuit boards P1 and P2 whose positional relationship is already fixed to each other by the connector 50, the positional relationship between the two printed circuit boards P1 and P2 is determined from the predetermined positional relationship. It may be off. When the header 52 of the printed circuit board P2 is connected to the socket 51 of the printed circuit board P1 in such a state, the contacts 56a and 56b of the header 52 are not in a form that is flexibly deformed. Power is applied. As a result, the connection state between the socket 51 and the header 52 may be deteriorated, or the contact state of the contacts 54a, 54b, 56a, 56b with respect to the printed circuit boards P1, P2 may be deteriorated.

  Furthermore, since the contacts 56a and 56b of the socket 51 are exposed to the outside, the assembly operator's hand is easy to touch carelessly and surrounding dust is likely to adhere. As a result, the insulation between the contacts 56a and 56b was likely to be impaired.

  The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a connector that can easily connect printed circuit boards arranged in parallel to each other and has improved insulation between contacts.

  It is another object of the present invention to provide a connector that can reasonably connect printed circuit boards fixed in a state shifted from a predetermined positional relationship.

  In order to achieve the above object, the present invention is a connector for electrically connecting two printed circuit boards arranged in parallel to each other, and is mounted on each printed circuit board and mounted on each printed circuit board. A pair of receptacles each having a plurality of substrate contacts arranged along the surface, and a connection member that electrically communicates between the two receptacles, which can be coupled to each of the receptacles A pair of holders and a plurality of connection contacts disposed between the two holders, and in the coupled state of the holders to the receptacles, the contact contacts are connected between the substrate contacts of the receptacles. Furthermore, the connection contacts are covered in a state of being fixed to the both holders or both receptacles. It characterized in that a rim member made cover.

  According to this configuration, the printed circuit boards are connected to each other via the connection members by coupling the holders of the connection members to the receptacles on the two printed circuit boards arranged in parallel with each other in the thickness direction of the printed circuit boards. Connected. Therefore, since it is not necessary to move the printed board in order to connect the connecting member to both receptacles, it is easy to connect the connector to the printed board. Furthermore, the cover made of an insulating material that covers each connection contact in a state of being fixed to both holders or both receptacles protects each connection contact from human contact, dust, and the like, and improves the insulation.

Moreover, in this invention, the said connection contact has a bending part or a curved part which accept | permits the change of the positional relationship of the both ends.
According to this configuration, when a connector is mounted on a printed circuit board that is fixed in a state of being deviated from a predetermined positional relationship, the bending portion or the bending portion of each connection contact is elastically deformed, and the positional relationship between the two holders changes. Is acceptable. Therefore, since an excessive force is prevented from being applied to both the holder and the receptacle, it is possible to prevent deterioration of the coupling state between the holder and the receptacle.

  Further, in the present invention, the cover is integrally formed with an interposition part for preventing contact between the connection contacts by interposing between the adjacent connection contacts.

  According to this structure, the interposition part integrally formed in the cover interposes between the connection contacts, and prevents contact between the connection contacts. Therefore, since it is not necessary to provide a separate member for preventing contact between the connection contacts, an increase in the number of parts is prevented, and further, an increase in the number of assembly steps is prevented.

  In the present invention, a first engagement portion is integrally formed at a position corresponding to each holder in the cover, and the first engagement is formed in each holder in the thickness direction of the printed circuit board. The second engaging portions that engage with the first engaging portion are integrally formed, and the cover is fixed to both holders by the engagement of the second engaging portions with the first engaging portions. .

  According to this configuration, the cover is fixed to both holders by engaging the second engaging portion formed in each holder in the thickness direction of the printed circuit board with respect to the first engaging portion formed in the cover. Is done. For this reason, when the cover is removed from the connector, the connecting member that is still coupled to the cover is detached from each receptacle. Therefore, since the connecting member can be removed from both receptacles together with the cover, the connecting member can be easily removed, unlike the case where the connecting member is directly removed from both receptacles without using the cover. Further, since the connection member is removed from both receptacles while maintaining the positional relationship between the two holders, it is possible to prevent excessive force from being applied to each connection contact, and to prevent deformation of each connection contact.

  According to the present invention, the first engagement portion is an opening formed in a side wall portion of the cover, and the second engagement portion is formed to protrude from a side surface of the holder and is disposed in the opening. It is a convex engagement part which is characterized by making the width direction inner method of the said opening part larger than the width | variety of the said convex engagement part in the same direction.

  According to this configuration, when the cover is attached to the connector attached to both printed circuit boards in a state where the positional relationship in the approach and separation directions between the receptacles is shifted, the movement of the convex engagement portion in the opening portion Changes in the distance between both holders in the same direction are allowed. As a result, an excessive force is prevented from being applied from the cover to the holder coupled to the receptacle. Therefore, the cover is easily attached to the connector connected to both printed circuit boards that are displaced in the same direction, and the deterioration of the coupling state between the holder and the receptacle due to the attachment of the cover is prevented.

In the present invention, the cover is formed with an elastically deforming portion that is elastically deformed so as to allow a positional shift between the two printed circuit boards.
According to this configuration, when the cover is attached to the connectors attached to both printed circuit boards in a state in which the positions in the orthogonal direction with respect to the approach and separation directions of the two receptacles are shifted from each other, the elastically deforming portion formed integrally with the cover Due to the elastic deformation, a change in the positional relationship between the two holders in the same direction is allowed. As a result, an excessive force is prevented from being applied from the cover to the holder coupled to the receptacle. Therefore, the cover is easily attached to the connector connected to both printed circuit boards that are displaced in the same direction, and the deterioration of the coupling state between the holder and the receptacle due to the attachment of the cover in this misaligned state is prevented. Is done.

  According to the present invention, printed circuit boards arranged in parallel to each other can be easily connected to each other, and insulation between contacts can be improved. In addition, printed boards that deviate from a predetermined positional relationship can be connected without difficulty.

Furthermore, “U” -shaped gaps 45 are formed on both sides of the vertical wall 43 in the top plate portion of the cover 13. Due to the gap 45, an elastically deformable portion 46 that allows mutual displacement of both side portions of the vertical wall 43 is formed in the central portion of the cover 13.

Next, the operation of this embodiment configured as described above will be described.
In order to electrically connect two printed circuit boards P1 and P2 arranged in parallel to each other by the connector 10, a receptacle 11 is mounted on each printed circuit board P1 and P2, and the receptacles 11 are connected to each other by a connecting member 12. To do. At this time, each holder 17 is coupled to the receptacle 11 by inserting the connection convex portion 30 of the holder 17 of the connection member 12 into the connection concave portion 20 of the receptacle 11 mounted on each printed circuit board P1, P2. In this coupled state, as shown in FIG. 3, each first connection contact 18 is in contact with each first substrate contact 15 of the receptacle 11, and each second connection contact 19 is in each second state. Each is in contact with the substrate contact 16. Therefore, the connector 10 is mounted between the two printed circuit boards P1 and P2 without moving the two printed circuit boards P1 and P2 along the same plane.

  As shown by a two-dot chain line in FIG. 8, when the covers 13 are to be put on both the holders 17 in order to attach them to the both holders 17, the slopes 41 formed at the lower ends of the both side walls of the cover 13 Abuts against corners and parts. Therefore, even if there is a slight shift in the positional relationship between the cover 13 and the holders 17, the positional deviation of the cover 13 relative to the holder 17 is corrected by this contact. When the cover 13 is pushed down from this state, as shown by a two-dot chain line in FIG. 8, the inclined surface 41 hits the inclined surface of the convex engaging portion 37, and both side walls thereof escape to the outside as the cover 13 is further pushed down. The both side walls get over the convex engagement portion 37 by this elastic deformation. When the opening 40a (or 40b) reaches the position of the convex engagement portion 37 as the cover 13 is pushed down, both side walls of the cover 13 return to their original state due to their elasticity, and a solid line in FIG. As shown, the opening 40a (or 40b) engages with the convex engagement portion 37. At this time, the lower surface of the top wall of the cover 13 contacts the upper surfaces of both holders 17. As a result, the cover 13 is fixed to the both holders 17 while covering the connecting member 12 and the receptacles 11. In this state, since the connection member 12 and the receptacles 11 are covered by the cover 13, an operator carelessly cares about the first and second connection contacts 18 and 19 and the first and second substrate contacts 15 and 16. It will not be touched or the surrounding dust will adhere.

  Further, as shown in FIG. 7, when the cover 13 is attached, the interposition portions 44 formed on the vertical wall 43 are between the adjacent first connection contacts 18 and between the second connection contacts 19. It will be in the state which intervened.

  By the way, when the connecting member 12 is attached to the receptacles 11 together with the cover 13, the positional relationship between the printed boards P1 and P2 is in the X direction shown in FIG. 1 (that is, in the plane in which the printed boards P1 and P2 are arranged). In this case, the two receptacles 11 may be closer than the predetermined positional relationship in the approach and separation directions. In such a case, when the holders 17 of the connection member 12 are attached to the receptacles 11, as shown in FIG. 11A, the bent portions 18b and 19b of the first and second connection contacts 18 and 19 are provided. As the degree of bending increases, the connecting portions 18a and 19a curve upward. For this reason, the space | interval between both the holders 17 reduces easily, and each holder 17 is each mounted | worn with the receptacle 11 without difficulty. At this time, as shown in FIG. 10, as the printed circuit boards P <b> 1 and P <b> 2 approach each other, the convex engagement portion 37 moves in the opening 40 b of the cover 13, and the distance between the holders 17 is increased. Reduction is allowed. As a result, an excessive force is prevented from being applied from the cover 13 to the holder 17 coupled to each receptacle 11.

  Further, when the connecting member 12 is attached to the receptacles 11 together with the cover 13, the positional relationship between the printed boards P1 and P2 may be separated from the predetermined positional relationship in the X direction shown in FIG. In such a case, if the holders 17 of the connection member 12 are to be attached to the receptacles 11, the bending of the first and second connection contacts 18, 19 of the connection member 12 as shown in FIG. The bending degree of the parts 18b and 19b becomes weak. For this reason, the space | interval between both the holders 17 increases without difficulty, and each holder 17 is each attached to the receptacle 11 without difficulty. At this time, as shown in FIG. 10, as the printed circuit boards P <b> 1 and P <b> 2 are separated from each other, the convex engaging portion 37 moves in the opening 40 b of the cover 13, and the distance between the holders 17 is increased. Increase is allowed. As a result, an excessive force is prevented from being applied from the cover 13 to the holder 17 coupled to each receptacle 11.

  When the connecting member 12 is mounted on both receptacles 11, the positional relationship between the printed boards P1 and P2 is in the Y direction shown in FIG. 1 (that is, between the receptacles 11 in the arrangement plane of the printed boards P1 and P2). There is a case that the predetermined positional relationship is deviated in the direction orthogonal to the approaching and separating directions. In such a case, the adjacent first and second connection contacts 18 and 19 may be in contact with each other. However, since the interposition part 44 formed in the cover 13 is interposed between the adjacent first and second connection contacts 18 and 19, respectively, the adjacent first and second connection contacts 18 and 19 are adjacent to each other. Is prevented from touching. At this time, as shown in FIG. 9, the elastic deformation portion 46 of the cover 13 is elastically deformed, and the positional displacement between the holders 17 is allowed by this elastic deformation. As a result, an excessive force is prevented from being applied from the cover 13 to the holder 17 coupled to each receptacle 11.

  Furthermore, the cover 13 is fixed to each holder 17 by the convex engagement portion 37 of each holder 17 engaging the openings 40 a and 40 b of the cover 13. For this reason, when the cover 13 is removed from both the holders 17 in the thickness direction of the printed circuit boards P <b> 1 and P <b> 2, the connection member 12 is detached from both the receptacles 11 together with the cover 13.

This embodiment described in detail above has the following effects.
(1) A connector 10 for electrically connecting two printed circuit boards P1 and P2 arranged in parallel to each other is provided with a receptacle 11 mounted on each printed circuit board P1 and P2, and the printed circuit boards P1 and P1 with respect to the receptacle 11. The connecting member 12 has a holder 17 coupled to P2. Therefore, since it is not necessary to move the printed circuit boards P1 and P2 in order to connect the connecting member 12 to each receptacle 11, the connector 10 can be easily attached to the printed circuit boards P1 and P2.

  Further, the connector 10 is provided with a cover 13 that covers the connection member 12 and the receptacles 11 while being fixed to the holders 17. Therefore, the first and second connection contacts 18 and 19 of the connection member 12 and the first and second substrate contacts 15 and 16 of the receptacle 11 are protected from human contact, dust and the like, and the insulation thereof is improved. Can do.

  (2) The first and second connection contacts 18 and 19 are formed with bent portions 18b and 19b. Therefore, when the connector 10 is mounted on the printed circuit boards P1 and P2 that are fixed in a state of being deviated from the predetermined positional relationship, the bent portions 18b and 19b are elastically deformed to allow the positional relationship between the holders 17 to be changed. The Therefore, it is possible to prevent an excessive force from being applied to both the holder 17 and the receptacle 11, and it is possible to prevent deterioration of the coupling state between the holder 17 and the receptacle 11.

  (3) Since the cover 13 is interposed between the adjacent first connection contacts 18 and between the adjacent second connection contacts 19, the first connection contacts 18 and the second connection contacts 19 can be connected to each other. The interposition part 44 for preventing contact was formed integrally. Therefore, when the two printed circuit boards P1 and P2 that are fixed and shifted from the predetermined positional relationship are connected by the connector 10, it is possible to prevent a decrease in the interval between the adjacent first connection contacts 18 and the second connection contacts 19. The contact between the first and second connection contacts 18, 19 can be prevented. Therefore, it is not necessary to separately provide a member for preventing the first and second connection contacts 18, 19 from contacting each other, so that the number of parts is not increased and the number of assembly steps is not increased. it can.

  (4) The openings 13a and 40b are formed in the cover 13, and the convex engagement portions 37 that are engaged with the openings 40a and 40b are formed in the holders 17 respectively. The cover 13 is configured to be fixed to both the holders 17 by the engagement of the shape engaging portions 37. Therefore, since the connecting member 12 can be removed from both receptacles 11 together with the cover 13, the connecting member 12 can be easily removed unlike the case where the connecting member 12 is directly removed from both receptacles 11 without the cover 13 interposed therebetween.

  In addition, since the connection member 12 can be removed from both the receptacles 11 while maintaining the positional relationship between the two holders 17, it is possible to prevent an excessive force from being applied to the first and second connection contacts 18, 19. The deformation of the second connection contacts 18 and 19 can be prevented.

  (5) Since the inner width L2 of the opening 40b is made larger than the width W of the convex engaging portion 37, the positional deviation between the two holders 17 in the X direction shown in FIG. An excessive force is prevented from being applied to the holder 17 from the cover 13. Accordingly, the cover 13 can be easily mounted on the connector 10 connected to the printed circuit boards P1 and P2 that are displaced in the X direction, and the holder 17 and the receptacle 11 are connected to each other when the cover 13 is mounted. Deterioration can be prevented.

  (6) Due to the elastic deformation of the elastic deformation portion 46 formed on the cover 13, the positional relationship between the holders 17 in the Y direction shown in FIG. 1 is allowed to be shifted, and the holder 17 coupled to the receptacle 11 is moved from the cover 13 to the holder 17. Unreasonable force is prevented from being applied. Therefore, the cover 13 can be mounted without difficulty on the connector 10 connected to both printed circuit boards P1 and P2 that are displaced in the Y direction, and the holders 17 and the receptacles 11 are connected to each other when the cover 13 is mounted. Deterioration can be prevented.

In addition, this embodiment can also be changed and embodied as follows.
In place of the bent portions 18b and 19b, the first and second connection contacts 18 and 19 are provided with curved portions that allow a change in the positional relationship between the both ends thereof.

Further, the first and second connection contacts 18 and 19 are provided with a bent portion and a bent portion that allow a change in the positional relationship between the both ends thereof.
In place of the convex engagement portion 37 formed on the holder 17, a convex engagement portion having a similar shape is formed on the receptacle 11, and the openings 40a and 40b of the cover 13 are engaged with the convex engagement portion. Configure to match. Then, the cover 13 is fixed to the receptacles 11 by the engagement of the convex engagement portions with the openings 40a and 40b.

-The interposition part 44 is formed in another member joined to the main body of the cover 13.
The present invention is applied to the connector 10 constituted by the receptacle 11 provided with only the substrate contact corresponding to the first substrate contact 15 and the connection member 12 provided only with the connection contact corresponding to the first connection contact 18.
