Description

  The present invention relates to an electrical connector configured to place a signal transmission medium on a main body housing with an opening / closing lid member opened.

  In general, various electrical connectors are widely used to electrically connect various signal transmission media such as a flexible printed circuit (FPC) and a flexible flat cable (FFC) in various electrical devices. ing. For example, the electrical connector proposed in the following Patent Document 1 is used by being mounted on a printed wiring board, but the inside of the main body housing is opened by rotating the opening / closing lid member in the opening direction. The signal transmission medium such as FPC or FFC can be placed from any direction after the state is reached.

  More specifically, an opening / closing lid member is rotatably attached to the main body housing side in which a plurality of conductive contacts are arranged in a multipolar shape, and the main body housing is rotated by rotating the opening / closing lid member to an open position. Is opened, and a terminal portion of a signal transmission medium such as FPC or FFC is mounted on the medium receiving surface of the opened main housing from a substantially vertical direction, for example. After the signal transmission medium is placed on the main body housing, the opening / closing lid member is rotated to the closed position, whereby the signal transmission medium is brought into contact with the contact portion of the conductive contact. If an electrical connector having such an opening / closing lid member is used, a signal transmission medium can be connected from an arbitrary direction, so that signal transmission is performed through an elongated opening provided at the front edge of the main body housing. It is possible to work in a narrower space than an electrical connector of a type in which the medium is inserted in a substantially horizontal direction, and it is possible to connect a signal transmission medium having a short length that cannot be inserted in the horizontal direction. Further, there is an advantage that the retention property against the pulling force of the signal transmission medium is improved.

  However, in the configuration provided with the opening / closing lid member that can open the main body housing as described above, the contact of the conductive contact only with respect to the mounting surface (lower surface) of the signal transmission medium (FPC, FFC, etc.) The part is configured to be pressed. For this reason, for example, when the electrical connector becomes wider and the rigidity of the main body housing tends to decrease with the increase in the number of poles in recent years, the pressure contact load from only one side (lower side) by the conductive contact described above Due to the force, the central portion in the longitudinal direction of the main body housing is likely to be deformed, and the electrical connection between the signal transmission medium and the conductive contact may become unstable.

  With respect to such problems, the electrical connector according to Patent Document 2 below employs a configuration in which an upper beam is disposed on the conductive contact and the signal transmission medium is pressed from the upper side by the upper beam. Then, the upward displacement of the signal transmission medium by the contact portion provided in the lower beam of the conductive contact is suppressed. However, this requires a work of inserting the signal transmission medium between the lower beam and the upper beam of the conductive contact, and thus there is a problem that the connection workability of the signal transmission medium is not good.

Therefore, the signal transmission medium can be easily placed without being obstructed by the conductive contact or the like with the inside of the main body housing completely opened. In addition, the open / close lid member in the closed state is easily moved by, for example, a fingertip and inserted between the first beam and the second beam, so that a signal is transmitted from one side of the first and second beams. A pressure contact force applied to the transmission medium is received on the other side of the first and second beams via the opening / closing lid member, and as a result, the displacement of the signal transmission medium is suppressed, and the signal transmission medium and the conductive material are electrically conductive. The electrical connection state with the contact is stably maintained.

  In the present invention, one of the first beam and the second beam in the conductive contact may be provided with a contact portion that contacts one surface of the signal transmission medium.

The terminal portion of the signal transmission medium F is placed on the main body housing 11 while being rotated to the open position raised from the main body housing 11. The opening / closing lid cover 12 after the signal transmission medium F is placed on the main body housing 11 is rotated to the closed position so as to be pushed down toward the front portion of the connector as shown in FIG. Has been made.

  The main body housing 11 of the electrical connector 10 is formed of an insulating member having a hollow frame shape, and the main body housing 11 is elongated along the lateral width direction of a signal transmission medium (FPC or FFC) F. It is formed to extend in a shape. Hereinafter, the lateral width direction of the main body housing 11 is referred to as a “connector longitudinal direction”. Further, the plane including the surface of the printed wiring board B described above is defined as a “horizontal plane”, a direction parallel to the “horizontal plane” is defined as “horizontal direction”, and a direction orthogonal to the “horizontal plane” is defined as “vertical direction”. A direction perpendicular to the “connector longitudinal direction” in the “horizontal plane” is referred to as a “connector longitudinal direction”.

  And the main body housing 11 is made into the structure where the front side area | region (right side area | region of FIG. 9) in the connector front-back direction was open | released upwards, and comprised the bottom face of the open front side area | region. On the provided medium receiving surface 11a, the terminal portion of the signal transmission medium (FPC, FFC, etc.) F described above is placed from above.

Medium guide convex portions 11b and 11b for alignment are provided. The medium guide convex portions 11b and 11b are configured to be fitted with engaging concave portions Fa and Fa formed by cutting out at both end portions in the connector longitudinal direction of the signal transmission medium F. When the transmission medium F is placed on the medium receiving surface 11a of the main body housing 11, the entire signal transmission medium F is aligned in the connector longitudinal direction and the connector longitudinal direction. Thus, since the effect | action which latches the signal transmission medium F by the structure by which the medium guide convex part 11b and the engagement recessed part Fa fit is obtained, the tensile holding strength of the signal transmission medium F can be raised.

  Further, each medium guide convex portion 11b described above is opposed to a temporary medium holding portion 11c that is lightly fitted to the upper surface side of a signal transmission medium (FPC, FFC, or the like) F aligned by the medium guide convex portion 11b. It is provided to do. The medium temporary holding portion 11c is formed of a claw-like member arranged so as to protrude from the upper surface of the signal transmission medium F placed on the main body housing 11, and the claw-like member places the signal transmission medium F on the upper surface. The signal transmission medium F is temporarily held by pressing lightly from the side. Further, the upper surface side of the temporary medium holding portion 11c is formed on an inclined surface having a guiding function, and a part of the signal transmission medium F abuts on the inclined surface, whereby a signal directed from the upper side to the lower side is formed. The placing operation of the transmission medium F is performed without any trouble. Further, when the signal transmission medium F is lowered to a predetermined placement position, the medium temporary holding portion 11c operates so as to protrude from the upper surface of the signal transmission medium F as described above, so-called fitting. You can get a click feeling.

  The opening / closing lid cover (opening / closing lid member) 12 has rotating shafts 12a, 12a at both ends in the connector longitudinal direction, and these rotating shafts 12a, 12a are in the connector longitudinal direction of the main body housing 11. The pivot cover 12 is pivotally supported by the bearings 13 and 13 provided at both end portions thereof, so that the entire opening / closing lid cover 12 is centered on the pivot shafts 12a and 12a. 2) and a closed position (see FIG. 4).

  Here, the bearing portions 13, 13 according to the present embodiment are configured to be integrally formed with hold-downs 14, 14 attached to both end portions of the main body housing 11 in the connector longitudinal direction. At the lower end edge of each hold-down 14, that is, the end edge placed on the printed wiring board B described above, a connection leg plate 14a extending in a substantially horizontal direction is bent at a substantially right angle over a plurality of bodies. . Each of the connection leg plates 14a is provided so as to protrude outward from both end edges in the connector longitudinal direction, and the connection leg plates 14a are placed at appropriate positions on the printed wiring board B. In this state, soldering is performed, ground connection is performed, and the entire connector is fixed.

  In addition, the opening / closing lid cover (opening / closing lid member) 12 according to the present embodiment is formed by bending a thin plate-like metal member into an appropriate shape, and ends of both sides of the opening / closing lid cover 12 in the connector longitudinal direction. Side edge plates 12b, 12b, which cover the main body housing 11 and the hold down 14 from the outside, are provided on the edge portion so as to form a flange wall shape. These side end plates 12b and 12b are provided so as to extend toward the center of rotation of the opening / closing lid cover 12, and the above-described rotation ends of the side end plates 12b and 12b are provided at the end portions on the extending side. The moving shafts 12a, 12a are provided so as to protrude toward the inner side in the connector longitudinal direction.

  On the other hand, as described above, each of the bearing portions 13 and 13 provided integrally with the holddowns 14 and 14 is formed with a through hole into which the rotating shafts 12a and 12a are inserted in a loosely fitted state. Yes. The through hole of the bearing portion 13 is formed in a long hole shape extending substantially along the connector longitudinal direction, and the opening / closing lid including the rotating shaft 12a along the long hole shape of the bearing portion 13. The entire cover (opening / closing lid member) 12 is configured to be movable substantially in the connector front-rear direction.

  And the long hole shape of the through-hole of the bearing part 13 at that time is formed so as to have a relatively large diameter at both end portions in the extending direction of the through-hole (substantially the front-rear direction of the connector). A middle portion connecting the large-diameter portions at both ends in a substantially horizontal direction is formed to have a relatively small diameter. On the other hand, the rotating shaft 12a of the opening / closing lid cover (opening / closing lid member) 12 described above has a large-diameter portion and a small-diameter portion alternately in the circumferential direction with respect to the long hole shape of the through hole of the bearing portion 13 described above. It has an irregular cross-sectional shape. The large-diameter portion of the rotating shaft 12a can be loosely fitted only to the large-diameter portions formed at both ends of the bearing portion 13 described above, and is formed in the middle portion of the bearing portion 13 in the extending direction. The small-diameter portion (the elongated extending portion) cannot be fitted, and the small-diameter portion of the rotating shaft 12a can be loosely fitted to both the small-diameter portion and the large-diameter portion of the bearing portion 13. It has become.

  Here, when the small diameter portion of the rotating shaft 12a is loosely fitted to the small diameter portion of the bearing portion 13, the connector can be moved in the longitudinal direction of the connector as shown in FIGS. The lid cover (opening / closing lid member) 12 is limited to the case where the lid cover (opening / closing lid member) 12 is rotated to the closed position along the main body housing 11. In this state, the small diameter portion of the rotation shaft 12 a is the small diameter of the bearing portion 13. The connector can be moved in the longitudinal direction of the connector along the upper and lower edges of the portion, but cannot be rotated due to the presence of the large-diameter portion of the rotating shaft 12a.

  Thus, the opening / closing lid cover (opening / closing lid member) 12 can be moved in the front-rear direction of the connector only when it is in the closed position with respect to the main body housing 11, and the front initial position shown in FIG. When the rotary shaft 12a is loosely fitted to the large-diameter portions at both ends of the bearing portion 13, the rotary shaft 12a is included. The entire lid cover 12 is configured to be rotatable.

  Here, as described above, when the opening / closing lid cover (opening / closing lid member) 12 is moved from the front initial position (see FIG. 12) toward the rear pushing position (see FIG. 14), An insertion protrusion 12c provided at the rear end portion (left end portion in FIG. 16) is guided by an insertion guide portion 14b provided on the hold down 14 side. Specifically, as shown in FIGS. 15 and 16, the inner edge of the hold-down 14 in the connector longitudinal direction extends above the insertion protrusion 12 c of the open / close lid cover 12. The insertion guide part 14b is provided in the middle position of the inner side edge part of the hold down 14 so as to protrude downward.

  The insertion guide portion 14b provided in the hold down 14 is formed of a claw-like member projecting toward the opening / closing lid cover (opening / closing lid member) 12 side, and the insertion protrusion plate of the opening / closing lid cover 12 by the claw-like member. By making contact with the portion 12c from above, the open / close lid cover 12 is moved rearward (leftward in FIG. 16) while being pushed downward, particularly at the rear end position shown in FIG. The main body housing 11 is accommodated inside. Details of the accommodation state will be described later.

  On the other hand, as described above, when the rotating shaft 12a is moved to the large-diameter portions provided at both end portions of the bearing portion 13, the rotating shaft 12a becomes rotatable. The entire opening / closing lid cover (opening / closing lid member) 12 can be rotated together with 12a. Accordingly, the open / close lid cover 12 in this case rotates between an open position raised from the main body housing 11 as shown in FIG. 2 and a closed position arranged along the main body housing 11 as shown in FIG. However, when the opening / closing lid cover 12 is in the rear pushing position (see FIG. 14), it cannot be rotated by the lock portion.

  That is, the lock portion provided corresponding to the opening / closing lid cover (opening / closing lid member) 12 includes a locking projection 14 c provided at the front end portion of the hold-down 14 and the rotation side end of the opening / closing lid cover 12. The engagement hook portion 12d provided on the edge portion, and when the opening / closing lid cover 12 in the closed position is moved to the rear pushing position (see FIG. 14), the engagement hook portion on the opening / closing lid cover 12 side. 12d is engaged with the locking projection 14c on the hold-down 14 side from below, so that the opening / closing lid cover 12 is held in a fixed position so that it cannot be rotated. .

  Furthermore, a plurality of conductive contacts 15 made of a thin plate-like metal member having an appropriate shape are mounted inside the main body housing 11. Each of the conductive contacts 15 is arranged in a multipolar shape with an appropriate interval pitch in the connector longitudinal direction inside the main body housing 11, and each of the conductive contacts 15 is either for signal transmission or for ground connection. As a matter of fact, it is mounted on a conductive path (not shown) formed on the printed wiring board B by solder bonding.

  The conductive contacts 15 are mounted by being inserted into the main body housing 11 described above, and each of the conductive contacts 15 is mounted on a signal transmission medium (FPC or FPC) placed and set on the main body housing 11. FFC and the like) are arranged at positions corresponding to F wiring patterns (not shown). The wiring patterns formed on these signal transmission media F are obtained by arranging signal transmission conductive paths (signal line pads) or shield conductive paths (shield line pads) at appropriate pitch intervals.

  Each of the conductive contacts 15 is composed of a pair of elongated beam members extending substantially in parallel along the connector front-rear direction (the left-right direction in FIG. 11), which is the direction in which the signal transmission medium (FPC, FFC, etc.) extends. A first beam (lower beam) 15a and a second beam (upper beam) 15b are provided. The first beam 15a and the second beam 15b are disposed in the internal space of the main body housing 11 so as to face each other at an appropriate interval in the vertical direction in the figure. 15b are integrally connected by a connecting column beam 15c extending in the vertical direction in the figure at the rear end portion in the extending direction of the beams 15a and 15b.

  At this time, the connecting column beam 15c is formed of a narrow plate-like member, and both the beams 15a and 15b described above from the connecting column beam 15c are on the front side in the connector longitudinal direction (right side in FIG. 11). It is configured to extend in a cantilevered direction.

  The second beam (upper beam) 15b of both the beams 15a and 15b described above is inserted into the main body housing 11 so as to be fixed. On the other hand, the first beam (lower beam) 15a is attached in a state where the rear end portion in the connector longitudinal direction is fixed to the main body housing 11 as described above. The portion extending in a holding shape is configured to have elastic flexibility. The portion of the first beam 15a extending to the front side is configured to be swingable about the connecting column beam 15c or the vicinity thereof as the center of rotation, and the first beam 15a at that time Is swung in the vertical direction within the plane of FIG.

  A wiring pattern (signal transmission) formed on the lower side of the signal transmission medium (FPC or FFC or the like) F described above is formed at the front end (right end in FIG. 11) of the first beam (lower beam) 15a. The contact convex portion 15a1 connected to either the conductive path or the shield conductive path is provided so as to form an upward protruding shape in the figure. Further, a substrate connecting portion 15a2 that is solder-connected to a conductive path (not shown) formed on the printed wiring board B is provided at the rear end portion (left end portion in FIG. 11) of the first beam 15a on the rear side. It is provided so as to protrude toward the left side of FIG.

  On the other hand, between the first beam (lower beam) 15a and the second beam (upper beam) 15b, a beam intervening piece portion 11d constituting a part of the main body housing 11 is formed. Has been. The beam intervening piece portion 11d is formed with a concave space portion opened toward the front side (the right side in FIG. 11), and as shown in FIG. When the lid cover (opening / closing lid member) 12 is moved to the backward pushing position, the insertion protrusion 12c of the opening / closing lid cover 12 is accommodated in the concave space of the beam interposing piece 11d.

  As described above, when the opening / closing lid cover (opening / closing lid member) 12 moves in the extending direction of the signal transmission medium (FPC, FFC, etc.) F (connector longitudinal direction), the insertion protrusion plate that is a part of the opening / closing lid cover 12 The portion 12c is configured to be inserted between the first beam (lower beam) 15a and the second beam (upper beam) 15b of the conductive contact 15, but more specifically, When the opening / closing lid cover 12 in the closed position is moved to the front initial position as shown in FIG. 11, the insertion projecting plate portion 12c of the opening / closing lid cover 12 is positioned at the tip of the first beam 15a (FIG. 11). Is located on the front side (right side in FIG. 11) of the second beam 15b.

  On the other hand, when the opening / closing lid cover 12 in the closed position is moved to the backward pushing position as shown in FIG. 13, the insertion protrusion 12c of the opening / closing lid cover 12 is connected to the first beam 15a and the second beam 15a. It is inserted into the inside of the concave space portion of the beam interposing piece portion 11d between the beam 15b. Thus, in a state where the opening / closing lid cover (opening / closing lid member) 12 is moved to the rear pushing position, the second beam (upper beam) 15b of the conductive contact 15 passes through the beam interposing piece 11d of the main body housing 11. Thus, a configuration is adopted in which a part of the opening / closing lid cover 12 can be contacted.

  At this time, the rotation shaft 12a of the opening / closing lid cover 12 is loosely fitted to the bearing portion 13, and the insertion protruding plate portion 12c is not in contact with the insertion guide portion 14b. It is relatively free to move. Therefore, as described above, due to the contact load received by the signal transmission medium (FPC, FFC, or the like) F from the first beam 15a of the conductive contact 15, the insertion protrusion 12c of the open / close lid cover 12 passes through the signal transmission medium F. The lid cover 12 moves so as to be pushed upward, and the contact load described above is transmitted to the second beam 15b of the conductive contact 15 when the cover cover 12 is pressed against the beam interposing piece 11d of the main body housing 11. It is made to be acceptable. As a result, the contact load is canceled out, and the load applied to the substrate connecting portion 15a2 of the conductive contact 15 is reduced.

  Further, the open / close lid cover 12 moved to the rear pushing position is held by the engagement hook portion 12d and the locking projection 14c constituting the lock portion. Further, the opening / closing lid cover 12 made of a thin plate-like metal member is bent and formed into an appropriate shape for its own reinforcement, but the opening / closing portion of the conductive contact 15 located immediately above the contact convex portion 15a1 is opened and closed. The lid cover 12 is configured to come into contact with the signal transmission medium F in a plane without being bent in order to prevent the signal transmission medium F from being bent upward due to contact load.

  According to the present embodiment having the above-described configuration, the opening / closing lid cover 12 as the opening / closing lid member is opened, and the signal transmission medium (FPC, FFC, etc.) F is placed on the main body housing 11, and then the opening / closing lid. A cover (opening / closing lid member) 12 is inserted between the first beam 15 a and the second beam 15 b of the conductive contact 15. Therefore, the signal transmission medium F is placed in a state where the inside of the main body housing 11 is completely opened, and the signal transmission medium F is easily placed without being obstructed by the conductive contacts 15 and the like. In addition, the signal transmission medium F is maintained on the original placement position without moving after being placed on the contact projection 15a1 of the conductive contact 15, and the first beam 15a and the second beam 15a of the conductive contact 15 are maintained. Since it is not inserted between the beam 15b and the wiring pattern formed on the signal transmission medium F and the contact convex portion 15a1 of the conductive contact 15, there is no occurrence of peeling of the plating, for example.

Therefore, the opening / closing lid cover 12 is reliably held at a fixed position after the movement, and the electrical connection state between the signal transmission medium F and the conductive contact 15 is more stably maintained.

  Further, in the present embodiment, the main body housing 11 is provided with a medium guide convex portion 11b for aligning the placement position of the signal transmission medium F, and the medium guide convex portion 11b is provided with the medium guide convex portion 11b. Since the medium temporary holding portion 11c that is lightly fitted to the aligned signal transmission medium F is provided, the signal transmission medium F is easily and reliably placed on the main body housing 11 by the medium guide convex portion 11b. In addition, the opening / closing lid cover (opening / closing lid member) 12 is smoothly and reliably moved with respect to the signal transmission medium F held by the medium temporary holding portion 11c of the medium guide convex portion 11b, and the signal transmission medium F Due to the locking action, the tensile holding strength of the signal transmission medium F is improved. Further, after the signal transmission medium F is placed on the contact protrusion 15a1 of the conductive contact 15, it is maintained at the original placement position without moving, and the first beam 15a and the second beam of the conductive contact 15 are maintained. Since it is not inserted between the beam 15b and the wiring pattern formed on the signal transmission medium F and the contact protrusions 15a1 of the conductive contacts 15, for example, plating peeling is prevented. .
