Description

  The present invention relates to an electrical connector configured to connect a board connection portion of a conductive contact on a printed wiring board.

  Generally, in various electric devices, electronic components and electronic circuits are electrically connected to a printed wiring board using an electrical connector. The connection between the electrical connector and the printed wiring board at that time is to bring the board connection portion of the conductive contact disposed inside the electrical connector to be used into contact with the conductive path of the printed wiring board. The connection between the connection portion and the conductive path of the printed wiring board is usually performed by so-called solder connection using a solder material.

  However, the solder connection performed in such a conventional electrical connector has the following various problems. First, there is a problem of dimensional error during the reflow process. In other words, the normal solder connection has a heating process called reflow, but the main part of the electrical connector is molded of resin, and in recent years, it has become a very small and thin shape due to the demand for lightness and shortness. For this reason, for example, the main body housing is deformed by reflow heat, which may cause a problem in dimensional accuracy by deviating from the required dimensions. In particular, since lead-free solder, which has been increasingly demanded in recent years, has a high melting point, the above-described problems of deformation and dimensional accuracy may become prominent. In particular, lead-free solder tends to have poor solder wettability compared to conventional lead-containing solder, so that the solder material does not spread appropriately and the solder connection between the conductive contact and the main printed wiring board is not possible. This may cause problems such as being unable to be performed or a decrease in strength after soldering.

  Furthermore, when solder connection is performed, the problem of soldering up, that is, the solder may rise more than necessary in the conductive contact, causing a short circuit of the conductive contact or a connection part between the conductive contact and the printed wiring board. In some cases, the amount of solder is reduced and peeling easily occurs. In addition, when such soldering reaches the contact portion of the conductive contact with the actuator or slider, the fixing operation of the actuator or slider becomes insufficient, or the contact between the signal transmission medium such as FPC and the conductive contact is insufficient. The pressure may change.

  Even when such a solder connection is made well, cracks occur in the solder material, which reduces the strength of the solder, peels off the conductive contacts, and causes poor conduction. A so-called flux increase occurs due to the flux contained in the cream, which may cause a problem of poor conduction.

  Here, a pair of fitting hook portions 16, 16 constituting the main body fixing means are provided on the bottom surface portion (lower surface portion in FIG. 2) of the main body housing 11 in the lateral width direction (longitudinal direction) of the main body housing 11. It is provided at both ends. Each of these fitting hook portions 16 is for holding the main body housing 11 on the printed wiring board 13, and from the bottom surface of the main body housing 11 to the lower side in the drawing, that is, on the printed wiring board 13 side. It is provided so as to protrude integrally.

  The pair of fitting hook portions 16 and 16 are formed of plate-like members extending in an elongated shape in the direction along the both end edges of the main body housing 11 (left and right direction in FIG. 2). Engagement protrusions 16a having a substantially arrow-tip shape in the longitudinal section are provided at the protruding end portion (lower end portion in the drawing) of the hook portion 16, respectively. A pair of engaging protrusions 16a, 16a provided on both the fitting hook portions 16, 16 are projected in an inward direction in the lateral width direction (longitudinal direction) of the main body housing 11.

These locking holes 13a and 13a are formed to have a hole shape penetrating the printed wiring board 13 in the plate thickness direction (vertical direction in FIG. 4), and each fitting on the main body housing 11 side described above. The fitting hook portion 16 is formed in a shape extending in an elongated shape along the longitudinal width direction (the left-right direction in FIG. 2) so that the fitting hook portion 16 can be inserted.

  When the fitting hook portions 16 and 16 provided on the main body housing 11 side are inserted into the locking holes 13a and 13a provided on the printed wiring board 13 side from the upper side in the figure, The protruding projecting portion of the tip side arrow tip forming portion that forms the engaging protrusion 16a of the fitting hook portion 16 is in a positional relationship in which it is pressed against the inner wall surface of the locking hole portion 13a. As a result, each of the fitting hook portions 16 slides downward in the figure while being elastically bent so as to be spread outwardly in the lateral width direction (longitudinal direction) of the main body housing 11. When the arrow tip shaped portion of the engaging portion 16a provided at the tip portion of the fitting hook portion 16 penetrates the locking hole 13a on the printed wiring board 13 side, the original inner side Returns to the position of elastically. As a result, the arrow-tip-shaped portion of the engaging portion 16a is pressed against the surface of the printed wiring board 13 on the bottom surface side (the lower surface side in the drawing), whereby each fitting hook portion 16 is printed. It is maintained in a state of being firmly locked to the wiring board 13.

  Thus, when both fitting hook parts 16 and 16 by the side of the main body housing 11 are made into the latching state with respect to the printed wiring board 13, the bottom face part (lower surface part of FIG. 2) of the said main body housing 11 will become The printed wiring board 13 is configured to be in close contact with the surface (the upper surface portion in the drawing), and the entire connector including the main body housing 11 is held in a fixed state with respect to the printed wiring board 13.

The portion 12b2 is configured to be pressed against the conductive path of the printed wiring board 13.

  That is, in the present embodiment, the board connection terminal portion (board connection portion) 12b2 provided at the connector rear end side portion (right end side portion in FIG. 2) of the fixed beam 12b is connected to the bottom surface portion ( It is formed so as to extend so as to reach a position on the lower side of the figure than the lower surface portion in FIG. As described above, when the main body housing 11 is held in close contact with the printed wiring board 13 by the fixing holding force generated between the fitting hook portion 16 constituting the main body fixing means and the locking hole 13a. The board connection terminal portion 12b2 of the fixed beam 12b is also pressed toward the printed wiring board 13 side. Then, the board connection terminal portion 12b2 of the fixed beam 12b at that time is pressed against a conductive path (not shown) on the printed wiring board 13 while being elastically bent, so that the electrical connection between the two is performed satisfactorily. It is configured to be

  At this time, particularly in the present embodiment, when the actuator 15 as the medium fixing means described above is rotated, the pressing cam portion 15a provided on the actuator 15 causes the fixed beam 12b of the conductive contact 12 to be It acts so as to press the lower side of FIG. 2, that is, toward the printed wiring board 13. The board connection terminal portion 12b2 of the fixed beam 12b is also pressed against the conductive path (not shown) on the printed wiring board 13 by the pressing force based on the turning operation of the actuator 15. In addition to the fixing and holding force by the fitting hook portion 16 and the locking hole 13a as the main body fixing means described above, electrical connection is made with a stronger acting force.

  As described above, the board connection terminal portion (board connection portion) 12b2 provided on the connector rear end side portion (right end side portion in FIG. 2) of the fixed beam 12b is the bottom surface portion (FIG. 2) of the main body housing 11. The bottom surface portion of the main body housing 11 (the lower surface portion in FIG. 2) is not further configured to reach the lower position in the drawing as in the case where it extends to a position substantially coinciding with the plane including the lower surface portion). Even in this case, when the actuator 15 as the medium fixing means is rotated, the pressing cam portion 15a provided on the actuator 15 causes the fixed beam 12b of the conductive contact 12 to move downward in FIG. It acts to push toward 13. Further, the rotation-side free end portion of the actuator 15 acts to press the board connection terminal portion 12b2 against the conductive path on the printed wiring board 13. The board connection terminal portion 12b2 of the fixed beam 12b is pressed against a conductive path (not shown) on the printed wiring board 13 by the pressing force based on the turning operation of the actuator 15 and is electrically connected. Connections are made.

  In addition, the fitting hook part 16 which comprises the main body fixing means in this embodiment can also be changed into other mechanical fixing means, such as a screw and a resin rivet. Further, the mechanical fixing means including the fitting hook portion 16 can be appropriately changed to other fixing means such as solder connection via a fixing bracket other than the mechanical one. In the present embodiment, two main body fixing means are provided at both end portions of the main body housing. However, in addition to the both end portions, the main body fixing means can be provided at the central portion or the like.

Due to the force, the board connection terminal portion 12b2 of the conductive contact 12 is pressed onto the conductive path of the printed wiring board 13 to be pressed. As a result, it is possible to electrically connect the conductive contact 12 with respect to the substrate connection terminal portion 12b2 without performing solder connection as in the prior art. As a result, the solder connection of the conductive contact 12 to the substrate connection terminal portion 12b2 can be achieved. Work becomes unnecessary.

  At this time, particularly in the present embodiment, the main body fixing means for holding the entire connector is configured as the mechanical fixing means including the fitting hook portion 16 and the locking hole portion 13a as described above. Thus, in addition to the need for solder connection of the board connection terminal portion 12b2 of the conductive contact 12, solder connection for fixing the main body housing 11 is also unnecessary, and the use of solder material for the entire electrical connector is completely eliminated. It is possible to solve the aforementioned solder connection problem.

Since the board connection terminal portion 12b2 is configured to be pressed against the conductive path of the printed wiring board 13, the electrical connection of the board connection terminal portion 12b2 of the conductive contact 12 is more reliably performed. ing.

  In addition, in the present embodiment, the board connection terminal portion 12b2 of the conductive contact 12 is formed so as to protrude further downward than the mounting surface of the main body housing 11 with respect to the printed wiring board 13, and thus on the printed wiring board 13. When the substrate connection terminal portion 12b2 of the conductive contact 12 is placed on the printed wiring board 13, the substrate connection terminal portion 12b2 of the conductive contact 12 is reliably elastically displaced. Accordingly, the electrical connection is more reliably performed.

As a result, the whole connector including the main body housing 21 is held in a fixed state with respect to the printed wiring board 23. ing.

  When the fixing and holding force of the whole connector is generated between the fitting hook portion 26 as the main body fixing means and the locking hole 23a in this way, the fixing beam of the conductive contact 22 described above is generated by the fixing and holding force of the main body fixing means. A board connecting terminal portion 22b2 provided as a board connecting portion on the connector rear end side portion (the right end side portion in FIG. 2) of 22b is configured to be pressed against the conductive path of the printed wiring board.

  That is, the substrate connection terminal portion (substrate connection portion) 22b2 provided on the fixed beam 22b of the conductive contact 22 described above reaches a lower position in the drawing than the bottom surface portion (shown lower surface portion) of the main body housing 21. The main body housing 21 is brought into close contact with the printed wiring board 23 by the fixing holding force generated between the fitting hook portion 26 constituting the main body fixing means and the locking hole 23a as described above. When held in a state, the board connection terminal portion 22b2 provided on the fixed beam 22b of the conductive contact 22 described above is pressed against the printed wiring board 23 side. Then, the board connection terminal portion 22b2 provided on the fixed beam 22b of the conductive contact 22 is pressed against the conductive path on the printed wiring board 23 while being elastically bent, thereby electrically connecting the two. Is configured to perform well.

  At this time, particularly in this embodiment, when the actuator (medium fixing means) 25 as the medium fixing means described above is slid and operated, the pushing protrusion 25a provided on the actuator 25 is used for the conductive contact 22 described above. The fixed beam 22b acts to press the printed wiring board 23 on the lower side in the figure. Then, due to the pressing force based on the slide movement operation of the actuator 25, the board connection terminal portion 22b2 provided on the fixed beam 22b of the conductive contact 22 is against the conductive path (not shown) on the printed wiring board 23. It can be pressed with a stronger force.

  As described above, the board connection terminal portion (board connection portion) 22b2 provided on the fixed beam 22b extends so as to reach a position on the lower side in the drawing with respect to the bottom surface portion (lower surface portion in the drawing) of the main body housing 21. Even if not, when the actuator (medium fixing means) 25 as the medium fixing means is slid, the pushing projection 25a provided on the actuator 25 causes the fixed beam of the conductive contact 22 described above. It acts to press 22b toward the printed wiring board 23 on the lower side in the figure. Then, due to the pressing force based on the slide movement operation of the actuator 25, the board connection terminal portion 22b2 provided on the fixed beam 22b of the conductive contact 22 is against the conductive path (not shown) on the printed wiring board 23. Thus, electrical connection is made.

  Also in the second embodiment having such a configuration, it is not necessary to perform solder bonding of the substrate connection terminal portion 22b2 of the conductive contact 22, and solder bonding for fixing the main body housing 21 is also unnecessary, so that the entire electrical connector is provided. Thus, almost the same operation and effect as the first embodiment described above can be obtained.

[Third Embodiment]
Further, in the third embodiment shown in FIGS. 13 to 18, the medium fixing means (actuator 35) erected on the connector rear end side (right end side in FIG. 14) is arranged on the rear side (right side in FIG. 14). The present invention is applied to an electrical connector 30 of a type that is turned so as to be pushed down toward the other side. That is, the electrical connector 30 according to the third embodiment differs from the electrical connector 10 according to the first embodiment described above in terms of the configuration related to the actuator and the conductive contact, and relates to other parts. The configuration is common to each other. Therefore, in the following description, the tenth-order code “1” is replaced with “3” for the configuration common to the above-described first embodiment, and the description is omitted. The means (actuator 35), the conductive contact 32, and the configuration related thereto will be described.

  First, the conductive contact 32 disposed inside the main body housing 31 has a configuration in which the movable beam 32a and the fixed beam 32b are integrally connected by the connecting column portion 32c. Among them, the fixed beam 32b is configured to have a short span length extending from the connecting support column 32c to the rear side (right end side in FIG. 14), and the rear end portion of the connector as in the above-described embodiments. Different from those having long span lengths extending to

  The movable beam 32a disposed on the upper side of the fixed beam 32b in the drawing extends to the rear end portion of the connector (the right end portion in FIG. 14) so as to curve in a substantially arc shape toward the lower side of the drawing. 32a2. The curved distal end portion (lower end portion in FIG. 14) of the actuated portion 32a2 provided on the movable beam 32a is configured so that a part of the conductive contact 32 is formed as a separate part inside the actuator 35 as the medium fixing means. It arrange | positions so that the board | substrate connection terminal part (board | substrate connection part) 32b2 attached to may be contacted.

  That is, the actuator (medium fixing means) 35 is constituted by a substantially plate-like member extending in the width direction (longitudinal direction) in the width direction (longitudinal direction) at the rear end portion of the main body housing 31. Shaft portions (not shown) protruding outward are provided at both ends in the longitudinal direction). Both shaft portions are engaged with engaging portions 31c and 31c provided at both end portions in the lateral width direction (longitudinal direction) of the main body housing 31 so as to be freely rotatable and vertically and horizontally movable. As a result, the entire actuator 35 is made rotatable, and the actuator 35 is prevented from falling off the main body housing 31.

  And the opening and closing which comprises the rotation side free end part (upper end part of FIG. 14) of the said actuator 35 from the "connection cancellation | release position" of the state which the whole actuator 35 stood upright like FIGS. By applying an appropriate turning operation force by the assembling worker to the operation portion 35b, the whole is pushed down toward the rear side, and is in a state where it is tilted substantially horizontally as shown in FIGS. It is configured to be rotated to the “connection operation position”.

  Here, the actuator (medium fixing means) 35 has a pressing cam portion 35a for swinging the movable beam 32a described above. The pressing cam portion 35a is disposed at the lower end portion of the actuator 35 shown in FIG. 16 that is maintained at the above-described “connection release position” (see FIG. 16), and extends horizontally on the printed wiring board 23. It is formed from a substantially meniscus member.

  Then, the opening / closing operation part 35b of the actuator 35 in the “connection release position” is rotated by pushing down the entire actuator 35 toward the “connection operation position” (see FIG. 17) while the assembly operator holds it by hand. Is performed, the pressing cam portion 35a that has been lying in a horizontally long state is raised as shown in FIG. 17, and the upper end of the raised pressing cam portion 35a is turned on. The portion is configured to press-contact the actuated portion 32a2 provided on the rear end side of the movable beam 32a described above so as to push up from the lower side in the figure. The actuated portion 32a2 of the movable beam 32a is displaced so as to be lifted upward in the drawing by the pushing-up action of the pressing cam portion 35a at that time, and accordingly, the opposite side to the actuated portion 32a2 (connector front end side). The terminal contact convex portion 32a1 provided on the bottom is pushed downward.

  The rising height of the pressing cam portion 35a is maximized immediately before the “connection operation position” in which the actuator (medium fixing means) 35 is the final rotation position, and only a small angle from the maximum rising height position. In the “connection operation position” which is the position after the rotation (see FIGS. 17 and 18), with respect to the signal transmission and ground conductive paths (not shown) formed in the signal transmission medium 34, Any one of the terminal contact convex portion 32a1 and the terminal contact convex portion 32b1 is brought into pressure contact, and thereby an electrical connection is made.

  On the other hand, as described above, the substrate connection terminal portion (substrate connection portion) 32b2 arranged inside the actuator (medium fixing means) 35 is a position corresponding to the conductive contact 32 arranged inside the main body housing 31. The actuator 35 is press-fitted into a groove formed in the actuator 35 and attached so as to rotate integrally with the rotation operation of the actuator 35. However, the actuator 35 is bent so as to form a substantially U-shape. It has a cross-sectional shape. A contact portion 32b3 which is bent at a substantially right angle and extends to contact the operated portion 32a2 of the movable beam 32a described above is provided at the tip end portion (left end portion in FIG. 14) of the board connection terminal portion 32b2. A contact portion 32b4 is provided on the opposite side of the substrate connection terminal portion 32b2 from the contact portion 32b3 so as to be elastically deformable. The contact part 32b3 provided on the board connection terminal part 32b2 is configured to always contact the actuated part 32a2 of the movable beam 32a when the actuator 35 is stopped or rotated. .

  That is, the contact portion 32b3 provided in the substrate connection terminal portion (substrate connection portion) 32b2 described above is connected to the operated portion 32a2 of the movable beam 32a even when the actuator (medium fixing means) 35 is rotated. The actuator 35 is configured to be slid while maintaining the contact state, and the actuator 35 is either “connection release position” (see FIGS. 13 to 16) or “connection action position” (see FIGS. 17 to 18). Regardless of whether the contact portion 32b3 of the substrate connection terminal portion 32b2 is always in contact with the operated portion 32a2 of the movable beam 32a.

  Further, the substrate connection terminal portion (substrate connection portion) 32b2 is, as shown in particular in FIG. 17, when the actuator 35 is tilted to the “connection operation position”, the bottom surface of the substrate connection terminal portion 32b2 shown in the drawing. The contact part 32b4 located on the side is configured to be pressed against the conductive path (not shown) on the printed wiring board 33 described above. The contact portion 32b4 is pressed against the printed wiring board 33 in this manner based on the holding action of the main body fixing means with respect to the main body housing 31.

  That is, also in the present embodiment, a pair of fitting hook portions 36, 36 constituting the main body fixing means are provided on the bottom surface portion of the main body housing 31, and the fitting is performed on the printed wiring board 33 side. Locking holes 33a and 33a corresponding to the hooks 36 and 36 are provided so as to constitute the main body fixing means. When the fitting hook portions 36, 36 on the main body housing 31 side are inserted into the locking holes 33a, 33a on the printed wiring board 33 side from the upper side in the figure, both fittings on the main body housing 31 side are performed. The hook portions 36 and 36 are maintained in a locked state with respect to the printed wiring board 33, and as a result, the entire connector including the main body housing 31 is held in a fixed state with respect to the printed wiring board 33. It is configured as follows.

  Thus, when the fixing and holding force of the whole connector is generated between the fitting hook portion 36 as the main body fixing means and the locking hole 33a, the connector of the conductive contact 32 described above is generated by the fixing and holding force of the main body fixing means. The contact part 32b4 of the board connection terminal part 32b2 provided in the rear end part (right end part in FIG. 14) is configured to be pressed against the conductive path of the printed wiring board 33.

  That is, the contact portion 32b4 of the board connection terminal portion (board connection portion) 32b2 provided at the connector rear end side portion of the conductive contact 32 described above is disposed so that the tip protrudes from the actuator 35. When 35 is tilted to the “connection operation position”, it extends so as to reach a position below the bottom of the main body housing 31 (the bottom surface in the figure). The main body housing 31 is placed on the printed wiring board 33 in a state where the actuator 35 is tilted to the “connecting position” by the fixing holding force generated between the fitting hook portion 36 constituting the fixing means and the locking hole 33a. When the substrate connection terminal portion 32b2 provided on the fixed beam 32b of the conductive contact 32 is held in close contact with the printed circuit board 3, And thus it pressed against the side. As a result, the contact portion 32b4 of the board connection terminal portion 32b2 of the fixed beam 32b is pressed against the conductive path on the printed wiring board 33 while being elastically bent, and thereby the electrical connection between the two is favorably performed. It is configured as follows.

  Also in the third embodiment having such a configuration, it is not necessary to perform solder bonding of the substrate connection terminal portion 32b2 of the conductive contact 32, and solder bonding for fixing the main body housing 31 is also unnecessary, so that the entire electrical connector is provided. The use of the soldering material with respect to the above eliminates the use of the solder material, so that substantially the same operations and effects as in the first and second embodiments described above can be obtained.

  In particular, in the present embodiment, the contact portion 32b4 of the substrate connection terminal portion (substrate connection portion) 32b2 constituting a part of the above-described conductive contact 32 rotates integrally with the actuator (medium fixing means) 35. In this case, since the board connection terminal portion 32b2 is configured to slide while contacting the conductive path (not shown) of the printed wiring board 33, for example, the board connection terminal portion 32b2 of the conductive contact 32 is used. It is possible to remove dust and the like caught between the contact portion 32b4 and the conductive path of the printed wiring board 33. Furthermore, the oxide film formed on each surface of the contact portion 32b4 of the substrate connection terminal portion 32b2 of the conductive contact 32 and the conductive path of the printed wiring board 33 is removed, and the electrical connection is performed well.
