BACKGROUND ART Circuit boards used for electronic devices and the like have been required to have high density, and printed wiring boards and connectors such as FPCs for connecting these electric circuits to each other have also been required to be smaller and higher in density. For this reason, for example, in FPC etc., the external connection parts are alternately arranged in a zigzag to form a large number of external connection parts in a very small area with high density. Therefore, also in the connector into which such FPC is inserted, several terminal members are alternately arranged in a zigzag pattern corresponding to the external connection part of an FPC, and responding to densification has been performed (for example, refer patent document 1).

As a conventional structure of this kind of connector, a plurality of terminal members (contactors) contacting the external connection portions (contact terminals) of the FPC inserted into the housing are provided on one side of the housing of the connector. In addition, the connector is provided with a slider for connecting the external connecting portion of the FPC inserted in the housing to the terminal member provided in the housing. After the FPC is inserted into the housing, the slider is pushed in and the FPC is held in the housing, and the external connection portion of the FPC is connected to the terminal member in the housing.

In this way, when the arrangement of the external connection portions of the FPC is zigzag-shaped, the external connection portions are alternately positioned back and forth in the longitudinal direction alternately at one interval. Therefore, a plurality of terminal members arranged in the housing of the connector which connects to the external connection portions of these FPCs are also provided at intervals in the insertion direction of the FPC.

Moreover, one end side of the terminal member extends and protrudes outside the housing, and one end side of the terminal member is soldered and fixed to a conductive pad portion of a circuit board such as an electronic device.

However, in the structure of the conventional FPC connector described above, the terminal member disposed in the housing of the connector is adjacent to the terminal when the positional shift occurs in the housing at the time of insertion of the FPC due to the narrow pitch of the external connection portion of the FPC. There existed a problem that it might come in inferior contact with the external connection part of the FPC corresponding to the member.

In addition, in the case where the position shift occurs when the connector is mounted on the circuit board due to the narrow pitch between the conductive pad portions on the circuit board such as an electronic device, the solder pad of the terminal member extending out of the housing corresponds to the adjacent solder portion. There was a problem of wealth and missoldering

Therefore, in the present invention, the above-mentioned problem is solved, and the connector and the terminal member can be reliably contacted with the external connection part of the counterpart FPC which should originally contact the terminal member of the connector, thereby preventing the wrong contact with the adjacent external connection part. And a connector and a terminal member which can be reliably soldered with a conductive pad portion on a circuit board to which the soldering portion of the terminal member of the connector should be originally soldered, and can be prevented from being incorrectly soldered with an adjacent conductive pad portion. It aims to do it.

The hole portion (not shown) may be formed by punching. In this case, when the contact portion 2c and the soldering portion 2f are pressed into a thin shape, the thickness crushed into a previously formed hole portion escapes, so that the contact portion 2c and the soldering portion 2f are separated. It is easy to make thickness thin and it is performed with high precision.

In the drawing, the lead portions 2e and 3e at the rear ends of the first and second terminal members 2 and 3, which protrude outwardly of the housing 1, are formed on the circuit board 6; It is mounted on the conductive pad part 6a, and the soldering parts 2f and 3f and the conductive pad part 6a are soldered and fixed by the solder 7.

In this case, the tips of the soldering portions 2f and 3f are formed so that the thickness becomes thinner than the thickness of the lead portions 2e and 3e in the plate thickness direction, and the tips of the soldering portions 2f and 3f have a thickness. By being thin, the width dimensions of the soldering portions 2f and 3f that can be connected to the conductive pad portion 6a of the circuit board 6 even if the position shift occurs when installed on the circuit board 6. Because of the small size, the soldering portions 2f and 3f can be prevented from being erroneously soldered to the conductive pad portion 6a adjacent to the conductive pad portion 6a which should be originally soldered.

Moreover, since the said conductive pad part 6a is formed in rectangular shape, and the said soldering parts 2f and 3f extend and protrude along the longitudinal direction of the said conductive pad part 6a, the said soldering part 2f And the solder 7 soldered to 3f are widened in the longitudinal direction along the solder portions 2f and 3f formed in a shape having a long length in the formation direction of the conductive pad portion 6a, and thus the lead portion 2e. , 3e) can increase the soldering strength.

It is supposed to be.

Next, the operation of the connector having the above configuration will be described.

First, in the initial state shown in FIGS. 1 to 3, the lever 4 is in a state where the front end side stands up on the upper surface of the housing 1, and the opening 1a of the housing 1 is opened. It is in the state that became. In this state, the printed wiring board 5, which is the member to be connected, in the opening 1a of the housing 1 can be fitted and fixed.

In this state, the printed wiring board 5 as a member to be connected is inserted from the opening 1a of the housing 1. 5 and 6, the tip portion with the conductor pattern formed between the arm portions 2a and 2b of the first terminal member 2 and the arm portion of the second terminal member 3 is formed. It is held between 3a and 3b).

From this state, as shown in FIG. 5 and FIG. 6, when pressing the front end side opposite to the support shaft part 4b of the said lever 4, as shown in FIG. 5, the said lever 4 will support the said support. It rotates centering on the shaft part 4a. When the lever 4 is rotated, the oval-shaped sandwiching portion 4c provided at the base of the slit groove 4b is also rotated, and the upper end is the arm portion 2b of the first terminal member 2. By contacting and slidingly contacting the pressing portion 2d formed on the free end side of the side), an elastic force is generated in the arm portion 2b, and the lever 4 is held in the locked position.

At this time, the lower end of the clamping portion 4c presses the printed wiring board 5, which is the member to be connected, thereby causing the printed wiring board 5 to be mounted on the one arm portion 2a of the first terminal member 2. Is held between the contact portions 2c. At this time, the printed wiring board 5 is also held between the arm portions 3a and 3b of the second terminal member 3 at the same time.

At this time, the first and second terminal members 2, 3 are formed so that the elastic force is generated by opposing the pair of arm portions 2a, 2b, 3a, 3b in a substantially U shape and an approximately J shape. As a result, a certain clamping force is obtained. In this case, since the elastic force is generated in the direction orthogonal to the plate thickness direction of the metal plate, a strong elastic force is obtained.

According to the embodiment described above, the first and second terminal members 2 and 3 of the present invention are formed to be elastically deformable in a direction perpendicular to the plate thickness direction by punching a flat metal plate in the plate thickness direction. The contact portions 2c, 3c, and 3d are formed to protrude from the arm portions 2a, 3a, and 3b, and the tip portions of the contact portions 2c, 3c, and 3d are formed at the arm portions 2a and 3a, Since the thickness of the contact portion 2c, 3c, 3d is thinner than the thickness in the plate thickness direction of 3b), the printed wiring board 5, which is a member to be inserted into the connector, is made thinner. Even if this position shift occurs, the widths of the contact portions 2c, 3c, and 3d that can come into contact with the external connection portions (not shown) of the printed wiring board 5 are small, so that the contact portions 2c, 3c, and 3d False contact to an external contact adjacent to an external contact that must be in contact Moisture can be prevented.

In addition, since the contact portions 2c, 3c, and 3d are formed to protrude from the arm portions 2a, 3a, and 3b in the form of a mountain, the printed wiring board 5 is connected at the time of connection with the printed wiring board 5. It is possible to smoothly contact the external connection of the.

In addition, the first and second terminal members 2 and 3 are formed on the lead portions 2e and 3e, which extend and protrude out of the housing 1, to the conductive pad portions 6a of the circuit board 6, respectively. Since the solder portions 2f and 3f to be soldered are formed, the tip ends of the solder portions 2f and 3f are formed so as to be thinner than the thickness in the plate thickness direction of the lead portions 2e and 3e. Even if the tip ends of the soldering portions 2f and 3f are thin, the position shift occurs at the time of installation on the circuit board 6, the conductive pad portion 6a of the circuit board 6 and the conductive pad portion 6a. Since the width dimensions of the solderable portions 2f and 3f that can be connected are small, the soldering portions 2f and 3f are incorrectly soldered to the conductive pad portion 6a adjacent to the conductive pad portion 6a to be originally soldered. I can prevent it.

As described above, in the terminal member of the present invention, in the terminal member formed by punching a flat metal plate in the plate thickness direction, a connecting portion connectable to the mating side connecting portion of the mating connecting member is provided, and Since it is formed so that thickness may become thinner than the thickness of the plate thickness direction of the part except the tip of a connection part, even if the tip of a connection part becomes thin, even if it causes a position shift with respect to a mating member, the mating side of a mating member Since the width dimension of the connection part which can be connected with a connection part is small, it can prevent that a connection part is erroneously connected to the counterpart connection part adjacent to the counterpart connection part which should be originally connected.

And an arm portion formed to be elastically deformable in a direction perpendicular to the plate thickness direction, wherein the mating portion of the mating member is an external portion of the member to be connected, and the mating portion is a contact portion that can be in contact with the external portion of the member to be connected. The contact portion is formed to protrude from the arm portion, and the tip portion of the contact portion is formed so that the thickness becomes thinner than the thickness in the plate thickness direction of the arm portion. Even if the position shift occurs, since the width dimension of the contact portion that can be in contact with the external connection portion of the member to be connected is small, it is possible to prevent the contact portion from coming in erroneous contact with the external connection portion adjacent to the external connection portion that should be originally contacted.

In addition, since the contact portion is formed to protrude from the arm portion in the shape of a mountain, the external connection portion of the member to be connected can be smoothly contacted with the member to be connected.

In addition, since the arm portion is formed integrally with the terminal member by punching after forming the contact portion thin in the terminal member, even if there is an expansion protrusion in the protruding direction when the contact portion is made thin, punching processing is performed thereafter. Therefore, the precision of the protrusion height of a contact part can be raised.

In addition, the connector is formed to protrude from an arm portion formed to be elastically deformable in a direction perpendicular to the plate thickness direction of the plate-shaped metal plate, and the tip of the contact portion that is in contact with the external connection portion of the member to be connected has a thickness in the plate thickness direction. And a housing having an opening for inserting the printed wiring board and a lever pressurizing the printed wiring board to the terminal member. Since the external connection portion and the contact portion of the terminal member are brought into contact with each other, even when the printed wiring board is displaced when the printed wiring board is inserted into the housing, the contact portion of the terminal member that can be contacted with the external connection portion of the printed wiring board. Since the width dimension of is small, the external connection where the contact must It is possible to prevent erroneous contact with the adjacent external connecting portion.

In the method of manufacturing the terminal member, a thin metal contact portion is formed on the metal plate by pressing a portion of the plate-shaped metal plate in the plate thickness direction, and then the metal plate is plated in a state including the thin contact portion. By punching in the thickness direction, the arm part is elastically deformable in a direction perpendicular to the plate thickness direction, and when the arm part is punched, the contact part is punched at the same time as the arm part, so that the contact part is formed to protrude into the arm part. Even when there is an expansion protrusion in the protrusion direction when forming the contact portion, the punching processing of the contact portion is performed simultaneously with the arm portion, so that the accuracy of the protrusion height of the contact portion can be improved.

In addition, since the hole was formed by punching a flat metal plate, and then the vicinity of the hole was pressed in the plate thickness direction to form a thin contact portion on the metal plate. At this time, since the thickness crushed into the previously formed hole portion escapes, it is easy and precisely performed to reduce the thickness of the contact portion.

And a lead portion extending outwardly of the disposed housing, wherein the mating side connecting portion of the mating side member is a conductive pad portion of a circuit board, the connecting portion is a soldering portion soldered to a conductive pad portion of the circuit board, and the soldering portion It is formed in the lead portion, and the tip of the solder portion is formed to be thinner than the thickness of the lead portion in the plate thickness direction, so that even if a position shift occurs when installing on the circuit board, the conductive pad portion of the circuit board Since the width dimension of the solder | pewter part which can connect with and is small, it can prevent that a solder part is mis-soldered in the conductive pad part adjacent to the conductive pad part which should be originally soldered.

In addition, since the conductive pad portion is formed in a rectangular shape and the solder portion is formed by extending and extending in the longitudinal direction of the conductive pad portion, the solder to be soldered along the solder portion formed in a shape having a long length in the conductive pad forming direction. Since it is widened in the longitudinal direction, it is possible to increase the soldering strength.

Further, since an end portion is formed between the soldering portion and the lead portion, the solder to be soldered reaches the end of the upper surface along the thin portion, so that the soldering surface increases, and the soldering strength can be further increased.

In addition, since the lead portion is formed integrally with the terminal member by punching after forming the soldering portion thin in the terminal member, even if there is expansion protrusion in the protrusion direction when the soldering portion is thin, the punching processing is performed thereafter. The precision of the protrusion height of a soldering part can be raised.

In addition, the connector is formed in a lead portion formed to protrude out of the housing, and a plurality of terminal members are formed in parallel so that the tip of the solder portion to be soldered to the conductive pad portion of the circuit board is thinner than the thickness in the plate thickness direction of the lead portion. And a lever for pressing the printed wiring board inserted into the opening of the housing to the terminal member. The terminal member includes a housing for mounting the lead portion in the conductive pad portion of the circuit board. Since the contact portion which is in contact with the external connection portion is formed, when the printed wiring board connector is installed on the circuit board, even if the position shift occurs, the width dimension of the solder portion that can be connected to the conductive pad portion of the circuit board is small. That the solder pads are incorrectly soldered to the conductive pads adjacent to the conductive pads to be soldered. You can prevent it.

Further, in the method for manufacturing a terminal member, a thin soldering part is formed on the metal plate by pressing a portion of the flat metal plate in the plate thickness direction, and then the lead part is formed by extending and protruding out of the soldering part and the housing. Since the soldered portion was integrally formed in the lead portion by punching in the thickness direction, the soldering portion was punched out simultaneously with the lead portion even if the soldered portion was thinned, even if there was expansion protrusion in the protrusion direction. The accuracy of the height of the negative protrusion can be increased.

In addition, since the hole was formed by punching a flat metal plate, and then the vicinity of the hole was pressed in the plate thickness direction to form a thin solder portion on the metal plate. Since the thickness crushed into the previously formed hole portion escapes, it is easy and precisely performed to reduce the thickness of the solder portion.
