Description

  The present invention relates to a female connector that connects to a male connector having a fixed contact portion formed at a narrow pitch, and a connector connection mechanism that connects a fixed contact portion of a male connector and a movable contact portion of a female connector arranged at a narrow pitch.

  In recent years, in connectors where multipolarization and miniaturization are desired, in order to narrow the pitch in the arrangement direction of a plurality of contacts attached to the insulating housing, each contact formed by punching a conductive metal plate into a narrow width is used as the insulating housing. The contact is bent in the punching direction and elastically contacted with the fixed contact portion of the male connector. However, if the contact width is less than 1 mm, the contact becomes unstable because a predetermined elasticity cannot be obtained with respect to the amount of bending at the time of elastic contact and sufficient contact pressure cannot be obtained. It was a thing.

  Therefore, conventionally, in a female connector that needs to arrange a large number of contacts at a narrow pitch, a contact formed by punching a conductive metal plate is supported on an insulating housing so as to bend in a direction perpendicular to the punching direction. The cross-sectional second moment is increased, a larger bending stress is generated, and elastic contact is made with the fixed contact portion of the male connector with sufficient contact pressure (Patent Document 1).

  The conventional female connector 100 will be described with reference to FIG. 9. The female connector 100 includes an insulating housing 102 mounted on the printed wiring board 101, and a vertical plane (plane parallel to the paper surface) in the insulating housing 102. The plurality of contacts 103 are positioned and fixed, and the slider 104 is detachably attached to the insulating housing 102.

  Each contact 103 is formed by punching a conductive metal plate and integrally forming a movable contact portion 103a facing the insertion recess 102a of the insulating housing 102 and a leg portion 103b solder-connected to the circuit pattern on the printed wiring board 103. Yes. The plurality of contacts 103 are insulated along the arrangement direction parallel to each other and perpendicular to the paper surface in accordance with a terminal lead portion (fixed contact portion) of a flexible flat cable (hereinafter referred to as FPC) 110 inserted into the insertion recess 102a. It is fixed to the housing 102.

  Thus, each contact 103 is left in the punched conductive metal plate without being bent, and is supported in the insulating housing 102 so as to be elastically deformed in a direction orthogonal to the punching direction. 103a is elastically contacted with a large contact pressure with the terminal lead portion of the FPC 110 inserted into the insertion recess 102a. Further, since the width in the arrangement direction of the contacts 103 is the thickness of the conductive metal plate, it can be arranged in the insulating housing 102 at a narrow pitch so as to coincide with the terminal lead portions of the FPC 110 arranged at a narrow pitch. .

  On the other hand, when an FPC 110 or a flexible printed circuit board (hereinafter referred to as FFC) corresponding to a male connector is inserted and connected to the insertion recess 102a of the female connector 100 in which the contact pressure of each contact 103 is increased in this manner. Since the contact pressure is received from a large number of contacts 103, the insertion force is large, and the flexible FPC 110 and FFC cannot be inserted and connected as they are. Therefore, in the female connector 100 connected to a flexible male connector such as the FPC 110 or the FFC, when inserting the male connector into the insertion recess 102a, the slider 104 is retracted from the insertion recess 102a so as to open a predetermined gap. A ZIF (zero insert force) structure is employed in which the slider 104 is later advanced to the insertion recess 102a and connected with a predetermined contact pressure.

  However, the electrodes for driving the display of recent plasma display panels and liquid crystal display panels have an extremely narrow pitch of about 0.2 mm between the electrodes, and these electrodes are connected as fixed contact portions, or these Similarly, contacts on the female connector side connected to the terminal lead portion of the FPC drawn out from the electrodes of the FPC need to be arranged at an extremely narrow pitch.

  According to the configuration of the conventional female connector 100, the width of the contacts 103 in the arrangement direction can be set to the thickness of the conductive metal plate, so that the pitch can be reduced to some extent. If the contacts are formed by punching out from a thin conductive metal plate of about 0.1 mm in order to arrange the contacts, the plate-like flat surface of the contact is curved when the male connector is inserted and connected. There is a risk that the plastic deformation will not function as an elastic contact.

  In addition, when forming a contact that punches a conductive metal plate with a narrow width and bends in the punching direction, there is a limit to the width that can be punched with respect to the thickness of the conductive metal plate. Thus, the contacts with a minute width of about 0.1 mm arranged by punching are punched from a thin conductive metal plate, and as described above, sufficient contact pressure cannot be obtained. Therefore, contacts formed by any of the conventional methods are not suitable for contacts arranged at an ultra-narrow pitch, and connection with electrodes arranged at an ultra-narrow pitch drawn out from a display panel or the like is not performed once. It was necessary to connect to the female connector after expanding.

  In addition, in a female connector for connecting a contact to a terminal lead portion such as a flexible FPC 110 or FFC, it is necessary to have a ZIF structure provided with a slider 104 that is movable with respect to the insulating housing 102. There is a problem that an extra process is required, the structure is complicated, and the size of the entire connector is increased.

  The present invention has been made in consideration of the above-described conventional problems. In order to arrange the contacts in the insulating housing at a narrow pitch, the fixed contact of the male connector can be achieved even if the width of the contacts in the arrangement direction is narrow. It is an object of the present invention to provide a female connector and a connector connection structure that are elastically contacted with a sufficient contact pressure and have a stable connection.

  It is another object of the present invention to provide a connector connection structure that connects to a flexible FFC or FFC without employing a ZIF structure.

In order to achieve the above object, a female connector according to claim 1 is an insulating housing, a shell fixed to the insulating housing, and an insertion recess for inserting an insert plate portion of the male connector is formed between the insulating housing, Each of the contacts includes a plurality of contacts that are attached to the insulating housing in parallel with the insertion direction of the male connector. Is a female connector that elastically contacts a fixed contact portion formed at an opposing portion of the insert plate portion sandwiched between the shell, and the fixed contact portion of the male connector and the contact are electrically connected,
Each contact is attached by fixing the first fixing portion and the second fixing portion at two places with different longitudinal directions to the insulating housing, and the fixed beam portion fixed at both ends by the first fixing portion and the second fixing portion is: A portion bent to the insertion recess side and facing the insertion recess of the fixed beam portion is a movable contact portion.

  When the insert plate portion of the male connector is inserted into the insertion recess, the fixed beam portion that contacts the movable contact portion facing the insertion recess at the portion where the fixed contact portion of the insert plate portion faces and bends toward the insertion recess is defined as the bending direction. Bend in the opposite direction. Since both ends of the fixed beam portion are fixed to the insulating housing by the first fixed portion and the second fixed portion, axial stress is generated along with bending stress in the fixed beam portion, and even if the contact has a small cross-sectional area. A large reaction force is generated against the insert plate portion. Therefore, even if a thin conductive metal plate is punched into a narrow width to reduce the cross-sectional area in order to reduce the pitch, the movable contact portion of the contact is in sufficient contact with the fixed contact portion of the insert plate portion. Contact with pressure.

  In the female connector according to the second aspect, the fixed beam portion is bent so that the contact portion of the movable contact portion with which the insert plate portion inserted into the insertion recess contacts gently with respect to the insertion direction of the male connector. It is characterized by.

  Since the insert plate portion inserted into the insertion recess contacts the movable contact portion that is gently inclined with respect to the insertion direction, the bending stress generated in the fixed beam portion of the contact is small, and the amount of bending in the bending direction is small. No plastic deformation and less fatigue

The connector connecting structure according to claim 3 is a male connector having a ceramic substrate having a plurality of fixed contact portions formed on the surface at a narrow pitch, an insulating housing, and the male connector fixed to the insulating housing. Shells in which insertion recesses for inserting ceramic substrates are formed, and each of them is formed in an elongated strip shape, and an intermediate movable contact portion of the elongated strip shape is faced to the insertion recess to be parallel to the insertion direction of the male connector. A ceramic substrate comprising a female connector having a plurality of attached contacts, and the movable contact portion of each contact being sandwiched between the shell when the ceramic substrate of the male connector is inserted into the insertion recess of the female connector The connector that elastically contacts the fixed contact portion formed at the opposite portion of the male connector and electrically connects the fixed contact portion of the male connector and the contact of the female connector. A data connection structure,
Each contact of the female connector is attached by fixing the first fixing portion and the second fixing portion at two places with different longitudinal directions to the insulating housing, and both ends are fixed by the first fixing portion and the second fixing portion. The portion is bent toward the insertion concave portion, and the portion facing the insertion concave portion of the fixed beam portion is a movable contact portion that elastically contacts the fixed contact portion of the male connector.

  When the ceramic substrate of the male connector is inserted into the insertion recess, the fixed beam that bends toward the insertion recess is brought into contact with the movable contact portion facing the insertion recess at the portion where the fixed contact portion of the ceramic substrate faces, and the direction opposite to the bending direction Bend to. Since both ends of the fixed beam portion are fixed to the insulating housing by the first fixed portion and the second fixed portion, axial stress is generated along with bending stress in the fixed beam portion, and even if the contact has a small cross-sectional area. A large reaction force is generated against the ceramic substrate. Therefore, in order to reduce the pitch, even if a thin conductive metal plate is punched into a narrow width to make the cross-sectional area smaller, the movable contact portion of the contact is not fixed to the fixed contact portion of the ceramic substrate. Contact with.

  According to a fourth aspect of the present invention, the male connector is a plug that is connected to a terminal of a flexible printed circuit board or a flexible flat cable, and is flexible to a plurality of conductive patterns drawn from each fixed contact portion on the surface of the ceramic board. The terminal lead portions of the printed circuit board or the flexible flat cable are electrically connected to each other.

  Since the ceramic substrate that is inserted into the insertion recess and elastically contacts the plurality of contacts is a hard substrate, a flexible printed circuit board or a flexible flat cable can be connected to the female connector without providing a ZIF structure.

  The connector connection structure according to claim 5 is characterized in that the terminal lead portion of the flexible printed circuit board or flexible flat cable and the conductive pattern formed on the surface of the ceramic substrate are electrically connected by an anisotropic conductive adhesive. To do.

  In the step of positioning the conductive pattern formed on the surface of the ceramic substrate and the terminal lead portion so as to face each other, and heating and pressurizing via an anisotropic conductive adhesive, both are electrically connected. Since the ceramic substrate is excellent in heat resistance and has a small thermal expansion coefficient, the ceramic substrate is not deformed in the thermocompression bonding process, and the conductive pattern and the terminal lead portion are not displaced.

  The connector connection structure according to claim 6, wherein the contact portion of the movable contact portion with which the ceramic substrate inserted into the insertion recess contacts is gently inclined with respect to the insertion direction of the male connector. Is bent.

  Since the ceramic substrate inserted in the insertion recess contacts the movable contact portion that is gently inclined with respect to the insertion direction, the bending stress generated in the fixed beam portion of the contact is small, and the amount of bending in the bending direction is small. No deformation and less fatigue.

  According to the first aspect of the present invention, in order to arrange the contacts in the insulating housing at an extremely narrow pitch, even if the contacts are formed by thinly punching from a thin conductive metal plate, the contacts are fixed contacts of the male connector. Since it is elastically contacted with a sufficiently large contact pressure, the contact resistance is low and electrical connection is ensured.

  Therefore, a female connector is connected to a male connector having a fixed contact portion formed on the insert plate portion with an ultra-narrow pitch of about 0.1 mm, and the contacts are electrically connected without increasing the pitch of the fixed contact portion. Can do.

  According to the second and sixth aspects of the invention, the contact is not plastically deformed, and even if the insertion and removal of the insert plate portion and the ceramic substrate is repeated, the contact is less likely to be fatigued and the contact has durability. it can.

  According to the third aspect of the present invention, in order to arrange the contacts in the insulating housing at an extremely narrow pitch, even if the contacts are formed by thinly punching from a thin conductive metal plate, the contacts are fixed contacts of the male connector. Since it is elastically contacted with a sufficiently large contact pressure, the contact resistance is low and electrical connection is ensured.

  Therefore, even for a male connector with a fixed contact portion formed on the ceramic substrate with an ultra-narrow pitch, the female connector is directly connected without increasing the pitch, and each contact is securely connected to the fixed contact portion. Can be made.

  According to the invention of claim 4, since the flexible printed circuit board or the flexible flat cable can be connected to the female connector without adopting the ZIF structure using the slider movable with respect to the insulating housing, the structure of the female connector is small. Simplify.

  According to the invention of claim 5, even when the conductive pattern is also drawn out from the fixed contact portion formed at a narrow pitch at a narrow pitch, the terminal lead portions of the flexible printed circuit board or the flexible flat cable are respectively positioned, All the conductive patterns can be reliably electrically connected to the opposing terminal lead portions without short-circuiting adjacent conductive patterns only by heating and pressurizing via the anisotropic conductive adhesive.

  Moreover, since the ceramic substrate is excellent in heat resistance and has a small coefficient of thermal expansion, an anisotropic conductive adhesive that requires a heating step can be used for connection between the conductive pattern and the terminal lead portion. In addition, it is possible to remove the unnecessary flexible printed circuit board or flexible flat cable by reheating the connection part between the conductive pattern and the terminal lead part, so the ceramic board suitable for connection with the female connector is replaced. Without being replaced by another flexible printed circuit board or a flexible flat cable.

  Hereinafter, the socket 1 according to an embodiment of the present invention and the connector connection structure for connecting the plug 2 connected to the terminal of the FPC 110 to the socket 1 are shown in FIG. The description will be made with reference to FIGS.

  In the present embodiment, a socket 1 corresponding to a female connector includes an insulating housing 3, a shell 4 that covers the flat side (upper surface side) of the insulating housing 3, and a plurality of contacts 8 that are integrally supported by the insulating housing 3, It consists of nine. The insulating housing 3 is made of, for example, a heat resistant insulating plastic material such as PPS (polyphenylene sulfide) and a pair of side walls 32 and 32 erected on both sides in the longitudinal direction of the rectangular frame 31. The rectangular parallelepiped hollow space surrounded by the rectangular frame 31 serves as a contact accommodating chamber 5 that movably accommodates fixed beam portions 81 and 91 (described later) of the contacts 8 and 9. Yes. The height of the side wall 32 is slightly higher than the height of the ceramic substrate 21 described later of the plug 2, and the distance between the pair of side walls 32, 32 is slightly longer than the longitudinal width of the ceramic substrate 21. An insertion recess 6 for loosely fitting the ceramic substrate 21 is formed between the shell 4 and the rectangular frame 31 spanned between 32.

  The shell 4 is formed by punching a conductive metal plate into an elongated strip shape, and both sides in the longitudinal direction are folded back downward in a U shape along the side walls 32, 32 of the insulating housing 3, and are fixed to the insulating housing 3. . As described above, the gap between the pressing plate portion 41 of the shell 4 covering the upper portion of the insertion recess 6 and the rectangular frame 31 while being fixed to the insulating housing 3 is substantially the same as the thickness of the ceramic substrate 21 of the plug 2. Therefore, in order to avoid interference with the terminal connection portion 110a of the FPC 110 fixed on the ceramic substrate 21, the rear side of the pressing plate portion 41 of the shell 4 is cut out in a rectangular shape along the longitudinal direction. . Further, the front end of the pressing plate portion 41 is bent at a right angle downward so as to cover the front surface where the insertion recess 6 opens, and covers the front side of the insertion recess 6.

  The plurality of contacts 8 and 9 are fixed to the insulating housing 3 by being molded integrally with the rectangular frame 31 when the insulating housing 3 is molded. Here, in order to arrange the contacts 8 and 9 at a pitch of 0.1 mm along the longitudinal direction of the insulating housing 3, the contacts 8 and the contacts 9 arranged at a pitch of 0.2 mm are arranged in a staggered manner. As shown in FIG. 4, the legs 84 of each contact 8 are fixed in a state of protruding rearward from the insulating housing 3 and the legs 94 of each contact 9 protruding forward from the insulating housing 3.

  Each contact 8 is a conductive metal plate having a spring property, such as phosphor bronze, and a thin metal plate having a thickness of 0.1 mm or less is punched into a narrow width of several hundreds μm, and a plurality of contacts 8 are integrally connected with a hoop material. As shown in FIG. 2, with the first fixed portion 82 at the tip and the second fixed portion 83 in the middle left on the same plane without being bent, the fixed beam portion 81 therebetween is angled upward. The base end side of the second fixing portions 83 and 93 is bent downward in a crank shape to form the leg portion 84.

  Each contact 9 is also punched out of the same conductive metal plate to the same width as that of the contact 8, and is bent in the same manner as the contact 8 while the plurality of contacts 9 are integrally connected with the hoop material. A first fixing portion 92, a mountain-shaped fixing beam portion 91, a second fixing portion 93, and a crank-shaped leg portion 94 are formed.

  The contacts 8 and 9 thus press-bent are cut at the tips of the first fixing portions 82 and 92 in a state where the base end side (the leg portions 84 and 94 side) is integrally connected to the hoop material. When the insulating housing 3 is molded, the second fixing portion 83 of the contact 8 and the first fixing portion 92 of the contact 9 are arranged on the rear frame portion of the rectangular frame 31, and the first fixing portion 92 of the contact 8 is arranged on the front frame portion. The first fixing portion 82 and the second fixing portion 93 of the contact 9 are insert-molded. Accordingly, the fixed beam portions 81 and 91 of the contacts 8 and 9 are supported by the insulating housing 3 so as to bend in the punching direction in a state where both ends are constrained.

  As shown in FIG. 2, the plurality of contacts 8 and the plurality of contacts 9 fixed integrally to the insulating housing 3 include a first fixing portion of the contact 8 in order to secure an insulating distance between the adjacent contacts 8 and 9. 82 and the second fixing portion 83 are fixed to the rectangular frame 31 at positions below the first fixing portion 92 and the second fixing portion 93 of the contact 9. However, the apex P of each movable contact part 85 and 95 which faces in the insertion recessed part 6 is made the same height by changing the gradient with respect to the front-back direction of the fixed beam part 81 and the fixed beam part 91 which were bent.

  In other words, the inclination of the fixed beam portion 81 of the contact 8 arranged on the lower side with respect to the front-rear direction is steeper than the fixed beam portion 91 of the contact 9, but the inclination of the fixed beam portion 81 from the second fixed portion 83 toward the apex P. Is bent so as to have a gentle inclination of at least 30 degrees or less with respect to the front-rear direction. In this way, the slopes of the portions of the mountain-shaped fixed beam portions 81 and 91 with which the ceramic substrate 21 of the plug 2 inserted into the insertion recess 6 abuts are made gentle so that the ceramic substrate 21 inserted in the front can be removed. The bending amount in the bending direction (direction orthogonal to the axial direction) received by the fixed beam portions 81 and 91 is small. As a result, plastic deformation does not occur, and both ends are fixed even when the bending amount is small. A large reaction force is generated from what is being done. On the other hand, when the inclination of the fixed beam portions 81 and 91 is a steep inclination of 30 degrees or more with respect to the front-rear direction, the component force in the bending direction of the fixed beam portions 81 and 91 received from the insertion force of the ceramic substrate 21 increases. As the frictional force increases, the amount of bending in the bending direction is large. For example, the fixed beam portions 81 and 91 bent in a mountain shape may be further bent in the bending direction and may be plastically deformed. Stops functioning.

  The contacts 8 and 9 formed integrally with the insulating housing 3 in a state of being integrally connected to the hoop material are formed by the leg portions 84 of the contacts 8 projecting from the rear and the leg portions 94 of the contacts 9 projecting from the front. At each end, the hoop material integrally connected to each other is cut, and the attachment of the contacts 8 and 9 to the insulating housing 3 is completed.

  The socket 1 configured as described above is configured such that the leg portions 84 and 94 of the contacts 8 and 9 and the end portion of the shell 4 folded downward along the side walls 32 and 32 of the insulating housing 3 are respectively printed wirings. Solder connection is made to the land pattern exposed at the corresponding portion on the surface of the substrate 30, the contacts 8 and 9 are electrically connected to the corresponding circuit pattern, and the insulating housing 3 is positioned and fixed on the printed wiring board 30. Implemented.

  The plug 2 to be a male connector is made of a ceramic substrate 21 formed of a glass-based ceramic material, an alumina-based ceramic material or the like as shown in FIGS. 7 and 8, and a conductor such as copper or silver on the bottom surface thereof. A plurality of fixed contact portions 22 formed along the front-rear direction, and a plurality of conductive patterns 23 drawn from the back of each fixed contact portion 22 to the surface side of the ceramic substrate 21 with the same conductive material as the fixed contact portion 22. It consists of.

  A slightly thicker front portion of the ceramic substrate 21 is an insert plate portion 21a that is inserted into the insertion recess 6 of the socket 1 and has an outer shape that loosely fits into the insertion recess 6. However, the longitudinal width is insulated. The width between the side walls 32 and 32 of the housing 3 coincides with an accuracy of at least less than 0.05 mm, and the fixed contact portion 22 and the contacts 8 and 9 are in exact contact with each other without being displaced.

  Further, a concave portion 21b in which the terminal connection portion 110a of the FPC 110 is disposed is formed on the plane side of the rear portion of the ceramic substrate 21, and a plurality of conductive patterns 23 are wired in the concave portion 21b. The protrusions projecting to both sides at the rear end of the ceramic substrate 21 are gripping portions 24 for holding the plug 2 in hand.

  The plurality of fixed contact portions 22 are arranged in the longitudinal direction of the ceramic substrate 21 so that the fixed contact portions 22 are opposed to and contact the plurality of contacts 8 and 9 arranged at a pitch of 0.1 mm along the longitudinal direction of the socket 1. Are formed at a pitch of 0.1 mm. In the present embodiment, since the fixed contact portion 22 and the conductive pattern 23 are formed with the same width using the same conductive material, a large number of narrow conductive paths are formed at a pitch of 0.1 mm from the bottom surface of the ceramic substrate 21 to the planar concave portion 21b. Of these, the part exposed to the bottom surface side is formed as the fixed contact part 22 and the part drawn out to the flat recess 21b is formed as the conductive pattern 23 in the same process.

  Therefore, the conductive pattern 23 with a pitch of 0.1 mm is exposed in the concave portion 21b of the ceramic substrate 21, and the terminal leads of the FPC 110 wired at the same pitch to the plurality of conductive patterns 23 exposed on the concave portion 21b. The parts 110b are electrically connected to each other. The connection between the two is performed by using an optical jig so that each conductive pattern 23 and the terminal lead 110b face each other, and then the terminal connection 110a of the FPC 110 where the terminal lead 110b is exposed and the ceramic. The recesses 21b of the substrate 21 are performed in a thermocompression bonding process in which heat and pressure are applied via an anisotropic conductive adhesive. Through this connection process, the plug 2 is connected to the terminal connection portion 110 a of the FPC 110, and the plurality of terminal lead portions 110 b are electrically connected to the fixed contact portion 22 through the conductive pattern 23 individually.

  When the plug 2 configured as described above is connected to the socket 1, as shown in FIG. 2, the insert plate portion 21a is inserted into the insertion recess of the socket 1 while holding the pair of gripping portions 24 of the plug 2 with fingers. Insert into 6. The insert plate portion 21a inserted into the insertion recess 6 abuts on the movable contact portions 85 and 95 of the contacts 8 and 9 protruding into the insertion recess 6 and moves the movable contact portions 85 and 95 along with the forward insertion. Push in the direction of the contact accommodating chamber 5.

  In the state shown in FIG. 3 in which the insert plate portion 21a of the plug 2 is completely inserted into the insertion recess 6 of the socket 1, the amount of bending of the movable contact portions 85 and 95 pushed into the contact housing chamber 5 is slight. Since both ends are fixed to the insulating housing 3 by the first fixing portions 82 and 92 and the second fixing portions 83 and 93, the plurality of conductive patterns 23 of the plug 2 and the movable contact portions 85 of the contacts 8 and 9 facing each other. , 95 at a high contact pressure, and the contacts 8 and 9 corresponding to the terminal lead portions 110b of the FPC 110 are electrically connected.

  Although the FPC 110 is formed of a flexible material, the FPC 110 is connected to a large number of contacts 8 and 9 through the hard ceramic substrate 21. Therefore, the terminal of the FPC 110 can be connected to the socket 1 that does not employ the ZIF structure. Further, since the conductive pattern 23 is wired on the ceramic substrate 21 having excellent heat resistance, a thermocompression bonding process is performed for connection between the conductive pattern 23 wired at a narrow pitch of 0.1 mm and the terminal lead portion 110b. The required anisotropic conductive adhesive can be used. Furthermore, without changing the connection structure between the socket 1 and the plug 2, the FPC 110 can be removed by heating the ceramic substrate 2 and the terminal connection part 110 a of the FPC 110, and can be replaced with another FPC or FFC.

  In the above-described embodiment, the shell 4 made of a metal plate is integrally fixed to the insulating housing 3 and the insertion recess 6 is formed. The shell 4 is formed integrally with the insulating housing 3 and the insulating housing 6 itself. The insertion recess 6 may be formed.

  The plug 2 having the ceramic substrate 21 may be connected to a terminal of a flexible flat cable (FFC) other than the FPC 110. Further, the ceramic substrate 21 is mounted with a chip component or the conductive pattern 23 is used as a lead frame. A ceramic substrate on which a semiconductor bare chip connected by wire bonding or the like is mounted may be used as a plug 2 connected to the socket 1.

  Furthermore, in the above-described embodiment, two types of contacts 8 and 9 are attached to the socket 1, but a socket in which one type of contact is attached at a narrow pitch may be used.

  The present invention is suitable for a socket connected to a plug in which a fixed contact portion is wired at a narrow pitch.
