[Prior Art] Fig. 7 is a front view of an existing connector in a state in which an FFC or FPC is inserted, and Fig. 8 is a cross-sectional view taken along line C-C in Fig. 7. • The conventional electrical connector includes a housing 1 and a contact bar 2 fixed and supported by a terminal in the terminal mounting space formed by the connection I surface toward the inside of the housing, and the housing 1 is connected to the above The separating wall 9 is provided in such a manner that each of the spot bars 2 is crossed and not in contact. The component symbol 5 is a fixing portion of the terminal. The height of the separation wall 9 is set to ensure a gap larger than the thickness of the base body 3 of the FFC and the FPC between the inner wall of the terminal mounting space. The base body 3 of the FFC or FPC can be inserted into the contact rod 2 Between the inner wall 17 of the terminal mounting space, the contact bar 2 of the terminal and the conductive pad 4 of the FFC or FPC are electrically connected. Such an electrical connector is disclosed in Japanese Laid-Open Patent Publication No. 8-273 77-2. In the prior art, in order to reduce the height of the separation wall 9, a contact 8 which is adjacent to the space 3 of the FFC or FPC and which is adjacent to the contact point 8 has The relationship between each other. Therefore, when the contact pins 15 are mutually grown by the gaps 14 from the adjacent contacts 8 and are in contact with each other, there is a problem that a short circuit between the terminals occurs. Although the lead-free 1327798, which is imported into electrical parts in response to the environmental problems of the past and today, is connected to the electric power, it is especially important at the time. Shi Xizhi is plated for the week, the sex is the middle of the road, the short-loaded foil with the force or force and the sub-price end plus the low-cost application of the neighbor is made to be in the usual but necessary, the contactor is connected to observe The significant growth of the whiskers 15 to a length of 100 to 2 00 hinders the progress of lead-free plating of the electrical connectors and FFC, FPC surfaces. Therefore, in the conventional electrical connector, when tin plating is used to achieve lead-free, the contact points are grown at the contact 8 of the contact bar 2 and the substrate 3 of the FFC and the FPC, and the adjacent contact is made. The above-mentioned voids of the contact bars 2 between the rods 2 are generated and contacted, and there is a problem that the circuit is short-circuited. Further, in order to prevent this short circuit, there is also a problem of using gold plating which does not generate whiskers on the surface of the terminal, and in this case, there is a problem that the price of the pad connector becomes expensive. The present invention has been made in view of the above problems, and an object thereof is to provide a stress which is often applied by holding a lead-free plated FFC or FPC such as tin plating, so that even when a tentacles are grown, it is not adjacent. An electrical connector that causes a short circuit between the contact plates. (Means for Solving the Problem) The electrical connector of the present invention has an opening into which a base body of a flexible flat cable (FFC) or a flexible printed circuit board (FPC) can be inserted in an insulating case elongated in the width direction. A plurality of terminals mounted in the terminal mounting space formed by the opening toward the inside of the casing, and having a separating wall between the terminals in such a manner that the adjacent terminals are not in contact with each other, wherein the distance between the front end of the separating wall and the inner wall of the casing is set It is smaller than the thickness of the substrate of FFC or FPC. In the case of inserting the FFC or FPC, the insulating portion between the conductive pads of the FFC or FPC is brought into close contact with the elongated separation wall, so that the terminals and the conductive pads of the FFC or FPC are present in the space where the surroundings are closed. 1327798 According to the present embodiment, when the tentacles are grown by the elongated tap points which are in close contact with the FFC and FPC insulating portions which are centered on the contact points of the FFC and the FPC, the contact points are not caused and abutted; point. That is, the space in which the FEC 'FPC inserted into the electrical connector of the electrical connector is in contact with the tip end of the terminal, and the gap between the peripheral wall and the FFC and the FPC substrate is closed, and the space is φ plugged, and the direction is centered on the contact point. The front and back are respectively 200; the close contact of am or more does not cause the effect of abutment when the contact grows the tentacles. Therefore, there is an advantage that the surface of lead-free and FFC, FPC can be plated at low cost. The electrical connector of the present invention is characterized in that the use portion and the thinned front end are formed so as not to be in close contact with the insulating portion even when the width of the insulating portion between the FFC pads is narrow. According to the present embodiment, in most cases, when the resin wall is injection-molded, the inflow of the molten resin is also caused by poor inflow, and the thinned front end of the shape of the separated wall has a narrow width even when the FFC and the FPC are narrow. In the small electrical connector, there is also the effect of extending to the insulating portion. Further, the electrical connector of the present invention is characterized by: or a higher material of the FPC material to form a separation

Off-wall, there may be advantages in that tin plating which is short-circuited by a contact bar or a contact is used for the base end of the terminal thickening separation wall or the base of the FPC is formed by the separation formed on the conductive pad, and has no advantage. . In addition, the insulation separation wall between the pads is surely only at least by the hardness ratio of the FFC wall, and the FFC 'FPC 1327798 . ' FPC is more accurate than the FPC shape or extension of the FPC FPC. In the state in which the electrical connector is inserted, the front end of the elongated separation wall is eaten into the FFC and the insulating portion, and the insulating portion is plastically deformed or elastically deformed to achieve the adhesion between the separation wall and the insulating portion. Further, the electrical connector of the present invention is characterized in that the separation wall is formed of at least a material having a lower hardness than the material of the FPC, and the front end of the elongated separation wall is crushed and plasticized in a state where the FFC is inserted into the electrical connector. Deformation or elastic deformation, in order to more reliably achieve the adhesion between the FFC, FPC edge and the separation wall. φ is such that the material hardness of the elongate separation wall is made harder or softer than that of the FFC, and the FFC and FPC are inserted into the electrical connector state, and the front end of the elongate separation wall is eaten into the insulation portion of the FFC or FPC. When the long separation wall itself is elastically or plastically deformed, even if the size of the elongated wall is smaller than the amount of deformation, the insulation portion can be closely contacted. In addition, the electrical connector of the present invention is characterized in that a partition wall is formed by a member different from the casing, and the original function of the casing can be used as a priority. The material is used in the casing portion, and will be used with FFC and FPC. A material having a poor adhesion of the insulating portion is preferred for use in the separation wall. [Embodiment] Hereinafter, each embodiment of the present invention will be described with reference to Figs. (Embodiment 1) Figs. 1 and 2 show an electrical connector according to Embodiment 1 of the present invention. Fig. 1 is a front view, and Fig. 2 is a cross-sectional view taken along line A-A of Fig. 1. The electrical connector is formed by resin molding into a rectangular shape 1327798 » « · \ - block insulative housing 1 ' and a plurality of terminals 10 respectively mounted on the housing 1 by the fixing portion 5 . The terminal 10 has a joint portion 13 joined to a circuit board (not shown) by lead-free soldering or the like. The case 1 is formed by molding an insulating resin into a box shape, and is formed by an opening 16 as a contact hole, a wall portion 17 extending from the inside thereof, and a staggered and non-contacting with the adjacent terminal 10. The separation wall 9 separated in a manner forms an internal cavity 18'. The terminal 1 has a contact bar 2 having a curvature near the opening 16 and being substantially bent to 180 degrees, and the contact 8 is made by the spring 'φ It is arranged to abut against the wall portion 17. The terminal 10 is mainly formed of a resilient copper alloy, and has a affinity for soldering on the surface thereof to prevent rust, and is a tin-plated person for environmental problems of lead-free. The partition wall 9 integrally formed with the casing 1 has an elongated separation wall 6 whose base end is thicker than the front end and which is gradually thinner toward the center of the inner cavity 18 and elongated and has a triangular cross section. The distance t between the end portion 7 and the wall portion 17 before elongating the separation wall 6 is formed to be 0 smaller than the thickness tl of the FCC and FPC base 3 of Fig. 3 . The FCC or FPC inserted into the electrical connector of the present configuration, as shown in Fig. 3, is a raw material of a polyacrylamide, polyethylene terephthalate or vinyl acetate which is an insulating resin. The base 3 having a thickness t1 is fixed to a lead-free conductive pad 4 which is made of a copper foil or a thin copper plate and is tin-plated on the surface. Fig. 4 shows a state in which the FCC and the FPC are inserted into the electrical connector of the present configuration as seen from the front. Fig. 5 is a cross-sectional view taken along line B_B of Fig. 4. 1327798 The FCC, FPC base 3 inserted from the opening 16 of the housing 1 toward the bottom surface 12 is pressed against the 'FCC' FPC base 3 by the pressing force of the resilient contact rod 2 while being inserted. The conductive pad 4 is subjected to a predetermined pressure between the wall portion 17 of the casing 1 which is successively abutted by the contact 8 - the direction of the inner cavity 18 toward the bottom surface 12 and the vicinity of the bottom surface 12 Stop the insertion at the specified location. The contact 8 is used to prevent the FCC and the FPC substrate 3 from falling off from the electrical connector, and electrical conduction with the circuit substrate is achieved through the conductive pad 4. Similarly, at the time of insertion, the elongated separation wall 6 formed integrally with the casing 1 made of a material harder than the FCC and the FPC base 3 is abutted against the insulating portion 11' of the FCC and the FPC while the FCC and FPC substrates are simultaneously formed. (3) Insertion occurs when plastic deformation or elastic deformation occurs, and after the FCC and FPC base 3 reach the predetermined position, the state in which the elongated separation wall 6 is eaten into the FCC and the FPC base 3 is maintained. As a result, the insulating portion 11 of the FCC and the FPC is wrapped in the shape of the elongated separation wall 6 as shown in Fig. 4 to be swelled to maintain the adhesion. According to the cross-sectional view of Fig. 5, the contact between the FCC and the FPC base 3 and the elongate separation wall 6 is maintained at a distance of 0.2 mm or more along the insertion direction of the FCC and the FPC, and the contact 8 is considered. The wall made of an insulating resin is surrounded by four sides other than the traveling direction of the FCC and the FPC. Therefore, even if the whiskers 15 of the contacts 8 are grown up to the point where the observation is the largest 200 μm (= 0.2 mm), the short circuit between the adjacent terminals can be prevented. Further, the cross section of the elongate separation wall 6 is formed in a triangular shape, not only for the base body 3 which is easy to be eaten into the FCC or the FPC, but also because the space between the terminals 1 is reduced as the casing 1 is miniaturized and thinned. In the electrical connector, that is, -10- 1327798, when the insulating portion 11 of the FCC and the FPC is narrow, the elongated separation wall 6 does not easily lie on the conductive pad 4 and is easily adhered to the insulating portion 11. Further, the cross section of the elongate separation wall 6 is formed into a triangular shape in order to easily cause the molten resin to flow into the thin portion □ of the end portion 7 of the elongate separation wall produced by the resin molding method without causing a shape defect. (Embodiment 2) FIG. 6 shows an electrical connector according to Embodiment 2 of the present invention, and the same reference numerals are given to the same portions as Embodiment 1. The second embodiment differs from the first embodiment in that the material of the elongated separation wall 6 formed integrally with the casing 1 is made of a material softer than the base 3 of FCC or FPC. According to this configuration, when the FCC and the FPC are inserted into the electrical connector, the front end portion 7 of the soft elongated separation wall 6 is elastically deformed or plastically deformed by the surface of the FCC or FPC base 3 to be in close contact with the FCC'FPC base 3 After the insertion of the FCC and the FPC, the insertion of the FCC and the FPC is maintained at a distance of 0.2 mm or more in the insertion direction of the FCC' FPC, and the contact 8 is formed of an insulating resin. It is configured to surround four sides other than the traveling direction of FCC and FPC. Therefore, in the same manner as in the first embodiment, it is possible to obtain an effect of preventing short-circuiting between adjacent terminals due to the whiskers 15 which are grown by the contacts 8. Further, by forming the cross section of the elongated separation wall 6 into a triangular shape, the front end 7 of the elongated separation wall can be easily deformed by the contact with the base body 3 of the FCC and the FPC. Further, in the above embodiments, the "elongation separation wall 6 is integrally formed with the casing 1, but it is important to maintain the plurality of terminals 10, -11 - 1327798 as the casing 1 and to maintain the conductive pads 4 with FCC and FPC. In the case where the electrical conduction is originally functional, a method in which the elongated separation wall 6 is not formed integrally, but is formed by separate members and joined. That is, the case 1 is made of a material suitable for the original function of the known electrical connector, and the elongated separation wall 6 is made of an insulating resin harder than the base 3 of the FCC or FPC, or a soft insulating resin. 'Does not change the performance of the electrical connector to prevent short-circuiting of adjacent terminals caused by the whiskers. According to the pad connector of the present invention, even if the tentacles are grown from the contacts of the terminals and the conductive pads of the FCC or FPC, there is no effect of short-circuiting with adjacent terminals or contacts, so that the terminals and the FCC can be used. The use of inexpensive tin plating on the surface plating of FPC contributes to the lead-free promotion of the industry.
