It has the 2nd spring piece 8b which inclines so that it may leave | separate gradually from the root part 8a, and extends ahead, and the 2nd press part 8c bent at the front-end | tip of the 2nd spring piece 8b at the convex shape upwards . The second root portion 8a has a second convex portion 8d that is bent downward and convex.

  The first spring portion 7 and the second spring portion 8 are in a one-to-one correspondence with each other and are aligned in the front-rear direction A1. In the example of illustration, the 1st spring piece 7b is longer than the 2nd spring piece 8b, and the 1st press part 7c exists in a position higher in the up-down direction A2 than the 2nd press part 8c. Further, in the plurality of second spring portions 8, the second pressing portions 8c are arranged in a staggered manner by changing the length of the second root portion 8a, and the second convex portions 8d are also second Similar to the pressing portion 8c, a staggered arrangement is provided.

  On the other hand, the conductor film 16 has a relatively flexible insulating film 16a and a plurality of conductive paths 16b formed on the surface of the insulating film 16a in parallel and spaced apart from each other. The conductor film 16 has an intermediate portion attached to the upper surface of the substrate portion 15a of the spring member 15, both sides of the intermediate portion are wound so as to surround the first spring portion 7 and the second spring portion 8, and both end portions are substrate. By attaching to the lower surface of the part 15a, the spring member 15 is attached.

  The conductive path 16b is provided in one-to-one correspondence with the second spring portion 8 in the vertical direction A2. Each conductive path 16b extends along a portion from the second pressing portion 8c of the second spring portion 8 to the second root portion 8a via the second spring piece 8b. A portion corresponding to the second pressing portion 8c of the conductive path 16b forms a first contact portion 16c, and a portion corresponding to the second convex portion 8d forms a second contact portion 16d. The surface of the part corresponding to the 1st press part 7c among the insulating films 16a forms the cleaning part 16e.

  In addition, the positioning member 15b and 16f which penetrate the board | substrate part 15a and the insulating film 16a are formed in the contact member 5 surrounded by the conductor film.

  The connector C is assembled with a conductor film so that the first spring portion 7 and the second spring portion 8 are positioned in the first spring portion accommodating portion 4e and the second spring portion accommodating portion 4f, respectively. The encircling contact member 5 is accommodated in the contact member accommodating portion 4c of the housing 4, and the substrate portion 15a is fixed to the lower surface of the spring member fixing beam portion 4d by an appropriate means. At that time, the positioning holes 15b and 16f enter the positioning projection 4g provided on the lower surface of the spring member fixing bar 4d, and the contact member 5 surrounded by the conductor film is positioned. The contact member 5 surrounded by the conductor film is fixed by bonding the portion of the substrate portion 15a to the lower surface of the spring member fixing beam portion 4d, or by attaching the tip of the positioning protrusion 4g to the lower surface side peripheral portion of the positioning holes 15b and 16f. Or by welding.

  In this assembled state, the cleaning portion 16e and the first contact portion 16c of the contact member 5 surrounded by the conductor film protrude into the FPC insertion hole 4a, and the first base portion 7a, the substrate portion 15a, the first contact portion 5 of the contact member 5 The second base portion 8 a is substantially flush with the lower surface of the housing 4, and the second contact portion 16 d slightly protrudes downward from the lower surface of the housing 4.

  The connector C configured as described above is used by being mounted on a substrate 6 as shown in FIG. At that time, the second contact portions 16d of the connector C are arranged on the pads 6a on the substrate 6 in a one-to-one correspondence. Further, the connector C is fixed on the substrate 6 by tightening screws (not shown) through screw holes 4h and 6b provided in the connector C and the substrate 6, respectively. By this fixing, the second contact portion 16d of the connector C is pressed against the pad 6a on the substrate 6 and brought into contact conduction.

  In order to connect the FPC 1 to the connector C, the FPC 1 is inserted into the FPC insertion hole 4a. Then, the tip of the FPC 1 comes into contact with the cleaning portion 16e and pushes down the cleaning portion 16e against the spring force of the first spring portion 7. The cleaning portion 16e enters the lower surface of the FPC 1 and comes into contact with the pad 1a on the lower surface of the FPC 1 with a predetermined contact pressure by the spring restoring force of the first spring portion 7. When the FPC 1 is further inserted into the FPC insertion hole 4a in this state, the pad 1a of the FPC 1 slides on the cleaning portion 16e. As a result, foreign matters and contaminants adhering to the pad 1a are eliminated, and the pad 1a is cleaned. Since the cleaning portion 16e is made of a relatively flexible insulating film, there is little possibility that the pad 1a of the FPC 1 is damaged by this cleaning.

  Further, when the FPC 1 is inserted until the tip of the FPC 1 comes into contact with the abutting position 12 at the back of the FPC insertion hole 4a, the first contact portion 16c resists the spring force of the second spring portion 8 like the cleaning portion 16e. Pushed down. In this state, the first contact portion 16c comes into contact with the pad 1a on the lower surface of the FPC 1 with a predetermined contact force due to the spring restoring force of the second spring portion 8. As a result, the FPC 1 is electrically connected to the substrate 6 through the contact member 5. Here, the pad 1a of the FPC 1 contacts the first contact portion 16c after the foreign matter or the like is surely removed and cleaned by the cleaning portion 16e, so that a good electrical connection can be achieved.

  Further, the pressure member 3 is inserted into the pressure member insertion hole 4b to press the FPC 1 downward, the contact force between the first contact portion 16c and the pad 1a of the FPC 1, and the second contact portion 16d and the substrate. The contact force between the pads 6a on 6 is increased and the electrical connection between them is ensured. The pressure member 3 is held in a pressurized state by a pressure holding means (not shown) provided separately.

  In this way, by inserting and connecting the FPC 1 to the connector C, the device member 2 connected to the FPC 1 is provided with an inspection processing circuit (not shown) provided on the substrate 6 or another inspection processing via the substrate 6. It is electrically connected to an apparatus (not shown), and a display inspection of the device member 2 is performed.

  According to the connector described above, since the cleaning portion 16e is formed of a relatively flexible insulating film, the pad 1a of the FPC 1 slides on the cleaning portion 16e with a predetermined contact pressure without damaging the pad 1a of the FPC 1. As a result, adhering foreign matter and contaminants can be surely eliminated, and a good electrical connection can be achieved.

  Further, the plurality of first contact portions 16c, the second contact portions 16d, and the conductive paths 16b connecting the contact portions can be easily formed at a narrow pitch by patterning the conductor film 16. In addition, a plurality of first spring portions 7 and second spring portions 8 of the spring member 15 that apply a spring force to the cleaning portion 16e and the first contact portion 16c are also formed continuously on both sides of the substrate portion 15a. Therefore, it can be formed by punching in a simple and narrow pitch. Accordingly, it is easy to manufacture contact members and connectors having a narrow pitch multi-contact arrangement.

  In addition, since the plurality of first spring portions 7 and the second spring portions 8 of the spring member 15 that apply a spring force to the cleaning portion 16e and the first contact point 16c are independent of each other, By changing the length, plate thickness, plate width, etc. of the second spring portion 8, it is possible to give the cleaning portion 16e and the first contact point 16c an optimum spring force for foreign object removal and electrical connection, It is possible to reliably remove foreign matters, contaminants, and the like adhering to the pad 1a of the FPC 1 and to make a good electrical connection.

  Further, as shown in FIG. 5A, the second pressing portion 8c extends the conductive path 16b corresponding to the second spring portion 8 located at the relatively front portion to the front portion relatively long, while FIG. As shown, the second pressing portion 8c extends relatively short so as to terminate the conductive path 16b corresponding to the second spring portion 8 located at the rear portion so as to terminate at the rear portion. The interval between the existing conductive paths 16b can be designed wide. Therefore, it is possible to easily prevent an electrical short circuit between adjacent ones of the conductive paths 16b extending relatively long.

  In addition, although the case where the spring member 15 was formed with the metal material was demonstrated, the spring member 15 may be formed with another material, for example, a resin material. In addition, the first spring portion 7 corresponds to the second spring portion 8 on a one-to-one basis, but the first spring portion 7 corresponds to the plurality of second spring portions 8 so as to correspond to the second spring portion 8. One spring portion 7 may be formed wide.

  Further, the pressure member 3 is inserted into the pressure member insertion hole 4b of the housing 4 and the FPC 1 is pressed downward to increase the contact pressure with the first contact 16c. However, in that case, the pressure member insertion hole 4b of the housing 4 is also unnecessary.

  Moreover, although a part or all of the said embodiment may be described also as the following additional remarks, it is not restricted to the following.
