In the connector of Patent Document 1, since the cleaning body is arranged in the case, the dust removed from the mounting board remains in the case. Therefore, when the mounting board is repeatedly inserted and removed, dust enters the vicinity of the connection portion between the connector terminal and the mounting board terminal. Moreover, the connector of patent document 1 is not set as the structure which can remove suitably the adhesive deposit | attachment adhering to the mounting board. Here, the sticky deposit is a member having viscosity unlike dust. Such adhesive deposits also cause poor contact between the connector terminals and the mounting board terminals. The occurrence of poor contact includes immediate occurrence and occurrence with time. Occurrence with time means that curing progresses slowly over a long period of time and sudden contact failure occurs one day.
The connector of Patent Document 2 is not configured to satisfactorily remove sticky deposits attached to the mounting board.
The connector of Patent Document 3 is not configured to be able to remove dust and adhesive deposits originally attached to the mounting board.

  The objective of this invention is providing the connector which solves the subject mentioned above.

  The connector of the present invention has a case in which an insertion port of the mounting board is formed, a terminal of the mounting board that is inserted from the insertion port of the case, a terminal that is connected at multiple points, and protrudes into the insertion port of the case, A first contact means made of an elastic body that contacts the mounting boat inserted from the insertion port and removes dust adhering to the mounting board and prevents intrusion of dust from the insertion port; And a second contact means made of an elastic body having an acute angle portion for removing an adhesive deposit adhered to the mounting board.

  According to the present invention, dust and adhesive deposits can be removed, and the terminals of the mounting board and the terminals of the connector can be favorably connected over time.

(B) It is a side view which shows the terminal of a connector roughly.

  A connector according to an embodiment of the present invention will be described. However, the present invention is not limited to the following embodiment. In addition, for clarity of explanation, the following description and drawings are simplified as appropriate.

  The connector 1 is installed on a motherboard or the like of an electronic device (not shown). As shown in FIG. 1, the connector 1 includes a case 2, terminals 3, first contact means 4, and second contact means 5.

  Case 2 is made of resin or the like. In the case 2, an insertion portion 21 into which the mounting board 6 (FIG. 2) is inserted is formed, and an insertion port 211 is formed at an upper opening edge of the insertion portion 21. The length of the insertion portion 21 in the short direction is a length L1 slightly longer than the thickness Y (FIG. 2) of the mounting board 6. The terminals 3 are arranged on the inner surface of the insertion portion 21 so as to correspond to the terminals 61 (FIG. 3) of the mounting board 6 to be inserted.

  The terminal 3 is multipoint connected to the terminal 61 of the mounting board 6 inserted from the insertion slot 211 of the case 2. For example, the terminal 3 is formed with a slit or a plurality of protrusions so as to form a plurality of connecting portions with the terminal 61 of the mounting board 6.

  As shown in FIG. 2, the first contact means 4 protrudes into the insertion port 211 of the case 2, contacts the mounting board 6 inserted from the insertion port 211, and removes dust adhering to the mounting board 6. While removing, it prevents the intrusion of dust from the insertion port 211. That is, the first contact means 4 is provided so as to face the insertion port 211 of the case 2 so as to sandwich the surface on which the terminal 61 of the mounting board 6 to be inserted is placed. The first contact means 4 is disposed above the terminal 3 disposed in the insertion portion 21 of the case 2. The distance X between the first contact means 4 facing each other is narrower by about 0.5 mm than the thickness Y of the mounting board 6. And the protrusion 41 which protrudes toward the insertion port 211 of case 2 is continuously formed in the upper end edge of the 1st contact means 4 in order to narrow the space | interval X of the 1st contact means 4 which faces each other. Has been. The protruding portion 41 is formed thin from the base portion toward the tip portion so as to be easily deformed in the insertion and extraction directions of the mounting board 6. The first contact means 4 has a length substantially equal to the length L2 of the longitudinal side of the insertion slot 211 of the case 2. The first contact means 4 is made of a deformable elastic body such as rubber. Therefore, when the mounting board 6 is inserted from the insertion port 211, the protrusions 41 of the first contact means 4 are deformed in the insertion direction of the mounting board 6, and the terminals 61 of the mounting board 6 are arranged. Contact is made across the entire length of the surface. As a result, the dust adhering to the mounting board 6 is removed before the insertion portion 21, that is, in a region outside the insertion portion 21 of the case 2. Moreover, since the protrusion part 41 of the 1st contact means 4 is deform | transforming and is contacting the surface in which the terminal 61 of the mounting board 6 is arrange | positioned, dust penetrate | invades into the insertion part 21 of the case 2 from the outside. Can be prevented.

  As shown in FIG. 2, the second contact means 5 is provided in the first contact means 4 and has an acute angle portion 51 that removes the adhesive deposits adhered to the mounting board 6. That is, the second contact means 5 is provided on the side surface on the insertion portion 21 side of the first contact means 4 so as to correspond to the terminal 61 of the mounting board 6 to be inserted. That is, a plurality of second contact means 5 are arranged for each terminal 3 of the connector 1 in the longitudinal direction of the first contact means 4. Therefore, the second contact means 5 is also disposed above the terminal 3 disposed in the insertion portion 21 of the case 2. The second contact means 5 has a triangular shape when viewed from the front, and one apex portion is disposed upward. The top portion is the acute angle portion 51 described above. The length of the bottom side of the second contact means 5 is substantially equal to the width dimension of the terminal 61 of the mounting board 6. The distance Z between the second contact means 5 facing each other is narrower by about 0.5 mm than the distance X between the first contact means 4 facing each other, as shown in FIG. The second contact means 5 is made of a deformable elastic body such as rubber. Therefore, when the mounting board 6 is inserted from the insertion port 211, the acute angle portion 51 of the second contact means 5 comes into contact with each terminal 61 of the mounting board 6. As a result, the adhesive deposit adhered to the terminal 61 of the mounting board 6 is scraped off in the a and b directions at the acute angle portion 51 of the second contact means 5 as shown in FIG. Of course, the dust adhering to the terminal 61 of the mounting board 6 is also scraped off.

  Such a connector 1 can reduce the removal of dust adhered to the mounting board 6 by the first contact means 4 and the intrusion of dust into the insertion portion 21 of the case 2. Moreover, the sticky deposits attached to the mounting board 6 can be removed by the second contact means 5. Therefore, the connector 1 can satisfactorily connect the terminal 61 of the mounting board 6 and the terminal 3 of the connector 1 over time.

  Furthermore, since the connector 1 is configured such that the terminals 3 are connected to the terminals 61 of the mounting board 6 at multiple points, the terminals 61 of the mounting board 6 and the terminals 3 of the connector 1 can be more reliably connected.

  Here, the terminal 3 of the connector 1 is curved in the thickness direction and the width direction of the mounting board 6 inserted from the insertion port 211 of the case 2 as shown in FIG. It is preferable to have contact portions 71 and 72 with the terminal 61. That is, the terminal 3 of the connector 1 is curved in the width direction of the mounting board 6 within the width dimension of the terminal 61 of the mounting board 6. Further, the terminals 3 of the connector 1 are curved in the thickness direction of the mounting board 6 so that the mounting board 6 can be sandwiched at a plurality of locations of the terminals 3 facing each other. That is, the terminals 3 of the connector 1 are arranged such that the contact portions 71 and 72 are shifted with respect to the insertion and extraction directions of the mounting board 6. When the contact portions 71 and 72 are aligned in the insertion and removal directions of the mounting board 6, when the mounting board 6 is inserted or pulled out, the contact portions 71 and 72 pass on the same line of the terminal 61 and the number of times of mutual contact is increased. In many cases, the surface of the terminal 61 is scraped, resulting in poor contact. However, since the terminals 3 of the connector 1 are arranged so that the contact portions 71 and 72 are displaced with respect to the insertion and extraction directions of the mounting board 6 as described above, it is possible to reduce the surface of the terminal 61 from being scraped. it can. Therefore, the occurrence of contact failure over time between the terminal 61 of the mounting board 6 and the terminal 3 of the connector 1 can be reduced over a long period of time.

  Moreover, it is preferable that the first contact means 4 provided with the second contact means 5 is fitted in a fitting portion 22 formed in the case 2. Thereby, even if the 1st contact means 4 and the 2nd contact means 5 are dirty or damaged, it can be replaced | exchanged easily.

  In particular, in a usual case, in order to guide the insertion of the mounting board, a notch portion that is inclined so that the upper end portion of the insertion portion of the case becomes lower toward the insertion portion is formed. Therefore, when the cutout portion is used as the fitting portion 22, it is not necessary to separately form the fitting portion 22 in order to fit the first contact means 4, and the first contact means 4 can be easily inserted into the insertion slot. 211 can be provided. Moreover, it has excellent versatility. At this time, the first contact means 4 has a substantially triangular cross section so that the first contact means 4 can be satisfactorily fitted into the notch.

  The present invention is not limited to the above-described embodiment, and can be changed as appropriate without departing from the spirit of the present invention.
