Description

  The present invention relates to a connector, and more particularly to a connector that does not short-circuit even if whiskers occur at a connection portion between a wiring member and the connector.

  Usually, a board and a substrate such as a semiconductor device (IC) or between a board and an input / output device (keyboard, liquid crystal panel, etc.) are electrically connected using a connector and a wiring material (cable). ing.

  The connector includes a ZIF (Zero Insertion Force) connector (Patent Document 1, Patent Document 2, Patent Document 3, and Patent Document 4), a non-ZIF type connector (Patent Document 5), and the like. There are FPC (Flexible Printed Circuit) and FFC (Flexible Flat Cable).

  In general, since a copper-based material is used for a contact pin or a wiring material connection terminal which is a conductive portion of a connector, a copper surface treatment is performed in order to prevent contact failure due to oxidation. Examples of the surface treatment include plating with a tin-lead alloy, pure tin, or a tin-based alloy.

  Pure tin and tin-based alloys have a tin oxide film formed on the surface thereof that is more easily mechanically broken than copper oxide, and the oxide film can be easily broken by scratching the surface. When these metals are plated on the contact pins and connection terminals, a fresh surface appears at the contact due to the insertion / extraction of the wiring material, and the contact resistance between the connector and the wiring material is lowered. Furthermore, these metals are inexpensive and widely used as plating materials for contact pins and the like. However, it is known that in a contact pin or connection terminal plated with pure tin or a tin-based alloy, an elongated bowl-shaped single crystal called a whisker is formed from a contact portion where stress is applied.

  The occurrence of this whisker affects the reliability of the connector. In particular, FPC and FFC connectors have a narrow contact pin pitch, and there are no obstacles between adjacent contact pins. Therefore, when a whisker occurs, a short circuit easily occurs between adjacent contact pins. For this reason, when pure tin or a tin-based alloy is plated on contact pins or connection terminals, a decrease in the reliability of the connector becomes a problem.

  On the other hand, it is known that tin-lead alloys do not generate whiskers, but are no longer used due to recent environmental friendliness of electronic devices. Therefore, the following techniques have been disclosed as countermeasures against whiskers that do not use lead.

  Techniques for preventing whisker generation itself by surface treatment are disclosed in Patent Documents 6 and 7.

  Further, Patent Document 8 discloses a connector that suppresses occurrence of a short circuit due to whiskers by increasing the pitch between connection terminals.

Further, Patent Document 9 discloses a connector that prevents whisker growth by providing an obstacle between adjacent power supply terminals to prevent a short circuit. Since the thickness of the whisker is as thin as about 1 μm, it is necessary to bring the obstacle and the wiring material into close contact with each other in order to reliably prevent a short circuit due to the whisker. In the connector of Patent Document 9, an insulating protrusion is arranged as an obstacle between two power supply terminals, and pressure is applied to the protrusion to bring the tip of the protrusion into close contact with the wiring material, thereby preventing a short circuit due to whisker. .
Japanese Utility Model Publication No. 6-29063 JP 2000-133392 A JP-A-11-329629 JP 2002-198112 A JP-A-9-237663 JP 2005-302575 A JP 2006-183068 A JP 2006-179408 A JP 2006-164798 A

  However, in a general FPC or FFC connector, since there is no obstacle between the contacts, the occurrence of a short circuit due to the whisker cannot be reliably prevented. Although it is conceivable to increase the pitch between the connection terminals as in Patent Document 8, in that case, there is a problem that the mounting area of the connector increases.

  The connector disclosed in Patent Document 9 has a complicated mechanism for closely attaching the protrusions to the wiring material, and the distance between the contact pins is, for example, 0.5 mm to 1.0 mm, and can be applied to a connector for a fine FPC or FFC. Have difficulty.

  An object of the present invention is to provide a highly reliable connector that does not short-circuit even if whisker is generated at the connection portion between the wiring member and the connector, and further, even if the interval between contact pins is narrow.

In order to solve the above-described problems of the prior art, the present invention provides a housing having an opening for accommodating a connection portion of a flat wiring member, and a plurality of contacts disposed in the housing and in contact with connection terminals of the connection portion. and the contact pins, possess a septum pin in contact with the portion between the connection terminal of the flat wiring member is arranged between each contact pin, the partition pin, a partition wall in contact with the flat wire member, one end side There is provided a connector characterized in that the connector is fixed to the housing, and the other end side includes an elastically deformable support portion connected to the partition wall .

  According to the wiring material connector of the present invention, the partition pin is disposed between the contact points of the contact pin that is highly likely to generate whiskers, and therefore the possibility of occurrence of a short circuit can be extremely reduced. Thereby, it is applicable also to a connector with a narrower pitch. Moreover, since the partition pin is pressed against the wiring member by elastic force, the wiring member and the partition pin are in close contact with each other. Accordingly, it is possible to prevent the occurrence of a short circuit due to the whisker grown along the surface of the wiring material. Furthermore, the partition pin of the present invention is in close contact with the wiring member by the elastic force of the partition pin itself. For this reason, even when there is some variation in the thickness of the flat wiring material, adhesion can be ensured. Further, the means for bringing the partition pin into close contact with the wiring member may be the same means as a conventional connector having only a contact pin, and can be applied to various types of connectors.

  The partition pin of the present invention may be configured by a partition that contacts the flat wiring member, and an elastically deformable support portion that has one end fixed to the housing and the other end connected to the partition.

  With such a configuration, the partition pin can be elastically deformed, and the occurrence of a short circuit due to the whisker can be prevented by bringing the partition pin into close contact with the wiring member.

  Moreover, it is desirable that the elastic force of the partition pin of the present invention is weaker than the elastic force of the contact pin. Thereby, the partition pin does not hinder the contact of the contact pin, and a stable contact can be ensured.

  Furthermore, the present invention provides a housing having an opening for accommodating a connecting portion of a flat wiring material, a plurality of contact pins disposed in the housing and contacting the connecting terminals of the connecting portion by elastic force, and each contact pin A partition pin disposed between the contact terminals of the flat wiring member between the connection terminals by an elastic force, and a pressing member that presses the flat wiring member toward the contact pin and the partition pin. A connector is provided.

  According to this embodiment, a so-called ZIF type connector can be provided that does not short-circuit even if whiskers occur at the connection portion between the wiring member and the connector.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

(First embodiment)

FIG. 2 is a perspective view of the housing before assembly of the connector according to the first embodiment as viewed from the contact pin insertion port side. FIG. 3 is an enlarged view of the opening of the housing 10 as viewed from the contact side. FIG. 4 is a top view of the connector according to the first embodiment of the present invention. 5A is a cross-sectional view taken along the line AA in FIG. 4 when the wiring material is not connected, and FIG. 5B is a cross-sectional view taken along the line BB in FIG. 4 when the wiring material is not connected. FIG. 6A is a cross-sectional view taken along the line AA of FIG. 4 when the wiring member is connected. 6B is a cross-sectional view taken along the line BB in FIG. 4 when the wiring member is connected.

  As shown in FIG. 1, the connector of this embodiment includes a slider 12, a housing 10, and contact pins 30.

  As shown in FIG. 1, the slider 12 is provided with a bottom plate 13, an insertion port 14, and a fixing member 15. The insertion port 14 penetrates from the front surface to the back surface of the slider 12. Further, the insertion port 14 is formed to be slightly larger than the FFC 20 and can pass the FFC 20 without resistance. The bottom plate 13 is a plate extending from the bottom of the slider 12 and is formed with a width substantially the same as the width of the FFC 20. The bottom plate 13 is used to bring the FFC 20 into contact with the contact pins when the FFC 20 is connected. The fixing member 15 extends on both sides of the slider 12, and a claw that engages with the protrusion of the housing 10 is provided at the tip of the fixing member 15.

  As shown in FIGS. 1 and 2, an opening 16 that houses the tip of the FFC 20 is provided inside the housing 10. The opening 16 is formed with a width slightly wider than the width of the FFC 20. A plurality of contact pin insertion holes 11a are provided at a rear portion of the housing 10 at a predetermined pitch (for example, 0.5 mm to 1.0 mm). The guide grooves 11b and 11c are formed so as to extend from the contact pin insertion port 11a to the front surface as shown in FIGS. The guide groove 11b is an upper groove of the opening 16, and the guide groove 11c is a lower groove.

  As shown in FIG. 5A, the contact pin 30 includes a substrate connection terminal portion 33, a contact side arm 32 that curves and extends from the substrate connection terminal portion 33, and a contact portion provided at an end of the contact side arm 32. 31, a base side arm 34 that faces the contact side arm 32 and extends linearly, and a lance 35 that is provided on the base side arm 34 at an interval. The base side arm 34 is inserted along the guide groove 11c on the bottom side. The lance 35 is fitted into the housing 10 to fix the contact pin 30. On the other hand, the contact side arm 32 is inserted into the guide groove 11b on the upper surface side as shown in FIG. The contact-side arm 32 is disposed with a space between it and the inner wall of the housing 10 so that it can bend in the vertical direction of FIG. Moreover, the contact part 31 is arrange | positioned so that it may protrude below the guide groove 11a. As shown in FIGS. 1 and 4, the board connection terminal portion 33 is a member protruding from the rear of the housing 10 in an assembled state. The connector of the present embodiment is connected by soldering the board connection terminal portion 33 to a terminal of a printed board (not shown).

  The contact pin 30 is made of metal and is manufactured by a known press process. As a material of the contact pin, a material excellent in springiness and conductivity is desirable, and for example, phosphor bronze, brass, beryllium copper, or the like can be used. In this embodiment, it is assumed that the surface of the contact pin is plated with pure tin or a tin-based alloy.

  As shown in FIG. 3, a plurality of partition pins 40 are provided between adjacent contact pins 30 on the upper surface of the opening 16. The partition pin 40 is provided below the wall portion of the upper guide groove 11b, and is fixed to the housing 10 at one end on the back side. Since the partition pin 40 is disposed so as to separate the space from the upper surface of the opening 16, it can be elastically deformed in the vertical direction of FIG. 3.

  The partition pin 40 is formed so that the partition 40 c is located between the contact portions 31 of the adjacent contact pins 30. A flat portion on the entrance side of the partition pin 40 is a partition 40c, and has a flat shape extending in the vertical direction in FIG. 3 as compared with the other portions. The partition wall 40 c extends in the front-rear direction, and is formed so that its length is at least longer than the contact part 31 of the contact pin 30. The end face of the partition pin 40 is formed with a surface and a curved surface inclined from the insertion direction of the FFC 20 so as not to be caught when the FFC 20 is inserted.

  The contact surface 40 a is a flat surface formed below the flat portion of the partition pin 40. The contact surface 40 a is formed to be longer than the contact portion 31 of the contact pin 30. Further, the width of the contact surface 40a is formed to be narrower than the width of the insulating portion between the connection terminals of the FFC 20 so as to contact only the insulating portion of the FFC 20. The elastic support member 40b is a member between the partition wall 40c and the back end. In FIG. 3, the elastic support member 40b is formed to be thinner than the partition wall 40c, but a shape corresponding to the required elastic force can be selected as appropriate. The partition pin 40 is disposed so that the contact surface 40 a portion is located below the contact portion 31. Thereby, the partition pin 40 can contact the FFC 20 reliably. The elastic force of the partition pin 40 is desirably weaker than the elastic force of the contact pin 30 so that the contact pin 30 can be reliably connected to the connection terminal 21.

  The housing 10, the guide grooves 11a and 11b, and the partition pin 40 are manufactured by known injection molding. Similarly, the slider 12 is produced by injection molding. The material of the housing 10 and the slider 12 is an electrically insulating plastic material, and can be appropriately selected from known materials in consideration of dimensional stability, workability, cost, and the like. For example, polyphenylene sulfide (PPS), polybutylene terephthalate (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), or a synthetic material thereof can be used.

  Hereinafter, an operation when the connector of the present embodiment having the above-described configuration and the FFC 20 are connected will be described.

  As shown in FIGS. 5A and 5B, the FFC 20 is inserted into the opening 16 of the housing 10 while the slider 12 is pulled out. The FFC 20 is inserted into the opening 16 of the housing 10 through the insertion port 14. At this time, since the distance between the lower surface of the opening 16 and the contact portion 31 is wider than the thickness of the FFC 20, no force is applied during insertion. The position of the FFC 20 in the horizontal plane is positioned by the insertion port 14 of the slider 12 and the opening 16 of the connector housing 10.

  Next, as shown in FIGS. 6A and 6B, the bottom plate 13 of the slider 12 is inserted below the FFC 20. As a result, the FFC 20 is pushed upward as shown in FIG. 6A, and the contact portion 31 of the contact pin 30 contacts the connection terminal 21 of the FFC 20. At this time, the contact pin 30 is pushed upward by the FFC 20 and elastically deformed. In this way, the contact pin 30 and the FFC 20 are electrically connected. On the other hand, as shown in FIG. 6B, the partition 40 c comes into contact with the insulating portion between the connection terminals 21 of the FFC 20. The partition pin 40 is also pushed up by the FFC 20 when the bottom plate 13 is inserted, and is elastically deformed in the upper surface direction of the housing 10. In this way, the partition 40c and the insulating portion of the FFC 20 are in close contact with each other.

  In this embodiment, the example in which FFC is used as the wiring material has been described. However, the connector of this embodiment can also be used for FPC connection.

  According to the connector of the present embodiment, since the partition pin 40 is disposed in the housing 10 in a state in which it can be elastically deformed in the vertical direction, when connecting the connection terminal 21 of the FFC 20 and the contact pin 30, the partition wall 40a. Adheres closely to the FFC 20. Further, even if there is some variation in the thickness of the flat wiring material, it can be absorbed by the elasticity of the partition pin 40, and the adhesion between the partition wall and the wiring material can be ensured. Thereby, even if a whisker occurs in the contact portion 31, the possibility of occurrence of a short circuit can be extremely reduced. And since the partition 40c and the contact surface part 40a are formed longer than the contact part 31 of the contact pin 30, it is possible to prevent the occurrence of a short circuit due to the whisker grown obliquely or the whisker grown near the surface of the FFC 20, The reliability of the connector can be improved. Further, since the partition pin 40 is elastically deformed in the same manner as the contact pin 30, the means for bringing the partition pin 40 into close contact with the wiring member may be the same as that of the connector having only the contact pin 30, and no special pressing member is required. Furthermore, since the partition pin 40 is in contact with the wiring material in addition to the contact pin 30, the wiring material is difficult to come off. Further, the connector of the present embodiment has a relatively simple structure and can be applied to a connector having a narrow interval between contact pins.

The guide pins 54 are projecting members provided on both sides of the actuator 51 and are fitted into the actuator guide grooves 55 of the housing 50. The bottom plate 56 is a wedge-shaped member extending to one end of the actuator 51 as shown in FIGS. The actuator 51 can be rotated about 90 degrees from a state where it is standing vertically as shown in FIG. 8 to a state where it is lying down horizontally as shown in FIG. The bottom plate 56 is inserted between the two arms of the partition pin 64 (or the contact pin 57) as shown in FIG. 10 when the actuator 51 is lying horizontally.

  As shown in FIG. 9A, the contact pin 57 includes two arms facing each other, and a contact portion 58 is provided at the end of the contact side arm 59. The configuration of the contact pin 57 is the same as that of the contact pin 30 of the first embodiment, and the same material and manufacturing method can be applied.

  As shown in FIG. 9B, the partition pin 64 has two arms extending from the base portion, and a partition wall 65 is provided at one end of the partition side arm 67. As shown in FIG. 8, a part of the partition pin 64 protrudes rearward from the housing 50, but the shape of the partition pin of the present embodiment is not limited to this, and the shape of the partition pin 64 is changed to the housing 50. It is good also as what does not protrude behind. The shape of the partition wall 65 is a flat shape spreading in the vertical direction as compared with the partition wall side arm 67 as shown in FIG. The partition wall 65 extends in the front-rear direction, and is formed so that its length is at least longer than the contact portion 58 of the contact pin 57. The position of the partition wall 56 is provided so as to be disposed at a position that blocks between the contact portions 58 of the adjacent contact pins 57 when assembled. The material of the partition pin 64 of this embodiment should just be insulating. For example, a plastic used for a housing or the like may be injection molded, or a metal material coated with an insulating material may be used.

  As shown in FIG. 8, the partition pins 64 are alternately arranged so that the partition pins 64 are arranged between the adjacent contact pins 57, and each pin is inserted along the guide groove 53 from a pin insertion port (not shown) at the rear of the housing 50. Assembled.

  FIG. 10 is a cross-sectional view of the connector according to the second embodiment of the present invention cut by a partition pin when the actuator is fixed.

  In use, first, an end portion of a wiring material such as FFC or FPC is inserted into the opening with the actuator 54 standing as shown in FIG. In this state, since the distance between the upper surface of the opening of the housing 50 and the contact portion 58 is larger than the thickness of the wiring material, the wiring material can be inserted without resistance. Next, when the actuator 51 is tilted in the horizontal direction as shown in FIG. 10, the bottom plate 56 of the actuator 51 is inserted into the upper part of the wiring member. Thereby, the partition wall side arm 67 of the partition wall pin 64 is elastically deformed, and the partition wall 65 comes into close contact with the insulating portion between the connection terminals of the wiring material. Similarly, the contact side arm 59 of the contact pin 57 is elastically deformed, and the contact portion 58 and the connection terminal of the wiring material come into contact with each other.

  According to the connector of this embodiment, the contact pins and the partition pins are alternately arranged, and the partition walls are in close contact with the insulating portions between the connection terminals of the wiring material. Further, like the connector of the first embodiment, since the partition pin is elastic, even if there is some variation in the thickness of the flat wiring material, it can be absorbed by the elasticity of the partition pin, Adhesion with the wiring material can be ensured. Thereby, even if a whisker occurs, the possibility of occurrence of a short circuit between adjacent connection terminals blocked by a partition wall is extremely low, and the reliability of the connector can be improved.

It has an extended shape. Moreover, the position of the partition 81 is provided so that it may be arrange | positioned in the position which interrupts | blocks between the contact parts 76 of the adjacent contact pin 75, when it assembles. When a force is applied to the vicinity of the rear end of the partition pin in the upward direction of FIG. 12B, it can be elastically deformed in the direction of arrow C as in the case of the contact pin. The same material and manufacturing method as the partition pin 64 of the second embodiment can be applied to the partition pin 80 of the present embodiment.

(Fourth embodiment)
13 to 15 show a connector according to a fourth embodiment of the present invention. The connector according to the fourth embodiment of the present invention is a non-ZIF type connector in which a movable partition is applied to a non-ZIF type connector that secures a pressure that comes into contact with a wiring member only by spring elasticity of a contact pin.

  FIG. 13 is a perspective view showing an appearance of a connector according to the fourth embodiment of the present invention. FIG. 14 is an enlarged view of the opening of the first connector according to the fourth embodiment of the present invention as seen from the contact pin direction.

  As shown in FIG. 13, the first connector of this embodiment mainly includes a housing 90 and contact pins 92.

  The contact pin 92 is inserted along a guide groove 93 provided in the housing 90. The contact pin 92 is manufactured by bending a metal plate and is folded back at one end on the front side as shown in FIG. 14, so that it can be elastically deformed in the vertical direction of FIG. The contact pins 92 are arranged such that the distance from the upper surface of the opening is narrower than the thickness of the wiring material. With such an arrangement, the contact pin 92 is elastically deformed when the tip of the wiring material is inserted, and contact with the connection terminal of the wiring material is ensured by the elastic force of the contact pin 92 itself. The contact pins of the present embodiment are not limited to the shape shown in FIG. 14, and can be applied to, for example, contact pins having a configuration in which a wiring material is sandwiched by elastic force from the upper and lower surfaces. That is, the present invention can be applied to a device that can generate a pressure that contacts the wiring material with the contact pin itself and can hold the wiring material. Moreover, the same material as the contact pin of 1st Embodiment is applicable also to the contact pin of this embodiment.

  Inside the housing 90, an opening 91 extending from the front surface, a guide groove 93, and a partition pin 94 are provided. The guide groove 92 extends from the contact pin insertion port (not shown) in the rear part of the connector housing 90 to the front side. In FIG. 13, the guide groove 93 is formed only on the lower side of the opening 91, but the position of the guide groove of the connector of the present embodiment is not limited to this, and according to the shape of the contact pin, It is good also as a structure provided in the upper and lower surfaces of the opening part 91. FIG. As shown in FIG. 14, a partition wall pin 94 is provided in the opening 91 of the housing 90 at a position where the adjacent contact of the contact pin 91 is blocked. The partition pin 94 is formed in such a shape that a wall between the guide grooves 93 is formed to be higher at a part of the front side, and a notch is formed in a lower portion of the wall. By the cutting, the partition pin 94 can be elastically deformed in the vertical direction of FIG. 14 when the wiring member is inserted. By this elastic force, the partition pin 94 can be brought into close contact with the insulating portion between the connection terminals of the wiring member. The same material and manufacturing method as the housing of the first embodiment can be applied to the housing of the present embodiment.

  According to the first connector of the present embodiment, since the partition wall is in close contact between adjacent contact pins or between connection terminals, a short circuit may occur between adjacent contact pins or between connection terminals even if whiskers occur. Can be made extremely low. Furthermore, like the connector of the first embodiment, since the partition pin 94 is elastic, even if there is some variation in the thickness of the flat wiring material, it can be absorbed by the elasticity of the partition pin 94, Adhesion between the partition wall and the wiring material can be ensured. Thereby, even if a whisker occurs in the connection portion between the wiring member and the connector, there is no short circuit, and the reliability of the connector is improved. The connector of this embodiment is also relatively simple in structure, and can be applied to a connector having a narrow interval between contact pins.

  FIG. 15 is a view showing a second connector according to the fourth embodiment of the present invention. The second connector of this embodiment is the same as the first connector of the fourth embodiment except for the partition walls. The second connector is different from the first connector in that a partition wall pin 95 is provided in the housing 90 instead of the partition wall formed from the walls between the guide grooves 93. As shown in FIG. 15, the partition pin 95 has the same shape as the partition pin of the first embodiment, and the function thereof is also the same. The same material and manufacturing method as the housing of the first embodiment can be applied to the housing 90 of the second connector.

  Also by the 2nd connector of 2nd Embodiment, a partition is closely_contact | adhered between adjacent contact pins or between connection terminals. Further, like the connector of the first embodiment, since the partition pin is elastic, even if there is some variation in the thickness of the flat wiring material, it can be absorbed by the elasticity of the partition pin, Adhesion with the wiring material can be ensured. Thereby, even if a whisker occurs, the possibility that a short circuit occurs between adjacent contact pins or between connection terminals can be extremely reduced, and the reliability of the connector is improved.
