Description

Technical Field

[0001] The invention relates to a connector structure. Background Art

[0002] As a prior art connector, there is a structure as follows: a connector that connects a thin film wire to a substrate is constructed in a non-flip-chip manner, and when the thin film wire is inserted into the housing of the connector, it is inserted with a small force at first, and only at the end is the thin film wire inserted and fixed to the connector with a large force. As a result, it is possible to prevent the contact pins formed on the thin film wire from being damaged or broken, and at the same time, the thin film wire can be inserted into the correct position of the terminal, so that the fixing state of the thin film wire is stable (for example, refer to patent document 1: Japanese Patent Publication No. 2008-504645). Patent document 1 discloses the following thin film wire connector, wherein a plurality of terminals are inserted and fixed to the housing, and when the thin film wire is inserted into the insertion portion of the housing, the contact pins of the thin film wire are in close contact with the contact portion of the terminal (refer to Figure 1 The contact portion is formed on one side of the terminal of the connector, and a seesaw component that performs a seesaw motion with the center portion as the center is integrally formed on the terminal at a position opposite to the contact portion. The seesaw component performs a seesaw motion through the film wire, thereby stabilizing the fixed state of the film wire.

[0003] However, in the connector of the above-mentioned patent document 1, the seesaw component is formed in such a way that the pressurizing portion and the contact portion of the terminal are opposite to each other. For example, when the pressurizing portion and the terminal are relatively deviated due to some influence such as installation error of the terminal, or when a force is generated to separate the contact pin of the membrane wire and the contact portion of the terminal due to warping, etc., stable conduction may not be achieved. Summary of the invention

[0004] In view of the above problems, an object of the present invention is to provide a connector capable of achieving a more stable connection.

[0005] In order to solve the above-mentioned problems, the connector of the present embodiment comprises a housing and a plurality of terminals arranged along the width direction of the housing, i.e., the width direction, wherein the housing comprises: an insertion portion having a predetermined width capable of being inserted into a counterpart connector, wherein the counterpart connector comprises a plurality of counterpart terminals; a base portion located at a predetermined distance from the insertion portion to the counterpart connector, i.e., the insertion direction, wherein the plurality of terminals respectively comprise: a fixed portion having one end fixed to the base portion, an extension portion having one end connected to the fixed portion and the other end extending in the opposite direction of the insertion direction, i.e., the reverse insertion direction, and a connection portion having one end connected to the extension portion and the other end extending in the reverse insertion direction and capable of conducting with the counterpart terminal. Each connection portion of the plurality of terminals comprises: a connection base portion extending from the other end of the extension portion in a cross direction intersecting the insertion direction and the width direction, a first arm portion extending from one end of the cross direction side of the connection base portion in the reverse insertion direction, and a second arm portion extending from the other end of the cross direction side of the connection base portion in the reverse insertion direction. The first arm portion has: a support portion extending from a predetermined position on the extension side of the first arm portion to the second arm portion side in the intersecting direction; a sub-arm portion consisting of a first sub-arm portion extending from an end portion on the extension side of the support portion in the reverse insertion direction and a second sub-arm portion extending from the end portion in the insertion direction; a first contact portion protruding from the first sub-arm portion to the second arm portion side; and a second contact portion protruding from the second sub-arm portion to the second arm portion side. The second arm portion has a pressing portion protruding toward a predetermined position between the first contact portion and the second contact portion, and each connection portion of the plurality of terminals is configured such that when a counterpart connection body is inserted between the respective first arm portion and the second arm portion via the insertion portion, the pressing portion presses the counterpart connection body, so that at least one of the first contact portion and the second contact portion is in conduction with the counterpart connection body.

[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following description, components having the same functions are denoted by the same reference numerals, and repeated descriptions are omitted.

[0021] Figure 2 1 and 10 are perspective views showing a printed circuit board 1 and a mating connector 4 according to the present embodiment, wherein (a) is a view showing a state before the mating connector 4 is inserted into the connector 3, and (b) is a view showing a state after the mating connector 4 has been completely inserted into the connector 3.

[0022] (Other connector 4)

[0023] like Figure 2 As shown, the mating connection body 4 of the present embodiment is composed of a flexible wiring board 9 and a mating insertion portion 8 . Figure 3 1 is a diagram showing a flexible circuit board 9, (a) is a plan view, (b) is a cross-sectional view taken along line XX, and is a diagram showing an enlarged view of the vicinity of electrode 9a, (c) is a front view of the end portion viewed from the electrode 9a side, and (d) is an enlarged view of region Y. The flexible circuit board 9 of this embodiment is a circuit board having a thin plate shape and having a polyimide substrate, for example. The flexible circuit board 9 has, for example, a structure capable of extending in the longitudinal direction (when expressed using coordinate axes, it is Figure 3 The two ends of the positive and negative directions of the y-axis (as shown in (a)) are aligned in a manner such that the flexibility is such that the bending is 180 degrees from the center or greater. Figure 3 As shown in (b), the flexible circuit board 9 is composed of a first layer 91A and a second layer 91B, and the first layer 91A and the second layer 91B are bonded to each other by a predetermined adhesive to form a whole. However, the flexible circuit board 9 is not limited to this structure. For example, it can also be composed of two layers overlapped instead of being a whole. The first layer 91A has a width direction ( Figure 3 The second layer 91B has a plurality of wirings 9A arranged in the width direction of the flexible circuit board 9 (in the left-right direction in (a)). An elongated electrode 9a for electrical connection to the connector 3 is provided at one end of each wiring 9A. The wiring 9A is covered with an insulating layer 9C for insulation. The second layer 91B has a plurality of wirings 9B ( Figure 3 (b)). An elongated electrode 9b for electrical connection to the connector 3 is provided at one end of each wiring 9B. The wiring 9B is covered with an insulating layer 9D for insulation. The plurality of electrodes 9a and 9b are arranged to be offset (shifted) from mutually opposing positions in the width direction of the flexible circuit board 9. By this arrangement, as shown in FIG. Figure 3 As shown in (d), the plurality of terminals, namely electrodes 9a and 9b, are arranged in a staggered manner over the surface on the first layer 91A side and the surface on the second layer 91B side. Since the electrodes 9a and 9b serve as the terminals of the other connecting body 4, in this embodiment, the electrodes 9a and 9b are also referred to as "other terminals".

[0024] The flexible circuit board 9 is on the opposite side to the electrodes 9a and 9b (if expressed using coordinate axes, it is Figure 3 The end portion (on the positive side of the y-axis shown in (a)) has an electrode that can be connected to other devices or equipment. Figure 2 to Figure 4 In the figure, electrodes that can be connected to other devices or equipment are not shown, and the length of the flexible wiring board 9 is limited to a part and is not shown.

[0025] like Figure 2 As shown in (a), the other connecting body 4 is on the side of the electrodes 9a and 9b of the flexible circuit board 9 (if the coordinate axis is used, it is Figure 2 The end portion (the negative side of the y-axis shown in (a)) is provided with a counterpart insertion portion 8 for facilitating the insertion operation into the connector 3. The counterpart insertion portion 8 mainly includes an insertion guide 8a, a claw portion 8b, a rod 8c, and a secondary locking mechanism 8d. Figure 4 (a) is Figure 2 (a) Plan view, Figure 4 (b) is Figure 4 The insertion guide 8a has a substantially box-like shape, and has a box-like hollow shape inside which the flexible circuit board 9 can be inserted. Specifically, Figure 4 As shown in (a) and (b) of FIG. 1 , the insertion guide 8a has a substantially box-like shape and includes side walls 8a1 and 8a2 rising from both sides of the flexible circuit board 9, an upper cover 8a3 covering the upper surface of the flexible circuit board 9, and a lower cover 8a4 covering the lower surface of the flexible circuit board 9. The insertion guide 8a is on the opposite side of the electrodes 9a and 9b (if expressed using coordinate axes, it is Figure 4 The positive direction side of the y-axis shown in (b) of FIG. 1 ) has an opening 8a5, and the electrodes 9a and 9b have an opening 8a5 on the positive direction side of the y-axis shown in (b) of FIG. 1 . Figure 4 The side walls 8a1 and 8a2 are closer to the electrodes 9a and 9b than the upper cover 8a3 and the lower cover 8a4 (in terms of the coordinate axis, Figure 4 The insertion guide 8a is formed to have a box-shaped hollow shape inside, and when the flexible circuit board 9 is arranged inside the insertion guide 8a, the electrodes 9a and 9b can be exposed. The insertion guide 8a has a width dimension ( 1.5 mm x 1.5 mm) slightly shorter than the opening width of the insertion portion 51 of the housing 5. Figure 4 The height of the side walls 8a1 and 8a2 is slightly shorter than the height of the insertion portion 51 so that the other connector 4 can be inserted into the opening of the insertion portion 51. The front ends of the insertion side of the side walls 8a1 and 8a2 are tapered to facilitate insertion into the connector 3. As a result, the insertion guide 8a has a width direction of the insertion portion 51 (when expressed using coordinate axes, it is Figure 4 The positive and negative directions of the x-axis shown in (a) and the up and down directions (height direction. If the coordinate axis is used, it is Figure 4 Positioning in the positive direction and negative direction of the z-axis (as shown in (b)) becomes easy, and insertion of the other connecting body 4 into the connector 3 becomes easy.

[0026] like Figure 2 As shown, the mating insertion part 8 has two claws 8b on the upper cover 8a3, which are used to fit with the locking holes 5c1 provided on the housing 5 of the connector 3 (primary locking). By fitting the claws 8b into the locking holes 5c1, the positional deviation of the mating of the connector 3 and the mating connecting body 4 is prevented. The mating insertion part 8 has a secondary locking mechanism 8d on the upper cover 8a3, which is used to make the mating of the connector 3 and the mating connecting body 4 more reliable. If the printed circuit board 1 is in a stationary state, as shown in FIG. Figure 4 As shown in (b), the other connector 4 is moved toward the direction of the connector 3 (the same direction as the insertion direction P described later) close to the printed circuit board 1, and the other insertion portion 8 of the other connector 4 is inserted into the insertion portion 51 of the connector 3, so that the connector 3 and the other connector 4 are engaged. The side walls 8a1 and 8a2 are provided with a positioning portion 8e ( Figure 2 The positioning portion 8e restricts the insertion of the flexible circuit board 9 into the connector 3 so that the flexible circuit board 9 cannot be inserted further into the base 52 than expected. Figure 4 (b)) side. This prevents, for example, the terminals 6 and the flexible circuit board 9 in the connector 3 from being damaged. After the engagement between the claw 8b and the locking hole 5c1 is completed, the secondary locking mechanism 8d is pressed in along the insertion direction P, and a portion of the protrusions (not shown) provided at both ends of the secondary locking mechanism 8d enters under the rod 8c. As a result, the rod 8c cannot be pressed downward (to the lower cover 8a4 side), so the primary locking cannot be released, and the secondary locking (secondary locking) is completed. This action allows the user to recognize that the connector 3 and the other connecting body 4 have been reliably engaged not only functionally but also visually and consciously. On the upper cover 8a3, a rod 8c ( Figure 2 ). By moving the secondary locking mechanism 8d in the reverse insertion direction P' described later, the secondary locking is released, and the rod 8c can move downward (toward the lower cover 8a4). By pressing the rod 8c downward, the claw 8b also moves downward in conjunction, and the engagement (primary locking) between the claw 8b and the locking hole 5c1 is released.

[0027] (Printed circuit board 1)

[0028] Figure 5 1 is an expanded stereogram of the printed circuit board 1. Figure 5 As shown, the printed circuit board 1 mainly includes a printed wiring board 2 and a connector 3 that can be inserted into a connecting body 4 of another party.

[0029] (Printed circuit board 2)

[0030] The printed wiring board 2 is made of glass epoxy resin as a base material, and the upper surface 2a is electrically connected to the electrodes 9a and 9b of the other connecting body 4 (hereinafter also referred to as "conduction"), and the printed wiring board 2 is connected in the horizontal direction ( Figure 4 A plurality of electrodes 21A and 21B are arranged in the direction of the width dimension W3 in the printed wiring board 2 (hereinafter also referred to as the "width direction W"). The plurality of electrodes 21A and the electrodes 21B are arranged by shifting (moving) from positions relative to each other along the width direction W. As a result, the plurality of electrodes 21A and the electrodes 21B are arranged in a staggered manner on the upper surface 2a of the printed wiring board 2. The printed wiring board 2 has two holes 22 into which the fixing member 7 can be inserted via the hole 54 of the connector 3.

[0031] (Connector 3)

[0032] like Figure 5 As shown, the connector 3 includes a housing 5 and a plurality of terminals 6 as main components.

[0033] The housing 5 is a molded product using a thermoplastic resin such as ABS as a base material, and in this embodiment, is mounted on the upper surface 2a of the printed wiring board 2. The housing 5 of this embodiment has upright walls, i.e., side walls 5a and 5b, and an upper surface 5c and a lower surface 5d covering a portion of the side walls 5a and 5b. Figure 5 The hollow box is formed in the middle, and has: the front side (if expressed using the coordinate axis, it is Figure 5 The insertion portion 51 is on the positive direction side of the y-axis shown in (a); and becomes the inner side (if expressed using the coordinate axis, it is Figure 5 The insertion portion 51 is provided at one end of the housing 5 and has a rectangular opening having a width dimension W3 ( Figure 4 (a)) The direction in which the base 52 is inserted into the other connecting body 4 from the opening of the insertion portion 51 is expressed using coordinate axes. Figure 4 The negative direction of the y-axis (hereinafter also referred to as "insertion direction P") shown in (b) is away from the position of the length D3, and has a rectangular opening having the same width dimension W3 as the opening of the insertion portion 51. The housing 5 is a hollow box-shaped interior into which a plurality of terminals 6 are inserted, and the terminals 6 are pressed and fixed on the lower surface 5d of the housing 5. The details of the terminals 6 will be described later.

[0034] The housing 5 has two locking holes 5c1 that fit into the claws 8b of the other insertion portion 8 near the center of the upper surface 5c on the insertion portion 51 side. Figure 4 As shown, the housing 5 has a direction from the base 52 toward the insertion portion 51 in the hollow housing 5. If the coordinate axis is used, the housing 5 has a direction from the base 52 toward the insertion portion 51 in the hollow housing 5. Figure 4A plurality of guide portions 53 are provided so as to extend (hereinafter also referred to as “extend”) in the positive direction of the y-axis (hereinafter also referred to as “reverse insertion direction P′”) shown in (b). Figure 6 is a diagram for explaining the positional relationship between the terminal 6 and the guide portion 53, (a) is a diagram for Figure 4 FIG. 5 is an enlarged view of region V in (b), and (b) is a schematic diagram for explaining the configuration in the width direction W, viewed from the insertion portion 51 side. In order to facilitate understanding of the structure, Figure 6 In (a), the terminal 6 and the guide portion 53 are shown one each. Figure 6 (b) shows a cross-over of two terminals 6 (terminals 6A, 6B) and the up and down directions (if expressed using coordinate axes, then Figure 6 The three guide parts 53 are arranged in the positive direction and the negative direction of the z-axis shown in (b). Figure 6 In (b), in order to identify the terminal 6 and the guide portion 53, the guide portion 53 is marked with a hatched line. Figure 6 As shown in FIG. 1 , the guide portion 53 is a thin plate-like flat plate standing in a horizontally long state. The guide portion 53 is provided with a cutout portion 53A into which the other connecting body 4 can be inserted. The plurality of guide portions 53 have the same structure. Figure 6 As shown in (b), the guide portion 53 and the terminal 6 are in the width direction W ( Figure 6 (b) are arranged alternately in the left and right direction).

[0035] (Terminal 6)

[0036] like Figure 5 As shown, the plurality of terminals 6 are composed of a plurality of terminals 6A arranged in the width direction W of the connector 3 and electrically connected to the electrode 21A, and a plurality of terminals 6B arranged in the width direction W of the connector 3 and electrically connected to the electrode 21B. Figure 7 is a three-dimensional diagram of terminal 6. Figure 7 In the figure, only six of the plurality of terminals 6 are shown, and the other terminals 6 are not shown. The connector 3 has the same number of terminals 6 as the total number of electrodes 21A and 21B. The plurality of terminals 6 are alternately arranged in the width direction W of the housing 5, with the terminals 6A as the first terminals and the terminals 6B as the second terminals.

[0037] (Terminal 6A)

[0038] Figure 8 These are diagrams that define formal areas in order to illustrate the structure of the terminal 6A, wherein (a) represents the elements that constitute the terminal 6A as a whole, (b) represents the elements that constitute the contact portion 61, (c) represents the elements that constitute the fixed portion 62, (d) represents the elements that constitute the extension portion 63, (e) represents the elements that constitute the connection portion 64, and (f) represents the elements that constitute the first arm portion 66. Fig. 96A is a diagram for explaining the terminal 6A, (a) is a stereogram, and (b) is a plan view. Figure 8 As shown in (a), the terminal 6A is composed of a contact portion 61, a fixing portion 62, an extension portion 63 and a connection portion 64, and has a thin plate shape that is connected to each other and formed into one piece by, for example, punching. The terminal 6A is made of a conductive material such as copper as a base material.

[0039] like Figure 8 As shown in (b), the contact portion 61 is composed of a joint portion 61a electrically connected to the electrode 21A on the printed wiring board 2, and a joint portion 61a extending from one end of the joint portion 61a in the reverse insertion direction P' ( Figure 8 The leg portion 61b extends upward (in the right direction in (b)) and adjusts the length of the contact portion 61, and the contact end portion 61c has a predetermined height longer than the extended width dimension of the leg portion 61b and extends from the leg portion 61b in the reverse insertion direction p'.

[0040] like Figure 8 As shown in (c), the fixing portion 62 is a thin plate connected to the contact portion 61, fixing the terminal 6 to the housing 5. The fixing portion 62 is composed of a fixing base 62a and a fixing extension portion 62b. The fixing base 62a has a substantially quadrilateral flat plate shape, and the insertion direction P side ( Figure 8 The left side of (c) is connected to the contact end 61c, and the lower end (if expressed using coordinate axes, it is Figure 8 The end portion in the negative direction of the z-axis shown in (c) has a fixed end 62a1 (see Fig. 9 (b) The fixed extension portion 62b is formed as a substantially rectangular flat plate extending from the upper surface 5c side of the fixed base 62a toward the upper surface 5c side with a width shorter than the width of the fixed base 62a.

[0041] like Figure 8 As shown in (d), the extension portion 63 is a thin plate connected to the fixed portion 62, and adjusts the pressure on the connection portion 64 caused by the insertion of the flexible circuit board 9. The extension portion 63 has an extension base 63a and extension ends 63b and 63c provided at both ends thereof. The extension end 63b of the extension portion 63 is connected to one end of the fixed extension setting portion 62b of the fixed portion 62 and extends in the reverse insertion direction P'. The extension base 63a extends from the other end of the extension end 63b to the direction of the lower surface 5d ( Figure 8) in (d). The extension end portion 63c extends a predetermined length in the reverse insertion direction P' from the end portion on the lower surface 5d side of the extension base 63a. In the present embodiment, in the extension portion 63, the area of ​​the portion where the extension direction is changed by the extension base 63a and the extension end portion 63b is referred to as the "bend portion 63X". In addition, the area of ​​the portion where the extension direction is changed by the extension base 63a and the extension end portion 63c is referred to as the "bend portion 63Y". The extension portion 63 is connected to the connection portion 64. When the flexible circuit board 9 of the other connector 4 is inserted into the connection portion 64, the extension portion 63 is displaced as follows. With respect to the force in the insertion direction P, the extension base 63a rotates (towards) with the bend portion 63X as a fulcrum. Fig. 9 The bending portion 63Y and the extending end portion 63c are displaced in the insertion direction P (the direction approaching the fixing portion 62) in conjunction with this movement, and the connecting portion 64 is also displaced accordingly. Fig. 9 In other words, when the force in the cross direction I is directed upward (toward the upper surface 5c), the extension end portion 63c rotates with the curved portion 63Y as a fulcrum. Fig. 9 The extension portion 63c is displaced in the counterclockwise direction in (b), and is displaced in the clockwise direction when the force in the cross direction I is on the lower side (lower surface 5d side). As a result, the extension end portion 63c is displaced in the cross direction I. In addition, the connection portion 64 is also displaced along with the displacement of the extension end portion 63c. That is, the extension portion 63 has a first bend (bend 63X) that can displace at least a portion of the extension portion 63 in a direction close to the fixed portion 62, and a second bend (bend 63Y) that can displace at least a portion of the extension portion 63 in the cross direction I. In addition, the terminal 6 of the present invention can also be configured to have any one of the bends 63X and 63Y.

[0042] Therefore, the extension portion 63 adjusts the pressure of the flexible circuit board 9 on the connection portion 64 through the elastic force generated by the bent portions 63X and 63Y. The bent portions 63X and 63Y can, for example, cope with the deviation caused by the pressing posture of the terminal 6 into the housing 5, the contact position and angle deviation caused by the manufacturing error of the terminal, etc., and can reduce the insertion force of the flexible circuit board 9 when inserting it into the connection portion 64, which helps to prevent damage and improve reliability.

[0043] The connection portion 64 has a thin plate shape with one end connected to the extension end portion 63c of the extension portion 63 and the other end extending in the reverse insertion direction P'. As described below, the connection portion 64 is configured to be electrically connected to the other connection body 4 by inserting the other connection body 4 into the connector 3.

[0044] (Connection 64)

[0045] like Figure 8 As shown in (e), the connection portion 64 is composed of a connection base 65, a first arm portion 66, and a second arm portion 67.

[0046] The connection base portion 65 extends from the extension end portion 63 c of the extension portion 63 in the intersecting direction I and is formed into a substantially rectangular flat plate.

[0047] like Figure 8 As shown in (f), the first arm portion 66 is composed of a main arm portion 66a, a support portion 66b, and a sub-arm portion 66c. The main arm portion 66a extends linearly from the upper surface 5c side of the cross direction I of the connection base 65 to the reverse insertion direction P' to form a slender flat plate. The main arm portion 66a has a shape that tapers as it moves toward the extension direction. The support portion 66b extends from a predetermined position (at the extension side) of the main arm portion 66a. Figure 8 In (f), the end of the main arm portion 66a, but not limited to the end) extends to the second arm portion 67 side (lower surface 5d side) in the cross direction I by a length only shorter than the extension length of the first arm portion 66, and becomes the fulcrum of the seesaw action of the auxiliary arm portion 66c. Figure 8 As shown in (f), the auxiliary arm portion 66c is composed of a first auxiliary arm portion 66A extending from the end of the extension side of the support portion 66b to the anti-insertion direction P' side, and a second auxiliary arm portion 66B extending from the end of the extension side of the support portion 66b to the insertion direction P. The extension length LA of the first auxiliary arm portion 66A ( Fig. 9 ) is shorter than the extension length LB of the second auxiliary arm portion 66B. As a result, the spring constant of the second auxiliary arm portion 66B is lower than that of the first auxiliary arm portion 66A, and when the flexible circuit board 9 is inserted, the displacement of the second auxiliary arm portion 66B is greater than that of the first auxiliary arm portion 66A. As a result, the insertion force of the flexible circuit board 9 into the other connector 4 can be reduced.

[0048] like Fig. 9 As shown, the first auxiliary arm portion 66A has a first contact portion 66Ap protruding toward the second arm portion 67 side (lower surface 5d side) in the cross direction I. The first contact portion 66Ap is configured to be electrically connected to the electrode of the flexible circuit board 9 by inserting the other connecting body 4 into the connector 3. The first auxiliary arm portion 66A has a first protrusion 66Ao protruding from the end portion on the insertion portion 51 side toward the main arm portion 66a side (upper surface 5c side) in the cross direction I. At least a portion of the first protrusion 66Ao is opposite to the adjacent guide portion 53, and overlaps in the width direction W with a predetermined gap ( Figure 6). Thus, the movement of the first protrusion 66Ao in the width direction W is restricted. The front end position of the end portion of the protrusion side of the first protrusion 66Ao is closer to the auxiliary arm portion 66c side (lower surface 5d side) than the position on the upper surface 5c side in the intersecting direction I of the main arm portion 66a by only a length t1 ( Figure 8 (e)). Since the first arm portion 66 has elasticity, it moves in the cross direction I due to the insertion of the flexible circuit board 9. When a force is applied to the first arm portion 66 in an upward direction (in the direction of the upper surface 5c), the first arm portion 66 moves in an upward direction (in the direction of the upper surface 5c). The main arm portion 66a is closer to the upper surface 5c side than the first protrusion 66Ao by a length of only t1, thereby functioning as a gap that enables the seesaw action of the auxiliary arm portion 66c. The end of the extended side of the first auxiliary arm portion 66A has a second gradient portion, namely a gradient portion 66As, which is inclined toward the main arm portion 66a side (upper surface 5c side) in the cross direction I as it moves toward the reverse insertion direction P' with the first contact portion 66Ap as the starting point.

[0049] like Fig. 9 As shown, the second auxiliary arm portion 66B has a second contact portion 66Bp protruding toward the second arm portion 67 side (lower surface 5d side) in the cross direction I. The second contact portion 66Bp is configured to be electrically connected to the electrode of the flexible circuit board 9 by inserting the other connecting body 4 into the connector 3. The second auxiliary arm portion 66B has a second protrusion 66Bo protruding from the end of the extension side (base 52 side) toward the main arm portion 66a (upper surface 5c side). At least a portion of the second protrusion 66Bo is opposite to the adjacent guide portion 53, and overlaps in the width direction W with a predetermined gap ( Figure 6 ). As a result, the movement of the second protrusion 66Bo in the width direction W is restricted. The second protrusion 66Bo and the main arm portion 66a are located at a position separated by a predetermined distance in the intersecting direction I. Fig. 9 As shown in FIG. 1 , a recessed portion 66H is provided on the main arm portion 66a at a position opposite to the second protruding portion 66Bo to avoid contact with the second protruding portion 66Bo. The end portion of the second sub-arm portion 66B on the extended side (on the base 52 side) has a third gradient portion, namely, a gradient portion 66Bs, which is inclined toward the main arm portion 66a side (on the upper surface 5c side) in the intersecting direction I with the second contact portion 66Bp as the starting point as it moves toward the reverse insertion direction P'.

[0050] The second arm portion 67 extends from the lower side (lower surface 5d side) of the connecting base 65 in the cross direction I to the reverse insertion direction P' side to form a slender flat plate. The second arm portion 67 has a tapered shape, extends in the reverse insertion direction P' direction to a position halfway in the extension direction, and then extends on the extension side in a manner such that the front end is inclined toward the upper surface 5c side as it extends in the reverse insertion direction P'. As a result, the spring constant of the second arm portion 67 is increased. In addition, the first arm portion 66 has a seesaw structure consisting of a straight main arm portion 66a, a supporting portion 66b and a sub-arm portion 66c, and the spring constant is suppressed to be lower than that of the second arm portion 67. The extended end portion 63c side ( Fig. 9 The end portion (on the left side in (b)) is connected to the extended end portion 63c. This connection position is a predetermined position between the end portion on the upper side (on the upper surface 5c side) and the end portion on the lower side (on the lower surface 5d side) of the cross direction I of the connection base 65. Fig. 9 In the embodiment, the position is set in the central part, but is not limited thereto.

[0051] like Fig. 9 As shown in (b), the second arm portion 67 has a pressing portion 67p on the extended side. The pressing portion 67p protrudes toward a predetermined position between the first contact portion 66Ap and the second contact portion 66Bp on the auxiliary arm portion 66c. The pressing portion 67p in this embodiment is located at a position opposite to any one portion (G) of the second auxiliary arm portion 66B. It is preferred that the length ( Figure 8 (f)) and the position of the pressing portion 67p, the position of G is determined in a manner that the moment acting on the first contact portion 66Ap and the second contact portion 66Bp is balanced. According to this positional relationship, even if, for example, the flexible circuit board 9 is warped and a force that separates the first contact portion 66Ap and the electrode of the flexible circuit board 9 acts, a pressing force acts between the second contact portion 66Bp and the electrode of the flexible circuit board 9 (contact pressure is ensured), and the electrical contact between the terminal 6 and the flexible circuit board 9 can be well maintained. As the position of G, for example, it is considered to be set to a position closer to the second contact portion 66Bp than the center position between the first contact portion 66Ap and the second contact portion 66Bp. The pressing portion 67p presses the flexible circuit board 9 of the inserted counterpart connector 4. The end of the second arm 67 on the insertion portion 51 side (the extension side of the second arm 67) has a first gradient portion, namely, a gradient portion 67s, which is inclined in a direction away from the auxiliary arm 66c (the lower surface 5d side) as it moves toward the insertion portion 51 side (the anti-insertion direction P' side) with the pressing portion 67p as the starting point. At least a portion of the end of the second arm 67 on the insertion portion 51 side faces the adjacent guide portion 53 and overlaps in the width direction W with a predetermined gap ( Figure 6). Therefore, the movement of the end of the second arm portion 67 on the insertion portion 51 side in the width direction W is restricted. The pressing portion 67p and the first contact portion 66Ap are separated by a length t2 in the intersecting direction I, and the pressing portion 67p and the second contact portion 66Bp are separated by a length t3 in the intersecting direction I ( Figure 8 (e)). In the present embodiment, t2 and t3 are ensured to be slightly shorter than the thickness of the flexible circuit board 9 so that the flexible circuit board 9 can be inserted, and the pressing force of the pressing portion 67p and the contact pressure of the first contact portion 66Ap and the second contact portion 66Bp with the flexible circuit board 9 should be appropriately ensured. However, t2 and t3 are not limited to this, and can also be set to other lengths as long as the contact pressure with the flexible circuit board 9 can be increased. In this case, for example, t2 and t3 can also be configured to be 0 (zero) or negative (in Figure 8 In (e), the position of the pressing portion 67p in the intersecting direction I is closer to the upper surface 5c than the first contact portion 66Ap or the second contact portion 66Bp).

[0052] (Terminal 6B)

[0053] Fig.10 6B are diagrams for explaining terminal 6B, (a) is a perspective view, and (b) is a plan view. Fig.10 As shown, the terminal 6B is composed of a contact portion 61B, a fixing portion 62, an extending portion 63 and a connecting portion 64B.

[0054] The contact portion 61B does not have a Figure 8 The portion corresponding to the leg portion 61B and the contact end portion 61 c in (b) is formed in a shape similar to the bonding portion 61 a and is electrically bonded to the electrode 21B on the printed wiring board 2 .

[0055] The fixing portion 62 and the extending portion 63 of the terminal 6B have the same shapes as the fixing portion 62 and the extending portion 63 of the terminal 6A.

[0056] The connection portion 64B has the same structure as the connection portion 64 of the terminal 6A. However, the connection portion 64B is configured to be connected to the extension portion 63 of the terminal 6B in a state in which the connection portion 64B has the same shape as the connection portion 64 of the terminal 6A and is inverted (rotated 180 degrees) about the insertion direction P. By this inversion, the terminal 6B is configured to have the pressing portion 67p on the upper surface 5c side and the first contact portion 66Ap and the second contact portion 66Bp on the lower surface 5d side.

[0057] The assembly of the connector 3 is completed by inserting the terminal 6 into the housing 5 and pressing it in to fix it. In each terminal 6A of the connector 3 as the first terminal, each first contact portion 66Ap is arranged at a position overlapping with respect to the width direction W, each second contact portion 66Bp is arranged at a position overlapping with respect to the width direction W, and each pressing portion 67p is arranged at a position overlapping with respect to the width direction W. In each terminal 6B of the connector 3 as the second terminal, each first contact portion 66Ap is arranged at a position overlapping with respect to the width direction W, each second contact portion 66Bp is arranged at a position overlapping with respect to the width direction W, and each pressing portion 67p is arranged at a position overlapping with respect to the width direction W.

[0058] (Installation of Connector 3 on Printed Wiring Board 2)

[0059] The process of mounting the connector 3 on the printed wiring board 2 to obtain the printed wiring board 1 is performed, for example, by the following steps (see Figure 5 ). Apply solder paste to electrodes 21A and 21B of printed wiring board 2. Align terminal 6A of connector 3 with electrode 21A of printed wiring board 2, and align terminal 6B of connector 3 with electrode 21B of printed wiring board 2, and align hole 54 of housing 5 with hole 22 of printed wiring board 2. Insert fixture 7 from above (upper surface 5c) to fix printed wiring board 2 and connector 3. In this state, heat treatment is performed using a reflow furnace or the like to complete the electrical connection between terminal 6 and printed wiring board 2, thereby obtaining printed circuit board 1.

[0060] (Insertion of the other connecting body 4 into the connector 3)

[0061] Fig.11 is Figure 6 In (a), a diagram showing the case where the other connector 4 is inserted. To facilitate understanding, Fig.11 In, relative to Figure 6 (a) is a schematic diagram in which only the flexible circuit board 9 is added. When the printed circuit board 1 having the connector 3 is fixed (stationary), the other connector 4 is moved along the insertion direction P to insert the printed circuit board 1 ( Figure 4As described above, the height of the side wall 8a1 of the other insertion portion 8 is configured to be slightly shorter than the height of the insertion portion 51, and the front end of the flexible circuit board 9 is inserted in a manner that is guided to the position between the first contact portion 66Ap and the pressing portion 67p in the cross direction I. Assuming that any part of the front end of the flexible circuit board 9 is inserted slightly above the first contact portion 66Ap and the pressing portion 67p in the cross direction I, since the terminals 6A and 6B have gradient portions (gradient portion 66As, gradient portion 67s, gradient portion 66Bs), the terminals 6A and 6B behave as follows. When the front end of the flexible circuit board 9 contacts the gradient portion 66As, the first arm portion 66 moves to the upper side (upper surface 5c side) when the front end of the flexible circuit board 9 contacts the terminal 6A, and moves to the lower side (lower surface 5d side) when the first arm portion 66 contacts the terminal 6B. At the same time, the auxiliary arm portion 66c is inclined so that the second contact portion 66Bp is separated from the main arm portion 66a (in other words, the auxiliary arm portion 66c is inclined so that the first contact portion 66Ap is close to the main arm portion 66a). When the flexible wiring board 9 is further inserted to the insertion direction P side and the front end of the flexible wiring board 9 contacts the gradient portion 67s, the second arm portion 67 moves downward (toward the lower surface 5d) when the front end of the flexible wiring board 9 contacts the terminal 6A, and moves upward (toward the upper surface 5c) when the front end of the flexible wiring board 9 contacts the terminal 6B. When the flexible wiring board 9 is further inserted to the insertion direction P side and the front end of the flexible wiring board 9 contacts the gradient portion 66Bs, the auxiliary arm portion 66c is inclined so that the second contact portion 66Bp is close to the main arm portion 66a (in other words, the auxiliary arm portion 66c is inclined so that the first contact portion 66Ap is separated from the main arm portion 66a). That is, it is configured to be difficult for the terminal 6 to be bent when the flexible wiring board 9 is inserted into the terminal 6.

[0062] Through the above actions, such as Fig.11 As shown, the front end of the flexible circuit board 9 is stably inserted to the vicinity of the connection base 65. The movement of the other connector 4 to the connector 3 at the predetermined position is completed by the locking mechanism between the locking hole 5c1 of the housing 5 and the claw 8b of the other inserting portion 8 and the positioning portion 8e being restricted in the insertion direction P. The secondary locking mechanism 8d is moved in the insertion direction P, so that the secondary locking function is activated, and the insertion of the other connector 4 is completed.

[0063] According to the connector 3 of the present embodiment, when the other connecting body 4 is inserted between the auxiliary arm portion 66c and the second arm portion 67, the other connecting body 4 is pressed by the pressing portion 67p. As a result, the electrodes 9a and 9b contact the first contact portion 66Ap and the second contact portion 66Bp respectively, generating a reaction force of the pressing force. If attention is paid to one wiring and electrode such as the wiring 9A and the electrode 9a, the flexible circuit board 9 is constituted as a two-end support beam whose one surface is supported by the first contact portion 66Ap and the second contact portion 66Bp and the other surface is pressed by the pressing portion 67p. That is, the pressing portion 67p is not provided at a position opposite to the first contact portion 66Ap or the second contact portion 66Bp, so the pressing force of the pressing portion 67p is not concentrated on one contact portion. Therefore, the insertion force of the flexible circuit board 9 can be reduced. This can reduce damage to the flexible wiring board 9 and improve the reliability of the connection between the first contact portion 66Ap and the electrodes 9a and 9b and the connection between the second contact portion 66Bp and the electrodes 9a and 9b.

[0064] The first arm portion 66 has a so-called seesaw structure composed of a support portion 66b and an auxiliary arm portion 66c, and the spring constant is suppressed to be lower than that of the second arm portion 67. In this way, due to the insertion of the flexible circuit board 9, the displacement toward the first arm portion 66 side (auxiliary arm portion 66c side) becomes larger than the second arm portion 67 side, and the seesaw structure can also reduce the insertion force of the flexible circuit board 9, and damage to the flexible circuit board 9 can be prevented.

[0065] The seesaw structure improves the reliability of the connection. That is, the pressing force applied to the first contact portion 66Ap and the length LAp ( Figure 8 The moment generated by (f)) is equal to the pressing force applied to the second contact portion 66Bp and the length LBp ( Figure 8 In this case, even if insufficient conduction occurs between one of the first contact portion 66Ap and the second contact portion 66Bp, conduction can be achieved through the other contact portion, so it is foreseeable that the reliability of the connection with the other connecting body 4 will be improved.

[0066] The structure of the second arm 67 ensures that the pressing portion 67p has an appropriate pressing force, thereby ensuring the connection reliability of the first contact portion 66Ap and the second contact portion 66Bp. Therefore, in order to ensure the connection with the electrodes 9a and 9b of the flexible circuit board 9, there is no need to provide a separate component for ensuring the pressing force.

[0067] By arranging the terminal 6A as the first terminal and the terminal 6B as the second terminal alternately, the direction of pressing the flexible circuit board 9 alternates between the upper side and the lower side when viewed from the width direction W, so that good contact can be maintained even when a force such as impact acts on the flexible circuit board 9.

[0068] The above is an explanation of the embodiment of the present invention. By adopting the above structure, when the counterpart connection body 4 is inserted between the respective first arm parts 66 and second arm parts 67 via the insertion part 51, the pressing part 67p presses the counterpart connection body 4, so that at least one of the first contact part 66Ap and the second contact part 66Bp is connected to the counterpart connection body 4. Thus, a stable connection can be achieved.

[0069] (Variation Example)

[0070] Fig.12 This is a stereoscopic diagram of a case where a plurality of terminals 6' are unified into the same shape. The connector 3 of this embodiment can replace Figure 7 The plurality of terminals 6 shown in FIG. 6A and 6B are composed of terminals 6A and 6B, and the Fig.12 The use shown consists of only one terminal ( Fig.12 In this case, the other connecting body 4 is prepared Figure 3 Among the wirings 9A, 9B and the electrodes 9a, 9B, for example, the counterpart connection body 4 on which the wiring 9B and the electrode 9b are mounted.

[0071] That is, a counterpart connection body 4 having a flexible circuit board (flexible circuit board 9' not shown) having wiring and electrodes provided on only one surface is prepared. Even in this case, the counterpart connection body 4 uses the first contact portion 66Ap and the second contact portion 66Bp as fulcrums, and by applying pressure from the pressing portion 67p, a reaction force of a pressing force sufficient to conduct with at least one of the first contact portion 66Ap and the second contact portion 66Bp is generated on the counterpart connection body 4 by utilizing the moment balancing effect similar to the above-mentioned two-end support beam, so that conduction with the counterpart connection body 4 is possible. In this case, even if conduction with one of the first contact portion 66Ap and the second contact portion 66Bp is insufficient, conduction can be achieved through the other contact portion, so that it is expected that the reliability of connection with the counterpart connection body 4 will be improved.

[0072] The above describes the embodiments and variations of the present invention. The number of terminals 6 in the present embodiment is described by taking the case where the terminals 6A and 6B are the same number (23 respectively), but this is only an example, and the number of terminals 6 as a whole can also be changed according to the coordination with the wiring of the flexible circuit board 9. In addition, the number of terminals 6A and 6B is not necessarily the same, and can also be appropriately adjusted according to the layout of the flexible circuit board 9. The present embodiment is described by taking the case where the flexible circuit board 9 and the printed circuit board 1 are wired approximately horizontally as an example, but in the case where the flexible circuit board 9 is wired approximately vertically relative to the printed circuit board 1, the housing 5 can also be installed approximately vertically on the printed circuit board 1. In addition, it goes without saying that the printed circuit board and the other connector described in the present embodiment can be appropriately changed without departing from the scope of the purpose of the present invention.
