Description

[Technical Field]

[0001] The present invention relates to a connector for electrically connecting substrates. [Background technology]

[0002] Figures 12 to 14 show the configuration and operation of a card connector described in Patent Document 1 as a conventional example of a connector. This card connector comprises a cover insulator 10, a base insulator 20, contacts 30, and an ejection mechanism 40.

[0003] As shown in Figure 14, the contact 30 is composed of a fixed portion 30a fixed to the underside portion 21 of the base insulator 20, a contact portion 30b that can come into contact with the land 51 of the IC card 50, a spring portion 30c that urges the contact portion 30b upward, and a terminal portion 30d that is connected to a printed circuit board (not shown).

[0004] The cover insulator 10 includes a card support surface 11 that supports the top surface 50a of the IC card 50, side portions 12 that support both side surfaces of the IC card 50, abutment portion 13 against which the leading end 52 of the IC card 50 in the insertion direction abuts, support portions 14 that support both side edges of the bottom surface 50b of the IC card 50, and a guide surface 15 that guides the IC card 50 to the abutment portion 13. The card support surface 11 is located above the contact portions 30b of the contacts 30 and faces the bottom surface portion 21 of the base insulator 20. The side portions 12 are each provided with cylindrical protrusions 16 and 17.

[0005] An opening 23 is formed in the top surface 22 of the base insulator 20, and cam grooves 25, 26 are formed in both side surface portions 24. Cam groove 25 is located on the rear side in the card insertion direction D, and cam groove 26 is located on the front side in the card insertion direction D. The longitudinal direction of cam groove 25 is parallel to the card insertion direction D, and cam groove 25 guides protrusion 16. The longitudinal direction of cam groove 26 is inclined with respect to the card insertion direction D, and cam groove 26 guides protrusion 17 obliquely. This allows cover insulator 10 to move between a first position approaching contact portion 30b of contact 30 and a second position away from contact portion 30b of contact 30.

[0006] In this card connector, before an IC card 50 is inserted, protrusions 16 and 17 of cover insulator 10 are positioned at rear ends 25a and 26a of cam grooves 25 and 26 of base insulator 20, respectively. When IC card 50 is inserted into card insertion slot 27 of base insulator 20 in this state, both side edges of the lower surface 50b of IC card 50 are supported by support portions 14 of cover insulator 10, and IC card 50 is guided to abutment portion 13 in a state parallel to card insertion direction D. Lower surface 50b of IC card 50 is positioned above contact portions 30b of contacts 30, and IC card 50 is not in contact with contact portions 30b of contacts 30 (see FIG. 14A).

[0007] When the IC card 50 is inserted beyond a predetermined insertion distance (the distance until it reaches the abutment portion 13 of the cover insulator 10), the leading end 52 of the IC card 50 abuts against the abutment portion 13 of the cover insulator 10, and then the protrusion 17 of the cover insulator 10 is guided diagonally downward along the cam groove 26, and the leading end of the cover insulator 10 in the card insertion direction approaches the lower surface portion 21 of the base insulator 20. The upper surface 50a of the IC card 50 is pressed downward by the card support surface 11, so that the lands 51 of the IC card 50 come into contact with the contact portions 30b of the contacts 30 (see FIGS. 13 and 14B). As a result, the IC card 50 and the printed circuit board are electrically connected. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 3021370 Summary of the Invention [Problem to be solved by the invention]

[0009] According to the card connector described above, when the IC card 50 is inserted, the tip 52 of the IC card 50 abuts against the abutment portion 13 of the cover insulator 10, and then the cover insulator 10 is pushed by the IC card 50, and the protrusions 16, 17 are guided by the cam grooves 25, 26 of the base insulator 20, causing the IC card 50 to move from the second position to the first position, and the distance that the IC card 50 slides is a short distance that it takes for the cover insulator 10 to move from the second position to the first position.

[0010] In Patent Document 1, by shortening the distance over which the IC card 50 slides against the contact 30 when the IC card 50 is inserted, damage to the IC card 50 and wear on the contact portion 30b of the contact 30 when the IC card 50 is inserted or removed is suppressed.

[0011] However, in the configuration described in Patent Document 1, when the IC card 50 is inserted, there is a sliding state between the IC card 50 and the contact 30, so it can be said that the suppression of wear and damage is still insufficient, and there is room for improvement.

[0012] In view of this, an object of the present invention is to provide a connector that can further reduce wear on the contacts that occurs when a module board is inserted and wear on the electrodes of the module board that come into contact with the contacts than in conventional connectors. [Means for solving the problem]

[0013] According to this invention, a connector which electrically connects a module board having a plurality of electrodes arranged vertically and horizontally on one surface to a main board comprises: a flat housing mounted on the main board; a plurality of contacts which have contact portions protruding from the surface of the housing opposite the surface on which the main board is mounted and connection portions connected to the electrodes of the main board, the contacts being arranged and held in the housing in correspondence with the electrodes of the module board; a flat plate portion located on the surface of the main board opposite the surface on which the housing is mounted; and a pair of side plate portions raised from the flat plate portion so as to sandwich the portion of the main board on which the housing is mounted, the pair of side plate portions having cam grooves and protrusions which form a cam mechanism formed in the pair of side plate portions; and a plate-shaped slider which has the cam grooves and the other protrusions which form the cam mechanism formed in a pair of opposing side portions, the protrusions being inserted into the cam grooves and attached to the frame, thereby forming an insertion space for the module board between itself and the housing mounted on the main board; the slider sliding in the same direction as the insertion direction of the module board into the insertion space, causes the slider to be displaced in a direction which presses the module board inserted into the insertion space by the cam mechanism against the contact portions, and the main board, housing, and module board are sandwiched between the slider and the flat plate portions. [Effects of the Invention]

[0014] According to the present invention, wear of the contacts caused by insertion of the module board and wear of the electrodes of the module board that come into contact with the contacts can be suppressed more than in the prior art, thereby providing a connector with a long life.

[0015] Furthermore, since the main board and module board to be connected and the housing holding the contacts are sandwiched between the frame and slider, bending of the main board and module board can be suppressed, and in this respect, good contact force can be obtained between the electrodes of the module board and the contacts.

DETAILED DESCRIPTION OF THE INVENTION

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described by way of example with reference to the accompanying drawings. [Example]

[0018] Fig. 1 shows the appearance of a connector according to a first embodiment of the present invention, in which a connector 100 is shown attached to a main board 200. Note that only the portion of the main board 200 to which the connector 100 is attached is shown, and other portions are omitted from the illustration.

[0019] Connector 100 is composed of a frame 60, a slider 70, a housing 80, and a large number of contacts 90. Figure 2 shows the configuration shown in Figure 1 exploded into its individual components, and also shows a module board 300 electrically connected to main board 200 by connector 100. First, the configuration of each component will be described.

[0020] The frame 60 is made of a metal plate and has a rectangular flat plate portion 61 and a pair of side plate portions 62 raised from both left and right ends of the flat plate portion 61. A pair of protruding pieces 63 are cut upward and raised in the center of the front end portion of the flat plate portion 61, facing each other, and screw holes 64 are formed on the left and right sides of the front end portion.

[0021] Two cam grooves 65 are formed in each of the pair of side plate portions 62 and arranged in the front-rear direction. The cam grooves 65 are formed as holes penetrating the side plate portions 62, and have a shape in which two elongated holes 65a, 65b extending parallel to the plate surface of the flat plate portion 61 and positioned offset in the up-down direction are connected to each other by an elongated hole 65c inclined with respect to the plate surface of the flat plate portion 61. The elongated hole 65a forming the front side of the cam groove 65 is positioned closer to the flat plate portion 61 than the elongated hole 65b forming the rear side. Note that recesses 66 are formed on the inner surfaces of the pair of side plate portions 62 facing each other, respectively, extending from the upper ends of the side plate portions 62 to the elongated hole 65b.

[0022] The slider 70 is made of a metal plate and has a rectangular plate portion 71. Two protrusions 72 that protrude outward from each other are formed on a pair of opposing sides located at both left and right ends of the plate portion 71, and further, guide portions 73 are formed on each of the opposing sides.

[0023] 3B, the guide portion 73 is composed of an elongated support piece 73a extending in the front-to-rear direction facing the back surface 71a of the plate portion 71, and two extension pieces 73b that are bent and extended from the plate portion 71 to reach the support piece 73a. A guide piece 73c is formed at the rear end of the support piece 73a and extends in a direction away from the back surface 71a of the plate portion 71. A step portion 74 is formed on the back surface 71a side of the plate portion 71 so as to protrude in the shape of a square island, and a notch 75 is formed in the center of the front end.

[0024] The housing 80 is made of resin and has a flat shape. A large number of contacts 90 are arranged vertically and horizontally and held in the housing 80. Note that in Figures 1 and 2 and Figure 4, which is an enlargement of Figure 2, only the contacts 90 located at both ends of the housing 80 in the left and right direction are shown, and the contacts 90 located in the middle are not shown. These contacts 90 are arranged in correspondence with a large number of electrodes (hidden and not visible in Figure 2) arranged vertically and horizontally on one side of the module substrate 300.

[0025] An extension 81 that protrudes forward is formed in the center of the front end of the housing 80, and a protrusion 82 that protrudes upward is formed on the extension 81. A notch 301 into which the protrusion 82 fits is formed in the front end of the module substrate 300.

[0026] A large number of electrodes 201 to which contacts 90 are connected are arranged on a main board 200 to which connector 100 is attached. Note that only the electrodes 201 located at both ends in the left and right direction of the main board 200 are shown, and electrodes 201 located in the middle are not shown. Two notches 202 are formed in the front end of the main board 200, and holes 203 are formed on the outsides of the respective notches 202.

[0027] Next, assembly of the connector 100 and attachment to the main board 200 will be described.

[0028] First, the housing 80 holding the contacts 90 is surface-mounted on the main board 200. The contacts 90 and the electrodes 201 of the main board 200 are connected by soldering.

[0029] Next, the main board 200 is positioned and mounted on the flat plate portion 61 of the frame 60, and two screws 110 are passed through the holes 203 in the main board 200 and the screw holes 64 in the frame 60 to screw the frame 60 to the main board 200. The main board 200 and the frame 60 are positioned by fitting the two protruding pieces 63 of the frame 60 into the two notches 202 in the main board 200.

[0030] Next, the slider 70 is attached to the frame 60. The attachment is performed by inserting the two protrusions 72 formed on each of the pair of opposing sides of the slider 70 into the cam grooves 65 formed on the pair of side plate portions 62 of the frame 60 through the recesses 66.

[0031] This completes the assembly of connector 100 and its attachment to main board 200, resulting in the configuration shown in Fig. 1. As shown in Fig. 1, flat plate portion 61 of frame 60 is located on the side of main board 200 opposite the mounting surface for housing 80, and the pair of side plate portions 62 are positioned so as to sandwich the portion of main board 200 on which housing 80 is mounted.

[0032] FIG. 5 shows the state in which module board 300 is inserted into connector 100 described above and module board 300 and main board 200 are electrically connected. The operation of inserting and connecting module board 300 in connector 100 will be described below.

[0033] 6A shows a cross section before module substrate 300 is inserted (cross section in the state shown in FIG. 1), with slider 70 in a state where protrusion 72 inserted into cam groove 65 of frame 60 is positioned at the rear end side of cam groove 65, i.e., in elongated hole 65b, and protrudes significantly rearward from frame 60. Plate portion 71 of slider 70 is parallel to housing 80 and main board 200, and an insertion space 101 for module substrate 300 is defined between housing 80 and slider 70.

[0034] One end of the contact 90 held in the housing 80 serves as a connection portion 91 that is connected to an electrode 201 of the main board 200, and although the electrode 201 is not shown in FIG. 6A, the connection portion 91 is soldered to the electrode 201. The other end of the contact 90 serves as a contact portion 92 that comes into contact with an electrode of the module board 300 inserted into the insertion space 101, and protrudes from the top surface of the housing 80 (the surface opposite the main board mounting surface). The contact 90 has a spring portion 93 that is bent back into a U-shape, and the free end side of the spring portion 93 serves as the contact portion 92. The contact portion 92 extends in the insertion direction of the module board 300.

[0035] The module substrate 300 is inserted between the plate portion 71 and the guide portion 73 of the slider 70. Both side edges in the width direction (left and right direction) of one surface (bottom surface) of the module substrate 300 on which the electrodes are arranged are supported by the guide portions 73, and the module substrate 300 is guided for insertion into the insertion space 101. Supported and guided by the guide portions 73 in this way, the module substrate 300 is inserted without coming into contact with the contacts 90.

[0036] When the module substrate 300 is inserted into the insertion space 101, its front end abuts against a pair of protruding pieces 63 of the frame 60, restricting further insertion, and the notch 301 formed at the front end in the insertion direction fits into the protrusion 82 provided on the housing 80, thereby positioning the module substrate 300 in the left-right direction (width direction).

[0037] After inserting the module substrate 300, the slider 70 is slid in the same direction as the insertion direction of the module substrate 300. The protrusion 72 of the slider 70 moves along the cam groove 65 of the frame 60 and reaches the front end of the cam groove 65, i.e., the elongated hole 65a. This causes the slider 70 to be displaced in a direction that presses the module substrate 300 inserted in the insertion space 101 against the contact portions 92 of the contacts 90, and the electrodes of the module substrate 300 come into contact with the contacts 90, resulting in an electrical connection. Figure 6B shows this state. Note that the notch 75 formed at the front end of the slider 70 is a relief for the protrusion 82 of the housing 80, and the protrusion 82 of the housing 80 and the slider 70 do not interfere with each other.

[0038] As shown in FIG. 6B, in this connector 100, when the slider 70 is displaced as described above, the main board 200, the housing 80, and the module board 300 are sandwiched between the slider 70 and the flat portion 62 of the frame 60. By adopting such a sandwiching structure, it is possible to prevent, for example, the main board 200 from being bent due to the displacement (pressure) of the slider 70.

[0039] The first embodiment of the connector according to the present invention has been described above. According to the connector 100 described above, the following effects can be obtained.

[0040] (1) Unlike the conventional example, the slider 70 does not have abutting portion against which the inserted module board 300 hits. In other words, the module board 300 does not slide together with the slider 70. Instead, after the module board 300 has been inserted to a predetermined position, the slider 70 can be slid to press the module board 300 against the contact portion 92 of the contact 90. Therefore, unlike the conventional example, the module board 300 and the contact 90 do not slide as the module board 300 is inserted. In this respect, wear on the electrodes of the contact 90 and module board 300 can be suppressed more than in the conventional example, and an increase in contact resistance due to wear can be suppressed, thereby achieving a longer lifespan of the connector than in the conventional example.

[0041] (2) When the module board 300 is inserted and connected, the clamping structure described above can suppress bending of the main board 200, thereby preventing a decrease in the contact force of the contacts 90 due to bending of the main board 200.

[0042] (3) Step portion 74, which is provided on slider 70 so as to protrude in the shape of a square island, limits the contact area between slider 70 and module substrate 300 and concentrates the pressing force on module substrate 300. This prevents warping of module substrate 300 when module substrate 300 is fully connected, and also ensures good contact force between the electrodes of module substrate 300 and contacts 90.

[0043] (4) The module board 300 is removed from the connector 100 by sliding the slider 70 in the opposite direction to that of insertion, moving the module board 300 in a direction away from the contacts 90. At this time, it is possible that the module board 300 moves together with the slider 70. However, in this example, the contact portions 92 of the contacts 90 extend in the insertion direction of the module board 300. Therefore, even if the module board 300 moves together with the slider 70, the contact portions 92 move in the same direction as the movement of the module board 300, and therefore the amount of sliding between the contacts 90 and the module board 300 can be reduced. [Example]

[0044] Fig. 7 shows the appearance of a connector according to a second embodiment of the present invention in the same way as Fig. 1, and Fig. 8 shows the configuration shown in Fig. 7 exploded into its components in the same way as Fig. 2. Components corresponding to those in the first embodiment are given the same reference numerals, and detailed explanations thereof will be omitted.

[0045] In this example, the connector 100' includes a plate 120 in addition to the configuration of the connector 100 of the first embodiment, and therefore the shapes of some of the other parts are also different.

[0046] Plate 120 is a substantially rectangular plate, and protrusions 121 are formed at each of the four corners. Note that slider 70′ does not have step 74, which was formed on slider 70 in Example 1, and plate 120 has step 122 corresponding to step 74.

[0047] Similar to the guide piece 73c, support parts 76 are formed on the rear ends of the pair of opposing sides of the slider 70', protruding rearward, on which the guide part 73 is formed. As shown in Fig. 9B, the support part 76 is formed by extending the plate surface from the extension piece 73b located on the rear side of the two extension pieces 73b.

[0048] In this example, the housing 80' differs from the housing 80 of the first embodiment in that it does not have protrusions 82 for positioning the module board 300, and the module board 300 is positioned in the left-right direction by two protruding pieces 63 provided at the front end of the flat plate portion 61 of the frame 60'. Two notches 302 into which the two protruding pieces 63 fit are formed at the front end of the module board 300 in the insertion direction.

[0049] In this example, the two protruding pieces 63 of the frame 60' function as stoppers against which the inserted module board 300 abuts, and further function to position the main board 200 as well as the module board 300. By using the metal protruding pieces 63 of the frame 60' to position the module board 300 in this way, rather than the resin protrusions 82 formed on the housing 80, the strength of the positioning portion can be improved.

[0050] In this example, a step portion 67 is formed on the flat plate portion 61 of the frame 60' so as to protrude in the shape of a square island toward the mounting surface side of the main board 200, and a pair of side plate portions 62 each have a notch 68 formed at the front end.

[0051] The slider 70' and plate 120 in the connector 100' are attached to the frame 60' by stacking the slider 70' on the plate 120, assembling the slider 70' and plate 120 with the support portions 76 of the slider 70' slipping under the two protrusions 121 located at the rear of the plate 120, and then attaching the slider 70' to the frame 60' in this state.

[0052] By attaching the slider 70' and the plate 120 as described above, the connector 100' is completed, resulting in the configuration shown in Fig. 7. The plate 120 is positioned between the pair of side plate portions 62, with the two protruding portions 121 located at the front positioned above the notches 68 at the front ends of the pair of side plate portions 62, and the two protruding portions 121 located at the rear positioned above the support portions 76 of the slider 70'.

[0053] The plate 120 is positioned in the left-right direction by being sandwiched between a pair of side plate portions 62, and is positioned in the front-rear direction on the frame 60′ by the two front-rear protrusions 121 sandwiching the side plate portions 62 as shown in Fig. 7. Note that the positioning in the left-right and front-rear directions is performed with some play.

[0054] FIG. 10 shows the state in which module board 300 is inserted into connector 100′ and module board 300 and main board 200 are electrically connected. Below, the operation of inserting and connecting module board 300 in this connector 100′ will be explained.

[0055] FIG. 11A shows a cross section before module substrate 300 is inserted (a cross section in the state shown in FIG. 7). Although plate 120 is in an inclined state (diagonal) as shown in FIG. 11A, sufficient insertion space 101 is secured at the rear end portion of slider 70′, so module substrate 300 can be inserted without any problems.

[0056] As in the first embodiment, after module substrate 300 is inserted, slider 70' is slid to electrically connect electrodes of module substrate 300 to contacts 90, but in this example, slider 70' is configured to press module substrate 300 against contact portions 92 of contacts 90 via plate 120. Figure 11B shows this state (connection completed state).

[0057] In the connector 100' of this second embodiment, because the plate 120 is interposed between the slider 70' and the module board 300, it is unlikely that the module board 300 will move along with the sliding of the slider 70'. Therefore, it is not necessary to align the extension direction of the contact portion 92 of the contact 90 with the insertion direction of the module board 300, as in the first embodiment.

[0058] In this second embodiment, plate 120 is provided with step 122 that limits the area of ​​contact with module board 300, and frame 60' is also provided with step 67 that limits the area of ​​contact with main board 200. As a result, main board 200, housing 80', and module board 300 are sandwiched between these step portions 122 and 67, which ensures good contact force between the electrodes of module board 300 and contacts 90, and effectively suppresses bending of main board 200 and module board 300.

[0059] Although the embodiments of the present invention have been described above, the cam grooves and protrusions that constitute the cam mechanism are not limited to those in the first and second embodiments, and the cam grooves may be provided on the slider and the protrusions on the frame.
