Summary of the Invention
Problems to be Solved by the Invention
[0006] To achieve a stable electrical connection between connected components, it is crucial to ensure sufficient contact reliability (the degree of stability and certainty of contact between the tab component and the contact). Furthermore, when connecting a tab component to a contact, it is conceivable that the relative position of the tab component to the contact may deviate to some extent from the ideal state. In such cases, it is preferable to ensure the same level of contact reliability between the tab component and the contact.
[0007] In view of the above-mentioned problems, the present invention aims to provide a contact that can absorb misalignment when connecting objects and ensure sufficient contact reliability with tab components, as well as a contact set having said contact. [Means for solving the problem]
[0008] The contact according to the present invention is configured by combining a fixed member fixed to a first connection target and a movable member arranged to slide left and right relative to the fixed member, and a tab component fixed to a second connection target is brought closer from above and below to make contact, thereby electrically connecting the first connection target and the second connection target, wherein a contact portion that contacts the tab component is provided on the movable member (first configuration).
[0009] Furthermore, in the first configuration described above, a connecting unit may be provided which includes left and right contact portions arranged to face each other, a left spring portion that biases the left contact portion to the right, and a right spring portion that biases the right contact portion to the left, and in a state where the tab component is inserted between the left and right contact portions, each of the left and right spring portions biases the corresponding contact portion toward the tab component (second configuration).
[0010] Furthermore, the present invention also relates to a contact set having the contact of the second configuration described above and the tab component, wherein the contact is configured such that in the initial state the movable member is positioned at a predetermined initial position, and in the process of the tab component being brought closer to the contact, the movable member is pushed by the tab component, causing a first sliding operation in which it slides to the left from the initial position (third configuration).
[0011] Furthermore, in the third configuration described above, the tab component may be provided with an inclined portion whose surface faces downward to the left, and the first sliding motion may be performed when the movable member is pressed against the inclined portion (fourth configuration).
[0012] Furthermore, the tab component has a substantially flat plate portion with the left-right direction as the thickness direction, and the contact set of the fourth configuration described above has the flat plate portion inserted between the left and right contact portions, wherein after the first sliding operation is performed, the movable member is pushed by the tip of the flat plate portion to perform a second sliding operation which slides further to the left, and after the second sliding operation is performed, the flat plate portion is inserted between the left and right contact portions (fifth configuration).
[0013] Furthermore, in the fifth configuration described above, the spring portion on the left side may have an inclined surface portion whose surface faces upward to the right, and the contact portion on the left side may be provided in connection with the lower side of the inclined surface portion, and the second sliding operation may be performed when the inclined surface portion is pressed against the tip of the flat plate portion (sixth configuration).
[0014] Furthermore, a contact set having the contact of the first configuration described above and the tab component may be configured such that, in the initial state, the movable member is positioned at a predetermined initial position, and as the tab component is brought closer to the contact, the movable member is pushed by the tab component, causing a first sliding operation in which it slides to the left from the initial position (seventh configuration).
[0015] Furthermore, in the seventh configuration described above, the tab component may be provided with an inclined portion whose surface faces downward to the left, and the first sliding motion may be performed when the movable member is pressed against the inclined portion (eighth configuration).
[0016] Furthermore, a contact set having the contact of the second configuration described above and the tab component may be configured such that the movable member comprises a mounting unit attached to the fixed member so as to be able to slide, and a spring unit connected to the mounting unit and elastically supporting the connecting unit so as to be movable up and down, wherein the spring unit elastically deforms in response to vertical vibration of the tab component when the tab component is inserted between the left and right contact portions (ninth configuration).
[0017] Furthermore, in the first or second configuration described above, the fixing member may have a planar lower surface portion and an upper surface portion that face each other vertically, and the movable member may have a flat plate-shaped insertion portion that is slidably inserted between the lower surface portion and the upper surface portion, and the insertion portion may be provided with a projection portion that presses against the target surface portion which is the lower surface portion or the upper surface portion (10th configuration).
[0018] Furthermore, in the 10th configuration described above, the projection is elastically supported by a leaf spring formed in the insertion portion so as to be movable from side to side, and the leaf spring portion may be configured to elastically deform in response to vibrations in the left-right direction of the movable member when the projection is pressing against the target surface (11th configuration).
[0019] Also, in any one of the configurations from the third to the ninth, the fixing member has flat lower and upper surface portions facing each other vertically, the movable member has a flat plate-shaped insertion portion that is slidably inserted horizontally between the lower surface portion and the upper surface portion, a protruding portion that protrudes toward a target surface portion that is either the lower surface portion or the upper surface portion is provided on the insertion portion, and when the movable member is in the initial position, the protruding portion fits into a hole provided in the target surface portion, and when the movable member slides to the left from the initial position, it may be configured to press against the target surface portion (the twelfth configuration).
[0020] Also, in any one of the configurations from the third to the ninth, the movable member has a stopper portion that prevents the movable member from sliding to the left by being caught by the fixing member when the movable member is in the initial position, and in the process of bringing the tab component closer to the contact, the catch may be released when the movable member is pushed by the tab component (the thirteenth configuration).
Advantages of the Invention
[0021] According to the contact of the present invention, it is possible to absorb misalignment when connecting connection targets and sufficiently ensure contact reliability with the tab component.

[0023] Each embodiment of the contact set of the present invention will be described below with reference to the drawings. The up and down, left and right, and front and back directions (defined for convenience as mutually orthogonal directions) in the following description are as shown in Figure 1, etc. Each embodiment of the contact set has a contact 1 and a tab component 4. The contact 1 has a movable member 2 (also called an upper spring) and a fixed member 3 (also called a base). The movable member 2 and the fixed member 3 are separate components, each formed by bending or other processing of a metal plate. The lower surface of the bottom plate portion 31 of the contact 1, which will be described later, is fixed to the first connection target (e.g., a circuit board) by soldering. The top surface portion 42 of the tab component 4, which will be described later, is fixed to the second connection target (e.g., another circuit board) by soldering.
[0024] 1. First Embodiment First, a first embodiment of the present invention will be described. Figure 1 is a perspective view of the movable member 2 according to the first embodiment. Figures 2A and B are perspective views of the movable member 2 according to the first embodiment, viewed from a different direction than Figure 1.
[0025] The movable member 2 comprises a mounting unit 21, a spring unit 22, and a connecting unit 23. The mounting unit 21 is the part that is attached to the fixing member 3, which will be described later, so that it can slide in the left-right direction. The mounting unit 21 comprises an insertion part 211 and an opposing part 212. The insertion part 211 is a roughly rectangular flat plate with its surface facing in the vertical direction and having front, back, left, and right sides as its outer edge when viewed from below.
[0026] The opposing portion 212 is a part that is bent from the right end of the insertion portion 211 so that its surface faces vertically and faces the insertion portion 211 in the vertical direction. It is a roughly rectangular flat plate shape with sides on the front, back, left, and right as the outer edge when viewed from below. The opposing portion 212 is located above the insertion portion 211.
[0027] Here, Figure 3 is a perspective view of the movable member 2 from below. As shown in Figure 3, the insertion portion 211 has a leaf spring portion 2111. The leaf spring portion 2111 extends from the right and front side of the outer circumference of the insertion portion 211 inward from the outer circumference, and is formed to meander to the left, folding back in the order of rear, front, and rear. On the leftmost portion of the leaf spring portion 2111 that extends in the front-rear direction, a projection 2112 (shown in Figure 2A) protrudes upward from a front position, and a projection 2113 (also shown in Figure 2A) protrudes downward from a rear position. The projections 2112 and 2113 are used to ensure electrical conductivity between the fixed member 3 and the movable member 2 by contacting the fixed member 3, as will be described later.
[0028] Returning to the explanation in Figure 1, the spring unit 22 has a lower plate portion 221, an upper plate portion 222, a lower plate portion 223, and an upper plate portion 224, and elastically supports the connecting unit 23 so that it can move up and down. The lower plate portion 221 is the part that is bent from the left side of the rear edge of the opposing portion 212 and extends forward, and its surface is flat and oriented in the vertical direction. The lower plate portion 221 is above the opposing portion 212 and faces the opposing portion 212 in the vertical direction. The upper plate portion 222 is the part that is bent from the front edge of the lower plate portion 221 and extends rearward, and its surface is flat and oriented in the vertical direction. The upper plate portion 222 is above the lower plate portion 221 and faces the lower plate portion 221 in the vertical direction.
[0029] The lower plate portion 223 is the part that is bent from the right side of the rear edge of the opposing portion 212 and extends forward, and has a flat plate shape with its surface facing in the vertical direction. The lower plate portion 223 is above the opposing portion 212 and faces the opposing portion 212 in the vertical direction. The upper plate portion 224 is the part that is bent from the front edge of the lower plate portion 223 and extends rearward, and has a flat plate shape with its surface facing in the vertical direction. The upper plate portion 224 is above the lower plate portion 223 and faces the lower plate portion 223 in the vertical direction.
[0030] In other words, the lower plate section 221 and the upper plate section 222, and the lower plate section 223 and the upper plate section 224 are paired and arranged on the left and right sides, respectively.
[0031] The connecting unit 23 is the part that connects the tab component 4 to the contact 1, and will be explained using Figure 6. Figure 6 shows a perspective view of the contact 1 and tab component 4 in their initial state, where the movable member 2 is temporarily locked to the fixed member 3. The initial state will be described in detail later.
[0032] As shown in Figure 6, the connecting unit 23 has a left contact portion 231L, a left spring portion 232L, a right contact portion 231R, and a right spring portion 232R. The spring portion 232L is bent upward from the left edge of the upper plate portion 222, extends to the right, and is formed to incline downward to the right. That is, the spring portion 232L has an inclined surface portion 2321L as the portion inclined downward to the right, with its surface inclined so that it faces upward to the right. The contact portion 231L is formed by bending from the lower end of the inclined surface portion 2321L so that it faces the inner surface of the spring portion 232L.
[0033] The spring portion 232R is bent upward from the right edge of the upper plate portion 224, extends to the left, and is formed to incline downward to the left. That is, the spring portion 232R has an inclined surface portion 2321R as the part that inclines downward to the left, with its surface inclined to face upward to the left. The contact portion 231R is formed by bending from the lower end of the inclined surface portion 2321R so as to face the inner surface of the spring portion 232R. The contact portions 231L and 231R face each other in the left-right direction with a gap (a gap smaller than the thickness of the flat plate portion 41 of the tab component 4) in between.
[0034] When the flat plate portion 41 of the tab component 4 is inserted into this gap, the left and right spring portions 232L and 232R are pushed outward in the left-right direction, and elastic force is generated in the left and right spring portions 232L and 232R to bias each contact portion 231L and 231R inward in the left-right direction. As a result, the contact portions 231L and 231R press against the tab component 4 and make contact, connecting the tab component 4 and the contact 1. In this embodiment, the contact set has a large contact area between the tab component 4 and the contact 1, making it suitable for applications where a large current flows between the objects to be connected.
[0035] Furthermore, as shown in Figure 2A, the movable member 2 has a connecting portion 25 and a plate portion 26. The plate portion 26 is a flat plate with thickness in the left-right direction and extending in the front-rear direction, and is connected to the lower plate portion 221 by the connecting portion 25. The upper side of the plate portion 26 is supported by the connecting portion 25. The connecting portion 25 is formed by bending upward from the left edge of the lower plate portion 221, extending to the right, and bending downward. The plate portion 26 has a stopper portion 261 and a projection portion 262. The stopper portion 261 projects downward from the front end of the plate portion 26. The projection portion 262 projects upward from the rear end of the plate portion 26. The functions of the stopper portion 261 and the projection portion 262 will be described later.
[0036] Figure 4 is a perspective view of the fixing member 3 according to the first embodiment. Figure 5 is a perspective view of the fixing member 3 according to the first embodiment, viewed from a different direction than in Figure 4. The fixing member 3 has a bottom plate portion 31, a lower surface portion 32, and an upper surface portion 33. The bottom plate portion 31 is a substantially rectangular flat plate having front, rear, left, and right sides as outer edges when viewed from below. The first connection target can be connected to the lower surface of the bottom plate portion 31 by soldering.
[0037] The lower portion 32 is formed by folding upward from the right edge of the base plate portion 31 and is a substantially rectangular flat plate with front, rear, left, and right sides as outer edges when viewed from below. The lower portion 32 is located above the base plate portion 31 and faces the base plate portion 31 in the vertical direction. The upper portion 33 is a flat plate formed by folding upward from the left edge of the lower portion 32. The upper portion 33 is located above the lower portion 32 and faces the lower portion 32 in the vertical direction. The insertion portion 211 of the movable member 2 can be inserted between the upper portion 33 and the lower portion 32.
[0038] The upper surface portion 33 is provided with a hole 331, an outer wall portion 332, and locking holes 333 and 334, while the lower surface portion 32 is provided with a hole 321, which will be described in detail later. Also, as shown in Figure 4, the fixing member 3 is provided with a bent portion 335 that bends downward at the front end of the upper surface portion 33, and a bent portion 336 that bends downward at the rear end of the upper surface portion 33. These left and right bent portions 335 and 336 cover the space between the lower surface portion 32 and the upper surface portion 33 (the space into which the insertion portion 211 is inserted) from the left and right.
[0039] Furthermore, an example of the size of contact 1 will be explained using Figure 7. The left side of Figure 7 shows a side view of contact 1 and tab part 4 in their initial state, viewed from the left, and the right side of Figure 7 shows a front view of contact 1 and tab part 4 in their initial state, viewed from the front. Figure 7 shows the dimensions (in mm) of contact 1 and tab part 4. As shown in Figure 7, the distance in the front-to-back direction from bent portion 335 to bent portion 336 is 11.6 mm, and the front-to-back dimension of tab part 4 is 5.0 mm.
[0040] Furthermore, as shown in Figure 7, in the fixed member 3, the left-right distance from the bent portion connecting the bottom plate portion 31 and the lower surface portion 32 to the bent portion connecting the lower surface portion 32 and the upper surface portion 33 is 8.6 mm. In the movable member 2, the left-right size of the connecting unit 23 is 9.2 mm. In the contact 1, the vertical distance from the lower end of the fixed member 3 (bottom plate portion 31) to the upper end of the movable member 2 (connecting unit 23) is 8.7 mm. The plate thickness of the movable member 2, fixed member 3, and tab part 4 is 0.5 mm.
[0041] Next, the initial state of contact 1 will be described. As mentioned earlier, Figure 6 is a perspective view of contact 1 in its initial state. The insertion portion 211 of the movable member 2 is inserted from the right between the lower portion 32 and the upper portion 33 of the fixed member 3, and contact 1 in its initial state is obtained.
[0042] Figure 8 shows a cross-sectional view of the contact 1 and tab part 4 in their initial state. This cross-sectional view is a view obtained by cutting with a cross-section that extends in both the left-right and up-down directions. Figure 9 is a magnified view of a part of Figure 8 (magnified view of the dashed area in Figure 8). As shown in Figure 9, in the initial state, the projection 2112 of the movable member 2 is fitted into the hole 331 of the fixed member 3. As shown in Figure 4, the hole 331 is formed as a hole that penetrates the upper surface 33 in the vertical direction. The hole 331 can also be seen as a recess formed by sloping to the left from a position closer to the front on the right edge of the upper surface 33.
[0043] In this initial state, the projection 2112 is fitted into the hole 331, preventing any force from being applied to the projection 2112. In the initial state, the bottom plate portion 31 of the fixing member 3 is connected to the first connection target by reflow soldering (soldering at high temperature). If reflow soldering is performed while force is applied to the projection 2112, stress relaxation will mainly occur in the fixing member 3, and there is a risk that the contact force between the projection 2112 and the fixing member 3 will decrease. Therefore, by performing reflow soldering in a state where no force is applied to the projection 2112 (no-load state) as described above, stress relaxation is suppressed and the decrease in contact force is suppressed.
[0044] Furthermore, in the initial state, the projection 2113 on the movable member 2 (see Figure 3) is fitted into the hole 321 on the fixed member 3 (see Figure 5). As shown in Figure 5, the hole 321 is provided so as to penetrate vertically through the lower surface portion 32. This allows the reflow process described above to be performed when no force is applied to the projection 2113 (no-load state), thereby suppressing the occurrence of stress relaxation and a decrease in contact force.
[0045] Furthermore, as shown in Figure 6, the stopper portion 261 extends downward through a slit 2121 cut out from the rear edge of the opposing portion 212. In the initial state, as shown in Figure 9, the stopper portion 261 contacts the outer wall portion 332 of the fixing member 3. The outer wall portion 332 is provided in connection with the hole 331 at the right edge of the upper surface portion 33, as shown in Figure 4. The surface of the outer wall portion 332 faces to the right. By the stopper portion 261 catching on the outer wall portion 332, the movable member 2 is prevented from moving to the left unintentionally in the initial state (except during the process of bringing the tab component 4 closer to the contact 1 and connecting it). The stopper portion 261 may also be provided so as to contact the outer edge of the lower surface portion 32.
[0046] Furthermore, as shown in Figures 2A and 2B, the movable member 2 is provided with a tip portion 2241 extending in the left-right direction at the rear end of the upper plate portion 224. Also, in the movable member 2, the protruding portion 262 protrudes upward through the gap between the lower plate portions 221 and 223. The protruding portion 262 and the portion near the left end of the tip portion 2241 face each other with a small gap in the vertical direction. The protruding portion 262 and the tip portion 2241 are positioned so that the action of releasing the stopper portion 261 from catching on the outer wall portion 332 (hereinafter referred to as the "stopper release action" for convenience) is properly performed during the process of connecting the tab component 4 to the contact 1.
[0047] Now, let's explain the stopper release operation. In the initial state of contact 1, when the right-side portion of the spring portion 232R is pushed downward by the tab component 4 (inclined portion 44), the tip portion 2241 moves downward along with the spring portion 232R. Note that when the stopper portion 261 is caught on the outer wall portion 332, even if the spring portion 232R is pushed by the tab component 4 in this way, the movable member 2 will not slide to the left.
[0048] Then, when the protruding portion 262 is pushed downward by the downward-moving tip portion 2241, the plate portion 26 moves so that it tilts counterclockwise when viewed from the left side (that is, the protruding portion 262 located towards the rear goes down and the stopper portion 261 located towards the front goes up). This releases the stopper portion 261 from catching on the outer wall portion 332, and the stopper release operation is achieved. After the stopper release operation is performed in this way, when the right-side portion of the spring portion 232R is pushed downward by the tab component 4 (inclined portion 44), the movable member 2 moves to the left (see Figure 11).
[0049] Furthermore, as shown in Figure 2A, the movable member 2 has retaining projections 27 and 28. Retaining projection 27 protrudes upward from the left end and front end of the insertion portion 211, and retaining projection 28 protrudes upward from the left end and rear end of the insertion portion 211. Retaining projections 27 and 28 are fitted into locking holes 333 and 334 of the fixed member 3, respectively. Here, Figure 10 is a front cross-sectional view of the contact 1 in its initial state, seen from the front. Figure 10 shows that retaining projection 28 is fitted into locking hole 334. As a result, in the initial state, retaining projections 27 and 28 contact the right end wall of locking holes 333 and 334, preventing the movable member 2 from coming out to the right from the fixed member 3.
[0050] Next, the tab part 4 will be described using Figure 6. The tab part 4 has a flat plate portion 41, a top surface portion 42, a side portion 43, and an inclined portion 44. The flat plate portion 41 is a flat plate with thickness in the left-right direction and extends in the up-down direction. The top surface portion 42 is a flat plate that extends in the left-right direction, bent to the right from the upper end of the flat plate portion 41. The side portion 43 is a flat plate that extends in the up-down direction, bent downward from the right end of the top surface portion 42. The side portion 43 and the flat plate portion 41 face each other in the left-right direction. The inclined portion 44 is a flat plate that extends so as to be inclined downward to the right from the lower end of the side portion 43. The surface of the inclined portion 44 faces downward to the left. The second connection target can be connected to the top surface portion 42 by soldering.
[0051] The process of moving the tab component 4 downwards and connecting it to the contact 1 will be explained using Figure 11. Figure 11 is a front view showing the process of connecting the tab component 4 to the contact 1 (the process of completing the connection by going through the first and second stages in order). Figure 11(A) shows the connection process when there is no lateral displacement of the tab component 4 relative to the contact 1. Figure 11(B) shows the connection process when the tab component 4 is shifted 1.0 mm to the left. Figure 11(C) shows the connection process when the tab component 4 is shifted 1.0 mm to the right. The dimensions shown in Figure 11 (in mm) indicate the lateral distance between the flat plate portion 41 and the respective contact portions 231L and 231R.
[0052] In Figure 11(A), when the tab component 4 is moved downward, first the position Pa of the inclined portion 44 of the tab component 4 (a position closer to the center in the left-right direction of the inclined portion 44) comes into contact with the spring portion 232R of the connecting unit 23 (see the upper part (first stage) of Figure 11(A)). When the tab component 4 is moved further downward, after the stopper release operation described above is performed, the spring portion 232R is guided by the inclined portion 44, and the movable member 2 moves to the left. Then, as shown in the middle part (second stage) of Figure 11(A), the lower end of the flat plate portion 41 comes into contact with the inclined surface portion 2321L. When the tab component 4 is moved further downward, the lower end of the flat plate portion 41 is guided by the inclined surface portion 2321L, and the movable member 2 moves to the left.
[0053] Then, as shown in the lower part of Figure 11(A) (connection complete), the flat plate portion 41 is inserted between the left and right contact portions 231L and 231R, and the connection between contact 1 and tab portion 4 is completed. In this state (hereinafter sometimes referred to as the "connection complete state"), the left and right spring portions 232L and 232R each bias the corresponding contact portions 231L and 231R toward the flat plate portion 41. When the flat plate portion 41 comes into contact with each contact portion 231L and 231R, the first connection target and the second connection target are electrically connected.
[0054] In Figure 11(B), when the tab component 4 is moved downward, first the position Pb (to the right of position Pa) of the inclined portion 44 of the tab component 4 comes into contact with the spring portion 232R of the connecting unit 23 (see the upper part (first stage) of Figure 11(B)). When the tab component 4 is moved further downward, after the stopper release operation described above is performed, the spring portion 232R is guided by the inclined portion 44, and the movable member 2 moves to the left. As a result, the flat plate portion 41 comes into contact with the inclined surface portion 2321L, similar to Figure 11(A) (see the middle part (second stage) of Figure 11(B)), and finally the flat plate portion 41 is inserted between the left and right contact portions 231L and 231R, and the connection is completed as shown in the lower part (connection complete) of Figure 11(B), and the connection between contact 1 and tab component 4 is completed.
[0055] In Figure 11(C), when the tab component 4 is moved downward, first the position Pc (to the left of position Pa) of the inclined portion 44 of the tab component 4 comes into contact with the spring portion 232R of the connecting unit 23 (see the upper part (first stage) of Figure 11(C)). When the tab component 4 is moved further downward, after the stopper release operation described above is performed, the spring portion 232R is guided by the inclined portion 44, and the movable member 2 moves to the left. As a result, the flat plate portion 41 comes into contact with the inclined surface portion 2321L, similar to Figure 11(A) (see the middle part (second stage) of Figure 11(C)), and finally the flat plate portion 41 is inserted between the left and right contact portions 231L and 231R, and the connection is completed as shown in the lower part (connection complete) of Figure 11(C), and the connection between contact 1 and tab component 4 is completed.
[0056] Since the movable member 2 can slide in the left-right direction, even if the tab component 4 is misaligned in the left-right direction from its ideal state, the misalignment between the tab component 4 and the contact 1 (movable member 2) can be eliminated, improving the reliability of contact with the tab component 4. In particular, in this embodiment, the operation is performed in two stages: a first sliding operation in which the inclined portion 44 is brought into contact with the spring portion 232R to slide the movable member 2, and a second sliding operation in which the flat plate portion 41 is brought into contact with the inclined surface portion 2321L to slide the movable member 2.
[0057] If the connection is completed by only the first sliding motion, parts other than the flat plate portion 41 (especially the side portion 43 and the inclined portion 44) are likely to remain in contact with the contact 1 when the connection is completed. This could lead to unintended contact between the contact 1 and the tab component 4, potentially altering the electrical characteristics between each connected object. Furthermore, if the connection is completed by only the second sliding motion, the lateral dimension of the inclined surface portion 2321L would need to be increased to adequately compensate for any misalignment of the tab component 4, hindering the reduction in the height of the contact 1 (minimizing its vertical dimension).
[0058] In particular, for the flat plate portion 41 to slide smoothly on the inclined surface portion 2321L, the inclination of the inclined surface portion 2321L needs to be approximately 45 degrees or more. Therefore, increasing the lateral dimension of the inclined surface portion 2321L may significantly hinder the reduction in height. To resolve this problem, the above-described two-stage operation is implemented.
[0059] Figure 12 is a side cross-sectional view of contact 1 from the left when the connection is complete. Note that the tab part 4 is not shown in Figure 12. Also, in Figure 12, for the sake of CAD modeling, each projection 2112, 2113 is shown as being transparent to the lower surface 32 or upper surface 33, but in reality, the tips of each projection 2112, 2113 are pressed against the surface of the lower surface 32 or upper surface 33, creating a tight seal.
[0060] The distance between the upper and lower surfaces of the lower surface 32 and the upper surface 33 is slightly greater than the thickness of the leaf spring portion 2111, but slightly smaller than the vertical dimension of the leaf spring portion 2111 in the portion where each projection 2112, 2113 is provided (i.e., the sum of the thickness of the leaf spring portion 2111 and the protruding height of each projection 2112, 2113).
[0061] In the process of connecting the tab component 4 to the contact 1, the movable member 2 slides to the left, causing the projection 2112 to disengage from the hole 331 and be pushed downwards to the upper surface 33. As a result, in the completed connection state as shown in Figure 12, the projection 2112 is pressed against the upper surface 33. Also, in the process of connecting the tab component 4 to the contact 1, the movable member 2 slides to the left, causing the projection 2113 to disengage from the hole 321 and be pushed upwards to the lower surface 32. As a result, in the completed connection state as shown in Figure 12, the projection 2113 is pressed against the lower surface 32.
[0062] As described above, when the protrusions 2112 and 2113 are pressed against the upper surface 33 and lower surface 32, respectively, and vibration occurs in the left-right direction of the movable member 2, the leaf spring portion 2111 (Figure 3) elastically deforms in accordance with this vibration, so that the leaf spring portion 2111 functions to absorb the vibration, thereby suppressing fretting corrosion (micro-sliding wear) between each of the protrusions 2112 and 2113 and the upper surface 33 and lower surface 32.
[0063] Furthermore, various characteristics of the contact 1 in this regard (such as the elastic properties of the leaf spring portion 2111) are appropriately set so as to suppress such fretting corrosion. More specifically, when such vibration occurs, the elastic force generated when the leaf spring portion 2111 is displaced in the left-right direction due to the vibration is set to be smaller than the sum of the frictional forces generated between the protrusions 2112, 2113 and the upper and lower surfaces 33 and 32. As a result, elastic deformation of the leaf spring portion 2111 is more likely to occur than micro-sliding between each protrusion 2112, 2113 and the upper and lower surfaces 33 and 32, and the fretting corrosion is effectively suppressed.
[0064] Furthermore, in the completed connection state where the tab component 4 (flat plate portion 41) is inserted between each contact portion 231L, 231R, if vertical vibration occurs in the tab component 4, the spring unit 22 elastically deforms in accordance with this vibration, thereby absorbing the vibration and suppressing fretting corrosion between each contact portion 231L, 231R and the tab component 4.
[0065] Furthermore, in order to suppress this fretting corrosion, various characteristics of the contact 1 in this regard (such as the elastic characteristics of the spring unit 22) are appropriately set. More specifically, when such vibration occurs, the elastic force generated when the spring unit 22 is displaced vertically due to the vibration is set to be smaller than the sum of the frictional forces generated between each contact part 231L, 231R and the tab part 4. As a result, elastic deformation of the spring unit 22 is more likely to occur than micro-sliding between each contact part 231L, 231R and the tab part 4, and the fretting corrosion is effectively suppressed.
[0066] Figure 13A is a front cross-sectional view of contact 1 as seen from the front when the connection is complete. Note that the tab component 4 is not shown in Figure 13A. During the process of connecting the tab component 4 to contact 1, the stopper release operation described above is performed, causing the movable member 2 to move to the left, and the stopper portion 261 is pressed against the upper surface portion 33. In the completed connection state, electrical connection between the movable member 2 and the fixed member 3 is ensured by contact between the fixed member 3 at three points by the projections 2112, 2113 and the stopper portion 261.
[0067] As described above, contact 1 is composed of a fixed member 3 fixed to the first connection target and a movable member 2 positioned to slide left and right relative to the fixed member 3. The tab component 4 fixed to the second connection target is brought closer from above and below to make contact, electrically connecting the first and second connection targets. Furthermore, contact 1 is configured such that a contact portion that contacts the tab component 4 is provided on the movable member 2. Therefore, contact 1 can absorb left and right positional misalignment when connecting the connection targets (the first connection target to which contact 1 is pre-soldered and fixed, and the second connection target to which the tab component 4 is pre-soldered), and even if there is left and right positional misalignment in the tab component 4, it is possible to ensure sufficient contact reliability with the tab component 4.
[0068] Figure 13B illustrates a state in which connected objects are connected using the contact set of this embodiment. As shown in this figure, the tab component 4, which is fixed to the second connected object with solder H2, fits into the contact 1, which is fixed to the first connected object with solder H1, thereby connecting the first connected object and the second connected object. If stress is generated in each solder H1 and H2, the fatigue limit will deteriorate when repeated stress occurs due to vibration or thermal cycles, and this will cause cracks to occur in each solder H1 and H2. In this respect, with the contact 1 of this embodiment, even if the connected objects are misaligned to the left or right, the movable member 2 slides in that direction, making it possible to secure the connection between the connected objects without generating lateral stress in each solder H1 and H2. As a result, even when repeated stress occurs due to vibration or thermal cycles, cracks are less likely to occur in each solder H1 and H2, and the reliability of the connection is greatly increased.
[0069] Contact 1 also includes a connecting unit 23 which comprises left and right contact portions 231L and 231R arranged to face each other, a left spring portion 232L that biases the left contact portion 231L to the right, and a right spring portion 232R that biases the right contact portion 231R to the left. When the tab component 4 is inserted between the left and right contact portions 231L and 231R, the left and right spring portions 232L and 232R each bias the corresponding contact portions 231L and 231R toward the tab component 4.
[0070] In this manner, contact 1 is designed so that each contact portion 231L, 231R holds the tab component 4 between them. Therefore, even if the tab component 4 is misaligned to some extent in the front-to-back direction, or even if there is some error in the downward movement distance of the tab component 4 (i.e., even if there is some misalignment in the vertical direction), the contact portions 231L, 231R can be kept in a state of holding the tab component 4, thereby ensuring sufficient contact reliability between contact 1 and the tab component.
[0071] Furthermore, even if the tab component 4 experiences a rotational displacement when viewed from the left (a displacement such that it tilts clockwise or counterclockwise from its normal position when viewed from the left), the contact portions 231L and 231R can still be positioned to grip the tab component 4, thereby ensuring sufficient contact reliability between the contact 1 and the tab component.
[0072] Furthermore, even if the tab component 4 experiences a rotational misalignment when viewed from above (a misalignment that causes it to tilt clockwise or counterclockwise from its normal position when viewed from above) or a rotational misalignment when viewed from the front (a misalignment that causes it to tilt clockwise or counterclockwise from its normal position when viewed from the front), the left and right spring sections 232L and 232R each bias the corresponding contact sections 231L and 231R toward the tab component 4, thereby ensuring as much contact reliability as possible between the contact 1 and the tab component.
[0073] In a contact set having a contact 1 and a tab component 4, the contact 1 initially has a movable member 2 positioned at a predetermined initial position. Then, as the tab component 4 is brought closer to the contact 1, the movable member 2 is pushed by the tab component 4, causing it to slide to the left from its initial position in a first sliding motion. The tab component 4 also has an inclined portion 44 whose surface faces downward to the left, and the first sliding motion is performed when the movable member 2 is pushed by the inclined portion 44. By providing the tab component 4 with an inclined portion 44 in this way, the movable member 2 can be pushed to the left while sliding along the inclination of the inclined portion 44, making it possible to perform the first sliding motion smoothly.
[0074] The tab component also has a flat plate portion 41 with the left-right direction as the thickness direction, and the flat plate portion 41 is inserted between the left and right contact portions 231L and 231R. In the contact set, after the first sliding motion is performed, the movable member 2 is pushed by the tip of the flat plate portion 41, causing a second sliding motion to be performed, which slides it further to the left. After the second sliding motion, the flat plate portion 41 is inserted between the left and right contact portions 231L and 231R. This second sliding motion ensures that the movable member 2 is reliably separated from the side portion 43 and inclined portion 44 of the tab component 4, making it possible to bring only the flat plate portion 41 of the tab component 4 into contact with the contact 1.
[0075] Furthermore, the spring portion 232L on the left side has an inclined surface portion 2321L whose surface faces upward to the right, and the contact portion 231L on the left side is provided connected to the lower side of the inclined surface portion 2321L. The second sliding motion is performed when the inclined surface portion 2321L is pressed against the tip of the flat plate portion 41. As a result, the tip of the flat plate portion 41 slides along the inclination of the inclined surface portion 2321L, allowing the second sliding motion to be performed smoothly, and after the second sliding motion, the flat plate portion 41 can be naturally guided to the contact portion 231L on the left side.
[0076] Furthermore, the movable member 2 includes a mounting unit 21 attached to the fixed member 3 so as to be able to slide left and right relative to the fixed member 3, and a spring unit 22 connected to the mounting unit 21 that elastically supports the connecting unit 23 so as to be movable up and down. When the tab component 4 is inserted between the left and right contact portions 231L and 231R, the spring unit 22 is elastically deformed in response to the vertical vibration of the tab component 4. As a result, it is possible to suppress fretting corrosion between each contact portion 231L and 231R and the tab component 4 as much as possible.
[0077] Furthermore, the fixed member 3 has a flat lower surface portion 32 and an upper surface portion 33 that are opposite each other vertically, and the movable member 2 has a flat plate-shaped insertion portion 211 that is slidably inserted between the lower surface portion 32 and the upper surface portion 33. The insertion portion 211 is provided with a projection 2113 that presses against the lower surface portion 32 (a form of the target surface portion) and a projection 2112 that presses against the upper surface portion 33 (a form of the target surface portion). Therefore, it is possible to ensure that each projection 2112, 2113 makes reliable contact with the lower surface portion 32 or the upper surface portion 33, thereby achieving stable electrical contact between the movable member 2 and the fixed member 3.
[0078] Furthermore, each projection 2112, 2113 is elastically supported by a leaf spring portion 2111 formed on the insertion portion 211 so as to be movable from side to side. When each projection 2112, 2113 is pressing against the target surface (lower surface portion 32 and upper surface portion 33), the leaf spring portion 2111 is elastically deformed in response to the vibration of the movable member 2 in the left-right direction. Therefore, it is possible to suppress fretting corrosion between each projection 2112, 2113 and the target surface as much as possible.
[0079] Furthermore, when the movable member 2 is in its initial position, the projection 2112 is fitted into the hole 331 provided in the upper surface 33, and when the movable member 2 slides to the left from its initial position, it presses against the upper surface 33. In addition, when the movable member 2 is in its initial position, the projection 2113 is fitted into the hole 321 provided in the lower surface 32, and when the movable member 2 slides to the left from its initial position, it presses against the lower surface 32. Therefore, when the movable member 2 is in its initial position (i.e., when the contact 1 is in its initial state), stress relaxation due to the reflow process, which is mainly used to connect and fix the contact 1 to the first connection target, is suppressed, and after the reflow process is performed, when the movable member 2 slides to the left from its initial position, it is possible to reliably make contact with the lower surface 32 and upper surface 33, respectively.
[0080] Furthermore, the movable member 2 has a stopper portion 261 that prevents it from sliding to the left by catching on the fixed member 3 (outer wall portion 332) when it is in its initial position. Moreover, as the tab component 4 is brought closer to the contact 1, the movable member 2 is pushed by the tab component 4, releasing the catch (the stopper release operation described above). This makes it possible to suppress the movable member 2 from moving unintentionally to the left in its initial state. In addition, since the stopper release operation is performed naturally as the tab component 4 is brought closer to the contact 1, it is possible to easily implement the stopper release operation in synchronization with the process of connecting the two.
[0081] 2. Second Embodiment Next, a second embodiment of the present invention will be described. The second embodiment is a modified version of the first embodiment described above. Figure 14 is a perspective view showing a part of the movable member 2 according to the second embodiment. Figure 14 shows the configuration of the insertion portion 211 in the movable member 2. In this embodiment, the insertion portion 211 is provided with a front leaf spring portion 2111A and a rear leaf spring portion 2111B.
[0082] The leaf spring portion 2111A extends from the right and front side of the outer circumference of the insertion portion 211 inward, and is formed to meander to the left, folding back in the order of rear, front, and rear. A projection 2112A protrudes upward from the tip of the leaf spring portion 2111A. The leaf spring portion 2111B extends from the right and rear side of the outer circumference of the insertion portion 211 inward, and is formed to meander to the left, folding back in the order of front, rear, and front. A projection 2112B protrudes upward from the tip of the leaf spring portion 2111B.
[0083] Figure 15 is a perspective view of the fixing member 3 according to the second embodiment. As shown in Figure 15, in this embodiment, a front hole 331A and a rear hole 331B are provided in the upper surface portion 33. The holes 331A and 331B penetrate the upper surface portion 33 in the vertical direction.
[0084] When the insertion portion 211 is inserted between the upper portion 33 and the lower portion to reach the initial state, the projections 2112A and 2112B in this embodiment are fitted into the holes 331A and 331B. As a result, no force is applied to the projections 2112A and 2112B, thus suppressing stress relaxation during the reflow process. Furthermore, in the completed connection state where the projections 2112A and 2112B are pressed against the upper portion 33, fretting corrosion can be suppressed by the action of the leaf spring portions 2111A and 2111B, similar to the first embodiment.
[0085] 3. Third Embodiment Next, a third embodiment of the present invention will be described. Figure 16 is a perspective view of the movable member 2 according to the third embodiment of the present invention. In this embodiment, the movable member 2 has insertion portions 211A, 211B, an opposing portion 212, a spring unit 22, and a connecting unit 23.
[0086] In this embodiment, unlike the first embodiment, the insertion portions 211A and 211B are arranged front to back, respectively. The opposing portion 212 is provided in common to the insertion portions 211A and 211B. The opposing portion 212 is divided at the rear into a left portion 212L and a right portion 212R. The spring unit 22 has a left leaf spring portion 220L that extends rearward from the rear end of portion 212L and then bends upward to extend forward, and a right leaf spring portion 220R that extends rearward from the rear end of portion 212R and then bends upward to extend forward.
[0087] The connecting unit 23 has a left connecting portion 230L formed to extend upward by being bent upward from the front end of the leaf spring portion 220L, and a right connecting portion 230R formed to extend upward by being bent upward from the front end of the leaf spring portion 220R. The upper end of the connecting portion 230L has an inclined surface portion 233L whose surface is tilted to face the upper right, and a contact portion 231L connected to the lower end of the inclined surface portion 233L. The upper end of the connecting portion 230R has an inclined surface portion 233R whose surface is tilted to face the upper left, and a contact portion 231R connected to the lower end of the inclined surface portion 233R.
[0088] Figure 17 is a perspective view of the fixing member 3 according to the third embodiment. The fixing member 3 has a bottom plate portion 31, a lower surface portion 32, and an upper surface portion 33. The initial state is achieved when the insertion portions 211A and 211B of the movable member 2 are inserted between the lower surface portion 32 and the upper surface portion 33. In the initial state, the projection 2114A (shown in Figure 16) that protrudes upward on the insertion portion 211A and the projection that protrudes upward on the insertion portion 211B are pressed against the upper surface portion 33. Also in the initial state, the retaining portion 29 that protrudes to the left from the left edge of one side 212L of the opposing portion 212 and then protrudes downward is in opposition to the left side of the upper surface portion 33 in the left-right direction. As a result, the retaining portion 29 can contact the left side of the upper surface portion 33, and the movable member 2 is prevented from coming out to the right.
[0089] Figure 18 is a perspective view showing the state in which the tab component 4 is connected to the contact 1 according to the third embodiment (connection complete state). The tab component 4 has a flat plate portion 41 and a top surface portion 42. The tab component 4 is connected to the contact 1 by inserting the flat plate portion 41 between the contact portions 231L and 231R.
[0090] The process of connecting such a tab component 4 to the contact 1 will be explained using Figure 19. Figure 19 is a front view taken from the front, showing the process of connecting the tab component 4 to the contact 1. Figure 19(A) shows the connection process when there is no lateral displacement of the tab component 4 relative to the contact 1. In Figure 19(A), the lateral center position between each contact portion 231L, 231R in the initial state coincides with the lateral center position of the flat plate portion 41 of the tab component 4. Figure 19(B) shows the connection process when the tab component 4 is shifted 1.0 mm to the right. Figure 19(C) shows the connection process when the tab component 4 is shifted 1.0 mm to the left.
[0091] In the case of Figure 19(A), when the tab part 4 is moved downward, the flat plate part 41 is inserted between the contact parts 231L and 231R, and the contact 1 and the tab part are connected. Initial state
[0092] In the case of Figure 19(B), when the tab part 4 is moved downward, the flat plate portion 41 comes into contact with the inclined surface portion 233R on the right. When the tab part 4 is moved further downward, the flat plate portion 41 is guided by the inclined surface portion 233R, and the movable member 2 slides to the right. Finally, the flat plate portion 41 is inserted between the contact portions 231L and 231R, and the contact 1 and the tab part are connected.
[0093] In the case of Figure 19(C), when the tab part 4 is moved downward, the flat plate portion 41 comes into contact with the left inclined surface portion 233L. When the tab part 4 is moved further downward, the flat plate portion 41 is guided by the inclined surface portion 233L, and the movable member 2 slides to the left. Finally, the flat plate portion 41 is inserted between the contact portions 231L and 231R, and the contact 1 and the tab part are connected.
[0094] Because the movable member 2 can slide in the left-right direction, even if the tab component 4 is misaligned in the left-right direction from its ideal state, the misalignment between the tab component 4 and the contact 1 (movable member 2) can be eliminated, improving the reliability of contact with the tab component 4.
[0095] 4. Summary The configuration of the present invention can be modified in various ways, in addition to the embodiments described above, without departing from the spirit of the invention.
