connector

Abstract

To provide a connector which has a long spring length despite its low profile, and moreover enables stable electrical connection.SOLUTION: A terminal 12 of a connector 10 has an elastic contact part 30. A spring part 31 of the elastic contact part 30 is elongated from a lower end 23a of a coupling plate 23 in such a manner that the spring part is at least partially located below an upper surface of a fitting object (a substrate 90). This makes it possible to ensure a spring length of the elastic contact part 30 while keeping a height of the connector 10 low. Because the spring part 31 is a portion which is elongated from the lower end 23a of the coupling plate 23, and the coupling plate 23 is a portion which couples widthwise a pair of lateral plates 22 extending upward from a fixed part 21, a base end 30a of the elastic contact part 30 is prevented from being displaced. As a result, the elastic contact part 30 is prevented from coming into contact with the substrate 90.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present disclosure relates to connectors. [Background technology]

[0002] The connector described in Patent Document 1 has a contact portion that contacts an object to be connected and a spring portion that supports the contact portion. The spring portion is configured so that at least a portion of the spring portion is located below the top surface of the board. This configuration allows the spring length of the spring portion to be increased while maintaining the height dimension of the connector (height dimension from the top surface of the board). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] U.S. Patent No. 10,355,429 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above connector is configured so that a portion of the spring portion contacts the board within the notch portion of the board (Fig. 9 of Patent Document 1). Therefore, the mounting position of the connector relative to the board and the specific shape of the notch portion affect the contact state of the board with the spring portion, which may cause the spring portion to deform in a way that differs from what was assumed at the time of design. If the spring portion deforms in a way that differs from what was assumed at the time of design, a stable electrical connection will be lost.

[0005] Therefore, an object of the present disclosure is to provide a connector that is low in height, has a long spring length, and is capable of achieving stable electrical connection. [Means for solving the problem]

[0006] Hereinafter, the configuration of the connector of the present disclosure will be described using the directional concepts of the front-back direction, the width direction, and the up-down direction. Since these directional concepts are based on the connector, they do not limit the installation direction (posture) when the connector is used.

[0007] The connector according to the first aspect is a connector provided with terminals, wherein the terminals include a fixing portion fixed to an object to be attached, a pair of side plates extending upward from the fixing portion and facing each other in the width direction, a connecting plate connecting the pair of side plates in the width direction with the plate thickness direction oriented in the front-back direction, and an elastic contact portion extending from the connecting plate. The elastic contact portion includes a spring portion extending from the lower end of the connecting plate so that at least a part thereof is located below the upper surface of the object to be attached, and a contact portion supported by the spring portion and displaceable in the front-back direction to contact an object to be connected.

[0008] In the above aspect, the terminals of the connector include a fixing portion fixed to an object to be attached, a pair of side plates extending upward from the fixing portion and facing each other in the width direction, a connecting plate connecting the pair of side plates in the width direction, and an elastic contact portion extending from the connecting plate. The elastic contact portion includes a spring portion and a contact portion supported by the spring portion and displaceable in the front-back direction to contact an object to be connected. Here, the spring portion extends from the lower end of the connecting plate so that at least a part thereof is located below the upper surface of the object to be attached. Therefore, it is possible to secure the spring length of the elastic contact portion while reducing the height of the connector. Further, when the spring portion extends from the lower end of the connecting plate, the connecting plate is a portion that connects the pair of side plates in the width direction with the plate thickness direction oriented in the front-back direction, so that the deformation of the connecting plate is suppressed and the displacement of the base end of the elastic contact portion is suppressed. As a result, the elastic contact portion is prevented from contacting the object to be attached, so that a stable electrical connection can be realized.

[0009] The connector according to the second aspect is, in the first aspect, in a free state, the lower end of the connecting plate is located below the apex position of the contact portion.

[0010] In the above aspect, in the free state, the lower end of the connecting plate is located below the vertex position of the contact portion. Therefore, when a rearward force is applied to the contact portion, the spring portion is likely to deform so that the contact portion moves upward. When the contact portion moves upward, it becomes difficult for the vicinity of the base end of the elastic contact portion to be displaced rearward. As a result, it is further prevented that the elastic contact portion contacts the object to be attached.

[0011] The connector according to the third aspect is, in the first or second aspect, wherein the terminal includes a suction portion that can be suctioned by a suction nozzle, and a connection portion that connects the suction portion and the connecting plate, the connection portion connects the upper end of the connecting plate and the front end of the suction portion, and the front end of the suction portion is located in front of the upper end of the connecting plate.

[0012] In the above aspect, the terminal includes a suction portion that can be suctioned by a suction nozzle, and a connection portion that connects the suction portion and the connecting plate. The connection portion connects the upper end of the connecting plate and the front end of the suction portion, and the front end of the suction portion is located in front of the upper end of the connecting plate. Therefore, compared with the aspect in which the front-rear direction positions of the front end of the suction portion and the upper end of the connecting plate coincide, the suction portion can be arranged on the front side. As a result, the length by which the suction portion protrudes to the rear side can be shortened, and the connector can be miniaturized in the front-rear direction. In addition, when the suction portion can be brought closer to the center of gravity of the connector by arranging the suction portion on the front side, the terminal is prevented from tilting and falling off from the suction nozzle until the terminal is suctioned by the suction nozzle and arranged on the object to be attached.

[0013] The connector according to the fourth aspect is, in the third aspect, wherein the pair of side plates has a side plate enlarged portion located above the upper end of the connecting plate, the side plate enlarged portion is located outside the width direction of the elastic contact portion in the free state or the deformed state, and the side plate enlarged portion does not overlap the connection portion in a side view.

[0014] In the above aspect, the pair of side plates have side plate enlarged portions located above the upper end of the connecting plate. The side plate enlarged portions are located outside the elastic contact portion in the width direction in the free state or the deformed state. The side plate enlarged portions do not overlap the connecting portion in side view. Therefore, the elastic contact portion in the free state or the deformed state can be protected, and it is possible to inspect from the side of the terminal whether the connecting portion of the terminal is correctly manufactured.

[0015] In the connector according to the fifth aspect, in the third or fourth aspect, the rear end of the adsorption portion is a carrier cutting portion cut from the carrier.

[0016] In the above aspect, the rear end of the adsorption portion is a carrier cutting portion cut from the carrier. Therefore, it can be a connector suitable for continuously manufacturing a plate-like member by pressing.

[0017] In the connector according to the sixth aspect, in any of the first to fifth aspects, the fixing portion is configured such that the plate thickness direction is in the vertical direction and can be soldered to the upper surface of the object to be attached, and a slit opening forward is formed on the front side of the fixing portion.

[0018] In the above aspect, the fixing portion is configured such that the plate thickness direction is in the vertical direction and can be soldered to the upper surface of the object to be attached. And a slit opening forward is formed on the front side of the fixing portion. Therefore, on the front side of the fixing portion, the attachment strength to the object to be attached is improved. As a result, even when a force is applied such that the front side of the fixing portion rises with respect to the fixing portion, the fixing portion is prevented from coming off the object to be attached.

[0019] In the connector according to the seventh aspect, in any of the first to sixth aspects, the fixing portion is configured such that the plate thickness direction is in the vertical direction and can be soldered to the upper surface of the object to be attached, the fixing portion is connected to each of the pair of side plates via a pair of curved portions, and the fixing portion has a rear enlarged portion located behind the rear ends of the pair of curved portions.

[0020] In the above aspect, the fixing portion has a rearward expanding portion located rearward of the rear ends of the pair of curved portions. Therefore, the terminal is suppressed from falling backward.

[0021] The connector according to the eighth aspect, in the sixth aspect, the fixing portion does not include a portion located forward of the front ends of the pair of curved portions.

[0022] In the above aspect, the fixing portion does not include a portion located forward of the front ends of the pair of curved portions. Therefore, the mounting position of the terminal on the object to be mounted can be shifted toward the front side of the connector.

Embodiments for Carrying Out the Invention

[0024] Hereinafter, the connector 10 according to the embodiment will be described.

[0025] (Terminal 12) The connector 10 is composed of only the terminal 12 formed of a conductive material.

[0026] (Substrate 90 as an object to be mounted) A notch portion 91 is formed in the peripheral portion of the substrate 90 as the "object to be mounted" to which the connector 10 is attached. The connector 10 is attached to the substrate 90 such that the spring portion 31 is disposed within the notch portion 91.

[0027] (Fixed portion 21, pair of side plates 22, connecting plate 23) The terminal 12 includes a fixed portion 21, a pair of side plates 22, and a connecting plate 23.

[0028] The fixed portion 21 is a portion fixed to the substrate 90 which is the "object to be attached". The fixed portion 21 has its plate thickness direction oriented in the vertical direction and is surface-mounted on the upper surface of the substrate 90. The fixed portion 21 is composed of a right side portion 21R and a left side portion 21L. Each of the right side portion 21R and the left side portion 21L extends outward in the width direction from a curved portion 24 formed below the side plate 22.

[0029] The pair of side plates 22 are portions that extend upward from the fixed portion 21 and face each other in the width direction. Each of the pair of side plates 22 has its plate thickness direction oriented in the width direction. Each of the pair of side plates 22 is provided so as to rise from each of the right side portion 21R and the left side portion 21L of the fixed portion 21 via the curved portion 24.

[0030] The connecting plate 23 has its plate thickness direction oriented in the front-rear direction and is a portion that connects the pair of side plates 22 in the width direction. What the connecting plate 23 connects are the rear ends of the pair of side plates 22. A pair of curved portions 25 extending along the vertical direction are formed between the connecting plate 23 and the pair of side plates 22. The portion between one curved portion 25 and the other curved portion 25 is the connecting plate 23. Accordingly, the lower end 23a of the connecting plate 23 is in the same vertical position as the lower ends of the pair of curved portions 25, and the upper end 23b of the connecting plate 23 is in the same vertical position as the upper ends of the pair of curved portions 25.

[0031] A rearward enlarging portion 21a that enlarges the fixed portion 21 toward the rear side is formed in the fixed portion 21. The rearward enlarging portion 21a is a portion located behind the rear end of the curved portion 24 formed between the fixed portion 21 and the side plate 22. Thereby, the terminal 12 is suppressed from falling backward. On the other hand, a forward enlarging portion that enlarges the fixed portion 21 toward the front side is not formed in the fixed portion 21. As a result, the front end of the fixed portion 21 is in the same front-rear position as the front end of the curved portion 24.

[0032] A slit 21b is formed on the front side of the fixing portion 21. The slit 21b has a shape in which a part of the front edge of the fixing portion 21 is cut out rearward. As a result, the area where the solder fillet is formed increases, and the fixing strength to the substrate 90 in the front portion of the fixing portion 21 increases. Examples of the shape of the slit 21b include a substantially U shape and a substantially V shape, but preferably it is a substantially V shape as shown in the figure.

[0033] As shown in FIG. 4, the side plate 22 has a side plate general portion 22a and a side plate enlarged portion 22b. The side plate enlarged portion 22b is a portion of the side plate 22 that is located above the upper ends (the upper ends 23b of the connecting plate 23) of the pair of bent portions 25. The side plate general portion 22a is a portion of the side plate 22 other than the side plate enlarged portion 22b. As shown in FIG. 5, the side plate enlarged portion 22b is disposed outside the width direction of the elastic contact portion 30 (specifically, the contact portion 32) during deformation. Thereby, the elastic contact portion 30 is appropriately protected.

[0034] As shown in FIG. 4, the side plate enlarged portion 22b has a shape that does not overlap with a connection portion 42 described later in a side view. On the edge of the side plate 22, a first horizontal portion 221, a first inclined end portion 222, a second horizontal end portion 223, a second inclined end portion 224, a vertical end portion 225, and a third inclined end portion 226 are formed. The first horizontal portion 221 extends horizontally forward from the upper end of the bent portion 25. The first inclined end portion 222 extends in a direction inclined upward toward the front. The second horizontal end portion 223 extends forward. The second horizontal end portion 223 is located above the bent portion 42a on the connecting plate side of the connection portion 42 described later. The second inclined end portion 224 extends in a direction inclined downward toward the front. The vertical end portion 225 extends vertically downward. The vertical end portion 225 is formed across the side plate enlarged portion 22b and the side plate general portion 22a. The vertical end portion 225 constitutes the front end of the side plate 22 and is located in front of the front end of the bent portion 24. The third inclined end portion 226 extends in a direction inclined rearward downward.

[0035] (Elastic contact portion 30) Also, the terminal 12 includes an elastic contact portion 30.

[0036] The elastic contact portion 30 extends from the connecting plate 23 and is the portion that elastically contacts the "object to be connected". The elastic contact portion 30 has a spring portion 31 that extends from the lower end of the connecting plate and a contact portion 32 that is supported by the spring portion 31 and contacts the object to be connected 80.

[0037] The spring portion 31 has a proximal straight portion 31a that extends linearly downward from the lower end 23a of the connecting plate 23, a U-shaped bent portion 31b that is bent in a U shape in a side view, and a reverse bent portion 31c that is bent on the side opposite to the U-shaped bent portion 31b, in this order. The upper end of the proximal straight portion 31a coincides with the proximal end 30a of the elastic contact portion 30. The lower end of the proximal straight portion 31a is located below the upper surface of the substrate 90. The U-shaped bent portion 31b is bent with the same curvature from its proximal end to its distal end. The extending direction of the U-shaped bent portion 31b faces downward at the proximal end and upward at the distal end. That is, in the U-shaped bent portion 31b, the extending direction of the spring portion 31 is changed by approximately 180 degrees. The reverse bent portion 31c is formed between the U-shaped bent portion 31b and the contact portion 32.

[0038] The contact portion 32 is bent in a substantially V shape in the plate thickness direction so that the front direction is convex, and contacts the object to be connected 80 near the bent vertex. A bead 32a that protrudes toward the object to be connected 80 side is formed on the contact portion 32. The plate width (dimension in the width direction) of the contact portion 32 is smaller than the plate width of the proximal straight portion 31a. The plate widths of the U-shaped bent portion 31b and the reverse bent portion 31c gradually decrease from the proximal end on the proximal straight portion 31a side to the distal end on the contact portion 32 side.

[0039] When a plane with the normal direction facing the rear is defined as the contact surface 81 of the object to be connected 80, the position where the terminal 12 in the free state first contacts the contact surface 81 when it is moved forward toward the contact surface 81 is called the vertex position 32T of the contact portion 32. The vertex position 32T of the contact portion 32 is located slightly above the lower end 23a of the connecting plate 23 (the proximal end 30a of the elastic contact portion 30).

[0040] (Suction portion 41, connection portion 42) Further, the terminal 12 includes a suction portion 41 that can be suctioned by a suction nozzle, and a connection portion 42 that connects the suction portion 41 and the connection plate 23.

[0041] The suction portion 41 has its plate thickness direction oriented in the vertical direction. The upper plate surface of the suction portion 41 functions as a suction surface. The connection portion 42 connects the upper end 23b of the connection plate 23 and the front end 41a of the suction portion 41. The front end 41a of the suction portion 41 is located in front of the upper end 23b of the connection plate 23.

[0042] The connection portion 42 has a connection plate side bent portion 42a, a non-bent portion 42b, and a suction portion side bent portion 42c. The connection plate side bent portion 42a is formed on the upper side of the connection plate 23, and the upper side portion of the connection plate 23 is bent forward. The non-bent portion 42b extends linearly in a direction inclined upward toward the front. The suction portion side bent portion 42c is bent to the opposite side of the connection plate side bent portion 42a and is connected to the front end 41a of the suction portion 41. The suction portion side bent portion 42c is located behind the front end of the first inclined end portion 222 of the side plate 22 and in front of the rear end of the first inclined end portion 222.

[0043] The connection plate side bent portion 42a, the non-bent portion 42b, and the suction portion side bent portion 42c that constitute the connection portion 42 have the same width dimension as each other. The width dimension of the suction portion 41 is larger than the width dimension of the connection portion 42. Specifically, it is slightly larger than the distance between the inner surfaces of the pair of side plates 22 in the width direction.

[0044] (Deformation of the elastic contact portion 30 due to contact with the object to be connected 80)

[0045] FIG. 5 shows a state in which the connector 10 attached to the substrate 90 is connected to the object to be connected 80. The object to be connected 80 has a contact surface 81 that contacts the contact portion 32 of the terminal 12. The contact surface 81 has its normal direction oriented backward in the connected state.

[0046] The contact portion 32 of the terminal 12 receives a reaction force from the object 80 to be connected, and the elastic contact portion 30 is deformed. When the contact portion 32 of the terminal 12 in the free state receives a rearward force from the object 80 to be connected, the spring portion 31 of the elastic contact portion 30 is deformed, and the contact portion 32 moves rearward and upward and rotates counterclockwise when viewed from the right side (as viewed from the right as shown in FIGS. 4 and 5). That is, when comparing the state before and after deformation in the free state, the contact portion 32 is displaced so as to rotate counterclockwise when viewed from the right side about a virtual rotation axis extending in the width direction passing near the proximal end 30a of the elastic contact portion 30.

[0047] <Function and effect> Next, the function and effect of the present embodiment will be described.

[0048] In the present embodiment, the terminal 12 of the connector 10 includes a fixing portion 21 fixed to the object to be attached, a pair of side plates 22 facing each other in the width direction, a connecting plate 23 connecting the pair of side plates 22 in the width direction, and an elastic contact portion 30 extending from the connecting plate 23. The elastic contact portion 30 includes a spring portion 31 and a contact portion 32 supported by the spring portion 31 and displaceable in the front-rear direction and contacting the object 80 to be connected. Here, at least a part of the spring portion 31 extends from the lower end 23a of the connecting plate 23 so as to be located below the upper surface of the object to be attached (substrate 90). Therefore, while reducing the height of the connector 10 from the substrate surface, the spring length of the elastic contact portion 30 can be ensured. In addition, since the spring portion 31 extends from the lower end 23a of the connecting plate 23 and the connecting plate 23 connects the pair of side plates 22 in the width direction with the plate thickness direction oriented in the front-rear direction, deformation of the connecting plate 23 is suppressed, and displacement of the proximal end 30a of the elastic contact portion 30 is suppressed. As a result, contact between the elastic contact portion 30 and the substrate 90 is prevented, and stable electrical connection can be realized.

[0049] In addition, in the present embodiment, in the free state, the lower end 23a of the connecting plate 23 is located below the apex position 32T of the contact portion 32. Therefore, when a rearward force is applied to the contact portion 32, the spring portion 31 is easily deformed so that the contact portion 32 moves upward. When the contact portion 32 moves upward, it becomes difficult for the vicinity of the proximal end 30a of the elastic contact portion 30 to be displaced rearward, and as a result, it is further prevented that the elastic contact portion 30 contacts the substrate 90.

[0050] Also, in the present embodiment, the terminal 12 includes a suction portion 41 that can be suctioned by a suction nozzle, and a connection portion 42 that connects the suction portion 41 and the connection plate 23. The connection portion 42 connects the upper end 23b of the connection plate 23 and the front end 41a of the suction portion 41, and the front end 41a of the suction portion 41 is located on the front side of the upper end of the connection plate 23. Therefore, compared with the aspect in which the front-rear positions of the front end 41a of the suction portion 41 and the upper end 23b of the connection plate 23 coincide, the suction portion 41 can be disposed on the front side. As a result, the length by which the suction portion 41 protrudes to the rear side can be shortened, and the connector 10 can be miniaturized in the front-rear direction. In particular, in the present embodiment, since the center of gravity of the portion of the terminal 12 excluding the suction portion 41 and the connection portion 42 is located on the front side of the connection plate 23, by disposing the suction portion 41 on the front side, the suction portion 41 can be brought closer to the center of gravity of the terminal 12. As a result, it is possible to prevent the terminal 12 from tilting and falling off from the suction nozzle before the terminal 12 is suctioned by the suction nozzle and disposed on the mounting object (substrate 90).

[0051] Also, in the present embodiment, the pair of side plates 22 has side plate enlarged portions 22b that are located above the upper end of the connection plate 23. The side plate enlarged portions 22b are located outside the width direction of the elastic contact portion 30 in the free state or the deformed state. The side plate enlarged portions 22b do not overlap the connection portion 42 in a side view. Therefore, the elastic contact portion 30 in the free state or the deformed state can be protected, and it is possible to inspect whether the connection portion 42 of the terminal 12 is correctly manufactured by looking at it from the side of the terminal 12.

[0052] Further, in the present embodiment, the rear end 41b of the suction portion 41 is a carrier cutting portion 41b cut from the carrier 50 (FIG. 6). Therefore, it can be used as a connector suitable for continuously manufacturing a plate-like member by press working. That is, when manufacturing the terminal 12 provided with the spring portion 31 extending in a direction intersecting the feeding direction of the carrier as viewed in the developed view before bending, by making the rear end 41b of the suction portion 41 closest to the carrier 50 the carrier cutting portion 41b, the terminal 12 can be easily cut from the carrier 50.

[0053] Also, in the present embodiment, a slit 21b that opens forward is formed on the front side of the fixing portion 21. Therefore, the mounting strength to the object to be mounted (substrate 90) is improved on the front side of the fixing portion 21. As a result, even when a force is applied such that the front side of the fixing portion 21 rises with respect to the fixing portion 21, the fixing portion 21 is prevented from coming off the object to be mounted (substrate 90). In particular, in the present embodiment, in the connection state with the object to be connected 80 (see FIG. 5), as the elastic restoring force of the elastic contact portion 30, a force that causes the upper side of the connecting plate 23 to fall backward acts on the connecting plate 23. Therefore, when the portions of the fixing portion 21, the pair of side plates 22, and the connecting plate 23 of the terminal 12 are regarded as the base portions 21, 22, 23 of the terminal 12, a force that causes the base portions 21, 22, 23 of the terminal 12 to fall backward acts from the elastic contact portion 30. Thus, the slit 21b as described above is effective.

[0054] Also, in the present embodiment, the fixing portion 21 has a rearward enlarged portion 21a located behind the rear ends of the pair of bent portions 24. Therefore, the terminal 12 is suppressed from falling backward. Also, in the present embodiment, the fixing portion 21 does not include a portion located in front of the front ends of the pair of bent portions 24. Therefore, the mounting position of the terminal 12 on the substrate 90 can be shifted toward the front side of the connector.

[0055] Further, in the present embodiment, the terminal 12 does not have a fixing portion behind the connecting plate 23. Therefore, the area required for mounting the terminal 12 on the upper surface of the object to be mounted (substrate 90) can be reduced in the front-rear direction. Although not shown, the terminal 12 may be configured such that the rear end 41B of the suction portion 41 is located at the same position as the connecting plate 23 or in front of the connecting plate 23 in the front-rear direction. By doing so, not only the area of the upper surface of the object to be mounted required for mounting the terminal 12 but also the space on the object to be mounted required for mounting the terminal 12 can be reduced in the front-rear direction.

[0056] 〔Supplementary Explanation of the Above Embodiment〕 Note that the present disclosure is not limited to the above embodiment.

[0057] In the above embodiment, an example in which the pair of side plates 22 face each other in parallel in the width direction has been described. However, the pair of side plates of the present disclosure is not limited to this, and they may face each other in the width direction with a slight angle. Such a pair of side plates also corresponds to the "pair of side plates facing each other in the width direction" of the present disclosure.

[0058] In the above embodiment, an example in which the connector 10 is composed only of the terminal 12 formed of a conductive material has been described. However, the connector of the present disclosure is not limited to this, and may include other components such as a housing for holding the terminal.

[0059] In the above embodiment, an example in which the object to be connected 80 has a contact surface 81 whose normal direction faces backward in the connected state has been described. However, the object to be connected of the present disclosure is not limited to this.

[0060] In the above embodiment, an example in which the fixing portion 21 is surface-mounted on the upper surface of the substrate 90 has been described. However, the fixing portion of the present disclosure is not limited to this, and for example, through-hole mounting may be used.

[0061] In the above embodiment, an example was described in which the spring portion 31 extends downward from the connecting plate 23, the extending direction is changed upward at the U-shaped bent portion 31b, and it is connected to the contact portion 32. However, the spring portion of the present disclosure is not limited to this, and it may extend downward from the connecting plate, change the extending direction upward at a bent portion, and then change the extending direction downward at a further bent portion and be connected to the connecting portion. That is, in the above embodiment, an example was described in which one bent portion (return bent portion) for changing the extending direction of the spring portion in the vertical direction is formed in the spring portion 31. However, the spring portion of the present disclosure may have two formed return bent portions.
