Description

Technical Field

[0001] This invention relates to a connector mounted on a circuit board, which connects a conductive portion on the surface of the circuit board to a conductor on the target side. Background Technology

[0002] Traditionally, substrate-mounted connectors, such as the one disclosed in Patent Document 1, are well-known as connectors mounted on a substrate. In the substrate-mounted connector of Patent Document 1, surface-mount pins hang down from the four corners of a slightly rectangular mating surface, forming an opening in the mating surface. Furthermore, in the substrate-mounted connector of Patent Document 1, contact pieces extend inward and downward from the outside of the mating surface to form opposing contact portions, and a downwardly inclined guide portion is formed at the inner edge of the opening. Moreover, in the substrate-mounted connector of Patent Document 1, if the inserted tab terminal is slightly misaligned, this guide portion provides guidance; if the tab terminal is significantly misaligned, it prevents deformation of the contact piece by abutting against the mating surface. [Previous Technical Documents] [Patent Literature]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-339906

[0004] However, Patent Document 1 has the following problem: when the vertical terminal is in contact with the contact portion, if the position of the contact portion is significantly offset in the direction of elastic deformation, the load will be applied to the feet hanging down from the four corners of the mating surface through the contact surface. As a result, the solder of the connecting portion at the front end of the foot and the connecting circuit will be stripped, causing the connecting portion and the connecting circuit to become unable to be electrically connected. Summary of the Invention

[0005] The purpose of this invention is to maintain an electrically stable connection even when there is a positional shift of the connecting conductor on the object side during or after connection.

[0006] The connector of the present invention is mounted on a circuit board and is integrally formed by a conductive portion on the surface of the circuit board and a metal plate connecting a target-side connecting conductor. It is characterized by having: a top portion having a window opening through which the target-side connecting conductor can be inserted; a pair of fixing portions fixed and connected to the conductive portion; a pair of floating portions connecting the top portion to the pair of fixing portions respectively; and a connecting portion connecting to the target-side connecting conductor that passes through the window opening. Each pair of floating portions includes: a drooping portion extending downwards from the end of the top portion into two forks; a pair of opposing portions opposing the drooping portions of the two forks respectively; and a folding portion connecting the lower end of the drooping portion to the lower end of the opposing portion. The pair of fixing portions bend outwards from the upper end of the opposing portions. The connecting portion extends downwards from the end of the top portion between the two forks of the drooping portion, and the lower end of the connecting portion is located below the pair of fixing portions.

[0007] When the object-side connecting conductor in the insertion window is connected to the connecting part, and when or after the object-side connecting conductor and the connecting part are connected, the object-side connecting conductor shifts position relative to the connector, the floating part absorbs the load from the object-side connecting conductor.

[0008] According to the present invention, even if there is a positional shift of the object-side connecting conductor when or after connection with the object-side connecting conductor, an electrically stable connection can be maintained. Attached Figure Description

[0010] Hereinafter, with reference to the figures, a connector according to an embodiment of the present invention will be described in detail. In the figures, the x-axis, y-axis, and z-axis are formed as a three-axis orthogonal coordinate system. The positive direction of the y-axis is defined as the forward direction, the negative direction of the y-axis as the backward direction, the x-axis as the left-right direction, the positive direction of the z-axis as the upward direction, and the negative direction of the z-axis as the downward direction.

[0011] (First Implementation) <Connector Structure> The following is for reference only. Figures 1 to 8 The structure of the connector 1 according to the first embodiment of the present invention will be described in detail.

[0012] The connector 1 is formed into one piece by punching and bending a metal plate, and the surface is plated. It has: a top part 2, a fixing part 3, a floating part 4, a connecting part 5, a connecting part 6, and a guiding part 7.

[0013] The top part 2 is equipped with a plug 200 that can be used as a conductor for connection to the object side. Figures 1 to 8 (The details are omitted) A through hole, i.e., a window hole 21, that can be inserted in the vertical direction.

[0014] The fixing part 3 is provided in pairs and is formed by bending outward from the upper end of the opposing part 42 (described later) of the floating part 4. The fixing part 3 fixes and connects to the conductive part of the circuit pattern (not shown) on the circuit board 100 by welding or the like.

[0015] The floating part 4 is a pair located on the left and right sides of the top part 2, respectively connecting the top part 2 to a pair of fixed parts 3 and allowing for elastic deformation. The floating part 4, as shown in... Figure 2 The frontal view shown is V-shaped. Specifically, the floating part 4 has a hanging part 41, an opposing part 42, and a folding part 43.

[0016] The lower portion 41 is bifurcated from the ends 2a and 2b of the aforementioned top portion 2 and extends downward. The length of the lower portion 41 in the width direction (y-axis direction) is shorter than the length of the fixed portion 3 in the width direction.

[0017] The opposing portions 42 are a pair, extending downward from the inner end of the fixing portion 3 into a double fork, and opposing the downward-hanging portion 41 of the double fork. The pair of opposing portions 42 are connected by the fixing portion 3. At least a portion of the opposing portions 42 extends upward in a direction away from the downward-hanging portion 41. The length of the opposing portions 42 in the width direction (y-axis direction) is shorter than the length of the fixing portion 3 in the width direction.

[0018] The folding part 43 connects the lower end of the hanging part 41 to the lower end of the opposing part 42.

[0019] The connecting portion 5 is provided between the two forks of the hanging portion 41, extending downward from the end 2a of the top portion 2. For example... Figure 5 As shown, the connecting portion 5 is wider on the upper side than on the lower side and is tongue-shaped. The cross-sectional shape of the connecting portion 5 is as follows... Figure 6 As shown, it is shaped like a "ㄑ". The lower end 5a of the connecting part 5 is located below the fixing part 3, and as shown... Figure 5 As shown, it is located between the two forks of the connecting part 6.

[0020] The connecting portion 6 is formed between the two forks of the hanging portion 41, extending downward from the end 2b of the top portion 2 and connecting at the lower end 6a. The cross-sectional shape of the connecting portion 6 is as follows: Figure 6 As shown, it is shaped like an inverted "U". The lower end 6a of the connecting part 6 is located below the fixing part 3. The lower end 6a of the connecting part 6 is as follows: Figure 5 As shown, when not connected to the plug 200, it is located below the lower end 5a of the connection part 5.

[0021] Connecting parts 5 and 6 are arranged adjacent to each other but not touching each other. In the state where they are not connected to the plug 200, as... Figure 2 From the frontal view shown, they overlap.

[0022] The guide portions 7 are provided in pairs, extending from the opposite edges 21a of the window opening portion 21 in a direction that separates them. The upper ends of the guide portions 7 are as follows: Figure 2 As shown, it is located at the same position in the vertical direction as the upper end of the top part 2.

[0023] <Connector mounting method towards circuit board> The following is for reference only. Figures 9 to 12 The method of mounting the connector 1 toward the circuit board 100 according to the first embodiment of the present invention will be described in detail.

[0024] The circuit board 100 has a plurality of through holes 101, and conductive portions with circuit patterns (not shown) are present around the through holes 101 on the surface 100a.

[0025] Connector 1 is inserted from above into the insertion hole 101 of the circuit board 100, continuing until the fixing part 3 abuts against the conductive part of the circuit pattern (not shown) on the surface 100a of the circuit board 100. Furthermore, connector 1 is mounted on the circuit board 100 by connecting and fixing the fixing part 3 to the conductive part of the circuit pattern on the surface 100a of the circuit board 100 using soldering or the like. Connector 1 is already mounted on the circuit board 100... Figure 7 and Figure 8 In the state shown, the lower end 5a of the connecting portion 5 and the lower end 6a of the connecting portion 6 are located below the back surface 101b of the circuit board 100.

[0026] The connector 1 is installed on the circuit board 100 by inserting it into each insertion hole 101 using the aforementioned method. In this way, a plurality of connectors 1 are installed on the circuit board 100.

[0027] The number of connectors 1 mounted on the circuit board 100 is shown here as 6 as an example. Furthermore, the number of connectors 1 mounted on the circuit board is not limited to 6; one or more connectors 1 may be mounted.

[0028] <Connector Action> The following also refers to Figures 9 to 12 The operation of the connector 1 according to the first embodiment of the present invention will be described in detail.

[0029] A circuit board 150 with multiple plugs 200 installed is prepared in advance, and a circuit board 100 with the same number of connectors 1 as the plugs 200 is installed.

[0030] First, the connector 201 of the plug 200 mounted on the circuit board 150 is inserted from above into the window 21 of the connector 1 mounted on the circuit board 100.

[0031] At this time, if the connecting part 201 is significantly offset from the connector 1 in the front-rear direction, the downward movement of the connector 1 can be restricted by the top part 2, which is abutted against by the connecting part 201, thus preventing plastic deformation of the connector 1. Furthermore, if the connecting part 201 is offset from the connector 1 in the left-right direction, the connecting part 201 abuts against the guide part 7, which guides the insertion towards the window hole 21. By extending the guide part 7 in a direction separating it from the edge 21a of the window hole 21, even if the positional offset of the connecting part 201, which has detached from the window hole 21, is large in the left-right direction, the connecting part 201 can be guided to the window hole 21.

[0032] The connecting part 201 moves downward through the through window hole 21 and abuts against the connecting part 5 and the connecting part 6.

[0033] Furthermore, connecting parts 5 and 6 move further downward via connecting part 201, elastically deforming in the direction of separation. When connecting part 201 experiences a positional shift, such as... Figure 10 and such Figure 11 As shown, it is connected to the connecting part 5 and the connecting part 6 at approximately the center of the window opening part 21.

[0034] At this time, by positioning the lower ends 5a of the connecting portion 5 and 6a of the connecting portion 6 below the pair of fixing portions 3, the connecting portions 5 and 6 can be elastically deformed without interfering with the circuit board 100. Furthermore, by making the connecting portions 5 and 6 overlap each other in a frontal view when not connected to the connecting portion 201, the contact pressure between the connecting portion 201 and the connecting portions 5 and 6 can be increased, ensuring a reliable connection between the connecting portion 201 and the connecting portions 5 and 6. Moreover, by forming a double fork between the drooping portion 41 and the opposing portion 42 and providing the connecting portions 5 and 6 between the double forks, the connecting portions 5 and 6 will not interfere with the drooping portion 41 and the opposing portion 42 when elastically deformed, and the connecting portion 201 will not interfere with the drooping portion 41 and the opposing portion 42.

[0035] Furthermore, if the connecting part 201 is displaced in the left-right direction due to vibration or other factors in the elastic deformation direction of the connecting part 5 and the connecting part 6, the load is applied from the connecting part 201 to the floating part 4 via the connecting part 5 or the connecting part 6.

[0036] For example, such as Figure 12 As shown, when the connecting part 201 deviates from the connecting part 5, a larger load is applied to the pair of floating parts 4 via the connecting part 5. Figure 12 The floating part 4 on the right side. At this time, in the floating part 4 on the right side, the downward part 41 faces as... Figure 12The middle part undergoes elastic deformation in the right direction, and along with this action, the opposing part 42 also undergoes elastic deformation in the right direction via the folding part 43 to absorb the load applied from the connecting part 201.

[0037] Furthermore, in the case where the connecting part 201 deviates from the connecting part 6, a larger load will be applied to the pair of floating parts 4 via the connecting part 5. Figure 12 The floating part 4 on the left side. At this time, in the floating part 4 on the left side, the hanging part 41 faces as... Figure 12 The middle part undergoes elastic deformation in the left direction, and along with this action, the opposing part 42 also undergoes elastic deformation in the left direction via the folding part 43 to absorb the load applied from the connecting part 201.

[0038] At this time, by making the length of the vertical portion 41 and the opposing portion 42 in the width direction shorter than the length of the fixed portion 3 in the width direction, the load applied from the connecting portion 201 can be concentrated on the floating portion 4 and will be applied to the fixed portion 3 as little as possible.

[0039] In this way, the load applied from the connecting part 201 to the connector 1 can be significantly reduced and applied directly to the fixing part 3. Therefore, it is possible to prevent the solder connecting the fixing part 3 to the conductive part of the circuit board 100 from peeling off, and to maintain a stable electrical connection between the connecting part 201 and the conductive part of the circuit board 100.

[0040] Furthermore, in the left-right direction, if the position of the connecting part 201 that is disengaged from the window opening part 21 is significantly offset, and the connecting part 201 is guided by the guide part 7 to pass through the window opening part 21, the floating part 4 can absorb the large load applied from the connecting part 201 to the connecting part 5 or the connecting part 6.

[0041] Furthermore, by providing the floating part 4, the guide part 7 can be extended in a direction that separates from the edge 21a of the window hole part 21, so that even if the connecting part 201 has a large positional offset in the left and right directions, the connecting part 201 can still be connected to the connector 1.

[0042] Furthermore, by forming the floating part 4 into a V-shape when viewed from the front, the entire floating part 4 can absorb the load applied from the connecting part 201 to the connecting part 5 or the connecting part 6.

[0043] Thus, according to this embodiment, a pair of fixing portions 3 are fixed and connected to the conductive portion of the circuit board 100, a pair of floating portions 4 are respectively connected to the top portion 2 and the pair of fixing portions 3, and a connecting portion 5 and a connecting portion 6 are connected to the connecting portion 201 of the plug 200 through the window portion 21. The pair of floating portions 4 each have a downwardly extending portion 41 that is divided into two forks from the end 2a and end 2b of the top portion 2, a pair of opposing portions 42 that are respectively opposite to the downwardly extending portions 41 of the two forks, and a folding portion 43 that connects the lower end of the downwardly extending portion 41 to the lower end of the opposing portion 42. The pair of fixing portions 3 are bent outward from the upper end of the opposing portion 42. The connecting portions 5 and 6 are provided to extend downward from the end 2a and end 2b of the top portion 2 between the two forks of the downwardly extending portion 41. In this way, even if the position of the connecting portion 201 is offset when or after connecting with the connecting portion 201 of the plug 200, a stable electrical connection can be maintained.

[0044] Furthermore, according to this embodiment, by making the connecting part 5 and the connecting part 6 not abut against each other, when the connector 1 is plated, a plating layer can be reliably formed on the surfaces of the connecting part 5 and the connecting part 6.

[0045] (Second Implementation) <Connector Structure> The following is for reference only. Figure 13 and Figure 14 The structure of the connector 80 according to the second embodiment of the present invention will be described in detail.

[0046] Furthermore, in Figure 13 and Figure 14 In China, regarding Figures 1 to 6 Parts with the same structure are assigned the same drawing number and their descriptions are omitted.

[0047] The connector 80 is formed by punching and bending a metal plate into one piece, and the surface is plated. It has: a top part 2, a fixing part 3, a connecting part 5, a connecting part 6, a guiding part 7, and a floating part 14.

[0048] The fixing part 3 is provided in pairs and is formed by bending outward from the upper end of the opposing part 142, which will be described later, of the floating part 14.

[0049] A pair of floating parts 14 are provided at the left and right positions of the top part 2, respectively connecting the top part 2 to a pair of fixed parts 3 and allowing for elastic deformation. The floating parts 14, as shown in... Figure 14 The frontal view shown is U-shaped. Specifically, the floating part 14 has a hanging part 141, an opposing part 142, and a folding part 143.

[0050] The lower portion 141 is bifurcated from the ends 2a and 2b of the aforementioned top portion 2 and extends downward. The length of the lower portion 141 in the width direction (y-axis direction) is shorter than the length of the fixed portion 3 in the width direction.

[0051] The opposing portions 142 are a pair, extending downward from the inner end of the fixing portion 3 into a double fork, and opposing the downward-hanging portion 141 of the double fork. The pair of opposing portions 142 are connected by the fixing portion 3. The opposing portions 142 extend in a manner parallel to the downward-hanging portion 141. In the opposing portions 142, the length in the width direction (y-axis direction) is shorter than the length in the width direction of the fixing portion 3.

[0052] The folding portion 143 connects the lower end of the hanging portion 141 to the lower end of the opposing portion 142.

[0053] The connecting part 5 is provided between the two forks of the hanging part 141, extending downward from the end 2a of the top part 2.

[0054] The connecting part 6 is provided between the two forks of the hanging part 141, extending downward from the end 2b of the top part 2 and connecting at the lower end 6a.

[0055] Furthermore, the mounting method and operation of the connector 80 toward the circuit board 100 in this embodiment are the same as the mounting method of the connector 1 toward the circuit board 100, and the description is omitted here.

[0056] Thus, according to this embodiment, the circuit includes a pair of fixing portions 3 fixed and connected to the conductive portion of the circuit board 100, a pair of floating portions 14 connecting the top portion 2 to the pair of fixing portions 3 respectively, and connecting portions 5 and 6 connected to the connecting portion 201 of the plug 200 of the insertion window portion 21. The pair of floating portions 14 each have a downwardly extending portion 141 that branches into two forks from the ends 2a and 2b of the top portion 2, and a vertical portion 141 that is respectively opposed to the downwardly extending portion 141 of the two forks. A pair of opposing portions 142 and a folding portion 143 connecting the lower end of the hanging portion 141 to the lower end of the opposing portion 142; a pair of fixing portions 3 bending outward from the upper end of the opposing portion 142; and connecting portions 5 and 6 extending downward from the ends 2a and 2b of the top portion 2 between the two prongs of the hanging portion 141. In this way, even if the position of the connecting portion 201 shifts when or after connecting with the connecting portion 201 of the plug 200, a stable electrical connection can be maintained.

[0057] (Third Implementation) <Connector Structure> The following is for reference only. Figure 15 and Figure 16The structure of the connector 90 according to the third embodiment of the present invention will be described in detail.

[0058] Furthermore, in Figure 15 and Figure 16 In China, regarding Figures 1 to 6 Parts with the same structure are assigned the same drawing number and their descriptions are omitted.

[0059] The connector 90 is formed by stamping and bending a metal plate into one piece, and the surface is plated. It has: a top part 2, a fixing part 3, a connecting part 5, a connecting part 6, a guiding part 7, and a floating part 24.

[0060] The fixing part 3 is provided in pairs and is formed by bending outward from the lower end of the protrusion 244 outside the floating part 24 (described later).

[0061] A pair of floating parts 24 are provided at the left and right positions of the top part 2, respectively connecting the top part 2 to a pair of fixed parts 3 and capable of elastic deformation. The floating parts 24, as shown in... Figure 16 The frontal view shown is U-shaped. Specifically, the floating part 24 has a hanging part 241, an opposing part 242, and a folding part 243.

[0062] The lower portion 241 is bifurcated from the ends 2a and 2b of the aforementioned top portion 2 and extends downward. The length of the lower portion 241 in the width direction (y-axis direction) is shorter than the length of the fixed portion 3 in the width direction.

[0063] The opposing portions 242 are a pair, extending downward from the inner end of the fixing portion 3 in a double-forked manner, and opposing the hanging portion 241 of the double forks. The pair of opposing portions 242 are connected by the fixing portion 3. The opposing portions 242 extend parallel to the hanging portion 241. The length of the opposing portion 242 in the width direction is shorter than the length of the fixing portion 3 in the width direction. The opposing portion 242 has a protrusion 244 that protrudes upward from the fixing portion 3. The protrusion 244 is in the shape of an inverted U in a frontal view.

[0064] The folding part 243 connects the lower end of the hanging part 241 to the lower end of the opposing part 242.

[0065] The connecting part 5 is provided between the two forks of the hanging part 241, extending downward from the end 2a of the top part 2.

[0066] The connecting part 6 is provided between the two forks of the hanging part 241, extending downward from the end 2b of the top part 2 and connecting at the lower end 6a.

[0067] Furthermore, the mounting method of the connector 90 toward the circuit board 100 in this embodiment is the same as the mounting method of the connector 1 toward the circuit board 100, and the description is omitted here.

[0068] <Connector Action> The operation of the connector 90 according to the third embodiment of the present invention will be described in detail below.

[0069] When the connecting part 201 is displaced in the left-right direction due to vibration or other factors, the load is applied from the connecting part 201 to the floating part 24 via the connecting part 5 or the connecting part 6.

[0070] For example, in the case where the connection 201 deviates from the connection 5, a larger load is applied to the pair of floating parts 24 via the connection 5. Figure 16 The floating part 24 on the right side. At this time, in the floating part 24 on the right side, the hanging part 241 faces as... Figure 16 The spring undergoes elastic deformation in the right direction, and along with this action, the opposing portion 242 also undergoes elastic deformation in the right direction via the folding portion 243, absorbing the load applied from the connecting portion 201. Furthermore, by providing the protrusion 244 in the opposing portion 242, a sufficient spring span can be obtained in the floating portion 24, thus allowing the floating portion 24 to absorb a larger load.

[0071] Furthermore, in the case where the connecting part 201 deviates from the connecting part 6, a larger load will be applied to the pair of floating parts 24 via the connecting part 5. Figure 16 The floating part 24 on the left side. At this time, in the floating part 24 on the left side, the hanging part 241 faces as... Figure 16 The spring undergoes elastic deformation in the left direction, and along with this action, the opposing portion 242 also undergoes elastic deformation in the left direction via the folding portion 243, absorbing the load applied from the connecting portion 201. Furthermore, by providing the protrusion 244 in the opposing portion 242, a sufficient spring span can be obtained in the floating portion 24, thus allowing the floating portion 24 to absorb a larger load.

[0072] Furthermore, the actions of connector 90 other than those mentioned above are the same as those of connector 1, so the description is omitted here.

[0073] Thus, according to this embodiment, a pair of fixing portions 3 are provided to fix and connect to the conductive portion of the circuit board 100, a pair of floating portions 24 are provided to connect the top portion 2 to the pair of fixing portions 3 respectively, and connecting portions 5 and 6 are provided to connect to the connecting portion 201 of the plug 200 of the insertion window portion 21. The pair of floating portions 24 each have a downwardly extending portion 241 that is divided into two forks from the ends 2a and 2b of the top portion 2, and the downwardly extending portion 241 is respectively opposed to the two forks. A pair of opposing portions 242 and a folding portion 243 connecting the lower end of the hanging portion 241 to the lower end of the opposing portion 242; a pair of fixing portions 3 bending outward from the upper end of the opposing portion 242; and connecting portions 5 and 6 extending downward from the ends 2a and 2b of the top portion 2 between the two prongs of the hanging portion 241. In this way, even if the position of the connecting portion 201 shifts when or after connecting with the connecting portion 201 of the plug 200, a stable electrical connection can be maintained.

[0074] Furthermore, in this embodiment, the floating part 24 is formed into a U-shape when viewed from the front, but it is not limited to this and the floating part can also be formed into a V-shape when viewed from the front.

[0075] (Fourth Implementation) <Connector Structure> The following is for reference only. Figure 17 and Figure 18 The structure of the connector 95 according to the fourth embodiment of the present invention will be described in detail.

[0076] Furthermore, in Figure 17 and Figure 18 In China, regarding Figures 1 to 6 Parts with the same structure are assigned the same drawing number and their descriptions are omitted.

[0077] The connector 95 is formed by punching and bending a metal plate into one piece, and the surface is plated. It has: a top part 2, a fixing part 3, a connecting part 5, a connecting part 6, a guiding part 7, and a floating part 34.

[0078] The fixing part 3 is formed by bending outward from the upper end of the inner opposing part 346, which will be described later, of the floating part 34.

[0079] The floating part 34 is provided on the left and right sides of the top part 2, respectively connecting the top part 2 to a pair of fixed parts 3 and being elastically deformable. From a frontal view, the floating part 34 is V-shaped. Specifically, the floating part 34 includes a hanging part 341, an opposing part 342, and a folding part 343.

[0080] The lower portion 341 is bifurcated from the ends 2a and 2b of the aforementioned top portion 2 and extends downward. The length of the lower portion 341 in the width direction (y-axis direction) is shorter than the length of the fixed portion 3 in the width direction.

[0081] The opposing portions 342 are a pair, extending downward from the inner end of the fixing portion 3 into a double fork, and opposing the downward-hanging portion 341 of the double fork. The pair of opposing portions 342 are connected by the fixing portion 3. The length of the opposing portion 342 in the width direction is shorter than the length of the fixing portion 3 in the width direction.

[0082] Specifically, the opposing portion 342 includes: an outer opposing portion 344, a central opposing portion 345, an inner opposing portion 346, an upper folding portion 347, and a lower folding portion 348.

[0083] The outer opposing portion 344 extends upward from the folded portion 343.

[0084] The central opposing portion 345 is positioned between the outer opposing portion 344 and the inner opposing portion 346.

[0085] The inner opposing part 346 is located inside the central opposing part 345, and its upper end is connected to the fixing part 3.

[0086] The upper folding portion 347 connects the upper end of the outer opposing portion 344 with the upper end of the central opposing portion 345.

[0087] The lower folding portion 348 connects the lower end of the central opposing portion 345 to the lower end of the inner opposing portion 346.

[0088] The opposing portion 342 has a hairpin shape formed by bending along the front-back direction through the outer opposing portion 344, the central opposing portion 345, and the upper folding portion 347. The opposing portion 342 also has a hairpin shape formed by bending along the front-back direction through the central opposing portion 345, the inner opposing portion 346, and the lower folding portion 348. Finally, the opposing portion 342 has a serpentine shape formed along the front-back direction through the outer opposing portion 344, the central opposing portion 345, the inner opposing portion 346, the upper folding portion 347, and the lower folding portion 348.

[0091] The connecting part 6 is provided between the two forks of the hanging part 341, extending downward from the end 2b of the top part 2 and connecting at the lower end 6a.

[0092] Furthermore, the mounting method of the connector 95 toward the circuit board 100 in this embodiment is the same as the mounting method of the connector 1 toward the circuit board 100, and the description is omitted here.

[0093] <Connector Action> The operation of the connector 95 according to the fourth embodiment of the present invention will be described in detail below.

[0094] When the connecting part 201 is displaced in the left-right direction due to vibration or other factors, the load is applied from the connecting part 201 to the floating part 34 via the connecting part 5 or the connecting part 6.

[0095] For example, in the case where the connection 201 deviates from the position of the connection 5, a larger load is applied to the pair of floating parts 34 via the connection 5. Figure 18 The floating part 34 is located on the front side. At this time, the downward-hanging part 341 of the floating part 34 on the front side faces... Figure 18 The part undergoes elastic deformation in the forward direction, and along with this action, the opposing part 342 also folds towards the center via the folding part 343. Figure 18 The spring undergoes elastic deformation in the forward direction to absorb the load applied from the connecting portion 201. Furthermore, by forming the opposing portion 342 into a shape in which the outer opposing portion 344, the central opposing portion 345, the inner opposing portion 346, the upper folding portion 347, and the lower folding portion 348 snake along the front-back direction, a sufficient spring span can be obtained in the floating portion 34. Therefore, a large load can be absorbed by the floating portion 34.

[0096] Furthermore, in the case where the connecting part 201 deviates from the connecting part 6, a larger load will be applied to the pair of floating parts 34 via the connecting part 5. Figure 18 The floating part 34 on the left side. At this time, in the floating part 34 on the deep side, the hanging part 341 faces as... Figure 18 The inner part undergoes elastic deformation in the deep direction, and along with this action, the opposing part 342 also moves towards the center via the folding part 343. Figure 18 The spring undergoes elastic deformation in its deep direction to absorb the load applied from the connecting portion 201. Furthermore, by forming the opposing portion 342 into a shape in which the outer opposing portion 344, the central opposing portion 345, the inner opposing portion 346, the upper folded portion 347, and the lower folded portion 348 snake along the front-back direction, a sufficient spring span can be obtained in the floating portion 34. Therefore, a large load can be absorbed by the floating portion 34.

[0097] Furthermore, the other actions of connector 95 are the same as those of connector 1, so the description is omitted here.

[0098] Thus, according to this embodiment, a pair of fixing portions 3 are fixed and connected to the conductive portion of the circuit board 100, a pair of floating portions 34 are respectively connected to the top portion 2 and the pair of fixing portions 3, and a connecting portion 5 and a connecting portion 6 are connected to the connecting portion 201 of the plug 200 of the insertion window portion 21. The pair of floating portions 34 respectively have a downwardly extending portion 341 that is divided into two forks from the ends 2a and 2b of the top portion 2, a pair of opposing portions 342 that are respectively opposite to the downwardly extending portion 341 of the two forks, and a connecting portion 5 and a connecting portion 6 that are connected to the top portion 200 of the plug 200 of the insertion window portion 21. The lower end of the drooping portion 341 is connected to the lower end of the outer opposing portion 344 of the opposing portion 342 by a folded portion 243. A pair of fixing portions 3 are bent outward from the upper end of the inner opposing portion 346 of the opposing portion 342. The connecting portion 5 and the connecting portion 6 are provided to extend downward from the end 2a and end 2b of the top portion 2 between the two prongs of the drooping portion 341, so that even if the position of the connecting portion 201 is offset when or after connecting with the connecting portion 201 of the plug 200, a stable electrical connection can be maintained.

[0099] Furthermore, in this embodiment, the opposing portion 342 of the floating portion 34 is formed in a serpentine shape along the front-back direction, but it is not limited to this and can also be formed in a serpentine shape along the left-right direction.

[0100] Furthermore, in this embodiment, the opposing portion 342 of the floating portion 34 is formed into a hairpin-shaped and serpentine shape, but it is not limited to this, and can also be formed into any shape such as an M-shape and a serpentine shape.
