[0015] The following describes specific embodiments to which the present invention is applied, with reference to the drawings. However, the present invention is not limited to the following embodiments. Also, for clarity of explanation, the following description and drawings have been simplified as appropriate.

[0016] It should be noted that, naturally, the right-handed XYZ coordinates shown in Figure 1 and other drawings are for convenience in explaining the positional relationships of the components and do not indicate the actual orientation of connectors 100, 200, etc., in use, as described later. Typically, the X-axis direction is the mating direction in which connectors 100, 200, described later, mate with the mating connector (not shown). Also, the Y-axis direction is the pitch direction, the Z-axis direction is the vertical direction, and the XY plane is the horizontal plane, which are common to all drawings.

[0017] <First Embodiment> Hereinafter, a first embodiment of this disclosure will be described with reference to Figures 1 to 10.

[0018] The connector 100 is mountable on the substrate 300. When the connector 100 is mounted on the substrate 300, it is mounted on the mounting surface 302 of the substrate 300. The substrate 300 is a printed circuit board, such as a rigid substrate. The substrate 300 has a plurality of pads 301. The plurality of pads 301 are arranged in the pitch direction and provided on the mounting surface 302. In the first embodiment, the plurality of pads 301 are arranged in two rows. When the mounting surface 302 is viewed from above, the substrate 300 may have a recessed surface 303A that is further recessed at the end surface 303. The recessed surface 303A may have a shape that can accommodate the connector 100. The recessed surface 303A may have a further recessed recess 304. The mounting surface 302 is provided with holes 306 and female threads 307. The holes 306 extend from the mounting surface 302 to the back surface 305 and penetrate the substrate 300.

[0019] Connector 100 is matable with the mating connector.

[0020] As shown in Figures 1 to 3, the connector 100 comprises a shell 110, a contact group 120, an insulator 150, and a screw fastening portion 130. The connector 100 may have one or more screw fastening portions 130.

[0021] The shell 110 holds the contact group 120. The shell 110 may be made of, for example, a resin material or a metal material. Specifically, the shell 110 comprises a shell body 111 and claws 112. The shell 110 may have one or more claws 112.

[0022] The shell body 111 houses the contact group 120 and the insulator 150. The contact group 120 and the insulator 150 are preferably integrated. The contact group 120 is integrated with the insulator 150 by insert molding. The shell body 111 is a substantially cylindrical body that surrounds the contact group 120 and the insulator 150. The shell body 111 has a mating opening 111A, a substrate-side opening 111B, and a substrate-side end 111C. The mating opening 111A contacts the mating connector when the connector 100 is mated with the mating connector. The substrate-side opening 111B faces the end face 303 or the concave surface 303A when the connector 100 is mounted on the substrate 300. When the connector 100 is attached to the substrate 300, the substrate-side end 111C extends from the upper portion of the substrate-side opening 111B toward the substrate 300 and faces the mounting surface 302.

[0023] The claw 112 may be provided at the substrate-side end 111C of the shell body 111. The claw 112 and the shell body 111 may be integrally molded. The claw 112 comprises a claw body 113 and a projection 114. The claw 112 may be curved, for example, extending along a roughly J-shape. The claw body 113 protrudes from the shell body 111 toward the substrate 300 side (negative Z-axis direction in Figure 1) in the outer diameter direction of the shell body 111. The projection 114 protrudes from the tip of the claw body 113 in the direction in which the axis X111 of the shell body 111 extends. The claw 112 may further comprise an extension 114A. The extension 114A extends from the substrate-side end 111C or the base of the claw body 113 along the axis X111 of the shell body 111. The claw body 113, the projection 114, and the extension 114A may extend along a roughly C-shape or a roughly U-shape, for example.

[0024] The contact group 120 comprises contact rows 120A and 120B arranged in the pitch direction (here, the Y-axis direction). Contact row 120A is positioned above contact row 120B. Contact row 120A comprises multiple contacts 121A. Contact row 120B comprises multiple contacts 121B. Each contact 121A, 121B is preferably elastically deformable in the vertical direction (here, the Z-axis direction). Each contact 121A, 121B is preferably a rod-shaped body made of a conductive material. When the connector 100 is attached to the substrate 300, each contact 121A, 121B has contact portions 121a and 121b that press against each pad 301. As shown in Figure 2, when the connector 100 is removed from the substrate 300, a distance LL is left between the contact portion 121a and the projection 114. The distance LL is smaller than the thickness TT of the substrate 300 shown in Figure 1.

[0025] The insulator 150 is made of, for example, an insulating resin material. The insulator 150 encloses a portion of the contact group 120. The insulator 150 insulates the contacts 121A and 121B. The contacts 121A and 121B of the contact group 120 extend from the insulator 150 in the mating direction (in this case, the X-axis direction). As shown in Figure 2, the insulator 150 has a protrusion 151. The protrusion 151 protrudes from the substrate-side opening 111B of the shell body 111 in the mating direction. The protrusion 151 is preferably positioned between the shell body 111 and the claw 112.

[0026] As shown in Figures 1 to 3, the screw fastening portion 130 extends from the shell body 111. The screw fastening portion 130 and the shell body 111 may be integrally molded. When the connector 100 is mounted on the mounting surface 302 of the substrate 300, the screw fastening portion 130 may extend along the mounting surface 302. Specifically, the screw fastening portion 130 may extend in the pitch direction. The screw fastening portion 130 is provided with a through hole 130A. The screw fastening portion 130 can be fastened to the substrate 300 via a male screw 131. By tightening the male screw 131 through the through hole 130A of the screw fastening portion 130 into the female screw 307, the screw fastening portion 130 can be fastened to the substrate 300. The screw fastening portion 130 functions as a coupling portion that detachably connects the shell 110 to the substrate 300.

[0027] <Method> Next, we will explain how to attach the connector 100 to the circuit board 300.

[0028] As shown in Figures 4 and 5, the claws 112 of the shell 110 of the connector 100 are inserted into the holes 306 of the substrate 300 (step ST11). Specifically, the orientation of the connector 100 is tilted so that the axis X111 of the shell body 111 intersects with the mounting surface 302 of the substrate 300. The claws 112 are inserted into the holes 306 of the substrate 300. The claw body 113 fits into the hole 306. The projection 114 protrudes from the hole 306 toward the back surface 305. In addition, the contact portions 121a and 121b of the multiple contacts 121A and 121B shown in Figure 2 press against the multiple pads 301 shown in Figure 1. The extension portion 114A contacts the mounting surface 302, which can limit the movement of the shell body 111 toward the substrate 300. Therefore, it is possible to suppress buckling by preventing multiple contacts 121A and 121B from pressing against multiple pads 301.

[0029] Next, as shown in Figure 6, the orientation of the connector 100 is tilted (step ST12) so that the axis X111 of the shell body 111 is along or parallel to the mounting surface 302 of the substrate 300. The screw fastening portion 130 and the female thread 307 of the mounting surface 302 shown in Figure 4 face each other or come into contact. As a result, the claw body 113 shown in Figure 5 passes through the hole 306 and penetrates the substrate 300. Also, the projection 114 extends along the back surface 305. That is, the claw 112 hooks onto the substrate 300. In addition, the multiple contacts 121A and 121B shown in Figure 2 each press against the multiple pads 301 shown in Figure 1, elastically deform, and make contact.

[0030] Finally, as shown in Figures 7 and 8, the male screw 131 is fastened to the female screw 307 (step ST13). It is preferable to use a known screwdriver to fasten the male screw 131 to the female screw 307. This fastens the screw fastening portion 130 and the substrate 300 via the male screw 131. In other words, the screw fastening portion 130 can connect the shell 110 to the substrate 300. In addition, the multiple contacts 121A and 121B shown in Figure 2 each maintain contact with the multiple pads 301 shown in Figure 1.

[0031] As described above, the connector 100 is mounted on the circuit board 300 as shown in Figures 8 to 10. The multiple contacts 121A and 121B shown in Figure 2 each make contact with the multiple pads 301 shown in Figure 1, thereby making an electrical connection. The circuit board 300 to which the connector 100 is mounted can be used as a connector mounting board.

[0032] Furthermore, when the connector 100 is attached to the substrate 300, the protrusion 151 of the shell 110 fits into the recess 304 of the substrate 300. This ensures positional accuracy of the connector 100 in the pitch direction.

[0033] To remove the connector 100 from the circuit board 300, simply perform each step in the reverse order of the method for attaching the connector 100 to the circuit board 300 described above. That is, remove the male screw 131 from the female screw 307 to release the fastening between the screw fastening part 130 and the circuit board 300. Next, tilt the orientation of the connector 100 so that the axis X111 of the shell body 111 intersects with the mounting surface 302 of the circuit board 300. Finally, pull out the claw 112 from the hole 306. This will allow you to remove the connector 100 from the circuit board 300.

[0034] The methods described above for attaching the connector 100 to the circuit board 300 and for removing the connector 100 from the circuit board 300 do not require skilled work such as soldering or desoldering, nor do they require special tools. In other words, these methods can be performed using widely available tools and the user's own hands. Therefore, the connector 100 can be easily attached to and removed from the circuit board 300.

[0035] <Second Embodiment> Next, a second embodiment of the present disclosure will be described with reference to Figures 11 to 21.

[0036] Connector 200 has the same configuration as connector 100 shown in Figure 1, except that it includes a lever 140, a base plate 170, and a shell 210. As shown in Figures 11 to 13, connector 200 includes a lever 140, a base plate 170, and a shell 210. The lever 140 and the base plate 170 function as coupling parts that detachably connect the shell 210 to the substrate 300.

[0037] As shown in Figures 11 and 12, the lever 140 is a rod-shaped body extending in a roughly U-shape. The lever 140 may be made of a flexible or elastically deformable material. The lever 140 comprises a shaft 141, a cam portion 142, and a gripping portion 143. The shaft 141, cam portion 142, gripping portion 143, cam portion 142, and shaft 141 are connected in this order from one end to the other of the lever 140. The lever 140 is held to rotate around the shaft 141 by a bearing 115 of the shell 210, which will be described later. The cam portion 142 extends in a direction away from the shaft 141 in the plane in which the lever 140 rotates (here, the ZX plane). The gripping portion 143 may extend in the opposite direction to the direction in which the cam portion 142 extends in the plane in which the lever 140 rotates. The gripping portion 143 should preferably have a shape that allows the user to grip it.

[0038] As shown in Figure 13, the base plate 170 comprises a shell holding portion 171, a fastening portion 172, and a cam holding portion 173. The shell holding portion 171 is a plate-shaped portion that extends in the space enclosed by the concave surface 303A of the substrate 300. The shell holding portion 171 should have a shape capable of holding the shell 210. The fastening portion 172 is a plate-shaped portion that extends in the pitch direction from both sides of the shell holding portion 171 in the pitch direction. The fastening portion 172 fastens to the substrate 300 via a male screw 132. The cam holding portion 173 is a plate-shaped portion that extends from the fastening portion 172 toward the end face 303. The cam holding portion 173 should have a shape capable of rotatably holding the cam portion 142 when it presses against it. Specifically, the cam holding portion 173 should be bent in a roughly C-shape along a plane perpendicular to the pitch direction (here, the ZX plane).

[0039] As shown in Figures 11 and 12, the shell 210 has the same configuration as the shell 110 shown in Figure 1, except that it includes a bearing 115, a lever lock portion 116, a wall 117, and a groove 118.

[0040] The bearing 115 holds the shaft 141 so that it can rotate. The bearing 115 may extend vertically upward from the shell body 111 (in this case, in the positive Z-axis direction). The bearing 115 may be provided in the shell body 111 between the fitting opening 111A and the substrate-side opening 111B.

[0041] The lever lock portion 116 comprises a wall 117 and a groove 118. The lever lock portion 116 may be provided on the shell body 111, for example, on the substrate-side end 111C. The wall 117 protrudes in the fitting direction at the substrate-side end 111C. The groove 118 is recessed at the substrate-side end 111C. The groove 118 may be provided on the claw 112 side of the wall 117. The groove 118 may have a shape capable of holding the gripping portion 143.

[0042] <Method> Next, we will explain how to attach the connector 200 to the circuit board 300.

[0043] As shown in Figure 14, similar to step ST11 described above, the claws 112 of the shell 210 of the connector 200 are inserted into the holes 306 of the substrate 300 (step ST21). Similar to step ST12 described above, the orientation of the connector 100 is tilted so that the axis X111 of the shell body 111 of the connector 200 is aligned with or parallel to the mounting surface 302 of the substrate 300 (step ST22).

[0044] Finally, as shown in Figures 15 to 20, the lever 140 is rotated around the axis 141 toward the substrate-side end 111C of the shell body 111 (step ST23).

[0045] Specifically, the gripping portion 143 is gripped by the user, and force is applied by the user, causing the lever 140 to rotate. As the lever 140 begins to rotate around the shaft 141 toward the substrate-side end 111C of the shell body 111, the cam portion 142 begins to rotate around the shaft 141 toward the cam holding portion 173. As shown in Figures 15 and 17, in the plane around which the lever 140 rotates (here, the ZX plane), the cam portion 142 extends from the shaft 141 in a direction substantially perpendicular to the mounting surface 302 of the substrate 300 and presses against the substrate 300 via the fastening portion 172.

[0046] As the lever 140 rotates further, as shown in Figures 18 and 19, the gripping portion 143 reaches the wall 117 of the lever lock portion 116, and the cam portion 142 approaches the cam holding portion 173. In the plane in which the lever 140 rotates, the cam portion 142 extends in a direction inclined with respect to the perpendicular Z1 of the mounting surface 302 of the substrate 300 passing through the shaft 141, and moves on the fastening portion 172.

[0047] As the lever 140 rotates further, as shown in Figures 16 and 20, the gripping portion 143 elastically deforms and extends in the fitting direction, exceeding the wall 117 of the lever lock portion 116. The gripping portion 143 is then held in the groove 118. In other words, the lever lock portion 116 locks the lever 140. Simultaneously, the cam portion 142 presses against the cam holding portion 173 and is held in a rotatable position. Subsequently, the lever 140 rotates around the cam portion 142, pushing the shell body 111 of the shell 210 toward the substrate 300 via the shaft 141 and bearing 115. This connects the shell 210 to the substrate 300.

[0048] Based on the above, the connector 200 is mounted on the circuit board 300. The multiple contacts 121A and 121B shown in Figure 21 each press against the multiple pads 301 to make an electrical connection. The circuit board 300 with the connector 200 mounted can be used as a connector mounting board.

[0049] To remove the connector 200 from the circuit board 300, simply perform the steps in the reverse order of the method for attaching the connector 200 to the circuit board 300 described above. Specifically, rotate the lever 140 around the axis 141 from the circuit board side end 111C of the shell body 111 towards the mating opening 111A. Release the lock on the lever 140 by the lever lock part 116 and separate the cam part 142 from the cam holding part 173. Next, tilt the orientation of the connector 200 so that the axis X111 of the shell body 111 intersects with the mounting surface 302 of the circuit board 300. Finally, pull out the claw 112 from the hole 306. This will allow you to remove the connector 200 from the circuit board 300.

[0050] The methods described above for attaching the connector 200 to the circuit board 300 and for removing the connector 200 from the circuit board 300 do not require skilled work such as soldering or desoldering, nor do they require special tools. In other words, these methods can be performed using widely available tools and the user's own hands. Therefore, the connector 200 can be easily attached to and removed from the circuit board 300.

[0051] It should be noted that the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. For example, in the first and second embodiments, a substrate 300 having a concave surface 303A was used, but a substrate having other shapes, such as a substrate without a concave surface, i.e., a flat end face, may also be used.
