[0032] Figure 22 The schematic diagram illustrates an example of a connector according to Patent Document 1. Specific Implementation The specific embodiments to which the present invention applies will now be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments. Furthermore, for clarity, the following description and drawings will be appropriately simplified.

[0034] Naturally, Figure 1 The right-hand XYZ coordinates shown in the accompanying drawings are for illustrative purposes only and do not indicate the actual positions of the connectors 100 and 200, which will be described below, during use. Generally, the X-axis direction refers to the mating direction, which is the mating direction for the connectors 100 and 200 (described later) to mat with an object connector (not shown in the figures). Furthermore, the Y-axis direction is the pitch direction, the Z-axis direction is the vertical direction, and the XY plane is a horizontal plane; these are common to all the figures.

[0035] <First Embodiment> The following will refer to Figures 1 to 10 The first embodiment of the present invention will be described.

[0036] Connector 100 can be mounted to substrate 300. When connector 100 is mounted to substrate 300, connector 100 is mounted on mounting surface 302 of substrate 300. For example, substrate 300 is a printed circuit board, such as a rigid substrate. Substrate 300 includes a plurality of gaskets 301. The plurality of gaskets 301 are disposed on mounting surface 302 and arranged in a spacing direction. In a first embodiment, the plurality of gaskets 301 are arranged in two rows. Substrate 300 may include a concave surface 303A, which, when viewed from above, is further recessed at end face 303. Concave surface 303A may have a shape, for example, capable of accommodating connector 100. A further recessed portion 304 may be provided on concave surface 303A. Hole 306 and female thread 307 are provided on mounting surface 302. Hole 306 extends from mounting surface 302 to rear end 305 and penetrates substrate 300.

[0037] Connector 100 is capable of mating with the object connector.

[0038] like Figures 1 to 3 As shown, connector 100 includes: a housing 110, a contact assembly 120, an insulator 150, and a screw locking portion 130. Connector 100 may include one or more screw locking portions 130.

[0039] The outer cover 110 holds the contact assembly 120. For example, the outer cover 110 may be made of resin or metal. Specifically, the outer cover 110 includes an outer cover body 111 and claws 112. The outer cover 110 may include one or more claws 112.

[0040] The outer casing 111 houses the contact assembly 120 and the insulator 150. The contact assembly 120 and the insulator 150 can be integrated together. The contact assembly 120 is embedded and molded into the insulator 150 and integrated therewith. The outer casing 111 is a substantially cylindrical body surrounding the contact assembly 120 and the insulator 150. The outer casing 111 includes: a mating opening 111A, a substrate-side opening 111B, and a substrate-side end portion 111C. When the connector 100 is mated with a target connector, the mating opening 111A contacts the target connector. When the connector 100 is mounted on the substrate 300, the substrate-side opening 111B faces the end face 303 or the concave face 303A. When the connector 100 is mounted on the substrate 300, the substrate-side end portion 111C extends from the upper part of the substrate-side opening 111B toward the substrate 300 and faces the mounting surface 302.

[0041] A claw 112 may be disposed at the substrate-side end 111C of the outer cover 111. The claw 112 and the outer cover 111 may be integrally formed. The claw 112 includes a claw body 113 and a protrusion 114. The claw 112 may be bent and extended, for example, in a substantially J-shape. The claw body 113 extends from the outer cover 111 toward the substrate 300 in the outer diameter direction of the outer cover 111. Figure 1 The protrusion 114 protrudes from the distal end of the claw body 113 in the direction of the X111 axis of the outer cover 111. Each claw 112 may further include an extension 114A. The extension 114A extends along the X111 axis of the outer cover 111 from the substrate-side end 111C or the root of the claw body 113. For example, the claw body 113, the protrusion 114, and the extension 114A may extend in a substantially C-shape or a substantially U-shape.

[0042] Contact group 120 includes contact rows 120A and 120B arranged in a spacing direction (Y-axis direction in this example). Contact row 120A is disposed above contact row 120B. Contact row 120A includes a plurality of contacts 121A. Contact row 120B includes a plurality of contacts 121B. Each contact 121A and contact 121B can elastically deform in a vertical direction (Z-axis direction in this example). Each contact 121A and contact 121B can be a rod-shaped body made of conductive material. Contact 121A and contact 121B respectively include contact portion 121a and contact portion 121b, which abut against corresponding pads 301 when connector 100 is mounted to substrate 300. Figure 2 As shown, when connector 100 is detached from substrate 300, contact portion 121a and protrusion 114 are separated by a distance LL. The distance LL is less than... Figure 1 The thickness TT of the substrate 300 shown.

[0043] For example, insulator 150 is made of a resin material with insulating properties. Insulator 150 surrounds a portion of contact assembly 120. Insulator 150 insulates contacts 121A and 121B. Contacts 121A and 121B of contact assembly 120 extend from insulator 150 in the mating direction (in this example, the X-axis direction). Figure 2 As shown, the insulator 150 includes a protrusion 151. The protrusion 151 protrudes from the substrate-side opening 111B of the outer cover 111 in the mating direction. The protrusion 151 may be disposed between the outer cover 111 and the claw 112.

[0044] like Figures 1 to 3 As shown, the screw locking portion 130 extends from the outer cover 111. The screw locking portion 130 and the outer cover 111 can be integrally formed. When the connector 100 is mounted on the mounting surface 302 of the substrate 300, the screw locking portion 130 can extend along the mounting surface 302 thereon. Specifically, the screw locking portion 130 can extend in the spacing direction. Each screw locking portion 130 includes a through hole 130A. The screw locking portion 130 can be locked to the substrate 300 by a male screw 131. By using the through hole 130A of the screw locking portion 130 to lock the male screw 131 to the female thread 307, the screw locking portion 130 can be locked to the substrate 300. The screw locking portion 130 serves as a coupling portion, functioning to allow the outer cover 110 to be installed or removed, and is coupled to the substrate 300.

[0045] <Method> Next, a method for mounting the connector 100 onto the substrate 300 will be described.

[0046] like Figure 4 and Figure 5 As shown, the claws 112 of the outer casing 110 of the connector 100 are inserted into the holes 306 of the substrate 300 (step ST11). Specifically, the connector 100 is positioned at an angle such that the axis X111 of the outer casing 111 intersects 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 is received in the holes 306. The protrusion 114 protrudes from the holes 306 toward the rear end 305. Further, Figure 2 The contact portions 121a of the plurality of contact members 121A and the contact portions 121b of the plurality of contact members 121B shown are pushed together. Figure 1 The plurality of corresponding pads 301 are shown. The extension 114A abuts against the mounting surface 302, which can prevent the outer cover 111 from moving excessively toward the base plate 300. Accordingly, it is possible to prevent or reduce the plurality of contacts 121A and the plurality of contacts 121B from pushing against the plurality of corresponding pads 301 and buckling.

[0047] Next, as Figure 6 As shown, the connector 100 is positioned such that the axis X111 of the outer cover 111 is inclined along or parallel to the mounting surface 302 of the substrate 300 (step ST12). Figure 4 The screw locking part 130 and the female thread 307 of the mounting surface 302 shown are facing each other or in contact with each other. Therefore, Figure 5 The claw 113 shown passes through the hole 306 and penetrates the substrate 300. Further, the protrusion 114 extends along the rear end 305. That is, the claw 112 grips the substrate 300. Further, Figure 2 The plurality of contacts 121A and the plurality of contacts 121B shown are pushed together. Figure 1 The plurality of corresponding pads 301 shown are elastically deformed and contact the plurality of corresponding pads 301.

[0048] Finally, as Figure 7 and Figure 8 As shown, the male screw 131 is tightened into the female thread 307 (step ST13). A known screwdriver can be used to tighten the male screw 131 into the female thread 307. Therefore, the screw-locking part 130 and the substrate 300 are locked together by the male screw 131. That is, the screw-locking part 130 can couple the outer cover 110 to the substrate 300. Further, Figure 2 The plurality of contacts 121A and the plurality of contacts 121B shown maintain with Figure 1 The plurality of corresponding pads 301 contacts are shown.

[0049] From the above explanation, as Figures 8 to 10 As shown, connector 100 is mounted on substrate 300. Figure 2 The plurality of contacts 121A and the plurality of contacts 121B shown Figure 1 The plurality of corresponding pads 301 are shown, and are electrically connected to the plurality of corresponding pads 301. The substrate 300 equipped with the connector 100 can be used as a connector mounting plate.

[0050] Furthermore, when the connector 100 is mounted on the substrate 300, the protrusion 151 of the outer cover 110 engages with the recess 304 of the substrate 300. This ensures the accuracy of the connector 100's position in the pitch direction.

[0051] Regarding the method for removing the connector 100 from the substrate 300, each step in the above-described method for attaching the connector 100 to the substrate 300 can be performed in reverse order. That is, the male screw 131 is removed from the female thread 307, and the locking screw locking part 130 and the substrate 300 are released. Next, the position of the connector 100 is tilted such that the axis X111 of the outer cover 111 intersects the mounting surface 302 of the substrate 300. Finally, the claw 112 is removed from the hole 306. Therefore, the connector 100 can be removed from the substrate 300.

[0052] The methods described above for attaching the connector 100 to the substrate 300 and for removing the connector 100 from the substrate 300 do not require excessive skill or special tools, such as soldering or desoldering. That is, these methods can be performed using widely available tools or by the user's hand. Accordingly, it is easy to attach the connector 100 to the substrate 300 and to remove the connector 100 from the substrate 300.

[0053] <Second Embodiment> Next, refer to Figures 11 to 21 The second embodiment of the present invention will be described.

[0054] In addition to the connector 200 including the rod 140, the base plate 170, and the outer cover 210, the connector 200 has the same... Figure 1 The connector 100 shown has the same configuration. (As shown) Figures 11 to 13 As shown, connector 200 includes a rod 140, a base plate 170, and an outer cover 210. The rod 140 and the base plate 170 function as coupling portions that removably couple the outer cover 210 to the substrate 300.

[0055] like Figure 11 and Figure 12 As shown, the rod 140 is a rod extending into a substantially U-shape. The rod 140 can be made of a flexible or elastically deformable material. The rod 140 includes a shaft 141, a cam portion 142, and a grip portion 143. The shaft 141, cam portion 142, and grip portion 143 are connected together in this order from one end of the rod 140 to the other. The rod 140 is held in place by a bearing 115 of the outer casing 210, described later, to rotate about the shaft 141. The cam portion 142 extends outward in a direction separate from the shaft 141 on the plane of rotation of the rod 140 (in this example, the ZX plane). The grip portion 143 may extend in the plane of rotation of the rod 140 in a direction opposite to the outward extension direction of the cam portion 142. The grip portion 143 may have a shape, for example, that allows a user to hold it.

[0056] like Figure 13As shown, the base plate 170 includes: an outer cover holding portion 171, a locking portion 172, and a cam holding portion 173. The outer cover holding portion 171 is a plate-shaped portion extending in the space surrounded by the concave surface 303A of the substrate 300. The outer cover holding portion 171 may have a shape capable of holding the outer cover 210, for example. The locking portion 172 is a plate-shaped portion extending in the spacing direction from both sides of the outer cover holding portion 171. The locking portion 172 is locked to the substrate 300 by male screws 132. The cam holding portion 173 is a plate-shaped portion extending from the locking portion 172 toward the end face 303. The cam holding portion 173 may have a shape such that when the cam portion 142 pushes against the cam holding portion 173, the cam holding portion 173 can hold the cam portion 142 in a rotatable manner. Specifically, the cam retainer 173 can be bent into a substantially C-shape in a plane perpendicular to the pitch direction (in this example, the ZX plane).

[0057] like Figure 11 and Figure 12 As shown, in addition to the outer cover 210 including: bearing 115, rod locking part 116, wall 117, and groove 118, the outer cover 210 has the same as... Figure 1 The outer cover 110 shown has the same configuration.

[0058] The bearing 115 holds the shaft 141 in a rotatable manner. The bearing 115 can extend vertically upward from the outer cover 111 (in this example, the positive direction of the Z-axis). The bearing 115 can be disposed in the outer cover 111 between the fitting opening 111A and the substrate-side opening 111B.

[0059] The rod locking portion 116 includes a wall 117 and a groove 118. The rod locking portion 116 may be provided on the outer cover 111, for example, at the substrate-side end 111C. The wall 117 protrudes in the mating 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 one side of the claw 112 relative to the wall 117. The groove 118 may have a shape, for example, capable of holding the gripping portion 143.

[0060] <Method> Next, a method for mounting the connector 200 onto the substrate 300 will be described.

[0061] like Figure 14 As shown, as described in step ST11 above, the claws 112 of the outer casing 210 of the connector 200 are inserted into the hole 306 of the substrate 300 (step ST21). As described in step ST12 above, the position of the connector 200 is tilted along or parallel to the mounting surface 302 of the substrate 300 with the axis X111 of the outer casing 111 of the connector 200 (step ST22).

[0062] Finally, as Figures 15 to 20 As shown, the rod 140 rotates about the shaft 141 towards the substrate side end 111C of the outer cover 111 (step ST23).

[0063] Specifically, by using the gripping part 143, the user applies force and rotates the lever 140. The lever 140 begins to rotate about the shaft 141 towards the base plate side end 111C of the outer cover 111, and the cam part 142 begins to rotate about the shaft 141 towards the cam retaining part 173. Figure 15 and Figure 17 As shown, the cam portion 142 extends from the shaft 141 in a direction substantially perpendicular to the mounting surface 302 of the substrate 300 on the plane in which the rod 140 rotates (in this example, the ZX plane), and pushes against the substrate 300 by the locking portion 172.

[0064] After the rotational movement of lever 140 is further carried out, as... Figure 18 and Figure 19 As shown, the gripping part 143 contacts the wall 117 of the rod locking part 116, and the cam part 142 approaches the cam retaining part 173. On the plane of rotation of the rod 140, the cam part 142 extends in a direction inclined relative to the vertical line Z1 of the mounting surface 302 of the base plate 300 passing through the shaft 141, and moves on the locking part 172.

[0065] After the rotational movement of lever 140 is further carried out, as... Figure 16 and Figure 20 As shown, the gripping portion 143 elastically deforms, extends in the engagement direction, and passes over the wall 117 of the rod locking portion 116. Then, the gripping portion 143 is secured in the groove 118. That is, the rod locking portion 116 locks the rod 140. Simultaneously, the cam portion 142 pushes against the cam holding portion 173 and is rotatably secured. Subsequently, the rod 140 rotates about the cam portion 142 and, via the shaft 141 and bearing 115, pushes the outer cover 111 of the outer cover 210 toward the substrate 300. Therefore, the outer cover 210 is coupled to the substrate 300.

[0066] As described above, connector 200 is mounted on substrate 300. Figure 21 The plurality of contacts 121A and the plurality of contacts 121B shown are pushed against and electrically connected to the plurality of corresponding pads 301. The substrate 300 on which the connector 200 is mounted can be used as a connector mounting plate.

[0067] Regarding the method for removing the connector 200 from the substrate 300, each step in the above-described method for mounting the connector 200 to the substrate 300 can be performed in reverse order. That is, the rod 140 rotates from the substrate-side end 111C of the outer cover 111 toward the fitting opening 111A about the shaft 141. The rod 140, which is locked by the rod locking part 116, is released, and the cam part 142 moves away from the cam holding part 173. Next, the position of the connector 200 is tilted such that the axis X111 of the outer cover 111 intersects the mounting surface 302 of the substrate 300. Finally, the claw 112 is removed from the hole 306. Therefore, the connector 200 can be removed from the substrate 300.

[0068] The methods described above for attaching the connector 200 to the substrate 300 and for removing the connector 200 from the substrate 300 do not require excessive skill or special tools, such as soldering or desoldering. That is, these methods can be performed using widely available tools or by the user's hand. Accordingly, the connector 200 can be easily attached to and detached from the substrate 300.

[0069] It should be noted that the present invention is not limited to the embodiments described above, and can be appropriately varied without departing from the spirit of the invention. For example, although a substrate 300 with a concave surface 303A is used in the first and second embodiments, substrates with other shapes, such as substrates with flat end faces and no concave surface, can be used instead.

[0070] The first and second embodiments can be combined by those skilled in the art according to their needs.

[0071] As will be apparent from the disclosure herein, embodiments of the invention can be modified in various ways. Such modifications should not be considered contrary to the spirit and scope of the invention, and it will be apparent to those skilled in the art that all such modifications are intended to be included within the scope of the following claims.
