[0014] 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.

[0015] 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 the connector assemblies 500, 600, etc., in their usage state, as described later. Typically, the X-axis direction is the mating direction in which connectors 100 and 200, described later, mate with the mating connector (not shown). Also, the Y-axis direction is the pitch direction, the X-axis direction is the mating direction in which connectors 100 and 200, described later, mate, and the XY plane is the horizontal plane, which is common to all drawings.

[0016] <First Embodiment> Hereinafter, a first embodiment of this disclosure will be described with reference to Figures 1 to 19.

[0017] As shown in Figures 1 to 10, the connector assembly 500 comprises a connector 100 and a frame 300.

[0018] In the connector assembly 500, the connector 100 can be attached to and detached from the substrate 700 via the frame 300. When the connector 100 is attached to the substrate 700 via the frame 300, it is mounted on the mounting surface 701 of the substrate 700. The substrate 700 is, for example, a printed circuit board such as a rigid substrate. As shown in Figures 9 and 10, a plurality of pads 702 are provided on the mounting surface 701, arranged in the pitch direction. In the first embodiment, the plurality of pads 702 are arranged in two rows. When the mounting surface 701 is viewed from above, the substrate 700 may have a concave surface 704A that is further recessed at the end face 704. The end face 704 and the concave surface 704A may have a shape that follows the frame 300. The mounting surface 701 is provided with holes 703 that penetrate the substrate 700, positioning holes 705A and 705B. In the first embodiment, two holes 703 are arranged in the pitch direction with a predetermined distance between them. A concave surface 704A is provided between two holes 703. Positioning holes 705A and 705B are arranged in the pitch direction at predetermined intervals. Multiple pads 702 are provided between positioning holes 705A and 705B. The cross-sectional shape of positioning hole 705A is approximately circular, and the cross-sectional shape of positioning hole 705B is approximately oval, specifically an oval or rounded rectangle.

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

[0020] As shown in Figure 10, the connector 100 comprises a shell 110, a contact group 120, an insulator 130, a projection 111, and a lance 112. The connector 100 may also have at least one of the projection 111 and the lance 112.

[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 houses the contact group 120 and the insulator 130. The contact group 120 and the insulator 130 may be integrated. The contact group 120 is assembled and integrated with the insulator 130. The shell 110 is a substantially cylindrical body that surrounds the contact group 120 and the insulator 130.

[0022] The shell 110 has a mating opening 110A, a substrate-side opening 110B, and a substrate-side end 110C. The shell 110 has a top surface 110D, a bottom surface 110E, and sides 110F and 110G. The cross-sectional shape of the shell 110 is preferably approximately square. The corners formed by the intersection of the top surface 110D and the side 110F of the shell 110 may be rounded. Similarly, the corners formed by the intersection of the top surface 110D and the side 110G, the corners formed by the intersection of the bottom surface 110E and the side 110F, and the corners formed by the intersection of the bottom surface 110E and the side 110G may be rounded. The mating opening 110A contacts the mating connector when the connector 100 is mated with the mating connector.

[0023] 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 700, each contact 121A, 121B has contact portions 121a and 121b that press against each pad 702.

[0024] The insulator 130 is made of, for example, an insulating resin material. The insulator 130 encloses a portion of the contact group 120. The insulator 130 insulates the contacts 121A and 121B. The contacts 121A and 121B of the contact group 120 extend out of the insulator 130 in the mating direction (in this case, the X-axis direction).

[0025] The projections 111 protrude from the shell 110. In the first embodiment, the two projections 111 protrude in the fitting direction from one end and the other end of the substrate-side end 110C, respectively. The tip 111A of each projection 111 has an upwardly projecting arc-shaped or hemispherical surface.

[0026] The lance 112 is provided on the shell 110. Specifically, the lance 112 is provided on the sides 110F and 110G of the shell 110 and protrudes diagonally upward. The lance 112 is preferably made of an elastically deformable material. The lance 112 can be compressed in the pitch direction.

[0027] The shell 110, projection 111, and lance 112 are preferably integrated into a single unit. It is preferable to integrate the shell 110, projection 111, and lance 112 by press-forming a single sheet of metal.

[0028] The frame 300 can be installed on the substrate 700. As shown in Figure 9, the frame 300 comprises a projection receiving portion 301, a lance receiving portion 302, and a frame body 303.

[0029] The frame body 303 may extend along a roughly C-shape on the mounting surface 701 and conform to the shape of the connector 100. The frame body 303 comprises a central part 303A and side parts 303B and 303C. The side parts 303B and 303C extend in the same direction from both ends of the central part 303A. The side parts 303B and 303C may be spaced apart by more than the width of the shell 110 in the pitch direction. The central part 303A and side parts 303B and 303C may be arranged to enclose the connector 100.

[0030] The projection receiving portion 301 may have a recessed shape in the central portion 303A so as to be able to receive the projection 111. The two projection receiving portions 301 may be provided on the side portion 303B side of the central portion 303A and on the side portion 303C side of the central portion 303A, respectively.

[0031] The lance receiving portion 302 may have a recessed shape so as to be able to receive the lance 112. Two lance receiving portions 302 may be provided on the side portion 303B and the side portion 303C, respectively. Each lance receiving portion 302 comprises a projection 302A, a recess 302B, and a groove 302C. The projection 302A protrudes inward in the pitch direction. The recess 302B is provided below the projection 302A. The recess 302B is recessed outward in the pitch direction so as to be able to receive the lance 112. The groove 302C is provided in the projection 302A and has a recessed shape so as to be able to insert a tool.

[0032] The frame 300 may further include a hole 304. A bolt 310 is inserted through the holes 304 and 703 and fastened with a nut 320. This allows the frame 300 to be installed on the substrate 700. The frame 300 may further include positioning protrusions 305A and 305B. As shown in Figures 4 to 9, the positioning protrusions 305A and 305B are provided on the side portions 303B and 303C, respectively. The positioning protrusion 305A is a substantially cylindrical portion that protrudes from the side portion 303B toward the frame 300 (in this case, in the negative Z-axis direction). The positioning protrusion 305B is a substantially cylindrical portion that protrudes from the side portion 303C toward the frame 300.

[0033] <Method> Next, we will describe how to attach the connector 100 to the circuit board 700 via the frame 300.

[0034] Prior to this method, the frame 300 is pre-installed on the substrate 700. Specifically, as shown in Figures 9 and 11, bolts 310 are inserted through holes 304 in the frame 300 and holes 703 in the substrate 700 and fastened with nuts 320. Positioning protrusions 305A and 305B are inserted into positioning holes 705A and 705B, respectively. This allows for accurate positioning of the frame 300 relative to the substrate 700.

[0035] As shown in Figure 11, the orientation of the connector 100 is tilted (step ST1). Specifically, the orientation of the connector 100 is tilted so that the projection 111 is closer to the mounting surface 701 of the substrate 700.

[0036] Next, as shown in Figures 12 to 15, the connector 100 is moved toward the frame 300 while keeping the connector 100 tilted (step ST2). Furthermore, as shown in Figure 15, the projection 111 is inserted into the projection receiving portion 301.

[0037] Finally, while the projection 111 remains in contact with the projection receiving portion 301, the shell 110 is rotated toward the substrate 700 side around the tip 111A of the projection 111 (step ST3). Also, as shown in Figures 16 and 17, the lance 112 contacts the projection 302A of the lance receiving portion 302 and undergoes compressive deformation in the pitch direction. Further rotation of the shell 110 causes the lance 112 to pass beyond the projection 302A and be received within the recess 302B. The compressive deformation of the lance 112 is released, and the lance 112 expands in the pitch direction. The width of the two lances 112 in the pitch direction may return to their original size.

[0038] As described above, the connector 100 can be attached to the substrate 700 via the frame 300, as shown in Figures 1 to 8. As shown in Figures 6 to 8, multiple contacts 121A and 121B press against and make contact with multiple pads 702, thereby making an electrical connection. As described above, by installing the frame 300 on the substrate 700, the position of the frame 300 relative to the substrate 700 can be determined with high precision. Therefore, each contact 121A and 121B and each pad 702 can be precisely positioned and reliably electrically connected. Furthermore, since the multiple contacts 121A and 121B are compressed in the vertical direction, the projection 111 and lance 112 receive reaction forces from the multiple contacts 121A and 121B via the insulator 130 and shell 110. The projection 111 contacts the projection receiving portion 301. The lance 112 also contacts the lance receiving portion 302.

[0039] The user grasps the mating opening 110A of the connector 100 or its vicinity and attaches the connector 100 to the substrate 700 via the frame 300. Here, the projection 111 is the fulcrum, the multiple contacts 121A and 121B are the points of application, and the mating opening 110A or its vicinity is the point of force application. Due to the lever principle, by applying a predetermined force to the mating opening 110A or its vicinity, a force greater than that predetermined force can be applied to the multiple contacts 121A and 121B. Therefore, the user can attach the connector 100 to the substrate 700 via the frame 300 by applying a small force to the mating opening 110A or its vicinity.

[0040] To remove the connector 100 from the circuit board 700, as shown in Figures 18 and 19, first insert a flathead screwdriver 800 into the groove 302C of the lance receiving portion 302. The tip 801 of the flathead screwdriver 800 will come into contact with the lance 112, compressing and deforming the lance 112 in the pitch direction. A widely available flathead screwdriver 800 can be used. Two flathead screwdrivers 800 may be inserted simultaneously into the two lance receiving portions 302. After that, each step should be performed in the reverse order of the method for attaching the connector 100 to the circuit board 700 described above. That is, while keeping the projection 111 in contact with the projection receiving portion 301, rotate the shell 110 around the tip 111A of the projection 111 in a direction away from the circuit board 700. Next, while keeping the orientation of the connector 100 tilted, move the connector 100 in a direction away from the frame 300. This allows the connector 100 to be removed from the circuit board 700. If the frame 300 remains attached to the circuit board 700, the connector 100 can be reattached to the circuit board 700 via the frame 300.

[0041] The method of attaching the connector 100 to the circuit board 700 via the frame 300 and the method of removing the connector 100 from the circuit board 700 described above 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 hands. Therefore, the connector 100 can be easily attached to and removed from the circuit board 700 via the frame 300.

[0042] <Second Embodiment> Next, a second embodiment of the present disclosure will be described with reference to Figures 20 to 32.

[0043] As shown in Figures 20 to 26, the connector assembly 600 comprises a connector 200 and a frame 400.

[0044] Connector 200 has the same configuration as connector 100, except that it includes a slider 210.

[0045] As shown in Figure 26, the slider 210 is attached to the shell 110 so as to be slidable relative to the shell 110 in the fitting direction (here, the X-axis direction). The slider 210 comprises a slider body 211 and a wing 212. The slider body 211 may be a substantially cylindrical body that encloses the shell 110. The slider body 211 has a fitting opening 211A and a substrate-side opening 211B. The wing 212 is a plate-like portion that protrudes outward in the pitch direction (here, the Y-axis direction) from the slider body 211. The wing 212 extends in the fitting direction. In the second embodiment, the slider body 211 can be slit to form the wing 212 and a hole 213. The slider body 211 has a hole 214. When the slider 210 is attached to the shell 110, the wing 212 should be located on the side 110F and 110G of the slider body 211. The hole 214 should be located on the top surface 110D of the slider body 211.

[0046] The shell 110 may be provided with protrusions 113, 114, and 115. The two protrusions 113 may be provided on the sides 110F and 110G, respectively. The two protrusions 113 protrude outward in the pitch direction from the sides 110F and 110G, respectively. The protrusions 114 and 115 protrude upward from the top surface 110D. The protrusion 114 is positioned at a predetermined distance from the protrusion 115 towards the fitting opening 211A. The protrusion 114 has a shape that allows it to be inserted into the hole 214 of the slider body 211. The protrusion 114 has a slope.

[0047] Frame 400 has the same configuration as frame 300, except that it has grooves 402. The two grooves 402 are provided on the sides 303B and 303C of the frame body 303 of frame 400. The two grooves 402 are preferably provided on the sides 303B and 303C so as to face each other. The grooves 402 extend in the fitting direction (in this case, the X-axis direction). The grooves 402 are preferably shaped so that the wing 212 can be inserted into them.

[0048] <Method> Next, we will describe how to attach the connector 200 to the circuit board 700 via the frame 400.

[0049] Prior to this method, the frame 400 is pre-installed on the substrate 700. Specifically, as shown in Figures 25 and 27, bolts 310 are inserted through holes 304 in the frame 400 and holes 703 in the substrate 700 and fastened with nuts 320. Positioning protrusions 305A and 305B of the frame 400 are inserted into positioning holes 705A and 705B, respectively. This allows for accurate positioning of the frame 400 relative to the substrate 700. In addition, the slider 210 is pre-moved from the substrate-side opening 110B of the shell 110 to the fitting opening 110A. It is preferable to move the slider 210 until the protrusion 114 is positioned on the substrate-side end 110C side (in this case, the negative X-axis direction) of the slider body 211 beyond the substrate-side opening 211B. Furthermore, if the mating between connector 200 and the mating connector is released, moving the slider 210 further toward the mating connector (in this case, in the positive X-axis direction) will cause the protrusion 113 to interfere with the substrate-side opening 211B, suppressing further movement of the slider 210 and preventing it from detaching from the shell 110. In other words, the slider 210 remains attached to the shell 110. At this time, the protrusion 114 is located toward the substrate-side end 110C (in this case, in the negative X-axis direction) from the substrate-side opening 211B. Because the protrusion 114 has a slope, when the slider 210 is pushed toward the mating connector (in this case, in the positive X-axis direction), the substrate-side opening 211B will move over the protrusion 114, but further movement of the slider 210 is not easy. The slider 210 can maintain its state of being attached to the shell 110. In other words, simply pushing the slider 210 toward the mating connector with normal force will move the slider 210 to the appropriate position.

[0050] As shown in Figure 27, the orientation of the connector 200 is tilted (step ST21), similar to step ST1 described above. Specifically, the orientation of the connector 100 is tilted so that the projection 111 is closer to the mounting surface 701 of the substrate 700.

[0051] Next, as shown in Figures 28 to 31, the connector 200 is moved toward the frame 400 while keeping the orientation of the connector 200 tilted, similar to step ST2 described above (step ST22). Furthermore, as shown in Figure 31, the projection 111 is inserted into the projection receiving portion 301.

[0052] Next, while the projection 111 is in contact with the projection receiving portion 301, the shell 110 is rotated toward the substrate 700 side around the tip 111A of the projection 111 (step ST23). As shown in Figure 32, the wing 212 is positioned near the groove 402.

[0053] Finally, as shown in Figures 20 to 24, the wing 212 is inserted into the groove 402 (step ST24). Specifically, the slider 210 is slid toward the central part 303A of the frame body 303. Then, the protrusion 114 fits into the hole 214 of the slider body 211. This generates vibration and sound that are transmitted to the user, giving the user a click sensation. Therefore, the user can slide the slider 210 while feeling the click sensation. If the slider 210 is slid further, the substrate-side opening 211B of the slider body 211 will come into contact with the protrusion 115. This restricts the sliding of the slider 210. It also prevents the wing 212 from colliding with the groove 402 and being damaged.

[0054] As described above, the connector 200 can be attached to the substrate 700 via the frame 400. As shown in Figure 23, multiple contacts 121A and 121B press against and make contact with multiple pads 702, thereby making an electrical connection. As described above, by installing the frame 400 on the substrate 700, the position of the frame 400 relative to the substrate 700 is precisely determined. Therefore, each contact 121A and 121B and each pad 702 can be precisely positioned and reliably electrically connected. In addition, since the multiple contacts 121A and 121B are compressed in the vertical direction, the projection 111 and wing 212 receive reaction forces from the multiple contacts 121A and 121B via the insulator 130 and shell 110. As shown in Figure 24, the projection 111 contacts the projection receiving portion 301. As shown in Figures 20 and 22, the wing 212 contacts the groove 402.

[0055] To remove the connector 200 from the circuit board 700, simply perform the steps in the reverse order of the method for attaching the connector 200 to the circuit board 700 described above. That is, remove the wing 212 from the groove 402. Next, while keeping the projection 111 in contact with the projection receiving portion 301, rotate the shell 110 around the tip 111A of the projection 111 in a direction away from the circuit board 700. Finally, while keeping the orientation of the connector 200 tilted, move the connector 200 in a direction away from the frame 400. This will allow you to remove the connector 200 from the circuit board 700. If the frame 400 is left installed on the circuit board 700, the connector 200 can be reattached to the circuit board 700 via the frame 400.

[0056] The method of attaching the connector 200 to the circuit board 700 via the frame 400 and the method of removing the connector 200 from the circuit board 700 described above 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 700 via the frame 400.

[0057] 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 700 having a concave surface 704A 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.
