[Modes for carrying out the invention]

[0008] On the other hand, there is a demand to adjust the impedance of the connector to a higher value in order to match the desired value. Generally, impedance tends to decrease in smaller connectors. In such miniaturized connectors, it has not been easy to increase the impedance while maintaining robustness and reliability.

[0009] According to a connector module and electronic device according to one embodiment of the present disclosure, it is possible to increase the impedance even in a miniaturized connector.

[0010] Hereinafter, an embodiment of this disclosure will be described in detail with reference to the attached drawings. In the following description, the directions of front / back, left / right, and up / down are based on the directions of the arrows in the figures. The directions of each arrow are consistent across different drawings in Figures 1 to 5 and Figures 8 to 11. The directions of each arrow are also consistent across different drawings in Figures 6 and 7. In some drawings, for the purpose of simplified illustration, the circuit boards CB1 and CB2, which will be described later, are omitted.

[0011] Figure 1 is a top-view perspective view of a connector module 1 according to one embodiment, showing the state in which the first connector 50 and the second connector 10 are connected to each other. Figure 2 is a top-view perspective view of a connector module 1 according to one embodiment, showing the state in which the first connector 50 and the second connector 10 are separated from each other.

[0012] For example, as shown in FIG. 2, the connector module 1 has a first connector 50 and a second connector 10 that can be fitted to each other. The second connector 10 is connected to the connection object with the first connector 50 as the connection object. The second connector 10 has a second insulator 20 and a second contact 30 attached to the second insulator 20. The second connector 10 has a second fitting 40a and a third fitting 40b attached to the second insulator 20.

[0013] The first connector 50 fits with the second connector 10. The first connector 50 has a first insulator 60 that fits with the second insulator 20 in a fitting state where the first connector 50 and the second connector 10 fit with each other. The first connector 50 has a first contact 70 attached to the first insulator 60. The first contact 70 contacts the second contact 30 in a fitting state where the first insulator 60 and the second insulator 20 fit with each other. The first connector 50 has a first fitting 80 attached to the first insulator 60. The first fitting 80 contacts the second fitting 40a in the fitting state. At this time, the second fitting 40a elastically deformes.

[0014] Hereinafter, for example, the second connector 10 according to an embodiment will be described as a receptacle connector. For example, the first connector 50 will be described as a plug connector. In a fitting state where the second insulator 20 and the first insulator 60 fit with each other, the second connector 10 in which the second contact 30 elastically deformes will be described as a receptacle connector. In the fitting state, the first connector 50 in which the first contact 70 does not elastically deform will be described as a plug connector. The types of the second connector 10 and the first connector 50 are not limited to these. For example, the second connector 10 may play the role of a plug connector, and the first connector 50 may play the role of a receptacle connector.

[0015] Hereinafter, the first connector 50 and the second connector 10 will be described as being respectively mounted on the circuit boards CB1 and CB2. The first connector 50 and the second connector 10 electrically connect the circuit board CB1 and the circuit board CB2 in a connected state where they are connected to each other. The circuit boards CB1 and CB2 may be rigid boards, or any other circuit boards. For example, at least one of the circuit boards CB1 and CB2 may be a flexible printed circuit board (FPC).

[0016] Hereinafter, the first connector 50 and the second connector 10 will be described as being connected to each other in a direction perpendicular to the circuit boards CB1 and CB2. As an example, the first connector 50 and the second connector 10 are connected to each other along the vertical direction. The connection method is not limited to this. The first connector 50 and the second connector 10 may be connected to each other in a direction parallel to the circuit boards CB1 and CB2. The first connector 50 and the second connector 10 may be connected to each other such that one is in the vertical direction with respect to the mounted circuit board and the other is in the parallel direction with respect to the mounted circuit board.

[0017] In the present disclosure, the "fitting direction" corresponds to the vertical direction as an example. The "longitudinal direction" corresponds to the left - right direction as an example. The "arrangement direction" corresponds to the left - right direction as an example. The "short - side direction" corresponds to the front - rear direction as an example. The "fitting side" corresponds to the lower side as an example. The "removal side" corresponds to the upper side as an example. The "circuit board CB2 side" corresponds to the lower side as an example. The "side opposite to the circuit board CB2" corresponds to the upper side as an example. The "inside" corresponds to the direction toward the center of the first connector 50 or the second connector 10. For example, the inside in the front - rear direction corresponds to the direction toward the center of the first connector 50 or the second connector 10 in the front - rear direction. It is not limited to this, and the inside may not be exactly in the direction toward the center in the front - rear direction, and may correspond to the direction toward the center along a somewhat diagonal direction. The same applies to other directions. The "outside" is the reverse of the inside.

[0018] Figure 3 is an external perspective view of the second connector 10 shown in Figure 1, viewed from above. The second connector 10 is obtained, for example, by integrally molding the third metal fitting 40b and the second insulator 20 by insert molding, and then press-fitting the second contact 30 and the second metal fitting 40a into the second insulator 20.

[0019] Figure 4 is an external perspective view of the second connector 10 of Figure 3, disassembled and viewed from above. In reality, the third metal fitting 40b and the second insulator 20 are integrally molded by insert molding, but in Figure 4, for ease of understanding, the second insulator 20 and the third metal fitting 40b are virtually separated and shown as individual components. Accordingly, for convenience, the third metal fitting holding portion 25 of the second insulator 20, which will be described later, is given this name, but please note that in reality, the third metal fitting 40b and the second insulator 20 are integrally molded by insert molding, and these components are not inherent to the second insulator 20 as part of its original structure.

[0020] The second insulator 20, which constitutes the second connector 10, is made of an insulating and heat-resistant synthetic resin material. The second insulator 20 extends in a plate shape in the left-right direction. The second insulator 20 has a bottom plate portion 21 that constitutes the lower part. The second insulator 20 has a mating projection 22 that protrudes upward from the center of the front, back, left, and right sides of the bottom plate portion 21. The second insulator 20 has an outer peripheral wall 23 that surrounds the mating projection 22. The outer peripheral wall 23 is located on the outer periphery of the second connector 10. The outer peripheral wall 23 surrounds the mating projection 22 from four directions: front, back, left, and right. The outer peripheral wall 23 has a short wall 23a and a long wall 23b. The short wall 23a extends in the front-back direction. The long wall 23b extends in the left-right direction.

[0021] The second insulator 20 has a second contact mounting groove 24 that is arranged across the front-to-back inner surface of the longitudinal wall 23b, the bottom plate portion 21, and the front-to-back inner surface of the fitting projection 22. The second contact 30 is mounted in the second contact mounting groove 24. Multiple second contact mounting grooves 24 are arranged corresponding to the number of second contacts 30. The multiple second contact mounting grooves 24 are arranged along the arrangement direction of the multiple second contacts 30.

[0022] The second insulator 20 has a third fitting holder 25 that extends from the left-right ends of the fitting projection 22 through the bottom plate 21 to the short wall 23a. The third fitting holder 25 has a first portion 251 that is recessed at the left-right ends of the fitting projection 22. The third fitting holder 25 has a second portion 252 that is positioned to penetrate the bottom plate 21. The third fitting holder 25 has a third portion 253 that is recessed on the lower surface of the short wall 23a. The third fitting 40b is attached to the third fitting holder 25. The third fitting holder 25 extends along the left-right direction to connect the fitting projection 22 and the short wall 23a.

[0023] The second insulator 20 has a second fitting mounting portion 26 that is positioned across the left and right ends of the longitudinal wall 23b and the short wall 23a. The second fitting 40a is attached to the second fitting mounting portion 26.

[0024] The second fitting mounting portion 26 is located in the center of the front-to-back direction of the short wall 23a and has a first wall portion 261 that protrudes outward in the left-to-right direction. The third portion 253 of the third fitting holding portion 25 is recessed in the lower surface of the first wall portion 261. The second fitting mounting portion 26 has a second wall portion 262 located on the short wall 23a at the corner of the second insulator 20. The second fitting mounting portion 26 has a third wall portion 263 located on the long wall 23b, spaced apart from the second wall portion 262 in the left-to-right direction. The first wall portion 261, the second wall portion 262, and the third wall portion 263 form the outermost rectangular shape of the second insulator 20 in the front-to-back and left-to-right directions.

[0025] The second fitting mounting portion 26 has a first mounting groove 264 located between the first wall portion 261 and the second wall portion 262. The second fitting mounting portion 26 has a second mounting groove 265 located between the second wall portion 262 and the third wall portion 263.

[0026] The second fitting mounting portion 26 has a fourth wall portion 266 that extends linearly in the left-right direction between the third wall portion 263 and the short wall 23a, and whose height in the vertical direction is one level lower than the other parts of the long wall 23b. The second fitting mounting portion 26 has a contacted portion 267 that is continuously arranged on the inside of the outer peripheral wall 23 in the fourth wall portion 266.

[0027] The contacted portion 267 is located on the mating side of the first connector 50 relative to the second connector 10, and is positioned further inward from the outer peripheral wall 23. For example, the contacted portion 267 has an inclined surface 267a that slopes inward in the front-rear direction of the outer peripheral wall 23 as it approaches the mating side in the fourth wall portion 266, i.e., the longitudinal wall 23b. The contacted portion 267, including the inclined surface 267a, extends in the left-right direction along substantially the entire fourth wall portion 266 from the short wall 23a to the third wall portion 263.

[0028] The second insulator 20 has protrusions 27 positioned between the second contact mounting grooves 24 in the bottom plate portion 21. The protrusions 27 have a thickness greater than the vertical thickness of the portions located at both ends in the left-right direction of the bottom plate portion 21. Multiple protrusions 27 are arranged corresponding to the number of second contact mounting grooves 24. The multiple protrusions 27 are arranged along the arrangement direction of the multiple second contacts 30. In the bottom plate portion 21, the second contact mounting grooves 24 and the protrusions 27 are arranged alternately along the left-right direction.

[0029] Figure 5 is a cross-sectional view along the VV arrow in Figure 3. The configuration of the second contact 30 will be mainly explained with reference to Figures 4 and 5.

[0030] The second contact 30 is formed from a thin sheet of a copper alloy containing, for example, phosphor bronze, beryllium copper, or titanium copper, or a Corson-type copper alloy, which has spring elasticity, using a progressive die (stamping) to form the shape shown in Figures 4 and 5. The surface of the second contact 30 is plated with nickel after an undercoat has been applied, followed by plating with gold or tin.

[0031] The second contact 30 has a mounting portion 31 that extends outward in an L-shape in the front-rear direction. The second contact 30 has a locking portion 32 that extends upward from the upper end of the mounting portion 31. The locking portion 32 is wider in the left-right direction than the mounting portion 31. The second contact 30 has a curved portion 33 that protrudes upward in a U-shape from the locking portion 32.

[0032] The second contact 30 has an elastic contact piece 34 that is continuous with the curved portion 33 and arranged in an S-shape. The second contact 30 has an extension 34a located below the elastic contact piece 34 that extends linearly in the front-rear direction from the lower end of the curved portion 33. The second contact 30 has an elastic contact portion 35 that is positioned outward in the front-rear direction at the bent portion at the tip of the elastic contact piece 34. The second contact 30 has a free end 36 located on the opposite side of the mounting portion 31. The free end 36 is located in the front-rear direction at the end of the elastic contact piece 34 opposite to the portion that is continuous with the curved portion 33.

[0033] The configuration of the second fitting 40a will be mainly explained, with reference primarily to Figure 4.

[0034] The second fitting 40a is formed from a thin sheet of any metal material using a progressive die (stamping) to the shape shown in Figure 4. The processing method for the second fitting 40a includes a step of bending the sheet in the thickness direction after punching. However, it is not limited to this, and the second fitting 40a may also be processed by a process that includes deep drawing.

[0035] The second fitting 40a has a first base portion 41a extending in the front-rear direction. The second fitting 40a has a second base portion 42a extending from each of the front-rear ends of the first base portion 41a to one side in the left-right direction. The second fitting 40a has protruding pieces 43a extending linearly downward from the front and rear ends of the first base portion 41a. A recess is formed by the opposing edges of a pair of protruding pieces 43a spaced apart from each other in the front-rear direction and the left-right end edges of the first base portion 41a. The second fitting 40a has a first mounting portion 44a located at the lower end of the protruding piece 43a. The second fitting 40a has a first locking portion 45a that is wider in the front-rear direction than other parts of the protruding piece 43a.

[0036] The second fitting 40a has a bent portion 46a that bends from the center in the front-rear direction to the left-right direction at one end edge in the left-right direction of the first base portion 41a. The second fitting 40a has a first engaging portion 46a1 located on the left-right surface of the bent portion 46a facing one side in the left-right direction. The first engaging portion 46a1 has a convex portion that protrudes to the left-right direction on the surface of the bent portion 46a. The second fitting 40a has a second engaging portion 46a2 located directly below the first engaging portion 46a1 on the surface of the bent portion 46a. The second engaging portion 46a2 has a concave portion that recesses to the other side in the left-right direction on the surface of the bent portion 46a.

[0037] The second fitting 40a has a second locking portion 47a that extends downward from the outer edge in the front-rear direction of the second base portion 42a over substantially the entire length in the left-right direction. The second locking portion 47a has a portion that is wider in the left-right direction than the second base portion 42a. The second fitting 40a has a second mounting portion 48a that extends over substantially the entire length in the left-right direction at the lower end of the second locking portion 47a.

[0038] The second fitting 40a has an extension portion 49a that extends inward from the edge of the second base 42a opposite to the second locking portion 47a. The extension portion 49a extends from one end in the left-right direction at the inner edge of the second base 42a in the front-rear direction, bending diagonally downward. The extension portion 49a extends to a position corresponding to the center of the second locking portion 47a in the vertical direction. The extension portion 49a is inclined inward in the front-rear direction from top to bottom. The extension portion 49a is elastically deformable towards the second locking portion 47a along the front-rear direction when contact pressure is applied, starting from a free state where no contact pressure is applied due to contact with the first connector 50. The extension portion 49a has spring elasticity.

[0039] The second fitting 40a has a first engaging portion 49a1 located on the front-rear surface of the extension portion 49a facing away from the second locking portion 47a. The first engaging portion 49a1 has a protrusion on the surface of the extension portion 49a that projects away from the second locking portion 47a. The second fitting 40a has a second engaging portion 49a2 located on the surface of the extension portion 49a directly below the first engaging portion 49a1. The second engaging portion 49a2 has a recess on the surface of the extension portion 49a that is recessed toward the second locking portion 47a.

[0040] The configuration of the third fitting 40b will be mainly explained, with reference primarily to Figure 4.

[0041] The third fitting 40b is formed from a thin sheet of any metal material using a progressive die (stamping) to the shape shown in Figure 4. The processing method for the third fitting 40b includes processes based on punching and bending in the thickness direction of the sheet. However, it is not limited to this, and the third fitting 40b may also be processed by a process including drawing so that the front, rear, left, right, and top surfaces of the first base 41b, as described later, are continuous without gaps.

[0042] The third fitting 40b is arranged so that its overall shape is crank-shaped. More specifically, the first base portion 41b and the second base portion 42b, which will be described later, are integrally arranged so that the whole is crank-shaped.

[0043] The third fitting 40b has a first base 41b. The first base 41b extends linearly from below upward and bends at its upper end toward one side in the left-right direction. The first base 41b is arranged in an L-shape. The third fitting 40b has a second base 42b that extends linearly from the lower end of the first base 41b toward the other side in the left-right direction. The front-rear width of the second base 42b is the same as the front-rear width of the first base 41b which is continuous with the second base 42b.

[0044] The third fitting 40b has a wide portion 43b that extends in a bifurcated manner to the other side in the left-right direction from the other end of the second base portion 42b so as to widen in the front-rear direction. The third fitting 40b has a mounting portion 44b that extends linearly to the other side in the left-right direction from the front-rear center of the bifurcated wide portion 43b. The mounting portion 44b bends diagonally downward from the wide portion 43b and then extends linearly to the other side in the left-right direction. The mounting portion 44b is located one level below the second base portion 42b and the wide portion 43b.

[0045] As shown in Figure 5, the second contact 30 is press-fitted into the second insulator 20 from below. At this time, the locking portion 32 engages with the inner wall surface of the second contact mounting groove 24 in the left-right direction. This holds the second contact 30 in place with respect to the second contact mounting groove 24. The second contact 30 is attached to the longitudinal wall 23b.

[0046] When the second contact 30 is held in the second contact mounting groove 24 of the second insulator 20, the elastic contact portion 35 is exposed from the second contact mounting groove 24 between the fitting projection 22 and the longitudinal wall 23b. At this time, the elastic contact piece 34 is elastically deformable in the front-rear direction within the second contact mounting groove 24. The free end 36 is positioned so that the upper end of the fitting projection 22 overlaps directly above it. The front-rear tip of the mounting portion 31 is at approximately the same front-rear position as the longitudinal wall 23b.

[0047] As shown in Figure 4, the second fitting 40a and the third fitting 40b are different components. The second fitting 40a and the third fitting 40b are separate from each other. The second fitting 40a and the third fitting 40b face each other in the left-right direction while separated from each other. The strengths of the second fitting 40a and the third fitting 40b are different. The strength of one of the second fitting 40a and the third fitting 40b is higher than the strength of the other. For example, the strength of the third fitting 40b may be higher than the strength of the second fitting 40a. For example, the strength of the material of the third fitting 40b may be higher than the strength of the material of the second fitting 40a. In this specification, "strength" includes, for example, tensile strength.

[0048] The material of the third fitting 40b may be different from the material of the second fitting 40a. For example, the material of the third fitting 40b may be stainless steel and the material of the second fitting 40a may be phosphor bronze. However, the materials of the second fitting 40a and the third fitting 40b may be selected from a group of candidate materials in any combination such that the strength of the third fitting 40b is greater than the strength of the second fitting 40a. In this specification, the "group of candidate materials" includes, for example, stainless steel, phosphor bronze, iron, Corson copper, titanium copper, beryllium copper, and aluminum.

[0049] The material of the third fitting 40b may be the same as that of the second fitting 40a, as long as the strength of the third fitting 40b is higher than that of the second fitting 40a. For example, even if the material of the third fitting 40b is the same, such as phosphor bronze, the strength of the third fitting 40b may be higher than that of the second fitting 40a if the alloy number, type symbol, and temper are different. For example, even if the material of the third fitting 40b is the same, such as phosphor bronze, the strength of the third fitting 40b may be higher than that of the second fitting 40a if the plate thickness of the third fitting 40b is greater than that of the second fitting 40a, as will be described later.

[0050] For example, the strength of the second contact 30 may be approximately the same as the strength of the second fitting 40a. The strength of the third fitting 40b may be higher than that of the second contact 30 in addition to that of the second fitting 40a. The materials for the second fitting 40a, the third fitting 40b, and the second contact 30 may be selected from a group of candidate materials in any combination that satisfies the above-described strength relationship between the second fitting 40a, the third fitting 40b, and the second contact 30.

[0051] A pair of third fittings 40b are attached to both ends of the mating projection 22 in the longitudinal direction of the second connector 10. The third fittings 40b extend along the longitudinal direction of the second connector 10 from the mating projection 22 to the short wall 23a to which the second fitting 40a is attached.

[0052] For example, the third fitting 40b is integrally molded with the third fitting holding portion 25 of the second insulator 20 by insert molding. In this case, the first base portion 41b is integrally molded with the fitting projection 22 from its upper surface to its side surface at the left-right ends of the fitting projection 22. For example, the first base portion 41b is integrally molded with the first portion 251 of the third fitting holding portion 25. The first base portion 41b covers the entire left-right end of the fitting projection 22 from the outside.

[0053] The second base portion 42b is integrally molded with the bottom plate portion 21. The second base portion 42b is integrally molded with a part of the second portion 252 of the third fitting holder portion 25. The wide portion 43b is integrally molded with the remaining part of the second portion 252 of the third fitting holder portion 25. The mounting portion 44b is integrally molded with the third portion 253 of the third fitting holder portion 25. In this state, the left-right leading edge of the mounting portion 44b is exposed outward in the left-right direction from the first wall portion 261 of the short wall 23a.

[0054] When the third fitting 40b and the second insulator 20 are integrally molded by insert molding, the second base portion 42b and the wide portion 43b extend along the longitudinal direction of the second connector 10. The second base portion 42b and the wide portion 43b extend from the mating projection 22 to the short wall 23a to which the second fitting 40a is attached. The lower surface of the mounting portion 44b is located one level below the bottom surface of the bottom plate portion 21 of the second insulator 20. In the left-right direction, the mounting portion 44b is located directly below the short wall 23a.

[0055] The second fitting 40a is press-fitted from above the second insulator 20. The second fitting 40a is attached to the outer peripheral wall 23 such that a recess, formed by the opposing edges of a pair of projecting pieces 43a spaced apart from each other in the front-rear direction and the left-right edge of the first base 41a, sandwiches the first wall 261.

[0056] At this time, the first locking portion 45a locks onto the first wall portion 261 of the second fitting mounting portion 26 on the outside of the short wall 23a in the left-right direction. The pair of protruding pieces 43a, which are spaced apart from each other in the front-rear direction, are attached to the first mounting groove 264. Similarly, the second locking portion 47a locks onto the second wall portion 262 and the third wall portion 263 of the second fitting mounting portion 26 on the outside of the long wall 23b in the front-rear direction. The second locking portion 47a is attached to the second mounting groove 265. As a result, the second fitting 40a is held in place by the second fitting mounting portion 26.

[0057] The first base 41a and the second base 42a of the second fitting 40a are arranged along the outer perimeter wall 23. More specifically, the first base 41a is arranged along the short side wall 23a. The second base 42a is arranged along the long side wall 23b. The extension 49a extends from the second base 42a inward from the outer perimeter wall 23. The extension 49a is located on the long side wall 23b.

[0058] The protrusions included in the first engaging portion 49a1 of the extension portion 49a project from the surface of the extension portion 49a toward the side opposite to the outer peripheral wall 23. In a pair of extension portions 49a arranged in the front-rear direction, the protrusions of the pair of first engaging portions 49a1 face each other in the front-rear direction via the left-right ends of the fitting protrusions 22. The pair of first engaging portions 49a1 are arranged in the same left-right and up-down positions on the second fitting 40a.

[0059] The recesses included in the second engaging portion 49a2 of the extension portion 49a are positioned toward the outer peripheral wall 23 from the surface of the extension portion 49a. In a pair of extension portions 49a arranged in the front-rear direction, the recesses of the pair of second engaging portions 49a2 face each other in the front-rear direction via the left-right ends of the fitting projection portion 22. The pair of second engaging portions 49a2 are positioned at the same left-right and up-down positions on the second fitting 40a.

[0060] When the second fitting 40a is held by the second fitting mounting portion 26 of the second insulator 20, it covers the entire short wall 23a and the left-right ends of the long wall 23b. At this time, the second fitting 40a surrounds the first base portion 41b, the second base portion 42b, and the wide portion 43b of the third fitting 40b from both the front and rear sides and the left and right sides. More specifically, the second base portion 42a of the second fitting 40a is positioned on both the front and rear sides relative to the first base portion 41b, the second base portion 42b, and the wide portion 43b of the third fitting 40b. The first base portion 41a, the protruding piece 43a, and the bent portion 46a of the second fitting 40a are positioned to overlap in the left-right direction with the left-right outer end and the mounting portion 44b of the wide portion 43b of the third fitting 40b.

[0061] The first mounting portion 44a is positioned along the left-right outer surface of the short wall 23a. The first mounting portion 44a extends downward from the lower end of the short wall 23a. The first mounting portion 44a is positioned on both sides of the mounting portion 44b of the third fitting 40b in the short direction of the second connector 10. The pair of first mounting portions 44a are positioned so as to sandwich the mounting portion 44b of the third fitting 40b from both sides in the front-rear direction. For example, the pair of first mounting portions 44a are positioned symmetrically in the front-rear direction with respect to the mounting portion 44b of the third fitting 40b.

[0062] The second mounting portion 48a is positioned along the outer surface of the longitudinal wall 23b in the front-rear direction. The second mounting portion 48a extends downward from the lower end of the longitudinal wall 23b. The second mounting portion 48a is positioned on both sides of the third fitting 40b in the short direction of the second connector 10. The pair of second mounting portions 48a are positioned so as to sandwich the first base portion 41b, the second base portion 42b, and the wide portion 43b of the third fitting 40b from both sides in the front-rear direction. For example, the pair of second mounting portions 48a are positioned symmetrically in the front-rear direction with respect to the first base portion 41b, the second base portion 42b, and the wide portion 43b.

[0063] In the second connector 10 having the structure described above, the mounting portion 31 of the second contact 30 is soldered to the circuit pattern placed on the mounting surface of the circuit board CB2. The first mounting portion 44a and the second mounting portion 48a of the second metal fitting 40a and the mounting portion 44b of the third metal fitting 40b are soldered to the pattern placed on the said mounting surface. As a result of mounting each mounting portion onto the circuit board CB2, the second connector 10 is mounted on the circuit board CB2. Other electronic components, such as a CPU (Central Processing Unit), controller, and memory, are mounted on the mounting surface of the circuit board CB2, separate from the second connector 10.

[0064] The configuration of the first connector 50 will be explained primarily with reference to Figures 6 and 7.

[0065] Figure 6 is an external perspective view of the first connector 50 shown in Figure 1, viewed from above. The first connector 50 is obtained, for example, by integrally molding the first contact 70 and the first insulator 60 by insert molding, and then press-fitting the first metal fitting 80 into the first insulator 60 from above.

[0066] Figure 7 is an external perspective view of the first connector 50 of Figure 6, disassembled and viewed from above. In reality, the first contact 70 and the first insulator 60 are integrally molded by insert molding, but in Figure 7, for ease of understanding, the first insulator 60 and the first contact 70 are virtually separated and shown as individual components. Accordingly, for convenience, components such as the first contact holding portion 64 of the first insulator 60, which will be described later, are given this name, but please note that in reality, the first contact 70 and the first insulator 60 are integrally molded by insert molding, and these components are not inherent to the first insulator 60's original configuration.

[0067] The first insulator 60 is a plate-shaped member extending in the left-right direction, injection-molded from an insulating and heat-resistant synthetic resin material. The first insulator 60 has a bottom plate portion 61 that forms the lower part. The first insulator 60 has an annular outer peripheral wall 62 that protrudes upward along the front, rear, left, and right outer circumference of the bottom plate portion 61. The outer peripheral wall 62 has a short wall 62a and a long wall 62b. The short wall 62a extends in the front-rear direction. The long wall 62b extends in the left-right direction. The first insulator 60 has a fitting recess 63 surrounded from the front, rear, left, and right by the outer peripheral wall 62.

[0068] The first insulator 60 has a first contact holder 64 that is arranged across the longitudinal wall 62b and the bottom plate portion 61. The first contact 70 is attached to the first contact holder 64. Multiple first contact holders 64 are arranged in a manner corresponding to the number of first contacts 70. The multiple first contact holders 64 are arranged along the direction of arrangement of the multiple first contacts 70.

[0069] The first insulator 60 has a first fitting mounting portion 65 that extends from the left-right end of the long wall 62b to the short wall 62a. The first fitting 80 is attached to the first fitting mounting portion 65.

[0070] The first fitting mounting portion 65 has a first wall portion 651 located on the short wall 62a at the corner of the first insulator 60. The first fitting mounting portion 65 has a second wall portion 652 located on the long wall 62b, spaced apart from the first wall portion 651 in the left-right direction. The first wall portion 651 and the second wall portion 652 form the outermost rectangular shape of the first insulator 60 in the front-back and left-right directions. The upper surface of the portion of the first fitting mounting portion 65 that extends linearly in the left-right direction between the first wall portion 651 and the second wall portion 652 is at the same height as the upper surface of the first contact 70 held by the first insulator 60.

[0071] The first fitting mounting portion 65 has a first mounting groove 653 located between a pair of first wall portions 651. The first fitting mounting portion 65 has a second mounting groove 654 located between the first wall portion 651 and the second wall portion 652.

[0072] The first insulator 60 has an outer wall 66 that extends laterally along the longitudinal wall 62b to connect a pair of second wall portions 652 located on both sides in the left-right direction. The outer wall 66 extends parallel to the longitudinal wall 62b along the arrangement direction of the plurality of first contact holding portions 64, over the entire arrangement region of the plurality of first contact holding portions 64. The outer wall 66 is located on the outside in the front-rear direction relative to the longitudinal wall 62b and covers a portion of the first contact holding portions 64 from the outside in the front-rear direction.

[0073] This section will primarily describe the configuration of the first contact, 70.

[0074] The first contact 70 is formed from a thin sheet of copper alloy containing, for example, phosphor bronze, beryllium copper, or titanium copper, or a Corson-type copper alloy, using a progressive die (stamping) to form the shape shown in Figure 7. The surface of the first contact 70 is plated with nickel first, followed by plating with gold or tin.

[0075] The first contact 70 has a mounting portion 71 that extends outward in an L-shape in the front-rear direction. The first contact 70 has an extension portion 72 connected to the mounting portion 71. The extension portion 72 extends linearly upward from the upper end of the mounting portion 71 with approximately the same left-right width as the mounting portion 71. The first contact 70 has a folded portion 73 that folds back upward in an inverted J-shape from the upper end of the extension portion 72. In the arrangement direction of the multiple first contacts 70, the width of the extension portion 72 is smaller than the width of the folded portion 73. The left-right width of the extension portion 72 is smaller than the left-right width of the folded portion 73.

[0076] The first contact 70 has a contact portion 74 located on the folded portion 73. The contact portion 74 is configured to include an inner surface facing the front-to-back center of the first connector 50 in the folded portion 73. The first contact 70 has a free end 75 located on the opposite side of the mounting portion 71. The free end 75 is located directly below the contact portion 74 in the folded portion 73. The free end 75 is connected to the extension portion 72 via the folded portion 73. The folded portion 73 connects the extension portion 72 and the free end 75.

[0077] This section will primarily describe the configuration of the first fitting 80.

[0078] The first fitting 80 is formed from a thin sheet of any metal material into the shape shown in Figure 7 using a progressive die (stamping). The processing method for the first fitting 80 includes a step of bending the sheet in the thickness direction after punching.

[0079] The first fitting 80 has a first base portion 81 that extends in the front-rear direction. The first fitting 80 has a second base portion 82 that extends from each of the front-rear ends of the first base portion 81 to one side in the left-right direction. The first fitting 80 has a first projection 83 that extends linearly downward from substantially the entire other end edge of the first base portion 81 in the left-right direction.

[0080] The first fitting 80 has a first engaging portion 831 positioned on the left-right surface of the first protruding piece 83, facing the other side in the left-right direction. The first engaging portion 831 has a convex portion that protrudes to the other side in the left-right direction on the surface of the first protruding piece 83. The first fitting 80 has a second engaging portion 832 positioned directly below the first engaging portion 831 on the surface of the first protruding piece 83. The second engaging portion 832 has a recess that is recessed to one side in the left-right direction on the surface of the first protruding piece 83.

[0081] The first fitting 80 has a first mounting portion 84 located at the lower end of the first protruding piece 83. The first fitting 80 has a first locking portion 85 which is wider in the front-rear direction than other parts of the first protruding piece 83. The first fitting 80 has a bent portion 86 at one end edge in the left-right direction of the first base portion 81 which bends from the center in the front-rear direction to one side in the left-right direction.

[0082] The first fitting 80 has a second protruding piece 87 that extends downward from the outer edge in the front-rear direction of the second base 82 over substantially the entire length in the left-right direction. The first fitting 80 has a first engaging portion 871 located on the surface of the second protruding piece 87 that faces outward in the front-rear direction. The first engaging portion 871 has a convex portion that protrudes outward in the front-rear direction on the surface of the second protruding piece 87. The first fitting 80 has a second engaging portion 872 located on the surface of the second protruding piece 87 directly below the first engaging portion 871. The second engaging portion 872 has a recess that is recessed inward in the front-rear direction on the surface of the second protruding piece 87.

[0083] The first fitting 80 has a second mounting portion 88 located at the lower end of the second protruding piece 87. The first fitting 80 has a second locking portion 89 which is wider in the left-right direction than other parts of the second protruding piece 87.

[0084] As shown in Figure 6, the first contact 70 is integrally molded with the first contact holding portion 64 of the first insulator 60 by insert molding. The first contact 70 is attached to the longitudinal wall 62b. At this time, the contact portion 74 is positioned along the inner surface of the longitudinal wall 62b in the front-rear direction. The mounting portion 71 extends outward in the front-rear direction, penetrating the bottom plate portion 61. The front-rear tip of the mounting portion 71 is located outside the longitudinal wall 62b in the front-rear direction.

[0085] The first fitting 80 is press-fitted from above the first insulator 60. The first fitting 80 is attached to the outer peripheral wall 62. At this time, the first locking portion 85 locks onto the first wall portion 651 of the first fitting mounting portion 65 on the outside in the left-right direction of the short wall 62a. The first protruding piece 83 is attached to the first mounting groove 653. Similarly, the second locking portion 89 locks onto the first wall portion 651 and the second wall portion 652 of the first fitting mounting portion 65 on the outside in the front-rear direction of the long wall 62b. The second protruding piece 87 is attached to the second mounting groove 654. As a result, the first fitting 80 is held in place by the first fitting mounting portion 65.

[0086] The first base portion 81 and the second base portion 82 of the first fitting 80 are arranged along the outer perimeter wall 62. More specifically, the first base portion 81 is arranged along the short side wall 62a, and the second base portion 82 is arranged along the long side wall 62b.

[0087] The protrusions included in the first engaging portion 871 of the second protruding piece 87 project outwards from the outer peripheral wall 62 on the surface of the second protruding piece 87. In a pair of second protruding pieces 87 arranged in the front-rear direction, the protrusions of the pair of first engaging portions 871 are arranged along the front-rear outer surfaces of the opposing longitudinal walls 62b. The pair of first engaging portions 871 are arranged at the same left-right and up-down positions on the first fitting 80.

[0088] The recess included in the second engaging portion 872 of the second protruding piece 87 is positioned toward the outer peripheral wall 62 from the surface of the second protruding piece 87. In a pair of second protruding pieces 87 arranged in the front-rear direction, the recesses of the pair of second engaging portions 872 are positioned along the front-rear outer surfaces of the opposing longitudinal walls 62b. The pair of second engaging portions 872 are positioned at the same left-right and up-down positions on the first fitting 80.

[0089] When the first fitting 80 is held by the first fitting mounting portion 65 of the first insulator 60, it covers the entire short wall 62a and the left-right ends of the long wall 62b. The first mounting portion 84 is positioned along the left-right outer surface of the short wall 62a. The first mounting portion 84 extends below the lower end of the short wall 62a. The second mounting portion 88 is positioned along the front-rear outer surface of the long wall 62b. The second mounting portion 88 extends below the lower end of the long wall 62b.

[0090] The mating end face of the first fitting 80 is located on the mating side of the first connector 50 to the second connector 10, compared to the mating end face of the first contact 70. The upper surface of the first fitting 80 attached to the first insulator 60 is located above the upper surface of the first contact 70 attached to the first insulator 60.

[0091] In the first connector 50 having the structure described above, the mounting portion 71 of the first contact 70 is soldered to the circuit pattern arranged on the mounting surface of the circuit board CB1. The first mounting portion 84 and the second mounting portion 88 of the first metal fitting 80 are soldered to the pattern arranged on the said mounting surface. As a result, the first connector 50 is mounted on the circuit board CB1. Other electronic components, such as an imaging module, are mounted on the mounting surface of the circuit board CB1.

[0092] Referring to Figures 8 to 11, the configuration of the connector module 1 in the mated state, where the first connector 50 and the second connector 10 are mated with each other, will be mainly described. Figure 8 is a cross-sectional view along the line VIII-VIII in Figure 1. Figure 9 is an enlarged cross-sectional view of the area IX enclosed by the dashed line in Figure 8. Figure 10 is an external perspective view showing the first contact 70 and the second contact 30 connected to each other.

[0093] For example, with the orientation of the first connector 50 shown in Figure 8 reversed vertically, the second connector 10 and the first connector 50 are positioned so that their front-to-back and left-to-right positions are roughly aligned, and they are positioned facing each other vertically. Then, the first connector 50 is moved downward. As a result, the second connector 10 and the first connector 50 are connected to each other, and the connection state of the connector module 1 is obtained. At this time, the first insulator 60 mates with the second connector 10. The second insulator 20 mates with the first connector 50. The mating projection 22 of the second insulator 20 and the mating recess 63 of the first insulator 60 mate with each other.

[0094] As shown in Figure 9, in the mated state, the elastic contact portion 35 of the second contact 30 and the contact portion 74 of the first contact 70 come into contact, and the elastic contact piece 34, which has spring elasticity, elastically deforms inward in the front-rear direction. The first contact 70 comes into contact with the second contact 30 on one side, which is the center side of the first connector 50, with the center line in the front-rear direction of the longitudinal wall 62b as the boundary, and separates on the other side. The first contact 70 and the second contact 30 come into contact at one point by the elastic contact portion 35 and the contact portion 74 located on one side. At this time, the free end 75 of the first contact 70 and the free end 36 of the second contact 30 are both located on the same side.

[0095] The free end 75 of the first contact 70 and the free end 36 of the second contact 30 are both located on the withdrawal side, i.e., the upper side, of the first connector 50 relative to the second connector 10, with respect to the contact points of the elastic contact portion 35 and the contact portion 74. The free end 75 is located even further towards the withdrawal side than the free end 36 and is integrally molded with the bottom plate portion 61 and the longitudinal wall 62b. The free end 75 is embedded inside the bottom plate portion 61. The free end 36 is positioned on the inner surface of the fitting projection 22 in the front-rear direction in the second contact mounting groove 24. The free end 36 is positioned so as to be displaceable in the front-rear direction within the second contact mounting groove 24 in accordance with the elastic deformation of the elastic contact piece 34.

[0096] The second contact 30 is bent in an L-shape at the mounting portion 31 and extends linearly upward at the locking portion 32. The second contact 30 is bent in a U-shape at the curved portion 33 and arranged in an S-shape at the elastic contact piece 34. The first contact 70 is bent in an L-shape at the mounting portion 71 and extends linearly downward at the extension portion 72. The first contact 70 is bent in a U-shape at the folded portion 73 and extends linearly upward. The U-shaped portion of the first contact 70 is located at the folded portion 73, which improves the holding force when the first insulator 60 holds the first contact 70 by insert molding.

[0097] As can be seen from Figures 7 and 8, the outer wall 66 of the first insulator 60 extends parallel to the longitudinal wall 62b on the other side of the extension 72 of the first contact 70 over the entire area in the alignment direction of the multiple first contacts 70. The extension 72 of the first contact 70 is integrally molded with the longitudinal wall 62b and the outer wall 66, sandwiched between them. The outer wall 66 is located along the front-rear direction between the extension 72 of the first contact 70 and the curved portion 33 of the second contact 30.

[0098] As shown in Figure 9, in the mated state, the outer wall 66 of the first insulator 60 is positioned at the end of the first connector 50 on the withdrawal side relative to the second connector 10, and further out than that end, in the region R where the first contact 70 and the second contact 30 face each other on the other side. The outer wall 66 is positioned at a height greater than or equal to the height of the upper end of region R. The mated end of the outer wall 66 is spaced apart from the protrusion 27 along the mating direction. The mated end of the outer wall 66 is positioned at a vertical position approximately the same as the curved portion 33, or at a vertical position further out than the curved portion 33. The outer wall 66 extends from directly below the mounting portion 71 of the first contact 70 to the vertical region where the extension portion 72 extends. Most of the region R located between the folded portion 73 and the curved portion 33 is composed of air rather than insulators, including the first insulator 60.

[0099] In the mating state, the extension 34a of the second contact 30 is positioned such that the folded portion 73 of the first contact 70 faces the first connector 50 while being spaced apart from the side of the first connector 50 that is removed from the second connector 10. The projection 27 of the second insulator 20 protrudes further toward the side of the first connector 50 that is removed from the second connector 10 than the extension 34a of the second contact 30.

[0100] The protruding portion 27 is positioned differently from the second contact 30 in the left-right direction. The protruding portion 27 is positioned adjacent to the extension portion 34a of the second contact 30 in the left-right direction. In the bottom plate portion 21, the extension portion 34a and the protruding portion 27 are arranged alternately along the left-right direction.

[0101] The protruding portion 27 contacts the portion of the longitudinal wall 62b of the first insulator 60 located between the multiple first contacts 70 from below. At this time, the space located between the folded portion 73 and the extension portion 34a is not interposed by the second insulator 20. In addition to being above the extension portion 34a, the second insulator 20 is also not interposed below the extension portion 34a.

[0102] Figure 11 is a cross-sectional view along the line XI-XI in Figure 1.

[0103] In the fitted state, the first fitting 80 and the second fitting 40a are in contact with each other. For example, the extension 49a of the second fitting 40a and the second protruding piece 87 of the first fitting 80 are in contact. More specifically, the first engaging portion 49a1 of the extension 49a and the second engaging portion 872 of the second protruding piece 87 engage with each other based on the uneven structure. The second engaging portion 49a2 of the extension 49a and the first engaging portion 871 of the second protruding piece 87 engage with each other based on the uneven structure.

[0104] At this time, the spring-elastic extension portion 49a elastically deforms outward in the front-rear direction. In the fitted state, the extension portion 49a contacts the first fitting 80 and elastically deforms toward the outer peripheral wall 23 of the second insulator 20. The second fitting 40a and the first fitting 80 contact each other at two points on both the front and rear sides by the extension portion 49a and the second protruding piece 87.

[0105] When the extension portion 49a elastically deforms toward the outer peripheral wall 23 in the fitted state, the contacted portion 267 of the second insulator 20 comes into contact with the surface of the extension portion 49a facing toward the outer peripheral wall 23. More specifically, the inclined surface 267a of the contacted portion 267 comes into contact with the lower edge of the surface of the extension portion 49a facing toward the outer peripheral wall 23. In this way, the corner portion of the tip of the extension portion 49a facing toward the outer peripheral wall 23 is separated from the inclined surface 267a of the contacted portion 267 in the non-fitted state, and comes into contact with the inclined surface 267a of the contacted portion 267 in the fitted state.

[0106] The first fitting 80 receives a biasing force directed away from the outer wall 23 from the elastically deformed extension 49a toward the outer wall 23. The extension 49a that elastically deforms toward the outer wall 23 and comes into contact with the contacted portion 267 receives a resistive force from the inclined surface 267a of the contacted portion 267. Through this biasing force and resistive force, the contact pressure of the second fitting 40a on the first fitting 80 is obtained.

[0107] The upper surface of the second base portion 42b of the third fitting 40b is on the same plane as the upper surface of the bottom plate portion 21. The upper surface of the second base portion 42b is exposed above the second portion 252 of the bottom plate portion 21.

[0108] In Figure 11, the plate thickness of the third fitting 40b is approximately the same as the plate thickness of the second fitting 40a. However, it is not limited to this, and the plate thickness of the third fitting 40b may be greater than that of the second fitting 40a, for example, even if the third fitting 40b and the second fitting 40a are made of the same material, so that the strength of the third fitting 40b is higher than that of the second fitting 40a.

[0109] In the fitted state, the first fitting 80 and the second fitting 40a are in contact with each other. For example, the bent portion 46a of the second fitting 40a and the first protruding piece 83 of the first fitting 80 are in contact. More specifically, the first engaging portion 46a1 of the bent portion 46a and the second engaging portion 832 of the first protruding piece 83 engage with each other based on the concave and convex structure. The second engaging portion 46a2 of the bent portion 46a and the first engaging portion 831 of the first protruding piece 83 engage with each other based on the concave and convex structure.

[0110] At this time, the spring-elastic bent portion 46a elastically deforms outward in the left-right direction. In the fitted state, the bent portion 46a contacts the first fitting 80 and elastically deforms toward the outer peripheral wall 23 of the second insulator 20. The second fitting 40a and the first fitting 80 contact at one point in the left-right direction by the bent portion 46a and the first protruding piece 83.

[0111] According to the connector module 1 of the above embodiment, it is possible to increase the impedance even in the miniaturized first connector 50 and second connector 10. In the connector module 1, the first contact 70 and the second contact 30 are in contact with each other on one side of the longitudinal wall 62b and separated on the other side. At this time, the free ends 75 and 36 are both located on the same side as the contact points of the first contact 70 and the second contact 30. With this configuration, the connector module 1 can shorten the stub by bringing the free ends 75 and 36 of the first contact 70 and the second contact 30 closer together. More specifically, the connector module 1 can shorten the distance from the contact point of the first contact 70 to the free end 75. The connector module 1 can shorten the distance from the contact point of the second contact 30 to the free end 36. As a result, the connector module 1 can increase the impedance of the first contact 70 and the second contact 30.

[0112] In the connector module 1, the width of the extension portion 72 is smaller than the width of the folded portion 73 in the direction of arrangement of the multiple first contacts 70, thereby increasing the inductance component L in the first contacts 70. Therefore, the connector module 1 can increase the impedance in the first contacts 70. If the first contacts 70 are press-fitted into the first insulator 60, they may have a wide locking portion for engaging with the first insulator 60, which could reduce the impedance at the locking portion. In the first connector 50, because the first contacts 70 are integrally molded with the first insulator 60 by insert molding, the width of the extension portion 72 can be reduced without having such a wide locking portion.

[0113] In the connector module 1, the folded portion 73 of the first contact 70 is positioned wider in the left-right direction than the extended portion 72, thereby increasing the area of ​​the metal portion at the mating end face of the longitudinal wall 62b of the first insulator 60. As a result, the connector module 1 can improve the strength of the first connector 50.

[0114] The first connector 50 has an outer wall 66 that extends parallel to the longitudinal wall 62b on the other side of the extension portion 72. This allows the connector module 1 to hold the first contact 70 and the second contact 30 separated in the front-rear direction on the other side when the first connector 50 and the second connector 10 are mated. This allows the first contact 70 and the second contact 30 to contact each other with respect to the longitudinal wall 62b on only one side. Therefore, compared to the case where the first contact 70 and the second contact 30 contact each other on both sides in the front-rear direction, the path length through which the transmission signal flows can be substantially increased, and the L component can be increased. In addition, the stub generated during mating is reduced. As a result, it is possible to increase the impedance of the first contact 70 and the second contact 30.

[0115] The connector module 1 achieves a capacitor-like effect between the curved portion 33, the extended portion 72, and the folded portion 73 by separating the first contact 70 and the second contact 30 in the front-rear direction. If the capacitance is C, the dielectric constant decreases and the C component becomes smaller because most of the region R is composed of air. As a result, it becomes possible to increase the impedance at the first contact 70 and the second contact 30.

[0116] In the connector module 1, the first connector 50 has an outer wall 66, which improves the holding strength of the first contact 70 by the first insulator 60 based on insert molding. Therefore, the first connector 50 can stably hold the first contact 70 with the first insulator 60. In addition, even in its miniaturized state, the connector module 1 can reduce solder buildup from the mounting portion 71 of the first contact 70. As a result, the reliability of the connector module 1 can be improved.

[0117] The first connector 50 has an outer wall 66. This allows the connector module 1 to make initial contact with the second insulator 20 even if the first connector 50 is tilted at an angle relative to the second connector 10 in a plane extending in the front-rear and left-right directions when the first connector 50 is mated with the second connector 10. Even in such an oblique mating situation, the connector module 1 can reduce contact between the first contact 70 and the second insulator 20 and second contact 30, thereby reducing damage to the second connector 10. Therefore, the reliability of the connector module 1 as a product can be improved.

[0118] The first insulator 60 has an outer wall 66, which makes it possible to arrange the outer wall 66 integrally with the longitudinal wall 62b. The connector module 1 facilitates the arrangement of the outer wall 66 in the first connector 50 and facilitates the manufacturing of the first connector 50.

[0119] In the fitted state, the outer wall 66 is positioned at the withdrawal end of region R and further out from that end, so that most of region R is composed of air. This reduces the dielectric constant in region R and decreases the C component. As a result, it becomes possible to increase the impedance at the first contact 70 and the second contact 30.

[0120] The connector module 1 has a protruding portion 27 on the second connector 10 that protrudes further outward than the extension portion 34a, making it easy to separate the first contact 70 and the second contact 30 in the vertical direction. By separating the first contact 70 and the second contact 30 in the vertical direction, the connector module 1 can obtain an effect similar to that of a capacitor between the extension portion 34a and the folded portion 73. If the capacitance is C, the dielectric constant decreases and the C component becomes smaller because the space between the folded portion 73 and the extension portion 34a is composed of air. As a result, it becomes possible to increase the impedance at the first contact 70 and the second contact 30.

[0121] The connector module 1 does not have a second insulator 20 interposed above or below the extension portion 34a, thus maintaining the low profile of the second connector 10 while increasing the distance from the upper surface of the extension portion 34a to the upper surface of the protruding portion 27. Consequently, the gap between the folded portion 73 and the extension portion 34a in the mating direction also increases. As a result, the gap between the capacitors increases and the capacitance C decreases, making it possible to increase the impedance at the first contact 70 and the second contact 30.

[0122] The connector module 1, with the second connector 10 having a protrusion 27, can reduce the bending of the central part of the first insulator 60 along the left-right direction when the first connector 50 is mated with the second connector 10, thereby reducing damage to the first insulator 60. The connector module 1 allows not only the second metal fitting 40a of the second connector 10 but also the protrusion 27 to come into contact with the first insulator 60 of the first connector 50 during mating. This reduces the load applied to the first insulator 60 during mating.

[0123] The second insulator 20 has a protrusion 27, which makes it possible to arrange the protrusion 27 integrally with the bottom plate 21. The connector module 1 facilitates the arrangement of the protrusion 27 in the second connector 10 and facilitates the manufacturing of the second connector 10.

[0124] In the connector module 1, the end face of the first fitting 80 that contacts the second fitting 40a in the mating state is located on the mating side of the end face of the first contact 70 in the mating state, making it easy to separate the first contact 70 and the second contact 30. Even if the second connector 10 does not have a protrusion 27, the connector module 1 can still separate the first contact 70 and the second contact 30.

[0125] In addition, the connector module 1 can increase the length of the first fitting 80 and the second fitting 40a along the mating direction. The connector module 1 can increase the effective mating length of the first fitting 80 and the second fitting 40a. The effective mating length of the first fitting 80 corresponds, for example, to the vertical width from the second engaging portion 872 to the mating side surface of the second base portion 82. The effective mating length of the second fitting 40a corresponds, for example, to the width along the extension portion 49a from the first engaging portion 49a1 to the removal side surface of the second base portion 42a.

[0126] As a result, the spring length of the spring-elastic extension portion 49a in the second fitting 40a is also increased, improving the contact reliability between the first fitting 80 and the second fitting 40a in the mated state. The connector module 1 can maintain the overall contact reliability even when the first contact 70 and the second contact 30 are in contact at only one point.

[0127] Since the first contact 70 is integrally molded with the first insulator 60 by insert molding, the holding strength of the first contact 70 by the first insulator 60 is improved.

[0128] Because the second insulator 20 has a contacted portion 267, the extension portion 49a that elastically deforms toward the outer peripheral wall 23 in the mated state comes into contact with the contacted portion 267. As a result, the contact pressure of the second fitting 40a against the first fitting 80 increases due to the biasing force generated from the extension portion 49a that elastically deforms toward the outer peripheral wall 23 toward the opposite side of the outer peripheral wall 23, and the resistance force received by the extension portion 49a that elastically deforms toward the outer peripheral wall 23 and comes into contact with the contacted portion 267. The second connector 10 can stably hold the first connector 50.

[0129] The contacted portion 267 has an inclined surface 267a, which allows it to make contact with the elastically deformable extension portion 49a towards the outer peripheral wall 23 at an earlier stage during the fitting process, compared to when it is arranged as a plane perpendicular to the bottom plate portion 21. As a result, the second connector 10 exhibits the above-mentioned effects regarding the retention of the first connector 50 more significantly.

[0130] The second connector 10 has a protrusion on its first engaging portion 49a1, which allows it to engage with the first engaging portion 871 of the first fitting 80 of the first connector 50 at the protrusion on the first engaging portion 49a1 when mated with the first connector 50, thereby improving the click sensation. In addition, the second connector 10 can also improve the extraction force when removing the first connector 50 from the second connector 10 while mated.

[0131] The second fitting 40a has an elastically deformable extension 49a that contacts the first fitting 80 when fitted, and the elastic force in the extension 49a makes it possible to stably maintain the connection with the first fitting 80. Therefore, electrical conductivity between the second fitting 40a and the first fitting 80 is stably maintained when fitted.

[0132] In the second connector 10, the third fitting 40b attached to the mating projection 22 and the second fitting 40a attached to the outer peripheral wall 23 are made of different materials. As a result, compared to conventional technology in which the fittings are manufactured integrally, the impact of contact between the fittings and the first connector 50 during mating is reduced. For example, even if the fittings and the first connector 50 come into contact with each other on one side of the mating projection 22 and the outer peripheral wall 23, the impact of that contact on the other side is reduced. This reduces damage to the fittings, including the second fitting 40a and the third fitting 40b. Reduced damage to the fittings also reduces damage to the second insulator 20 to which the fittings are attached. As a result, the reliability of the second connector 10 as a product is improved.

[0133] Even if mating is performed with the first connector 50 misaligned relative to the second connector 10, and the first connector 50 comes into contact with the second fitting 40a on the outer peripheral wall 23 side during mating, causing the second fitting 40a and the outer peripheral wall 23 to deform by tilting outward in the left-right direction, the impact on the mating projection 22 side is reduced. Because the second fitting 40a and the third fitting 40b are made of different materials, the deformation of the third fitting 40b is reduced. Even if the first connector 50 comes into contact with the third fitting 40b on the mating projection 22 side during mating, causing the third fitting 40b and the mating projection 22 to deform by recessing inward in the left-right direction, the impact on the outer peripheral wall 23 side is reduced. Because the second fitting 40a and the third fitting 40b are made of different materials, the deformation of the second fitting 40a is reduced. In this way, each fitting exhibits independent and separate behavior on one side of the mating projection 22 and the outer peripheral wall 23. Therefore, the transmission of behavior to the other side is reduced. As a result, the entire metal fitting can reliably perform the desired function, thus reducing damage.

[0134] As described above, damage to the metal fittings and the second insulator 20 is reduced, thereby reducing the longitudinal displacement of the second connector 10 between the second connector 10 and the first connector 50 during and after mating. This ensures that electrical conductivity between the second contact 30 and the first contact 70 is accurately achieved according to the original design. In addition, rattling of the connector module 1 after mating is reduced. The function of positioning one of the second connector 10 relative to the other of the first connector 50 is maintained. As a result, one is less likely to come loose from the other, improving the reliability of the connector module 1 as a product.

[0135] In the second connector 10, since the second fitting 40a and the third fitting 40b are made of different materials, it is possible to make the strength of one of the second fitting 40a and the third fitting 40b even higher than the strength of the other. In the second connector 10, for example, the second fitting 40a and the third fitting 40b are attached to different locations and for different purposes, such as the mating projection 22 and the outer peripheral wall 23, and each fitting can be manufactured with appropriate strength to suit its location and purpose. For example, if the fittings are manufactured integrally as in the prior art, if the strength of the fitting has to be reduced on one side of the mating projection 22 and the outer peripheral wall 23, the strength of the fitting will also be reduced on the other side.

[0136] For example, the main purpose of the third fitting 40b attached to the fitting projection 22 is to improve the robustness of the fitting projection 22. On the other hand, one of the purposes of the second fitting 40a attached to the outer peripheral wall 23 is to obtain electrical conductivity by making contact with the first fitting 80 in the fitted state. For this purpose, the second fitting 40a is provided with an elastically deformable extension 49a.

[0137] Therefore, the second fitting 40a may be made of a material with sufficient strength to provide spring properties, while the third fitting 40b may be made of a material with even greater strength. In the second connector 10, each fitting can be manufactured with appropriate strength for its respective purpose, corresponding to the second fitting 40a and the third fitting 40b. For example, if the fittings are manufactured integrally as in the prior art, the overall strength of the fitting will decrease due to the placement of elastically deformable contact pieces on the outer peripheral wall side, and the robustness of the mating protrusion will also decrease.

[0138] By using a different material for the third fitting 40b than for the second fitting 40a, it is possible to easily manufacture each fitting such that the strength of one of the second fitting 40a and the third fitting 40b is higher than the strength of the other. For example, it becomes possible to appropriately select the material of each fitting according to the purpose of the second fitting 40a and the third fitting 40b as described above.

[0139] Because the strength of the material of the third fitting 40b is higher than that of the material of the second fitting 40a, the robustness of the mating projection 22 to which the third fitting 40b is attached is improved. Therefore, damage to the mating projection 22 of the second insulator 20 to which the third fitting 40b is attached is reduced. As a result, the reliability of the second connector 10 as a product is improved.

[0140] Because the plate thickness of the third fitting 40b is greater than that of the second fitting 40a, even if the second fitting 40a and the third fitting 40b are made from the same material, the strength of the third fitting 40b will be higher than that of the second fitting 40a. As a result, the robustness of the fitting projection 22 to which the third fitting 40b is attached is improved in the same manner as described above.

[0141] In the second connector 10, the robustness of the third metal fitting 40b is improved by having a mounting portion 44b to which the third metal fitting 40b is mounted on the circuit board CB2. Even if a load is applied to the third metal fitting 40b, its deformation is reduced, and the shape and dimensional accuracy of the second connector 10 are maintained even during mating. For example, the robustness of the mating projection 22 to which the third metal fitting 40b is attached is improved. Therefore, damage such as deformation of the mating projection 22 is reduced, and the effects on longitudinal displacement and looseness of the second connector 10 described above are obtained.

[0142] Because the mounting portion 44b includes the bottom surface on the circuit board CB2 side, the external force acting on the third metal fitting 40b can be absorbed at the mounting portion 44b. When the mounting portion 44b is mounted on the circuit board CB2, the third metal fitting 40b is fixed to the circuit board CB2, and even if an external force acts on the third metal fitting 40b, the impact is absorbed at the mounting portion 44b. Therefore, the robustness of the third metal fitting 40b along the longitudinal direction of the second connector 10 is improved. As a result, the robustness of the mating projection 22 along the longitudinal direction of the second connector 10 is also improved.

[0143] Since the first base portion 41b and the second base portion 42b are integrally arranged to form a crank shape as a whole, the entire third fitting 40b is integrated with the second insulator 20 along the shape of the end portion of the fitting projection 22 and the bottom plate portion 21. Therefore, the holding strength of the third fitting 40b with respect to the second insulator 20 is improved.

[0144] The first mounting portion 44a of the second metal fitting 40a is positioned on both sides of the third metal fitting 40b in the short-side direction of the second connector 10. The second mounting portion 48a of the second metal fitting 40a is also positioned on both sides of the third metal fitting 40b in the short-side direction of the second connector 10. As a result, the mounting strength of the second metal fitting 40a to the circuit board CB2 is improved. This improves the robustness of the second metal fitting 40a and the short-side wall 23a in the left-right direction.

[0145] Since the pair of first mounting parts 44a are positioned at approximately the same left-right position as mounting part 44b, the three mounting parts are located on a straight line along the front-to-back direction. This improves the mounting strength of the second connector 10 to the circuit board CB2. For example, even if the first connector 50 is mated to the second connector 10 with a predetermined angle offset about the vertical axis, the mounting of the second connector 10 to the circuit board CB2 is maintained. Similarly, even if the circuit board CB2 on which the second connector 10 is mounted rotates after mating, the mounting of the second connector 10 to the circuit board CB2 is maintained. Therefore, the robustness of the second connector 10 mounted on the circuit board CB2 is improved.

[0146] The attachment of a pair of second fittings 40a to a pair of short walls 23a improves the robustness of the short walls 23a at both ends of the outer perimeter wall 23 in the left-right direction. Consequently, damage to the short walls 23a of the second insulator 20 to which the pair of second fittings 40a are attached is further reduced. As a result, the reliability of the second connector 10 as a product is further improved.

[0147] It will be apparent to those skilled in the art that this disclosure can be implemented in other predetermined forms besides the embodiments described above without deviating from its spirit or essential features. Therefore, the prior description is illustrative and not limiting. The scope of the disclosure is defined not by the prior description but by the added claims. Any modifications within their equivalent scope are included therein.

[0148] For example, the shape, size, arrangement, orientation, and number of each component described above are not limited to those shown in the above description and drawings. The shape, size, arrangement, orientation, and number of each component may be configured arbitrarily, as long as they can achieve their function.

[0149] The assembly method of the second connector 10 and the first connector 50 described above is not limited to the above description. The assembly method of the second connector 10 and the first connector 50 may be any method as long as they can be assembled so that their respective functions are performed. For example, in the second connector 10, at least one of the second contact 30 and the second fitting 40a may be integrally molded with the second insulator 20 by insert molding rather than press-fitting. The third fitting 40b may be attached to the second insulator 20 by press-fitting rather than insert molding. For example, in the first connector 50, the first contact 70 may be attached to the first insulator 60 by press-fitting rather than insert molding. The first fitting 80 may be integrally molded with the first insulator 60 by insert molding rather than press-fitting.

[0150] In the above embodiment, the first contact 70 was described as having a folded portion 73 connecting the extended portion 72 and the free end 75, but it is not limited to this. The first contact 70 does not have to have a folded portion 73. In this case, the first contact 70 as a whole may be arranged in an L shape. The overall shape of the first contact 70 may be based on a mounting portion 71 that extends outward in an L shape in the front-rear direction, and an extended portion 72 that extends linearly upward from the upper end of the mounting portion 71.

[0151] In the above embodiment, the free end 36 of the second contact 30 is located further to one side than the elastic contact portion 35, but is not limited to this. For example, the elastic contact piece 34 of the second contact 30 does not have to be arranged in an S-shape. The elastic contact piece 34 may extend significantly to one side, bend upward, and then bend back to the other side so that the elastic contact portion 35 and the free end 36 are located at substantially the same front-to-back position.

[0152] In the above embodiment, the width of the extension portion 72 was described as being smaller than the width of the folded portion 73, but this is not limited to this. For example, the width of the extension portion 72 may be about the same as the width of the folded portion 73.

[0153] In the above embodiment, the first connector 50 was described as having an outer wall 66 in the entire area in the direction of arrangement of the plurality of first contacts 70, but it is not limited to this. The first connector 50 may have an outer wall 66 in a part of the area in the direction of arrangement of the plurality of first contacts 70, or it may not have an outer wall 66 at all.

[0154] In the above embodiment, the first insulator 60 was described as having an outer wall 66, but is not limited thereto. The outer wall 66 may be constructed separately from the first insulator 60, either as part of the first insulator 60 or in addition to being constructed as part of the first insulator 60, based on another material such as resin or metal.

[0155] In the above embodiment, the outer wall 66 was described as being located at the end of the region R on the removal side and on the side further away from that end, but it is not limited to this. The outer wall 66 may also be located in the region R.

[0156] In the above embodiment, the second connector 10 was described as having protrusions 27 in the entire area in the direction of arrangement of the plurality of second contacts 30, but it is not limited to this. The second connector 10 may have protrusions 27 in a part of the area in the direction of arrangement of the plurality of second contacts 30, or it may not have protrusions 27 at all.

[0157] In the above embodiment, the second insulator 20 was described as having a protrusion 27, but is not limited thereto. The protrusion 27 may be configured separately from the second insulator 20, either as part of the second insulator 20 or in addition to being configured as part of the second insulator 20, based on another material such as resin or metal.

[0158] In the above embodiment, an outer wall 66 protruding in the front-rear direction is arranged on the first insulator 60, and a protruding portion 27 protruding in the up-down direction is arranged on the second insulator 20, but this is not limited to this. A configuration corresponding to the outer wall 66 protruding in the front-rear direction may be arranged on the second insulator 20. For example, such a configuration may extend in the left-right direction along the inside of the longitudinal wall 23b of the second insulator 20. A configuration corresponding to the protruding portion 27 protruding in the up-down direction may be arranged on the first insulator 60. For example, instead of the upper surface of the longitudinal wall 62b being flush with the upper surface of the folded portion 73 of the first contact 70 as in the above embodiment, it may protrude one level above the upper surface of the folded portion 73 of the first contact 70, and such a configuration may be obtained as such a protruding portion.

[0159] In the above embodiment, the first contact 70 is arranged such that the fracture surface faces left to right in all its components, but it is not limited to this. The first contact 70 may be arranged such that the rolled surface faces left to right in all its components, or it may be arranged such that the fracture surface faces left to right in some parts and the rolled surface faces left to right in other parts.

[0160] In the above embodiment, the second contact 30 is arranged such that the fracture surface faces left to right in all its components, but it is not limited to this. The second contact 30 may be arranged such that the rolled surface faces left to right in all its components, or it may be arranged so that the fracture surface faces left to right in some parts and the rolled surface faces left to right in other parts.

[0161] Although it has been explained that the end face of the first fitting 80 in the fitting direction is located on the fitting side of the end face of the first contact 70 in the fitting direction, this is not limited to this. The end face of the first fitting 80 in the fitting direction may be on the same plane as the end face of the first contact 70 in the fitting direction, or it may be located on the withdrawal side of the end face of the first contact 70 in the fitting direction.

[0162] In the above embodiment, the upper surface of the portion of the first fitting mounting portion 65 that extends linearly in the left-right direction between the first wall portion 651 and the second wall portion 652 is described as being at the same height as the upper surface of the first contact 70 held by the first insulator 60, but this is not limited to this. The upper surface of the above portion may be located even higher than the upper surface of the first contact 70 held by the first insulator 60, such that the end face of the first fitting 80 in the fitting direction is located on the fitting side of the end face of the first contact 70 in the fitting direction.

[0163] In the above embodiment, the extensions 49a are described as being arranged in pairs on the second fitting 40a, but this is not limited to this. The extensions 49a may be arranged in pairs or more at any position on the second fitting 40a, or they may be arranged in any number of one or more at any position without being arranged in pairs.

[0164] In the above embodiment, the extension portion 49a was described as being located on the longitudinal wall 23b, but is not limited thereto. The extension portion 49a may be located on the short wall 23a instead of, or in addition to, the longitudinal wall 23b.

[0165] In the above embodiment, the second insulator 20 was described as having a contacted portion 267, but it is not limited to this. The second insulator 20 does not have to have a configuration such as the contacted portion 267. The extension portion 49a of the second fitting 40a does not have to be in contact with the second insulator 20 when fitted.

[0166] In the above embodiment, the contacted portion 267 was described as having an inclined surface 267a that slopes inward toward the longitudinal wall 23b as it approaches the fitting side, but it is not limited to this. The contacted portion 267 may have any other configuration that is located further inward toward the outer peripheral wall 23 on the fitting side. For example, instead of a configuration that slopes continuously toward the inner side of the outer peripheral wall 23 like the inclined surface 267a, the contacted portion 267 may have a configuration that changes in a stepped manner as it approaches the fitting side.

[0167] The contacted portion 267 does not necessarily have to be located further inside the outer peripheral wall 23 on the fitting side. For example, the contacted portion 267 may have a plane perpendicular to the bottom plate portion 21 instead of the inclined surface 267a. The contacted portion 267 may be arranged to rise in a mountain-like shape by a curved surface arranged with any curvature instead of the perpendicular plane and the inclined surface 267a. Furthermore, the contacted portion 267 may be located on the short wall 23a instead of, or in addition to, the long wall 23b.

[0168] In the above embodiment, the corner on the outer peripheral wall 23 side that contacts the contacted portion 267 in the extended portion 49a is described as being arranged at a right angle, but this is not limited to this. The corner may have an R shape. This reduces damage to the second insulator 20 caused by contact between the second metal fitting 40a and the second insulator 20 in the contacted portion 267. Therefore, the contact pressure applied from the extended portion 49a to the first connector 50 is maintained for a longer period of time. The robustness of the second connector 10 is improved, and the reliability of the second connector 10 as a product is improved.

[0169] In the above embodiment, the second fitting 40a and the third fitting 40b were described as being separate from each other, but this is not limited to this. The second fitting 40a and the third fitting 40b may not be separate from each other but connected. In this case, the second fitting 40a and the third fitting 40b may be manufactured so that their respective strengths differ from each other within the entire integrated fitting. For example, the integrated fitting including the second fitting 40a and the third fitting 40b may be made of a gradient functional material. More specifically, the material of the third fitting 40b may be different from the material of the second fitting 40a so that its strength is higher than the strength of the material of the second fitting 40a. For example, the integrated fitting including the second fitting 40a and the third fitting 40b may be manufactured so that the plate thickness varies. More specifically, the plate thickness of the third fitting 40b may be greater than the plate thickness of the second fitting 40a.

[0170] In the above embodiment, it was explained that the strength of the third fitting 40b is even higher than the strength of the second fitting 40a, but this is not limited to this. The strength of the second fitting 40a may also be even higher than the strength of the third fitting 40b.

[0171] In the above embodiment, it was explained that the plate thickness of the third fitting 40b may be greater than that of the second fitting 40a so that the strength of the third fitting 40b is greater than that of the second fitting 40a, but this is not limited to this. For example, even if the plate thickness of the third fitting 40b is smaller than that of the second fitting 40a, the strength of the third fitting 40b may be greater than that of the second fitting 40a.
