[0001] The present disclosure relates to a connector. Background Art

[0002] A connector as described in Patent Document 1 has been conventionally known. This connector (socket connector 2) includes terminals and a housing. The terminals are held in the housing by being inserted into the housing.

[0004] Patent Documents

[0005] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2017-135122 Summary of the Invention

[0006] In the connector of Patent Document 1, it is desired to increase the design freedom of the holding portion that holds the terminals.

[0007] That is, in this connector, one housing (socket housing 6) holds the terminals. Therefore, due to the housing forming, the holding portion is divided into a holding portion on one end side (mounting groove 6a3, mounting hole 6b1) and a holding portion on the other end side (mounting groove 6c2). Thereby, the elongation of the holding portion is suppressed, and it is easy to form the holding portion during housing forming. When specifically described, by suppressing the elongation of the holding portion, the die member for forming the holding portion used during housing forming does not have to be formed long. Therefore, the member is less likely to be damaged.

[0008] However, instead of being easy to form the holding portion in this connector, a relatively large space is formed at the center in the width direction (inter-column direction) of the lower part of the housing. This space is the part where the die member is located during housing forming. Moreover, a part of the holding portion on one end side held by the terminals is exposed in this space. Therefore, the impedance of the exposed portion in the terminals is higher than that of the other parts of the terminals.

[0009] An object of the present disclosure is to increase the design freedom of the holding portion that holds the terminals in a connector including terminals and a housing into which the terminals are inserted, and to easily adjust connector characteristics such as impedance.

[0010] The connector according to the first aspect includes terminals and a housing into which the terminals are inserted. The housing is configured to include a first housing and a second housing. The first housing has a first side holding portion that holds a part of the terminals, and the second housing has a second side holding portion that holds the other part of the terminals.

[0011] In addition, in this specification, "holding" of the housing with respect to a part of the terminals means restricting the movement of a part of the terminals in two or more directions by abutting or approaching from two or more directions including two directions that are opposite to each other with respect to a part of the terminals.

[0012] In this method, the connector includes a terminal and a housing into which the terminal is inserted. The housing is configured to include a first housing and a second housing. The first housing has a first-side holding portion that holds a part of the terminal, and the second housing has a second-side holding portion that holds the other part of the terminal.

[0013] That is, the holding portions that hold the terminal are formed by the first housing and the second housing. Therefore, compared with the method in which the entire holding portion of the terminal is held by one housing, the degree of freedom in designing the holding portion is increased in terms of the nature of housing forming by a mold. When the degree of freedom in designing the holding portion is increased, it is easy to adjust connector characteristics such as impedance.

[0014] The connector according to the second method is the connector according to the first method, in which the first-side holding portion is configured to include a first-side surrounding portion that surrounds the terminal, and the second-side holding portion is configured to include a second-side surrounding portion that surrounds the terminal.

[0015] In this method, the first-side holding portion is configured to include a first-side surrounding portion that surrounds the terminal, and the second-side holding portion is configured to include a second-side surrounding portion that surrounds the terminal. That is, the first-side holding portion and the second-side holding portion are configured to commonly include a surrounding portion that surrounds the terminal.

[0016] Therefore, for example, compared with the method in which the first-side holding portion is configured to include a surrounding portion and the second-side holding portion is not configured to include a surrounding portion, an increase in the impedance of the portion of the second housing held among the terminals can be suppressed.

[0017] The connector according to the third method is the connector according to the first method, in which the first-side holding portion and the second-side holding portion are on a straight line.

[0018] In this method, the first-side holding portion and the second-side holding portion are on a straight line.

[0019] Therefore, it is not necessary to form a bent portion between the portion of the terminal held by the first-side holding portion and the portion held by the second-side holding portion.

[0020] The connector according to the fourth method is the connector according to the second method, in which the first-side surrounding portion and the second-side surrounding portion are on a straight line.

[0021] In this method, the first-side surrounding portion and the second-side surrounding portion are on a straight line.

[0022] Therefore, when aligning the first housing and the second housing with each other during manufacturing of the connector, the first-side surrounding portion and the second-side surrounding portion are on a straight line. Therefore, the terminal can be inserted along this straight line.

[0023] The connector according to the fifth mode is such that, in the fourth mode, the distance between the first-side surrounding portion and the second-side surrounding portion is shorter than either one of the first-side surrounding portion and the second-side surrounding portion that is shorter.

[0024] In this mode, the distance between the first-side surrounding portion and the second-side surrounding portion is short (specifically, shorter than either one of the first-side surrounding portion and the second-side surrounding portion that is shorter).

[0025] Therefore, the length of the portion between the first-side surrounding portion and the second-side surrounding portion among the terminals, that is, the portion not surrounded by the housing, becomes shorter. As a result, compared with the mode in which this length is longer, the section where the impedance is likely to increase can be shortened.

[0026] The connector according to the sixth mode is such that, in any one of the first to fifth modes, the first housing is a fitting housing that fits with a connection object, the second housing is a mounting housing disposed between the first housing and the substrate, and the terminals are inserted into the housing with the reverse fitting direction as the insertion direction.

[0027] In this mode, the first housing is a fitting housing that fits with a connection object, and the second housing is a mounting housing disposed between the first housing and the substrate. The terminals are inserted into the housing with the reverse fitting direction as the insertion direction.

[0028] Therefore, this mode is suitable for a connector having a large dimension in the fitting direction.

[0029] The connector according to the seventh mode is such that, in any one of the first to sixth modes, a plurality of terminals are provided, and the plurality of terminals include a plurality of one-side terminals arranged in the pitch direction on one side in the inter-column direction and a plurality of the other-side terminals arranged in the pitch direction on the other side in the inter-column direction. The first housing has a protruding wall that protrudes in the reverse fitting direction and extends in the pitch direction, and a plurality of grooves for holding the plurality of one-side terminals are formed on the wall surface on the one-side in the inter-column direction of the protruding wall, and a plurality of grooves for holding the plurality of the other-side terminals are formed on the wall surface on the other side in the inter-column direction of the protruding wall.

[0030] In this mode, a plurality of terminals are provided. The plurality of terminals include a plurality of one-side terminals arranged in the pitch direction on one side in the inter-column direction and a plurality of the other-side terminals arranged in the pitch direction on the other side in the inter-column direction. The first housing has a protruding wall that protrudes in the reverse fitting direction and extends in the pitch direction, and a plurality of grooves for holding the plurality of one-side terminals are formed on the wall surface on the one-side in the inter-column direction of the protruding wall, and a plurality of grooves for holding the plurality of the other-side terminals are formed on the wall surface on the other side in the inter-column direction of the protruding wall.

[0031] Therefore, this mode is applicable to a multi-pole socket connector.

[0032] The connector according to the eighth mode is in any one of the first to seventh modes, wherein the first housing is a fitting housing that fits with an object to be connected, the terminals are inserted into the housing from the second housing side among the first housing and the second housing with the anti-fitting direction as the insertion direction, the second-side holding portion is configured to include a second-side surrounding portion that surrounds the terminals, and one end on the fitting direction side of the second-side surrounding portion is located within a range of 20% on the connector fitting direction side.

[0033] It should be noted that the "range of 20% on the connector fitting direction side" means a range of 20% on the fitting side of the connector when the dimension in the fitting direction of the connector is set to 100%.

[0034] In this mode, the first housing is a fitting housing that fits with an object to be connected. The terminals are inserted into the housing from the second housing side among the first housing and the second housing with the anti-fitting direction as the insertion direction.

[0035] Moreover, the second-side holding portion is configured to include a second-side surrounding portion that surrounds the terminals, and one end on the fitting direction side of the second-side surrounding portion is located within a range of 20% on the connector fitting direction side.

[0036] Therefore, the portion on the fitting direction side of the terminals can be effectively surrounded by the second surrounding portion. Thus, for example, compared with the connector in Patent Document 1 where the portion on the fitting direction side (lower part) of the terminals is exposed, an increase in impedance in the portion on the fitting direction side of the terminals can be suppressed.

[0037] The connector according to the ninth mode is in any one of the first to eighth modes, wherein the first housing is a fitting housing that fits with an object to be connected, the terminals are inserted into the housing from the second housing side among the first housing and the second housing with the anti-fitting direction as the insertion direction, and the second-side holding portion is constituted only by a second-side surrounding portion that surrounds the terminals.

[0038] In this mode, the first housing is a fitting housing that fits with an object to be connected. The terminals are inserted into the housing from the second housing side among the first housing and the second housing with the anti-fitting direction as the insertion direction.

[0039] Moreover, the second-side holding portion is constituted only by a second-side surrounding portion that surrounds the terminals.

[0040] Therefore, the portion on the fitting direction side of the terminals can be effectively surrounded by the second housing. Thus, for example, compared with the connector in Patent Document 1 where the portion on the fitting direction side (lower part) of the terminals is exposed, an increase in impedance in the portion on the fitting direction side of the terminals can be suppressed.

[0041] This method is suitable for the case where the connector is relatively long in the fitting direction. In addition, in this method, by making the second housing and the second side surrounding portion longer in the fitting direction, the surrounded portion of the terminal can be extended.

[0042] In the connector according to the tenth method, in any of the first to ninth methods, the terminal has a first side press-fitting portion press-fitted into the first housing and a second side press-fitting portion press-fitted into the second housing.

[0043] In this method, the terminal has a first side press-fitting portion press-fitted into the first housing and a second side press-fitting portion press-fitted into the second housing.

[0044] Therefore, the separation of the first housing and the second housing is suppressed by the terminal.

[0045] In the connector according to the eleventh method, in any of the first to tenth methods, the terminal is inserted into the housing from the second housing side of the first housing or the second housing. A plurality of the terminals are provided, and the plurality of terminals are configured to include signal terminals and power supply terminals. The number of the signal terminals is larger than the number of the power supply terminals. The signal terminal has a first side press-fitting portion press-fitted into the first housing and a second side press-fitting portion press-fitted into the second housing. The power supply terminal has a second side press-fitting portion press-fitted into the second housing and does not have a first side press-fitting portion press-fitted into the first housing.

[0046] In this method, the signal terminal and the power supply terminal are inserted into the housing from the second housing side of the first housing or the second housing. The signal terminal has a first side press-fitting portion press-fitted into the first housing and a second side press-fitting portion press-fitted into the second housing. The power supply terminal has a second side press-fitting portion press-fitted into the second housing and does not have a first side press-fitting portion press-fitted into the first housing.

[0047] Therefore, the separation of the first housing and the second housing is suppressed by the signal terminal. In addition, since the power supply terminal does not have a first side press-fitting portion press-fitted into the first housing, the power supply terminal is easily inserted into the housing in a state where the first housing and the second housing are aligned.

[0048] In addition, since the number of the signal terminals is larger than the number of the power supply terminals, the separation of the first housing and the second housing is suppressed by the larger number of signal terminals.

[0049] That is, in this method, compared with the method in which both the signal terminal and the power supply terminal have a first side press-fitting portion, the insertion of the terminal into the housing becomes easier, and compared with the method in which only a smaller number of power supply terminals have a first side press-fitting portion, the separation of the first housing and the second housing is reliably suppressed.

[0050] The connector according to the twelfth aspect is such that, in any of the first to eleventh aspects, the first housing and the second housing are provided with an anti-separation mechanism, which is configured to include an engaging claw portion and a locking portion, and the first housing and the second housing are prevented from separating in the assembling direction by the engaging claw portion being hooked on the locking portion.

[0051] In this aspect, the first housing and the second housing are provided with an anti-separation mechanism. The anti-separation mechanism is configured to include an engaging claw portion and a locking portion, and the first housing and the second housing are prevented from separating in the assembling direction by the engaging claw portion being hooked on the locking portion.

[0052] Therefore, the first housing and the second housing themselves prevent the first housing and the second housing from separating in the assembling direction.

[0053] In addition, preventing the first housing and the second housing from separating in the assembling direction can also be achieved by combining the anti-separation mechanism of this aspect with other devices. That is, this aspect does not exclude connectors that are provided with other devices for preventing the first housing and the second housing from separating in the assembling direction.

[0054] The connector according to the thirteenth aspect is such that, in the twelfth aspect, a plurality of terminals are provided, and the plurality of terminals include a plurality of signal terminals and a plurality of power supply terminals. The plurality of power supply terminals include one or more one-side power supply terminals arranged on one side in the pitch direction of the signal terminals with respect to the plurality of signal terminals and one or more the other-side power supply terminals arranged on the other side in the pitch direction with respect to the plurality of signal terminals, and the anti-separation mechanism includes a one-side anti-separation mechanism formed between the plurality of signal terminals and the one or more one-side power supply terminals and a the other-side anti-separation mechanism formed between the plurality of signal terminals and the one or more the other-side power supply terminals.

[0055] In this aspect, a plurality of terminals are provided. The plurality of terminals include a plurality of signal terminals and a plurality of power supply terminals. The plurality of power supply terminals include one or more one-side power supply terminals arranged on one side in the pitch direction of the signal terminals with respect to the plurality of signal terminals and one or more the other-side power supply terminals arranged on the other side in the pitch direction with respect to the plurality of signal terminals.

[0056] Moreover, the anti-separation mechanism includes a one-side anti-separation mechanism formed between the plurality of signal terminals and the one or more one-side power supply terminals and a the other-side anti-separation mechanism formed between the plurality of signal terminals and the one or more the other-side power supply terminals.

[0057] Therefore, it is possible to provide a connector that is small in the direction perpendicular to the pitch direction of the signal terminals.

[0058] The connector according to the fourteenth mode is such that, in any of the first to thirteenth modes, the first housing and the second housing are provided with a displacement restricting mechanism, which is configured to include a convex portion and a concave portion, and the relative displacement in a direction orthogonal to the assembling direction of the first housing and the second housing is restricted by inserting the convex portion into the concave portion.

[0059] In this mode, the first housing and the second housing are provided with a displacement restricting mechanism. The displacement restricting mechanism is configured to include a convex portion and a concave portion, and the relative displacement in a direction orthogonal to the assembling direction of the first housing and the second housing is restricted by inserting the convex portion into the concave portion.

[0060] Therefore, the relative displacement in a direction orthogonal to the assembling direction of the first housing and the second housing is prevented by the first housing and the second housing themselves.

[0061] In addition, the prevention of the relative displacement in a direction orthogonal to the assembling direction of the first housing and the second housing can also be achieved by combining the displacement restricting mechanism of this mode with other devices. That is, this mode does not exclude a connector having other devices for preventing the relative displacement in a direction orthogonal to the assembling direction of the first housing and the second housing.

[0062] The connector according to the fifteenth mode is such that, in the fourteenth mode, a plurality of terminals are provided, and the plurality of terminals include a plurality of one - side terminals arranged in the pitch direction on one side in the inter - column direction and a plurality of the other - side terminals arranged in the pitch direction on the other side in the inter - column direction. The first housing has a protruding wall that protrudes in the reverse fitting direction and extends in the pitch direction. A plurality of grooves for holding the plurality of one - side terminals are formed on the wall surface on one side in the inter - column direction of the protruding wall, and a plurality of grooves for holding the plurality of the other - side terminals are formed on the wall surface on the other side in the inter - column direction of the protruding wall. The convex portion of the displacement restricting mechanism is formed on the first housing, and the concave portion of the displacement restricting mechanism is formed on the second housing. A plurality of the concave portions are provided, and the plurality of the concave portions are composed of one or more one - side concave portions formed on one side in the inter - column direction with respect to the second - side holding portion and one or more the other - side concave portions formed on the other side in the inter - column direction with respect to the second - side holding portion.

[0063] In this mode, a plurality of grooves for holding a plurality of terminals are formed on the wall surfaces on both sides in the inter - column direction of the protruding wall. In such a connector, a space for arranging a part of a connection object such as a mating connector is formed outside the protruding wall in the inter - column direction.

[0064] Moreover, in this mode, the displacement restricting mechanism is formed using the portion on the fitting - direction side as compared with this space. Thus, it is possible to provide a displacement restricting mechanism and also make the connector small - sized.

[0065] Advantages of the Invention

[0066] According to the present disclosure, in a connector including a terminal and a housing into which the terminal is inserted, it is possible to increase the design freedom of the holding portion that holds the terminal, and it is easy to adjust connector characteristics such as impedance.

[0091] Hereinafter, embodiments of the present disclosure will be described.

[0092] The arrow X shown in each figure indicates the front of the connector, the arrow Y indicates one side in the width direction of the connector, and the arrow Z indicates the upper side of the connector. In addition, the terms indicating these directions are defined for ease of explanation and do not limit the posture in the state where the connector is used.

[0093] In addition, the +X direction is referred to as the inter-column direction side (of the signal terminal 10), the +Y direction is referred to as the pitch direction side, the -Z direction is referred to as the fitting direction, and the +Z direction is referred to as the anti-fitting direction.

[0094] In addition, the ±Z direction is referred to as the assembly direction (of the fitting housing 30 and the mounting housing 40).

[0095] In Figures 1 to 10 is shown a connector 100 according to the present embodiment.

[0096] The connector 100 is a connector for connecting substrates arranged in parallel with each other.

[0097] Specifically, the connector 100 is mounted on one side substrate 91, a mating-side connector (not shown) is mounted on the other side substrate (not shown), the connector 100 is fitted and connected to the mating-side connector, and the one side substrate 91 and the other side substrate (not shown) are electrically connected. The connector 100 is configured such that the mating-side connector can be fitted and connected from above.

[0098] The connector 100 is not a so-called movable (floating) connector.

[0099] Specifically, the connector 100 includes a fitting housing 30 and a mounting housing 40, and the fitting housing 30 and the mounting housing 40 are not provided for relative displacement of each other.

[0100] However, the above description does not exclude from the scope of the present disclosure a connector 100 in which the fitting housing 30 and the mounting housing 40 are slightly relatively displaceable. In fact, the fitting housing 30 and the mounting housing 40 of the connector 100 according to the present embodiment can be slightly relatively displaced.

[0101] As Figure 10 and the like show, the connector 100 includes a plurality of terminals 10, 20 and housings 30, 40 that hold the plurality of terminals 10, 20. The terminals 10, 20 are formed of a material through which current passes, such as metal. The housings 30, 40 are formed of an insulating material such as synthetic resin.

[0102] The plurality of terminals 10, 20 are composed of a plurality of signal terminals 10 and a plurality of power supply terminals 20.

[0103] The plurality of signal terminals 10 are composed of a plurality of one-side signal terminals 10A on the inter-column direction side and a plurality of the other-side signal terminals 10B on the other side of the inter-column direction.

[0104] Although the one-side signal terminal 10A and the other-side signal terminal 10B have the same structure as each other, they are arranged in a relative posture in the inter-column direction (refer to Figure 17)。The plurality of one-side signal terminals 10A have the same structure and the same posture as each other, and are arranged at the same intervals in the pitch direction. The plurality of the other-side signal terminals 10B have the same structure and the same posture as each other, and are arranged at the same intervals in the pitch direction.

[0105] When there is no particular distinction between the one-side signal terminals 10A and the other-side signal terminals 10B, they are simply referred to as signal terminals 10.

[0106] As shown in 10, the plurality of power terminals 20 are composed of a pair of one-side power terminals 20A on one side in the pitch direction and a pair of the other-side power terminals 20B on the other side in the pitch direction.

[0107] The one-side power terminals 20A are arranged on one side in the pitch direction with respect to the region where the plurality of signal terminals 10 are arranged, and the other-side power terminals 20B are arranged on the other side in the pitch direction with respect to the region where the plurality of signal terminals 10 are arranged. The pair of one-side power terminals 20A are symmetrically structured in the inter-column direction, and the pair of the other-side power terminals 20B are also symmetrically structured in the inter-column direction.

[0108] When there is no particular distinction between the one-side power terminals 20A and the other-side power terminals 20B, they are simply referred to as power terminals 20.

[0109] (Detailed description of the signal terminal 10)

[0110] As Figure 7 、 Figure 17 shown, the signal terminal 10 has an insertion portion 11 inserted into the housings 30 and 40 and a non-insertion portion 12 not inserted into the housings 30 and 40.

[0111] The insertion portion 11 linearly extends in the up-and-down direction, which is the direction of inserting into the housings 30 and 40 (referred to as the "insertion direction"). The insertion portion 11 is inserted into the housings 30 and 40 from below upward. The plate width direction of the insertion portion 11 faces the pitch direction.

[0112] The non-insertion portion 12 is connected to the lower side of the insertion portion 11 and extends from the lower end of the insertion portion 11 toward the outside in the inter-column direction.

[0113] The signal terminal 10 has a substrate fixing portion 124 fixed to the substrate 91 by welding or the like. The substrate fixing portion 124 linearly extends in the inter-column direction. The substrate fixing portion 124 is formed as a part of the non-insertion portion 12.

[0114] As Figure 7As shown, the signal terminal 10 has a fitting-side held portion 13, 14 held by the fitting housing 30 and a mounting-side held portion 15 held by the mounting housing 40. In addition, in this specification, "holding" of the housing with respect to a part of the terminal means restricting movement of a part of the terminal in two or more directions by abutting or approaching from two or more directions including two directions opposite to each other with respect to a part of the terminal.

[0115] The fitting-side held portions 13, 14 have an exposed portion 13 received in a signal terminal holding groove 36 (see Figure 11 , Figure 13 ) extending in the vertical direction formed in the fitting housing 30 and an surrounded portion 14 received in a signal terminal holding hole 37 extending in the vertical direction formed in the fitting housing 30. The exposed portion 13 is in a state of abutting or approaching the fitting housing 30 from three directions (inside the column direction and both sides in the pitch direction) other than the outside in the column direction, and the surrounded portion 14 is in a state of abutting or approaching the fitting housing 30 from four directions in the pitch direction and the column direction.

[0116] The mounting-side held portion 15 only has an surrounded portion 15 received in a signal terminal holding hole 41 (see Figure 13 ) extending in the vertical direction formed in the mounting housing 40. The mounting-side held portion 15 (surrounded portion 15) is in a state of abutting or approaching the mounting housing 40 from four directions in the pitch direction and the column direction.

[0117] The fitting-side held portions 13, 14 and the mounting-side held portion 15 are all formed as a part of an insertion portion 11 extending linearly in the vertical direction (insertion direction).

[0118] Hereinafter, when not particularly distinguishing between the fitting-side held portions 13, 14 and the mounting-side held portion 15, they are only referred to as held portions 13, 14, 15.

[0119] As Figure 17 shown, the signal terminal 10 has a conduction contact portion 131 for conduction contact with the terminal of the mating-side connector. The conduction contact portion 131 is formed as a part of the exposed portion 13 of the fitting-side held portions 13, 14.

[0120] As Figure 9 , Figure 17 shown, the signal terminal 10 has a mounting-side press-in portion 151 press-fitted into the mounting housing 40. In the mounting-side press-in portion 151, locking protrusions are formed on both sides in the pitch direction, which are both sides in the plate width direction thereof. A plurality (two) of mounting-side press-in portions 151 are formed. All the plurality of mounting-side press-in portions 151 are formed on the lower side compared with the vertical center of the mounting-side held portion 15.

[0121] The signal terminal 10 has a fitting-side press-fitting portion 141 that is press-fitted into the housing 30. In the fitting-side press-fitting portion 141, locking projections are formed on both sides in the spacing direction, which are both sides in the plate width direction thereof. The fitting-side press-fitting portion 141 is formed as a part of the surrounded portion 14 of the fitting-side holding portions 13 and 14.

[0122] As Figure 7 shown, the non-insertion portion 12 of the signal terminal 10 has a bent portion 121, a first horizontal portion 122, an inclined portion 123, and a second horizontal portion 124.

[0123] The bent portion 121 is a portion where the lower side of the insertion portion 11 is bent approximately 90 degrees toward the outside in the inter-column direction, and connects the insertion portion 11 and the first horizontal portion 122.

[0124] The first horizontal portion 122 extends toward the outside in the inter-column direction at a position that is spaced upward from the substrate 91.

[0125] The inclined portion 123 is a portion that obliquely connects the first horizontal portion 122 and the second horizontal portion 124, and extends obliquely downward from the first horizontal portion 122 toward the second horizontal portion 124 and toward the outside and downward in the inter-column direction.

[0126] The second horizontal portion 124 is a portion that extends linearly toward the outside in the inter-column direction from the inclined portion 123 and is arranged along the surface of the substrate 91. The second horizontal portion 124 functions as a substrate fixing portion 124.

[0127] As Figure 17 shown, the signal terminal 10 has a wide-width portion 16 and a narrow-width portion 17 having a size smaller than that of the wide-width portion 16. The narrow-width portion 17 is formed below the wide-width portion 16 and is connected to the wide-width portion 16 via a width-changing portion 18 with a changing width dimension. The wide-width portion 16 has the same plate width along the up-down direction, which is the terminal extending direction, and the narrow-width portion 17 also has the same plate width along the terminal extending direction. The width-changing portion 18 is formed such that the plate width gradually increases from the narrow-width portion 17 toward the wide-width portion 16. In a state where the connector 100 and the mating-side connector are fitted to the fitting boundary (a state where they are closest to each other in the fitting direction), the contact position between the signal terminal 10 and the signal terminal of the mating-side connector becomes the lower part of the wide-width portion 16 or the width-changing portion 18.

[0128] By forming the narrow-width portion 17, the impedance is increased, and the conduction contact portion with the connection object is ensured to be the wider wide-width portion 16 or width-changing portion 18 to ensure connection reliability.

[0129] The signal terminal 10 has a front end portion 19. The front end portion 19 is formed by connecting to the wide portion 16 above the wide portion 16. In the front end portion 19, as it advances in the direction away from the wide portion 16 (upward), its plate width and plate thickness gradually decrease.

[0130] As Figure 7 , Figure 17 shown, the signal terminal 10 has a weld 152 formed as part of the mounting side holding portion 15. The weld 152 is formed so that the central portion in the plate width direction of the mounting side holding portion 15 bulges outward in the inter-column direction. The weld 152 extends in the vertical direction. The position where the weld 152 is formed in the mounting side holding portion 15 is the position that coincides with the lower mounting side press-fitting portion 151 among the plurality of (two) mounting side press-fitting portions 151 in the vertical direction (insertion direction). Through the weld 152, the mounting side holding portion 15 can be easily arranged at a position closer to the inner side in the inter-column direction in the signal terminal holding hole 41 of the mounting housing 40.

[0131] As Figure 17 shown, the signal terminal 10 has a pressing portion 125 for inserting the signal terminal 10 into the housings 30 and 40. The pressing portion 125 is formed directly above the bent portion 121 of the non-insertion portion 12, and the plate width expands. When the signal terminal 10 is inserted into the housings 30 and 40, the pressing portion 125 presses upward.

[0132] (Detailed description of the power terminal 20)

[0133] As Figure 9 , Figure 18 shown, the power terminal 20 has an insertion portion 21 that extends in the vertical direction and is inserted into the housings 30 and 40, and a non-insertion portion 22 that is not inserted into the housings 30 and 40. The insertion portion 21 has its plate width direction facing the inter-column direction. The non-insertion portion 22 is connected to the lower side of the insertion portion 21.

[0134] As Figure 8 , Figure 18 shown, the insertion portion 21 has a narrow portion 23 that constitutes its upper part and a wide portion 24 that constitutes its lower part.

[0135] As Figure 8 , Figure 9 shown, the insertion portion 21 has a fitting side holding portion 25 held by the fitting housing 30 and a mounting side holding portion 26 held by the mounting housing 40.

[0136] A part of the upper side of the narrow portion 23 becomes the fitting side holding portion 25, and the whole of the wide portion 24 and a part of the lower side of the narrow portion 23 become the mounting side holding portion 26.

[0137] As Figure 8 ,Figure 18 As shown, the power supply terminal 20 has a locking projection 241 for press-fitting and mounting on the housing 40. The locking projection 241 is formed on the wide-width portion 24. The locking projection 241 is formed only on one side (outside the inter-column direction) in the plate width direction. A plurality (three) of locking projections 241 are formed in the vertical direction (insertion direction). The uppermost locking projection 241 among the plurality of locking projections 241 is formed above the center in the vertical direction of the mounting-side held portion 26, and the lowermost locking projection 241 is formed below the center in the vertical direction of the mounting-side held portion 26.

[0138] On the other hand, the power supply terminal 20 does not have a locking projection for press-fitting and engaging with the housing 30.

[0139] As Figure 18 shown, the non-insertion portion 22 has a bent portion 221, a first horizontal portion 222, an inclined portion 223, and a second horizontal portion 224.

[0140] The bent portion 221 is a portion where the lower side of the insertion portion 21 is bent approximately 90 degrees toward the outside in the pitch direction, and the insertion portion 21 is connected to the first horizontal portion 222.

[0141] The first horizontal portion 222 is disposed at a position upward and away from the substrate 91, with the plate thickness direction facing the vertical direction. The first horizontal portion 222 is formed outside the pitch direction with respect to the insertion portion 11.

[0142] The inclined portion 223 is located outside the inter-column direction with respect to the first horizontal portion 222. The inclined portion 223 connects the second horizontal portion 224 and the first horizontal portion 222 in an inclined manner.

[0143] The second horizontal portion 224 has the plate thickness direction facing the vertical direction and is formed outside the inter-column direction with respect to the inclined portion 223. The second horizontal portion 224 functions as a substrate fixing portion 224 fixed to the substrate by soldering. The second horizontal portion 224 is composed of a portion located outside the inter-column direction of the inclined portion 223 and a portion that expands inward in the pitch direction with respect to this portion.

[0144] As Figure 8 shown, as the lower end of the insertion portion 21, a pair of abutting surfaces 211 are formed on both sides in the plate width direction (inter-column direction) with respect to the portion connected to the non-insertion portion 22. When the power supply terminal 20 is inserted into the housings 30 and 40 from below upward, a jig or the like is brought into contact with the pair of abutting surfaces 211 and pressed upward. The non-insertion portion 22 is connected to a position closer to the center in the inter-column direction of the connector with respect to the center in the plate width direction of the insertion portion 11 (the wide-width portion 24).

[0145] The narrow-width portion 23 is connected to the wide-width portion 24 at a position closer to the center in the direction between connector rows than the center in the plate width direction with respect to the wide-width portion 24. More specifically, the narrow-width portion 23 extends with the same plate width in the vertical direction. One end of the narrow-width portion 23 on the outer side in the direction between rows in the plate width direction is located on the inner side in the direction between connector rows compared to the center of the figure of the wide-width portion 24 viewed from the plate thickness direction (the center of the figure viewed from the same direction as Figure 8 the same direction).

[0146] 《Housings 30 and 40》

[0147] As Figures 11 to 16 shown, the housings 30 and 40 are composed of a fitting housing 30 as the "first housing" and a mounting housing 40 as the "second housing".

[0148] 《Fitting Housing 30 (First Housing)》

[0149] The fitting housing 30 forms the upper part of the housings 30 and 40.

[0150] As Figure 16 shown, the fitting housing 30 is composed of a center portion 30Y1 in the pitch direction forming the center in the pitch direction of the fitting housing 30 and a pair of outer portions 30Y2 in the pitch direction forming the outer portions in the pitch direction of the fitting housing 30.

[0151] In addition, as Figure 14 shown, the fitting housing 30 is composed of a center portion 30X1 in the direction between rows forming the center in the direction between rows of the fitting housing 30 and a pair of outer portions 30X2 in the direction between rows forming the outer portions in the direction between rows of the fitting housing 30.

[0152] As Figure 11 , Figure 12 , Figure 13 shown, the fitting housing 30 has a bottom wall 31, a peripheral wall 32 erected upward from the periphery of the bottom wall 31, a protruding wall 33 protruding upward from the center of the bottom wall 31, a plurality of (six) positioning convex portions 34 protruding downward from the bottom wall 31, and a pair of protruding claw portions 35 protruding downward from the bottom wall 31.

[0153] In the fitting housing 30, a fitting recess 30U in which a part of the mating-side connector is arranged when the connector 100 is connected to the mating-side connector is formed. The fitting recess 30U is a space above the bottom wall 31 of the fitting housing 30 and is a space surrounded by the peripheral wall 32.

[0154] (Signal Terminal Holding Groove 36)

[0155] The protruding wall 33 is erected upward from the bottom surface of the fitting recess 30U, from the center. The protruding wall 33 is a wall extending in the pitch direction, and has a pair of wall surfaces 33A and 33B on both sides in the wall thickness direction (inter-column direction). On the pair of wall surfaces 33A and 33B of the protruding wall 33, a plurality of signal terminal holding grooves 36 for holding the signal terminals 10 are formed in the pitch direction. The protruding wall 33 is formed at the pitch direction central portion 30Y1 and the inter-column direction central portion 30X1 of the fitting housing 30.

[0156] The signal terminal holding groove 36 corresponds to the "first side holding portion".

[0157] (Signal terminal holding hole 37)

[0158] A signal terminal holding hole 37 penetrating the bottom wall 31 in the vertical direction is formed in the bottom wall 31 of the fitting housing 30. The signal terminal holding hole 37 is continuously formed below the signal terminal holding groove 36.

[0159] The signal terminal holding hole 37 corresponds to the "first side surrounding portion" of the "first side holding portion".

[0160] When not particularly distinguishing between the signal terminal holding groove 36 and the signal terminal holding hole 37, they are referred to as signal terminal holding portions 36, 37. The signal terminal holding portions 36, 37 are formed at the pitch direction central portion 30Y1 and the inter-column direction central portion 30X1 of the fitting housing 30.

[0161] As Figure 11 shown, the peripheral wall 32 of the fitting housing 30 is composed of a pair of pitch direction walls 32Y extending in the inter-column direction on both sides in the pitch direction and a pair of inter-column direction walls 32X extending in the pitch direction on both sides in the inter-column direction.

[0162] The pitch direction walls 32Y are formed at the same height over the entire range from end to end in the inter-column direction of the fitting housing 30. On the other hand, the inter-column direction walls 32X are walls having a height lower than that of the pitch direction walls 32Y, and are formed only in the range between one pitch direction wall 32Y and the other pitch direction wall 32Y within the entire range from end to end in the pitch direction of the fitting housing 30. The height of the pitch direction walls 32Y is higher than that of the protruding wall 33, and the height of the inter-column direction walls 32X is lower than that of the protruding wall 33.

[0163] (Power terminal holding groove 38)

[0164] As Figure 9 、 Figure 11 shown, power terminal holding grooves 38 extending in the vertical direction are formed on the wall surfaces on the inner side in the pitch direction of the pitch direction walls 32Y. Two power terminal holding grooves 38 are formed on each of the pair of pitch direction walls 32Y, for a total of four.

[0165] The power terminal holding groove 38 corresponds to the "first side holding portion".

[0166] (Power terminal holding hole 39)

[0167] As Figure 9 shown, on the fitting housing 30, a power terminal holding hole 39 extending in the vertical direction is formed. The power terminal holding hole 39 is continuously formed below the power terminal holding groove 38 and is continuous with the power terminal holding groove 38.

[0168] The power terminal holding hole 39 corresponds to the "first side surrounding portion" of the "first side holding portion".

[0169] When there is no special distinction between the power terminal holding groove 38 and the power terminal holding hole 39, they are referred to as the power terminal holding portions 38, 39. The power terminal holding portions 38, 39 are formed in the outer portion 30Y2 in the pitch direction and the central portion 30X1 in the inter-column direction of the fitting housing 30.

[0170] As Figure 15 shown, the lower surface 303 of the central portion 30Y1 in the pitch direction of the fitting housing 30 is located above the lower surface 304 of the outer portion 30Y2 in the pitch direction and does not contact the upper surface of the mounting housing 40.

[0171] 《Mounting housing 40 (second housing)》

[0172] The mounting housing 40 constitutes the lower part of the housings 30, 40.

[0173] The mounting housing 40 has a substantially rectangular parallelepiped shape.

[0174] More specifically, the mounting housing 40 has a rectangular shape in a plan view with the pitch direction as the long side direction and the inter-column direction as the short side direction. The mounting housing 40 is provided with a shape that is longer in the longitudinal direction, and the vertical dimension of the mounting housing 40 is larger than the dimension in the short side direction (inter-column direction) of the mounting housing 40.

[0175] As Figure 16 shown, the mounting housing 40 is composed of a central portion 40Y1 in the pitch direction constituting the central part in this pitch direction and a pair of outer portions 40Y2 in the pitch direction constituting the outer part in this pitch direction.

[0176] In addition, as Figure 14 shown, the mounting housing 40 is composed of a central portion 40X1 in the inter-column direction constituting the central part in this inter-column direction and a pair of outer portions 40X2 in the inter-column direction constituting the outer part in this inter-column direction.

[0177] (Signal terminal holding hole 41)

[0178] As Figure 11 、 Figure 13 shown, signal terminal holding holes 41 extending in the vertical direction through the mounting housing 40 are formed in the mounting housing 40.

[0179] The signal terminal holding holes 41 extend linearly in the vertical direction. A plurality of signal terminal holding holes 41 are formed corresponding to the plurality of signal terminals 10. The plurality of signal terminal holding holes 41 are formed in the central portion 40Y1 in the pitch direction and the central portion 40X1 in the inter-column direction of the mounting housing 40.

[0180] The signal terminal holding holes 41 correspond to the "second side surrounding portion" of the "second side holding portion".

[0181] The plurality of signal terminal holding holes 41 are composed of a plurality of signal terminal holding holes 41 on one side in the inter-column direction and a plurality of signal terminal holding holes 41 on the other side in the inter-column direction.

[0182] (Power terminal holding hole 44)

[0183] Power terminal holding holes 44 extending in the vertical direction through the mounting housing 40 are formed in the mounting housing 40.

[0184] A plurality of power terminal holding holes 44 are formed corresponding to the plurality of power terminals 20.

[0185] The power terminal holding holes 44 correspond to the "surrounding portion" of the "second side holding portion" of the present disclosure.

[0186] The plurality of power terminal holding holes 44 are composed of a pair of power terminal holding holes 44 on one side in the pitch direction and a pair of power terminal holding holes 44 on the other side in the pitch direction. The pair of power terminal holding holes 44 on one side in the pitch direction and the pair of power terminal holding holes 44 on the other side in the pitch direction are respectively formed in the outer portion 40Y2 in the pitch direction of the mounting housing 40. The power terminal holding holes 44 are formed not only in the central portion 40X1 in the inter-column direction of the mounting housing 40 but also in the outer portion 40X2 in the inter-column direction (see Figure 8 ).

[0187] As Figure 8 shown, the power terminal holding hole 44 has a wide-width holding portion 44L for holding the wide-width portion 24 of the insertion portion 21 of the power terminal 20 and a narrow-width holding portion 44U for holding the lower portion of the narrow-width portion 23 of the insertion portion 21 of the power terminal 20. The width of the wide-width holding portion 44L in the inter-column direction is larger than the width of the narrow-width holding portion 44U in the inter-column direction.

[0188] As Figure 11 、 Figure 13As shown, a central hollow portion 49 is formed between a plurality of signal terminal holding holes 41 on one side in the inter-column direction and a plurality of signal terminal holding holes 41 on the other side in the inter-column direction.

[0189] The central hollow portion 49 is a portion where the resin of the mounting case 40 is removed, and is a space opened on the upper surface of the mounting case 40. The central hollow portion 49 is formed at the central portion 40Y1 in the pitch direction and the central portion 40X1 in the inter-column direction of the mounting case 40 in the same manner as the plurality of signal terminal holding holes 41. A plurality of (three in the figure) central hollow portions 49 are arranged and formed in the pitch direction. Each of the plurality of central hollow portions 49 forms a space in a substantially rectangular parallelepiped shape.

[0190] (XY-direction displacement restricting mechanisms 34, 47)

[0191] The fitting case 30 and the mounting case 40 have XY-direction displacement restricting mechanisms 34, 47 that restrict the relative displacement in the XY direction between each other by mutual contact within a certain range.

[0192] The XY-direction displacement restricting mechanisms 34, 47 are configured to include a positioning convex portion 34 of the fitting case 30 and a positioning concave portion 47 of the mounting case 40. By inserting the positioning convex portion 34 of the fitting case 30 into the inside of the positioning concave portion 47 of the fitting case 30, the relative displacement in the XY direction between the fitting case 30 and the mounting case 40 is restricted within a certain range.

[0193] Hereinafter, a specific description will be given.

[0194] As Figure 11 shown, a plurality of positioning concave portions 47 are formed on the mounting case 40.

[0195] The positioning concave portion 47 is a portion recessed downward from the upper surface of the mounting case 40. The space formed by the positioning concave portion 47 has a substantially rectangular parallelepiped shape with each side facing the XYZ directions. An inclined surface for guiding the positioning convex portion 34 into the inside of the positioning concave portion 47 is formed at the opening edge of the positioning concave portion 47.

[0196] As Figure 11 、 Figure 12 shown, a plurality of positioning convex portions 34 are formed on the fitting case 30.

[0197] The positioning convex portion 34 is a portion protruding downward from the lower surface of the fitting case 30. The positioning convex portion 34 has a substantially rectangular parallelepiped shape with each side facing the XYZ directions. An inclined surface for guiding into the inside of the positioning concave portion 47 is formed at the lower end portion (front end portion) of the positioning convex portion 34.

[0198] As Figure 12 、 Figure 13As shown, a base portion 34N with a gradually increasing size in the XY direction toward the base end side is formed at the upper end portion (base end portion) of the positioning convex portion 34. In the base portion 34N, the size expands on both sides in the pitch direction and outside in the inter-column direction, and does not expand inside in the inter-column direction.

[0199] The multiple positioning concave portions 47 and the multiple positioning convex portions 34 that constitute the XY direction displacement restricting mechanism 34, 47 are composed of the multiple positioning concave portions 47 and the multiple positioning convex portions 34 on one side in the inter-column direction (hereinafter referred to as the "one-side displacement restricting mechanism") and the multiple positioning concave portions 47 and the multiple positioning convex portions 34 on the other side in the inter-column direction (hereinafter referred to as the "other-side displacement restricting mechanism"). In a plan view, a plurality of signal terminal holding portions 36, 37, 41 for holding the signal terminals 10 are formed between the one-side displacement restricting mechanism and the other-side displacement restricting mechanism.

[0200] The XY direction displacement restricting mechanism 34, 47 is configured such that in a state where the multiple positioning convex portion connectors are respectively inserted into the multiple positioning concave portions 47, the fitting housing 30 can be displaced within a certain range in two directions in the XY direction with respect to the mounting housing 40.

[0201] Therefore, it is possible to avoid the situation where the positioning convex portion 34 cannot be inserted into the positioning concave portion 47 due to manufacturing tolerances in resin molding of the mounting housing 40 and the fitting housing 30. Such a configuration is achieved by appropriately designing the mold for forming the mounting housing 40 and the mold for forming the fitting housing 30.

[0202] The fitting housing 30 and the mounting housing 40 are in contact with each other in the up-down direction at a pair of outer portions 30Y2, 40Y2 in the pitch direction, and are not in contact with each other in the up-down direction at the central portion 30Y1, 40Y1 in the pitch direction. With such a configuration, in the case where the mounting housing 40 or the fitting housing 30 is somewhat deformed due to heat or the like, it is difficult for the mounting housing 40 and the fitting housing 30 to come into contact with each other at the central portion 30Y1, 40Y1 in the pitch direction. In addition, when the housing is deformed due to heat or the like, warping is likely to occur in the central portion of the housing. Therefore, assuming that the mounting housing 40 and the fitting housing 30 in the central portion of the housing are in contact with each other and there is concern about deformation due to heat or the like, unexpected forces may be exerted on each other's housings.

[0203] (Z-direction anti-separation mechanism)

[0204] As Figure 15 , Figure 16 shown, the fitting housing 30 and the mounting housing 40 have anti-separation mechanisms 35, 48 for preventing separation in the Z direction (assembly direction).

[0205] The anti-separation mechanisms 35 and 48 are configured to include the engaging recess 48 of the mounting housing 40 and the protruding claw portion 35 of the fitting housing 30. By engaging the protruding claw portion 35 with the engaging recess 48, separation of the fitting housing 30 and the mounting housing 40 is prevented.

[0206] Hereinafter, a specific description will be given.

[0207] As Figure 15 shown, the fitting housing 30 has a pair of protruding claw portions 35. The pair of protruding claw portions 35 is composed of a protruding claw portion 35 on one side in the pitch direction and a protruding claw portion 35 on the other side in the pitch direction. The pair of protruding claw portions 35 are provided with the same structure and are symmetric in the pitch direction. An engaging portion 35K that engages with the engaging portion 48K of the engaging recess 48 is formed on the protruding claw portion 35. The engaging portion 35K is formed on the inner side in the pitch direction of the protruding claw portion 35.

[0208] The mounting housing 40 has a pair of engaging recesses 48. The engaging recess 48 is composed of an engaging recess 48 on one side in the pitch direction and an engaging recess 48 on the other side in the pitch direction.

[0209] An inclined surface 48L for gradually deforming the protruding claw portion 35 during assembly is formed on the engaging recess 48. The inclined surface 48L is formed on the inner side in the pitch direction of the engaging recess 48.

[0210] In addition, an engaging portion 48K for engaging the engaging portion 35K of the protruding claw portion 35 is formed on the engaging recess 48. The engaging portion 48K is formed below the inclined surface 48L.

[0211] When the fitting housing 30 is assembled to the mounting housing 40, the engaging portion 35K of the protruding claw portion 35 straddles the inclined surface 48L of the engaging recess 48, so that the pair of protruding claw portions 35 elastically deform toward the outside in the pitch direction.

[0212] When the engaging portion 35K of the protruding claw portion 35 straddles the inclined surface 48L, the shape of the elastically deformed protruding claw portion 35 returns to its original shape. Then, the engaging portion 35K of the protruding claw portion 35 is disposed below the engaging portion 48K formed on the lower side of the inclined surface 48L of the engaging recess 48 (see Figure 16 ). From this state, it can be seen that even if the fitting housing 30 is moved upward relative to the mounting housing 40, the engaging portion 35K of the protruding claw portion 35 abuts against the engaging portion 48K of the engaging recess 48, preventing separation of the two housings 30 and 40.

[0213] (Cross-sectional structure of the signal terminal holding portion)

[0214] Next, the cross-sectional structures of the signal terminal holding holes 41 of the mounting housing 40, the signal terminal holding holes 37 of the fitting housing 30, and the signal terminal holding grooves 36 will be described.

[0215] In addition, in Figures 19 to 24 in order to easily see the structures of the signal terminal holding portions 36, 37, and 41, illustration is made by omitting a pair of signal terminals 10 on the outermost side in the inter-column direction.

[0216] First, the cross-sectional structure of the signal terminal holding hole 41 of the mounting housing 40 will be described.

[0217] Figure 19 , Figure 20 , Figure 21 are diagrams showing an enlarged view of the signal terminal holding hole 41 of the mounting housing 40, and are cross-sectional perspective views showing the appearance of being cut in a plane orthogonal to the up-down direction (see Figure 14 ).

[0218] Figure 19 represents the lower part 43 of the signal terminal holding hole 41 of the mounting housing 40, Figure 20 represents the boundary portion between the lower part 43 and the upper part 42 of the signal terminal holding hole 41 of the mounting housing 40, Figure 21 represents the upper part 42 of the signal terminal holding hole 41 of the mounting housing 40.

[0219] Since the cross-sectional structure of the signal terminal holding hole 41 of the mounting housing 40 is different, it can be divided into a lower part 43 and an upper part 42. The upper part 42 of the signal terminal holding hole 41 of the mounting housing 40 has a larger hole than the lower part 43. As Figure 20 shown, a step is formed at the boundary between the lower part 43 and the upper part 42 of the signal terminal holding hole 41 of the mounting housing 40.

[0220] As Figure 19 , Figure 20 , Figure 21 shown, both the upper part 42 and the lower part 43 of the signal terminal holding hole 41 of the mounting housing 40 have an inner side surface 41L in the inter-column direction, a pair of side surfaces 41S, and an outer side surface 41U in the inter-column direction.

[0221] The inner side surface 41L in the inter-column direction of the upper part 42 of the signal terminal holding hole 41 is located more inside in the inter-column direction than the inner side surface 41L in the inter-column direction of the lower part 43.

[0222] The side surface 41S on one side in the pitch direction of the upper part 42 of the signal terminal holding hole 41 is located on one side in the pitch direction compared to the side surface 41S on one side in the pitch direction of the lower part 43.

[0223] The side surface 41S on the other side in the inter-column direction of the upper part 42 of the signal terminal holding hole 41 is located on the other side in the pitch direction compared to the side surface 41S on the other side in the pitch direction of the lower part 43.

[0224] The outer side surface 41U in the inter-column direction of the upper part 42 of the signal terminal holding hole 41 is located on the outer side in the inter-column direction compared to the outer side surface 41U in the inter-column direction of the lower part 43.

[0225] The mounting-side held portion 15 of the signal terminal 10 is arranged at a position closer to the inner side in the inter-column direction in the signal terminal holding hole 41. Such a configuration is achieved by forming a weld 152 on the mounting-side held portion 15.

[0226] Therefore, in the lower part 43 of the signal terminal holding hole 41, the signal terminal 10 contacts the inner side surface 41L in the inter-column direction of the signal terminal holding hole 41 (see Figure 19 ). On the other hand, in the upper part 42 of the signal terminal holding hole 41, a gap is left between the inner side surface 41L in the inter-column direction of the signal terminal holding hole 41 and the signal terminal 10 (see Figure 21 ).

[0227] A recess 41R recessed inward in the inter-column direction is formed on the inner side in the inter-column direction of the signal terminal holding hole 41. The position where the recess 41R is formed is set to the middle position in the width direction (spacing direction) of the inner side surface 41L in the inter-column direction. Therefore, due to the recess 41R, the inner side surface 41L in the inter-column direction is separated into one side and the other side in the width direction (spacing direction). The inner side surface 41L on one side separated by the recess 41R and the inner side surface 41L on the other side jointly abut or approach the signal terminal 10 from the inner side in the inter-column direction.

[0228] The recess 41R functions as an enlarging portion for expanding the interval between the signal terminal 10 and the mounting housing 40 in a cross-sectional view orthogonal to the vertical direction (terminal extending direction). By adjusting the shape of the enlarging portion (recess 41R), the impedance of the signal terminal 10 can be adjusted.

[0229] The recess 41R is formed in a groove shape extending in the vertical direction (the extending direction of the signal terminal holding hole 41). The range where the groove-shaped recess 41R is formed is the entire range in the extending direction of the signal terminal holding hole 41 of the mounting housing 40. The cross-sectional shape of the recess 41R is rectangular.

[0230] (Signal terminal holding portions 36, 37 of the fitting housing 30)

[0231] Next, the cross-sectional structure of the signal terminal holding hole 37 and the signal terminal holding groove 36 of the fitting housing 30 will be described.

[0232] Figure 22 、 Figure 23 、 Figure 24 are enlarged views showing the signal terminal holding hole 37 or the signal terminal holding groove 36 of the fitting housing 30. Figure 22 、 Figure 23is a cross-sectional perspective view showing the appearance of a cut in a plane orthogonal to the vertical direction (see Figure 14 ), Figure 24 is a perspective view.

[0233] Figure 22 represents the signal terminal holding hole 37 (the first side surrounding portion), Figure 23 , Figure 24 represents the signal terminal holding groove 36.

[0234] As Figure 22 shown, the signal terminal holding hole 37 has an inner side surface 37L in the inter-column direction, a pair of side surfaces 37S, and an outer side surface 37U in the inter-column direction. The inner side surface 37L in the inter-column direction abuts or approaches the inner side in the inter-column direction of the signal terminal 10, the pair of side surfaces 37S approach the outer side in the pitch direction of the signal terminal 10, and the outer side surface 37U in the inter-column direction approaches the outer side in the inter-column direction of the signal terminal 10.

[0235] A pair of inclined surfaces 37K are formed between the outer side surface 37U in the inter-column direction and the pair of side surfaces 37S. The pair of inclined surfaces 37K contact the held portion 14 of the signal terminal 10. Specifically, the corner portions of the held portion 14 of the signal terminal 10 bite into the pair of inclined surfaces 37K. Through the pair of inclined surfaces 37K, the held portion 14 of the signal terminal 10 is arranged closer to the inner side in the inter-column direction within the signal terminal holding hole 37.

[0236] The surface on the side where the signal terminal 10 is disposed closer within the signal terminal holding hole 37 can be referred to as the "bottom surface", and the surface on the side opposite to the bottom surface can be referred to as the "top surface". The inner side surface 37L in the inter-column direction corresponds to the "bottom surface", and the outer side surface 37U in the inter-column direction corresponds to the "top surface".

[0237] A bottom surface side recess 37R1 is formed on the bottom surface side (the inner side surface 37L side) of the signal terminal holding hole 37. The position where the bottom surface side recess 37R1 is formed is the central position in the pitch direction (width direction) of the inner side surface 37L in the inter-column direction. Thus, through the bottom surface side recess 37R1, the inner side surface 37L in the inter-column direction is separated into one side and the other side in the pitch direction (width direction). The inner side surface 37L on one side separated by the bottom surface side recess 37R1 and the inner side surface 37L on the other side jointly abut or approach the signal terminal 10 from the bottom surface side.

[0238] On the top surface side of the signal terminal holding hole 37 (on the side of the inter-column direction outer surface 37U), a top surface side recess 37R2 is formed. The position where the top surface side recess 37R2 is formed is the central position in the pitch direction (width direction) of the inter-column direction outer surface 37U (top surface). Thus, due to the top surface side recess 37R2, the inter-column direction outer surface 37U is separated into one side and the other side in the pitch direction (width direction). The inter-column direction outer surface 37U on one side separated by the top surface side recess and the inter-column direction outer surface 37U on the other side jointly abut or approach the signal terminal 10 from the top surface side.

[0239] In a cross-section orthogonal to the vertical direction (terminal extending direction), the bottom surface side recess 37R1 and the top surface side recess 37R2 function as an enlarged portion for expanding the interval between the signal terminal 10 and the fitting housing 30. By adjusting the shape of the enlarged portion (the bottom surface side recess 37R1 and the top surface side recess 37R2), the impedance of the signal terminal 10 can be adjusted.

[0240] The cross-sectional shape of the bottom surface side recess 37R1 is rectangular. The cross-sectional shape of the top surface side recess 37R2 is rectangular. The pitch direction dimension (width of the recess) of the top surface side recess 37R2 is larger than the pitch direction dimension (width of the recess) of the bottom surface side recess 37R1. The inter-column direction dimension (depth of the recess) of the top surface side recess 37R2 is larger than the inter-column direction dimension (depth of the recess) of the top surface side recess 37R2.

[0241] The bottom surface side recess 37R1 and the top surface side recess 37R2 are formed in a groove shape extending in the vertical direction. The range where the groove-shaped bottom surface side recess 37R1 and top surface side recess 37R2 are formed is the entire range in the extending direction of the signal terminal holding hole 37 of the fitting housing 30.

[0242] (Retention groove)

[0243] Next, the signal terminal holding groove 36 formed in the upper part of the signal terminal holding portions 36 and 37 constituting the fitting housing 30 will be described.

[0244] Figure 23 、 Figure 24 The signal terminal holding groove 36 of,

[0245] The signal terminal holding groove 36 is configured to include an inner side surface 36L in the inter-column direction that contacts or approaches the inside of the signal terminal 10 in the inter-column direction, and a pair of side surfaces 36S that contact or approach both sides of the signal terminal 10 in the pitch direction. By arranging the signal terminal 10 in the signal terminal holding groove 36, the fitting housing 30 contacts or approaches the signal terminal 10 from three directions: the inner side in the inter-column direction and both sides in the pitch direction.

[0246] A recess 36R is formed on the bottom surface side (inner side surface 36L side in the inter-column direction) of the signal terminal holding groove 36. Due to the recess 36R, the space on the bottom surface side expands with respect to the signal terminal 10. By adjusting the shape and size of the recess 36R, the impedance of the portion of the signal terminal holding groove 36 that houses the signal terminal can be adjusted.

[0247] The position where the recess 36R is formed is the central position in the pitch direction (width direction) of the inner side surface 36L in the inter-column direction. Thus, due to the recess 36R, the inner side surface 36L in the inter-column direction is separated into one side and the other side in the pitch direction (width direction). The inner side surface 36L on one side and the inner side surface 36L on the other side separated by the recess on the bottom surface side contact or approach the signal terminal 10 from the bottom surface side together.

[0248] The recess 36R is formed in a groove shape extending in the vertical direction (the extending direction of the signal terminal holding groove 36). The cross-sectional shape of the recess 36R (the cross-sectional shape orthogonal to the extending direction) is rectangular.

[0249] The recess 36R of the signal terminal holding groove 36 is connected to the recess 37R1 on the bottom surface side of the signal terminal holding hole 37 in the vertical direction. More specifically, the recess 36R of the signal terminal holding groove 36 and the recess 37R1 on the bottom surface side of the signal terminal holding hole 37 have the same cross-sectional shape and are directly continuous in the vertical direction.

[0250] As Figure 24 shown, the upper end (front end) of the recess 36R of the signal terminal holding groove 36 does not reach the upper end (front end) of the signal terminal holding groove 36. Thus, the recess 36R of the signal terminal holding groove 36 is covered by the signal terminal 10, preventing the recess 36R from being exposed. When the recess 41R is exposed on the upper side (front end side) compared to the upper end (front end) of the signal terminal 10, problems may occur such as the mating side connector or other connection objects getting stuck in the recess 41R, or foreign objects entering the recess 41R. In contrast, if the front end side portion of the recess 41R is covered by the terminal, such problems are prevented.

[0251] In addition, the upper end (front end) of the recess 41R does not reach the position covered by the front end portion 19 of the signal terminal 10 and is covered by the wide portion 16 of the signal terminal 10. Thus, more precisely, foreign objects entering the recess 41R and the like are prevented.

[0252] <Effect>

[0253] Next, the effect of this embodiment will be described.

[0254] In this embodiment, the connector 100 includes terminals (signal terminal 10, power terminal 20) and housings 30 and 40 into which the terminals are inserted. The housings 30 and 40 are configured to include a first housing (fitting housing 30) and a second housing (mounting housing 40). The first housing has a first-side holding portion (signal terminal holding portions 36 and 37, power terminal holding portions 38 and 39 of the fitting housing 30) that holds a part of the terminals, and the second housing has a second-side holding portion (signal terminal holding portion 41, power terminal holding portion 44 of the mounting housing 40) that holds the other part of the terminals.

[0255] That is, the holding portions for holding the terminals are formed by the first housing (fitting housing 30) and the second housing (mounting housing 40). Therefore, compared with the method of forming all the holding portions for holding the terminals on one housing, the degree of freedom in designing the holding portions is increased due to the nature of housing forming by a mold. When the degree of freedom in designing the holding portions is increased, it is easy to adjust connector characteristics such as impedance.

[0256] In addition, in this embodiment, the first-side holding portion (signal terminal holding portions 36 and 37 of the fitting housing 30) is configured to include a first-side surrounding portion (signal terminal holding hole 37 of the fitting housing 30) that surrounds the terminal (signal terminal 10), and the second-side holding portion (signal terminal holding portion 41 of the mounting housing 40) is configured to include a second-side surrounding portion (signal terminal holding hole 41 of the mounting housing 40) that surrounds the terminal (signal terminal 10). That is, the first-side holding portion and the second-side holding portion are configured to commonly include a surrounding portion that surrounds the terminal.

[0257] Therefore, for example, even when compared with the method in which the first-side holding portion is configured to include a surrounding portion and the second-side holding portion is configured not to include a surrounding portion, an increase in the impedance of the portion of the terminals held by the second housing (mounting housing 40) can be suppressed.

[0258] In addition, in this embodiment, the first-side holding portion (signal terminal holding portions 36 and 37 of the fitting housing 30) and the second-side holding portion (signal terminal holding portion 41 of the mounting housing 40) are located on a straight line.

[0259] Therefore, it is not necessary to form a bent portion between the portion of the terminals (signal terminal 10) held by the first-side holding portion and the portion held by the second-side holding portion.

[0260] In addition, in the present embodiment, the first side surrounding portion (the signal terminal holding hole 37 of the fitting housing 30) and the second side surrounding portion (the signal terminal holding hole 41 of the mounting housing 40) are located on a straight line.

[0261] Therefore, when manufacturing the connector, when aligning the first housing (the fitting housing 30) and the second housing (the mounting housing 40) with each other (refer to Figure 14 ), the first side surrounding portion (the signal terminal holding hole 37 of the fitting housing 30) and the second side surrounding portion (the signal terminal holding hole 41 of the mounting housing 40) are located on a straight line. Therefore, the terminal (the signal terminal 10) can be inserted along this straight line.

[0262] In addition, in the present embodiment, the distance D between the first side surrounding portion (the signal terminal holding hole 37 of the fitting housing 30) and the second side surrounding portion (the signal terminal holding hole 41 of the mounting housing 40) (refer to Figure 7 ) is short (specifically, shorter than the shorter one of the first side surrounding portion (the signal terminal holding hole 37 of the fitting housing 30) and the second side surrounding portion (the signal terminal holding hole 41 of the mounting housing 40)).

[0263] Therefore, the length of the portion of the terminal (the signal terminal 10) located between the first side surrounding portion and the second side surrounding portion, that is, the portion not surrounded by the housings 30 and 40, becomes short. As a result, compared with the case where this length is long, the section where the impedance is likely to increase can be shortened.

[0264] In addition, in the present embodiment, the first housing is the fitting housing 30 that fits with the connection object, and the second housing is the mounting housing 40 disposed between the first housing and the substrate. The terminals (the signal terminals 10 and the power terminals 20) are inserted into the housings 30 and 40 with the anti-fitting direction as the insertion direction.

[0265] Therefore, it is suitable for a connector with a large fitting direction.

[0266] In addition, in the present embodiment, a plurality of terminals (the signal terminals 10) are provided. The plurality of terminals include a plurality of one-side terminals (one-side signal terminals 10A) arranged in the pitch direction on one side in the inter-column direction and a plurality of the other-side terminals (the other-side signal terminals 10B) arranged in the pitch direction on the other side in the inter-column direction. The first housing (the fitting housing 30) has a protruding wall 33 that protrudes in the anti-fitting direction and extends in the pitch direction. A plurality of grooves (signal terminal holding grooves 36) for holding the plurality of one-side terminals are formed on the wall surface 33A on one side in the inter-column direction of the protruding wall 33, and a plurality of grooves (signal terminal holding grooves 36) for holding the plurality of the other-side terminals are formed on the wall surface 33B on the other side in the inter-column direction of the protruding wall 33.

[0267] Therefore, it is suitable for a multi-pole socket connector.

[0268] In addition, in the present embodiment, the first housing is a fitting housing 30 that fits with the object to be connected. The terminal (signal terminal 10) is inserted into the housings 30 and 40 from the second housing side among the first housing or the second housing (mounting housing 40) in the reverse fitting direction as the insertion direction.

[0269] Moreover, one end on the fitting direction side (lower side) of the second side surrounding portion (signal terminal holding hole 41 of the mounting housing 40) is located within a range of 20% (more preferably 15%) on the connector fitting direction side (refer to Figure 14 ).

[0270] Therefore, the portion on the fitting direction side of the terminal (signal terminal 10) can be effectively surrounded by the second surrounding portion. Thus, for example, compared with the connector of Patent Document 1 in which the portion on the fitting direction side (lower portion) of the terminal is exposed, an increase in impedance of the portion on the fitting direction side of the terminal (signal terminal 10) can be suppressed.

[0271] In addition, in the present embodiment, the first housing (fitting housing 30) is a fitting housing 30 that fits with the object to be connected (mating side connector). The terminal (signal terminal 10) is inserted into the housings 30 and 40 from the second housing side among the first housing or the second housing (mounting housing 40) in the reverse fitting direction as the insertion direction. Moreover, the second side holding portion (signal terminal holding portion 41 of the mounting housing 40) is composed only of the second side surrounding portion (signal terminal holding hole 41 of the mounting housing 40) that surrounds the terminal (signal terminal 10).

[0272] Therefore, the portion on the fitting direction side of the terminal can be effectively surrounded by the mounting housing 40. Thus, for example, compared with the connector of Patent Document 1 in which the portion on the fitting direction side (lower portion) of the terminal is exposed, an increase in impedance of the portion on the fitting direction side of the terminal can be suppressed.

[0273] In addition, in the present embodiment, the terminal (signal terminal 10) has a first side press-fitting portion (fitting side press-fitting portion 141) press-fitted into the first housing (fitting housing 30) and a second side press-fitting portion (mounting side press-fitting portion 151) press-fitted into the second housing (mounting housing 40).

[0274] Therefore, separation of the first housing and the second housing is suppressed by the terminal.

[0275] In addition, in the present embodiment, the signal terminal 10 and the power supply terminal 20 are inserted into the second housing side of the first housing (the fitting housing 30) or the second housing (the mounting housing 40) into the housings 30 and 40. The signal terminal 10 has a first side press-fitting portion (fitting side press-fitting portion 141) press-fitted into the first housing and a second side press-fitting portion (mounting side press-fitting portion 151) press-fitted into the second housing. The power supply terminal 20 has a second side press-fitting portion (wide portion 24) press-fitted into the second housing and does not have a first side press-fitting portion press-fitted into the first housing.

[0276] Therefore, the separation of the first housing and the second housing is suppressed by the signal terminal 10. In addition, since the power supply terminal 20 does not have a first side press-fitting portion press-fitted into the first housing (the fitting housing 30), the insertion of the power supply terminal 20 into the housings 30 and 40 is easy in a state where the first housing and the second housing are aligned.

[0277] In addition, since the number of signal terminals 10 is larger than the number of power supply terminals 20, the separation of the first housing and the second housing is suppressed by the larger number of signal terminals 10.

[0278] That is, in the present embodiment, compared with a method in which both the signal terminal 10 and the power supply terminal 20 have a first side press-fitting portion, the insertion of the terminals (the signal terminal 10 and the power supply terminal 20) into the housing becomes easy, and compared with a method in which only the smaller number of power supply terminals 20 have a first side press-fitting portion, the separation suppression of the first housing and the second housing is reliably performed.

[0279] Moreover, in the present embodiment, since the power supply terminal 20 is formed of a material having a larger plate thickness (specifically, a material having a larger plate thickness than the signal terminal 10), the attitude of the power supply terminal 20 is not easily collapsed even if the power supply terminal 20 does not have a first side press-fitting portion (a press-fitting portion into the first housing).

[0280] In addition, in the present embodiment, the first housing (the fitting housing 30) and the second housing (the mounting housing 40) are provided with anti-separation mechanisms 35 and 48. The anti-separation mechanisms 35 and 48 are configured to include engaging claw portions (projecting claw portions 35) and locking portions 48K, and the first housing and the second housing are prevented from separating in the assembling direction by the engaging claw portions being hooked on the locking portions 48K.

[0281] Therefore, the separation of the first housing and the second housing in the assembling direction is prevented by the first housing and the second housing themselves.

[0282] In addition, in the present embodiment, the anti-separation mechanisms 35 and 48 include the one-side anti-separation mechanisms 35 and 48 formed between the plurality of signal terminals 10 and one or more one-side power supply terminals 20A, and the other-side anti-separation mechanisms 35 and 48 formed between the plurality of signal terminals 10 and one or more other-side power supply terminals 20B.

[0283] Therefore, the connector 100 can be made small in the short-side direction of the connector.

[0284] In addition, in the present embodiment, the first housing (the fitting housing 30) and the second housing (the mounting housing 40) are provided with displacement restricting mechanisms (XY-direction displacement restricting mechanisms 34 and 47). The displacement restricting mechanism is configured to include a positioning convex portion 34 and a positioning concave portion 47. By inserting the positioning convex portion 34 into the positioning concave portion 47, the relative displacement of the first housing and the second housing in the direction orthogonal to the assembly direction is restricted.

[0285] Therefore, the relative displacement in the direction orthogonal to the assembly direction of the first housing and the second housing is prevented by the first housing and the second housing themselves.

[0286] In addition, in the present embodiment, a plurality of grooves (signal terminal holding grooves 36) for holding a plurality of terminals (signal terminals 10) are formed on the wall surfaces 33A and 33B on both sides in the inter-column direction of the protruding wall 33. In such a connector, a space (fitting recess 30U) for disposing a part of a connection object such as a mating connector is formed outside the protruding wall 33 in the inter-column direction.

[0287] And, a displacement restricting mechanism (XY-direction displacement restricting mechanisms 34 and 47) is formed using the part on the fitting direction side compared with this space (fitting recess 30U). Thereby, a connector having a displacement restricting mechanism and being small in size can be achieved.

[0288] In addition, in the present embodiment, as Figure 16 shown, the distance in the pitch direction (the pitch direction dimension of the fitting housing 30) of the pair of outer side surfaces 301 in the pitch direction of the fitting housing 30 is set to be the same as the distance in the pitch direction (the pitch direction dimension of the mounting housing 40) of the outer side surfaces 401 in the pitch direction of the mounting housing 40. And, as Figure 14 shown, the distance in the inter-column direction (the inter-column direction dimension of the fitting housing 30) of the pair of outer side surfaces 302 in the inter-column direction of the fitting housing 30 is set to be the same as the distance in the inter-column direction (the inter-column direction dimension of the mounting housing 40) of the outer side surfaces 402 in the inter-column direction of the mounting housing 40.

[0289] Therefore, by disposing the fitting housing 30 and the mounting housing 40 inside a frame-shaped jig (not shown) that surrounds the fitting housing 30 and the mounting housing 40 in the XY directions, it becomes easy to align the positions of the fitting housing 30 and the mounting housing 40 in the XY directions. In this state, the terminals 10 and 20 can be inserted.

[0290] [Supplementary Explanation of the Above Embodiment]

[0291] In addition, in the above embodiment, the first side holding portion and the second side holding portion jointly include an enclosing portion, but one or both of the first side holding portion and the second side holding portion may not include an enclosing portion. Even in such a case, by forming the holding portion for holding the terminals by dividing it into a first housing and a second housing, the design freedom of the holding portion can be increased, and it becomes easy to adjust the connector characteristics.

[0292] In addition, in the above embodiment, the holding grooves and the holding holes that abut or approach from three directions or four directions including two directions (both sides in the plate width direction of the terminals) where a part of the terminals face each other are described, but the "holding portion" is not limited to this. It may also be a portion that restricts the movement of a part of the terminals in these two directions by abutting or approaching from the two directions where a part of the terminals face each other.

[0293] In addition, the first housing and the second housing may be joined by welding or other means.

[0294] In addition, in the above embodiment, the first housing contacts the second housing, but the first housing and the second housing may also be arranged so as not to contact each other.

[0295] In addition, in the above embodiment, the direction perpendicular to the substrate on which the connector is mounted is the fitting direction with the mating-side connector. It may also be a connector in which the direction along the substrate on which the connector is mounted is set as the fitting direction.

[0296] In addition, in the above embodiment, the convex portion of the displacement restricting mechanism is formed on the first housing, and the concave portion is formed on the second housing, but a concave portion may be formed on the first housing and a convex portion may be formed on the second housing.

[0297] In addition, in the above embodiment, the engaging claw portion of the anti-separation mechanism is formed on the first housing, and the locking portion is formed on the second housing, but a locking portion may be formed on the first housing and an engaging claw portion may be formed on the second housing.

[0298] In addition, in the above-described embodiment, the fitting housing 30 as the first housing or the mounting housing 40 as the second housing is a component entirely formed of resin. However, the "first housing" and "second housing" of the present disclosure are not limited thereto. For example, the first housing or the second housing may also be a component constituted by combining resin and metal. For example, in the above-described embodiment, the protruding claw portion 35 as the "engagement claw portion" is formed of resin, but the engagement claw portion may also be formed of metal.

[0299] In addition, in the above-described embodiment, the power terminal 20 does not have a locking projection (first side press-in portion) for press-fitting the fitting housing 30 as the first housing. The "power terminal" of the present disclosure is not limited to not having the first side press-in portion. For example, the power terminal may also have both the first side press-in portion and the second side press-in portion.

[0300] In addition, in the above-described embodiment, the XY-direction displacement restricting mechanism 34, 47 as the "displacement restricting mechanism" is constituted by a plurality of positioning recesses 47 and a plurality of positioning projections 34. However, the "displacement restricting mechanism" of the present disclosure may also be constituted by one positioning recess and one positioning projection.

[0301] In addition, in the above-described embodiment, the space formed by the positioning recess 47 is substantially rectangular parallelepiped-shaped, and the positioning projection 34 is substantially rectangular parallelepiped-shaped. The "recess" and "projection" of the present disclosure are not limited thereto. For example, the projection may also be other shapes such as cylindrical shape.

[0302] In addition, in the above-described embodiment, the XY-direction displacement restricting mechanism 34, 47 as the displacement restricting mechanism is configured such that the fitting housing 30 can be displaced within a certain range in two directions in the XY direction with respect to the mounting housing 40. The "displacement restricting mechanism" of the present disclosure is not limited thereto. The displacement restricting mechanism of the present disclosure may also be configured such that the projection is press-fitted into the recess.

[0303] In addition, in the above-described embodiment, a method of disposing the fitting housing 30 and the mounting housing 40 inside a frame-shaped jig (not shown) that surrounds the fitting housing 30 and the mounting housing 40 in the XY direction and inserting the terminals 10, 20 in a state where the positions of the fitting housing 30 and the mounting housing 40 in the XY direction are aligned has been described. However, the manufacturing method of the connector of the present disclosure is not limited thereto.

[0304] The frame-shaped jig that surrounds the fitting housing 30 and the mounting housing 40 in the XY direction is formed slightly larger, and the terminals 10 and 20 can be inserted in a state where the fitting housing 30 and the mounting housing 40 are arranged inside the jig. That is, by the displacement restricting mechanism or the jig, the XY direction (the direction in the plane orthogonal to the terminal insertion direction) of the two housings is positioned to a certain extent, or it can be set to a state where it can be slightly displaced within a certain range in both directions of the XY direction. In this state, the terminals are inserted. According to this method, even if there is a misalignment in the position in the XY direction between the terminal holding portions of the two housings due to the manufacturing tolerance of the housings, the two housings can be relatively displaced in such a way that the misalignment is eliminated at the stage of inserting the terminals.

[0305] In addition, in the above-described embodiment, the terminal (signal terminal 10) has a first side press-fitting portion and a second side press-fitting portion, and the separation between the first housing and the second housing is suppressed by the terminal, but the terminal of the present disclosure is not limited to this.

[0306] In addition, the separation between the first housing and the second housing can also be suppressed by a metal component other than the terminal. For example, the connector of the present disclosure is a metal component having a soldering fixing portion soldered to a substrate, and may also include a metal component having a first side press-fitting portion and a second side press-fitting portion. In addition, for example, the connector of the present disclosure is a metal component without a soldering fixing portion, and may also include a metal component having a first side press-fitting portion and a second side press-fitting portion. In addition, these metal components may also be components that function as shielding components for suppressing the propagation of electromagnetic waves.
