Abstract

A connector and a connector assembly are disclosed. The connector includes a plurality of terminals and a housing. The housing has an insertion portion extending in an up-down direction. The insertion portion has a first side portion and a second side portion in a width direction perpendicular to the up-down direction. Each terminal has an insertion end portion and a second extension portion. The second side portion has a permitting portion and a restricting portion. The permitting portion is closer to the insertion end portion than the restricting portion in the up-down direction. The connector has a gap between the permitting portion and the second extension portion in the width direction. The permitting portion allows the second extension portion to partially move into the gap. The restricting portion contacts the second extension portion without a gap in the width direction, thereby restricting movement of the second extension portion in the width direction.

Description

Technical Field

[0001] The present invention relates to a connector that is compatible with a mating connector, and a connector assembly comprising a connector and a mating connector. Background Technology

[0002] For example, this type of connector is disclosed in JP-B 5553502 (Patent Document 1).

[0003] like Figure 40 As shown in Patent Document 1, the second connector 900 or connector 900 is mating with the first connector 950 or mating connector 950 in the Z direction. Connector 900 includes a second housing 910 or housing 910 and a second terminal 920 or terminal 920. The terminal 920 is held by the housing 910. Each terminal 920 has a first contact portion 922 or first contact point 922 and an extension 923. The extension 923 is provided with a contact protrusion 924 or locking portion 924, and a second contact portion 926 or second contact point 926. The mating connector 950 includes a first housing 960 or mating housing 960, and a first terminal 970 or mating terminal 970. The mating terminal 970 is held by the mating housing 960. Each mating terminal 970 has a first contact portion 972 or main contact point 972, and a second contact portion 976 or support contact point 976. When connector 900 and mating connector 950 mate, the first contact point 922 of terminal 920 connects to the main contact point 972 of mating terminal 970, and the second contact point 926 of terminal 920 connects to the support contact point 976 of mating terminal 970. Additionally, when connector 900 and mating connector 950 mate, the locking portion 924 of terminal 920 engages with the support contact point 976 of mating terminal 970. In other words, the support contact point 976 of mating terminal 970 also serves as a mating locking portion, configured to engage with locking portion 924.

[0004] For example, excessive insertion force when a connector mates with a mating connector can damage the connector terminals and / or the connector housing. Therefore, it is necessary to reduce the insertion force when the connector mates with the mating connector.

[0005] On the other hand, from the perspective of electrical reliability, it is desirable for the connector terminals to contact the mating terminals of the mating connector in a mating state where the connector and the mating connector are matched with each other. Summary of the Invention

[0006] The purpose of this invention is to provide a connector and connector assembly that requires reduced insertion force when mated with a mating connector, and that enables the terminals of the connector to make electrical contact with the mating terminals of the mating connector in a mated state.

[0007] To achieve the above object, the present application adopts the following technical solutions:

[0008] The connector according to one aspect (first aspect) of the present application is a connector which is mateable with a mating connector having mating terminals in an up-down direction. The connector includes a plurality of terminals and a housing. The housing holds the terminals. The housing has an interposition portion extending in the up-down direction. The interposition portion has a first side portion and a second side portion in a width direction perpendicular to the up-down direction. Each of the terminals has an insertion end portion, a first extension portion, and a second extension portion. The insertion end portion has a U shape. The first extension portion and the second extension portion extend from the insertion end portion in the up-down direction. The interposition portion is positioned between the first extension portion and the second extension portion in the width direction. The first extension portion is provided with a first contact point. The first contact point contacts the mating terminal when the connector is mated with the mating connector. The second extension portion is provided with a second contact point. The second contact point contacts the mating terminal when the connector is mated with the mating connector. The first side portion contacts the first extension portion. The second side portion has a permitted portion and a restricted portion. The permitted portion is closer to the insertion end portion than the restricted portion in the up-down direction. The connector has a gap between the permitted portion and the second extension portion in the width direction. The permitted portion allows the second extension portion to partially move into the gap. The restricted portion contacts the second extension portion without a gap in the width direction, thereby restricting movement of the second extension portion in the width direction.

[0009] The connector assembly according to another aspect (second aspect) of the present application includes the connector according to the first aspect and a mating connector which is mateable with the connector in the up-down direction. The mating connector includes a plurality of mating terminals and a mating housing. The mating housing holds the mating terminals. Each of the mating terminals has a mating-restricted portion, a coupling portion, a support contact point, a support portion, and a main contact point. Movement of the mating-restricted portion in the width direction is restricted by the mating housing. The coupling portion extends from the mating-restricted portion. The support contact point is supported by the coupling portion. The support portion extends from the support contact point and is at least partially elastically deformable. The main contact point is supported by the support portion. The first contact point contacts the main contact point when the connector is mated with the mating connector. The second contact point contacts the support contact point when the connector is mated with the mating connector.

[0010] The present application has the following advantages:

[0011] The connector according to the present application is configured as follows: the connector has a gap between the permitted portion and the second extension portion in the width direction; and the permitted portion allows the second extension portion to partially move into the gap. Therefore, the connector according to the present application requires a reduced insertion force when the connector is mated with the mating connector.

[0012] Further, in the connector of the present application, the restriction portion contacts the second extension portion without a gap in the width direction, thereby restricting movement of the second extension portion in the width direction. Therefore, in the connector of the present application, the second contact point of the terminal of the connector can be positioned with high accuracy with respect to the mating terminal of the mating connector. Therefore, the connector of the present application is configured so that a set contact force between the mating terminal and the second contact point is obtained in a mating state in which the connector and the mating connector are mated.

[0013] That is, the connector of the present application requires reduced insertion force when the connector and the mating connector are mated, and the connector of the present application enables the terminal of the connector to electrically contact the mating terminal of the mating connector as designed in a mating state in which the connector and the mating connector are mated.

[0054] In the mating connector 950 of Patent Document 1, the main contact point 972 is supported by a spring softer than another spring supporting the support contact point 976. Therefore, the force with which the support contact point 976 pushes the terminal 920 is greater than the force with which the main contact point 972 pushes the terminal 920. In particular, the mating connector 950 of Patent Document 1 is configured so that the support contact point 976 also functions as a mating lock portion. Therefore, when the contact protrusion 924 crosses the support contact point 976, the contact protrusion 924 of the terminal 920 is subjected to a large reaction force, and thus the connector 900 has a disadvantage that the insertion force needs to be increased when the connector 900 is mated with the mating connector 950.

[0055] To solve this disadvantage, the terminal 920 should be configured to be elastically deformable so that the difference between the force applied to the terminal 920 from the support contact point 976 and the force applied to the terminal 920 from the main contact point 972 is reduced when the connector 900 is inserted into the mating connector 950. Specifically, this disadvantage can be solved by providing a gap between the extension 923 provided with the second contact point 926 and the housing 910 so that the extension 923 is elastically deformable.

[0056] On the other hand, elastically deforming the extension 923 of the terminal 920 causes a new problem that the position of the second contact point 926 in the X direction can be unstable. To solve this new problem, the present application conceives that a portion of the extension 923 on the positive Z side is intentionally brought into contact with the housing 910 so that the second contact point 926 is positioned with high accuracy in the X direction. The present application is derived from the above-described concept.

[0057] As Figure 1 shown, the connector assembly 10 of the embodiment of the present application includes a connector 100 and a mating connector 800.

[0058] With reference to Figure 27 , the mating connector 800 of the embodiment is configured to be mounted on a circuit board 880 having pads (not shown) on its surface. As Figure 1 , Figure 7 and Figure 27As shown, in this embodiment, the mating connector 800 is mated with the connector 100 in the vertical direction. In this embodiment, the vertical direction is the Z direction. Specifically, it is assumed that upward is the positive Z direction and downward is the negative Z direction.

[0059] like Figure 28 As shown, the mating connector 800 in this embodiment includes a plurality of mating terminals 820, 850 and a mating housing 810.

[0060] Reference Figure 28 In this embodiment, the mating housing 810 is made of an insulator. The mating housing 810 holds the mating terminals 820 and 850. Figure 28 and Figure 30 As shown, the matching housing 810 has a surrounding portion 811, a matching surrounding portion receiving portion 812, an island-shaped portion 814, and an adjustment portion 816.

[0061] from Figure 28 and Figure 29 To understand this, the surrounding portion 811 in this embodiment has a generally rectangular tube shape extending in the vertical direction. The surrounding portion 811 defines the outer end of the mating housing 810 in the width direction perpendicular to the vertical direction. In this embodiment, the width direction is the X direction. The width direction is also called the front-to-back direction. Specifically, it is assumed that the front is the positive X direction and the rear is the negative X direction. The surrounding portion 811 defines the outer end of the mating housing 810 in the spacing direction perpendicular to both the vertical and width directions. In this embodiment, the spacing direction is the Y direction.

[0062] like Figure 27 and Figure 28 As shown, in this embodiment, the matching surrounding portion receiving portion 812 is surrounded by the surrounding portion 811 in a plane perpendicular to the vertical direction. The matching surrounding portion receiving portion 812 is a recess that is recessed downward in the vertical direction. Specifically, the matching surrounding portion receiving portion 812 has a lower surface 8122. The lower surface 8122 defines the lower end of the matching surrounding portion receiving portion 812.

[0063] like Figure 27 and Figure 28 As shown, in this embodiment, the island-shaped portion 814 extends upward from the lower surface 8122 in the vertical direction. The island-shaped portion 814 is surrounded by the matching surrounding portion receiving portion 812 in a plane perpendicular to the vertical direction.

[0064] like Figure 30 and Figure 31 As shown, each adjustment part 816 in this embodiment is positioned at the outer end of the matching housing 810 along the width direction.

[0065] Reference Figure 32 In this embodiment, each mating terminal 820, 850 is made of metal. For example... Figure 28As shown, terminals 820 and 850 are arranged in two rows along the width direction, namely the front row and the back row. The mating terminals 820 and 850 in each row are arranged along the spacing direction. The mating terminals 820 and 850 include a first mating terminal 820 and a second mating terminal 850.

[0066] like Figure 36 As shown, each mating first terminal 820 in this embodiment has a mating limiting portion 822, a connecting portion 823, a supporting contact point 824, a mating locking portion 827, a supporting portion 826, and a main contact point 828. The mating limiting portion 822 is also referred to as the mating first limiting portion 822. The connecting portion 823 is also referred to as the first connecting portion 823. The supporting contact point 824 is also referred to as the first supporting contact point 824. The mating locking portion 827 is also referred to as the mating first locking portion 827. The supporting portion 826 is also referred to as the first supporting portion 826. The main contact point 828 is also referred to as the first main contact point 828.

[0067] like Figure 36 As shown, in this embodiment, the matching limiting part 822 extends in the vertical direction. For example... Figure 30 As shown, the movement of the matching and limiting part 822 in the width direction is limited by the matching housing 810. Specifically, the matching and limiting part 822 is press-fitted into the matching housing 810.

[0068] like Figure 36 As shown, in this embodiment, the connecting portion 823 extends from the mating and restricting portion 822. More specifically, the connecting portion 823 extends inward from the mating and restricting portion 822 in the width direction and is bent so that it extends downward in the vertical direction.

[0069] like Figure 36 As shown, in this embodiment, the support contact point 824 faces inward along the width direction. The support contact point 824 is supported by the connecting portion 823.

[0070] See Figure 36 In this embodiment, the support portion 826 extends from the support contact point 824 and is at least partially elastically deformable. The support portion 826 extends downward in the vertical direction and outward in the width direction from the support contact point 824, and is bent to extend inward in the width direction, and is further bent to extend upward in the vertical direction and outward in the width direction.

[0071] like Figure 36 As shown, in this embodiment, the main contact point 828 faces outward along the width direction. The main contact point 828 is supported by the support portion 826.

[0072] like Figure 36 As shown, each mating first terminal 820 has a mating mounting portion 825. The mating mounting portion 825 is also referred to as the mating first mounting portion 825.

[0073] As shown in Figure 36 the matching mounting portion 825 of the present embodiment extends outward in the width direction from the matching restricted portion 822. The matching mounting portion 825 defines the outer end of the matching first terminal 820 in the width direction. The matching mounting portion 825 defines the lower end of the matching first terminal 820 in the up-down direction. When the mating connector 800 is mounted on the circuit board 880 as shown in Figure 27 the matching mounting portion 825 is soldered to the solder pad.

[0074] As shown in Figure 39 the matching second terminal 850 of the present embodiment has a matching restricted portion 852, a coupling portion 853, a support contact point 854, a matching locking portion 857, a support portion 856, a main contact point 858, and an adjusted portion 859. However, the present application is not limited thereto, and the matching second terminal 850 can also not have the adjusted portion 859. The matching restricted portion 852 is also referred to as a matching second restricted portion 852. The coupling portion 853 is also referred to as a second coupling portion 853. The support contact point 854 is also referred to as a second support contact point 854. The matching locking portion 857 is also referred to as a matching second locking portion 857. The support portion 856 is also referred to as a second support portion 856. The main contact point 858 is also referred to as a second main contact point 858.

[0075] As shown in Figure 39 the matching restricted portion 852 of the present embodiment extends in the up-down direction. As shown in Figure 31 the movement of the matching restricted portion 852 in the width direction is restricted by the matching housing 810. Specifically, the matching restricted portion 852 is press-fitted into the matching housing 810.

[0076] As shown in Figure 39 the coupling portion 853 of the present embodiment extends from the matching restricted portion 852. More specifically, the coupling portion 853 extends inward in the width direction from the matching restricted portion 852 and is bent so as to extend downward in the up-down direction.

[0077] As shown in Figure 39 the support contact point 854 of the present embodiment faces outward in the width direction. The support contact point 854 is supported by the coupling portion 853.

[0078] Referring to Figure 39 the support portion 856 of the present embodiment extends from the support contact point 854 and is at least partially elastically deformable. The support portion 856 extends downward in the up-down direction and inward in the width direction from the support contact point 854 and is bent so as to extend outward in the width direction, and is further bent so as to extend upward in the up-down direction and inward in the width direction.

[0079] As shown in Figure 39As shown, in this embodiment, the main contact point 858 faces inward along the width direction. The main contact point 858 is supported by the support portion 856.

[0080] like Figure 39 As shown, in this embodiment, the adjustable portion 859 is connected to the support portion 856 along the width direction. The adjustable portion 859 defines the outer end of the mating second terminal 850 in the width direction. Figure 31 As shown, the adjustable part 859 is located below the adjusting part 816 in the vertical direction. The upward movement of the adjustable part 859 in the vertical direction is adjusted by the adjusting part 816.

[0081] like Figure 39 As shown, each mating second terminal 850 has a mating mounting portion 855. The mating mounting portion 855 is also referred to as the mating second mounting portion 855.

[0082] like Figure 39 As shown, in this embodiment, the mating mounting portion 855 extends inward from the mating restricted portion 852 along the width direction. The mating mounting portion 855 defines the inner end of the mating second terminal 850 in the width direction. The mating mounting portion 855 defines the lower end of the mating second terminal 850 in the vertical direction. When the mating connector 800 is mounted... Figure 27 When the circuit board 880 shown is used, the mating mounting part 855 is soldered to the pad.

[0083] Reference Figure 8 In this embodiment, the connector 100 is configured to be mounted on a circuit board 750, the circuit board 750 having pads (not shown) on its surface. Figure 1 , Figure 7 and Figure 27 As shown, in this embodiment, the connector 100 can be matched with the mating connector 800 having mating terminals 820 and 850 in the vertical direction.

[0084] like Figure 8 As shown, connector 100 includes multiple terminals 400, 500 and housing 200.

[0085] Reference Figure 15 In this embodiment, the housing 200 is made of an insulator. For example... Figure 11 As shown, the housing 200 holds terminals 400 and 500. The housing 200 has two long wall portions 220, two short wall portions 230, and an island-shaped receiving portion 250. However, the invention is not limited thereto, and the number of long wall portions 220 may also be one.

[0086] Reference Figure 11 In this embodiment, each elongated wall portion 220 defines the outer end of the housing 200 in the width direction. (Refer to...) Figure 17Each long wall portion 220 has a height in the up-down direction and extends in a pitch direction perpendicular to the up-down direction and the width direction. As shown in FIG. 2, Figure 11 Each long wall portion 220 couples two short wall portions 230 to each other in the pitch direction. Referring to Figure 16 and Figure 17 Each long wall portion 220 has a first wall surface 222 and a second wall surface 224.

[0087] As shown in FIG. 2, Figure 17 Each long wall portion 220 is formed with a plurality of interposed portions 300. Specifically, the housing 200 has the interposed portions 300, each of which extends in the up-down direction.

[0088] As shown in FIG. 2, Figure 16 and Figure 17 Each interposed portion 300 of the present embodiment has a first side portion 310 and a second side portion 320 in the width direction perpendicular to the up-down direction.

[0089] As shown in FIG. 2, Figure 13 and Figure 14 The first side portion 310 of the present embodiment intersects the width direction. More specifically, the first side portion 310 is perpendicular to the width direction. The first side portion 310 extends in the up-down direction.

[0090] As shown in FIG. 2, Figure 13 and Figure 14 The second side portion 320 of the present embodiment intersects the width direction. The second side portion 320 extends in the up-down direction.

[0091] As shown in FIG. 2, Figure 13 and Figure 14 In each interposed portion 300, the orientation of the width direction toward which the second side portion 320 faces is opposite to the orientation of the width direction toward which the first side portion 310 faces. In two interposed portions 300 adjacent in the pitch direction, the orientation of the width direction toward which the first side portion 310 of one of the two interposed portions 300 faces is opposite to the orientation of the width direction toward which the first side portion 310 of the other of the two interposed portions 300 faces. In the two interposed portions 300 adjacent in the pitch direction, the orientation of the width direction toward which the second side portion 320 of one of the two interposed portions 300 faces is opposite to the orientation of the width direction toward which the second side portion 320 of the other of the two interposed portions 300 faces.

[0092] As shown in FIG. 2, Figure 17 The second side portion 320 has a permission portion 322 and a restriction portion 324.

[0093] As shown in FIG. 2, Figure 13 and Figure 14As shown, in this embodiment, the allowable portion 322 intersects the vertical direction. The allowable portion 322 also intersects the width direction. More specifically, the allowable portion 322 is inclined to both the vertical and width directions. The allowable portion 322 is positioned below the restricting portion 324 along the vertical direction. The allowable portion 322 defines the lower end of the insertion portion 300 in the vertical direction.

[0094] like Figure 13 and Figure 14 As shown, in this embodiment, the limiting portion 324 intersects the width direction. More specifically, the limiting portion 324 is perpendicular to the width direction. The limiting portion 324 is positioned above the allowing portion 322 in the vertical direction.

[0095] like Figure 17 As shown, the first side portion 310 and the second side portion 320 are alternately arranged along the spacing direction on the first wall surface 222. Figure 16 As shown, the first side portion 310 and the second side portion 320 are alternately arranged along the spacing direction on the second wall surface 224.

[0096] like Figure 11 As shown, in this embodiment, each short wall portion 230 defines the outer end of the housing 200 in the spacing direction. For example... Figure 8 and Figure 11 As shown, each short wall portion 230 has height in the vertical direction and extends in the width direction. Each short wall portion 230 connects two long wall portions 220 to each other in the width direction.

[0097] like Figure 8 As shown, the island-shaped portion receiving portion 250 in this embodiment is a recess that is recessed upward in the vertical direction. Specifically, the island-shaped portion receiving portion 250 has an upper surface 252. The upper surface 252 defines the upper end of the island-shaped portion receiving portion 250.

[0098] like Figure 15 As shown, the housing 200 has a plurality of holes 240, each hole 240 penetrating the housing 200 in the vertical direction.

[0099] like Figure 13 As shown, in this embodiment, each hole 240 is disposed in the island-shaped receiving portion 250. (As indicated...) Figure 15 As shown, each hole 240 penetrates the upper surface 252 of the island-shaped receiving portion 250 in the vertical direction.

[0100] like Figure 15 As shown, the housing 200 has a plurality of elongated holes 280.

[0101] like Figure 15 As shown, in this embodiment, each elongated hole 280 penetrates the upper surface 252 of the island-shaped receiving portion 250 in the vertical direction. Figure 11As shown, each elongated hole 280 is provided in the island-shaped receiving portion 250. (As indicated...) Figure 15 As shown, each elongated hole 280 has a closed periphery in a plane perpendicular to the vertical direction. Each elongated hole 280 has a second retaining portion 282.

[0102] like Figure 15 As shown, in this embodiment, the second retaining portion 282 is located at the outer end of the elongated hole 280 in the width direction. The second retaining portion 282 is composed of two grooves facing each other in the spacing direction. As described above, the elongated hole 280, on which the second retaining portion 282 is provided, has a closed periphery in a plane perpendicular to the vertical direction. Therefore, the inner ends of the two grooves forming the second retaining portion 282 in the width direction are connected to each other through the closed periphery of the elongated hole 280.

[0103] like Figure 11 As shown, in this embodiment, terminals 400 and 500 are arranged along the spacing direction. More specifically, terminals 400 and 500 are arranged in two rows along the width direction, namely a front row and a rear row, and the terminals 400 and 500 in each row are arranged along the spacing direction. The two rows of terminals 400 and 500 correspond to the two elongated wall portions 220 respectively. From Figure 21 and Figure 25 To understand this, terminals 400 and 500 include a first terminal 400 and a second terminal 500, and the first terminal 400 and the second terminal 500 have different shapes from each other.

[0104] like Figure 18 As shown, in each row, the first terminal 400 and the second terminal 500 are arranged alternately in the spacing direction. In other words, the first terminal 400 and the second terminal 500 are adjacent to each other in the spacing direction.

[0105] like Figure 11 As shown, in the two rows of terminals 400 and 500, the first terminals 400 in this embodiment are arranged in an alternating configuration. Each first terminal 400 is attached to the housing 200. Each first terminal 400 is attached to the elongated wall portion 220.

[0106] like Figure 21 As shown, each first terminal 400 has an insertion end 410, a first extension 420, and a second extension 440. Specifically, the first extension 420 and the second extension 440 extend from the insertion end 410 in a vertical direction.

[0107] like Figure 21 As shown, the insertion end 410 of this embodiment has a U-shaped shape. Specifically, when the first terminal 400 is viewed along the spacing direction, the insertion end 410 has a U-shaped shape. The insertion end 410 defines the lower end of the first terminal 400 in the vertical direction. Figure 13As shown, the allowable portion 322 is closer to the insertion end 410 in the vertical direction than the restrictive portion 324. The lower end of the insertion portion 300 does not contact the insertion end 410. Specifically, the lower end of the allowable portion 322 does not contact the insertion end 410.

[0108] like Figure 21 As shown, in this embodiment, the first extension 420 extends from the insertion end 410 in a vertical direction. Specifically, the first extension 420 extends upward from the insertion end 410 in a vertical direction. Figure 13 As shown, the first side portion 310 faces the first extension portion 420 in the width direction. The first side portion 310 contacts the first extension portion 420. Specifically, the first side portion 310 contacts the first extension portion 420 in the width direction.

[0109] like Figure 21 As shown, the first extension 420 is provided with a first contact point 422. Note that the first extension 420 is not provided with a locking part.

[0110] like Figure 13 and Figure 14 As shown, in this embodiment, the first contact point 422 faces inward in the width direction. Figure 5 and Figure 6 As shown, when connector 100 mates with mating connector 800, the first contact point 422 contacts mating terminal 820. Specifically, when connector 100 mates with mating connector 800, the first contact point 422 contacts main contact point 828.

[0111] like Figure 21 As shown, in this embodiment, the second extension 440 extends vertically from the insertion end 410. Specifically, the second extension 440 extends upwardly from the insertion end 410 in the vertical direction. The first extension 420 is located inside the second extension 440 in the width direction. Figure 13 As shown, the second side portion 320 faces the second extension portion 440 in the width direction. A portion of the second side portion 320 contacts a portion of the second extension portion 440 in the width direction.

[0112] like Figure 13 As shown, the insertion portion 300 is located between the first extension portion 420 and the second extension portion 440 in the width direction.

[0113] like Figure 13 As shown, connector 100 has gaps 700, each gap 700 positioned in the width direction between allowance 322 and second extension 440. In other words, allowance 322 is separated from second extension 440 in the width direction. Allowance 322 allows second extension 440 to partially move into gap 700. See also Figure 5 and Figure 13This provides the following advantages: at the start of mating of the connector 100 with the mating connector 800, the second extension portion 440 is partially elastically deformed toward the allowance portion 322, and the insertion end portion 410 moves toward the first extension portion 420, whereby the insertion end portion 410 can easily cross over the support contact point 824. Thus, the connector 100 requires a reduced insertion force when the connector 100 is mated with the mating connector 800.

[0114] In the connector 900 of Patent Document 1, the extension portion 923 is slightly separated from the housing 910, and the distance between the extension portion 923 and the housing 910 can vary in manufacture. Thus, the connector 900 of Patent Document 1 has the following disadvantage: in a mating state in which the connector 900 and the mating connector 950 are mated with each other, the second contact point 926 is difficult to electrically contact the mating terminal 970 as designed.

[0115] In contrast, as shown in Figure 13 , the connector 100 of the present embodiment is configured such that the restriction portion 324 contacts the second extension portion 440 without a gap in the width direction, thus restricting movement of the second extension portion 440 in the width direction. Referring to Figure 5 and Figure 13 , this makes it possible for the second contact point 442 to be positioned with high accuracy with respect to the mating terminal 820 in a mating state in which the connector 100 and the mating connector 800 are mated with each other. Thus, unlike the connector 900 of Patent Document 1, the connector 100 of the present embodiment makes it possible for the second contact point 442 to electrically contact the mating terminal 820 as designed in a mating state in which the connector 100 and the mating connector 800 are mated.

[0116] As shown in Figure 21 , the second extension portion 440 is provided with the second contact point 442.

[0117] As shown in Figure 19 , the second contact point 442 of the present embodiment faces outward in the width direction. As shown in Figure 5 , the second contact point 442 contacts the mating terminal 820 when the connector 100 and the mating connector 800 are mated. Specifically, the second contact point 442 contacts the support contact point 824 when the connector 100 and the mating connector 800 are mated. As shown in Figure 13 , the position of the second contact point 442 does not overlap the restriction portion 324 in the up-down direction.

[0118] Referring to Figure 13 and Figure 30 , the terminal 400 has a portion corresponding to the restriction portion 324, and the distance Dl from this portion to the second contact point 442 on the terminal 400 is shorter than the distance D2 from the mating restriction portion 822 to the support contact point 824 on the mating terminal 820. Thus, referring toFigure 5 Based on the completion of the mating of the connector 100 and the mating connector 800, the movement of the second contact point 442 is more difficult than the movement of the support contact point 824, so that the second contact point 442 of the first terminal 400 of the connector 100 can be positioned with higher accuracy with respect to the mating first terminal 820 of the mating connector 800. Thus, the connector 100 of the present embodiment enables the second contact point 442 to further make electrical contact with the mating terminal 820 as designed in the mating state in which the connector 100 and the mating connector 800 are mated.

[0119] As shown in Figure 19 , the second extension 440 is provided with a locking portion 444.

[0120] As described above, the second extension 440 is provided with the locking portion 444, while the first extension 420 is not provided with the locking portion. However, the present application is not limited to this. Specifically, the first terminal 400 can be modified so that the first extension 420 has the locking portion and the second extension 440 does not have the locking portion. Alternatively, the first terminal 400 can be modified so that the first extension 420 is provided with the locking portion and the second extension 440 is provided with the locking portion 444.

[0121] Referring to Figure 5 , the locking portion 444 of the present embodiment locks the mating of the connector 100 and the mating connector 800 when the connector 100 and the mating connector 800 are mated. More specifically, referring to Figure 5 and Figure 30 , the locking portion 444 and the mating locking portion 827 lock the mating of the connector 100 and the mating connector 800 when the connector 100 and the mating connector 800 are mated to each other.

[0122] As shown in Figure 19 , the second extension 440 has a pressing portion 446.

[0123] As shown in Figure 19 , the pressing portion 446 of the present embodiment is located at the upper end of the second extension 440. The pressing portion 446 is positioned around the upper end of the first terminal 400. As shown in Figure 13 , the pressing portion 446 is located at the same position as that of the limiting portion 324 in the up-down direction. The pressing portion 446 is in contact with the limiting portion 324 in the width direction. The pressing portion 446 is positioned above the allowance portion 322 in the up-down direction.

[0124] As shown in Figure 21 , each of the first terminals 400 of the present embodiment has a first press-fit portion 460.

[0125] As shown in Figure 21As shown, in this embodiment, the first press-fit portion 460 is disposed at the end of the first extension 420. More specifically, the first press-fit portion 460 is located at the upper end of the first extension 420 in the vertical direction. A portion of the pressing portion 446 is located below the first press-fit portion 460 in the vertical direction. Figure 13 As shown, a portion of the limiting portion 324 is located below the first press-fit portion 460 in the vertical direction. Each first press-fit portion 460 of each first terminal 400 is press-fitted into each hole 240. Specifically, the first press-fit portions 460 of each row of first terminals 400 are press-fitted into holes 240, which are provided inside corresponding elongated wall portions 220 in the width direction.

[0126] like Figure 21 As shown, each first terminal 400 has a first mounting portion 470.

[0127] like Figure 21 As shown, in this embodiment, the first mounting portion 470 extends from the second extension portion 440. Specifically, the first mounting portion 470 extends outward from the second extension portion 440 in the width direction. The first mounting portion 470 defines the outer end of the first terminal 400 in the width direction. The first mounting portion 470 defines the upper end of the first terminal 400 in the vertical direction. (Refer to...) Figure 8 When the connector 100 is mounted on the circuit board 750, the first mounting part 470 is soldered to the pads of the circuit board 750.

[0128] like Figure 21 As shown, each first terminal 400 has an insertion receiving portion 480.

[0129] like Figure 21 As shown, in this embodiment, the insertion receiving portion 480 is located between the first extension 420 and the second extension 440 along the width direction. The insertion receiving portion 480 is located above the insertion end 410 along the vertical direction. Figure 13 and Figure 21 As shown, with the first terminal 400 attached to the housing 200, the insertion part 300 is accommodated in the insertion part accommodating part 480.

[0130] Reference Figure 13 and Figure 22 Before the first terminal 400 is attached to the housing 200, the distance D3 in the width direction between the first press-fit portion 460 and the pressing portion 446 is less than the dimension S in the width direction of the insertion portion 300. Therefore, referring to... Figure 13 , Figure 21 and Figure 22, based on the first terminal 400 being attached to the case 200, the insertion portion 300 is accommodated in the insertion portion accommodation portion 480 of the first terminal 400 while the distance D3 in the width direction between the first press-fitting portion 460 and the press portion 446 increases. Also, referring to Figure 13 、 Figure 21 and Figure 22 , in a state in which the first terminal 400 is attached to the case 200, the press portion 446 is in pressure contact with the restriction portion 324.

[0131] As shown in Figure 11 , in the two rows of terminals 400, 500, the second terminal 500 of the present embodiment is arranged in a staggered configuration. Each second terminal 500 is attached to the case 200. Each second terminal 500 is attached to the long wall portion 220.

[0132] As shown in Figure 25 , each second terminal 500 has an insertion end portion 510, a first extension portion 520, and a second extension portion 540. Specifically, the first extension portion 520 and the second extension portion 540 extend in the up-down direction from the insertion end portion 510.

[0133] As shown in Figure 25 , the insertion end portion 410 of the present embodiment has a U-shaped shape. Specifically, when the second terminal 500 is viewed in the pitch direction, the insertion end portion 510 has a U-shaped shape. The insertion end portion 510 defines a lower end of the second terminal 500 in the up-down direction. As shown in Figure 14 , the allowance portion 322 is closer to the insertion end portion 510 in the up-down direction than the restriction portion 324. The lower end of the insertion portion 300 does not contact the insertion end portion 510. Specifically, the lower end of the allowance portion 322 does not contact the insertion end portion 510.

[0134] As shown in Figure 25 , the first extension portion 520 of the present embodiment extends in the up-down direction from the insertion end portion 510. Specifically, the first extension portion 520 extends upward in the up-down direction from the insertion end portion 510. As shown in Figure 14 , the first side portion 310 faces the first extension portion 520 in the width direction. The first side portion 310 is in contact with the first extension portion 520. Specifically, the first side portion 310 is in contact with the first extension portion 520 in the width direction.

[0135] As shown in Figure 12 , the first extension portion 520 and the second extension portion 440 are alternately arranged in the pitch direction on the first wall surface 222.

[0136] As shown in Figure 13 , the first extension portion 520 is provided with a first contact point 522. Note that the first extension portion 520 is not provided with a locking portion.

[0137] AsFigure 14 and Figure 5 As shown, in this embodiment, the first contact point 522 faces outwards in the width direction. Figure 6 and Figure 25 As shown, when connector 100 mates with mating connector 800, the first contact point 522 contacts mating terminal 850. Specifically, when connector 100 mates with mating connector 800, the first contact point 522 contacts main contact point 858.

[0138] like Figure 14 As shown, in this embodiment, the second extension 540 extends vertically from the insertion end 510. Specifically, the second extension 540 extends upwardly from the insertion end 510 in the vertical direction. The second extension 540 is located inside the first extension 520 in the width direction. Figure 14 As shown, the second side portion 320 faces the second extension portion 540 in the width direction. A portion of the second side portion 320 contacts a portion of the second extension portion 540 in the width direction.

[0139] like Figure 14 As shown, the insertion portion 300 is located between the first extension portion 520 and the second extension portion 540 in the width direction.

[0140] like Figure 6 As shown, connector 100 has gaps 700, each gap 700 positioned in the width direction between allowance 322 and second extension 540. In other words, allowance 322 is separated from second extension 540 in the width direction. Allowance 322 allows second extension 540 to partially move into gap 700. See also Figure 14 and Figure 14 This provides the following advantages: at the beginning of mating of connector 100 with mating connector 800, the second extension 540 partially elastically deforms toward the allowable portion 322, and the insertion end 510 moves toward the first extension 520, thereby allowing the insertion end 510 to easily cross the support contact point 854. Therefore, connector 100 requires a reduced insertion force when mating with mating connector 800.

[0141] like Figure 6 As shown, in this embodiment, the connector 100 is configured such that the limiting portion 324 contacts the second extension portion 540 in the width direction without any gap, thereby limiting the movement of the second extension portion 540 in the width direction. (Refer to...) Figure 14 and Figure 10This makes it possible for the second contact point 542 to be positioned with high accuracy with respect to the mating terminal 850 in a mating state in which the connector 100 and the mating connector 800 are mated to each other. Thus, unlike the connector 900 of Patent Document 1, the connector 100 of the present embodiment makes it possible for the second contact point 542 to electrically contact the mating terminal 850 as designed in a mating state in which the connector 100 and the mating connector 800 are mated.

[0142] As shown in Figure 25 , the first extension 420 and the second extension 540 are alternately arranged in the pitch direction on the second wall surface 224.

[0143] As shown in Figure 14 , the second extension 540 is provided with the second contact point 542.

[0144] As shown in Figure 6 , the second contact point 542 of the present embodiment faces inward in the width direction. As shown in Figure 14 , the second contact point 542 contacts the mating terminal 850 when the connector 100 and the mating connector 800 are mated. Specifically, the second contact point 542 contacts the support contact point 854 when the connector 100 and the mating connector 800 are mated. As shown in Figure 14 , the position of the second contact point 542 does not overlap with the restriction 324 in the up-down direction.

[0145] As shown in Figure 31 and Figure 6 , the terminal 500 has a portion corresponding to the restriction 324, and the distance Dl from this portion to the second contact point 542 on the terminal 500 is shorter than the distance D2 from the mating restriction 852 to the support contact point 854 on the mating terminal 850. Thus, as shown in Figure 25 , based on the completion of the mating of the connector 100 and the mating connector 800, the movement of the second contact point 542 is more difficult than the movement of the support contact point 854, and thus the second contact point 542 of the second terminal 500 of the connector 100 can be positioned with higher accuracy with respect to the mating second terminal 850 of the mating connector 800. Thus, the connector 100 of the present embodiment makes it possible for the second contact point 542 to further electrically contact the mating terminal 850 as designed in a mating state in which the connector 100 and the mating connector 800 are mated.

[0146] As shown in Figure 6 , the second extension 540 is provided with the locking portion 544.

[0147] As described above, the second extension 540 is provided with the locking portion 544, while the first extension 520 is not provided with the locking portion. However, the present application is not limited to this. Specifically, the second terminal 500 can be improved so that the first extension 520 has the locking portion while the second extension 540 does not have the locking portion. Alternatively, the second terminal 500 can be improved so that the first extension 520 is provided with the locking portion while the second extension 540 is provided with the locking portion 544.

[0148] Referring to Figure 6 When the connector 100 is mated with the mating connector 800, the locking portion 544 of the present embodiment locks the mating of the connector 100 and the mating connector 800. More specifically, referring to Figure 31 and Figure 25 When the connector 100 and the mating connector 800 are mated with each other, the locking portion 544 and the mating locking portion 857 lock this mating.

[0149] As shown in Figure 25 , the first extension 520 has a pressing portion 526.

[0150] As shown in Figure 14 , the pressing portion 526 of the present embodiment is located at the upper end of the first extension 520. The pressing portion 526 is positioned around the upper end of the second terminal 500. As shown in Figure 25 , the pressing portion 526 is located at the same position as that of the restricting portion 324 in the up-down direction. The pressing portion 526 is positioned above the permitting portion 322 in the up-down direction. The pressing portion 526 is in contact with the first side portion 310 in the width direction.

[0151] As shown in Figure 25 , each second terminal 500 of the present embodiment has a second press-fit portion 560.

[0152] As shown in Figure 14 , the second press-fit portion 560 of the present embodiment is provided on the second extension 540. More specifically, the second press-fit portion 560 is located at the upper end of the second extension 540 in the up-down direction. A part of the pressing portion 526 is located below the second press-fit portion 560 in the up-down direction. As shown in Figure 14 , a part of the restricting portion 324 is located below the second press-fit portion 560 in the up-down direction.

[0153] Referring to Figure 15 and Figure 25 , the second press-fit portion 560 is press-fitted into the second holding portion 282. Specifically, the second press-fit portion 560 of each row of the second terminal 500 is press-fitted into the second holding portion 282, which is provided on the inner side of the corresponding long wall portion 220 in the width direction.

[0154] As described above, the inner ends in the width direction of the two grooves forming the second holding portion 282 are coupled to each other by the closed periphery of the elongated hole 280. When the second press-fit portion 560 is press-fitted into the second holding portion 282, this prevents the distance between the inner ends in the width direction of the two grooves of the second holding portion 282 in the pitch direction from increasing. Thus, the second holding portion 282 maintains the holding of the second press-fit portion 560.

[0155] As described above, the first terminal 400 of the present embodiment is configured so that the first press-fit portion 460 is provided at the first extension portion 420 inside the second extension portion 440 in the width direction, and the second terminal 500 of the present embodiment is configured so that the second press-fit portion 560 is provided at the second extension portion 540 inside the first extension portion 520 in the width direction. For the manufacture of the connector 100 of the present embodiment, this can simplify the attachment process of the terminals 400, 500 to the housing 200 as follows: the manufacturer forms a blank configured so that the first terminals 400 and the second terminals 500 are connected to the carrier via the connection portions at the outer ends in the width direction of the first terminals 400 and the second terminals 500 in a state where the first terminals 400 and the second terminals 500 are arranged alternately in the pitch direction; the first terminals 400 and the second terminals 500 coupled to each other by the carrier are simultaneously attached to the housing 200; and the first terminals 400 and the second terminals 500 are separated into two parts from the carrier by splitting the connection portions connecting the terminals 400, 500 to the carrier.

[0156] As Figure 25 indicated, each second terminal 500 has a second mounting portion 570.

[0157] As Figure 8 indicated, the second mounting portion 570 of the present embodiment extends from the second extension portion 540. Specifically, the second mounting portion 570 extends inward in the width direction from the second extension portion 540. The second mounting portion 570 defines the inner end of the second terminal 500 in the width direction. The second mounting portion 570 defines the upper end of the second terminal 500 in the up-down direction. Refer to Figure 14 and Figure 25 When the connector 100 is mounted on the circuit board 750, the second mounting portion 570 is soldered to the pad of the circuit board 750.

[0158] As Figure 25 indicated, each second terminal 500 has an interposition portion receiving portion 580.

[0159] As Figure 14 indicated, the interposition portion receiving portion 580 of the present embodiment is located between the first extension portion 520 and the second extension portion 540 in the width direction. The interposition portion receiving portion 580 is located above the insertion end portion 510 in the up-down direction. As Figure 25 and Figure 14As shown, with the second terminal 500 connected to the housing 200, the insertion part 300 is accommodated in the insertion part accommodating part 580.

[0160] Reference Figure 26 and Figure 14 Before the second terminal 500 is connected to the housing 200, the distance D4 in the width direction between the second press-fit portion 560 and the pressing portion 526 is less than the dimension S in the width direction of the insertion portion 300. Therefore, referring to... Figure 25 , Figure 26 and Figure 14 Based on the second terminal 500 being attached to the housing 200, the insertion portion 300 is accommodated in the insertion portion accommodating portion 580 of the second terminal 500, and at the same time, the distance D4 in the width direction between the second press-fit portion 560 and the pressing portion 526 increases. Additionally, referring to... Figure 25 , Figure 26 and Figure 13 With the second terminal 500 attached to the housing 200, the pressing part 526 is in pressure contact with the first side part 310.

[0161] Reference Figure 14 and ​ The first press-fit portion 460 and the second press-fit portion 560 are positioned such that they correspond to each other in the width direction, and the first press-fit portion 460 and the second press-fit portion 560 are alternately arranged in the spacing direction.

[0162] Although the present invention has been described in detail above through embodiments, the present invention is not limited thereto and various changes and substitutions can be made.

[0163] Although the connector 100 in the above embodiment is configured such that the first press-fit portion 460 is disposed at the end of the first extension portion 420, and the first press-fit portion 460 of each row of first terminals 400 is press-fitted into the hole 240 disposed inside the corresponding elongated wall portion 220 in the width direction, the present invention is not limited thereto. Specifically, the connector 100 can be improved as follows: the first press-fit portion 460 is disposed at the end of the second extension portion 440; the first press-fit portion 460 of each row of first terminals 400 is held in the width direction by a retaining portion disposed outside the corresponding elongated wall portion 220.

[0164] Although the connector 100 in the above embodiment is configured such that the second press-fit portion 560 is provided at the second extension portion 540, and the second press-fit portion 560 of each row of second terminals 500 is press-fitted into the second retaining portion 282 in the width direction, the second retaining portion 282 being provided inside the corresponding elongated wall portion 220, the present invention is not limited thereto. Specifically, the connector 100 can be improved as follows: the second press-fit portion 560 is provided at the first extension portion 520; the second press-fit portion 560 of each row of second terminals 500 is held in the width direction by a retaining portion provided outside the corresponding elongated wall portion 220.

[0165] Although the first mounting portion 470 of the above embodiment extends outward from the second extension portion 440 in the width direction, the present invention is not limited thereto. Specifically, the first mounting portion 470 may extend inward from the first extension portion 420 in the width direction. As described above, the second extension portion 440 is provided with a locking portion 444. Furthermore, in a specific case where the connector 100 mounted on the circuit board 750 is removed from the mating connector 800, a force pointing in a direction away from the circuit board 750 is applied from the mating locking portion 827 to the locking portion 444. However, in a specific case, since the first mounting portion 470 fixed to the circuit board 750 extends from the second extension portion 440, the first mounting portion 470 of this embodiment can resist the force applied to the locking portion 444 and firmly fix the first terminal 400 to the circuit board 750. Therefore, the first mounting portion 470 of this embodiment is more preferred.

[0166] Although the second mounting portion 570 of the above embodiment extends inward from the second extension portion 540 in the width direction, the present invention is not limited thereto. Specifically, the second mounting portion 570 may extend outward from the first extension portion 520 in the width direction. As described above, the second extension portion 540 is provided with a locking portion 544. Furthermore, in certain cases, a force pointing in a direction away from the circuit board 750 is applied from the mating locking portion 857 to the locking portion 544. However, in certain cases, since the second mounting portion 570 fixed to the circuit board 750 extends from the second extension portion 540, the second mounting portion 570 of this embodiment can resist the force applied to the locking portion 544 and firmly fix the second terminal 500 to the circuit board 750. Therefore, the second mounting portion 570 of this embodiment is more preferred.

[0167] Although the first terminal 400 in the above embodiment is configured such that the position of the second contact point 442 does not overlap with the limiting portion 324 in the vertical direction, the present invention is not limited thereto. Specifically, the connector 100 can be improved so that the position of the second contact point 442 overlaps with the limiting portion 324 in the vertical direction. With this improvement, movement of the second contact point 442 relative to the insertion portion 300 becomes more difficult. Therefore, based on the completion of the mating of the improved connector 100 and the mating connector 800, the second contact point 442 of the first terminal 400 of the improved connector 100 can be positioned with higher accuracy relative to the mating first terminal 820 of the mating connector 800, and the set contact force between the mating terminal 820 and the second contact point 442 is more easily obtained.

[0168] Although the second terminal 500 in the above embodiment is configured such that the position of the second contact point 542 does not overlap with the limiting portion 324 in the vertical direction, the present invention is not limited thereto. Specifically, the connector 100 can be improved so that the position of the second contact point 542 overlaps with the limiting portion 324 in the vertical direction. With this improvement, it is more difficult to move the second contact point 542 relative to the insertion portion 300. Therefore, based on the completion of the mating of the improved connector 100 and the mating connector 800, the second contact point 542 of the second terminal 500 of the improved connector 100 can be positioned with higher accuracy relative to the mating second terminal 850 of the mating connector 800, and it is easier to obtain the set contact force between the mating terminal 850 and the second contact point 542.

[0169] The above description describes the preferred embodiments of the present invention and the technical principles applied thereto. For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solutions of the present invention, without departing from the spirit and scope of the present invention, shall fall within the protection scope of the present invention.
