[0006] The present invention provides a first connector, A connector that is mounted to a substrate when in use, the connector is vertically matable with a mating connector having a mating terminal, The connector includes a housing and a terminal. The terminal has a held portion, a supporting portion, a connecting portion, a contact point, and a terminal guide portion, The held portion is held by the housing, The support portion has elasticity, The connecting portion connects the held portion and the support portion to each other, The connecting portion has a fulcrum, The contact is supported by the support portion and faces a first orientation that is an orientation away from the held portion in a first horizontal direction perpendicular to the up-down direction, the terminal guide portion is located above the contact in the vertical direction, and extends in the first horizontal direction toward a second orientation that is an opposite orientation to the first orientation, and extends upward in the vertical direction; a specific contact position is a position where the mating terminal and the terminal guide portion come into contact with each other when the mating terminal moves on the terminal guide portion while pressing down the terminal as a whole during the mating of the mating connector and the connector, and the fulcrum begins to be pressed against one of the board and the housing; a force that the terminal guide portion receives from the mating terminal at the specific contact position and that is perpendicular to a contact surface between the mating terminal and the terminal guide portion is defined as a normal force; a friction force acting on the terminal guide portion due to friction between the mating terminal and the terminal guide portion when the mating terminal moves on the terminal guide portion at the specific contact position; When a point where an extension line of the resultant force of the normal force and the frictional force intersects with one of the substrate and the housing is taken as a reference point, The fulcrum is located on the first azimuth side of the reference point in the first horizontal direction. Provide a connector.

[0007] The present invention also provides a second connector, the first connector comprising: The fulcrum is located at the same position as the specific contact position or on the first azimuth side of the specific contact position in the first horizontal direction. Provide a connector.

[0008] The present invention also provides a third connector, which is the first or second connector, The terminal guide portion has a curved surface, The curved surface is located at the specific contact position. Provide a connector.

[0009] Furthermore, the present invention provides a fourth connector, which is any one of the first to third connectors, The housing has two connection guide surfaces, the two connection guide surfaces are located on both sides of the terminal guide portion in a second horizontal direction perpendicular to both the up-down direction and the first horizontal direction, Each of the connection guide surfaces extends within a plane defined by the vertical direction and the second horizontal direction, The terminal further includes a protruding portion, The protruding portion is formed at a boundary portion between the connecting portion and the supporting portion, When the connector and the mating connector are not yet mated, the protruding portion protrudes toward the first orientation or bulges toward the first orientation, In the unfitted state, the contacts and the protruding portion are located on the first orientation side relative to the connection guide surface. Provide a connector.

[0010] The present invention also provides a fifth connector, which is the fourth connector, The fulcrum is located near the protruding portion and protrudes most downward in the vertical direction in the connecting portion, In the unfitted state, the fulcrum is located at the same position as the connection guide surface or on the first orientation side of the connection guide surface in the first horizontal direction. Provide a connector.

[0011] The present invention also provides a sixth connector, which is the fifth connector, When the connector is viewed from below in the up-down direction, the fulcrum is visible. Provide a connector.

[0012] The present invention also provides a seventh connector, which is any one of the fourth to sixth connectors, The terminal guide portion has a curved surface, The curved surface is located at the same position as the connection guide surface in the first horizontal direction. Provide a connector.

[0013] The present invention also provides an eighth connector, which is any one of the fourth to seventh connectors, The protruding portion is located on the first orientation side of the contact point in the first horizontal direction. Provide a connector. Effect of the Invention

[0014] As can be seen from Fig. 19 and Fig. 20, when the connector 900 is mated with the mating connector 950, the contact 917 is displaced from the initial state in the X direction toward the outside of the connector 900. In addition, when the mating terminal 952 presses the terminal guide portion 918 in the -Z direction during mating between the connector 900 mounted on a rigid board and the mating connector 950, the connecting portion 914 hits the board, and the support portion 916 is elastically deformed with the hitting point as a fulcrum. At this time, a moment toward the inside of the connector 900 in the X direction is generated in the contact 917. That is, the connector 900 of Patent Document 1 has a problem in that the direction in which the contact 917 should be displaced from the initial state and the direction of the moment generated in the contact 917 when the connector 900 is mated with the mating connector 950 are opposite to each other.

[0015] On the other hand, in the connector of the present invention, the contact is supported by an elastic support portion, and faces a first orientation, which is an orientation away from the held portion, in a first horizontal direction perpendicular to the up-down direction. That is, in the connector of the present invention, the orientation to which the contact should be displaced from the initial state is a second orientation, which is the opposite orientation to the first orientation. Also, in the connector of the present invention, the fulcrum is located on the first orientation side of the reference point in the first horizontal direction. As a result, in the connector of the present invention, the moment at the specific contact position relative to the fulcrum is configured to face the second orientation, not the first orientation. For these reasons, in the connector of the present invention, the orientation to which the contact should be displaced from the initial state and the orientation of the moment at the specific contact position relative to the fulcrum are consistent. Therefore, in the connector of the present invention, the contact pressure between the mating terminal and the terminal does not increase when the connector is mated with the mating connector, and buckling of the terminal is avoided.

[0025] As shown in Fig. 2, each of the island-shaped portions 410 in this embodiment protrudes upward in the up-down direction. With reference to Figs. 2 and 8, when the connector 100 and the mating connector 700 are mated, the island-shaped portion 410 is accommodated in the island-shaped portion accommodating portion 724 of the mating connector 700. As shown in Fig. 11, the island-shaped portion 410 has a plurality of terminal accommodating portions 412 and a plurality of connection guide surfaces 420. That is, the housing 400 has a plurality of connection guide surfaces 420. Note that the present invention is not limited thereto, and the number of connection guide surfaces 420 may be two. That is, it is sufficient that the housing 400 has two connection guide surfaces 420.

[0026] As shown in Fig. 2, each of the terminal accommodating portions 412 in this embodiment opens downward in the up-down direction. As shown in Fig. 11, the terminal accommodating portions 412 open inward in the first horizontal direction. That is, the terminal accommodating portions 412 have an opening 413 located at the inner end in the first horizontal direction. The terminal accommodating portions 412 communicate with the protrusion accommodating portions 430 in the first horizontal direction via the opening 413. As shown in Fig. 2, each of the terminal accommodating portions 412 has a holding portion 414. That is, the housing 400 has a plurality of holding portions 414.

[0027] 2, the holding portions 414 in this embodiment are grooves located on both sides of the terminal accommodating portion 412 in the second horizontal direction.

[0028] 10, each of the connection guide surfaces 420 of the present embodiment extends within a plane defined by the vertical direction and the second horizontal direction. Each of the connection guide surfaces 420 is perpendicular to the first horizontal direction. The connection guide surfaces 420 are located on both sides of the opening 413 in the second horizontal direction.

[0029] 2, the protrusion accommodating portion 430 of the present embodiment is located between two island-shaped portions 410 in the first horizontal direction. As shown in Fig. 8, when the connector 100 and the mating connector 700 are mated, the protrusion accommodating portion 430 accommodates the protrusion 722 of the mating connector 700.

[0030] 11, each of the terminals 200 in this embodiment is made of metal. The terminals 200 are held in a housing 400. The terminals 200 are arranged in two rows in a first horizontal direction. The terminals 200 in each row are arranged in a second horizontal direction.

[0031] As shown in FIG. 13, the terminal 200 has a held portion 210, a support portion 260, a connecting portion 220, a contact point 270, a terminal guide portion 280, and a fixed portion 205.

[0032] As shown in Fig. 14, the held portion 210 in this embodiment extends in the vertical direction. As shown in Fig. 2, the held portion 210 is held by the housing 400. Specifically, the held portion 210 is held by the holding portion 414. The held portion 210 is press-fitted into the holding portion 414.

[0033] As shown in FIG. 14, the support portion 260 of this embodiment has elasticity. The support portion 260 extends upward in the up-down direction from the connecting portion 220. Specifically, the support portion 260 extends upward from the connecting portion 220 in the second direction, and then bends and extends upward in the first direction. In this embodiment, the first direction is a first horizontal inward direction, and the second direction is a first horizontal outward direction. Specifically, for the terminals 200 in the front row, the first direction is rearward, and the second direction is forward. Also, for the terminals 200 in the rear row, the first direction is frontward, and the second direction is rearward.

[0034] As shown in FIG. 14, the connecting portion 220 of this embodiment is a first connecting portion 220 extending from the held portion 210. horizontal The connecting portion 220 connects the held portion 210 and the support portion 260 to each other. The connecting portion 220 has a fulcrum 222.

[0035] As shown in Fig. 14, fulcrum 222 in this embodiment protrudes furthest downward in the vertical direction in connecting portion 220. Referring to Fig. 12, housing 400 does not have a bottom surface located directly below fulcrum 222. In other words, when connector 100 is viewed from below in the vertical direction, fulcrum 222 is visible. As a result, connector 100 in this embodiment has a lower height than a case in which housing 400 has a bottom surface located directly below fulcrum 222.

[0036] 2, the fulcrum 222 is movable downward in the up-down direction. When the connector 100 and the mating connector 700 are not mated with each other, the fulcrum 222 is located on the first orientation side of the connection guide surface 420 in the first horizontal direction. When the connector 100 and the mating connector 700 mounted on the board 800 are not mated with each other, the fulcrum 222 is not in contact with the board 800. As shown in FIG. 6, the fulcrum 222 comes into contact with the board 800 when the connector 100 mounted on the board 800 is mated with the mating connector 700.

[0037] 14, the contact 270 in this embodiment is located at the upper end of the support portion 260. The contact 270 is supported by the support portion 260, and faces a first orientation that is an orientation away from the held portion 210 in a first horizontal direction perpendicular to the up-down direction. That is, the orientation to which the contact 270 should be displaced from its initial state is a second orientation that is an opposite orientation to the first orientation. As shown in FIG. 2, in the unmated state between the connector 100 and the mating connector 700, the contact 270 is located on the first orientation side of the connection guide surface 420.

[0038] As shown in Fig. 14, the terminal guide portion 280 of this embodiment is located above the contact 270 in the vertical direction. The terminal guide portion 280 extends in a first horizontal direction toward a second direction that is an opposite direction to the first direction, and also extends upward in the vertical direction. As shown in Fig. 10, the two connection guide surfaces 420 are located on both sides of the terminal guide portion 280 in a second horizontal direction that is perpendicular to both the vertical direction and the first horizontal direction. The terminal guide portion 280 has a curved surface 282.

[0039] 14, the curved surface 282 of the present embodiment has an R-shape that bulges upward and inward in the first horizontal direction. As shown in Fig. 2, the curved surface 282 is located at the same position as the connection guide surface 420 in the first horizontal direction.

[0040] As shown in FIG. 14, the fixed portion 205 of the present embodiment defines the first horizontal outer end of the terminal 200. The fixed portion 205 defines the lower end of the terminal 200 in the up-down direction. As shown in FIG. 11, the fixed portion 205 is P It is fixed to head 810.

[0041] 14, the terminal 200 further has an overhanging portion 242. The overhanging portion 242 is formed at a boundary portion 240 between the connecting portion 220 and the support portion 260. The overhanging portion 242 is located on the first orientation side of the contact point 270 in the first horizontal direction. The fulcrum 222 is located on the second orientation side of the overhanging portion 242 in the first horizontal direction. The fulcrum 222 is located in the vicinity of the overhanging portion 242.

[0042] 2, in an unmated state between the connector 100 and the mating connector 700, the protruding portion 242 bulges out toward the first orientation. In an unmated state between the connector 100 and the mating connector 700, the protruding portion 242 is located on the first orientation side relative to the connection guide surface 420.

[0043] The force applied to the terminals 200 and the moment generated in the terminals 200 when the connector 100 mounted on the board 800 is mated with the mating connector 700 will be described in detail below.

[0044] First, the connector 100 and the mating connector 700 are arranged as shown in Fig. 2. When the mating connector 700 is moved from this state so that the connector 100 and the mating connector 700 approach each other in the vertical direction, the mating terminals 710 come into contact with the terminal guide portions 280 of the terminals 200, and the mating of the connector 100 and the mating connector 700 begins.

[0045] In this state, when the mating connector 700 is further moved so that the connector 100 and the mating connector 700 approach each other further in the vertical direction, the mating terminal 710 moves over the terminal guide portion 280 while pushing down the terminal 200 as a whole, and the fulcrum 222 begins to be pressed against the board 800, resulting in the specific contact state shown in Figures 5 and 6.

[0046] In this specific contact state, a position where the mating terminal 710 and the terminal guide portion 280 come into contact with each other is referred to as a specific contact position SP. At this time, the curved surface 282 of the terminal guide portion 280 of the terminal 200 is located at the specific contact position SP.

[0047] That is, when the mating connector 700 and the connector 100 are in the middle of mating, the mating terminal 710 moves on the terminal guide portion 280 while pressing down the terminal 200 as a whole, and the fulcrum 222 begins to be pressed against the board 800, the mating terminal 710 and the terminal guide portion 280 are in contact at the specific contact position SP.

[0048] In this specific contact state, the terminal guide portion 280 receives a force from the mating terminal 710 that is perpendicular to the contact surface between the mating terminal 710 and the terminal guide portion 280. This perpendicular force is referred to as a normal force VF. That is, at the specific contact position SP, the terminal guide portion 280 receives a normal force VF from the mating terminal 710, which is a force perpendicular to the contact surface between the mating terminal 710 and the terminal guide portion 280.

[0049] In addition, in the specific contact state, the terminal guide portion 280 is subjected to a force due to friction between the mating terminal 710 and the terminal guide portion 280. This frictional force is referred to as a frictional force FF. That is, in the specific contact position SP, the terminal guide portion 280 is subjected to the frictional force FF, which is a force due to friction between the mating terminal 710 and the terminal guide portion 280 when the mating terminal 710 moves on the terminal guide portion 280.

[0050] To summarize the above, in the specific contact state, the terminal guide portion 280 receives a resultant force JF of the normal force VF and the frictional force FF. Here, the point where an extension line EL of the resultant force JF intersects with the board 800 is defined as a reference point RP.

[0051] In the specific contact state, the fulcrum 222 is located on the first orientation side of the reference point RP in the first horizontal direction. More specifically, in the specific contact state, the fulcrum 222 is located in the same position as the specific contact position SP or on the first orientation side of the specific contact position SP in the first horizontal direction.

[0052] As described above, in the specific contact state, the terminal guide portion 280 receives the resultant force JF, and the fulcrum 222 is located on the first orientation side of the reference point RP in the first horizontal direction. As a result, referring to Fig. 12, a moment M that moves the terminal guide portion 280 in the second orientation around the fulcrum 222 is generated at the specific contact position SP. That is, in the connector 100 of this embodiment, the moment M at the specific contact position SP with respect to the fulcrum 222 is configured to face the second orientation.

[0053] As described above, the orientation in which the contact 270 should be displaced from its initial state is the second orientation, and at the specific contact position SP, a moment M is generated that moves the terminal guide portion 280 in the second orientation around the fulcrum 222. For these reasons, in this embodiment, the orientation in which the contact 270 should be displaced from its initial state coincides with the orientation of the moment M at the specific contact position SP relative to the fulcrum 222. Therefore, unlike the connector 900 of Patent Document 1, in the connector 100 of this embodiment, the contact pressure between the mating terminal 710 and the terminal 200 does not increase when the connector 100 is fitted to the mating connector 700, and buckling of the terminal 200 is avoided.

[0054] Although the present invention has been specifically described above with reference to the embodiment, the present invention is not limited to this and various modifications are possible.

[0055] Although the housing 400 of the connector 100 in the above-described embodiment does not have a bottom surface located directly below the fulcrum 222 of the terminal 200, the present invention is not limited to this. That is, the connector 100 may be modified so that the housing 400 has a bottom surface located directly below the fulcrum 222 of the terminal 200. In the case of this modification, the fulcrum 222 of the terminal 200 contacts the bottom surface of the housing 400 of the connector 100 when the connector 100 mounted on the board 800 and the mating connector 700 are fitted together. That is, the specific contact position SP in this modification is a position where the mating terminal 710 and the terminal guide portion 280 come into contact with each other when the mating terminal 710 moves on the terminal guide portion 280 while pushing down the terminal 200 as a whole and the fulcrum 222 starts to be pressed against the housing 400 during the mating of the mating connector 700 and the connector 100. Further, in this modified example, the reference point RP is a point where an extension line EL of the resultant force JF intersects with the housing 400. Note that in this modified example as well, the fulcrum 222 needs to be located on the first orientation side of the reference point RP in the first horizontal direction. As a result, in this modified example as well, as in the above-described embodiment, the orientation in which the contact 270 should be displaced from the initial state can be made to coincide with the orientation of the moment M at the specific contact position SP with respect to the fulcrum 222, so that the contact pressure between the mating terminal 710 and the terminal 200 does not increase when mating with the mating connector 700, and buckling of the terminal 200 can be avoided.

[0056] In the above embodiment, in the unfitted state of the connector 100 and the mating connector 700, the fulcrum 222 is located on the first orientation side of the connection guide surface 420 in the first horizontal direction. However, the present invention is not limited to this, and in the unfitted state of the connector 100 and the mating connector 700, the fulcrum 222 may be located at the same position as the connection guide surface 420 in the first horizontal direction. That is, in the unfitted state of the connector 100 and the mating connector 700, the fulcrum 222 may be located at the same position as the connection guide surface 420 or on the first orientation side of the connection guide surface 420 in the first horizontal direction. As a result, the fulcrum 222 contacts the board 800 at a relatively early stage during the mating of the connector 100 and the mating connector 700, and the desired moment M is generated at the specific contact position SP of the terminal 200, so that the buckling of the terminal 200 can be reliably prevented. This effect can also be enjoyed in the above-mentioned modified example.

[0057] In the above embodiment, the overhanging portion 242 bulges in the first direction when the connector 100 and the mating connector 700 are not mated, but the present invention is not limited thereto. The overhanging portion 242 may overhang in the first direction when the connector 100 and the mating connector 700 are not mated. That is, when the connector 100 and the mating connector 700 are not mated, the overhanging portion 242 may overhang in the first direction or bulge in the first direction. This makes it possible to make the terminal 200 less likely to buckle, since the support portion 260 of the terminal 200 pressed down by the mating terminal 710 can easily fall in the second direction when the connector 100 and the mating connector 700 are mated. This effect can also be enjoyed in the above-mentioned modified example. [Explanation of symbols]
