Description

  The present invention relates to a connector device including two connectors that can be fitted to each other.

  An example of this type of connector device is disclosed in Japanese Patent Laying-Open No. 2006-190685. The conventional connector structure disclosed here will be briefly described with reference to FIGS.

  The connector device includes a receptacle connector 82 shown in FIG. 26 and a connector assembly 81 shown in FIG. These are detachably fitted and electrically connected to each other.

  The receptacle connector 82 in FIG. 26 mainly includes a receptacle housing 96 and a plurality of contacts (not shown) provided on the receptacle housing 96. These contacts are provided in a plurality of contact cavities 97 (here, five of 97a to 97e) protruding in a cylindrical shape.

  Similarly, the connector assembly 81 shown in FIG. 27 mainly includes a connector housing 86 and a plurality of contacts 91 provided on the connector housing 86. Each contact 91 is provided in a cantilever shape toward the front fitting end 87 along the fitting direction (the arrow “A” direction in the drawing). All of the plurality of contacts 91 have substantially the same dimensions and configuration, and are further configured as a pair of two terminals 91a and 91b arranged to face each other. The terminals 91a and 91b constituting each set have contact portions 93a and 93b that are convexly curved outward along the facing direction (the direction of the arrow “A” in the figure), respectively. Further, a plurality of these sets are arranged in parallel along a direction (arrow "U" direction shown in the figure) orthogonal to both the fitting direction (arrow "A" direction shown in the figure) and the opposite direction (arrow "A" direction shown in the figure). As a result, a group 92 is formed. Five groups 92 (92a to 92e) are provided here corresponding to the number of contact cavities 97 of the receptacle housing 96, and a plurality of groups 92 are arranged in parallel along the opposing direction (the arrow “A” direction in the figure). ing.

  The receptacle connector 82 of FIG. 26 and the connector assembly 81 of FIG. 27 can be fitted to each other by inserting a contact cavity 97 provided in the receptacle connector 82 into a front fitting end 87 provided in the connector assembly 81. At this time, the contact 91 of the connector assembly 81 is inserted into the insertion hole 94 of the contact cavity 97, and the contact 91 of the connector assembly 81 and the contact of the receptacle connector 82 come into contact with each other.

JP 2006-190685 A

  However, in this conventional connector structure, in the fitting direction of the connector assembly 81 and the receptacle connector 82 (in the direction of the arrow “A” in the figure), the terminals 91a and 91b constituting each set of the contacts 91, particularly the contact portions 93a, 93b are all positioned equidistant from the receptacle connector 82, so that when the connector assembly 81 and the receptacle connector 82 are fitted together, the receptacle connector 82 (the contact cavity 97) is simultaneously released from all these terminals. As a result, the force required for insertion / extraction increased and the usability was poor.

  Moreover, in this conventional structure, since the terminals 91a and 91b have substantially the same dimensions and configuration, in order to prevent the terminals from colliding with each other when the terminals are displaced, a predetermined size is provided between them. As a result, the size of the apparatus has to be increased in order to ensure a sufficient amount of displacement.

  Further, when the connector assembly 81 and the receptacle connector 82 are fitted, the receptacle housing 96 of the receptacle connector 82 is inserted into the front fitting end 87 provided on the housing 86 of the connector assembly 81. Since the clearance of the housing is small, it is not possible to tolerate the misalignment sufficiently.As a result, there is a risk that the housing will interfere and be destroyed due to the forced mating with the misalignment. It was. Further, when the fitting is performed in a misaligned state, a load is still applied to the housing, and there is a problem that solder cracks or the like are likely to occur particularly in the mounting terminal portion.

  The present invention has been made to solve the above-described problems, and an object thereof is to reduce the insertion force when the connector is fitted. Another object of the present invention is to reduce the size of the device while ensuring a sufficient amount of terminal displacement. Furthermore, it aims at providing the connector apparatus which raised the tolerance of the fitting gap.

A first type terminal and a second type terminal arranged in a cantilever shape and facing each other, wherein the second connector includes a housing and a contact member provided in the housing; Each of the one type terminal and the second type terminal has a contact portion that is convexly curved outward along the facing direction, and when the first connector and the second connector are fitted, the contact portion is Each of the first type terminal and the second type terminal is displaced inward along the opposing direction by elastic contact with the contact member of the second connector, respectively. The contact portion of the second type terminal is disposed at a position closer to the second connector in the fitting direction than the contact portion of the first type terminal. When the second type terminal and the second type terminal are displaced inward along the facing direction, the vicinity of the tip of the contact portion of the first type terminal is It is characterized by escaping into the concave curved space formed in the direction.

  In the connector device, a plurality of sets of the first type terminals and the second type terminals may be arranged in parallel along a direction orthogonal to both the fitting direction and the facing direction.

  Further, in the connector device, all the contact parts of the first type terminals are positioned at an equal distance from the second connector in the fitting direction, and all the contact parts of the second type terminals are In the fitting direction, it may be positioned equidistant from the second connector.

  Further, in the connector device, the number of the first type terminals or the second type terminals arranged along the orthogonal direction on one opposite side, and the orthogonal direction on the other opposite side. The number of the second type terminals or the first type terminals arranged along the line is preferably balanced, for example equal.

  In the connector device, when the first connector and the second connector are fitted, the second connector is near the tip of the first type terminal of the first connector or the first connector of the first connector. The first connector may be guided by elastic contact with the vicinity of the tip of the two types of terminals.

In the connector device, the housing of the first connector is provided with one fitting hole into which a plurality of fitting protrusions provided in the housing of the second connector are inserted, and the plurality of fitting protrusions. Corresponding to the portion, the fitting hole has a terminal group formed by arranging a plurality of pairs of the first type terminal and the second type terminal in parallel along the orthogonal direction. A plurality of them may be arranged in parallel along the facing direction.
In the connector device, the terminal may include a power supply terminal.
Further, the present invention is a connector device comprising a first connector and a second connector that can be fitted to the first connector, wherein the first connector is provided at least in a housing and the housing. Two displaceable terminals of the same size and shape, the at least two terminals being cantilevered along the mating direction in the housing, and in the mating direction and the The second connector has a housing and a contact member provided on the housing, and is disposed opposite to each other along a direction orthogonal to both of the displacement directions. Each of the terminals has a contact portion that is convexly curved outward along the displacement direction, and when the first connector and the second connector are fitted, the contact portions are respectively connected to the second connector. By the elastic contact with the contact member, each of the at least two terminals is displaced inward along the displacement direction, and the contact portions are all in the second direction in the fitting direction.

One preferred embodiment of the present invention will be described with reference to the drawings.
1. Overall Structure FIG. 1 is a perspective view showing an example of a contact device 10 according to the present invention. The contact device 10 mainly includes a receptacle connector 20 and a plug connector 60. These are detachably fitted and electrically connected to each other.

  The receptacle connector 20 mainly includes a receptacle housing 21 and a receptacle contact member 30 provided on the receptacle housing 21. The contact member 30 is used in a fixed state by soldering to the substrate 11, for example.

The plug connector 60 mainly includes a plug housing 61 and a plug contact member 70 provided on the plug housing 61. The contact member 70 is used in a fixed state by soldering to the substrate 12, for example.
Note that both the receptacle connector 20 and the plug connector 60 may be fixed to the substrate by, for example, press fitting without using solder, or may be fixed by pressure bonding.

  The plug housing 61 of the plug connector 60 further includes a base body 62 and a plurality of cylindrical fitting protrusions 63 provided on the base body 62. When the receptacle connector 20 and the plug connector 60 are fitted, the fitting protrusion 63 of the plug connector 60 is inserted into one fitting hole 23 of the receptacle connector 20, and at the same time, the insertion hole 64 of the fitting protrusion 63 is inserted. In particular, the terminal portions of the contact member 30 (parts 41, 42, 51, 52, etc. shown in FIGS. 3, 4, etc.) are inserted. These terminals may include a power supply terminal. The wall 24 that partitions the fitting hole 23 is for preventing a user's finger or the like from touching the contact member 30, and maintains the fitting state or fitting of the fitting protrusion 63. It is not intended to invite you to the hole 23. Therefore, it goes without saying that the wall portion 24 may not be provided and the fitting hole connected to one may be used.

  Each terminal (41, 42, 51, 52, etc. shown in FIG. 3, FIG. 4, etc.) is urged in the insertion hole 64, whereby the terminal and the insertion hole 64 (for example, the contact member 70 provided therein). Between the receptacle connector 20 and the plug connector 60 is maintained. Note that the plug housing 61 of the plug connector 60 is merely loosely fitted into the receptacle housing 21 of the receptacle connector 20. Rather, in this apparatus, the housing clearance is relatively large, for example, ± 0. It is set to 5 mm. In order to prevent an error in the insertion direction of the plug connector 60 with respect to the receptacle connector 20, an erroneous insertion prevention key 65 may be provided on the plug connector 60. Corresponding to the erroneous insertion prevention key 65, an erroneous insertion prevention portion 25 is provided on the receptacle connector 20 side.

  FIG. 2 is a perspective view showing another example of the contact device 10 ′. The same reference numerals are used for the same members as in FIG. 1, and “′” is attached for convenience. The basic configuration of the contact device 10 'is the same as that of FIG. The substantial difference is only the installation direction of the receptacle connector 20 'and the plug connector 60' with respect to the board 11 'and the board 12' and the fitting direction related thereto. That is, in the example of FIG. 1, the fitting hole 23 of the receptacle connector 20 is opened horizontally with respect to the board 11, and the insertion hole 64 of the plug connector 60 is opened horizontally with respect to the board 12, respectively. In addition, the receptacle connector 20 and the plug connector 60 are fitted so that the substrate surfaces of the substrates 11 and 12 are close to each other. On the other hand, in the example of FIG. 2, the fitting hole 23 ′ of the receptacle connector 20 ′ is perpendicular to the board 11 ′, and the insertion hole 64 ′ of the plug connector 60 ′ is perpendicular to the board 12 ′. In addition, the receptacle connector 20 ′ and the plug connector 60 ′ are fitted so that the edges of the substrates 11 ′ and 12 ′ are close to each other. In the configuration of FIG. 2, as shown in FIG. 1, the contact member 30 ′ and the contact member 70 ′ are directly soldered to the substrates 11 ′ and 12 ′, and are fixed to the substrate using the reinforcing metal fitting 13.

  It should be noted that the examples shown in FIGS. 1 and 2 do not limit the combination method. The combination can be freely changed according to the situation. For example, the receptacle connector 20 of FIG. 1 and the plug connector 60 ′ of FIG. 2 can be combined, or the plug connector 60 of FIG. 1 and the receptacle connector 20 ′ of FIG. 2 can be combined.

2. Receptacle Connector The structure of the receptacle contact member 30 will be described in more detail with reference to FIGS. FIGS. 3A and 3B are perspective views showing the contact member 30 in different directions, respectively. 4A is a front view corresponding to FIG. 3A, FIG. 4B is a front view, FIG. 4C is a rear view, and FIG. 4D is a plan view.

  The contact member 30 is formed by punching and bending a single metal plate. In order to increase the reliability of contact, for example, gold plating is applied to the whole. The contact member 30 has a base 31 having a U-shape when viewed from above. The base 31 forms a single plate-like body that is bent at a seam 32 that connects one surface 46 and the other surface 47. A press-fit protrusion 34 that facilitates fixing to the receptacle housing 21 is provided on the lower edge of each of the one surface 46 and the other surface 47. Further, on the upper side of the base portion 31, a plurality of terminals 41 having elasticity and the like are arranged in a cantilever shape along the fitting direction (the arrow “A” direction in the drawing). On the other hand, a plurality (four in this case) of fixing portions 35 extend below the base portion 31. For example, by inserting the terminal side from the bottom of the receptacle housing 21 toward the fitting side, the contact member 30 is fixed to the contact member 30 using the press-fit protrusion 34 or the like.

  The contact member 30 is provided with a total of eight terminals. These terminals are short terminals 41, 41 ′, 42, 42 ′, which are “first type” terminals, and long terminals 51, 51 ′, 52, 52 ′, which are “second type” terminals. Can be classified. The short terminals 41, 41 ′, 42, 42 ′ are in the fitting direction from the base 31 (in the direction of the arrow “A” in FIGS. 1 and 3) as compared with the long terminals 51, 51 ′, 52, 52 ′. The length along is short. As for other configurations, there is substantially no difference between the two.

  Terminals 41, 41 ′, 42, 42 ′, 51, 51 ′, 52, 52 ′ form a total of four “sets”. That is, a set including short terminals 41 and 41 ', a set including long terminals 51 and 51', a set including short terminals 42 and 42 ', and a set including long terminals 52 and 52'. The terminals included in each set have the same dimensions and configuration. However, it is not always necessary to set the terminals in such a set, and one of the sets, for example, the short terminal 41 'can be removed. However, if a large number of terminals are provided to increase the contact structure, the cross-sectional area of the conductor increases (the resistance of the conductor decreases), and the contact stability can be improved. The terminals in each set are separated by providing a relatively short cut 38. For convenience, in the following description, one of the sets (the short terminal 41 ′, the long terminal 51 ′, the short terminal 42 ′, and the long terminal 52 ′) is not particularly described unless particularly described.

  In particular, the short terminal 41 constituting the first type and the long terminal 52 constituting the second type are opposed to each other along a certain direction (the arrow “I” direction in the figure, hereinafter referred to as “opposing direction”). The short terminal 42 constituting the first type and the long terminal 51 constituting the second type are arranged so as to face each other along the facing direction (the arrow “A” direction in the figure). This is important. The short terminal 41 and the long terminal 52, the short terminal 41 ′ and the long terminal 52 ′, the short terminal 42 and the long terminal 51, and the short terminal 42 ′ and the long terminal 51 ′ that are arranged to face each other form a “set”. ing. These sets are referred to as a direction orthogonal to both the fitting direction (shown arrow “A” direction) and the opposing direction (shown arrow “A” direction) (shown arrow “U” direction, hereinafter, simply “orthogonal direction”). ) Are arranged in parallel. The pair is separated by providing a relatively long cut 37.

  Here, on one side facing each other, a plurality of short terminals 41, 41 ′ arranged along the orthogonal direction (arrow “c” direction shown in the figure) and on the other side facing each other, they are arranged along the orthogonal direction. The plurality of short terminals 42, 42 ′ are all positioned at an equal distance from the mating plug connector 60 in the mating direction (the arrow “A” direction in the figure). Similarly, a plurality of long terminals 51, 51 ′ arranged along the orthogonal direction on one side facing each other, and a plurality of long terminals 52, 52 arranged along the orthogonal direction on the other side facing each other. 'Is all located at an equal distance from the mating plug connector 60 in the mating direction (in the direction of arrow “A” in the figure). With such an arrangement, the force received from these terminals can be effectively dispersed in the plug connector 60, particularly the insertion hole 64 of the plug connector 60.

  Furthermore, the number of short terminals or long terminals (here, the short terminals are 41, 41 ′) arranged along the orthogonal direction (the arrow “c” direction shown in FIGS. 1, 3 and 4) on one side facing each other. And two long terminals 51 and 51 ') and the number of long terminals or short terminals arranged along the orthogonal direction on the other side facing each other (here, the long terminals are 52 and 52'). The two short terminals 42 and 42 'are preferably balanced, for example, equal to each other (two short terminals and two long terminals here). Thereby, the force applied to the opposite one side and the force applied to the other opposing side can be made equal. The short terminals 41, 41 'and the short terminals 41, 41' each of the long terminals 51, 51 'and the long terminals 52, 52' may consist of only one, or an unbalanced arrangement, for example on one side It goes without saying that any of the terminals may be more.

  For the same reason, the short terminals or long terminals arranged along the orthogonal direction on one side facing each other and the long terminals or short terminals arranged along the orthogonal direction on the other side facing each other are , Preferably in a point control. For example, in the illustrated example, the short terminal 42 ′ with respect to the short terminal 41, the short terminal 42 with respect to the short terminal 41 ′, and the long terminal 51 ′ with respect to the long terminal 52 become the long terminal 52 ′. On the other hand, the long terminals 51 are respectively arranged in point contrast.

The terminals 41, 42, 51, 52 are arranged outwardly in the opposite direction (the direction of the arrow “A” in the figure) (the counterpart terminal (for example, the counterpart terminal of the short terminal 41 is the long terminal 52, and the counterpart terminal of the short terminal 42 is On the side away from the long terminal 51, the mating terminal of the long terminal 51 is the short terminal 42, and the mating terminal of the long terminal 52 is the short terminal 41), each of which has convex curved portions 41A, 42A, 51A, 52A. .
When the receptacle connector 20 and the plug connector 60 are fitted, the convex curved portions 41A, 42A, 51A, 52A are in elastic contact with the contact members 70 in the insertion holes 64 of the plug connector 60, respectively. As a result, the short terminals 41 and the long terminal 52, or the short terminal 42 and the long terminal 51 are respectively inward (mating terminals (e.g. 52, the counterpart terminal of the short terminal 42 is displaced to the long terminal 51, the counterpart terminal of the long terminal 51 is the short terminal 42, and the counterpart terminal of the long terminal 52 is the short terminal 41).
As described above, since the short terminals 41 and 42 are set to have a shorter length in the fitting direction from the base portion 31 (arrow “A” direction in the drawing) than the long terminals 51 and 52, the long terminals 41 and 42 are long. The contact parts 52A and 51A of the terminals 52 and 51 are arranged closer to the plug connector 60 in the fitting direction than the contact parts 41A and 42A of the short terminals 41 and 42. As a result, the contact portions 41A and 42A of the short terminals 41 and 42 and the contact portions 52A and 51A of the long terminals 52 and 51 are inward (approaching the mating terminal) along the opposing direction (the arrow “A” direction in the figure). When the contact portions 41A, 42A of the short terminals 41, 42 are displaced toward the tip side 41C, 42C, the concave curved spaces 52C formed inward by the contact portions 52A, 51A of the long terminals 52, 51, Since it is accommodated in 51C, it does not collide with the long terminals 52 and 51. With such a configuration, the amount of displacement of the terminal is sufficiently secured, while the device is downsized.

3. An example of the plug connector plug contact member 70 is shown in FIG. FIGS. 5A and 5B are perspective views showing the contact member 70 in different directions, and correspond to FIGS. 3A and 3B, respectively.

  Similar to the contact member 30, the contact member 70 is formed by punching and bending a single metal plate. In order to increase the reliability of contact, for example, gold plating is applied to the whole. The contact member 70 has a base 71 having a U-shape when viewed from above. The base 71 forms a single plate that is bent at a joint 72 that connects one surface 76 and the other surface 77. A press-fit protrusion 74 that facilitates fixing to the plug housing 61 is provided on the lower edge of each of the one surface 76 and the other surface 77. A plurality (four in this case) of fixing portions 75 extend below the base portion 71. For example, the contact member 70 is inserted into the plug housing 61 from the head side, and is fixed thereto using the press-fitting protrusion 74 or the like. The contact member 70 contacts and is electrically connected to the short terminals 41 and 42 and the long terminals 51 and 52 when the receptacle connector 20 and the plug connector 60 are fitted.

4). Operation etc. FIG. 6 is a diagram showing an overview of the connector device 10, wherein (a) is a front view thereof and (b) is a left side view thereof.
7 is a cross-sectional view taken along line II in FIG. 6B, and FIG. 8 is a cross-sectional view taken along line II-II in FIG. 6B. For convenience, the short terminal 41 and the long terminal 52 are shown. 9 is a sectional view taken along the line II-II in FIG. 6B, and FIG. 10 is a sectional view taken along the line III-III in FIG. 6A. In particular, 10 indicates a state before the receptacle connector 20 and the plug connector 60 are fitted together.
On the other hand, FIGS. 11 to 14 are cross-sectional views corresponding to FIGS. 7 to 10, respectively, showing a state in the middle of fitting of the receptacle connector 20 and the plug connector 60, and FIGS. FIG. 18 is a cross-sectional view corresponding to each of FIGS. 7 to 10, showing a state where the receptacle connector 20 and the plug connector 60 are further fitted, and FIGS. 19 to 22 are diagrams. FIG. 11 is a cross-sectional view corresponding to each of FIGS. 7 to 10, showing a state in which the receptacle connector 20 and the plug connector 60 have been fitted.

  When the receptacle connector 20 and the plug connector 60 are fitted, a plurality of fitting protrusions 63 provided on the plug connector 60 are inserted into the fitting holes 23 of the receptacle connector 20. Corresponding to the plurality of fitting protrusions 63, the fitting hole 23 has a terminal group 54 consisting of eight terminals included in each contact member 30, that is, in the fitting direction (the arrow “A” direction in the figure). A pair of a short terminal 41 and a long terminal 52, a pair of a short terminal 41 ′ and a long terminal 52 ′, a pair of a short terminal 42 and a long terminal 51, and a short terminal 42, which are disposed so as to face each other in a cantilever manner. A terminal group 54 formed by arranging a plurality of sets of 'and long terminals 51' in parallel along the orthogonal direction (arrow "U" direction in the figure) is arranged in the opposite direction (arrow "I" direction in the figure). ) (In this case, five of the terminal groups 54a to 54e) are arranged in parallel and inserted simultaneously. Here, since the terminal groups 54a to 54e have the same configuration, the plug connector 60 efficiently receives the same force from each of the terminal groups 54a to 54e in a distributed manner.

  The state shown in FIGS. 11 to 14 is the state where the contact on one side is displaced from the state before the fitting shown in FIGS. 7 to 10, more specifically, only the long terminals 51 and 52 are in contact with the contact member 70. The short terminals 41 and 42 are not in contact with the contact member 70 yet.

  In each terminal group 54a-54e, since the long terminals 51 and 52 are arrange | positioned in the same position in a fitting direction, they contact the contact member 70 at the same timing. In this way, by making contact at the same timing, the force applied to the contact member 70 by the long terminals can be efficiently dispersed without concentrating them, and, as in the present embodiment, these long terminals 51 and When the same number of the long terminals 52 are arranged for point contrast, the contact member 70 (each fitting protrusion 63) receives a force evenly distributed.

  Furthermore, since the short terminals 41 and 42 are positioned farther from the plug connector 60 than the long terminals 51 and 52 in the fitting direction (indicated by the arrow “A” in the figure), the short terminals 41 and 42 come into contact with each other. It comes into contact with the contact member 70 (which is well shown in FIGS. 15 to 18 described later), and as a result, the force received by the contact member 70 can be efficiently dispersed. The device 10 thus has a two-stage contact timing terminal structure that reduces the insertion force.

  Further, as well shown in FIGS. 11 to 13, when the receptacle connector 20 and the plug connector 60 are fitted, the plug connector 60 is located near the tip 41 </ b> A of the short terminal 41 of the receptacle connector 20, or of the receptacle connector 20. By being in elastic contact with the vicinity of the tip 52A of the long terminal 52, it is easily drawn into the receptacle connector 20. For example, it is preferable to set the tip 41A of the short terminal 41 and the tip 52A of the long terminal 52 to be relatively long so that, for example, a fitting shift of 0.5 mm on one side can be absorbed. As described above, since the plug housing 61 of the plug connector 60 is merely loosely fitted into the receptacle housing 21 of the receptacle connector 20, such a lead-in by the terminal is very effective for the apparatus 10. .

The state shown in FIGS. 15 to 18 further advances from the state shown in FIGS. 11 to 14 and the contact points on both sides are displaced, that is, not only the long terminals 51 and 52 but also the short terminals 41 and 52. 42 also shows a state in which the contact member 70 is elastically displaced in contact with the contact member 70.
Even in such a case, in this apparatus 10, the tips 41C and 42C of the contact portions 41A and 42A of the short terminals 41 and 42 are concavely formed inwardly of the contact portions 52A and 51A of the long terminals 52 and 51. Since they are accommodated in the spaces 52C and 51C, the short terminals 41 and 42 and the long terminals 52 and 51 do not interfere with each other. With this configuration, it is possible to design a compact spring while ensuring a sufficient amount of displacement or displacement region for each terminal. This configuration is useful for reducing the size of the apparatus.

5. Lastly, with reference to FIGS. 23 to 25, the allowable effect of misalignment at the time of fitting will be described. 23 to 25 are views showing a state in which the plug housing 61 of the plug connector 60 and the receptacle housing 21 of the receptacle connector 20 are misaligned. In particular, FIGS. 23 and 24 are respectively the above-described FIGS. FIG. 25 corresponds to FIG. 10 described above.

  As described above, in the present apparatus 10, the plug housing 61 of the plug connector 60 is merely loosely fitted to the receptacle housing 21 of the receptacle connector 20, and the outer side of the terminal 41 and the like is included. Since the fitting state between the receptacle connector 20 and the plug connector 60 is maintained using the elastic force toward the connector, even if the housings are slightly misaligned, the elastic force of the terminal 41 or the like is used, They can be easily fitted. That is, according to this configuration, at the time of mating, and further after mating, the elastic force of the terminal 40 is used to absorb the misalignment and the plug connector 60 returns to the center of the receptacle connector 20. It can be corrected. Further, by allowing such positional deviation, it is possible to prevent the housings from interfering with each other, so that the housing can be effectively prevented from being destroyed. Furthermore, no load due to interference is generated, and no solder cracks are generated.

The above example describes an example in which two types of terminals, that is, a first type terminal such as the short terminals 41 and 42 and a second type terminal such as the long terminals 51 and 52 are provided. Even when only one type of terminal is provided, the object of the present invention is achieved, for example, the object of the present invention is achieved such that the amount of displacement of the terminal is sufficient while the device is downsized. can do.
For reference, an example in which only the long terminals 51 and 52 are provided will be described below with reference to FIGS. 3, 4, 11, and 12. These two long terminals 51 and 52 are connected to the housing 21 in a direction (arrow “U” direction shown in the figure) orthogonal to both the fitting direction (arrow “A” direction in the figure) and the displacement direction (arrow “A” direction in the figure). It can be said that they are opposed to each other while being shifted from each other. When the receptacle connector 20 and the plug connector 60 are fitted, the long terminals 51 and 52 are in elastic contact with the contact members 70 of the plug connector 60 at the contact portions 51A and 52A, respectively. Each of the terminals 51 and 52 is displaced inward along the displacement direction (the arrow “A” direction in the figure). The contact portions 52A and 51A are all located at an equal distance from the plug connector 60 in the fitting direction (the arrow “A” direction in the figure), but the long terminals 51 and 52 are orthogonal to the housing 21 (the arrow in the figure). Since the long terminals 51 and 52 are displaced, they do not collide with each other even when the long terminals 51 and 52 are displaced. Therefore, the device can be miniaturized while the amount of displacement of the terminal is sufficient.
