Description
Technical Field
The present invention relates to a floating connector.
Background
In the prior art, the following floating connectors are known: which is mounted with a mechanism (floating mechanism) for absorbing errors and deviations in the longitudinal and transverse directions that occur when the connector is mounted on a substrate (see, for example, patent document 1). By using the floating connector, it is possible to absorb errors and variations and prevent damage to the substrate itself.
In the floating connector of patent document 1, positional deviation is restricted by providing a projection and a side end portion of a housing at an insertion opening and its vicinity so that positional deviation of moment (rotation) caused by a force with which a connection object (mating connector) abuts against the connector does not increase when the connection object is inserted into the floating connector. This prevents the portion of the floating terminal (referred to as "contact" in patent document 1) located at the insertion opening of the second housing and the vicinity thereof from being significantly displaced and deformed by applying an excessive load, and prevents the fixed portion (referred to as "tine portion" in patent document 1) fixed to the substrate of the floating terminal from coming off under the load due to the positional deviation of the components.
However, although an excessive load due to the positional deviation is suppressed, since the positional deviation is restricted between the housings, problems such as low strength due to material arise, and there is a problem that the positional deviation cannot be stably restricted with sufficient strength.
Patent document 1: JP-Kokai JPH09-180829A
Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a floating type connector which suppresses an increase in positional deviation due to moment when a connection object is separated from a fixed position at which a reinforcing metal fitting is fixed on a substrate and a contact position of a housing even at the time of insertion of the connection object and after the completion of the insertion of the connection object, and which can stably restrict the positional deviation with sufficient strength even with a simple configuration without applying an excessive load to the housing and a floating terminal.

First embodiment
A floating connector 10 according to a first embodiment will be described below with reference to fig. 1 to 7. As shown in fig. 1, a floating type connector 10 according to a first embodiment is provided with: a cassette-type housing 20; a plurality of floating terminals 30 provided inside the housing 20; a pair of substrate fixing members 40 provided on both left and right sides of the exterior of the housing 20; and a floating terminal fixing member 50 fixed to the floating terminal 30 and the substrate fixing member 40 at the rear of the housing 20. A connection object S such as a substrate, a wire, or a substrate connector is embedded in parallel with the substrate Bd (the direction of the white frame arrow in the drawing) from the front surface side of the housing 20.
The components are explained with reference to fig. 2, 3, 4 and 7. The housing 20 has a housing fitting portion 21 formed therein, and the housing fitting portion 21 has a fitting opening 22 into which the connection object S is fitted and a receiving space 23 located behind the fitting opening 22 to receive the connection object S. The housing fitting portion 21 has tapered portions 21b at the upper, lower, left, and right sides, the tapered portions 21b are narrowed from the front face 21a toward the housing space 23 so as to introduce the connection object S, and the front face 21a and the tapered portions 21b are formed at the fitting opening 22. The tapered portion 21b continues to the seat portion 21c where the floating terminal 30 is provided.
The floating terminal 30 is formed of a plate-like member, and includes: a contact portion 31 that contacts the connection object S; a base end portion 33 fixed to the floating terminal fixing member 50; and an elastic portion 32 located between the contact portion 31 and the base end portion 33. Further, the base end portion 33 of the floating terminal 30 is located rearward of the root portion 31a of the contact portion 31. The contact portion 31 is divided into two strands which are disposed on the upper and lower seat portions 21c of the housing 20 and abut against the upper and lower surfaces of the connection object S. Note that fig. 2 shows only the seat portion 21c on the lower side, but the same seat portion 21c is also provided on the upper side and continues from the taper portion 21b on the upper side. The elastic portion 32 is formed in a C-shaped curved shape when viewed from the side of the plate-like member, and is thereby configured to be easily elastically deformed in the left-right direction (floating mechanism). The base end portion 33 is fixed to the floating terminal fixing member 50.
The pair of substrate fixing members 40 are each integrally molded from a high-strength member such as SUS (stainless steel) material, and each have: a substrate contact portion 41 fixed to the substrate Bd at the bottom surface; and a side restricting portion 42 for restricting the side movement of the housing 20. The bottom surface of the substrate contact portion 41 is fixed to the substrate Bd by soldering or the like. At this time, as shown in fig. 2, 3, and 4, the position of the side regulating portion 42 overlaps the entire position of the fitting opening 22 when viewed from the left and right sides of the connector 10. This restricts the movement of the housing 20 and the floating terminal 30 to the side of the insertion port 22 that naturally moves and swings to the left and right during floating, and also restricts the excessive load from acting on the housing and the floating terminal, and the board fixing member 40 that is integrally molded with a high-strength member can restrict the movement with sufficient strength. Fig. 3 and 4 show a positional relationship in which the side restriction portion 42 and the fitting opening 22 are positioned to entirely overlap, but the lateral movement of the fitting opening 22 may be restricted, and the positions of the side restriction portion 42 and the fitting opening 22 may be positioned so that at least a part of the side restriction portion 42 and the fitting opening 22 overlap when viewed from the left and right sides of the connector 10.
The board contact portion 41 is disposed below a position where the fitting opening 22 and the side restricting portion 42 overlap each other when viewed from the left and right sides of the connector 10. Thus, the substrate fixing member 40 is fixed to the substrate in the vicinity of the force received by the side restricting portion 42, whereby the action of the transmitted force can be reduced. The substrate contact portion 41 may be fixed in the vicinity of the force received by the side restriction portion 42, or at least a part of the substrate contact portion 41 may be provided below the position where the insertion port 22 overlaps the side restriction portion 42.
Further, the substrate fixing member 40 may be provided with: an upper limiting portion 43 extending toward the housing 20 on the upper side of the side limiting portion 42; and a front regulating portion 44 located at a front end of the upper regulating portion 43 and bent downward. The upper restriction portion 43 restricts upward movement of the housing 20, and the front restriction portion 44 restricts forward movement of the housing 20. The upper limiting portion 43 functions similarly to the above-described side limiting portion 42 with respect to the positional deviation of the upper side, and limits the positional deviation due to the upward moment with sufficient strength. The front regulating portion 44 can be integrally molded with the side regulating portion 42 and the upper regulating portion 43, and the number of components can be reduced by such molding.
The pair of substrate fixing members 40 may be configured to have a connecting portion 45 extending rearward on the rear side of the side restricting portion 42. The connection portion 45 is fitted into a through hole 52a formed in the side end portion 52 of the floating terminal fixing member 50, and thereby the substrate fixing member 40 is fixed to the floating terminal fixing member 50. Thereby, the substrate fixing member 40 can be appropriately positioned with respect to the insertion port 22 of the housing 20.
The floating terminal fixing member 50 is located behind the housing 20, and is provided with: a base 51 corresponding to the mounting width of the pair of substrate fixing members 40; and a pair of side ends 52 located at both ends of the base 51. A groove 53 for holding the base end 33 of the floating terminal 30 and a partition 54 for sandwiching the adjacent groove 53 are provided in the middle of the base 51. As described above, the connection portion 45 of the substrate fixing member 40 is fixed to the side end portion 52.
Further, the floating terminal fixing member 50 may be provided to have a rear restriction portion 55 at the front side of the base 51 (or in other words, at the rear surface side of the housing 20). The rear restriction portion 55 restricts the rearward movement of the housing 20. When configured in this manner, the floating terminal holding member 50 can properly position the substrate holding member 40, and can achieve the restriction of the floating of the connection object S in the embedding direction with one member. Further, the floating terminal fixing member 50 and the rear restriction portion 55 thereof are disposed at the rear of the housing 20 and thus do not overlap in position in the height direction, thereby successfully reducing the height of the connector.
Note that the housing 20 is formed in a rectangular parallelepiped shape as described above, but this shape is for illustrative purposes only, and the shape of the housing 20 is not limited to a rectangular parallelepiped shape. As other examples, the housing 20 may be formed of a curved surface such as a shape of a cylinder or an elliptic cylinder. In this case, the side regulating portion 42 of the substrate fixing member 40 may be a flat surface as described above, or may be a curved surface conforming to the shape of the housing 20. Note that the front restricting portion 44, the side restricting portion 42, and the upper restricting portion 43 may be formed in a shape matching the side shape of the housing for surface contact, and by doing so, the force due to the positional deviation is received by the surface, and thereby the floating can be stably restricted. For example, in the first embodiment, the housing is a rectangular parallelepiped, and therefore the planes are in contact with each other.
The operation of the floating connector 10 will be described based on the above-described configurations of the respective members with reference to fig. 5A to 7. The floating connector 10 is floatable in each of the left-right direction, the up-down direction, and the front-back direction, and has a restriction portion for each of these directions.
First, as shown in fig. 5A, in the left-right direction, the case 20 can float in the left-right direction (X-X' direction in the drawing) between the side restricting portions 42 of the pair of substrate fixing members 40 by utilizing the gaps C1 provided between the side restricting portions 42 of the pair of substrate fixing members 40 and the left and right side surfaces of the case 20.
For example, as shown in fig. 5A, when the connection object S is fitted in a state of being shifted in the right direction (X 'direction) with respect to the fitting opening 22 of the housing 20, as shown in fig. 5B, the housing 20 is floated in the right direction (X' direction) by the elastic deformation of the elastic portion 32 of the floating terminal 30 by the right side gap C1. Thus, the insertion port 22 and the housing 20 face the connection object S, and the connection object S is appropriately accommodated in the accommodation space 23. Further, when the user releases the connection object S, as shown in fig. 5C, the housing 20 floats in the left direction (X direction) in a state where the connection object S is fitted and returns to the center position (standard position).
Next, with respect to the vertical direction, as shown in fig. 6, the case 20 can float in the vertical direction (Z' -Z direction in the drawing) between the substrate Bd and the upper regulating portions 43 of the pair of substrate fixing members 40 by utilizing the gaps C2 provided between the upper regulating portions 43 of the pair of substrate fixing members 40 and the upper surface of the case 20, respectively.
For example, when the connection object S is fitted in a state of being offset in the upward direction (Z 'direction) with respect to the fitting opening 22 of the housing 20, the housing 20 is floated in the upward direction (Z' direction) by the elastic deformation of the elastic portion 32 of the floating terminal 30 by the gap C2. Thus, the insertion port 22 and the housing 20 face the connection object S, and the connection object S is appropriately accommodated in the accommodation space 23. Further, when the user releases the connection object S, the housing 20 floats downward (Z direction) in a state where the connection object S is fitted and returns to the standard position.
Next, the housing 20 is structurally divided into a front side and a rear side with respect to the front-rear direction. On the front side, as shown in fig. 6, the housing 20 is allowed to float in the front-rear direction (direction Y1-Y1' in the figure) from a standard position where the front face 21a of the housing fitting portion 21 is flush with the front face 42a of the substrate fixing member 40 to a position where the front face 21a abuts against the front regulating portion 44 of the substrate fixing member 40, by gaps C3 provided between the front face 21a of the housing fitting portion 21 of the housing 20 and the front regulating portions 44 of the pair of substrate fixing members 40, respectively.
For example, when the connection object S is pulled out in the forward direction from the insertion port 22 of the housing 20, the housing 20 floats in the forward direction (Y1' direction) by the elastic deformation of the elastic portion 32 of the floating terminal 30 by the gap C3 and abuts against the front regulating portion 44. Thereby, the movement in the forward direction is restricted, the connection object S can be easily pulled out from the housing space 23 of the housing fitting part 21, and deformation and damage to the housing 20 and the floating terminal 30 due to excessive pulling can be prevented. Further, when the connection object S is pulled out, the housing 20 floats rearward (Y1 direction) and returns to the standard position.
With respect to the rear side, as shown in fig. 7, the housing 20 is allowed to float in the front-rear direction (direction Y2-Y2' in the drawing) from a standard position where the front face 21a of the housing fitting portion 21 is flush with the front face 42a of the substrate fixing member 40 to a position where the rear face of the housing 20 abuts against the rear regulating portion 55 of the floating terminal fixing member 50, by a clearance C4 provided between the root portion 31a of the contact portion 31 of the floating terminal 30 and the rear regulating portion 55 of the floating terminal fixing member 50.
For example, when the connection object S is fitted into the fitting opening 22 of the housing 20, the housing 20 floats in the backward direction (Y2' direction) by the elastic deformation of the elastic portion 32 of the floating terminal 30 with the gap C4 and abuts against the backward restriction portion 55. Thereby, when the connection object S is inserted with a force larger than necessary, the force is absorbed, so that the housing 20 and the terminal 30 can be prevented from being deformed and damaged. Further, when the connection object S is embedded, the housing 20 floats forward (Y2 direction) and returns to the standard position.
The term flush used in the description of the operation of the floating connector 10 of the first embodiment above refers to a level of flush within a tolerance range.
Second embodiment
A floating connector 110 according to a second embodiment is described below with reference to fig. 8-11. As shown in fig. 8, the floating type connector 110 according to the second embodiment is provided with: a housing 120 having a front flip actuator 124 a; a floating terminal 130 disposed inside the case 120; a pair of substrate fixing members 140 provided on both left and right sides of the exterior of the housing 120; and a floating terminal fixing member 150 fixed to the floating terminal 130 and the substrate fixing member at the rear of the housing 120. A connection object S such as a board, a wire, or a board connector is embedded from the front side of the housing 120 in parallel with the board Bd (the direction of the white frame arrow in the figure).
The housing 120 is provided with a housing fitting portion 121 inside, and the housing fitting portion 121 forms a fitting opening 122 into which the connection object S is fitted and a housing space 123 located behind the fitting opening 122 to house the connection object S. The housing fitting parts 121 each have a tapered part 121b at the lower left and right, the tapered parts 121b are narrowed from the front face 121a toward the housing space 123 to facilitate introduction of the connection object S into the fitting opening 122, and the front face 121a and the tapered parts 121b are each formed at the fitting opening 122. The lower tapered portion 121b continues to the seating portion 121c where the floating terminal 130 is provided.
As described above, unlike the housing 20 according to the first embodiment, the housing 120 is a front-flip housing having the actuator 124 a. The actuator 124a is rotated on the base 124c of the housing 120 by the support portion 124b, and when the embedding of the connection object S is completed, the actuator 124a is closed (see fig. 9). Upper end 125a and lower end 125b that operate integrally with housing 120 are provided on both left and right sides of housing 120. The notch 125c is provided in front of the lower end 125b in the front-rear direction, and an upper regulating portion 143 of the substrate fixing member 140, which will be described later, is provided so as to laterally straddle the notch 125 c.
As shown in fig. 11A, the floating terminal 130 is composed of a plate-like member, and has: a contact portion 131 that contacts the connection object S; a base end portion 133 fixed to the floating terminal fixing member 150; and an elastic portion 132 located between the contact portion 131 and the base end portion 133. The contact portion 131 is divided into three, and the lower two strands are provided as terminals at the seat portion 121c of the lower side of the housing 120 and abut against the lower surface of the connection object S. The upper strand functions as the aforementioned support portion 124b, and supports the actuator 124a so as to be able to rotate. The elastic portion 132 is formed in a C-shaped curved shape in a side view of the plate-like member and is thus configured to be easily elastically deformed in the left-right direction (floating mechanism). The base end portion 133 is fixed to the floating terminal fixing member 150.
The pair of substrate fixing members 140 are integrally molded by a high-strength member such as SUS (stainless steel) material, and each have: a substrate contact portion 141 fixed to the substrate Bd at the bottom surface; and a pair of side restricting portions 1421, 1422 for restricting lateral movement of the housing 120. The bottom surface of the substrate contact portion 141 is fixed to the substrate Bd by soldering or the like. At this time, as shown in fig. 8, when viewed from the left and right sides of the floating connector 110, the positions of the side restrictions 1421 and 1422 at least partially overlap the position of the fitting opening 122. Further, when viewed from the left and right sides of the floating connector 110, at least a part of the board contact portion 141 is disposed below a position where the fitting opening 122 overlaps the side restriction portions 1421 and 1422.
The pair of substrate fixing members 140 each have an upper regulating portion 143, and the upper regulating portion 143 is bridged on the upper side of the side regulating portions 1421 and 1422 and extends so as to cross the notch 125c of the lower end 125 b. The upper restricting part 143 restricts upward movement of the housing 120. The upper end 125a and the lower end 125b of the housing 120 can float to a position where the rear end of the notch 125c abuts against the rear end of the upper restricting portion 143, and the rear end of the notch 125c constitutes a front restricting portion 144 that restricts forward movement of the housing 120.
Further, the pair of substrate fixing members 140 may be provided to have a connecting portion 145 extending on the rear side of the side regulating portion 1421. The connection portion 145 is fitted into a through hole 152a formed in the side end portion 152 of the floating terminal fixing member 150, and thereby the substrate fixing member 140 is fixed to the floating terminal fixing member 150.
The floating terminal fixing member 150 is located behind the housing 120, and is provided with: a base 151 corresponding to the mounting width of the pair of substrate fixing members 140; and a pair of side ends 152 positioned at both ends of the base 151. Groove portions 153 that hold the base end portions 133 (see fig. 11A) of the floating terminals 130 and partition portions 154 that sandwich the adjacent groove portions 153 are provided in the middle of the base 151. As described above, the connection portion 145 of the substrate fixing member 140 is fixed to the side end portion 152.
The operation of the floating connector 110 will be described based on the above-described structures of the respective members with reference to fig. 10, 11A, and 11B. The floating connector 110 is capable of floating in each of the left-right direction, the up-down direction, and the front-back direction, and has a restriction portion for each of these directions. The floating and limiting are the same as those of the first embodiment, and thus the explanation is omitted here.
First, as shown in fig. 10, in the left-right direction, the case 120 can float in the left-right direction (X-X' direction in the drawing) between the side regulating portions 1421, 1422 of the pair of substrate fixing members 140 by utilizing the gaps C11 provided between the side regulating portions 1421, 1422 of the pair of substrate fixing members 140 and the left and right side surfaces of the case 120.
Next, in the vertical direction, as shown in fig. 11B, the case 120 is allowed to float in the vertical direction (in the Z-Z' direction in the drawing) between the board Bd and the upper restricting portions 143 of the pair of board fixing members 140 by utilizing the gaps C12 provided between the upper restricting portions 143 of the pair of board fixing members 140 and the upper surfaces of the notches 125C of the lower end portions 125B of the case 120.
Next, the housing 120 is structurally divided into a front side and a rear side with respect to the front-rear direction. On the front side, as shown in fig. 11B, the housing 120 is allowed to float in the front-rear direction (direction Y1' -Y1 in the drawing) from a standard position where the front face 121a of the housing fitting portion 121 is flush with the front face 142a of the substrate fixing member 140 to a position where the front restricting portion 144 abuts against the upper restricting portion 143, by a gap C13 provided between the front restricting portion 144 located behind the notch 125C of the lower end 125B of the housing 120 and the upper restricting portion 143 of the pair of substrate fixing members 140.
Next, with respect to the rear side, as shown in fig. 11B, the housing 120 is allowed to float in the front-rear direction (direction Y2' -Y2 in the drawing) from a standard position where the front face 121a of the housing fitting portion 121 is flush with the front face 142a of the substrate fixing member 140 to a position where the rear face 121d abuts against the rear restriction portion 155, by a gap C14 provided between the rear face 121d of the housing 120 and the rear restriction portion 155 of the floating terminal fixing member 150. The term flush, as used in the above description of the operation of the floating connector 110 of the second embodiment, refers to a level of flush within a tolerance range.
As described above, in the first and second embodiments, since the substrate fixing members 40 and 140 are integrally molded from a high-strength member such as a stainless material and positioned so that the positions of the side regulating portions 42, 1421, and 1422 overlap at least part of the positions of the fitting openings 22 and 122 when viewed from the left and right sides of the connection object S and the housings 20 and 120 are able to float, it is possible to provide the floating connectors 10 and 110 capable of regulating positional deviation without applying an excessive load to the floating terminals 30 and 130 and the fitting openings 22 and 122 of the housings 20 and 120 at the time of fitting of the connection object S and at the time of assembly after the fitting of the connection object S is completed.
The preferred embodiments of the present invention have been described in detail, but the present invention is not limited to the above embodiments, and various changes and modifications can be made within the scope of the gist of the present invention described in the claims.
