Description
Technical Field
The present invention relates to a floating connector having a fixed base fixed to a substrate and a movable base fitted to a mating connector, and configured to be movable relative to the fixed base, wherein when the floating connector is fitted to the mating connector, even if there is a positional deviation between the substrates to which the connectors are attached, the positional deviation can be absorbed, and the connectors can be reliably fitted to each other.
Background
A connector called a floating type includes, for example, a fixed base fixed to a substrate and a movable base having a fitting portion to be fitted to a mating connector, and a connection member passes through the fixed base and the movable base. Since the movable base is movable relative to the fixed base by the elastic force of the connection member, even if there is a positional deviation between the board on which the floating connector is mounted and the board on which the mating connector is mounted when the floating connector is fitted to the mating connector, the positional deviation can be absorbed by the movement of the movable base, and the floating connector can be easily fitted to the mating connector (see, for example, patent document 1).

Disclosure of Invention
In the floating connector disclosed in patent document 1, for example, when a large external force is applied to the movable base in the fitting direction with the mating connector, the movable base may move so that the connection member is out of the range of elastic deformation. Thus, the coupling member is plastically deformed, and the position of the movable base relative to the fixed base in a state where the mating connector is not fitted is changed.
The present invention has been made in view of the above problems, and an object thereof is to provide a floating connector capable of preventing plastic deformation of a connection member by restricting excessive movement of a movable base.
In order to achieve the above object, a floating connector (for example, a receptacle connector 1 in an embodiment) according to the present invention includes: a movable base having an electrical insulating property and having a fitting portion (for example, a housing recess 26 in the embodiment) to be fitted to a mating connector; a fixed base having an electrical insulation property and movably loading the movable base; and a plurality of connection members passing through the fixed base and the movable base. Wherein the connection members respectively include: a lead portion fixed to the fixed base at one end of the connection member and exposed to the outside of the fixed base; a contact portion which is fixed to the movable base at the other end of the connection member, is positioned at the fitting portion, and is capable of coming into contact with the connection member of the mating connector; and an intermediate portion (e.g., an inner abutting portion 33, a bent portion 34, and an outer abutting portion 35 in the embodiment) that is elastically deformable and connects the lead portion and the contact portion. Wherein the intermediate portion is elastically deformed in a state where the connection member passes through the fixed base and the movable base, so that the movable base moves relative to the fixed base. The floating connector further includes a movement restricting member (e.g., a movement restricting buckle 40 in the embodiment) attached to the fixed base, and restricting the movable base from moving beyond a certain movement amount with respect to the fixed base. Wherein the movement restricting member includes: a press-fitting portion that is press-fitted and engaged in a slit-shaped press-fitting space (e.g., a press-fitting groove 18a in the embodiment) formed in the fixed base; and a movement restricting portion that is connected to the press-fitting portion, and that faces the movable base in a fitting direction of the mating connector and the movable base in a state where the press-fitting portion is press-fitted into the press-fitting space and is attached to the fixed base, and that restricts movement of the movable base in the fitting direction beyond the certain movement amount.
In the above floating connector, it is preferable that the movement restriction member includes a pair of leg portions connected to the press-fitting portion, provided in a pair on side surfaces of the press-fitting portion, and fixed to the board.
Preferably, the pair of leg portions are substantially parallel to the press-fitting portion, and are fitted into guide grooves formed in the fixed base so as to extend in the fitting direction, whereby the press-fitting portion is guided when being pressed into the press-fitting space.
In the above floating connector, it is preferable that a housing recess portion capable of housing the movement restricting portion is formed in a portion of the movable base that faces the movement restricting portion; the movement restricting portion is located in the housing recess and abuts against a side surface of the housing recess to restrict the movable base from moving in a plane perpendicular to the fitting direction.
In the floating connector of the present invention, the movement restricting member attached to the fixed base includes: a press-in part engaged in the slit-shaped press-in space; and a movement restricting portion that faces the movable base in a fitting direction of the counterpart connector and the movable base, and restricts movement of the movable base beyond a certain movement amount in the fitting direction. In this case, for example, by setting the distance between the movable base and the movement restricting portion to be smaller than the maximum amount of deformation of the coupling member, when the movable base abuts against the movement restricting portion, excessive movement of the movable base in the fitting direction can be restricted, and the coupling member can be prevented from being plastically deformed.
In the above floating connector, it is preferable that the movement restriction member further includes a pair of leg portions provided in pairs on the sides of the press-fitting portion and fixed to the board. In the case of such a configuration, since the movement restricting member is firmly fixed to the substrate by the leg portions in addition to the engagement with the fixed base by the press-fitting portion, even when a large external force is applied to the movable base to move, the excessive movement of the movable base can be reliably restricted against the external force.
Preferably, the pair of legs is fitted into a guide groove formed in the fixed base, thereby providing a guide function when the press-fitting portion is press-fitted into the press-fitting space. With this configuration, the press-fitting portion can be straightly pressed into the press-fitting space in the fitting direction by the guide function of the pair of leg portions, and the movement restricting member can be securely attached to the fixed base by reliably engaging the press-fitting portion with the press-fitting space.
In the above floating connector, it is preferable that a housing recess portion capable of housing the movement restricting portion is formed in a portion of the movable base facing the movement restricting portion. With this configuration, when the movement restricting portion is positioned in the housing recess and the side surface of the movement restricting portion abuts against the side surface of the housing recess, the movable base can be restricted from moving in a plane perpendicular to the fitting direction.

Detailed Description
Embodiments of the present invention will be described below with reference to the drawings. First, the structure of the receptacle connector 1 as an example of a floating connector applied to the present invention will be described with reference to fig. 1 to 8. In the present embodiment, for convenience of explanation, the front-rear, left-right, and up-down directions are defined by the directions of arrows attached to the drawings.
As shown in fig. 1, the receptacle connector 1 includes: a fixed base 10 whose lower surface is fixed to a substrate (not shown); a movable base 20 movably mounted to the fixed base 10; a plurality of connection members 30 passing through the fixed base 10 and the movable base 20; and a pair of movement restricting buckles 40 having a function of fixing the fixed base 10 to the substrate and a function of restricting excessive movement of the movable base 20 as described later. A plug connector as a mating connector, not shown, can be fitted from above into the movable base 20 constituting the receptacle connector 1. The movement restricting buckle 40 corresponds to a movement restricting member in claims.
As shown in fig. 4 (a) and 4 (b), the fixing base 10 has a substantially rectangular shape extending in the front-rear direction, and is formed of an electrically insulating resin or the like. The fixed base 10 includes: left and right walls 11,11 extending in the front-rear direction; front and rear walls 12,12 extending in the left-right direction at front and rear ends of the left and right walls 11, higher than the left and right walls 11, 11; and a flat plate-like bottom portion 13 connecting the lower end portions of the left and right walls 11,11 and the front and rear walls 12, 12. The fixed base 10 is substantially box-shaped as a whole. The fixed base 10 has a movable base housing space 14 which is surrounded by left and right walls 11, front and rear walls 12, and a bottom 13 and is open at the top.
A plurality of connecting member holding grooves 11a (see fig. 5 a) formed to extend in the vertical direction and to accommodate the connecting members 30 are provided in parallel in the front and rear of the left and right outer surfaces of the left and right walls 11, 11. A flat-plate-shaped buckle holding portion 18 and a pair of connecting portions 19,19 connecting the front and rear walls 12 and the buckle holding portion 18 are formed on the front and rear outer surfaces of the front and rear walls 12, 12. In the gap in the front-rear direction formed by the front-rear wall 12 and the buckle holding portion 18, a region formed between the pair of coupling portions 19,19 is a press-fitting groove 18a, and regions formed on the left and right outer sides of the coupling portion 19 are guide grooves 18b, which are formed to extend in the up-down direction, respectively (see fig. 5 (b)).
On the lower surface of the bottom portion 13, a positioning protrusion 15 for positioning with respect to the substrate is formed to protrude downward. In addition to the structure in which the bottom portion 13 is provided, the fixed base 10 may be a structure in which the movable base housing space 14 penetrates up and down, without providing the bottom portion 13.
As shown in fig. 6 (a) and 6 (b), the movable base 20 has a substantially rectangular shape extending in the front-rear direction, and is formed of an electrically insulating resin or the like. The movable base 20 includes: a base 21 having a rectangular frame shape; a central protrusion 22 having a rectangular lower surface and protruding downward from an inner edge of the base 21 and extending in the front-rear direction; and outer side restricting walls 25 projecting downward from the left and right end portions of the base 21 and extending in the front-rear direction. On the upper surface of the front and rear end portions of the base portion 21, stepped portions 21a extending in the left-right direction are formed.
The center protrusion 22 has: an inner side restricting wall 22a projecting downward from an inner frame edge portion of the base 21 and extending in the front-rear and left-right directions; and a flat central bottom portion 23 connected to a lower end portion of the inner limiting wall 22 a. On the upper surface side of the center protrusion 22, a housing recess 26 extending in the front-rear direction and opening upward is formed by being surrounded by the left and right inner surfaces of the inner limiting wall 22a and the upper surface of the center bottom 23. A plate-shaped fitting projection 24 is formed on the upper surface of the center bottom portion 23 so as to project upward and extend in the front-rear direction, and the fitting projection 24 is located in the receiving recess 26.
A downwardly open connecting member accommodating space 27 surrounded by the lower surface of the base 21, the left and right outer surfaces of the inner limiting wall 22a, and the left and right inner surfaces of the outer limiting wall 25 is formed on each of the left and right outer sides of the central protruding portion 22 (see fig. 7 a). As shown in fig. 7 (b), a plurality of connecting member receiving grooves 24a penetrating vertically are formed in parallel in the front and rear on the left and right side surfaces of the fitting projection 24.
The connecting member 30 is formed by punching an elastically deformable conductive metal plate into a metal needle shape, and then bending the metal needle into a predetermined shape as shown in fig. 8 (a) to 8 (c), for example. The connecting member 30 includes: a contact portion 31 extending in the up-down direction; an inner base portion 32 that bends the lower end portion of the contact portion 31 in the left-right direction at substantially right angles; an inner abutting portion 33 that bends an end of the inner base portion 32 obliquely upward; a bending part 34 for bending the upper end part of the inner abutting part 33 into an inverted U shape and elastically deforming; an outer abutting portion 35 connected to the bent portion 34 and extending downward; an outer base 36 that bends the lower end of the outer contact portion 35 in the left-right direction; a fixed-side joint portion 37 formed by bending an end portion of the outer base portion 36 downward at a substantially right angle; and a lead portion 38 formed by bending a lower end portion of the fixed-side coupling portion 37 in a right-left direction at a substantially right angle. A movable-side coupling portion 31a having a partially enlarged width in the front-rear direction is formed in the contact portion 31, and a fixed-side coupling portion 37a having a partially enlarged width in the front-rear direction is formed in the fixed-side coupling portion 37.
As shown in fig. 1, the movement restricting buckle 40 is formed into a substantially flat plate shape as a whole by punching and bending a flat plate-shaped metal plate using a press die, for example. The movement restriction buckle 40 includes: a flat plate-like connecting portion 41; a pair of right and left leg portions 42,42 extending downward from right and left end portions of the connecting portion 41; a fixing (mount) portion 43 protruding laterally outward from the lower end portion of the leg portion 42; a press-fit portion 44 extending downward from the left and right center portions of the connecting portion 41; and a movement restricting portion 45 that is bent at a substantially right angle inward in the front-rear direction at the upper end portion of the connecting portion 41 and has a substantially rectangular shape in plan view. A plurality of coupling protrusions 44a protruding in the left-right direction are formed on the left and right side surfaces of the press-fitting portion 44.
In this way, since the movement restricting buckle 40 can be formed by punching in addition to the bending of the movement restricting portion 45, it can be manufactured by an inexpensive press die with a reduced number of bending steps, and therefore, the manufacturing cost of the movement restricting buckle 40 can be significantly reduced. Since the movement restricting buckle 40 is formed on the same plane except for the movement restricting portion 45, and is formed in a substantially flat plate shape as a whole, it is easier to handle the movement restricting buckle than a movement restricting buckle in which a plurality of portions are formed so as to protrude in the front-rear direction, for example.
The structure of the receptacle connector 1 is explained above. Next, an assembly structure of the receptacle connector 1 will be explained.
First, the link member 30 is attached to the movable base 20. At this time, the contact portion 31 of the link 30 is inserted into the link receiving groove 24a of the movable base 20 from below, and the movable-side coupling portion 31a is engaged with the link receiving groove 24a, whereby the link 30 is mounted on the movable base 20. Thereby, the contact portions 31 are exposed to the left and right side surfaces of the fitting projection 24 of the movable base 20, and the inner contact portion 33, the bent portion 34, and the outer contact portion 35 of the connection member 30 are housed in the connection member housing space 27 (see fig. 3).
Next, the movable base 20 to which the connection member 30 is attached to the fixed base 10. At this time, the fixed-side coupling portion 37 of the coupling member 30 is inserted into the coupling member holding groove 11a of the fixed base 10 from above, and the movable base 20 is attached to the fixed base 10 via the coupling member 30 by engaging the fixed-side coupling portion 37a with the coupling member holding groove 11a (see fig. 3). As a result, the inner contact portion 33, the bent portion 34, and the outer contact portion 35 are elastically deformed in the connecting member housing space 27, and the movable base 20 is movable in the front-rear, left-right, and up-down directions with respect to the fixed base 10.
Next, the movement restricting buckle 40 is attached to the fixed base 10. At this time, the pair of leg portions 42 are respectively fitted into the guide grooves 18b and inserted into the guide grooves 18b in the vertical direction, so that the press-fitting portions 44 extending parallel to the leg portions 42 are press-fitted into the press-fitting grooves 18a in the vertical direction. Here, since the pair of leg portions 42 function as guides when the press-fitting portion 44 is press-fitted into the press-fitting groove 18a, the press-fitting portion 44 can be inserted straight in the vertical direction along the press-fitting groove 18a while ensuring the positional accuracy of the press-fitting portion 44 with respect to the press-fitting groove 18 a.
Thus, the coupling projection 44a formed on the press-fitting portion 44 is engaged with the press-fitting groove 18a, the movement restricting buckle 40 is firmly fixed to the fixed base 10, and the step portion 21a of the movable base 20 and the movement restricting portion 45 of the movement restricting buckle 40 are vertically opposed to each other with a constant interval. In this way, the flat plate-shaped portion of the movement restricting buckle 40 is inserted and attached to the slit-shaped press-fitting groove 18a and the guide groove 18b, and therefore, the receptacle connector 1 has a structure having the movement restricting buckle 40 and is downsized in the front-rear direction.
Next, the positioning projections 15 formed on the fixing base 10 are inserted into positioning holes (not shown) formed in the substrate, whereby the receptacle connector 1 is positioned and mounted on the substrate. The fixing portion 43 of the movement restricting clip 40 and a fixing pattern (not shown) on the substrate, and the lead portion 38 of the connecting member 30 and a wiring pattern (not shown) on the substrate are soldered and bonded to each other by heating in a reflow furnace, for example. In this way, in addition to the coupling between the lead portions 38 of the connection members 30 and the wiring pattern on the substrate, the receptacle connector 1 (the fixed base 10) is further firmly fixed to the substrate by the coupling between the fixing portions 43 of the movement restricting buckle 40 and the fixing pattern of the substrate.
The receptacle connector 1 fixed to the board is elastically deformed by the partial connection member 30 as described above, and the movable base 20 is movable in the front-rear, left-right, and up-down directions with respect to the fixed base 10. Therefore, for example, even when the mating connector is fitted in the receiving recess 26 in a state where there is a positional deviation between the substrate to which the receptacle connector 1 is fixed and the substrate to which the mating connector is fixed, the movable base 20 can move in a direction to absorb the positional deviation, and therefore, the receptacle connector 1 can be reliably fitted to the mating connector. This allows the contact portion 31 of the connection member 30 to be brought into elastic contact with the connection member of the mating connector, thereby stably maintaining the electrical connection state.
The assembling structure of the receptacle connector 1 is explained above. Next, a structure of the receptacle connector 1 that allows movement of the movable base 20 within a certain movement amount with respect to the fixed base 10 and restricts movement beyond the certain movement amount will be described. The above-mentioned certain amount of movement is the maximum amount of deformation of the connecting member 30 that can be elastically deformed, and is the same as the meaning of the claims.
For example, when the mating connector fitted to the movable base 20 is pulled out from the movable base 20, the mating connector may be operated in the left-right direction so as to be tilted. At this time, in fig. 3, the inner contact portion 33, the bent portion 34, and the outer contact portion 35 are elastically deformed so as to approach the inner limiting wall 22a or the outer limiting wall 25 from the connecting portion between the outer contact portion 35 and the outer base portion 36. When elastically deformed so as to approach the inner limiting wall 22a, the inner abutment portion 33 abuts against the inner limiting wall 22 a; on the other hand, when the movable base 20 is elastically deformed so as to approach the outer limiting wall 25, the outer contact portion 35 comes into contact with the outer limiting wall 25, whereby excessive movement of the movable base 20, such as to cause plastic deformation of the connection member 30, can be limited.
In addition to the above-described operation in the left-right direction, when the mating connector is operated in the up-down direction (fitting direction), the movable base 20 is sometimes pulled upward together with the mating connector. At this time, in fig. 2, the movement restricting portion 45 of the movement restricting buckle 40 abuts on the step portion 21a of the movable base 20, so that the upward movement of the movable base 20 can be restricted, and the excessive movement of the movable base 20 to the extent that the coupling member 30 is plastically deformed can be restricted. In the movement restricting buckle 40, the coupling projection 44a is engaged with the press-fitting groove 18a, and the fixing portion 43 is fixed by being welded to the fixing pattern on the substrate, so that even when the movable base is pulled upward with a large force and a large external force is applied to the movement restricting portion 45, the movement restricting buckle 40 does not fall off from the fixed base 10, and excessive movement of the movable base 20 can be reliably restricted.
In the receptacle connector 1 of the present invention, since the excessive movement of the movable base 20 is restricted by the movement restricting buckle 40 for firmly fixing the fixed base 10 to the board, the number of components can be reduced and the manufacturing cost can be reduced as compared with a structure in which, for example, a new component is separately provided for restricting the excessive movement of the movable base 20. Since it is not necessary to provide the new component, the receptacle connector 1 can be downsized.
In the above embodiment, the description has been given of the example in which the step portion 21a of the movable base 20 and the movement restricting portion 45 of the movement restricting buckle 40 are vertically opposed to each other, and the movement of the movable base 20 beyond a certain amount of movement in the vertical direction is restricted by the movement restricting portion 45, but the present invention is not limited to this configuration. For example, as shown in fig. 9, a substantially rectangular housing recess 121 in plan view, which can house the movement restricting portion 45, may be formed on the upper surface of the movable base 120, and the movement restricting portion 45 may be housed in the housing recess 121 with a predetermined interval in the vertical direction.
According to the configuration shown in fig. 9, the excessive upward movement of the movable base 120 is restricted by the vertical contact of the lower surface of the movement restricting portion 45 with the upper surface 122 in the housing recess 121, the excessive forward and backward movement of the movable base 120 is restricted by the vertical contact of the front and rear side surfaces of the movement restricting portion 45 with the front and rear side surfaces 123 of the housing recess 121, and the excessive leftward and rightward movement of the movable base 120 is restricted by the vertical contact of the left and right side surfaces of the movement restricting portion 45 with the left and right side surfaces 124 of the housing recess 121.
The receptacle connector 1 described in the above embodiment is an example applied to the present invention, and can be modified as appropriate within a range not departing from the gist of the present invention. For example, in the case of the movement restricting buckle 40 having a simple structure aimed at restricting excessive movement of the movable base 20, the leg portion 42 and the fixing portion 43 may be omitted, and the movement restricting buckle may be formed of the connecting portion 41, the press-fitting portion 44, and the movement restricting portion 45. With such a configuration, the press-in portion 44 is press-fitted into the press-in groove 18a and held, and the movement restricting buckle is attached to the fixed base 10 such that the movement restricting portion 45 faces the upper surface of the movable base 20. When the movable base 20 is excessively moved upward and comes into contact with the movement restricting portion 45, the upward movement of the movable base 20 is restricted by the holding force of the holding press-fitting portion 44 in the press-fitting groove 18a, and the connecting member 30 can be prevented from being plastically deformed. Since the connecting portion between the leg portion 42 and the fixing portion 43 is formed in an arc shape or a chamfered shape, the connecting portion is not obstructed by the connecting portion 19 when the leg portion 42 is inserted into the guide groove 18b in the vertical direction, and thus the leg portion can be smoothly inserted into the guide groove 18 b.

the outer limiting walls of one of the right and left rows of the connecting members abut against the outer abutting portions, and the inner limiting walls of the other row abut against the inner abutting portions, thereby limiting the movement of the movable base relative to the fixed base in a plane perpendicular to the fitting direction by a predetermined amount of movement in the right and left direction.
2. The floating connector according to claim 1, wherein the movement restriction member further includes a pair of leg portions connected to the press-fitting portion, provided in a pair on side surfaces of the press-fitting portion, and fixed to the substrate.
3. The floating connector according to claim 2, wherein the pair of leg portions are substantially parallel to the press-fitting portion, and are fitted into guide grooves formed in the fixing base so as to extend in the fitting direction, thereby guiding the press-fitting portion when the press-fitting portion is pressed into the press-fitting space.
4. The floating connector according to any one of claims 1 to 3, wherein a housing recess portion that can house the movement restricting portion is formed at a portion of the movable base that opposes the movement restricting portion;
the movement restricting portion is located in the housing recess and abuts against a side surface of the housing recess to restrict the movable base from moving in a plane perpendicular to the fitting direction.
