Description
Technical Field
The present invention relates to a terminal having a contact portion inserted into a housing with play, a connector using the terminal, and a connector device including the connector and a mating connector.
Background
For example, as described in many documents such as japanese patent No. 6087335 (patent document 1), a lance-shaped locking member is often used to fix the terminal to the housing. In the case of using the lance-shaped locking piece, the terminal is not fixed to the housing but is inserted with play into the housing. Therefore, when the terminal is brought into contact with the mating terminal, the terminal floats in the housing in accordance with the movement of the mating terminal, and this operation contributes to smooth contact with the mating terminal.
Patent document 1: japanese patent No. 6087335
The use of a lance lock to secure the terminal to the housing so that it floats within the housing has many advantages but problems can occur.
For example, in a connector for an automobile, a large number of terminals, for example, 100 or more terminals may be arranged in the connector. The connector is used in a state of being mounted on a substrate such as a rigid substrate or a Flexible Printed Circuit (FPC), but when the connector in which the large number of terminals are arranged is mounted on the FPC, for example, it is necessary to position and insert the connection portions of all the terminals into the holes of the predetermined SMT pads of the substrate provided corresponding to the connection portions, and then solder the connection portions.
However, as the number of terminals increases, it becomes difficult to maintain the accuracy of positioning. The positioning with low accuracy cannot be performed or soldering is insufficient, and if stress is generated after insufficient soldering, solder cracks may be generated.

Detailed Description
Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the above embodiments, but may be modified in various ways.
Fig. 1 and 2 show a perspective view of a connector device 1 according to an embodiment of the present invention. The connector device 1 is configured by a pair of a connector 2 and an object connector 6 according to an embodiment of the present invention. The connector 2 and the mating connector 6 can be freely fitted to each other and can be released from the fitting. Fig. 1 shows a state after the connector 2 and the mating connector 6 are fitted to each other, and fig. 2 shows a state before these are fitted to each other.
At the time of fitting, the front end side of the housing 11 of the connector 2 is inserted into a fitting port 63 provided in the mating housing 61 of the mating connector 6. As a result, in the connectors, the terminals 10 arranged in the housing 11 of the connector 2 are connected to the terminals 62 arranged in the mating housing 61 of the mating connector 6, respectively.
The terminals 10 of the connector 2 are soldered to the FPC7, for example, with the connection portions 31 inserted through the through holes 71 of the FPC 7. On the other hand, the mating terminals 62 of the mating connector 6 are soldered to predetermined positions on the substrate 3, for example. As a result, the substrate 3 and the FPC7 can be electrically connected by the connection between the terminals 10 and the counterpart terminals 62. The fitted state of the connector 2 and the mating connector 6 can be locked by using a lock unit 12 provided in a housing 11 of the connector 2. The connector 2 may be provided with a protrusion 13 for determining the distance from the FPC board 7 so as to more reliably solder the terminal 10 to the FPC board 7, or the attachment fitting 8 may be provided to reinforce the fixation of the connector 2 to the FPC board 7. The mounting metal fitting 8 is soldered to the FPC board 7 together with the terminals 10.
Fig. 3 and 4 are perspective views of the terminal 10, fig. 5 is a perspective view of the connector 2, in other words, a sectional perspective view of the connector 2 provided with the terminal 10, and fig. 6 is a sectional view of the connector device 1 at the time of fitting, in other words, a sectional view taken along line a-a of fig. 1.
The terminal 10 is formed by punching a single metal plate and then bending the metal plate into a substantially rectangular cross section. Since the terminal is formed of one metal plate, all the portions included in the terminal 10 are connected to each other.
The terminal 10 includes, along a contact direction "α" with a counterpart terminal: the contact portion 20, the fixing portion 30, the elastic displacement portion 40 connecting the contact portion 20 and the fixing portion 30, and the stopper member 50.
The terminal 10 can be inserted into the terminal installation space 14 of the housing 11 through the insertion port 15 provided on the rear side of the housing 11, that is, on the side opposite to the contact side of the counterpart terminal 62. The plurality of terminal installation spaces 14 are arranged in the contact direction "α" in the housing 11, and each of them has a substantially rectangular box shape. The insertion of the terminal 10 into each terminal installation space 14 is performed in order from the front side of the terminal 10, i.e., the contact side with the counterpart terminal 62, the contact portion 20, the elastic displacement portion 40, the stopper member 50, and finally the fixing portion 30. Among the above portions, the portion fixed to the terminal installation space 14 is only the fixing portion 30. Therefore, insertion into the terminal installation space 14 is smoothly performed except for the fixing portion 30. In particular, the contact portion 20 is inserted into the terminal installation space 14 with play so as to be able to float in the terminal installation space 14, in other words, so as to be able to freely move.
The contact portion 20 is a substantially cylindrical member extending along the contact direction "α". Mainly composed of a bottom plate 20a, a right plate 20b, a left plate 20c, an upper plate 20d, and a contact piece 23 continuous with the upper plate 20 d. For convenience, in this specification, the lower side, the right side, the left side, and the upper side of the terminal 10 are referred to as "bottom", "right", "left", and "upper", respectively, as viewed from the side in contact with the counterpart terminal 62. However, for the sake of convenience, any direction is defined as "bottom", "right", "left" and "upper" freely (the same applies hereinafter).
The upper panel 20d may be formed in two layers by folding a part of the right panel 20b and a part of the left panel 20c horizontally upward, for example. Strength is thereby improved by forming in two layers. On the other hand, the contact piece 23 is formed by bending only the right plate 20b by one plate, for example. By providing a plate, the contact strength with the counterpart terminal 62 is sufficiently ensured, and the force applied at the time of contact is reduced.
A substantially cylindrical terminal insertion space 22 into which the mating terminal 62 is inserted is defined inside the contact portion 20. By forming the substantially cylindrical shape, the target terminal 62 inserted inside can be more reliably captured and positioned, and therefore the target terminal 62 can be more reliably brought into contact with the contact piece 23.
The contact piece 23 is a plate-like body that communicates with the insertion hole 16 (see fig. 5) provided at the end of the housing 11 and extends inside the terminal insertion space 22. The contact piece 23 extends along a contact direction "α" with the mating terminal 62 inserted through the insertion opening 16. In this way, the effective fitting length can be increased by matching the direction "α" in which the contact 23 extends and the direction "α" in which the contact 23 contacts the target terminal 62.
A free end 23b is formed on the contact side of the contact piece 23 with the counterpart terminal 62. When the mating terminal 62 is accommodated in the terminal insertion space 22, the contact piece 23 can contact the mating terminal 62 from the free end 23b side. In order to more reliably contact the mating terminal 62, the vicinity of the center of the free end 23b is bent toward the inside of the terminal insertion space 22, and a contact portion 23a that contacts the mating terminal 62 is formed.
The contact portion 20 is connected to one end of the elastic displacement portion 40, in other words, an end portion on the side opposite to the side of the fixing portion 30 fixed to the housing 11 in the contact direction "α". The contact portion 20 inserted into the terminal insertion space 22 with play can float in the terminal insertion space 22 by the action of the elastic displacement portion 40, and therefore, for example, axial displacement of the counterpart terminal 62 accommodated in the terminal insertion space 22 can be effectively absorbed.
At least a portion of the fixing portion 30 extending along the contact direction "α" is a press-fit member. Mainly comprises bottom plates 30a, 30e, a right plate 30b and a left plate 30c on the rear side and the front side of a connecting part which is approximately コ -shaped in cross section. The right plate 30b and the left plate 30c are connected to each other via the bottom plates 30a and 30e, and the other portions are cut away. In the case where the fixing portion 30 is provided, there is no need to provide a lance-shaped locking member on the outer shell 11, and therefore a mold configuration for manufacturing the outer shell 11 can be simply provided.
The serrated locking projections 33 are provided on the upper portions of the right plate 30b and the left plate 30c so as to project upward. The vertical dimensions of the right plate 30b and the left plate 30c and the vertical dimension of the locking projection 33 are set to match the rear dimension of the terminal installation space 14. Specifically, the vertical dimensions of the right plate 30b and the left plate 30c are set as follows: is larger than the contact portion 20 and the stopper member 50, for example, the right plate 20b and the left plate 20c of the contact portion 20. In the terminal installation space 14 where the right plate 30b and the left plate 30c are installed, the groove 14a is cut upward. By making the right plate 30b and the left plate 30c follow the groove 14a, the terminal 10 is guided at the predetermined height position in the terminal installation space 14, and is press-fitted and fixed by the locking protrusion 33. The terminal installation space 14 is further provided with a groove 14b (see fig. 6) corresponding to the curved surface 21b provided on the front side of the contact portion 20 of the terminal 10 for guiding the terminal 10. The groove 14b extends in the contact direction "α" to the vicinity of the insertion opening 16 of the housing 11, and is set to a sufficient size to prevent collision with the curved surface 21 a.
The vertical radial dimension of the right plate 30b and the left plate 30c is larger than the dimensions of the contact portion 20 and the stopper member 50, and the contact portion 20 and the stopper member 50 are positioned at substantially the middle position of the right plate 30b and the left plate 30c in the vertical direction, so that the contact portion 20 and the stopper member 50 have a gap in the vertical direction with respect to the inner wall of the terminal installation space 14. As a result, the contact portion 20 can be moved in the vertical direction by the gap.
A convex portion 34 is further provided on the outer surface of each of the right plate 30b and the left plate 30c in an outward direction. The position of the fixing portion 30 in the left-right direction with respect to the terminal installation space 14 is defined by the convex portion 34. Since the lateral radial dimension of the projection 34 is larger than the dimensions of the contact portion 20 and the stopper member 50, the contact portion 20 and the stopper member 50 have a gap in the lateral direction with respect to the inner wall of the terminal installation space 14. As a result, the contact portion 20 can also be operated in the left-right direction by the gap.
As described above, the contact portion 20 and the stopper member 50 are set to have a smaller radial dimension in the vertical and horizontal directions than the fixed portion 30, and as a result, the contact portion 20 is inserted into the terminal installation space 14 with play and can float in the terminal installation space 14 by the elastic displacement portion 40.
The connecting portion 31 of the thin strip extends further rearward from the rear edge of the left plate 30c, in other words, in the end portion of the fixing portion 30 on the side opposite to the stopper member 50, along the contact direction "α". The connection portion 31 is an exposed portion 31a exposed to the outside of the housing 11 after being fixed to the housing 11. The terminal 10 can be soldered with the exposed portion 31a inserted through the through hole 71 of the FPC board 7. When the terminal 10 is installed in the housing 11, the fixing portion 30 of the terminal 10 is positioned in the terminal installation space 14 by the right and left plates 30b and 30c and the convex portion 34, and the distal end side of the connecting portion 31 is also positioned in the terminal installation space 14 by this positioning. Therefore, the arrangement of the plurality of exposed portions 31a on the distal end side of the connecting portion 31 and the arrangement of the plurality of through holes 71 of the FPC board 7 can be easily adjusted, and even when the plurality of exposed portions 31a need to be inserted into the through holes 71, the insertion work and the like are not hindered by the positional displacement thereof. The connecting portion 31 may be bent in the direction toward the inside (inside of the letter コ) of the terminal 10 in the vicinity of the center 32. By forming the extra length portion by providing the bent portion 32, the stress of the terminal 10 can be absorbed, and solder cracks can be prevented.
The elastic displacement portion 40 is a plate-shaped member extending along the contact direction "α" on the bottom surface when viewed from the contact side with the counterpart terminal 62. On the other hand, the stopper member 50 is an opposed plate-shaped member extending in the contact direction "α" on the left and right sides when viewed from the contact side with the mating terminal 62. By these elastic displacement portion 40 and stopper member 50, a substantially cylindrical member is formed in the same manner as the contact portion 20. These elastic displacement portion 40 and stopper member 50 are disposed at positions substantially overlapping each other in the contact direction "α". In other words, at least a portion thereof overlaps each other along the contact direction "α". As a result, the length of the terminal 10 in the contact direction "α" becomes shorter.
One end portion, i.e., the rear end portion of the elastic displacement portion 40 is supported via the bottom plate 30e of the fixing portion 30 in a state of being actually fixed to the housing 11. On the other hand, the other end of the elastic displacement portion 40, i.e., the front end, is not actually fixed to the housing 11, and is connected only to the bottom plate 20a of the contact portion 20. As a result, the contact portion 20 inserted into the terminal installation space 14 with play can float around the bottom plate 30e of the fixing portion 30 by the action of the elastic displacement portion 40. Preferably, the resiliently displaceable portion 40 is bent about its middle. By providing the bent portion 41, the elastic action can be enhanced. The bent portion 41 is preferably disposed inside the area space formed by the stopper member 50. With this arrangement, the terminal 10 can be prevented from being enlarged. The elastic displacement portion 40 is freely displaceable within the area space defined by the stopper member 50. With this displacement, the contact portion 20 can also float freely inside the terminal installation space 14.
The stopper 50 is mainly composed of a right plate 50b and a left plate 50 c. The stopper member 50 is provided on the front side thereof, in other words, on the side opposed to the contact portion 20 in the contact direction "α" with the counterpart terminal 62, in a state separated from the contact portion 20 in the contact direction "α". Since the stopper member 50 is separated from the contact portion 20, a gap 17 formed by, for example, a narrow slit may be provided therebetween. By providing the gap 17, the front edge 52 of the stopper member 50 and the rear edge 24 of the contact portion 20 face each other while being separated from each other. The edge portion 52 and the edge portion 24 are separated from each other in this manner, but when the contact portion 20 is operated, they are brought into a state capable of colliding with each other by the action of the elastic displacement portion 40, for example. The size of the gap 17 is adjusted to a size capable of such collision. By providing the stopper member 50, it is possible to prevent the "effective fitting length" from being shortened due to excessive floating of the terminal 10 in the housing 11. The "effective chimeric length" herein means: when the connector 2 is fitted to the mating connector 6, the mating terminal 62 has a length in contact with the contact piece 23 of the contact portion 20, particularly the contact portion 23a, in the contact direction "α" from the time when the contact is actually started to the time when the fitting is completed. In order to reliably prevent the damage of the terminal 10, the size of the gap 17 is preferably set smaller than the "effective fitting length". The stopper member 50 is not directly fixed to the terminal installation space 14, but is indirectly fixed by the fixing portion 30, and thus is fixed to the terminal installation space 14 substantially in the same manner as the fixing portion 30. Therefore, the stopper member 50 can function as a stopper when colliding with the contact portion 20.
The present invention is not limited to the above-described embodiments, and various other modifications are possible. For example, the terminal is not necessarily formed of a metal plate, and a mold may be used to form a casting.
In addition, the right plate 30b and the left plate 30c are not necessarily connected to each other at the bottom plate 30e of the fixing portion 30 that supports the elastic displacement portion 40, and the elastic displacement portion 40 may be supported by only one of the right plate 30b and the left plate 30 c.
The gap 17 is not necessarily provided between the contact portion 20 and the stopper member 50, and the contact portion 20 and the stopper member 50 may be connected to each other, and the gap may be provided between the stopper member 50 and the fixing portion 30. In this case, the rear edge of the stopper member 50 and the front edge of the fixing portion 30 face each other in a state separated from each other, and the left and right plates of the fixing portion 30 function as the stopper member.
The surface of the facing edge portion may be flat or curved. By forming the curved surface, damage at the time of collision can be suppressed.
Fig. 7 shows the terminal 10A after the stopper member 50A is deformed. In the terminal 10A, the same components as those of the terminal 10 are denoted by the same reference numerals. The stopper member 50A has an upper plate 50d in addition to the right plate 50b and the left plate 50 c. The upper plate 50d is abutted with the left and right side plates 50b and 50c in a state of being rolled in toward the inside of the terminal 10 above the respective side plates, for example, thereby forming a rolled portion 51 e. By providing the upper plate 50d and forming the roll portion 51e, the strength of the stopper member 50 can be improved. Therefore, even when the stopper member 50A collides with the contact portion 20, it is not easily deformed or damaged.
