With this structure, since plural contact projections abutting on the surface of the male tab terminal are formed along the terminal inserting direction, even for a short-size male tab terminal having small inserting depth one of the contact projections contacts with the short-size male tab terminal to be capable of connecting obtain the connection at all times.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal structure having a conductive contact plate which is elastically pressed against the surface of a male tab terminal to be inserted, and more particularly to a female connector having general versatility. The present invention relates to a terminal structure.

[0002]

2. Description of the Related Art As a terminal structure of a connector, as shown in FIG. 7, a box-shaped female terminal 1 and a flat male tab terminal 2 are used. By inserting the male tab terminal 2 between the cantilever and the contact plate portion 4 having a spring property and bringing the terminals into contact with each other, conduction between the electric wires connected to the terminals 1 and 2 is established. There is something to plan.

[0003] In order to suppress an increase in the electrical resistance at the electrical connection between the terminals due to aging or use in a poor environment, for example, Japanese Patent Application Laid-Open No. 59-59480 discloses "Terminals". In the "electrode portion", as shown in FIG. 8, the contact plate portion 4 of the female terminal 1 is formed on a curved surface 8 which is recessed in the width direction, and both edges 9 extending in the extending direction of the contact plate portion 4 are male. There has been proposed a projection 7 which is in contact with a tab terminal and forms a local electrical contact. Thereby, the electric connection part is provided airtight while the elastic pressing force is concentrated on the minute area,
The contact surface with the outside air was reduced, and the rise of the electric contact resistance could be suppressed.

[0004]

However, in the above-described conventional terminal structure, the male tab terminal is preferably only formed to a predetermined size regardless of the form of the contact plate portion 4 of the female terminal 1. Was. That is, the male tab terminal 2 is
As shown in (1), when the insertion into the female terminal 1 was formed to the predetermined size of (a), it was possible to reach the apex of the contact plate portion 4 and make good contact with the contact plate portion 4. Whereas
In the case of (b) formed in the short dimension, the contact did not reach the top of the contact plate portion 4 and good connection could not be achieved. If one type of female terminal can be connected to, for example, a mating male tab terminal to be mated with a connector, or can be connected to a short busbar terminal formed by a busbar on a circuit board, and may have a different shape and size. If it can be applied to the male tab terminal, it is desirable to reduce the number of parts with compatibility and to reduce the management cost. However, as described above, since the conventional structure lacks versatility, only the corresponding terminals can be applied, which causes a problem such as an increase in the number of components. The present invention has been made in view of the above circumstances, and has an object to provide a terminal structure of a female terminal that can be applied without being affected by the form of a male tab terminal, and to ensure versatility and reduce management costs. And

[0005]

According to the present invention, there is provided a terminal structure having a conductive contact plate which is elastically pressed against the surface of a male tab terminal by inserting the male tab terminal. In the structure, a plurality of contact protrusions projecting from the plate surface of the contact plate portion and contacting the male tab terminal surface are formed along the terminal insertion direction.

In this terminal structure, since a plurality of contact projections abutting on the surface of the male tab terminal are formed along the terminal insertion direction, the contact projections of the short male tab terminal having a small insertion amount are formed. One can contact and always connect.

Further, in the terminal structure according to the present invention, the plurality of contact protrusions project from a free end side of the contact plate portion formed by bending a substrate portion into a cantilever shape toward a bent base portion. It may be characterized in that it is formed so that the amount increases sequentially.

In this terminal structure, the plurality of contact protrusions are
Since the contact plate portion is formed so as to gradually increase from the free end side toward the bent base portion, the male tab terminal may be temporarily pressed against only the contact protrusion near the bent base portion to cause insufficient spring force. Even in this case, the shortage of the engaging force can be compensated by the amount of protrusion.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a terminal structure according to the present invention will be described below in detail with reference to the drawings. FIG.
1 is a partially cutaway perspective view of a terminal structure according to the present invention, and FIG.
3 is a sectional view of a terminal structure for explaining the operation. As shown in FIG.
0 denotes a female terminal 11 formed by bending a single conductive metal plate.
The male tab terminal 2 in the mating connector housing is housed in a connector housing (not shown).
(See FIG. 7).

In the female terminal 11, a wire connecting portion 12a for crimping and crimping the electric wire 60 and a conductor connecting portion 12b for crimping and crimping the conductor 62 are formed on the rear end side. An electric connection portion 14 for making electrical contact with the second member 2 is formed.

The electrical connecting portion 14 is formed by bending a pair of shoulder pieces extending from the left and right sides of the board portion 13 into a box shape, and bending the front end of the board portion 13 rearward to form a cantilever. It has a contact plate portion 15 formed in a shape and arranged inside the box. The contact plate portion 15 is formed in a high mountain shape at the center, and the front side and the rear side are inclined surfaces 17 and 19. The contact plate portion 15 is configured to sandwich the male tab terminal between the electrode surface formed in a box shape and elastically press the male tab terminal surface in the vicinity of the central portion of the mountain shape. As shown in FIG. 2, a conical first contact projection 21 is formed on the top. Also, the inclined surface 1 on the front side
7, a conical second contact protruding portion 23 is formed at a position near the top. That is, these contact protrusions 2
The protrusions 1 and 23 are provided along the terminal insertion direction, and can concentrate the elastic pressing force on the male tab terminal surface. The contact plate portion 15 has a front inclined surface 17 that applies a spring pressure to the male tab terminal and serves as an insertion guide surface for the male tab terminal.

In the terminal structure 10 configured as described above, when the tab size of the male tab terminal 2 is long, the first tab is inserted with the male tab terminal 2 inserted as shown in FIG. The contact projection 21 presses the surface of the male tab terminal to establish electrical connection. On the other hand, the tab dimension of the male tab terminal 2 is short, and as shown in FIG. 3B, the male tab terminal 2 does not reach the central portion of the chevron of the contact plate portion 15 with the male tab terminal 2 inserted into the electrical connection portion 14. If not, the second contact projection 23 presses against the male tab terminal surface to establish electrical connection. That is, in this terminal structure 10, since a plurality of contact protrusions that come into contact with the male tab terminal surface are formed along the terminal insertion direction, the contact plate portion 15 must be provided regardless of the tab size of the male tab terminal 2. An electrical connection can always be made with a contact allowance that can make contact.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, only the shape of the contact projection is different from that of the previous embodiment, and the other portions are formed in the same manner. In the terminal structure 30 of this embodiment, a first contact protrusion 31 having a wave shape perpendicular to the terminal insertion direction is formed on the top of the contact plate 15. A second contact projection 33 having a corrugated shape, which is also perpendicular to the terminal insertion direction, is formed at a position near the top of the inclined surface 17 on the front side. That is, these contact protrusions 31, 33
Are protruded along the terminal insertion direction and can concentrate elastic pressing force on the surface of the male tab terminal. The contact plate portion 15 has a front inclined surface 17 that applies a spring pressure to the male tab terminal and serves as an insertion guide surface for the male tab terminal.

In the terminal structure 30 configured as described above, the first and second contact projections 31, 33 operate in the same manner as in the previous embodiment, and can always contact the male tab terminal.
However, by being formed in such a wave shape,
Assuming that the spring pressure of the contact plate portion 15 is equivalent to that of the previous embodiment, the contact plate portion 1 that contacts the male tab terminal
The insertion force of the male tab terminal can be reduced by the amount by which the contact surface of No. 5 is increased by the wave shape.

Next, still another embodiment of the present invention will be described with reference to FIGS. In these embodiments, the contact protrusions are provided in a conical shape similar to the contact protrusion of FIG. 2 in FIG. 5 and in a wave shape similar to the contact protrusion of FIG. 4 in FIG. The only difference is that it is formed,
Since both embodiments are substantially the same, these embodiments will be described simultaneously.

In the terminal structures 40 and 50 shown in FIGS. 5 and 6, first contact projections 41 and 51 are formed on the top of the contact plate 15. Also, the inclined surface 1 on the front side of the contact plate portion 15
The second contact projections 43 and 53 are formed at the top of the 7. These contact projections 41, 51, 43,
Reference numeral 53 is formed so that the protruding amount of the contact portion 15 is gradually increased from the free end side toward the bent base portion from the free end side of the contact plate portion 15 formed by bending the substrate portion 13 from the front end to form a cantilever beam. That is, the second contact protrusions 43 and 53 are formed to have a larger protrusion amount than the first contact protrusions 41 and 51. Note that the other embodiments are formed in the same manner as the above embodiments.

In the terminal structures 40 and 50 configured as described above, when the tab size of the male tab terminal is long, the small first contact protrusions 41 and 5 and 5 are used in the same manner as described in the previous embodiment.
1 presses the male tab terminal surface to establish electrical connection.
On the other hand, when the tab dimension of the male tab terminal is short, the large second contact projections 43 and 53 press the male tab terminal surface to make electrical connection. In this case, since the second contact protrusions 43 and 53 are formed near the bent base portion of the contact plate portion 15, the distance from the male tab terminal is increased, resulting in insufficient engagement force. However, since the protrusion amount is formed large so as to compensate for the shortage of the engaging force, the first contact protrusions 41 and 51 are brought into contact with the same pressing force as when pressing the male tab terminal surface. it can.

In each of the above-described embodiments, each of the contact projections is formed on the two contact plate portions. However, the present invention is not limited to such a configuration, and two or more contact projections may be provided. Can be. Further, in each of the embodiments described above, the terminal structure is described as being fitted with the connector. However, the terminal structure of the present invention may be applied to a relay connector, a joint connector, a bus bar terminal, and the like.

[0019]

As described in detail above, the terminal structure according to the present invention can always provide a good electrical connection regardless of the tab size of the male tab terminal. As a result, the terminal structure has compatibility, and for example, an increase in the number of components can be prevented, and a reduction in management cost and the like can be realized.
