Description

  The present invention relates to a connection structure between a conductor plate for electric wiring and a terminal fitting, and a connector provided with the connection structure.

  When performing electrical wiring for electrical and electronic equipment or devices, it is common to use a wire in which a bundle of many metal wires is resin-coated as electrical wiring. However, in applications where a large current flows, the resistance of the wiring itself is used. The increase in power loss was a problem. Therefore, as a means to reduce the resistance of the wiring itself, use a rectangular wire with a substantially rectangular cross section or a conductive plate punched out of a metal plate such as copper as electrical wiring to increase the space factor of the conductor part in the wiring cross section. Depending on the case, a method of reducing the resistance of the wiring may be used.

  Conventionally, as a structure for connecting a terminal fitting such as a relay connector to a conductor for electric wiring having a substantially rectangular cross section, for example, as disclosed in Patent Document 1, a conductor portion of a flat cable and a terminal fitting are connected. The structure is for the purpose, and the conductor portion of the flat cable is sandwiched between the base portion provided on the terminal fitting and the conductive portion extending in a folded shape from the side edge of the base portion, and is fixed to be conductive by welding. was there. In this connection structure, the heat generated in the welded portion is dispersed by the base portion and the like, and the contact portion fitted to the mating terminal metal fitting is less likely to become a high temperature state, thereby suppressing deterioration of the surface of the contact portion. This ensures good electrical continuity with the terminal fitting.

  Patent Document 2 discloses a ground terminal fitting that is formed of a metal plate material punched into a predetermined shape and includes a substantially flat connecting portion provided between a substantially flat terminal body and a wire crimping portion. The connecting portion is provided with a pair of first reinforcing plates extending from both side edges, and the connecting portion is overlapped with a second reinforcing plate obtained by bending a part of the terminal body, and further the first reinforcing plate. Is disclosed in which a second reinforcing plate is sandwiched between the connecting portion and the first reinforcing plate, and the second reinforcing plate is fixed so as not to be separated from the connecting portion.

  Conventionally, as shown in FIG. 6, the conductor plate and the terminal fitting are connected by connecting the conductor plate 10 for electrical wiring and the male terminal fitting 12 by caulking. This connection structure is a structure in which the terminal fitting side connection portion 16 of the male side terminal fitting 12 is caulked so as to enclose the conductor plate side connection portion 26 of the conductor plate 10. The cross section orthogonal to the longitudinal direction of the conductor plate side connection portion 26 is substantially rectangular, and the front and back surfaces of the metal plate are formed on a substantially flat surface with which the male terminal fitting 12 abuts.

  The male terminal fitting 12 is formed, for example, by bending one formed piece punched out of a thin metal plate, and inserted at the front end side thereof into a mating female terminal fitting (not shown). A portion 18 is provided. The cylindrical portion of the insertion portion 18 is provided with a locking piece 18a formed by cutting and raising a part of the wall surface obliquely rearward.

In the caulking process of this connection structure, as shown in FIG. 7, the two tips 16 c of the pair of caulking pieces 16 c bite into the surface of the conductor plate side connecting portion 26 and are caulked. At this time, each tip 16c of the pair of caulking pieces 16c is bitten at an angle spreading left and right by plastically deforming the surface of the conductor plate side connecting portion 26 while sliding on the surface of the conductor plate side connecting portion 26. Therefore, in the state after the caulking process, as shown in FIG. 7C, the caulking piece 16 c remains at a shallow position on the surface of the conductor side connection portion 14.

  The connection structure between the terminal fitting and the flat cable in Patent Document 1 is premised on welding. Therefore, it is necessary to prevent heat generation so that the heat generation is not transmitted to the contact portion that mates with the mating terminal fitting, and the terminal fitting and the conductive portion sufficiently heat the welded portion in order to obtain a good joined state. There must be. For this reason, a connection structure that satisfactorily satisfies the mutually conflicting welding conditions cannot be easily obtained. Moreover, the management of the surface state (dirt, oxidation, etc.) of each connection part of the terminal fitting and the flat cable, the maintenance of the welding apparatus and the welding electrode, etc. are very complicated and troublesome.

  Moreover, the structure which fixes the 2nd reinforcement board to the connection part upper surface by caulking the 1st reinforcement board which the earth terminal metal fitting of patent document 2 has has a certain amount of strength to the 2nd reinforcement board and the connection part. However, it is not considered that the contact portion between the second reinforcing plate and the connecting portion is electrically connected with low resistance. Therefore, the connection structure is insufficient for applications in which electrical connection with a low resistance must be made between a conductor having a substantially rectangular cross section through which a large current flows as described above and a terminal fitting such as a relay connector.

  Further, in the conventional caulking process of the connection structure between the conductor plate and the terminal fitting, as shown in FIG. 7 (c), the caulking piece 16c remains in a shallow place on the surface of the conductor side connecting portion 14, and thus sufficient. The contact state cannot be obtained, the contact resistance is high, and it cannot be applied to the connection structure of a device that allows a large current to flow.

  Further, even when the electric wiring is branched using a conductor having a substantially rectangular cross section through which a large current flows, for the same reason as described above, a branching connector having a connection structure suitable for it cannot be realized.

  The present invention was made in view of the above-described background art, and can be assembled by a simple operation, and a connection structure between a conductor plate and a terminal fitting that can realize a good mechanical and electrical connection state, And a connector having the connection structure.

A pair of caulking pieces covering the conductive plate side connection portion, and a concave portion is formed on one surface of the conductor plate side connection portion so that the tip end portions of the pair of caulking pieces can contact the inner surface. When connecting the part and the terminal fitting side connection part, the pair of Tip of the fit piece is a connection structure of the conductor plate and the terminal fitting formed by locked caulked in the recess. For example, the recess has a V-shaped cross section.

  Further, the present invention comprises a plurality of terminal fittings constituting an electrical contact, and a conductor plate for electric wiring provided with a plurality of connection portions to which the terminal fittings are attached at the end portions. A terminal fitting side connection portion connected to the conductor plate is provided, and the conductor plate is provided with a conductor plate side connection portion to which the terminal fitting side connection portion is fixed, and the terminal fitting side connection portion and the conductor plate side connection are provided. The terminal fitting side connection portion is a bottom plate with which one surface of the conductor plate side connection portion abuts, and extends from the bottom plate to the left and right, and the conductor plate A pair of caulking pieces that cover both side end surfaces and the other surface of the side connection portion, and one end of the conductor plate side connection portion has an opening so that the tip ends of the pair of caulking pieces can contact the inner surface A recess is formed, the conductor plate side connecting portion and the terminal fitting side When connecting the connection part is a connector tip of the pair of crimping pieces, which are locked caulked in the recess.

  The conductor plate forms a branched electric wiring, and a male terminal fitting is attached to one of the conductor plate side connecting portions, and a female terminal fitting is attached to the other of the conductor plate side connecting portions. is there.

  According to the connection structure of the conductor plate and the terminal fitting of the present invention, the tip of the caulking piece deeply digs into the conductor side connecting portion, the connection between the conductor plate side connecting portion and the terminal fitting side connecting portion is ensured, and the contact area Therefore, the mechanical connection strength between the two connection portions is improved, and a good electrical connection state with a small contact resistance can be obtained.

  Further, in assembling the connection structure of the conductor plate and the terminal fitting of the present invention, special equipment such as a welding device is not required, and a general crimping pliers for crimping an electric wire to the terminal fitting or other crimping device is used as it is. Can be used. Moreover, since there is no possibility that the terminal metal fitting becomes a high temperature state as in the case of welding, there is no conduction inhibiting factor such as oxidation of the surface of the contact portion fitted to the counterpart terminal fitting.

  Furthermore, the connector of the present invention has a conductor plate in which a plurality of wiring side connection portions are extended, and the terminal fitting is connected to each wiring side connection portion with the above connection structure. It is strongly fixed, and electrical wiring can be connected or branched with low electrical resistance.

  Hereinafter, an embodiment of a connection structure between a conductor plate and a terminal fitting according to the present invention will be described with reference to FIGS. The present embodiment is a structure in which a conductor plate 10 for electric wiring and a male terminal fitting 12 are connected by caulking, FIG. 1 shows a state before caulking, and FIG. 2 shows caulking. The later state is shown.

  As shown in FIG. 1, the conductor plate 10 is manufactured by integrally punching a metal plate having excellent electrical conductivity such as a copper plate, and a conductor plate side connection portion 14 is extended at the end. The conductor plate side connection portion 14 has a substantially rectangular cross section perpendicular to the longitudinal direction, and the lower surface, which is one surface of the metal plate, is formed on a substantially flat surface that comes into contact with the bottom plate 16a of the male terminal fitting 12 described later. Has been. The upper surface, which is the other surface of the conductor plate side connecting portion 14, is provided with a concave portion 14a formed in the central portion along the longitudinal direction of the conductor plate side connecting portion 14 having a substantially V-shaped cross section orthogonal to the longitudinal direction. It has been.

  The male terminal fitting 12 is formed, for example, by bending one formed piece punched from a thin metal plate. The distal end side is provided with an insertion portion 18 that fits into a female terminal fitting on the other side (not shown). The insertion portion 18 has a shape in which a formed piece is rounded into a cylindrical shape and the end portion is closed in a hemispherical shape. ing. The cylindrical portion of the insertion portion 18 is provided with a plurality of locking pieces 18a formed by cutting and raising a part of the wall surface obliquely rearward. When the male-side terminal fitting 12 is inserted to a predetermined position in a terminal housing cavity of a connector housing (not shown), the locking piece 18a hits a locking portion provided in the terminal housing cavity. The male terminal fitting 12 is prevented from coming off.

  On the other hand, on the rear end side of the male terminal fitting 12, a terminal fitting side connecting portion 16 to which the conductor plate side connecting portion 14 is attached is provided. The terminal metal fitting side connection portion 16 is erected in a substantially right angle direction from the left and right sides of the bottom plate 16a along both side end surfaces of the conductor plate side connection portion 14 and is opposed to each other. And a pair of caulking pieces 16b.

  Here, the relative relationship between the conductor plate side connection portion 14 and the terminal fitting side connection portion 16 will be described. The length in the terminal insertion direction of the bottom plate 16 a of the terminal fitting side connection portion 16 includes a flat portion longer than the length in the longitudinal direction of the conductor plate side connection portion 14. Further, the length of the caulking piece 16b in the terminal insertion direction is set to be slightly shorter than the length of the concave portion 14a of the conductor plate side connection portion 14. Further, the length from the base of the caulking piece 16b to the tip is set to such a length that it can just cover the side surface and the upper surface of the conductor plate side connecting portion 14 in a state after caulking processing described later.

  Next, caulking processing of the terminal metal fitting side connection portion 16 and the conductor plate side connection portion 14 will be described. The caulking process is performed by arranging the conductor plate side connection portion 14 in the terminal fitting side connection portion 16 and wrapping the terminal fitting side connection portion 16 from the outside. For the caulking process, for example, a known crimping pliers or other caulking jig 20 shown in FIG. 3 is used.

  First, the bottom plate 16a of the terminal fitting side connection portion 16 is placed downward on the support surface 22b at the tip of the convex die 22a formed on the lower teeth 22 of the caulking jig 20. Next, the upper teeth 24 are moved so as to mesh with the lower teeth 22. As a result, the pair of caulking pieces 16b are plastically deformed by sliding the tip 16c and the outer surface thereof along the curved guide surface 24b inside the concave mold 24a. Further, the tip 16c is curved along the concave mold 24a, further curved toward the sharpened portion 24c via the deepest portion thereof, and plastically deformed while being curved toward the center of the upper surface of the conductor plate side connecting portion 14.

  When the two tips 16c of the pair of caulking pieces 16c reach the upper surface of the conductor plate side connecting portion 14, they are locked by the concave portion 14a and start to spread inward in the direction of the V-shaped apex. Then, as shown in FIGS. 2 (a) and 2 (b), the conductor plate side connecting portion 14 is plastically deformed, and the caulking process is completed when it is sufficiently deepened.

  For the conductor plate 10 and the conductor plate side connecting portion 16, a material such as copper having a high electrical conductivity and relatively soft is suitable. On the other hand, since the male terminal fitting 12 is inserted into and removed from the mating terminal fitting, it is necessary to maintain a predetermined strength as a structure, and therefore, a material such as a relatively hard special copper alloy is used. . Therefore, the caulking piece 16 made of a relatively hard material can be deeply digged into the conductor-side connecting portion 14 made of a soft material, as shown in FIG.

  As described above, according to the connection structure of the conductor plate and the terminal fitting of the present embodiment, the recess 14a is provided on the upper surface of the conductor plate side connection portion 14 of the conductor plate 10 for electrical wiring, and the conductor plate side connection portion. 14 and the terminal metal fitting side connecting portion 16 are connected by caulking, the terminal metal fitting side connecting portion 16 covers the periphery of the conductor plate side connecting portion 14, and each tip 16c of the pair of caulking pieces 16b is in the recess 14a. Since it is locked and fixed by caulking, the tip 16c of the caulking piece 16b bites into the conductor plate side connecting portion 14 and the contact area between the conductor plate side connecting portion 14 and the terminal fitting side connecting portion 16 increases. Therefore, the mechanical connection strength of both the connection parts 14 and 16 can be improved, and a good electrical connection state with a small contact resistance can be obtained.

  In addition, the connection structure between the conductor plate and the terminal fitting of the present embodiment can use a jig such as a general crimping pliers or other crimping device as it is. Further, since the terminal fitting does not reach a high temperature state as in welding, there is no conduction inhibiting factor such as oxidation of the surface of the contact portion fitted to the counterpart terminal fitting.

The distal end side is provided with an insertion receiving portion 38 that fits into a male terminal fitting on the other side (not shown). The insertion receiving portion 38 has a shape in which a formed piece is rounded into a cylindrical shape and an end thereof is opened. Yes. The cylindrical portion of the insertion receiving portion 38 is provided with a plurality of locking pieces 36a formed by cutting and raising a part of the wall surface obliquely rearward. When the female-side terminal fitting 32 is inserted to a predetermined position in a terminal housing cavity of a connector housing (not shown), the end 38b of the locking piece 38a hits a locking portion provided in the terminal storage cavity. The female terminal fitting 32 is prevented from coming off.

  Next, the relative relationship between the conductor plate side connecting portions 34a, 34b, 34c and the terminal fitting side connecting portion 16 of the terminal fitting attached to each connecting portion will be described. The terminal insertion direction length of the bottom plate 16a of the terminal fitting side connection portion 16 includes a flat portion that is longer than the length in the extending direction of the conductor plate side connection portions 34a, 34b, and 34c. The length of the caulking piece 16b in the terminal insertion direction is set to be slightly shorter than the length of the concave portion 14a of the conductor plate side connection portions 34a, 34b, 34c. The length from the base of the caulking piece 16b to the tip is set to such a length that it can just cover the side surfaces and the upper surface of the conductor plate side connection portions 34a, 34b, 34c in a state after caulking, which will be described later. Yes.

  The caulking process of each terminal metal part side connecting part 16 and the conductor plate side connecting parts 34a, 34b, 34c is the same as the caulking process of the terminal metal part side connecting part 16 and the conductor plate side connecting part 14, and the description thereof is omitted. .
