Description

[Detailed Description of the Invention] This invention relates to a beam receptacle, and more specifically, to a twin tab receptacle configured such that tab-shaped terminals can be inserted from both ends and the tab-shaped terminals can be connected to each other.

Various connecting devices are used to connect electric wires and between electric wires and circuit boards.Among them, tab-shaped terminals and receptacles that connect to these terminals can be easily formed by press molding, so they are suitable for both communication and consumer applications. Widely used in equipment.

However, this type of connection device is generally used by attaching a tab-shaped terminal to the circuit board and attaching a tab receptacle to the wire side, and when connecting between wires, a tab-shaped plug is attached to one side, and a tab-shaped plug is attached to the other side. The two electric wires are connected by attaching the receptacles.

However, if we look at Embodiments 1 and 2 as two-way receptacles for connecting two electric wires with tab-type plugs attached, or electric wires with tab-type plugs attached and tab-type terminals attached to a circuit board, all of them have tab-type terminals. Since the insertion point is asymmetrical in the thickness direction, the insertion position is misaligned, and the insertion position is directional, the workability is poor and the strength is weak, resulting in the tab-shaped plug being inserted at intervals.

This invention aims to eliminate the above-mentioned drawbacks and is characterized by a substantially flat rectangular elastic conductive metal plate extending approximately 90' from one longitudinal end to the other.
At the same time, the metal plate is bent back in an arc shape toward one side to form a first elastic curved portion, and the other end is bent approximately 90 degrees toward the other side, leaving a first flat portion on the other end side of the metal plate. Then, it is folded back in an arc shape on one side to form a second elastic curved section, and further, from this elastic curved section, the first elastic curved section is parallel to the first flat section at a distance slightly narrower than the thickness of the tab terminal. forming a second flat portion that abuts the end edge, and bending protrusions formed on the sides of each of the flat portions outward to form a pair of introduction portions that facilitate insertion of the tab terminal; The present invention provides a twin tab receptacle characterized by the following features.

An embodiment of this invention shown in the drawings will be described in detail below.

FIG. 1 is a developed view of the twin tab receptacle of this invention, and the receptacle forming body 1 for tab terminals is substantially flat and made of a rectangular elastic conductive metal plate with elastic curved portions 2a, 2b.
, a receptacle component A consisting of flat parts 3 a and 3 b, and an introduction part 5 a that bends outward the protrusions 4 a to 4 d formed on the sides of each flat part to facilitate insertion of the tab terminal. ~5d.

As shown in FIG. 2, this tab terminal receptacle forming body 1 is constructed by bending the elastic curved portion 2a located at one end of the receptacle component A by approximately 90° toward the other side along the broken line 7a (FIG. 1), and then A first elastic curved section 2a is created by folding approximately + length of the elastic curved section 2a in an arc shape to one side so as to have a diameter, and a second elastic curved section is connected to the first flat section 3a. 2
Similarly to the first elastic curved portion 2a, b is also bent approximately 90 degrees toward the other surface along the broken line 7b, and then folded back in an arc shape toward the first surface to have a diameter approximately equal to the length of the elastic curved portion 2b. A second elastic curved section 2b is formed, and a second flat section 3b connected to the second elastic curved section along a broken line 7C is connected to the first flat section 3a by the thickness of the tab plug 13 as shown by the broken line in FIG. The receptacle portion is completed by forming parallel second flat portions 3b with a gap slightly narrower than that of the second flat portion 3b.

Note that a contact portion B is formed by bringing the outer end of the flat portion 3a into contact with the thick wall surface of the curved portion 2a.

The tab terminal receptacle of this invention has the above-mentioned configuration, and its usage will be described below.

FIG. 3 shows, as an example, a case where tab plugs 13 are connected to insulated conductive wires 10a, 10b (7) and core wires 11a, 11b by pressure bonding with ferrules using this twin tab receptacle 9. Receptacle parts 8 a and 8 b from both ends of receptacle 9
be inserted simultaneously or sequentially.

This receptacle 9 and a covered electric wire 10 as shown in FIG.
To connect the tab plug 13 attached to the receptacle 9, insert the tab plug 13 between the first and second flat portions 3a and 3b of the receptacle 9, and the tab plug 13 will be connected to both sides of the tab plug 13. Due to the action of the elastic curved parts 2a, 2b and the synergistic elasticity of the contact part B, the second flat parts 3a, 3b are brought into elastic surface contact with a moderately strong force, and can be joined with small contact resistance.

That is, as shown in FIGS. 2, 3, and 5,
Introduction parts 5a, 5b of first and second flat parts 3a, 3b
is the outer edge 2a of the first and second elastic curved parts 2a, 2b
', 2b', and there is a continuous slope between them, so when inserting the tab plug 13 between the flat parts 3a and 3b, it is necessary to
As shown in FIG. 6C, the tab plug 13 begins to touch the substantially V-shaped introduction portions 5 a and 5 b in its thickness direction, and as it is inserted, the side edges of the flat portions 3 a and 3 b sequentially touch toward the center. As shown in d, the flat part 3a finally comes into full contact with the abutting part B and is tightly supported, so that insertion can be carried out smoothly.

As described above, this invention allows one end of a substantially flat rectangular elastic conductive metal plate in the longitudinal direction to face the other surface at an angle of about 90°.
At the same time, the metal plate is folded back in an arc shape toward one side to form a first elastic curved portion, and the other end is bent approximately 90° toward the other side, leaving a first flat portion on the other end side of the metal plate. After bending, the second elastic curved section is folded back in an arc shape on one side, and the first elastic curved section is parallel to the first flat section from this elastic curved section at an interval slightly narrower than the thickness of the tab terminal. a pair of introducing portions forming a second flat portion that abuts the edge of the flat portion and bending protrusions formed on the sides of each of the flat portions outward to facilitate insertion of the tab terminal; Because of the synergistic effect of the contact portion, contact resistance is small because surface contact is made over a wide range with the tab plug.
forming annular first and second elastic curved parts having centers on a line passing between the flat parts of the first and second elastic curved parts;
The directionality should also be taken into consideration for tab terminals whose ends are bent into a crank shape by configuring the flat part edge to be set back from the edges of the first and second elastic curved parts. It has the effect of allowing easy and smooth insertion.
