Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solderless wire connector, and particularly to a solderless wire connector.
In terms of construction, it relates to a tap connector for making a T-connection or an X-connection to a continuous wire.

- In a particular aspect, the invention provides a resilient slotted contact element in a plastic insulating body which is temporarily deployed for introducing an electrical wire, and a connection to the electrical wire is made by forced insertion of said contact element. This invention relates to the improvement of solder-free electric wire connectors.

Solderless wireless connectors having slotted contact elements in hinged insulating bodies are disclosed, for example, in U.S. Pat. Disclosed.

In these wire connectors, a contact element comprising a slotted metal plate is pressed into contact with the wire so that the contact leaves are elastically deployed.

If the outer leaflet of the contact element is thus deployed towards or into the hinge area, as in the wire connector disclosed in U.S. Pat. No. 3,388,370, the stress caused by this is ultimately reducing the effect.

Increasing the thickness of the insulating body in the hinge area effectively prevents self-recovering electrical breakdown, but the two halves of said body are easily spaced a sufficient distance to allow lateral insertion of electrical wires. The hinge areas are hardened to such an extent that they cannot be separated from each other.

It has therefore been found necessary in such connectors to widen the longitudinal slot to a width equal to at least a major portion of the diameter of the wire receiving passage.

However, while the extra slot width allows insertion of the wire without excessive bending in the thickened hinge area, it allows for loose movement of the wire within the passageway, ultimately resulting in poor electrical connection. deteriorate.

According to the invention, wire insertion is achieved by arranging the hinge along a line between the plane of the contact element insertion surface and the nearest parallel plane thereto that is tangential to the adjacent wire receiving passage. Allowing wide-area deployment of the hinged body so as to reduce the width of the slot to a minimum and ensure improved confinement and substantial immobility of the connected wires, yet still have a hinged area during the forced insertion of the contact element. It has been discovered that pores prevent excessive weakening or stress from occurring.

Next, the present invention will be described in detail with reference to the accompanying drawings.

The connector 10 of the present invention, shown in FIG. 1, comprises a monolithic body 11 of molded plastic insulating material and a slotted contact element 12 of double bent metal. .

Although single planar elements such as those disclosed in U.S. Pat. Make it even easier.

The body 11 is passaged to define passages 13, 14 for receiving and supporting wires, and the flat top surface of the body 11, as best shown in FIG. slot 1 for slidably receiving a contact element 12 inserted through an opening 17 defined in 18;
Slots are formed transversely to the passages 13, 14 to provide for passages 13, 16.

The cover 23 is coupled to the main body along a hinge 31.

The body 11 is slotted along one edge to define a narrow edge slot 19 and has a slot formed therein along a slot 27 from the passageway 14 past a portion of the passageway 13 to the opposite side. A slot is defined up to the hinge area 20 extending along the edge.

The hinge area 20 is located between the plane of the flat top surface 18 and a second plane parallel to the plane and tangent to the passageway 13 at a line closest to the top surface 18 .

The passageway 14 is open along the entire length of the body 11.

In contrast, the passageway 13 preferably has an end wall 2 at one end.
Closed by 1.

The end wall 21 effectively insulates and protects the wire end inserted longitudinally into the passageway 13.

Extension port 22 of opening 17 allows inspection of the wire end to ensure that it extends past slot 15 and contact element 12 prior to completing the connection.

The body 11 is thickened in the center along the hinge edges, thereby forming a band 30 extending over the adjacent ends of the slots 15 and 16.

The band 30 is continuous across the bottom surface of the body 11 as a series of longitudinal ridges 32, these ridges 32 being used when pushing the contact element 12 into the insulating body and driving it onto an insulated wire. or form a reinforcing surface that is supplied with force by a press.

When making a T-connection, the wire end is inserted into the passage 13,
The two parts of the body 11 are unfolded apart from each other about the hinge area 20 and a continuous electrical wire is then inserted laterally through the temporarily enlarged edge slot 19.

The contact element 12 is pushed into the interior of the body 11 and engaged with the wire, and then, after the cover 23 is folded over the surface of the body, the end portion 24 is brought into contact with the extending edge 25° 26.
The top snaps into place.

The edge slot 19 is substantially completely closed and the wire is held immovably within the passageway 13.14.

When the contact element 12 is pressed onto the wires supported in the passages 13, 14, the outer contact leaf 2 of the contact element 12
8.29 is pushed outward, and the outer contact leaf 28 is thrown by the thrower 1-
15.16 exerts a tendency to compress the plastic body 11.

Due to its unique arrangement, the hinge area 20 remains unaffected and retains its full strength as well as its thickness, thereby preventing a reduction in the insulation properties at the point of impact.

The thickness of band 30 provides continuous complete insulation on outer contact leaf 28.

The body 40 of FIG. 4 differs from the body 11 shown in FIGS. 1 and 2 in the location of a slot 44 extending from the hinge area to 44 for receiving a continuous electrical wire.

In the structure shown in FIG.
The main body 40 is formed with two slots, namely, a slot 41 is formed between two wire receiving passages 43 and 44, and a hinge area 50 is formed from the passage 43. A slot 47 is formed in addition to the edge slot 47 extending up to .

This structure also allows the hinge area 50 to be located between two parallel planes as described in connection with FIG.

FIG. 4 also illustrates a modification in which the end wall 21 shown in FIG. 1 is omitted, thus allowing interconnection of two continuous wires by an X-connection.

Although the invention has been described above in connection with a connector for making a connection between two wires, connectors for three or more wires may equally well be made in accordance with the principles of the invention. It will be understood that this can be done.
