The present invention relates to a wire connector for simultaneously connecting and cutting wires.

At the connector for terminating the wire, the end of the wire shall be pushed into the opening at one end of the connector until contact is made in the connector. The interleaving parts then move together, whereby the wires apply force into the contact element to complete the electrical connection. Waterproof grease is often sandwiched between the fittings to make the final water resistant connection. Such connectors are disclosed in US Pat. Nos. 3,573,723 and 3,656,088.

The user of such a connector has sometimes found that the end of the wire is not inserted sufficiently into the connector so that the connection is not made when the parts move together. It has also been found that sometimes plastic wire insulation stretches so much that it extends beyond the conductor, so that even if the wire end is inserted into the connector, only the wire's insulation is forced into the contact element, thus preventing wire connection.

The wire connector disclosed in US Pat. No. 3,202,957 achieves good connection of the wire by extending the opening of the wire through the connector body. The end of the wire has the difficulty of not being immediately waterproofed out of the connector prior to connection. Although waterproof grease can be provided in the connector body, there is a difficulty in the absence of wires. Although waterproof grease may be provided in the connector body, once the wire is cut and the cut end is removed from the connector body, a passage may be provided to the contact element through which water may enter the connector and short the connection. have.

The present invention provides a wire connector having an insulating body, an insulating cover, and a wire connector element. The body consists of a bottom wall, a pair of generally parallel side walls extending generally vertically from the bottom wall, and an end wall of the body and is hollow and open at the top. It is open for access to at least one wire on the end wall. The wire connector element is U-shaped and elastic with wide and thin U-shaped legs.

One of the legs is formed with at least one wiring slot extending from the top of the leg toward the bottom of the U and the second leg is aligned with the at least one wiring slot of the first leg and the upper edge thereof It is sharply carved along.

The connector element is located in the body with a sharply shaved second leg extending over and in contact with the bottom portion of U on the bottom wall of the body and over the inclined portion of the body end wall. The cover and the body are formed to be fitted together. The cover is configured to lead the wire into each connector element slot and cooperate with the sharp second leg of the connector element to cut at least one wire extending through the connector when the cover and the body are fully fitted together. The body and the cover are formed to seal the ends of the connector near the sharp second leg of the connector element when the body and the cover are completely fitted together.

They also hold the body and the cover in the open position so that at least one wire can be inserted through the connector between the body and the cover into the end of the body that is open for entry and exit of the wire, and the body and the cover are completely clamped together. It is formed as a latch member of the support for keeping in position.

When the cover and the body are fitted together, the cover exerts a force on the wire into each slot in the contact element and at least one wire against the sharp leg of the contact element acting as a cutting blade that cuts the end of the wire at the same time. . The connector end sealing film blocks the end of the body after the end of the wire has been cut.

Referring to the implementation of FIGS. 1 to 7, the wire connector of the present invention is inserted into the insulating body 10, the U-shaped elastic conductive wire connector element 12, and the body 10, which are hollow and open at the top. It consists of an insulating cover 14 formed to be.

The body 10 extends from the bottom wall 15 between the bottom wall 15, a pair of generally parallel side walls 16 generally extending vertically from the bottom wall, and between the side walls 16 at one end of the body. It has a finished end wall 17. The upper edge 18 of the body end wall 17 is inclined at a sharp angle with respect to the bottom wall 15. The end of the body opposite the end wall 17 is open for entry and exit of the insulated wire 20. Near the open end of the body 10, two rows of dividers 21 and 22 are arranged horizontally along the body to define three parallel wire entry and exit paths that are weaker or narrower than the wired wires 20. It is extended to 15).

The legs 24 and 25 of the wire connector element 12 having a shape are wide and thin. One leg 24 is formed of three wire connecting slots 27 extending from the top of the leg 24 toward the bottom of the U.

The second leg 25 is sharply cut along its upper edge. The connector element 12 is defined by the bottom portion of the U on the magnetic surface wall 15 of the body, the sharply cut legs 25 extending and abutting over the body end wall 17, and the dividers 21 and 22. It is located in the body 10 with wire connection slots 27 arranged in the passageway. The waterproof grease 28 is filled in the empty portion of the body between the divider 22 and the end wall 17 including the space in the U of the connector element 12.

The cover 14 is formed to fit in the body 10 between the body side walls 16. The cover is formed with a pair of parallel transverse slots 29 and 30 which can accommodate the legs 24 and 25 of the connector element 12, respectively.

It also supports three longitudinal wire supports aligned with the slots 27 of the wire connector element 12 to lead the wires 20 into the slots 27 when the cover 14 is fully inserted into the mother body. It is formed as a chanel 32. It is formed as a sharp edge 34 to contact the inclined upper edge 18 of the body end wall 17. The edge 34 is in contact with the inclined upper edge 18 when fully inserted into the body 10 with the cover 14 to close the end of the connector.

The body 10 and the lid 14 are defined by longitudinal ribs 36 and 37 on the inner side of both body side walls 16 and ribs 38 and 39 on the outside of the side lid side walls. The paper is formed as a latch member of the foot. In the fully open position of the connector, the lower lip 39 of the lid is fitted between the lip 36 and 37 of the body, as illustrated in FIGS. 1, 2 and 3. In this position, the wires 20 can slide into the wire support channel 32 between the body 10 and the cover 14.

The cover can then be inserted into the body by pressing the cover with the hand and brought to the position immediately before the detention of FIG.

This means that the wire 20 of its latches 38 and 39 are placed on both sides of the body ribs 36 and 37 and its chanel 32 is insulated relative to the connector element 12. Pressure is applied to move the lid to such a position that the wires are held in their position in the connector.

The cover is fully tightened into the body by a tool such as a plymer that inserts the cover 14 into the body 10 until its upper lip 38 lies between the body's lips 36 and 37. To the positions illustrated in FIGS. 5, 6 and 7. As the lid is moved to the full detent position, the channel 32 moves into the divider 21 and 22 into the slot 27 of the connector element 12 and the sharply cut cutting leg 25 of the connector element. This leads to the wire 20.

In the dividers 21 and 22, the insulator of the electric wire 20 becomes sawtooth and acts as a strain reeling.

In the slot 27, as the cover exerts a force on the end of the wire against the sharply cut leg 25 to cut the end of the wire, the insulation is drilled to make a connection with the conductor. The inclination of the upper edge 18 of the body end wall 17 acts to dislodge the ends of the wires from the connector when they are cut. The grease 28 is ejected around the wire connection as the lid 14 is moved from the position just before the shaft to the complete shaft position. The ends of the wires are cut and extracted before the cover reaches the fully deflated position and then grease is injected to fill the space emptied by the ends of the cut wires, making the connection water resistant.

Referring to the embodiment of the present invention illustrated in FIGS. 8 to 12, this embodiment is also hollow and the top of the insulating body 50, the U-shaped elastic conductive wire connector element 52 and the insulating cover ( 54).

The parts in this embodiment are essentially opposite to the second embodiment such that the body 50 is fitted into the cover 54 instead of the cover being fitted into the body.

The body 50 includes a bottom wall 55, a pair of generally parallel side walls 56 extending vertically from the bottom wall to the general war, and between the bottom wall 55 at one end of the body between the side walls 56. It has an extended end wall 57. The upper edge 58 of the body end wall 57 is inclined at a sharp angle with respect to the bottom wall 55.

The end of the body 50 opposite the end wall 57 is open for entry and exit of the wire 60. Near the open end of the body 50, the two rows of dividers 61 and 62 form a bottom wall 55 along the transverse line of the body to define the passage of three parallel wires slightly narrower than the wire 60. Extends from

The legs 64 and 65 of the U-shaped wire connector element 52 are wide and thin. One leg 64 has three computer-connected slots extending from the top of the leg 64 toward the bottom of the U. It is formed as the tread 67.

The second leg 65 is aligned with the wire connecting slot 67 of the second leg 64 and sharply cut along the upper edge. The four stabilizing rods 66, which are formed as barbed ends, extend from the upper edge of the leg 65, and one rod 66 extends through the connector element 52 to each side of the wire position. The connector element 52 is located in the body 50 by a sharply cut leg 65 extending over and in contact with the bottom portion of the U on the bottom wall 55 of the body, the body end wall 57. The waterproof grease 68 is filled in the hollow of the body between the divider 62 and the end wall 57 including the space in the U of the connector element 52.

The cover 54 is hollow so that the body 50 can be fitted and the top is open. The cover is formed by parallel transverse slots 69 and 70 for accommodating the legs 64 and 65 of the connector element 52, respectively, and the four holes 71 are formed of the connector element 52. It is formed to accommodate the rod 66 extending from the sharply shaved leg 65.

Narrow rib 72 extends across slot 69 in line with each of the three wire connecting slots 67 to press-fit into slot 67 when fitting body 50 into cover 54. Support the wire 60 to be. A similar lip 73 is provided to insert the wire 60 between the dividers 61 and 62. At the end of the cover 54 near the wire entry of the body 50, the cover divides to assist and guide the insertion of the wire 60 through the connector between the body 50 and the cover 54 in the fully open position. It is formed by the wire insertion opening 75 aligned with the wire passage between the 61 and 62 and the wire slot 67 of the connector element 52.

The body 50 and the lid 54 are of prosthetic teeth defined by the outer longitudinal lips 76 and 77 of both body side walls 56 and the inner lips 78 and 70 of the both cover side walls. It is formed as a latching member.

In the fully open position of the connector, the lower lip 77 of the body fits between the lip 78 and 70 of the lid as illustrated in FIGS. 8-10. In this position, the wire 60 can slide into the wire insert 75 through a connector between the body 50 and the cover 54.

The body 50 is pushed into the lid 54 by fingering to go to a position just before the side chains where the latches 76 and 77 of the body are placed on both sides of the lids 78 and 79. In this position, the body 50 and the cover 54 frictionally couple the wires 60 therebetween. The visible end of the stabilizing rod 66 of the connector element 52 bites into the side wall of the lid 71 to help keep the body and lid in this position.

The body is constructed by means of a plier-shaped tool that fits the body 50 into the cover 54 until its upper lip 76 is placed between the lips 78 and 79 of the cover. It is fully tightened into the lid to the position illustrated in 12 degrees. As the body moves to the fully retracted position, the wire insertion lip 73 rises the wire into the splitters 61 and 62, and the wire insertion lip 72 moves the wire 60 into the connector element slot 67. The cutting leg 65, which is led and sharply cut, takes the electric wire and moves into the slot 70. In the dividers 61 and 62, the insulation of the wire 60 is provided as a strain relief with tooth marks.

In the slot 67 a connection is made with the conductor as the insulation is perforated so that the cover exerts a force on the end of the wire against the sharp leg 65 which cuts the end of the wire.

The stabilizing rod 66 prevents the deflection of the sharp cutting leg 65 by the wire and its barbed end bites into the side wall of the hole 71 of the cover so that the body and the cover remain in the fully locked position. Will help.

The inclination of the upper edge 58 of the body end wall 57 causes it to be expelled from the connector when the end of the wire is cut. When the body 50 moves from the position immediately before the shaft to the complete shaft position, the grease 68 is ejected around the wire connection. The ends of the wires are cut and extracted before the cover reaches the fully deflated position so that grease is injected into it to fill the area emptied by the ends of the cut wires.

In the embodiment of FIGS. 8-12 the inclined wall 58 of the body 50 is not in contact with any part of the lid 54 in the fully deflated position. Thus, the end of the connector is not completely closed in the same manner as in the first embodiment.

For this reason, the swing door 81 turns round to close the end of the connector near the cutting leg 65 of the connector element.

The wedge shaped latch projection 83 extending from the edge of the door 81 fits snugly in the latch hole 84 in the edge wall of the lid 54 to keep the body in the closed position sealing the end of the connector. .

Many other variations of the present invention will be apparent to those skilled in the art. For example, a wire receiving slot and a cutting blade that form each leg of the connector element and provide a beveled end wall and a sealing door at each end near the cutting edge to accommodate one wire from each end. Connectors may be made.

As another example, in a fully open position, a two-wire tab connector is provided such that through wires enter from one side of the connector and only the end of the wire has means such as cutting blades, beveled end walls, and doors for sealing the connector ends near the cutting eggs. Can be made.
