The present invention relates to a wire connector, and more particularly to a wire connector for a plurality of wires that are inserted therein to electively connect each other.
Wire connector was founded in a slice type connecting terminal (model JTSL-1022) which was invented by Phoenix company, German, in 1928. Since then, a prototype of connector has changed into a connective wire connector with different kind of terminal. For the purpose of connecting or breaking the connection between a plurality of wires with the same or different kind of terminal according to the needs, the wires neither have to be welded or twisted nor using special connector for different kind of terminal additionally. In addition to reducing the cost of processing procedure for connecting the wires, it can increase the freedom of interior design and reduce the working time for assembling wires as well.
The connector can be classified into plug type, fencing type, spring type, track type, H style through-wall type, WMSTB type, and so on. Applying to the industry of lightening, communication and security; mostly used in variable frequency, explosion protection, digital control panel, door security, sensor, PLC program controller, appearance of instrument, power, and servo driver.
A primary object of the present invention is to provide a wire connector for strengthening the function of fixing shift levers while the wires are inserted or not be inserted into the wire connecter, and preventing the shift lever from moving when the wire connector is crashed by an external force. Further, providing a voice and an operation sense for the user hand to know whether the shift lever is fixed firmly.
Another object of the present invention is to provide the fixed devices in the moving track of the shift lever for simplifying the fixing steps of inserting the end of wire and increasing the convenience of manual operation. Thereby, reducing the connection steps of the wires and the equipment cost corresponding to the connection steps; meanwhile, increase the convenience for connecting, distributing or repairing the wires.
To achieve the above and other objects, the wire connector for a plurality of wires being inserted along an inserting direction, comprising: a cover, a conductor and a plurality of shift levers.
The cover has a plurality of inserting holes along the inserting direction and a receiving space communicates with the plurality of inserting holes.
The conductor is assembled in the receiving space of the cover, and comprises a conductive portion that contacts the wire, and a plurality of elastic portions that are located in an extended position of each inserting hole respectively, so that the wire will be clamped by the conductive portion and elastic portion after inserting the interior of the cover.
The shift levers are pivoted on the cover and swing between a first position which non-contacts the elastic portion and a second position which presses the elastic portion for generating a deformation.
The wire connector further comprising: A first fixed device is formed in the first position for fixing the shift levers; and a second fixed device is formed in the second position for fixing the shift levers.
In the preferred embodiment, the first fixed device comprises a first block being formed with one of the shift levers and the cover, and a first groove being formed with another of the shift levers and the cover for corresponding the position of the first block.
the second fixed device is formed with the group consisting of both of the shift levers and the cover, both of the shift levers and the elastic portions, and triple of the shifts, the cover and the elastic portions.
In one preferred embodiment, the second fixed device comprises a plurality of shift bars are extending from the opposite sides of the shift levers, and a plurality of slots are dividedly formed on the cover for corresponding the position of the shift bars.
The second fixed device also comprises a second block being formed with one of the shift levers and the cover, and a second groove being formed with another of the shift levers and the cover for corresponding the position of the second block.
The second fixed device further comprises a third block being formed with the elastic portion and a pressure portion being formed with the shift lever for corresponding the position of the third block.
From the above description, the wire connector of the present invention is characterized in the first fixed device and second fixed device are formed in the swinging track of the shift levers for fixing the shift levers. Otherwise, the first fixed device and the second fixed device are constructed by both or three of the shift levers, elastic portion and cover. So that the present invention can strength the fixing force of the shift lever in the first position and the second position and provide a sense of user hand to know whether the shift lever is fixed in a right position.
The wire connector can simplify the steps of inserting the wire and increase the convenience for user operation. In addition to decrease the connection process between conductive structures and the equipment cost for corresponding with the connection process.
The structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, wherein:
The present invention will now be described with a preferred embodiment thereof and by referring to the accompanying drawings.

The cover 3 is composed of a first cover member 32 and a second cover member 33. Both of the first cover member 32 and the second cover member 33 are assembled with each other along the inserting direction 20. A surface of the first cover member 32 has a plurality of second blocks Q1 for corresponding the extension position and quantity of the inserting holes 30. A plurality of slots 320 are formed around the second blocks Q1 along the inserting direction 20. Furthermore, a surface of the second cover member 33 has a first block P1, and the interior of the second cover member 33 forms a plurality of pivoted holes 330 perpendicular to the inserting direction 20. The shift lever 5 is pivoted on the pivoted holes 330.
The conductor 4 is assembled in the receiving space 31 which is inside of the cover 3, and composed of a conductive portion 40, a connect portion 41 and a plurality of the elastic portions 42 which are connected with the connect portion 41. In a preferred embodiment, the conductive portion 40 is designed in a form as a conductive plate. The connect portion 41 comprises a penetrative portion 410, an upper connect portion 411 and a lower connect portion 412. The penetrative portion 410 is formed on an extension path of the inserting direction 20, and substantially vertical to the inserting direction 20. The penetrative portion 410 has a plurality of penetrative holes 4100 which are corresponding to the position and quantity of the inserting holes 30.
Moreover, the upper connect portion 411 and the lower connect portion 412 are formed at two opposite sides of the penetrative portion 410 respectively. Both of the upper connect portion 411 and the lower connect portion 412 are substantially parallel to the inserting direction 20. In a preferred embodiment, the upper connect portion 411 can be assembled to the conductive portion 40 by a fasten way. The elastic portions 42 are bended (U type or V type) by a metal material, and the lower connect portion 412 further comprises a third block 42 on a surface adjacent to the wire 1.
Before the end of the wire 1 inserts the receiving space 31, the lower connect portion 412 is pressed by the shift lever 5 for changing the angel between the lower connect portion 412 and the lower connect portion 412. The opposite surfaces of the wire 1 are clamped and fixed by the upper connect portion 411 and the lower connect portion 412, so that the wire 1 can penetrate into the penetrative hole 4100.
