Description
Technical Field
The invention relates to the technical field of electronics, in particular to a wiring terminal, an electric device provided with the wiring terminal, a manufacturing method of the wiring terminal and a connecting method of the wiring terminal.
Background
At present, in the fields of power transmission, signal transmission and the like, it is necessary to connect a wire and power equipment by using a terminal. The existing connecting terminal is made of copper materials, so the existing connecting terminal is called a copper connecting terminal.
As shown in fig. 1 and 2, a conventional copper connection terminal includes two parts, a first conductive part 1 and a second conductive part 2, of an integrated structure in which:
the first conductive part 1 of the copper wiring terminal is tubular and is provided with a mounting hole 11;
after the cable 41 is inserted into the mounting hole 11 along the axial direction of the mounting hole 11 on the first conductive part 1 of the copper terminal as shown in fig. 2, the first conductive part 1 is pressed, so that the cable 41 and the first conductive part 1 are fixedly connected and electrically connected;
the second conductive part 2 of the copper wiring terminal is flat and flaky, a through hole 21 is formed in the second conductive part 2, and the maximum extension direction of the second conductive part 2 is aligned with the axial direction of the mounting hole 11.
The contact strip of the electrical component connected to the copper terminal on the electrical device is generally a flat copper strip 31 for conducting electricity as shown in fig. 2, and the copper strip 31 has a connecting hole. During specific connection, the copper bar 31 and the copper wiring terminal which are connected together can transmit electric energy by using bolts to enable the copper bar 11 and the copper bar 31 to be in close contact with each other through the through holes 11 of the copper wiring terminal and the connecting holes of the copper bar 31 to form electric connection.
In the power supply and distribution system of enterprise, because the high-speed development of enterprise, electrical equipment is more and more in the enterprise, and then leads to the power consumption demand of enterprise bigger and bigger, and the power consumption demand of enterprise is more and more can't be satisfied to the power supply and distribution equipment efficiency, though, power supply and distribution equipment efficiency also improves, but the improvement of power supply and distribution equipment efficiency seems hysteresis a bit with the increase of enterprise power consumption demand comparatively. Many enterprises have the problems, so that temporary power distribution and temporary cable laying are often needed. To meet the power requirements of enterprises, most of the cables used in enterprises are cables capable of transmitting higher voltage or current (e.g., cross-sectional area is in120mm2The above cables) such cables are generally inflexible.
As shown in fig. 2, since the number of copper bars 31 for connecting cables 41 on the power equipment is limited, and there is only one connecting hole on the copper bar 31, it is often necessary to connect a plurality of cables 41 on one copper bar 31. When the copper bar 31 is connected, the bolt 61 needs to be inserted into the connecting hole of the copper bar 31, then the through holes 21 of the second flat conductive parts 2 of the plurality of copper terminal strips connected with the cable 41 are sleeved on the bolt 61, after the through holes 21 of the second flat conductive parts 2 of the plurality of copper terminal strips are sleeved on the bolt 61, the through holes 21 of the second flat conductive parts 2 of the plurality of copper terminal strips overlap, in order to ensure that the plurality of flat second conductive parts 2 and the copper bar 31 form reliable electrical connection, the second conductive parts 2 and the copper bar 31 and the plurality of flat second conductive parts 2 must be in close contact, and when the plurality of flat second conductive parts 2 are in close contact, the first conductive part 1 in a tubular shape of the copper terminal strip is obstructed by the first conductive part 1 in a tubular shape of another copper terminal strip adjacent to the first conductive part when the first conductive part 1 rotates around the bolt 61, as a result, the first conductive parts 1 having a tubular shape cannot be overlapped with each other, and the first conductive parts 1 having a tubular shape of each copper terminal are scattered in a plurality of directions. At this time, the bolts 61 are tightened to ensure the close contact between the second conductive part 2 and the copper bar 31 and between the adjacent second conductive parts 2, so that the copper bar 31 can be electrically connected to the plurality of cables 41 through the plurality of copper connection terminals.
Since the first conductive part 1 of the tubular copper terminal is spread out in a plurality of directions, the cables 41 connected to the copper terminal are also spread out in a plurality of directions, whereas the cable outlet of the housing of the electric power equipment in the related art is usually opened in one direction on the housing of the electric power equipment, and in order to make the plurality of cables 41 all protrude from the cable outlet of the housing and keep the cables 41 in parallel, the following two installation methods are mainly used in the related art: ,
the first installation mode is as follows: sleeving the copper wiring terminal connected with the cable 41 on the bolt 61 and screwing the bolt 61 tightly to ensure that the second conductive parts 2 are tightly contacted with the copper bars 31 and the adjacent second conductive parts 2, and then bending the cables 41 scattered in multiple directions towards the cable outlet direction on the shell to ensure that the cables 41 are distributed in parallel along the cable outlet direction, wherein the installation mode bends the cables 41 connected with the copper wiring terminal into a bent shape as shown in fig. 2;
the other installation mode is as follows: after the cables 41 connected with the copper terminals are arranged in parallel, the cables extend into the housing from the outside of the cable outlet of the housing, and the second conductive parts 2 of the copper terminals are connected to the copper bars 31 by being sleeved on the bolts 61. Before the copper wiring terminal connected with the cable 41 is sleeved on the bolt 61 and the bolt 61 is screwed, the cable 41 connected with the copper wiring terminal is bent into a bent shape as shown in fig. 2, and then the through holes 21 of the second conductive parts 2 of the copper wiring terminals on the cable 41 which are originally distributed in parallel along one direction are overlapped with the connecting holes on the copper bars 31, so that the electric connection between the cable 41 and the copper bars 31 is realized.
The inventor finds that the prior art has at least the following problems in the process of implementing the invention:
in the prior art, the first mounting method and the second mounting method have different processes, but have the following common problems: the cable 41 shown in fig. 2 needs to be bent during installation, and the operation of bending the cable is usually laborious because the existing cable, especially the cable transmitting a large voltage or current, is not easy to bend, which in turn causes the operation of connecting the cable through the copper terminal in the prior art to be laborious, and even affects or destroys the electrical connection.
