Description

Technical Field

[0001] The present invention relates to the field of inverters, and particularly to a wall-through connector. Background Art

[0002] For the multi-core terminal wall-through connectors on the current market, the two cables to be connected are generally fixed at both ends of the connector respectively. This installation method will extend the lengths of the two cables respectively, increasing the manufacturing cost. In addition, the more connection points or the longer the conductive wire length, the more likely quality problems will occur, which is not conducive to the long-term and stable use of the wall-through connector. If it is possible to observe whether each component is installed in the correct position, it plays an important role in improving the installation efficiency and the installation quality. In addition, restricting the locking component from falling off facilitates the pre-installation of the product by the manufacturer, and it also has a very important role in the stable and durable use during the installation and use process of the product.

[0003] Generally, a protective cover is sleeved on the wall-through connector, which more plays the role of dust prevention and electric shock prevention. Generally, for safety reasons, the protective covers on the current market are either non-removable or difficult to remove, or the detachable method is not firm and is prone to loosening after long-term use, thus posing a threat to personal safety; but at the same time, the detachable protective cover generally has difficulty in achieving a sealed design and cannot prevent water well. If water vapor enters, it will cause equipment failure at the least and serious safety accidents such as fires at the worst. It is very difficult to combine several functions mentioned above, such as dust prevention, electric leakage prevention, detachable, preventing misoperation, anti-loosening and sealing, etc.

[0004] Therefore, in view of the above existing technical problems, it is necessary to provide a new technical solution. Summary of the Invention

[0031] Compared with the prior art, the wall-piercing connector described in this patent has at least one or more of the following beneficial effects in its technical solution:

[0032] (1) The first cable and the second cable are installed on the same wiring hole of the conductive plate, so that the first cable and the second cable have a power sharing connection point. The purpose of this design is to greatly save the length of the conductive plate and the cost of the conductive plate. Compared with the conventional technology, the conductive plate of this embodiment saves half of the cost, greatly reducing the manufacturing cost of the through-wall connector. Therefore, this through-wall connector is more acceptable and usable by users, which helps with its wide promotion and use. In addition, reducing the connection points and wire lengths also reduces the problems of connection point loosening or other faults, which is beneficial to the long-term stable operation of the terminal block and further extends the service life of the terminal block.

[0033] (2) It is convenient to use. A clip is provided. The first cable can be inserted into the jack at the device end first, and the clip can be detachably installed on the insulating seat body. On the one hand, the tongue plate of the clip abuts against the conductive plate, and the outer end of the clip is aligned with the outer end of the insulating seat body. By observing whether the wiring plate of the conductive plate abuts against the stop surface, whether the tongue plate of the clip abuts against the wiring plate of the conductive plate, and whether the outer end of the clip is aligned with the outer end of the insulating seat body, it can be directly observed whether the conductive plate is installed in the correct position and whether the clip is installed in the correct position. It can be directly judged, the operation is simple, the assembly is relatively easy, and the installation efficiency is improved. On the other hand, the shielding plate of the clip covers the mounting hole opening, so that the bolt sleeved with the first cable and the conductive plate is fixed in the mounting hole and pre-installed in place. This not only facilitates the semi-finished product of the terminal block wiring to be shipped to customers, and the customer only needs to install the second cable at the outer end after getting the device, but also can improve the firmness during the locking installation and use of the terminal block and extend the service life.

[0034] (3) It can also connect functional cables, such as temperature measurement wires, etc., to increase the functional diversity of the terminal block; ribs are provided on both sides of the terminal block to make the sleeved protective cover play an anti-misoperation role, avoiding misinstallation caused by operation mistakes, thus bringing unnecessary losses.

[0035] (4) The terminal block is also provided with an annular sealing groove and an annular groove that can nest the sealing ring, so that both between the terminal block and the device end and between the terminal block and the protective cover can be sealed, avoiding water seepage and liquid seepage, causing corrosion and rust of the cable, etc., which helps to improve the service life of the terminal block.

[0036] (5) The connection part of the protective shell adopts a mechanical stop design, and a stop spring piece is provided at its connection end to prevent the wire locking sleeve from accidentally loosening or loosening after long-term use and aging, improving the safety and stability of the equipment use. In addition, a pressing protrusion is also provided. After locking, the wire locking sleeve can be disassembled by manually pressing, without the need to use auxiliary tools for disassembly, which is convenient for operation and greatly improves the convenience of use, making it more convenient for users.

[0037] (6) The thread-locking sleeve is provided with a waterproof film and is sealed around the second cable to be installed. In addition, sealing strips are arranged at intervals on the wire-sealing claws. With a flexible design, it can seal the second cable to achieve overall waterproof sealing. At the same time, it can be compatible with more specifications of the second cable, which is both safe and practical.

[0038] (7) The hook provided on the clamping plate of the waterproof housing can only be unlocked with tools, that is, mechanical unlocking, to prevent misoperation from bringing danger to personal safety or hindering the normal operation of the equipment. This design is safer.

As Figure 1-2 shown, the wiring base 1 and the protective cover 5 are coaxially arranged. A plurality of first cables 31 and a plurality of second cables are installed in the wiring base 1. The first cables 31 and the second cables are installed on the same wiring hole 211 of the conductive plate 2, so that the first cables 31 and the second cables have a power sharing connection point. The purpose of this design can greatly save the length of the conductive plate and the cost of the conductive plate. Compared with the conventional technology, the conductive plate of this embodiment saves half of the cost, greatly reducing the manufacturing cost of the wall-piercing connector. Therefore, this wall-piercing connector is more acceptable and usable by users, which helps to widely promote and use it; in addition, reducing the connection points and the wire length of the conductive wires also reduces the loosening failure of the connection points or other fault problems, which is beneficial to the long-term stable operation of the wiring base and further extends the service life of the wiring base; on the other hand, the provided protective cover has a sealing property. The protective cover itself has a sealing property, is hermetically connected to the insulating seat body 10, and is sealed with the second cable when the second cable extends into the protective cover, and the insulating seat body 10 is hermetically fixed to the equipment end. The all-round sealing design can better protect the second cable from being corroded and rusted by the environment, and can better extend the service life of the equipment and the second cable. This embodiment takes a 5-core 50A wall-piercing connector as an example to elaborate on the solution. The 5-core 50A wall-piercing connector is mainly used for cable connection on the inverter.

A plurality of shielding grooves 124 are formed at one end of the insulating seat body 10 away from the jack 11. The axial direction of the shielding grooves 124 is the same as the axial direction of the insulating seat body 10. The shielding grooves 124 correspond to the wiring slot 12 one by one. The mounting holes 123 are all communicated with the shielding grooves 124 and the wiring slot 12.

[0073] The locking member includes a bolt and a nut. The bolt includes a bolt tail end which is non-circular. A receiving hole 1231 matching the bolt tail end is formed at the bottom of the first wire groove 122. The receiving hole corresponds to the mounting hole 123. The first wire groove 122 and the shielding groove 124 are communicated through the receiving hole 1231. The bolt penetrates through the mounting hole 123 and sequentially passes through the receiving hole 1231, the first wiring nose, the wiring hole 211 and the second wiring nose. The bolt tail end is received in the receiving hole 1231. The second wiring nose is sleeved on the bolt.
