Description

Technical Field

[0001] The utility model relates to a sealed cable for a submersible sewage pump which is easy to connect. Background Art

[0002] Submersible sewage pumps are designed for underwater use and are used to transport liquids containing hard solids, fibers, and particularly dirty, sticky, and slippery liquids. Therefore, submersible sewage pumps require sealed cables to prevent external liquids from entering the connection between the cable and the pump body, causing short circuits and other faults.

[0003] Most existing cables and pump body connecting lines adopt a twisted connection method, that is, the wire cores to be connected to each other are twisted and tightened. Although this method can complete the connection work between the cable and the pump body connecting line, it is relatively troublesome and difficult to achieve a quick connection process. In addition, this connection method has low strength and is easily detached due to external factors (such as pulling, water impact force), thereby affecting the normal operation process of the submersible sewage pump.

[0004] Therefore, it is necessary to provide a sealed cable for a submersible sewage pump that is easy to connect to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a sealed cable for a submersible sewage pump which is easy to connect, so as to solve the problems raised in the above background technology.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] The cam is connected to the upper and lower ends of the cam, and the cam is connected to the bottom end of the cam, and the cam is connected to the bottom end of the cam.

[0008] Preferably, an annular mounting seat is fixedly sleeved on the outer wall of the rubber sleeve, and a mounting hole is provided on the annular mounting seat.

[0009] Preferably, the inner surface of the limiting groove fits the outer surface of the limiting block.

[0010] Preferably, rubber protrusions are provided on both sides of the inner wall of the rubber sleeve, and grooves are provided on both sides of the upper connecting seat, and the grooves are adapted to the rubber protrusions.

[0011] The beneficial effect of the present invention is as follows: the cable main body is vertically lowered close to the pump body connecting line. During this process, the two movable plug-ins at the bottom of the upper connecting seat are respectively inserted into the corresponding slots. When the movable plug-in block moves downward, the sliding cooperation between the first inclined surface and the second inclined surface will drive the limit block to slide in the slide groove. At this time, the spring is compressed until the movable plug-in block is completely entered into the slot. The reaction force after the spring compression drives the limit block to be inserted into the limit groove, thereby completing the connection process of the upper connecting seat and the lower connecting seat, and finally completing the limiting and fixing process of the cable main body and the pump body connecting line. At this time, the copper terminal at the opposite end of the cable main body and the pump body connecting line fits each other to complete the electrical connection process of the cable main body and the pump body connecting line. Afterwards, the rubber sleeve is sleeved on the outside of the connection between the cable main body and the pump body connecting line, and then resin is filled into the rubber sleeve to complete the sealing work of the cable line. Through the above-mentioned setting, the connection between the cable main body and the pump body connecting line can be completed quickly, saving time and effort, and by moving the plug, the limit block, the slide groove, the first inclined surface, the second inclined surface and the slot, the limit fixing process after the cable main body and the pump body connecting line are connected can be completed, thereby preventing the two from being separated due to external factors, thereby ensuring the normal operation of the submersible sewage pump.

[0017] See Figures 1 to 3 The illustrated embodiment shows a sealed cable for a submersible sewage pump that is easy to connect, comprising a cable body 1 and a pump body connecting line 2. The cable body 1 and the pump body connecting line 2 are both provided with copper terminals 3 at opposite ends. The cable body 1 is sheathed with a rubber sleeve 4. The outer walls of the cable body 1 and the pump body connecting line 2 at opposite ends are respectively fixedly sheathed with an upper connecting seat 5 and a lower connecting seat 6. Both sides of the bottom of the upper connecting seat 5 are provided with movable plug-in blocks 7. Both sides of the top of the lower connecting seat 6 are provided with slots 8. The slots 8 are It is suitable for plugging in the movable plug-in block 7. One end of the slot 8 is connected to a slide groove 9. A limit block 10 is slidingly arranged in the slide groove 9. A spring 11 is connected between the limit block 10 and the inner wall of the slide groove 9. A first inclined surface is provided at the bottom of the movable plug-in block 7. A second inclined surface is provided at one end of the limit block 10. The second inclined surface slides with the first inclined surface. A limit groove 12 is provided on one side of the movable plug-in block 7. The limit groove 12 is adapted to the limit block 10. Resin 13 is provided inside the rubber sleeve 4.
