Description

Technical Field

[0001] The present invention relates to the technical field of electrical connectors, and in particular to a highly sealed waterproof electrical connector. Background Art

[0002] In modern electrical and electronic systems, electrical connectors play a vital role. They not only ensure stable connections between circuits, but also provide necessary protection in various environments. Especially in high humidity, underwater or other harsh conditions, the requirements for electrical connectors are not only to achieve reliable electrical connections, but also to have excellent waterproofness and sealing to prevent the intrusion of moisture and other contaminants.

[0003] The traditional way of connecting electrical connectors to cables usually requires manual stripping of the cable sheath to directly expose the conductor for connection. Although this method can provide a good contact area, the operation is complicated and time-consuming, and it increases the difficulty and cost of construction. Piercing connectors are gradually becoming popular as a solution that does not require wire stripping. This type of connector establishes an electrical connection through a built-in needle that directly penetrates the cable insulation layer, simplifying the installation process. However, since the connection point formed by the needle is small, when encountering a large current load or vibration environment, poor contact may occur, affecting the quality of signal transmission. In addition, relying solely on the needle for connection may not guarantee sufficient pressure and contact area in some cases, especially in environments with frequent temperature changes or vibrations, which may reduce the overall reliability of the system. Summary of the Invention

[0004] In view of this, the present invention provides a highly sealed waterproof electrical connector, which can solve the problem that when traditional electrical connectors are connected to cables, the cable sheath needs to be manually stripped, which is not only complicated and time-consuming to operate, but also increases the construction difficulty and cost.

[0031] See Figure 1-Figure 3 As shown, the sealing mechanism includes a sealing strip 601 and an arc-shaped plate 602; a sealing strip 601 is provided on the top of the connecting frame 1, and both ends of the sealing strip 601 are connected to the sealing ring 5. The sealing strip 601 is used to seal the gap between the rotating frame 4 and the connecting frame 1 when the rotating frame 4 is covered on the top of the connecting frame 1; a curved plate 602 is provided on the top of the sealing ring 5. When the rotating frame 4 is covered on the top of the connecting frame 1, the curved clamping plate on the rotating frame 4 will apply pressure to the sealing ring 5, so that the sealing ring 5 shrinks to the middle until it is close to the outer surface of the cable, thereby sealing the gap between the sealing ring 5 and the outer surface of the cable.

[0032] See Figure 2 and Figure 3 As shown, the limiting mechanism includes a plastic hook plate 701 and a limiting card plate 702; the two plastic hook plates 701 are symmetrically arranged on the upper side of the rotating frame 4; the two limiting card plates 702 are symmetrically arranged on the upper right side of the connecting frame 1, and the limiting card plate 702 is used to limit the plastic hook plate 701.

[0033] See Figure 5As shown, the lifting mechanism includes a movable frame 1001 and a first spring 1002; a movable frame 1001 is slidably arranged between the upper parts of the two support plates 8 close to each other, and the movable frame 1001 is divided into an upper and lower part, the upper part is made of insulating material, and the lower part is made of conductive material, the conductive sheet 3 is connected to the lower left side of the movable frame 1001, the pressure block 11 is connected to the lower right side of the movable frame 1001, the tool 12 is connected to the lower right side of the movable frame 1001, the tool 12 is located above the pressure block 11, the contact sheet 13 is connected to the lower right side of the movable frame 1001, the contact sheet 13 is located above the tool 12, and the contact sheet 13 is electrically connected to the conductive sheet 3 through the conductive material on the movable frame 1001; a first spring 1002 is connected between the upper side of the movable frame 1001 and the upper side of the support plate 8 on the rear side.

[0034] See Figure 6 and Figure 7 As shown, the locking mechanism includes a connecting plate 1401, a strip card plate 1402, a second spring 1403 and an unlocking plate 1404; two connecting plates 1401 are provided at the bottom of the movable frame 1001, and the lower right side of the connecting plate 1401 is set as an inclined surface; a strip card plate 1402 is slidingly provided between the lower right parts of the two support plates 8 close to each other, and the left side of the strip card plate 1402 is set as an inclined surface, and the strip card plate 1402 is used to limit the connecting plate 1401; an unlocking plate 1404 is connected to the right side of the strip card plate 1402, and the top of the unlocking plate 1404 is set as an arc surface; a second spring 1403 is connected between the left side of the unlocking plate 1404 and the support block 9.

[0035] When in use, extend the end of the cable into the connecting frame 1 through the inner side of the sealing ring 5, so that the end of the cable enters the groove 901 of the support block 9, until the end of the cable passes through the groove 901 and moves to the bottom of the pressing block 11, then press the movable frame 1001 to move downward, the first spring 1002 is compressed, so that the movable frame 1001 drives the conductive sheet 3 to deform, and the movable frame 1001 drives the pressing block 11, the tool 12, the contact sheet 13 and the connecting plate 1401 to move downward, when the pressing block 11 contacts the end of the cable, the pressing block 11 will bend the end of the cable and make the end of the cable close to the left side of the support block 9, when the tool 12 contacts the surface of the cable When the insulating layer of the cable comes into contact with the blade 12, the blade 12 will peel off the insulating layer on the outer surface of the cable to expose the conductor inside the cable. When the contact piece 13 comes into contact with the conductor inside the cable, the conductor inside the cable will be connected to the external wire 2 through the contact piece 13 and the conductive piece 3. When the inclined surface on the connecting plate 1401 comes into contact with the inclined surface on the left side of the strip card plate 1402, the connecting plate 1401 will squeeze the strip card plate 1402 and the unlocking plate 1404 to move to the right, and the second spring 1403 will stretch. When the connecting plate 1401 passes over the strip card plate 1402, the second spring 1403 returns to its original state, and the second spring 1403 drives the strip card plate 1402 and the unlocking plate 1404 to move to the right. 4 is moved to the left to reset, so that the strip card plate 1402 limits the connection plate 1401, thereby locking the positions of the movable frame 1001, the pressure block 11, the cutter 12 and the contact piece 13. At this time, the contact piece 13 just presses the cable conductor it contacts into the arc groove 902 of the support block 9, and then pushes the rotating frame 4 to rotate and close, so that the rotating frame 4 contacts the sealing ring 5, so that the rotating frame 4 and the sealing ring 5 seal the components in the connection frame 1. At the same time, the arc clamping plate on the rotating frame 4 contacts the arc plate 602, which can press the sealing ring 5 on the rotating frame 4 to shrink the sealing ring 5 to the middle until it is close to the cable surface. This seals the gap between the sealing ring 5 and the outer surface of the cable, thereby preventing water from entering the connection frame 1 through the gap between the sealing ring 5 and the outer surface of the cable. When the rotating frame 4 rotates to close, the rotating frame 4 drives the plastic hook plate 701 to rotate synchronously. When the plastic hook plate 701 rotates to contact the limiting card plate 702, the limiting card plate 702 squeezes the plastic hook plate 701 to deform. When the plastic hook plate 701 passes the limiting card plate 702, the plastic hook plate 701 returns to its original shape. At this time, the limiting card plate 702 clamps the plastic hook plate 701, thereby limiting the position of the plastic hook plate 701 and the rotating frame 4. In this way, the connection between the electrical connector and the cable is completed.

[0036] When it is necessary to disconnect the electrical connector from the cable, the plastic hook plate 701 is bent and deformed, so that the limiting card plate 702 releases the plastic hook plate 701, and then the rotating frame 4 is pulled to reverse and open, so that the rotating frame 4 is separated from the sealing ring 5, and at the same time, the arc clamping plate on the rotating frame 4 is separated from the arc plate 602. When the rotating frame 4 is reversed and opened, the rotating frame 4 will drive the plastic hook plate 701 to reverse and reset synchronously. Then, a handheld screwdriver is inserted into the connecting frame 1 from top to bottom, and the screwdriver is used to pry the unlocking plate 1404 to move to the right. The second spring 1403 is stretched, so that the unlocking plate 1404 drives the strip card plate 1402 to move to the right, so that the strip card plate 1402 releases the connecting plate 1401. At this time, the first spring 1002 returns to its original state, and the first spring 1002 drives the movable frame 1001, the pressure block 11, the tool 12 and the contact piece 1 3 moves upward to reset, so that the movable frame 1001 drives the conductive sheet 3 to return to its original state, and the contact sheet 13, the cutter 12 and the pressing block 11 are all separated from the cable, so that the conductor inside the cable is disconnected from the contact sheet 13, and then the screwdriver is extended from the bottom to the top inside the connection frame 1 to separate the screwdriver from the unlocking plate 1404. At this time, the second spring 1403 returns to its original state, and the second spring 1403 drives the strip card plate 1402 and the unlocking plate 1404 to move to the left and reset. Then, the cable outside the connection frame 1 is pulled to the right, so that the end of the cable gradually passes through the inner side of the sealing ring 5 and leaves the connection frame 1. When the stripped insulation layer on the cable contacts the sealing ring 5, the stripped insulation layer on the cable is torn off manually, and then the remaining end of the cable is manually pulled out through the inner side of the sealing ring 5. In this way, the electrical connector and the cable are disconnected.

[0037] See Figure 8 and Figure 9 As shown, it also includes a fixing mechanism, which includes a movable block 15 and a tooth block 16; a movable block 15 is slidably arranged in the groove 901 of the support block 9, and arc surfaces are arranged on the left and right sides of the top of the movable block 15; tooth blocks 16 are arranged at intervals at the bottom of the movable block 15, and the tooth blocks 16 are used to fix the cable in the groove 901.

[0038] See Figure 8 and Figure 9 As shown, a pressure mechanism is also included, which includes a pressure plate 17 and a movable plate 18; a pressure plate 17 is connected to the right side of the movable frame 1001, the pressure plate 17 is located above the contact piece 13, and the bottom of the pressure plate 17 is set as an inclined surface; a movable plate 18 is slidingly set between the upper right parts of the two support plates 8 on the side close to each other, and the left and right sides of the movable plate 18 are set as inclined surfaces, and the pressure plate 17 is used to squeeze the movable plate 18 for translation when descending, and the movable plate 18 is used to squeeze the movable block 15 for movement when translation.

[0039] See Figure 8 and Figure 9As shown, it also includes a spring piece 19; two spring pieces 19 are provided between the front and rear sides of the movable block 15 and the top of the support block 9, and the spring pieces 19 are used to reset the movable block 15.

[0040] When the movable frame 1001 moves downward, the movable frame 1001 will drive the pressure plate 17 to move downward. When the inclined surface at the bottom of the pressure plate 17 contacts the inclined surface on the left side of the movable plate 18, the pressure plate 17 will squeeze the movable plate 18 to move to the right, so that the inclined surface on the right side of the movable plate 18 squeezes the arc surface on the left side of the top of the movable block 15, so that the movable plate 18 squeezes the movable block 15 and the tooth block 16 to move downward, and the spring piece 19 is deformed until the tooth block 16 presses the cable in the groove 901, thereby fixing the cable. When the movable frame 1001 moves upward to reset, the movable frame 1001 will drive the pressure plate 17 to move upward to reset. When the inclined surface at the bottom of the pressure plate 17 separates from the inclined surface on the left side of the movable plate 18, the spring piece 19 returns to its original state. The spring piece 19 drives the movable block 15 and the tooth block 16 to move upward to reset, so that the tooth block 16 loosens the cable in the groove 901, thereby releasing the cable. At the same time, the movable block 15 squeezes the movable plate 18 to move left to reset.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
