[0003] In existing technology, the structure of a flat terminal connector consists of a screw post set in a housing. The screw post is fixed in the housing by injection molding or by a slot, and the screw post has external threads. The end of the flat terminal has an opening and is fitted onto the screw post, and then a screw is screwed onto the screw post to press the flat terminal tightly.

The upper end of the support member 22 is inserted into the fifth hole 2015, and its lower end abuts against the bottom surface of the movable space 201.

[0090] In a preferred embodiment, the upper pressure plate 15 has a channel 154 for the flat terminal 500 to enter. The channel 154 is composed of two opposing L-shaped plates 151. An arc-shaped opening 152 is provided at the opposite ends of the two opposing L-shaped plates 151. The upper pressure plate 15 has a concave surface on the side facing away from the channel 154, and a pad 18 is placed in the concave surface.

[0091] In a preferred embodiment, the front handle 17 is an L-shaped structural component with an angle of less than 90 degrees, and its corner is installed on the upper opening 203 by a first pin 3.

[0092] The long plate portion of the front handle 17 has an upward-facing right-angle groove at its outer end, and the short plate portion of the front handle 17 can abut against the pad 18 and press the pad 18 down when rotated.

[0093] The upper opening 203 is further provided with a second pin at a distance from the first pin 3, and the second pin is parallel to the first pin 3.

[0094] The rear handle 16 has a T-shaped structure. Its vertical plate is installed in the slot by the third pin 31. The first end of the horizontal part of the rear handle 16 is used to fasten the right angle slot. A compression spring 6 is installed below the second end of the horizontal part. One end of the compression spring 6 abuts against the bottom surface of the slot, and the other end abuts against the lower plate surface of the second end of the horizontal part.

[0095] Example 2:

[0096] like Figure 11 As shown, the flat terminal 500 has a flat end for connection and a cylindrical end for wiring. The wiring end connects to the test wire, and the flat end is the end that inserts into the flat terminal inlet / outlet 204. The flat terminal inlet / outlet 204 has a T-shaped slot structure. The upper pressure plate 15 is made of engineering plastic. The T-shaped slot structure facilitates the insertion of the flat terminal 500 into the gap while protecting the coating on the surface of the flat terminal 500 and reducing the risk of scratching the coating.

[0097] During testing, two flat terminals 500 are typically used, and each of the two flat terminals 500 corresponds to a flat terminal current-carrying connector. For ease of testing, the flat terminal current-carrying connectors can be designed as follows: Figure 12-13 The dual-hole flat terminal connector 400 has two sets of terminal clamping mechanisms 300 sharing a single housing.

[0098] Before testing, the front handle 17 of the flat terminal current-carrying connector is in the open position (e.g., Figure 1 As shown, since the upper pressure plate 15 is not subjected to pressure from the front handle 17, the upper pressure plate 15 is lifted by the floating spring 10, and there is a gap between the upper pressure plate 15 and each probe on the terminal group. The height of this gap is sufficient for the flat end of the flat terminal 500 to enter.

[0099] During testing, the flat end of the flat terminal 500 is inserted into the gap through the flat terminal inlet / outlet 204, and the front handle 17 is pressed. Since the front handle 17 has an acute angle structure, its short plate rotates and presses down the pad 18. The pressing down of the pad 18 causes the upper pressure plate 15 to press down. Since the long probe 3014 can move up and down a certain distance through the first spring 3011 and the short probe 3022 can move up and down a certain distance through the second spring 3021, the right angle groove on the front handle 17 is prevented from descending to the locking position of the rear handle 16.

[0100] Press the front handle 17 down to its lowest point, so that the right-angled slot on the front handle 17 is engaged with the first end of the rear handle 16. Because the compression spring 6 presses against the second end of the rear handle 16, the right-angled slot on the front handle 17 is engaged. At this time, the upper pressure plate 15 locks the flat end of the flat terminal 500 in the gap. The flat end of the flat terminal 500 is in contact with the long probe 3014 and the short probe 3022. The long probe 3014 and the short probe 3022 are electrically connected to the external cable 101 through their respective connected core wires. The external cable 101 is connected to a high-voltage power supply to realize power supply.

[0101] Example 3:

[0102] like Figure 4-5 As shown, the long probe 3014 is fitted with a first spring 3011 and the short probe 3022 is fitted with a second spring 3021. This design structure ensures that each long probe 3014 and its corresponding first conductive metal adapter 3013 have good contact, and ensures that the short probe 3022 and the second conductive metal adapter 3023 have good contact. As a result, the current carrying capacity is large, the resistance is small, and the temperature rise during testing is within a reasonable range.

[0103] The terminal clamping mechanism 300 clamps the flat terminal 500 using a clamping method, eliminating the need for external tools and improving testing efficiency.

[0104] Example 4:

[0105] Each core wire passes through the waterproof connector 2 and is then crimped together by the terminal block 102. The terminal block 102 is a BN70 terminal block. The external cable 101 is a high-voltage cable. Since the two long probes 3014 and the two short probes 3022 are electrically connected to the external cable 101, the flat terminal 500 can connect to the high-voltage power supply when it contacts any probe. Therefore, the power cable 100 structure of the present invention has reliable and stable current transmission, which improves the safety of the test.

[0106] Example 5:

[0107] like Figure 12-13 As shown, Figure 12This is an assembly diagram of another flat terminal current-carrying connector of the present invention. Figure 13 for Figure 12 Exploded view.

[0108] The flat terminal current-carrying connector of the present invention is not limited to a single flat terminal inlet / outlet structure 204; the flat terminal current-carrying connector of the present invention can be designed with multiple flat terminal inlet / outlet structures 204. Figure 12 It is a dual-hole flat terminal current-carrying connector with two flat terminal inlets / outlets 204. This dual-hole flat terminal current-carrying connector shares a common housing. Figure 12 It can be viewed as a structure in which the sides of the two flat terminal current-carrying connectors in Embodiment 1 are glued and fixed together.

[0109] Example 6:

[0110] like Figure 9 As shown, Figure 9 This is a diagram of the clamping structure at the tip of the long or short probe of the present invention. The clamping surface 303 of the long probe 3014 or the short probe 3022 is a non-planar structure. The clamping surface 303 is arrayed with pyramid-shaped structural columns. The outer end of the pyramid-shaped structural column is a narrow end, which is rectangular, and the bottom end of the pyramid-shaped structural column is a wide end, which is rectangular.

[0111] The clamping surface is designed as a pyramid-shaped column structure, which can improve the clamping force between the clamping surface 303 and the flat terminal without affecting the current flow.

[0112] Example 7: The back cover 12, front shell 14, upper pressure plate 15, and lower pressure plate 20 are made of engineering plastics, which are lighter than other metal products. The surfaces of the back cover 12 and front shell 14 are roughened, providing a good feel and experience during testing.

[0113] In summary, the flat terminal current-carrying connector of the present invention is easy to operate: the flat terminal current-carrying connector of the present invention is used for quick connection of flat terminals. The flat terminal is inserted into the gap, and then the front handle is pressed down to make the upper pressure plate and terminal group clamp the flat terminal. The front handle can be locked by the rear handle. The connection and unlocking of the flat terminal can be completed with one hand, which reduces the labor intensity of the user and improves the testing efficiency.

[0114] The present invention increases the service life of the flat terminal current-carrying connector: through the design of spring, upper pressure plate, lower pressure plate and floating spring, the number of uses of the flat terminal current-carrying connector is greatly increased, thereby increasing the service life of the flat terminal current-carrying connector and meeting the testing needs of more users.

[0115] The flat terminal current-carrying connector of this invention is easy to maintain: the front shell 14 and the rear cover 12 are detachable structures, facilitating maintenance.

[0116] The invention provides a flat terminal current-carrying connector with reliable and stable current transmission: each terminal on the terminal group is connected to a core wire, and all core wires are connected to an external cable. The external cable is a high-voltage cable, ensuring reliable and stable current transmission. The connection between multiple terminals on the terminal group and the flat terminal improves the reliability and stability of current transmission.

[0117] The flat terminal current-carrying connector of the present invention improves the current carrying capacity: the four sets of probes of the flat terminal current-carrying connector of the present invention can float independently, the contact surface between the probes and the flat terminals is large, thereby improving the clamping force and further increasing the current carrying capacity, while the temperature rise is within a reasonable range.

[0118] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
