DETAILED DESCRIPTION

[0031] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] like Figures 1 to 3As shown, the magnetic attraction connector provided in this embodiment includes one or more connection units. Each connection unit includes an insulating shell 12; a first input port 7 and a first output port 8 are arranged on the top of the insulating shell 12.

[0034] A coding mark area 1 is provided between the first input port 7 and the first output port 8, and the coding mark area 1 is used to encode the port as needed. For example, if there are five connection units, the five connection units can be digitally encoded, such as code 1, code 2, code 3, code 4 and code 5 and so on.

[0035] Magnetic objects 13 (eg, magnets or lodestones) are embedded in the front and back sides of the insulating shell 12. The magnetic objects 13 adsorb the connection units together in the order of port coding. For example, five digitally coded connection units are adsorbed together in ascending order of numbers.

[0036] It should be noted that the connection units may also be arranged in a certain order according to actual needs, or the arranged connection units may be adjusted.

[0037] A copper square flow insert 11 is embedded in the insulating shell 12 , and circular holes with the same inner cavity diameter as the copper square flow insert 11 are arranged on the left and right sides of the insulating shell 12 .

[0038] It should be noted that the copper flow-through square insert 11 has a square shape and a circular inner cavity. There are two threaded holes on the copper flow-through square insert 11, so that the first spinning screw 4 and the second spinning screw 2 enter the inner cavity of the copper flow-through square insert 11 through the two threaded holes. The copper flow-through square insert 11 is a prior art for those skilled in the art and will not be described in detail here.

[0039] A first spinning screw 4 with a first flat washer 5 is provided on the top of the insulating housing 12 . The first spinning screw 4 is screwed to the insulating housing 12 in a threaded manner and enters the inner cavity of the copper flow-through square insert 11 through a threaded hole on the copper flow-through square insert 11 .

[0040] A second spinning screw 2 with a second flat washer 6 is also provided on the top of the insulating shell 12 . The second spinning screw 2 is screwed to the insulating shell 12 by threading and enters the inner cavity of the copper flow-through square insert 11 through the threaded hole on the copper flow-through square insert 11 .

[0041] The first input port 7 is formed by a first screw 4 with a first flat washer 5 disposed on the upper portion of the insulating housing 12. Figure 4 As shown, when in use, the first flat washer 5 presses the switch device connection wire and the switch device connection wire is tightened by screwing the first screwing screw 4.

[0042] The first output port is formed by a second screw 2 with a second flat washer 6 disposed on the upper portion of the insulating housing 12. Figure 4 As shown, when in use, the test line of the test equipment is crimped by the second flat pad 6 and the test line of the test equipment is compressed by screwing the second screwing screw 2, thereby testing the switch device through the first input port and the first output port 8.

[0043] Among them, the screw and flat washer spinning structure has good versatility and can be used with conventional plum screwdrivers and flat-blade screwdriver tools. The screw form is not fixed. For thicker stranded wires, conventional screws can be selected for vertical compression, or they can be optimized for ball-head spinning screws for weak currents. The spherical compression effect is more reliable.

[0044] Protective platforms 3 are also provided on the edges of the insulating housing 12 at both sides of the first flat pad 5 crimping area of ​​the first input port 7 and the second flat pad 6 crimping area of ​​the first output port 8 to avoid short circuit between cables.

[0045] like Figure 5 As shown, the switch device connecting wire is inserted into the copper flow-through square insert 11 through the round hole near the first spinning screw 4. By screwing the first spinning screw 4, the switch device connecting wire is pressed tightly against the inner cavity of the copper flow-through square insert 11 by the first spinning screw 4 to form a second input port.

[0046] The test line of the test equipment is extended into the copper flow-through square insert through the round hole close to the second spinning screw. By screwing the second spinning screw, the test line of the test equipment is pressed against the inner cavity of the copper flow-through square insert by the second spinning screw to form a second output port, thereby realizing the test of the switch device through the second input port and the second output port.

[0047] It should be noted that the input port and the output dual port are optional and can be combined to select the ports; for example, the combination of the first input port and the second output port, or the combination of the second input port and the first output port can be selected.

[0048] In addition, the first input port and the first output port are suitable for single wire and hard wire, and the second input port and the second output port are suitable for twisted wire and soft wire.

[0049] Magnetic objects such as magnets are embedded on both sides of the insulating shell of the connection unit of the connector of the utility model. The magnetic attraction design of the connector unit can be conveniently arranged in a coded sequence according to actual needs. The connection unit combination can be applied to multi-channel test conditions, and the test lines are easy to sort out and check, which helps to improve safety and work efficiency. The connector has a coding marking function, and the test equipment can use the coding marking function to pre-connect the test line of the test equipment in advance, and then adjust the coding corresponding to the switch device connection line according to actual needs. This helps to effectively protect the test equipment, avoid repeated plugging and unplugging, and increase the service life of the test equipment.

[0050] Although the utility model is described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the utility model is not limited thereto. Without departing from the spirit and essence of the utility model, ordinary technicians in the field can make various equivalent modifications or substitutions to the embodiments of the utility model, and these modifications or substitutions should be within the scope of the utility model / any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
