Description

At this time, they can be connected with terminals and can be disconnected at any time without welding or wrapping them together. It is very convenient and fast. In order to ensure reliable contact, a certain crimping area is required so that it can carry enough current. When the terminal block is produced, it is necessary to perform integrity detection on the terminal block. For example, patent number CN114487921A discloses a terminal block voltage detection device and a terminal block fault detection method. When it is necessary to measure the secondary circuit terminal block, the voltage of different wires on the terminal block can be measured quickly and conveniently, and the spacing between adjacent first measuring pieces can be adjusted to adapt to terminals with different spacings, solving the problem that the voltage measurement of the terminal block is relatively cumbersome in the prior art.

DETAILED DESCRIPTION

[0027] In order to make the technical solutions in the embodiments of the present invention clearly and completely described, and the features and advantages can be more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0028] Example 1

[0029] See also Figures 1 to 4The present invention provides a connection device for detecting a wiring terminal, comprising a wiring terminal 101 and a cover 102, wherein the cover 102 is detachably connected to the wiring terminal 101, and further comprising an input line 103, an output line 104, a slot 105, a copper column 106, a detection terminal 107, a latch 108, a disconnection component 109, a detection component 110 and a protective cover 111, wherein the input line 103 and the output line 104 are arranged in the wiring terminal 101, the copper column 106 is connected between the input line 103 and the output line 104, the slot 105 is arranged above the copper column 106 on the wiring terminal 101, a limiting groove 105a is arranged on the side of the slot 105, the latch 108 is connected below the detection terminal 107, and the detection terminal 10 7 is connected to the wiring terminal 101 through the plug 108 and the slot 105. A limit block 108a is set on the side of the plug 108. Two limit blocks 108a are set and located in different directions. The limit block 108a cooperates with the slot 105 to effectively prevent the limit block 108a from being inserted into the slot 105. The disconnection component 109 is set at the lower end of the copper column 106. After the plug 108 is inserted into the slot 105, it cooperates with the copper column 106 to disconnect the input line 103 and the output line 104. The detection component 110 is set on the detection terminal 107. After the output line 104 and the input line 103 are disconnected, it is connected to the output line 104 and the input line 103 for detection. The protective cover 111 is set at the upper end of the detection terminal 107.

[0030] Working principle: When conducting the inspection, the operator holds the inspection terminal 107, and inserts the pin 108 into the slot 105 when the limit block 108a is aligned with the limit groove 105a. By arranging the limit block 108a and the limit groove 105a in different directions, it is possible to effectively prevent the pin 108 from being inserted into the slot 105 by mistake. Since the pin 108 is longer than the inspection column 110c, it can be ensured that the lower end of the pin 108 has been against the upper end of the copper column 106 before the bottom end of the inspection column 110c contacts the inner wall of the inspection groove 110b. At this time, since the pin 108 squeezes the disconnect block 109b and the disconnect spring 109c, the copper column 106 is disconnected from the input line 103 and the output line 104. The pin 108 is an insulator, so the circuit is not energized and is in a disconnected state. When the pin 108 is inserted into the bottom, the inspection column 110c also enters the inspection groove 110b and is connected to the inspection circuit 110a.

[0031] After the inspection is completed, the operator pulls out the inspection terminal 107 and inserts the cover 102 into the terminal block 101. Before inserting the cover 102 into the terminal block 101, first align the limit rod 102c on the connecting rod 102b with the limit groove 105a, and then insert the connecting rod 102b into the slot 105. Similarly, by setting the limit rod 102c and the limit groove 105a in different directions, it is possible to effectively prevent the connecting rod 102b from being inserted into the slot 105 due to the wrong insertion. After the bottom of the cover 102 and the outer wall of the terminal block 101 are matched, tighten the bolt 102a to prevent the cover 102 from falling off.

[0032] Specifically, the cover 102 is provided with a bolt 102a, and the cover 102 is connected to the terminal 101 through the bolt 102a. The bolt 102a cooperates with the cover 102. The bolt 102a is embedded in the inner wall of the cover 102 and is non-detachably connected to the cover 102 to prevent the bolt 102a from falling off. A connecting rod 102b is provided at the lower end of the cover 102, and a limiting rod 102c is provided on the connecting rod 102b. The limiting rod 102c cooperates with the limiting groove 105a. Both the limiting rod 102c and the limiting groove 105a are provided with two and are arranged in different directions, which can effectively prevent wrong insertion during the detection process. The disconnect component 109 includes a disconnect groove 109a, a disconnect block 109b and a disconnect spring 109c. The disconnect groove 109a is opened at the lower end of the copper column 106 in the terminal 101, and the disconnect block 109b is slidably connected in the disconnect groove 109a. The disconnect block 109b abuts against the lower end of the copper column 106, and the two ends of the disconnect spring 109c are respectively connected to the inner wall of the terminal 101 at the lower end of the disconnect block 109b. The upper end of the copper column 106 cooperates with the lower end of the plug 108. During the detection process, the lower end of the plug 108 abuts against the upper end of the copper column 106 and squeezes the disconnect block 109b downward and then squeezes the disconnect spring 109c. At this time, the copper column 106 is disconnected from the input line 103 and the output line 104. Since the plug 108 is made of insulating material, the circuit is now non-conductive. The detection component 110 includes a detection circuit 110a, a detection slot 110b and a detection column 110c. The detection slot 110b is opened on the wiring terminal 101. Each input circuit 103 and output circuit 104 is provided with a detection slot 110b. The detection circuit 110a is provided in the detection slot 110b. The detection circuit 110a is connected to the corresponding input circuit 103 or output circuit 104 below the detection slot 110b. The detection column 110c is set in the detection terminal 107. The length of the detection column 110c is less than the length of the pin 108. In the process of inserting the detection column 110c into the detection slot 110b, the pin 108 is inserted into the slot 105 first. At this time, the lower end of the pin 108 abuts against the upper end of the copper column 106 and squeezes the disconnection spring 109c downward to disconnect the circuit. The detection column 110c cooperates with the detection circuit 110a. A connection groove 107 a is provided above the detection column 110 c in the detection terminal 107 , and a protection cover 111 is disposed on the connection groove 107 a .

[0033] Example 2

[0034] See also Figures 4 to 8, a connection device for detecting a wiring terminal is provided, and a protection component can also be arranged in the detection terminal 107, the protection component includes a switch 107b-1, a lower pressing groove 107b-2, a lower pressing block 107b-3 and a connecting component 107b-4, the lower pressing groove 107b-2 is opened in the detection terminal 107, the lower pressing block 107b-3 is slidably connected in the lower pressing groove 107b-2, the lower end of the lower pressing block 107b-3 is fixedly connected to the pin 108, the switch 107b-1 is slidably connected to the side wall of the detection terminal 107, and the connecting component 107b-4 is arranged in the connecting groove 107a. A downward pressing chamfer 107b-1a is provided on the side of the switch 107b-1 close to the detection terminal 107, and the downward pressing chamfer 107b-1a cooperates with the downward pressing block 107b-3. When the switch 107b-1 moves into the downward pressing groove 107b-2, the downward pressing chamfer 107b-1a squeezes the downward pressing block 107b-3. At this time, the downward pressing block 107b-3 moves downward under the squeezing of the downward pressing chamfer 107b-1a. The connecting component 107b-4 includes an upper connecting column 107b-4a, a connecting baffle 107b-4b, a lower connecting column 107b-4c and a connecting spring 107b-4d. The connecting baffle 107b-4b is slidably connected in the connecting groove 107a. The lower connecting column 107b-4c is fixed to the lower end of the connecting baffle 107b-4b. The two ends of the connecting spring 107b-4d are respectively abutted against the lower end of the connecting baffle 107b-4b and the inner wall of the detection terminal 107. The upper end of the connecting baffle 107b-4b is matched with the lower end of the lower pressing block 107b-3. The upper end of the connecting baffle 107b-4b is always in contact with the lower end of the lower pressing block 107b-3, the lower end of the lower connecting column 107b-4c is matched with the upper end of the detection column 110c, and the circuit is connected when the lower end of the lower connecting column 107b-4c contacts the upper end of the detection column 110c. The upper connecting column 107b-4a is arranged at the upper end of the connecting baffle 107b-4b, and the upper connecting column 107b-4a is slidably connected to the center of the protective cover 111, so that the detection contact can extend into the protective cover 111 and connect with the upper connecting column 107b-4a during detection. A pull rod 107b-1b is arranged on the side of the switch 107b-1 away from the detection terminal 107.

[0035] The rest of the structure is the same as that of Example 1.

[0036] Working principle: When the plug 108 is inserted into the slot 105 and abuts against the upper end of the copper column 106 and presses down the disconnect spring 109c, the circuit is disconnected. At this time, the detection column 110c cooperates with the detection circuit 110a. Since the detection column 110c and the connecting column do not touch each other under normal conditions, it can prevent the operator's hand from flowing into the connection terminal 101 along the detection column 110c when there is water on the palm of the operator's hand, and it can also prevent the operator's hand from indirectly contacting the connection terminal 101 through the detection terminal 107. During detection, the operator pushes the pull rod 107b-1b on the switch 107b-1 to move into the downward pressing groove 107b-2. A downward pressing chamfer 107b-1a is provided on the side of the switch 107b-1 close to the detection terminal 107. The downward pressing chamfer 107b-1a cooperates with the downward pressing block 107b-3. As the switch 107b-1 moves, the downward pressing chamfer 107b-1a will squeeze the downward pressing block 107b-3. At this time, the downward pressing block 107b-3 moves downward under the squeezing of the downward pressing chamfer 107b-1a. Since the lower end of the lower pressing block 107b-3 cooperates with the upper end of the connecting baffle 107b-4b, the upper end of the connecting baffle 107b-4b is always in contact with the lower end of the lower pressing block 107b-3 and a connecting spring 107b-4d is provided on the outer wall below the connecting baffle 107b-4b, and the two ends of the connecting spring 107b-4d are respectively in contact with the lower end of the connecting baffle 107b-4b and the inner wall of the detection terminal 107. Therefore, when the lower pressing block 107b-3 moves downward, it will squeeze the connecting baffle 107b-4b, and the connecting baffle 107b-4b also moves downward and squeezes the connecting spring 107b-4d until the lower end of the lower connecting column 107b-4c contacts the upper end of the detection column 110c. At this time, the detection terminal 107 is connected to the wiring terminal 101, and the operator can extend the detection contact into the protective cover 111 for detection. The upper connecting column 107b-4a is arranged at the upper end of the connecting baffle 107b-4b, and the upper connecting column 107b-4a is slidably connected to the center of the protective cover 111, which can ensure that the detection contact extends into the protective cover 111 and connects with the upper connecting column 107b-4a.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
