Description

Technical Field

[0001] This utility model relates to the field of electrical connector testing technology, and in particular to a rapid inspection terminal pin removal device. Background Technology

[0002] During the production of wires, there may be instances where terminals are not properly inserted or are loosely connected, which may lead to poor contact, resulting in electrical connection interruptions or instability, affecting the normal use of electronic equipment. Short circuits or overloads caused by improperly inserted terminals may also damage equipment or cause safety accidents. In order to ensure the reliability and safety of electrical connections and avoid electrical faults caused by poor terminal insertion, it is necessary to perform terminal pin removal tests on the finished wire products to ensure the safety and stability of the equipment.

[0003] In the existing terminal pin removal inspection operation, the operator usually pulls the single wire with the terminal inserted and manually judges whether the terminal of the wire is inserted in the middle. The manual inspection is time-consuming and labor-intensive, with high labor costs. In addition, manual inspection is prone to misjudgment, which may lead to the failure to detect defective products. The efficiency and automation of terminal pin removal inspection are too low, the labor intensity is high, and it affects the production efficiency and quality of products. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device for quickly inspecting the terminal pin removal status. By pressing the finished wire with the inserted terminal facing down onto a push-to-retract switch, the relay and power module are connected. At the same time, the telescopic probe pushes out any loosely inserted terminals. The pressed telescopic probe connects the relay and the indicator light. The indicator light illuminates to show that the terminal is properly inserted. If there are loosely inserted terminals that are pushed out, the alarm will light up and sound an alarm. This effectively improves the efficiency of inspecting the terminal insertion status at the wire end and reduces the intensity of manual operation.

[0005] This utility model is achieved through the following technical solution: A rapid terminal pin removal device includes a housing, a power switch, and a power module. The power switch is connected to a corner of the top surface of the housing, and the power module is connected to the bottom surface inside the housing. The power switch is connected to the power module and a power source via wires. A relay is connected to the bottom surface inside the housing next to the power module. A push-to-retract switch is connected to the center of the top surface of the housing. A telescopic probe is connected to the top surface of the housing inside the push-to-retract switch. An alarm and an indicator light are connected sequentially to the top surface of the housing next to the push-to-retract switch.

[0006] Furthermore, the top surface of the press-to-retract switch is connected to a groove that conforms to the shape of the wire end.

[0007] Furthermore, the pins of the push-to-retract switch are connected to the power module and the relay respectively via wires.

[0008] Furthermore, the number of telescopic probes and indicator lights is the same as the number of terminals connected to the end of the wire.

[0009] Furthermore, the telescopic probes are vertically and equidistantly connected to the center of the top surface of the housing inside the push-to-open telescopic switch. The position of the telescopic probes inside the push-to-open telescopic switch is the same as the position of the terminals on the wire end.

[0010] Furthermore, the main body of the telescopic probe is connected to a relay via wires.

[0011] Furthermore, the indicator light and its corresponding telescopic probe are connected to the same relay via wires.

[0012] Furthermore, the alarm is an alarm buzzer, and the pins at both ends of the alarm are connected to the relay via wires.

[0013] Compared with the prior art, this utility model has the following obvious advantages: I. This utility model features a groove on the top surface of a push-to-open telescopic switch, shaped to fit the end of a wire. Telescopic probes are vertically and equidistantly arranged on the top surface of the inner housing of the push-to-open telescopic switch. The number and position of the telescopic probes inside the push-to-open telescopic switch are the same as the number and position of the terminals on the end of the wire. When inspecting the connection status of the terminals at the end of the wire, the wire end is aligned with the groove on the top of the push-to-open telescopic switch and pressed down. The telescopic probes press against each terminal, and unstable terminals are pushed out, making the terminal connection status more obvious. This allows for the inspection of the connection status of all terminals at once, improving inspection efficiency and reducing manual operation.

[0014] II. In this utility model, the main body of the telescopic probe is connected to the relay via a wire, and the indicator light corresponding to the telescopic probe is also connected to the same relay via a wire. When inspecting the terminal insertion status at the end of the wire, the telescopic probe pressed to the bottom will be sensed by the device, and the indicator light will light up when the power is turned on, indicating that the corresponding terminal insertion status is stable. If the indicator light does not light up, the telescopic probe corresponding to it has not been pressed to the bottom, that is, the terminal pressed by the telescopic probe is not inserted properly, thus making the inspection of the terminal insertion status more accurate.

[0015] Third, this utility model has an alarm connected to the top surface of the housing next to the push-to-open switch. The two pins of the alarm are connected to the relay through wires. When the push-to-open probe is not pushed down to the bottom, the alarm lights up red and sounds an alarm. When the push-to-open probe is fully pushed down, the alarm displays a green light, indicating that all terminals are properly connected. This can more clearly remind the operator and prevent the operator from misinterpreting the test results. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a rapid terminal pin removal device, including a housing 1, a power switch 2, a push-to-retract switch 3, a telescopic probe 4, an indicator light 5, an alarm 6, a power supply 7, and a relay 8. In this embodiment, the power switch 2 is connected to a corner of the top surface of the housing 1, the power module 7 is connected to the bottom surface inside the housing 1, the power switch 2 is connected to the power module 7 and the power supply via wires, the relay 8 is connected to the bottom surface inside the housing 1 next to the power module 7, the push-to-retract switch 3 is connected to the center of the top surface of the housing 1, the top surface of the push-to-retract switch 3 has a groove adapted to the shape of the wire end, and the pins of the push-to-retract switch 3 are connected to the power module 7 and the relay 8 via wires respectively.

[0020] Telescopic probes 4 are vertically and equidistantly connected to the center of the top surface of the housing 1 inside the push-to-retract switch 3. The position of the telescopic probes 4 inside the push-to-retract switch 3 is the same as the position of the terminals on the wire end. Alarm 6 and indicator lights 5 are sequentially connected to the top surface of the housing 1 next to the push-to-retract switch 3. The number of telescopic probes 4 and indicator lights 5 is the same as the number of terminals connected to the wire end. The main body of the indicator light 5 and the corresponding telescopic probe 4 are connected to the same relay 8 through wires. Alarm 6 is an alarm buzzer. The pins at both ends of alarm 6 are connected to relay 8 through wires.

[0021] The working principle of this utility model is as follows: When using this utility model, the operator connects the device to the power supply, turns on the power switch 2 to power the power module 7, and inserts the finished wire with the terminal connected, with the end face down, into the groove connected to the top surface of the push-pull switch 3 and presses it down. After the push-pull switch 3 is pressed down, the power module 7 and the relay 8 are connected. At the same time, the telescopic probe 4 presses against the corresponding terminal. Terminals that are not properly connected will be pushed out by the telescopic probe 4. The telescopic probe 4 that is not pressed to the bottom will not be detected by the device, and the indicator light 5 connected to the same relay 8 will not light up. At the same time, the alarm 6 lights up red and sounds an alarm to remind the operator. After the operator removes the finished wire, reconnects the terminal corresponding to the unlit indicator light 5 and retests.

[0022] If all terminals are plugged in, when the telescopic switch 3 is pressed down at the end of the finished wire, all telescopic probes 4 will be pressed down to the bottom and sensed by the device. The indicator lights 5 connected to the same relay 8 will all light up, and the alarm 6 will light up green, indicating that all terminals plugged into the end of the wire are plugged in. The operator can then remove the finished wire.
