Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for the tensile property of a connector. Background Technique

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. A device that connects two active devices, transmits current or signals, and after the male end and the female end are in contact, they can transmit information or current, is also called a connector. The connector includes a plastic core and terminals. The terminals are arranged on the plastic core, and the terminals are connected and conducted with an external device through wires.

[0003] Most connectors are assembled and used on various equipment and devices. During the installation process, use process, transportation process, and maintenance process, the wires connected to the connector terminals will be pulled, so that the terminals are stressed. If the terminals are displaced due to the stress, the connector cannot be used continuously. Therefore, after the connector terminals are connected to the wires, they will all undergo a tensile property test. However, most of the existing devices for detecting the tensile property of connectors have complex structures and high production costs. Therefore, it is necessary to improve the existing detection devices for the tensile property of connectors. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a detection device for the tensile property of a connector, which can effectively solve the problems of complex structure and high production cost of the existing detection device for the tensile property of a connector.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A detection device for the tensile property of a connector includes a base, a detection seat, a control module, and a buzzer; the detection seat is arranged on the base, the detection seat is provided with a cavity with an upward opening, the front inner wall surface of the cavity is provided with a plurality of detection terminals connected to the connector terminals, the rear end of the cavity is provided with a slot for the wire to extend out, and the slot communicates with the cavity; the control module is arranged on the base and is connected to the aforementioned plurality of detection terminals; the buzzer is arranged on the base and is connected to the control module.

[0007] As a preferred scheme, it further includes a slope, the slope has a slope surface, and the detection seat is installed on the slope surface. The design of installing the detection seat on the slope surface is more in line with ergonomics, making the operation of the staff more convenient.

[0008] As a preferred scheme, the detection seat is elastically installed on the slope through an elastic member, and the elastic installation can provide a buffering effect to prevent the wire from being disconnected from the connector terminals due to the large pulling force on the wire by the staff at the beginning.

[0009] As a preferred solution, the elastic member is a spring.

[0010] As a preferred solution, a through slot extending forward and backward is opened at the front end of the detection seat, and a limit piece that can move forward and backward is arranged in the through slot. After the limit piece moves backward to the right position, the limit piece extends backward and is located above the cavity to ensure that the connector will not be forced out of the cavity.

[0011] As a preferred solution, a switch is further included, and the switch is connected to the control module.

[0012] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0013] A cavity is provided on the detection seat, a slot for the wire to extend out is provided at the rear end of the cavity, and a plurality of detection terminals connected to the connector terminals are provided on the inner wall surface of the front end of the cavity. When the staff pulls the wire, the terminal moves backward without contacting and conducting with the detection terminal, and the buzzer sounds an alarm. After the staff releases the wire, if the terminal is reset, the buzzer stops sounding the alarm. If the terminal is not reset, the connector fails, and the buzzer continues to sound the alarm. In addition, the design of the base, the detection seat, the control module and the buzzer is relatively simple and easy to assemble, thereby reducing the production cost of the detection device.

[0025] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, including a base 10, a detection base 20, a control module (not shown) and a buzzer 30.

[0026] The detection seat 20 is arranged on the base 10, and the detection seat 20 is provided with a cavity 21 opening upward, and the inner wall surface of the front end of the cavity 21 is provided with a plurality of detection terminals 22 connected to the connector terminals, and the rear end of the cavity 21 is provided with a slot 23 for the wire to extend out, and the slot 23 is connected to the cavity 21; in this embodiment, the front end of the detection seat 20 is provided with a through slot 24 extending forward and backward, and a limit member 25 that can move forward and backward is arranged in the through slot 24. After the limit member 25 moves backward to the right position, the limit member 25 extends backward and is located above the cavity 21, ensuring that the connector will not be forced to detach from the cavity 21.

[0027] The control module is disposed on the base 10 , and is connected to the aforementioned plurality of detection terminals 22 .

[0028] The buzzer 30 is disposed on the base 10 and connected to the control module.

[0029] And, further comprising a slope 40 and a switch 50, the slope 40 having a slope surface 41, the detection seat 20 is mounted on the slope surface 41, the design of the detection seat 20 being mounted on the slope surface 41 is more in line with human mechanics, making the operation of the staff more convenient; the switch 50 is connected to the control module; in this embodiment, the detection seat 20 is elastically mounted with the slope 40 through an elastic member 60, and the elastic mounting can provide a buffering effect to prevent the staff from applying a large pulling force to the wire at the beginning, resulting in the wire being disconnected from the connector terminal, specifically, the elastic member 60 is a spring;

[0030] The method of using this embodiment is described in detail as follows:

[0031] First, place the connector into the cavity 21, the connector terminal is in contact with the detection terminal 22, and the wire connected to the connector terminal extends outward from the slot 23. Then, push the limit member 25 backward so that the limit member 25 is located above the cavity 21 and presses the connector. Then, the detection device is connected to the external power supply, and the switch is turned on. Finally, the staff pulls the wire once. When pulling the wire, the terminal moves backward without contacting and conducting with the detection terminal 22, and the buzzer 30 sounds an alarm. After the staff releases the wire, if the terminal is reset, the buzzer 30 stops sounding the alarm, and the connector's anti-pull performance is qualified. If the terminal is not reset, the buzzer 30 continues to sound the alarm, and the connector's anti-pull performance is unqualified.

When the staff pulls the wire, the terminal moves backward without contacting and conducting with the detection terminal, and the buzzer emits an alarm sound. After the staff releases the wire, if the terminal resets, the buzzer stops emitting the alarm sound; if the terminal does not reset, the connector fails and the buzzer continues to emit the alarm sound. In addition, the designs of the base, the detection base, the control module, and the buzzer are relatively simple and convenient for assembly, thereby reducing the production cost of the detection device.

[0033] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
