Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric connector detection, and particularly relates to a plug pin in-place detection device. BACKGROUND

[0002] In the electrical connection of a locomotive signal receiving coil, an electric connector (aviation plug socket) is mostly used at present. The connection quality of the electric connector is crucial, and the installation in place of a crimping type plug connector (plug pin and socket) needs to be detected for each product.

[0003] The existing detection scheme of the connector manufacturer is as follows: when the plug pin is installed in place, the anti-back piece is popped up and clamped on the step in the installation hole. During detection, a detection pin is opposite to the measured plug connector, and the plug connector is pushed in the opposite direction of the installation direction with a certain force, and then whether the plug connector is backed up is observed by naked eyes. If the plug connector is backed up, it is judged that the anti-back piece is not clamped, that is, the installation is not in place.

[0004] The existing junction box product is provided with six three-core sockets of the same type on each. When this detection operation is performed, 18 times of repeated operations are needed. Each time, the detection pin and the measured plug connector need to be accurately aligned, which makes the labor intensity very large. Moreover, the misjudgment is prone to occur by the naked eye observation. CONTENT OF THE INVENTION

For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0037] The preferred embodiments of the utility model are described below in combination with the drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0038] As Figure 1 The electric connector comprises a pin 9 and a socket 10, the pin 9 is mounted in the mounting groove of the socket 10, an elastic sheet 101 is mounted in the mounting groove, the elastic sheet 101 is used for limiting and fixing the first protrusion 91 on the pin 9 mounted in place, and the side of the first protrusion 91 on the pin 9 towards the plug-in end is provided with an inclined surface, so that the installation of the pin 9 is facilitated.

[0039] In combination with the Figures 2-6 As shown in the figure, the embodiment of the present application provides a pin-to-position detection device, which comprises:

[0040] A detector body 1 is provided with a plurality of detection grooves, and the detection grooves are used for accommodating the to-be-detected objects;

[0041] A detection assembly 2 is arranged in each detection groove, and the detection assembly 2 is used for detecting whether the to-be-detected object is plugged in place.

[0042] The pin-to-position detection device provided by the embodiment comprises a detector body 1 and a detection assembly 2, and the plurality of detection grooves provided on the detector body 1 provide a plug-in detection space for the to-be-detected objects. The size of the detection groove is matched with the to-be-detected object, i.e. the pin 9, so that the pin 9 can be stably placed in the detection groove, the shaking or displacement of the pin 9 in the detection process is reduced, and the detection accuracy is improved. Each detection groove is provided with the detection assembly 2, so that each to-be-detected object can be independently and accurately detected. When the pin 9 is plugged in place, the detection assembly 2 can timely notify the operator of the detection result.

[0043] In use, the to-be-detected object is placed in the detection groove of the detector body 1, and the detection assembly 2 detects whether the pin 9 is plugged in place, when the pin 9 is plugged in place on the socket 10, the detection assembly 2 sends a signal, indicating that the pin 9 is plugged in place. If the pin 9 is not plugged in place, the detection assembly 2 does not send a signal, reminding the operator to adjust or further check.

[0044] The detection assembly 2 comprises:

[0045] a measuring needle 21 arranged in the detection groove;

[0046] a resilient member 22 arranged between the measuring needle 21 and the detection groove.

[0047] In the technical scheme, the measuring needle 21 is arranged in the detection groove, and can accurately contact the pin 9 and perceive the position state thereof. The position information of the pin 9 can be accurately transmitted during detection. The resilient member 22 is arranged between the measuring needle 21 and the detection groove. The resilient member 22 can be a spring, elastic rubber or other elastic material. During detection, when the object to be detected is inserted into the detection groove, the resilient member 22 is compressed to generate a certain elastic force. The elastic force can ensure that the measuring needle 21 and the pin 9 maintain good contact, thereby improving the detection accuracy. After detection is completed, the resilient member 22 can push the measuring needle 21 to reset, so that the detection device is ready for the next detection.

[0048] In use, when the object to be detected is inserted into the detection groove, the pin 9 first contacts the measuring needle 21. As the pin 9 continues to be inserted, the resilient member 22 is gradually compressed. When the pin 9 is inserted in place, the elastic sheet 101 on the socket 10 can limit and fix the first protrusion 91 on the pin 9. At this time, the pin 9 still maintains a stable positional relationship with the socket 10 under the action of the elastic force of the resilient member 22. If the pin 9 is not inserted in place, the elastic sheet 101 on the socket 10 cannot limit and fix the first protrusion 91. At this time, the pin 9 will be separated from the socket 10 outward under the action of the elastic force of the resilient member 22, thereby achieving detection of whether the pin 9 is inserted in place.

[0049] The detection groove comprises an insertion groove and a limiting groove;

[0050] The detector body 1 comprises a housing 11, a first mounting plate 12 and a second mounting plate 13. The first mounting plate 12 and the second mounting plate 13 are arranged in the housing 11. The first mounting plate 12 is provided with an insertion groove. The second mounting plate 13 is provided with a limiting groove. The diameter of the limiting groove is greater than that of the insertion groove.

[0051] The measuring needle 21 comprises a contact section 211, a limiting section 212 and a triggering section 213 connected in sequence. The contact section 211 is arranged in the insertion groove. The limiting section 212 and the triggering section 213 are arranged in the limiting groove. The diameter of the limiting section 212 is greater than that of the insertion groove. The resilient member 22 is arranged between the limiting section 212 and the limiting groove, and is sleeved on the outside of the triggering section 213.

[0052] In this technical solution, the housing 11 of the detector body 1 protects the internal structure and provides installation space for the first mounting plate 12 and the second mounting plate 13. The insertion slots in the first mounting plate 12 and the limiting slots in the second mounting plate 13 cooperate with each other to form a complete detection channel.

[0053] The contact section 211 of the stylus 21 is positioned within the insertion slot. Its dimensions match the slot, allowing it to accurately contact the object being tested and sense changes in the position of the pin 9. When the pin 9 is inserted, the contact section 211 responds quickly, transmitting the position information of the pin 9 to the subsequent limit section 212 and trigger section 213.

[0054] The limiting section 212 and trigger section 213 are positioned within the limiting slot. The diameter of the limiting section 212 is larger than that of the insertion slot, ensuring the stability of the stylus 21 during testing. An elastic member 22 is positioned between the limiting section 212 and the limiting slot and sleeved around the trigger section 213, providing a stable spring force to the stylus 21 during insertion and removal of the pin 9. When the pin 9 is inserted, the elastic member 22 is compressed, generating a spring force that maintains close contact between the stylus 21 and the pin 9, ensuring accurate testing. Furthermore, after the pin 9 is removed, the elastic member 22 quickly resets the stylus 21, preparing for the next test.

[0055] Also includes:

[0056] A circuit board 3 is provided in the housing 11 and is located on one side of the second mounting plate 13. Switches 4 are provided on the circuit board 3 at locations matching the detection slots.

[0057] A light-emitting tube 5 is provided on the detector body 1 and is connected in series with the switch 4. The number of the light-emitting tubes 5 is the same as the number of the detection slots, and several light-emitting tubes 5 are connected in parallel.

[0058] The trigger section 213 is located between the limiting section 212 and the switch 4 .

[0059] In this technical solution, the circuit board 3 is located within the housing 11, adjacent to the second mounting plate 13, providing space for the switch 4. Switches 4 are positioned on the circuit board 3 in corresponding locations with the detection slots, ensuring that each detection slot has its own independent detection switch 4. When the trigger segment 213 of the stylus 21 is pushed by the pin 9, it accurately triggers the corresponding switch 4, thereby detecting the insertion of the pin 9.

[0060] The light emitting tubes 5 are arranged on the detector body 1 in series with the switches 4 and the same number as the detection slots, and a plurality of light emitting tubes 5 are connected in parallel. The detection results of each detection slot can be directly displayed through the independent light emitting tube 5. When the inserted pin 9 is inserted into the detection slot, the trigger section 213 pushes the switch 4 to close, and the corresponding light emitting tube 5 is turned on. The operator can directly understand the insertion of each pin 9. If the pin 9 is not inserted, the switch 4 remains open, and the light emitting tube 5 is not turned on, reminding the operator to adjust.

[0061] In use, when the to-be-detected object is inserted into the detection slot, the contact section 211 of the measuring needle 21 first contacts the pin 9, and as the pin 9 continues to be inserted, the trigger section 213 gradually approaches the switch 4. When the pin 9 is inserted, the trigger section 213 is moved to a distance that triggers the switch 4 to close, and the corresponding light emitting tube 5 is turned on, indicating that the pin 9 is detected to be qualified. If the light emitting tube 5 is not turned on, it means that the pin 9 at the corresponding position is not inserted, and needs to be adjusted or reinserted.

[0062] The adjusting sleeve 6 is arranged between the circuit board 3 and the second mounting plate 13.

[0063] In the technical scheme, the adjusting sleeve 6 is installed between the circuit board 3 and the second mounting plate 13, and the circuit board 3 is fixed on the adjusting sleeve 6 by bolts. The adjusting sleeve 6 can be used to adjust the distance between the circuit board 3 and the second mounting plate 13. In actual installation and use, due to factors such as manufacturing tolerance and assembly error, there may be a certain deviation between the distance between the circuit board 3 and the second mounting plate 13. By adjusting the thickness or length of the adjusting sleeve 6, the distance between the two can be accurately controlled, ensuring that the trigger section 213 of the measuring needle 21 can accurately trigger the switch 4 on the circuit board 3, improving the accuracy and reliability of detection. On the other hand, the adjusting sleeve 6 can also play a role in buffering and shock absorption. In the use process of the detection device, it may be subjected to external vibration or impact. The adjusting sleeve 6 can absorb and disperse these vibrations and impacts, protecting the circuit board 3 and the switch 4 from damage and prolonging the service life of the detection device.

[0064] The detector body 1 further comprises a to-position stop ring 7, which is arranged on the housing 11 and located outside the first mounting plate 12.

[0065] In the technical scheme, the to-position stop ring 7 is arranged on the housing 11 and located outside the first mounting plate 12. When the pin 9 is inserted into the detection slot, the first mounting plate 12 is inserted into the socket 10, and the to-position stop ring 7 can protect the first mounting plate 12 and the socket 10.

[0066] The housing 11 is provided with a battery 8, which is electrically connected with the circuit board 3, the switch 4 and the light-emitting tube 5.

[0067] In this technical solution, the battery 8 provided in the housing 11 provides power supply for the entire detection device. The provision of the battery 8 makes the detection device more portable and flexible. Without external power supply, the detection device can be used in various working environments and is not limited by the location of the power socket 10. It can be conveniently used for pin 9 insertion detection in production workshops, laboratories and on-site maintenance.

[0068] The battery 8 is electrically connected with the circuit board 3, the switch 4 and the light-emitting tube 5, ensuring that each component of the detection device can work normally. The battery 8 can provide stable voltage and current to ensure the normal operation of the circuit on the circuit board 3, the switch 4 can be accurately triggered, and the light-emitting tube 5 can clearly display the detection result.

[0069] At the same time, the battery 8 can also be designed as a rechargeable type, which can be charged when the power is insufficient, improving the sustainable use of the detection device.

[0070] The light-emitting tube 5 is arranged on the housing 11.

[0071] In this technical solution, the light-emitting tube 5 is arranged on the housing 11 to provide a stable mounting position for the light-emitting tube 5. The detection result is more intuitive and visible. The operator can directly observe the state of the light-emitting tube 5 from the housing 11 without opening the detection device. When the pin 9 is inserted in place, the corresponding light-emitting tube 5 lights up, clearly indicating the detection result. This intuitive display method greatly improves the efficiency and accuracy of detection and reduces human judgment errors.

[0072] The number of detection slots is three.

[0073] In this technical solution, three detection slots can simultaneously detect three pins 9, greatly improving the detection efficiency. In some occasions where a large number of pins 9 need to be quickly detected, such as electronic equipment production lines, this design can significantly shorten the detection time and improve the production efficiency.

[0074] The above is only a preferred embodiment of the present application and does not limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only a preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, which should be regarded as the protection scope of the present application.
