The upper surfaces of the first conductive part and the second conductive part are flush. The first conductive part and the second conductive part are connected to the positive and negative poles of the electric connector through a first conductive wire and a second conductive wire. When the length of the conductive insert of the plug is unqualified, the first conductive part and the second conductive part cannot connect the electric connector, thereby detecting the flatness of the conductive insert of the plug, ensuring the consistency of the length of the conductive insert on the plug, and solving the problem of poor plug quality.

[0007] As a preferred solution, the test seat includes a first mounting plate and a second mounting plate arranged separately.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0026] like Figs. 1-3 As shown, the utility model discloses a plug conductive plug flatness detection device, including a test socket and an electrical connector 30 for connecting an external device, the test socket is provided with a first slot 11 and a second slot 12 corresponding to the conductive plug on the plug, and the bottom of the first slot 11 and the second slot 12 is further provided with a first conductive member 211 and a second conductive member 231, the upper surfaces of the first conductive member 211 and the second conductive member 231 are flush, and the first conductive member 211 and the second conductive member 231 are connected to the positive and negative poles of the electrical connector 30 through a first conductive line 221 and a second conductive line 241 respectively; by setting the upper surfaces of the first conductive member 211 and the second conductive member 231 to be flush, when a plug with an unqualified conductive plug length is inserted, it cannot be connected to the electrical connector 30 through the first conductive member 211 and the second conductive member 231, thereby realizing the detection of the flatness of the conductive plug of the plug, ensuring that the length of the conductive plug on the plug is consistent, and solving the problem of poor plug quality.

[0027] The test seat includes a first mounting plate 10 and a second mounting plate 20 that are separately arranged, and the first slot 11 and the second slot 12 are arranged on the first mounting plate 10, and the first slot 11 and the second slot 12 both pass through the upper and lower surfaces of the first mounting plate 10; by separately arranging the first mounting plate 10 and the second mounting plate 20, it is convenient to maintain the detection device.

[0028] The second mounting plate 20 is provided with a first limiting groove 21 corresponding to the first conductive member 211 and a first routing groove 22 corresponding to the first conductive wire 221 on one side thereof. The second mounting plate 20 is further provided with a second limiting groove 23 corresponding to the second conductive member 231 and a second routing groove 24 corresponding to the second conductive wire 241 on one side thereof. When assembled, the first conductive member 211 and the first conductive wire 221 are respectively located in the first limiting groove 21 and the first routing groove 22, and the second conductive member 231 and the second conductive wire 241 are respectively located in the second limiting groove 23 and the first routing groove 24. In the positioning groove 23 and the second wiring groove 24, one end of the first wiring groove 22 is connected to the first limiting groove 21, and one end of the second wiring groove 24 is connected to the second limiting groove 23. The first wiring groove 22 is away from the end of the first limiting groove 21 and the second wiring groove 24 is away from the end of the second limiting groove 23. By setting the first limiting groove 21, the first wiring groove 22, the second limiting groove 23, and the second wiring groove 24 for limiting, the problem of displacement of the first conductive member 211, the first conductive wire 221, the second conductive member 231 and the second conductive wire 241 during long-term use is avoided, thereby improving detection reliability.

[0029] A first conductive bead 131 is provided in the first mounting plate 10 and protrudes into the first slot 11. A second conductive bead 141 is also provided in the first mounting plate 10 and protrudes into the second slot 12. A first detection member 151 and a second detection member 171 are provided between the first mounting plate 10 and the second mounting plate 20. The first conductive bead 131 is electrically connected to the first detection member 151 through a third conductive wire 161, and the second conductive bead 141 is electrically connected to the second detection member 171 through a fourth conductive wire 181. By providing the first detection member 151 and the second detection member 171, it is possible to detect whether a conductive plug is inserted into the first slot 11 and the second slot 12, thereby improving the accuracy of the detection.

[0030] It should be understood that the first detection member 151 and the second detection member 171 are both equipped with a built-in power supply, which transmits the electrical signal to the detection member through the conductive plug and the conductive bead, thereby triggering the detection member. The first detection member 151 and the second detection member 171 are both detection member structures commonly used by technicians in this field and will not be repeated here.

[0031] The first mounting plate 10 is provided with a first mounting groove 13 and a second mounting groove 14 which are respectively connected to the first slot 11 and the second slot 12. The first conductive bead 131 is arranged in the first mounting groove 13. The first mounting groove 13 is provided with a first elastic member 132 which makes the first conductive bead 131 always have a tendency to move into the first slot 11. The second conductive bead 141 is arranged in the second mounting groove 14. The second mounting groove 14 is provided with a second elastic member 142 which makes the second conductive bead 141 always have a tendency to move into the second slot 12. By providing the elastic member, the conductive plug can be easily inserted into the slot, and the feel of the conductive plug when inserted into the slot can be improved.

[0032] The first mounting plate 10 is recessed on one side relative to the second mounting plate 20 with a third limiting groove 15 corresponding to the first detecting member 151 and a third routing groove 16 corresponding to the third conductive wire 161. The first mounting plate 10 is further recessed on one side relative to the second mounting plate 20 with a fourth limiting groove 17 corresponding to the second detecting member 171 and a fourth routing groove 18 corresponding to the fourth conductive wire 181. During assembly, the first detecting member 151 and the third conductive wire 161 are respectively located in the third limiting groove 15 and the third routing groove 16, and the second detecting member 171 and the fourth conductive wire 181 are respectively located in the fourth limiting groove 17 and the fourth routing groove 18; the third routing groove 16 is connected to the first mounting groove 13, and the fourth routing groove 18 is connected to the second mounting groove 14; by providing the third limiting groove 15, the third routing groove 16, the fourth limiting groove 17 and the fourth routing groove 18, the first detecting member 151, the third conductive wire 161, the second detecting member 171 and the fourth conductive wire 181 are protected, thereby improving safety in use.

[0033] The first mounting groove 13 passes horizontally through the side wall of the first slot 11, and the second mounting groove 14 passes horizontally through the side wall of the second slot 12; the first mounting groove 13 and the second mounting groove 14 are coaxially arranged; the first mounting groove 13 is located on the side of the first slot 11 away from the second slot 12, and the second mounting groove 14 is located on the side of the second slot 12 away from the first slot 11; by setting the first mounting groove 13 and the second mounting groove 14 coaxially, the insertion feel of the first slot 11 and the second slot 12 is ensured to be consistent, thereby improving the user experience.

[0034] The method of using the present invention is as follows: connect the electrical connector 30 of the present invention to an external electronic device, then insert the conductive plug of the plug to be tested into the first slot 11 and the second slot 12, and the first detection member 151 and the second detection member 171 respectively detect whether the conductive plug is inserted into the first slot 11 and the second slot 12; when the tested plug is qualified, the two conductive plugs can respectively contact the first conductive member 211 and the second conductive member 231, thereby connecting the external electronic device; when the tested electrical connector 30 is unqualified, the external electronic device cannot be connected.

[0035] In summary, the present invention sets the upper surfaces of the first conductive member 211 and the second conductive member 231 to be flush. When a plug with an unqualified conductive plug length is inserted, the electrical connector 30 cannot be connected through the first conductive member 211 and the second conductive member 231. This allows the flushness of the conductive plugs of the plug to be detected, ensuring that the length of the conductive plugs on the plug is consistent, and improving the production quality of the electrical connector 30.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made to the above embodiments based on the technical practice of the present invention are still within the scope of the technical solution of the present invention.
