[0015] An apparatus using the connector includes the connector and further includes a PCB board, and the first plug is fixedly mounted on the PCB board.

[0016] The technical solution of the present application has the following advantages:

[0017] 1. The connector of the present application includes a first plug having an engaging portion; a second plug detachably connected to the first plug and having at least one locking tongue portion for locking the first plug and the second plug, the locking tongue portion fitting into the engaging portion; and at least one unlocking member detachably connected to the second plug and having an abutting portion, the unlocking member having a first state in which the locking tongue portion and the engaging portion are locked together, and a second state in which pressure is applied to the unlocking member to move the locking tongue portion away from the engaging portion via the abutting portion until the two are separated. When the connector of the present application is in the locked first state, the locking tongue portion and the engaging portion are locked together, and the connector is installed inside the first plug and the second plug to secure them together, which has the advantages of reducing the occupied space and saving materials, and solves the problem of adding elastic strikers or screws to both ends of the connector for fastening. When the second separated state is required, pressure is applied to the unlocking member, causing the abutment to move the locking tongue away from the engaging portion, thereby separating the locking tongue and engaging portion and driving the first and second plugs to separate. The locking tongue and engaging portion allow the first and second plugs to adapt to an operating environment with high-frequency vibrations after being securely connected, ensuring that poor contact due to vibrations does not occur during use of the connector.

[0018] 2. The connector of the present application further includes a fastener, wherein the first plug has a fastening end, the second plug has a first through-hole corresponding to the fastening end, and the unlocking member has a pivot portion with an accommodating space suitable for a fastening rod to pass through. The fastener passes through the first through-hole and the accommodating space and is then fixedly connected to the fastening end, thereby firmly connecting the first and second plugs. The connector of the present application includes a fastening end in the first plug, a first through-hole in the second plug, and an accommodating space between the pivot portion of the unlocking member, whereby the fastener passes through the first through-hole and the accommodating space and is then fixedly connected to the fastening end, ensuring the first and second plugs are firmly connected. The fastener is provided inside the connector to secure the first and second plugs, further improving their connection. The fastener allows the first and second plugs to better adapt to high-frequency vibration environments after being firmly connected, ensuring that poor contact due to vibration does not occur during use of the connector.

[0019] 3. In the connector of the present application, the fastener includes a fastening rod that fits the fastening end and a contact plate that is fixedly connected to the fastening rod, and a fastening ring is provided at the fastening end, and the fastening rod is screwed into the fastening ring to ensure the stability of the connection.

[0020] 4. In the connector of the present application, the center line of the first through hole and the center line of the receiving space of the pivot part are aligned coaxially with the center line of the fastening end, which ensures the precision of the fastener penetration and the accurate connection.

[0021] 5. In the connector according to the present application, the locking tongue portion is formed with a first elastic plate extending toward the second plug, the first elastic plate being fixedly connected to the second plug, the free end of the first elastic plate being the locking tongue portion, and the first plug and the second plug are engaged by mating the locking tongue portion with the engaging portion. The locking surface of the locking tongue portion is a first inclined surface, and correspondingly, the engaging surface of the engaging portion is a second inclined surface that matches the first inclined surface. The arrangement of the first and second inclined surfaces increases the contact area between the locking tongue portion and the engaging portion, further increasing the lock retention force between the first plug and the second plug, thereby preventing the first plug and the second plug from unlocking due to accidents or operational errors.

[0022] 6. In the connector of the present application, an accommodating groove is provided at one end of the first plug, and an engaging portion is formed at the end of the accommodating groove near the portion where the second plug is inserted, and the accommodating groove accommodates the locking tongue portion, so that the locking tongue portion engages with the engaging portion after entering the accommodating groove.

[0023] 7. In the connector of the present application, a pressing portion is connected to one end of the pivot portion of the unlocking member, and an abutting portion is connected to the other end. The pressing portion is provided on the outside of the second plug, and when an operator presses the pressing portion downward, the pivot portion acts as a rotation axis to drive the abutting portion, causing it to move upward.

[0024] 8. In the connector of the present application, the second plug is provided with an accommodation chamber that is compatible with the unlocking member, and a pivot part and a contact part are accommodated in the accommodation chamber, and the contact part abuts against the first elastic plate, and when the abutment part moves upward, it drives the first elastic plate to move upward, and the first elastic plate further drives the locking tongue part to move upward, thereby reducing the contact area between the first inclined surface of the locking tongue part and the second inclined surface of the engaging part until the locking tongue part and the engaging part are completely separated, thereby realizing axial separation of the first plug and the second plug.

[0025] 9. In the connector of the present application, an elastic element is provided between the accommodating chamber and the accommodating space of the pivot part, which prevents the unlocking member from moving arbitrarily into the accommodating chamber and also increases the tactile feel of the unlocking member during its movement.

[0026] 10. A device using the connector of the present application uses any of the connectors described above and has any of the advantages described above, and further includes a PCB board, wherein the first plug is fixedly mounted on the PCB board and the second plug is fixedly connected to the first plug via a fastener and a locking tongue portion.

[0032] Furthermore, the technical features according to the various embodiments of the present application described below can be combined with each other unless they are inconsistent.

[0033] 1 to 10 includes a first plug 1 and a second plug 2 that are removably connected, and the first plug 1 and the second plug 2 are fixedly connected via a fastener 4, and one unlocking member 3 that is removably connected is provided in the receiving chamber 205 of the second plug 2. Specifically, the fastener 4 is a screw, that is, the fastening rod 401 is a screw, and the abutment plate 402 is a nut.

[0034] As shown in Figure 7, the unlocking member 3 is suitable for locking and separating the first plug 1 and the second plug 2. The unlocking member 3 includes a pair of pivot portions 303 spaced apart, a pressing portion 301 at one end of the pivot portion 303, and an abutting portion 304 at the other end of the pivot portion 303, where the pressing portion 301, the pivot portion 303, and the abutting portion 304 are integrally molded. A gap is provided between the two pivot portions 303 to allow the fastening rod 401 to pass through the unlocking member 3, and the gap between the two pivot portions 303 is an accommodating space 305 for the pivot portion 303. To improve the connection with the second plug 2, a contact surface 302 is provided within the accommodating space of the pivot portion 303.

[0035] 1, 2, 5, and 6, the second plug 2 includes four contact points 207 and one locking tongue portion 203. One contact point 207 is provided on one side of the locking tongue portion 203, and three contact points 207 are provided on the other side. As shown in FIGS. 1, 2, and 6, the locking tongue portion 203 locks the first plug 1 and the second plug 2 together. A first elastic plate 202 extends from the locking tongue portion 203 toward the second plug 2. The free end of the first elastic plate 202 extending from the second plug 2 is the locking tongue portion 203. The first elastic plate 202 and the second plug 2 are integrally molded, and the locking surface of the locking tongue portion 203 is a first inclined surface 204. As shown in Figures 2 and 3, in order to accommodate the unlocking member 3, an accommodation chamber 205 is provided in the second plug 2, and the pivot portion 303 and abutment portion 304 of the unlocking member 3 are accommodated in the accommodation chamber 205, with the abutment portion 304 abutting against the underside of the first elastic plate 202. 2, to prevent the unlocking member 3 disposed within the receiving chamber 205 from moving arbitrarily, an elastic element is provided between the receiving chamber 205 and the receiving space 305 of the pivot part 303. The elastic element is a second elastic plate 206. That is, the second elastic plate 206 is fixedly provided on the side wall of the receiving chamber 205 facing the pivot part 303. The second elastic plate 206 is integrally molded with the second plug 2. One end of the second elastic plate 206 is fixed to the side wall of the receiving chamber 205, and the other end extends into the receiving space 305 of each pivot part 303. That is, the surface of the second elastic plate 206 is in close contact with the contact surface 302 of the receiving space 305. The extension of the second elastic plate 206 into the receiving space 305 of the pivot part 303 prevents the unlocking member 3 from moving arbitrarily within the receiving chamber 205 and increases the tactile feel of the unlocking member 3 during movement. The second plug 2 is provided with a first through hole 201 for easily passing the fastener 4 therethrough, and the first through hole 201 and the receiving space 305 of the pivot part 303 are arranged on the same central axis.

[0036] As shown in Figures 1 and 4, the first plug 1 includes four pins 104 and one receiving groove 101. Each pin 104 is provided with a corresponding contact point 207, and the receiving groove 101 is provided with a corresponding receiving chamber 205. The connector pins 104 and contact points 207 are the same in number and in one-to-one correspondence. To accommodate the locking tongue portion 203, an engaging portion is formed at the end of the receiving groove 101 near the portion that is inserted into the second plug 2, as shown in Figure 4. To increase the locking force between the first plug 1 and the second plug 2, the locking surface of the locking tongue portion 203 is a first inclined surface 204, and correspondingly, the engaging surface of the engaging portion is a second inclined surface 102 that matches the first inclined surface 204. To lock the fastener 4, the first plug 1 has a fastening end 103 corresponding to the first through hole 201, and the fastening end 103 includes an arrangement groove with an opening, in which a fastening ring that fits the fastening rod 401 is arranged, and a second through hole is provided in the side wall of the arrangement groove facing the second plug 2, and the fastening ring, the second through hole, the receiving space 305 of the pivot part 303, and the first through hole 201 are arranged coaxially. Specifically, the fastening ring is a nut.

[0037] The present application further provides a device using the connector, which includes the connector described above and further includes a PCB board, with the first plug 1 fixed to the PCB board.

[0038] In a specific implementation, when the first state for locking the locking tongue and the engaging portion needs to be reached, the on-site worker first moves the second plug 2 toward the first plug 1, and the locking tongue 203 at the free end of the first elastic plate 202 passes over the surface of the fastening end 103 until the first inclined surface 204 is in close contact with the second inclined surface 102 and then engages with the engaging portion. Then, the on-site worker uses a tool to extend the fastening rod 401 of the fastener 4 into the first through-hole 201, so that the fastening rod 401 passes through the first through-hole 201, the receiving space 305, and the second through-hole in sequence. Then, the on-site worker rotates the abutment plate 402 until the abutment plate 402 is in close contact with the end surface of the first through-hole 201, thereby screwing the fastening rod 401 into the fastening ring. When the second state in which the lock tongue portion and the engagement portion are separated is required, the on-site worker uses a tool to rotate the abutment plate 402 until the fastening rod 401 is retracted outside the first through hole 201, thereby separating the abutment plate 402 from the end face of the first through hole 201. The on-site worker then presses downward on pressing portion 301 of unlocking member 3, using pivot portion 303 as the axis of rotation to drive abutment portion 304 to move upward; because abutment portion 304 abuts against the underside of first elastic plate 202, as abutment portion 304 moves upward it drives first elastic plate 202 to move upward, and the first elastic plate 202 then drives locking tongue portion 203 to move upward, thereby reducing the contact area between first inclined surface 204 of locking tongue portion 203 and second inclined surface 102 of the engaging portion, and achieving axial separation of first plug 1 and second plug 2 until locking tongue portion 203 and the engaging portion are completely separated.

[0039] The connector of the present application has the advantages of small space occupation and strong connection, and is adaptable to high frequency vibration operating environments, ensuring that no poor contact problems caused by vibration will occur during use of the connector.

[0040] In alternative embodiments, the number of contact points 207 may be two, three, or more.

[0042] In alternative embodiments, the number of locking tangs 203 may be two, three, or more.

[0043] In alternative embodiments, the number of pins 104 may be two, three, or more.

[0044] In alternative embodiments, the number of pivot parts 303 may be one, three, four, or more. Taking the case where there is one pivot part 303 as an example, as shown in Figure 9, one side of the pivot part 303 is an accommodating space 305 through which the fastening rod 401 can pass.

[0045] In an alternative embodiment, as shown in FIG. 10, the abutting portions 304 abut on both ends of the first elastic plate 202 .

[0046] Alternatively, the elastic element may be a spring, one end of which is provided on the bottom surface of the receiving chamber 205 and the other end of which extends into the receiving space 305 of the pivot part 303, and the end of the spring which extends into the receiving space 305 is provided in close contact with the contact surface 302 of the receiving space 305. The spring is plugged into the second plug 2 and fitted.

[0047] In an alternative embodiment, the elastic element may be a bracket, one end of which is fixed to the bottom surface of the receiving chamber 205 and the other end of which extends into the receiving space 305 of the pivot part 303, and the end of the bracket that extends into the receiving space 305 is provided in close contact with the contact surface 302 of the receiving space 305. The bracket is integrally molded with the second plug 2.
