[0008] Furthermore, a blocking block is included, and a blocking block is provided at one end of the locking frame close to the unlocking frame.

[0009] Furthermore, it also includes a dust shield assembly. The dust shield assembly is provided inside the insertion slot of the second connector.

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present invention more apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear herein are based solely on the accompanying drawings and are not intended to limit the present invention.

[0033] An electronic connector with a reverse pull self-locking mechanism, such as Figures 1-11 As shown, it includes a first connector 1, a second connector 2, a contact 201, a rotating rod 3, a torsion spring 301, an extrusion plate 4, an unlocking frame 5 and a protrusion 501. The second connector 2 is provided with an insertion slot, and a contact 201 is provided inside the insertion slot. The side surface of the insertion slot entrance end is inclined. A connecting slot is provided inside the first connector 1. The first connector 1 can be inserted into the insertion slot of the second connector 2. A plurality of rotating rods 3 are rotatably provided on the four sides of the first connector 1. A torsion spring 301 is provided at the connection between the first connector 1 and the rotating rod 3. The rotating rod 3 on each side is rotatably connected to a squeezing plate 4 respectively. The upper sides of both ends of the squeezing plate 4 are inclined. An unlocking frame 5 is slidably provided on the first connector 1, and a plurality of protrusions 501 are provided on the inner side of the unlocking frame 5.

[0034] When connecting, insert the first connector 1 into the insertion slot of the second connector 2, and insert the contact piece 201 of the second connector 2 into the connection slot of the first connector 1. During the connection process, one end of the extrusion plate 4 contacts the second connector 2. Since the upper sides of both ends of the extrusion plate 4 are inclined, the extrusion plate 4 will gradually approach the first connector 1 and the unlocking frame 5 under the pressure of the second connector 2, until one side of the extrusion plate 4 is in contact with the inner side of the insertion slot of the second connector 2. At this time, the rotating rod 3 will rotate with its connection with the first connector 1 as the center of the circle, and the torsion spring 301 will deform; when the first connector 1 and the second connector 2 are in the connected state, if the first connector 1 is directly pulled outward, the first connector 1 will give the rotating rod 3 a rightward force, and between the rotating rod 3 and the torsion spring 301 Under the action, the extrusion plate 4 will be pushed outward toward the inner wall of the insertion groove of the second connector 2. Since the extrusion plate 4 is in contact with the side of the insertion groove of the second connector 2 at this time, the extrusion plate 4 will apply pressure to the second connector 2. This pressure will increase the friction between the extrusion plate 4 and the second connector 2, that is, the more the first connector 1 is pulled outward, the greater the friction between the extrusion plate 4 and the second connector 2, thereby achieving a self-locking effect; when it is necessary to unlock the connection between the first connector 1 and the second connector 2, the unlocking frame 5 is slid toward the second connector 2, and the protrusion 501 on the inner side of the unlocking frame 5 contacts one end of the extrusion plate 4. Under the action of the protrusion 501, the extrusion plate 4 is slightly close to the first connector 1, and the extrusion plate 4 is out of contact with the second connector 2. At this time, the first connector 1 can be directly pulled and pulled out.

[0035] like Figure 2 、 Figure 6 and Figure 7As shown, it also includes a locking frame 6, a sliding rod 601, a first elastic member 602 and a buffer assembly 7. The first connector 1 is slidably provided with a locking frame 6 on the upper and lower sides, a sliding rod 601 is provided on the locking frame 6, and a first elastic member 602 is sleeved on the outer side of the sliding rod 601. The first elastic member 602 connects the locking frame 6 and the first connector 1. A locking groove is provided in the insertion groove of the second connector 2, and the locking frame 6 can be embedded in the locking groove. The upper ends of the locking frame 6 are inclined and the middle part is concave, and a buffer assembly 7 is provided in the locking groove. During the connection process between the first connector 1 and the second connector 2, the locking frame 6 contacts the second connector 2. Due to the inclination of the upper ends of the locking frame 6, the locking frame 6 will slide toward the middle of the first connector 1 under the pressure of the second connector 2. When one end of the locking frame 6 moves to the locking groove position, the second connector 2 just stops pressing the locking frame 6. The locking frame 6 is reset under the action of the first elastic member 602, and one end of the locking frame 6 is embedded in the locking groove. When the first connector 1 is pulled, the locking frame 6 will hook the second connector 2, making it more difficult for the first connector 1 to be separated from the second connector 2. The buffer assembly 7 can play a buffering role, preventing the locking frame 6 from directly and rigidly contacting the second connector 2, thereby increasing the service life of the locking frame 6. When it is necessary to unlock the connection between the first connector 1 and the second connector 2, the unlocking frame 5 is slid toward the second connector 2. The unlocking frame 5 contacts the inclined surface of one end of the locking frame 6. The locking frame 6 slides toward the middle of the first connector 1 under the pressure of the unlocking frame 5, and the locking frame 6 is separated from the locking groove. At this time, the first connector 1 can be directly pulled out.

[0036] like Figure 7 and Figure 8As shown, the buffer assembly 7 includes a connecting rod 701, a buffer plate 702, a second elastic member 703, a blocking rod 704, a blocking member 705 and a third elastic member 706. A connecting rod 701 is provided in the locking groove of the second connector 2, and a buffer plate 702 is slidably provided on the connecting rod 701. Both sides of the lower end of the buffer plate 702 are inclined. A second elastic member 703 is sleeved on the outer side of the connecting rod 701. The second elastic member 703 connects the buffer plate 702 and the second connector 2. A blocking rod 704 is provided on the buffer plate 702. The blocking rod 704 is slidably connected to the second connector 2. A blocking member 705 is slidably provided in the locking groove of the second connector 2. A third elastic member 706 is connected between the blocking member 705 and the second connector 2. The blocking member 705 contacts the buffer plate 702, and the second elastic member 703 is in a compressed state. When the first connector 1 and the second connector 2 are not connected, the buffer plate 702 contacts the blocking member 705, the second elastic member 703 continues to apply pressure to the buffer plate 702, and the blocking member 705 prevents the buffer plate 702 from moving; when the first connector 1 and the second connector 2 are connected, one end of the locking frame 6 is embedded in the locking groove, the locking frame 6 squeezes the blocking member 705 to move, and causes the buffer plate 702 to disengage from the blocking member 705, and the buffer plate 702 contacts the locking frame 6. Under the action of the second elastic member 703, the buffer plate 702 continues to apply pressure to the locking frame 6. When pulling the first connector 1, the second elastic member 703 can play a buffering role to avoid damage caused by hard contact between the locking frame 6 and the second connector 2; when unlocking the connection between the first connector 1 and the second connector 2, the locking frame 6 moves under the pressure of the unlocking frame 5, the blocking member 705 is reset under the action of the third elastic member 706, and the blocking member 705 contacts the buffer plate 702 again.

[0037] like Figure 7 As shown, a blocking block 603 is also included, and a blocking block 603 is provided at one end of the locking frame 6 close to the unlocking frame 5. The blocking block 603 can block the unlocking frame 5 to prevent the unlocking frame 5 from moving excessively when unlocking.

[0038] like Figure 7 and Figure 9As shown, a dust shield assembly 8 is also included. The dust shield assembly 8 is provided inside the insertion slot of the second connector 2. The dust shield assembly 8 includes a dust shield plate 801 and a fourth elastic member 803. The dust shield plate 801 is slidably provided inside the insertion slot of the second connector 2. The dust shield plate 801 has multiple through holes 802 formed therein. The contact 201 is slidably connected to the through holes 802. The fourth elastic member 803 is connected between the second connector 2 and the dust shield plate 801. When the first connector 1 and the second connector 2 are not connected, the dust shield plate 801 protects the contact 201 from damage such as dust or debris. When the first connector 1 and the second connector 2 are connected, the dust shield plate 801 is squeezed and moved by the first connector 1, exposing the contact 201 through the through holes 802. When the first connector 1 is unplugged, the dust shield plate 801 is reset under the action of the fourth elastic member 803.

[0039] like Figure 2 、 Figure 7 and Figure 9 As shown, the dust shield assembly 8 further includes a sliding frame 804, an accordion plate 805, and a blocking block 102. The sliding frame 804 is provided on the dust shield 801, and a sliding groove is provided on the second connector 2. The sliding frame 804 is slidably connected to the sliding groove of the second connector 2. The accordion plate 805 is connected between the sliding frame 804 and the second connector 2 and is located in the sliding groove. The blocking block 102 is provided on the first connector 1. The sliding frame 804 ensures the stability of the dust shield 801 during movement. When the first connector 1 and the second connector 2 are not connected, the accordion plate 805 blocks the sliding groove of the second connector 2. When the first connector 1 and the second connector 2 are connected, the accordion plate 805 and the blocking block 102 together block the sliding groove, preventing dust or other debris from entering the sliding groove of the second connector 2 and protecting the contact 201 from damage.

[0040] like Figure 12-13 As shown, the unlocking frame 5 also includes a guide rod 502 and a limiting protrusion 104. The guide rod 502 is provided on the unlocking frame 5, and the first connector 1 is provided with a slide groove 103. The guide rod 502 is slidably connected to the slide groove 103 of the first connector 1, and a plurality of limiting protrusions 104 are provided inside the slide groove 103. The guide rod 502 can provide guidance for the sliding of the unlocking frame 5, preventing the unlocking frame 5 from deflecting and ensuring the accuracy and stability of the sliding direction of the unlocking frame 5. The limiting protrusions 104 can also play a certain limiting role, restricting the unlocking frame 5 to a specific position. When the unlocking frame 5 is not in use, the limiting protrusions 104 can fix it in the initial position to prevent accidental displacement due to external force or vibration. During the unlocking operation, the limiting protrusions 104 can fix the unlocking frame 5 in the unlocking position, preventing accidental displacement during unlocking and causing unlocking failure, and ensuring the stability of the unlocking frame 5 during unlocking.

[0041] like Figure 3-Figure 4As shown, a rubber pad 401 is also included. The rubber pad 401 is provided on the side of the extrusion plate 4 away from the first connector 1. The rubber pad 401 can increase the friction between the extrusion plate 4 and the second connector 2, further enhancing the self-locking effect. At the same time, the rubber pad 401 also has a certain buffering effect, which can reduce the wear between the extrusion plate 4 and the second connector 2 and extend the service life of the extrusion plate 4 and the second connector 2.

[0042] like Figure 2 and Figure 10 As shown, a gripping block 101 is also included, and the first connector 1 is provided with the gripping block 101. The gripping block 101 facilitates the operator to grip the first connector 1, facilitates operations such as insertion and removal, and improves the convenience and comfort of operation.
