Description

Technical Field

[0001] The present invention relates to the field of electronic connectors, and particularly to an electronic connector with a reverse pulling self-locking mechanism. Background Art

[0002] An electronic connector is a device used to connect circuit boards, wires, or other electronic devices to achieve electrical signal transmission. It is usually composed of metal conductors and insulating materials, and can ensure efficient and reliable transmission of current or signals between different components. The designs of electronic connectors are diverse and applicable to various environmental conditions and application scenarios, and are widely used in everything from simple household appliances to complex communication systems and aerospace equipment. They not only improve the modularity of electronic products, facilitate production and maintenance, but also improve the reliability and durability of the equipment.

[0003] The common connection method of electronic connectors is the plug-in type. In many actual application scenarios, such as in an environment with vibration or impact, traditional electronic connectors are extremely vulnerable to external forces, resulting in loose connections. In severe cases, accidental disconnection may even occur. This unstable connection phenomenon will directly lead to signal transmission interruption, affect normal data interaction, and at the same time cause abnormal power supply, seriously interfering with the operation of equipment that relies on stable power supply. Summary of the Invention

[0004] In order to overcome the shortcomings of traditional electronic connectors being vulnerable to external forces and causing loosening or even disconnection, the present invention provides an electronic connector with a reverse pulling self-locking mechanism.

[0005] The technical solution is: An electronic connector with a reverse pulling self-locking mechanism includes a first connector, a second connector, contact members, rotating rods, torsion springs, pressing plates, unlocking frames, and protrusions. The second connector is provided with an insertion slot, and contact members are arranged inside the insertion slot. The side at the entrance end of the insertion slot is inclined. The first connector is internally provided with a connection socket, and the first connector can be inserted into the insertion slot of the second connector. A plurality of rotating rods are rotatably arranged on four sides of the first connector, and torsion springs are arranged at the connection points between the first connector and the rotating rods. The rotating rods on each side are respectively rotatably connected to a pressing plate. The upper sides at both ends of the pressing plate are inclined. An unlocking frame is slidably arranged on the first connector, and a plurality of protrusions are arranged inside the unlocking frame.

[0006] Furthermore, it also includes a locking frame, sliding rods, a first elastic member, and a buffer assembly. Locking frames are slidably arranged on both the upper and lower sides of the first connector. Sliding rods are arranged on the locking frames, and a first elastic member is sleeved outside the sliding rods. The first elastic member connects the locking frame and the first connector. Locking slots are opened in the insertion slot of the second connector, and the locking frames can be embedded into the locking slots. The upper sides at both ends of the locking frame are inclined and the middle is concave, and a buffer assembly is arranged in the locking slot.

[0007] Furthermore, the buffer assembly includes a connecting rod, a buffer plate, a second elastic member, a blocking rod, a blocking member and a third elastic member. A connecting rod is provided in the locking groove of the second connector. A buffer plate is slidably provided on the connecting rod. Both sides of the lower end of the buffer plate are inclined. A second elastic member is sleeved outside the connecting rod. The second elastic member connects the buffer plate and the second connector. A blocking rod is provided on the buffer plate. The blocking rod is slidably connected to the second connector. A blocking member is slidably provided in the locking groove of the second connector. A third elastic member is connected between the blocking member and the second connector. The blocking member contacts the buffer plate. The second elastic member is in a compressed state.

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

[0009] Furthermore, a dust-proof assembly is further included. A dust-proof assembly is provided inside the insertion groove of the second connector. The dust-proof assembly includes a dust-proof plate and a fourth elastic member. A dust-proof plate is slidably provided in the insertion groove of the second connector. A plurality of through holes are formed in the dust-proof plate. The contact member is slidably connected to the through holes. A fourth elastic member is connected between the second connector and the dust-proof plate.

[0010] Furthermore, the dust-proof assembly further includes a sliding frame, a bellows plate and a shielding block. A sliding frame is provided on the dust-proof plate. A sliding groove is provided on the second connector. The sliding frame is slidably connected to the sliding groove of the second connector. A bellows plate is connected between the sliding frame and the second connector. The bellows plate is located in the sliding groove. A shielding block is provided on the first connector.

[0011] Furthermore, a guide rod and a limiting protrusion are further included. A guide rod is provided on the unlocking frame. A sliding groove is provided on the first connector. The guide rod is slidably connected to the sliding groove of the first connector. A plurality of limiting protrusions are provided inside the sliding groove.

[0012] Furthermore, a rubber pad is further included. A rubber pad is provided on the side of the pressing plate away from the first connector.

[0015] 2. Through the combination of the locking frame, sliding rod, first elastic member, and buffer assembly, when the first connector is connected to the second connector, the locking frame is inserted into the locking groove and further hooks the second connector, making the connection more difficult to disengage; the buffer assembly plays a buffering role to prevent the locking frame from directly contacting the second connector rigidly, increasing the service life of the locking frame and improving the connection reliability.

[0016] 3. Through the design of the dust-proof assembly, the present invention can reduce the exposure of the contact members, effectively prevent the contact members from being damaged due to factors such as dust or debris, and extend the service life of the connector.

[0017] 4. The present invention provides guidance for the sliding of the unlocking frame through the guide rod to prevent deviation, ensuring the accuracy and stability of the sliding direction of the unlocking frame; the limiting protrusion restricts the unlocking frame to a specific position, fixing it at the initial position in the non-use state and at the unlocking position during the unlocking operation, preventing accidental displacement and ensuring the unlocking stability.

Detailed implementation manners

[0032] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It is hereby declared that the directional terms such as upper, lower, left, right, front, rear, inner, and outer that appear or will appear in the text of the present invention are only based on the drawings of the present invention, and they do not specifically limit the present invention.

[0033] An electronic connector with a reverse pulling self-locking mechanism, as Figures 1-11 shown, includes a first connector 1, a second connector 2, a contact member 201, a rotating rod 3, a torsion spring 301, a pressing plate 4, an unlocking frame 5, and a convex block 501. The second connector 2 is provided with an insertion slot, and a contact member 201 is arranged inside the insertion slot. The side of the entrance end of the insertion slot is inclined. The first connector 1 is internally provided with a connection slot, and the first connector 1 can be inserted into the insertion slot of the second connector 2. A plurality of rotating rods 3 are rotatably arranged on four sides of the first connector 1. A torsion spring 301 is arranged at the connection part between the first connector 1 and the rotating rod 3. Each rotating rod 3 on each side is respectively rotatably connected to a pressing plate 4. The upper sides of both ends of the pressing plate 4 are inclined. An unlocking frame 5 is slidably arranged on the first connector 1, and a plurality of convex blocks 501 are arranged inside 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 201 of the second connector 2 into the connection slot of the first connector 1. During the connection process, one end of the pressing plate 4 contacts the second connector 2. Since the upper sides of both ends of the pressing plate 4 are inclined, the pressing 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 pressing plate 4 fits against the inner side of the insertion slot of the second connector 2. At this time, the rotating rod 3 will rotate around its connection point with the first connector 1, 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 outwards, the first connector 1 will exert a rightward force on the rotating rod 3. Under the action of the rotating rod 3 and the torsion spring 301, the pressing plate 4 will expand outwards towards the inner wall of the insertion slot of the second connector 2. Since the pressing plate 4 is in contact with the side surface of the insertion slot of the second connector 2 at this time, the pressing plate 4 will exert a pressure on the second connector 2, and this pressure will increase the friction between the pressing plate 4 and the second connector 2, that is, the more the first connector 1 is pulled outwards, the greater the friction between the pressing plate 4 and the second connector 2, achieving a self-locking effect. When it is necessary to unlock the connection between the first connector 1 and the second connector 2, slide the unlocking frame 5 towards the second connector 2. The convex block 501 inside the unlocking frame 5 contacts one end of the pressing plate 4. The pressing plate 4 will slightly approach the first connector 1 under the action of the convex block 501, and the pressing plate 4 will be disengaged from the second connector 2. At this time, the first connector 1 can be directly pulled out.

[0035] Such as Figure 2 , Figure 6 and Figure 7As shown in the figure, it further includes a locking frame 6, a sliding rod 601, a first elastic member 602 and a buffer assembly 7. Locking frames 6 are slidably provided on both the upper and lower sides of the first connector 1. A sliding rod 601 is provided on the locking frame 6, and a first elastic member 602 is sleeved outside the sliding rod 601. The first elastic member 602 connects the locking frame 6 and the first connector 1. A locking groove is formed in the insertion groove of the second connector 2, and the locking frame 6 can be embedded into the locking groove. The two ends of the upper side of the locking frame 6 are inclined and the middle part is sunken. A buffer assembly 7 is provided in the locking groove. During the connection process of the first connector 1 and the second connector 2, the locking frame 6 contacts the second connector 2. Due to the inclination of the two ends of the upper side of the locking frame 6, the locking frame 6 will slide towards 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 position of the locking groove, the second connector 2 no longer presses the locking frame 6. The locking frame 6 resets under the action of the first elastic member 602, and one end of the locking frame 6 is embedded into the locking groove. When pulling the first connector 1, the locking frame 6 will hook the second connector 2, making it more difficult for the first connector 1 to be disengaged from the second connector 2. The buffer assembly 7 can play a buffering role to avoid direct hard contact between the locking frame 6 and the second connector 2 and increase 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, slide the unlocking frame 5 towards the second connector 2. The unlocking frame 5 contacts the inclined surface of one end of the locking frame 6, and the locking frame 6 slides towards the middle of the first connector 1 under the pressure of the unlocking frame 5. The locking frame 6 disengages from the locking groove, and at this time, the first connector 1 can be directly pulled out.

[0036] As 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. The connecting rod 701 is provided in the locking groove of the second connector 2. The buffer plate 702 is slidably provided on the connecting rod 701. Both sides of the lower end of the buffer plate 702 are inclined. The second elastic member 703 is sleeved outside the connecting rod 701. The second elastic member 703 connects the buffer plate 702 and the second connector 2. The blocking rod 704 is provided on the buffer plate 702. The blocking rod 704 is slidably connected to the second connector 2. The 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. 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 continuously applies pressure to the buffer plate 702. 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 into the locking groove. The locking frame 6 squeezes the blocking member 705 to move and makes the buffer plate 702 disengage from the blocking member 705. The buffer plate 702 contacts the locking frame 6. Under the action of the second elastic member 703, the buffer plate 702 continuously applies 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 resets under the action of the third elastic member 706. The blocking member 705 contacts the buffer plate 702 again.

[0037] As Figure 7 shown, it further includes a blocking block 603. 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 during unlocking.

[0038] As Figure 7 and Figure 9As shown, it further includes a dust-proof component 8. A dust-proof component 8 is provided inside the insertion slot of the second connector 2. The dust-proof component 8 includes a dust-proof plate 801 and a fourth elastic member 803. The dust-proof plate 801 is slidably arranged in the insertion slot of the second connector 2. A plurality of through holes 802 are formed in the dust-proof plate 801, and the contact member 201 is slidably connected to the through holes 802. A fourth elastic member 803 is connected between the second connector 2 and the dust-proof plate 801. When the first connector 1 and the second connector 2 are not connected, the dust-proof plate 801 can protect the contact member 201 from being damaged by factors such as dust or sundries. When the first connector 1 and the second connector 2 are connected, the dust-proof plate 801 will be pushed and moved by the first connector 1, and the contact member 201 will be exposed through the through holes 802. When the first connector 1 is pulled out, the dust-proof plate 801 will reset under the action of the fourth elastic member 803.

[0039] As Figure 2 , Figure 7 and Figure 9 shown, the dust-proof component 8 further includes a sliding frame 804, a bellows plate 805 and a shielding block 102. A sliding frame 804 is provided on the dust-proof plate 801, a sliding groove is provided on the second connector 2, and the sliding frame 804 is slidably connected to the sliding groove of the second connector 2. A bellows plate 805 is connected between the sliding frame 804 and the second connector 2. The bellows plate 805 is located in the sliding groove, and a shielding block 102 is provided on the first connector 1. The sliding frame 804 can ensure the stability of the dust-proof plate 801 during movement. When the first connector 1 and the second connector 2 are not connected, the bellows plate 805 can cover the sliding groove of the second connector 2; when the first connector 1 and the second connector 2 are connected, the bellows plate 805 and the shielding block 102 together cover the sliding groove to prevent dust or other sundries from entering the second connector 2 from the sliding groove and avoid damage to the contact member 201.

[0040] As Figures 12-13 shown, it further includes a guide rod 502 and a limit projection 104. A guide rod 502 is provided on the unlocking frame 5, a sliding groove 103 is provided on the first connector 1, and the guide rod 502 is slidably connected to the sliding groove 103 of the first connector 1. A plurality of limit projections 104 are provided inside the sliding groove 103. The guide rod 502 can provide a guiding function for the sliding of the unlocking frame 5, prevent the unlocking frame 5 from shifting, and ensure the accuracy and stability of the sliding direction of the unlocking frame 5. The limit projection 104 can play a certain limiting role to limit the unlocking frame 5 at a specific position. When the unlocking frame 5 is in a non-use state, the limit projection 104 can fix it in the initial position to prevent accidental displacement caused by external force or vibration; during the unlocking operation, the limit projection 104 can fix the unlocking frame 5 in the unlocking position to prevent accidental displacement during unlocking, resulting in unlocking failure, and ensure the stability of the unlocking frame 5 during unlocking.

[0041] As Figures 3-4As shown, it further includes a rubber pad 401. A 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] As Figure 2 and Figure 10 shown, it further includes a gripping block 101. A gripping block 101 is provided on the first connector 1. The gripping block 101 facilitates the operator to grip the first connector 1, making it convenient for operations such as insertion and extraction, and improving the convenience and comfort of the operation.
