Description

Technical Field

[0001] The invention belongs to the technical field of electric devices, and in particular relates to a self-calibrating anti-dropping plug connector. Background Art

[0002] As a relatively simple electrical device, the structure and principle of the connector are relatively well known, that is, the external structure can fit and connect with each other, and the internal pins can be interconnected and conduct electricity. However, during the docking process of the ports and interfaces of the current mainstream quick-release and quick-install connectors, they are often prone to deviation and tilt, making it difficult to insert. If the insertion is not tight, if external force causes the interface to tilt, it is very easy to cause the pins in the port to bend due to force, making it very easy for the pins to tilt and unable to be inserted and docked during the plug-in process.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0005] A self-calibrating anti-dropping plug connector, comprising:

[0006] Connector port.

[0007] Connector interface.

[0008] The surface of the connector interface matches the shape of the inner wall of the connector port.

[0009] Pin pile.

[0010] The pin pile is movably connected to the inner wall of the connector port through a pin shaft.

[0011] A plurality of port pins are all penetrated and fixed on the surface of the pin pile, and a flat spring piece is integrally pressed and formed at one end of the port pin.

[0012] A plurality of fixed pins are sequentially arrayed and penetrated through the inner wall of the connector port and are fixed thereon, and are arranged at the same horizontal plane height as the corresponding port pins.

[0013] A pressing sheet is fixed on the surface of the pin pile, and the pressing sheet is attached to the surface of the connector port.

[0014] Top column.

[0015] The top column is fixed on the surface of the connector interface, and the end facing the pressing sheet is chamfered.

[0016] As a further solution of the present invention: the inner wall of the connector port is provided with a plurality of protection grooves for accommodating and protecting the port pins.

[0017] As a further solution of the present invention: two positioning grooves are provided on the surface of the connector port, and two positioning blocks corresponding to the heights of the positioning grooves are provided on the surface of the connector interface.

[0018] As a further solution of the present invention: a plurality of through holes are formed through the surface of the connector interface, and the inner wall of the through hole is interference-fitted with a terminal for mating with the port pins, and one end of the terminal is connected to a wiring.

[0019] As a further solution of the present invention: the surface of the connector port is provided with a latching tooth, and the surface of the connector interface is provided with a buckle that cooperates with the latching tooth for fastening.

[0020] As a further solution of the present invention: a pressing opening for exposing the terminal is provided on one side of the connector interface.

[0021] Beneficial effects:

[0022] This solution has an inclined design for the port pins at the connector port position. When the connector interface is not inserted, the port pins are located inside the protective groove for protection. In the event of oblique insertion, the pins will not be damaged because they are in a protected state. At the same time, the port pins and the fixed pins are in a separated state, and the static electricity will not affect the operational safety of the PCB board, reducing external interference. Only when the connector interface is aligned with the connector port, the top column presses the pressure plate to rotate the pin pile and move the port pin out of the protective groove so that it can be inserted into the terminal being entered, and the spring contacts the fixed pin to achieve connection. In this way, only the corresponding interface can be docked, which minimizes the possibility of damage to the port pins. When the non-matching connector interface is docked, the spring contact and the fixed pin have no contact and will not be connected, so the safety and reliability of use are high.

[0023] By adopting the design idea of ​​docking the two parts of the whole, the connector port and the connector interface are split into a docking design, and the pin lead-out surface is fixed as the bottom surface. The design is flat and square, and there will be no protrusions blocking the soldering on the PCB board surface.

[0024] The specific implementation modes of the present invention are further described in detail below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0034] Embodiment 1

[0035] See also Figures 1 to 6 The present invention provides a technical solution: a self-calibrating anti-dropping plug connector, comprising:

[0036] Connector port 1.

[0037] Connector interface 2.

[0038] The surface of the connector interface 2 matches the shape of the inner wall of the connector port 1 .

[0039] Pin pile 3.

[0040] The pin pile 3 is movably connected to the inner wall of the connector port 1 through a pin shaft.

[0041] A plurality of port pins 4 are all fixed through the surface of the pin pile 3 , and a flat spring piece 5 is integrally pressed and formed at one end of the port pin 4 .

[0042] A plurality of fixed pins 6 are sequentially arranged in an array and penetrate through the inner wall of the connector port 1 and are fixed thereto, and are arranged at the same level as the corresponding port pins 4 .

[0043] The pressing sheet 7 is fixed on the surface of the pin pile 3 , and the pressing sheet 7 is attached to the surface of the connector port 1 .

[0044] Top column 9.

[0045] Top column 9.

[0046] The top post 9 is fixed on the surface of the connector interface 2 , and the end facing the pressing piece 7 is chamfered.

[0047] By designing the port pin 4 to be tilted at the position of the connector port 1, the space occupied is reduced and the occupied space is minimized. When the connector interface 2 is not inserted, the port pin 4 is located inside the protective groove 8 for protection to ensure that it will not be damaged by foreign objects or be inserted obliquely. Since the pin is in a protected state, it will not be damaged. At the same time, the port pin 4 and the fixed pin 6 are in a separated state, and the operational safety of the PCB board will not be affected by static electricity, reducing external interference. Only when the connector interface 2 is aligned with the connector port 1, the top column 9 presses the pressure plate 7 to rotate the pin pile 3, and moves the port pin 4 out of the protective groove 8 so that it can be inserted into the terminal 10 being entered, and the spring 5 contacts the fixed pin 6 to achieve connection.

[0048] Embodiment 2

[0049] It is basically the same as the first embodiment, and the difference lies in that the spring piece 5 is directly fixed to the fixed pin 6, and the pin pile 3 fixes the port pin 4 toward the terminal 10, keeping the port pin 4 in a sliding connection state inside the pin pile 3.

[0050] The function of this embodiment is that the port pin 4 slides in the pin pile 3, canceling the original fixed state. When the port pin 4 is subjected to pressure, it can slide in the pin pile 3, and at the same time the spring piece 5 bends to unload the force, thereby reducing the force on the port pin 4.

[0051] Specifically, Figure 4 As shown: the inner wall of the connector port 1 is provided with a plurality of protection grooves 8 for accommodating and protecting the port pins 4.

[0052] By providing the protection groove 8 , the protection groove 8 can protect and accommodate the port pins 4 .

[0053] Specifically, Figure 2 As shown, two positioning grooves 15 are provided on the surface of the connector port 1 , and two positioning blocks 14 corresponding to the height of the positioning grooves 15 are provided on the surface of the connector interface 2 .

[0054] By providing the positioning groove 15 , the positioning groove 15 can cooperate with the positioning block 14 , so that the connector interface 2 can play a good guiding and limiting effect when docking with the connector port 1 , thereby ensuring a good and smooth plugging effect.

[0055] Specifically, Figure 3As shown: a plurality of through holes 16 are formed through the surface of the connector interface 2, and the inner wall of the through hole 16 is interference-fitted with a terminal 10 for mating with the port pin 4, and one end of the terminal 10 is connected to a wiring 11.

[0056] By providing the through hole 16 , the terminal 10 can be fixed by the through hole 16 , and the wiring 11 can pass through at the same time, so as to maintain a stable connection relationship.

[0057] Specifically, Figure 2 As shown: the surface of the connector port 1 is provided with a latching tooth 12 , and the surface of the connector interface 2 is provided with a buckle 13 that cooperates with the latching tooth 12 to fasten.

[0058] By providing the buckle 13, the cooperation between the buckle 13 and the locking tooth 12 can keep them connected and fixed to each other. This method is simple, reliable and convenient to use.

[0059] Specifically, Figure 1 As shown: a pressing opening 17 for exposing the terminal 10 is opened on one side of the connector interface 2.

[0060] The crimping opening 17 can facilitate the operation of the terminal 10 so as to fix the terminal 10 inside the through hole 16 .

[0061] The working principle of the present invention is:

[0062] S1. When the present solution is used, the connector interface 2 is aligned with the connector port 1 so that during the insertion process, the top post 9 first contacts the surface of the connector port 1. If the connector is inserted in reverse, the top post 9 cannot continue to be inserted due to the obstruction under the connector port 1, thereby achieving a foolproof effect;

[0063] S2. During the insertion process, the longest end of the connector interface 2 contacts the pressing piece 7, causing the pressing piece 7 to be pushed and deflected. Then the pressing piece 7 drives the pin pile 3 to rotate slightly. At this time, the port pin 4 slides out of the protection groove 8 during movement and points to the terminal 10. At the same time, during the movement of the port pin 4, the spring piece 5 at the other end moves accordingly and is tightly pressed against the surface of the fixed pin 6 to achieve connection;

[0064] S3. At the same time, as the terminal 10 is inserted into the surface of the fixed pin 6, the connection is completed, and the docking operation is completed after the buckle 13 and the tooth 12 cooperate to make a docking sound.

[0065] Combined with the above working principle, the following characteristics are summarized:

[0066] It can be pushed directly, which is simple and convenient to use. You only need to push it in directly without any other unnecessary operations.

[0067] Easy to disassemble, just separate the buckle 13 from the tooth 12 to separate directly;

[0068] When not docked, the port pin 4 and the fixed pin 6 are in a disconnected state and will not be in a connected state, which is safer and more reliable to use;

[0069] Retractable design of port pin 4.

[0070] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
