Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with quick-lock and anti-misinsertion functions. Background Technology

[0002] Connectors generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. Connectors often need to simultaneously transmit signals, data, and current. Therefore, the connector pins should be correctly inserted into the corresponding sockets. However, current connectors lack marking structures, making reverse insertion easy during the mating process.

[0003] Furthermore, existing connectors all use screws for fixing, which can lead to uneven stress on the connector due to inconsistent tightening forces during connection, making the connector prone to damage. Also, because screw connections require tools, the connector cannot be tightened quickly.

[0004] Therefore, connectors in the prior art have technical problems such as easy mis-insertion and inconvenient locking operation. Utility Model Content

[0005] This utility model provides a connector with quick-lock and anti-misinsertion functions, which solves the technical problems of easy misinsertion and inconvenient locking operation of connectors in the prior art.

[0006] Some implementation schemes for solving the above-mentioned technical problems include:

[0007] A connector with quick-lock and anti-misinsertion functions, including a plug;

[0008] and socket, wherein the plug is inserted into the socket;

[0009] The plug is provided with a locking hook, the socket is provided with a locking tongue that cooperates with the locking hook, the locking tongue is slidably connected to the socket, and an elastic element is provided between the locking tongue and the socket to push the locking tongue to cooperate with the locking hook;

[0011] Preferably, the plug is provided with a pin, the socket is provided with a socket that mates with the pin, and the plug is also provided with a protective frame to protect the pin. The protective frame is arranged around the pin, and the length of the protective frame extending out of the plug is greater than the length of the pin extending out of the plug.

[0012] Preferably, the plug and the protective frame are an integral structure, the positioning rib is disposed on the protective frame, and the positioning rib and the protective frame are an integral structure.

[0013] Preferably, the locking hook is disposed on the protective frame, and the locking hook and the protective frame are an integral structure. There are two locking hooks, and the two locking hooks are respectively located on both sides of the protective frame.

[0014] Preferably, the lock hook has a driving surface that pushes the lock tongue and causes the lock tongue to displace away from the lock hook against the force of the elastic element.

[0015] Preferably, the driving surface is inclined relative to the pin.

[0016] Preferably, the latch has an inclined surface that contacts the drive surface.

[0017] Preferably, the socket is provided with a groove to accommodate the latch, the latch is slidably connected to the groove, the elastic element is located in the groove, one end of the elastic element is fixed to the side wall of the groove, and the other end of the elastic element is fixed to the latch.

[0018] Preferably, the latch is further provided with an operating part that facilitates operation of the latch and disengagement of the latch from the lock hook.

[0019] Preferably, the operating part is an operating column, which extends out of the upper surface of the socket. The socket is provided with a strip groove, the length direction of which is arranged along the movement direction of the latch. The operating column extends out of the socket through the strip groove, and the latch and the operating column are an integral structure.

[0020] Compared with the prior art, the present invention has the following advantages:

[0021] By setting a locking hook and a locking tongue, and with the locking tongue slidingly connected to the socket, and an elastic element between the socket and the locking tongue, the locking tongue and the locking hook can quickly engage during the plug-socket assembly process. The engagement of the locking tongue and the locking hook locks the plug and socket together without the need for tools, making the assembly of the socket and plug very convenient.

[0022] In addition, by setting positioning ribs and positioning grooves, since the number of positioning ribs on the top surface of the plug is different from that on the bottom surface of the plug, the plug and socket will not be mis-inserted when they are mated, thus making it less likely to cause misoperation during the mating process and making the plug and socket easier to assemble.

[0033] The specific embodiments shown below are intended to describe various configurations of the subject matter of this invention and are not intended to represent the only configuration in which the subject matter of this invention can be practiced. The specific embodiments include detailed descriptions intended to provide a thorough understanding of the subject matter of this invention. However, it will be clear and apparent to those skilled in the art that the subject matter of this invention is not limited to the specific details shown herein and can be practiced without these specific details.

[0034] Understandably, in this document, relational terms such as “first” and “second” are intended to distinguish one entity or operation from another, and are not intended to expressly or imply any actual relationship or order between these entities or operations.

[0035] The terms “comprising,” “including,” or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase “comprising one…” does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0036] Reference Figures 1 to 6 As shown, a connector with quick-lock and anti-misinsertion functions includes a plug 1;

[0037] And socket 2, the plug 1 is inserted into the socket;

[0038] The plug 1 is provided with a locking hook 11, and the socket 2 is provided with a locking tongue 21 that cooperates with the locking hook 11. The locking tongue 21 is slidably connected to the socket 2, and an elastic element 22 is provided between the locking tongue 21 and the socket 2 to push the locking tongue 21 to cooperate with the locking hook 11.

[0039] The plug 1 is also provided with a positioning rib 12, and the socket 2 is provided with a positioning groove 23 that cooperates with the positioning rib 12. The top surface of the plug 1 is provided with at least one positioning rib 12, and the bottom surface of the plug 1 is provided with at least one positioning rib 12. The number of positioning ribs 12 on the top surface of the plug 1 is different from the number of positioning ribs 12 on the bottom surface of the plug 1.

[0040] Understandably, each positioning rib 12 is matched with an independent positioning groove 23. Since the number of positioning ribs 12 on the top surface of the plug 1 is different from that on the bottom surface of the plug 1, the plug 1 and the socket 2 can only be correctly connected when the top surface of the plug 1 corresponds to the top surface of the socket 2, thereby preventing the plug 1 and the socket 2 from being incorrectly connected.

[0041] Understandably, using the locking hook 11 and locking tongue 21 to lock the socket 2 and plug 1 is easier than using screws to lock them. Furthermore, since the locking tongue 21 and locking hook 11 do not require pre-tightening force, the plug 1 and socket 2 are subjected to even force, making them less prone to deformation and damage during long-term use.

[0042] Reference Figures 2 to 6 As shown, in some embodiments, the plug 1 is provided with a pin 13, the socket 2 is provided with a socket 24 that mates with the pin 13, and the plug 1 is also provided with a protective frame 14 to protect the pin 13. The protective frame 14 is arranged around the pin 13, and the length of the protective frame 14 extending out of the plug 1 is greater than the length of the pin 13 extending out of the plug 1.

[0043] The number of pins 13 is usually large, and due to the size limitation of the plug 1, the diameter of the pins 13 is generally small. The pins 13 are relatively fragile and prone to bending and deformation. Therefore, using a protective frame 14 to protect the pins 13 can prevent the pins 13 from being deformed by external forces and extend the service life of the plug 1.

[0044] Meanwhile, the protective frame 14 extends the length of the plug 1 beyond the length of the pin 13, further making the pin 13 less susceptible to external impact and extending the service life of the plug 1.

[0045] In some embodiments, the plug 1 and the protective frame 14 are an integral structure, the positioning rib 12 is disposed on the protective frame 14, and the positioning rib 12 and the protective frame 14 are an integral structure.

[0046] The positioning rib 12 can prevent the plug 1 from being mis-inserted into the socket 2. At the same time, the positioning rib 12 can also improve the strength of the protective frame 14, making the protective rib less prone to deformation. The protective rib can better play its protective function and extend the service life of the plug 1.

[0047] Reference Figures 2 to 6 As shown, in some embodiments, the locking hook 11 is disposed on the protective frame 14, the locking hook 11 and the protective frame 14 are an integral structure, there are two locking hooks 11, and the two locking hooks 11 are respectively located on both sides of the protective frame 14.

[0048] Understandably, the locking hook 11 is also provided on the protective frame 14 to increase the strength of the protective frame 14 and make the protective frame 14 less prone to deformation.

[0049] In some embodiments, the locking hook 11 has a driving surface 15, which pushes the locking tongue 21 and causes the locking tongue 21 to displace away from the locking hook 11 against the force of the elastic member 22.

[0050] In some embodiments, the drive surface 15 is inclined relative to the pin 13.

[0051] In some embodiments, the latch 21 has a bevel 25 that contacts the drive surface 15.

[0052] Understandably, the locking tongue 21 is located on the first locking surface, and the locking hook 11 is located on the second locking surface. The first and second locking surfaces are parallel to each other, and the sliding direction of the locking tongue 21 on the first locking surface is parallel to that of the first locking surface. The sliding direction of the locking tongue 21 is perpendicular to the insertion direction of the plug 1. Therefore, when the first and second locking surfaces are in contact, even if the plug 1 and socket 2 are pulled, the plug 1 and socket 2 will not detach because the first and second locking surfaces are in contact and interfere with each other.

[0053] Reference Figures 2 to 6 As shown, in some embodiments, the socket 2 is provided with a groove 26 for accommodating the latch 21, the latch 21 is slidably connected to the groove 26, the elastic member 22 is located in the groove 26, one end of the elastic member 22 is fixed to the side wall of the groove 26, and the other end of the elastic member 22 is fixed to the latch 21.

[0054] The groove 26 has a certain guiding function, which improves the displacement accuracy of the locking tongue 21. The elastic element 22 can be a spring, or the elastic element 22 can be replaced by other similar structures.

[0055] Understandably, the plug 1 and socket 2 are locked by the engagement of the locking tongue 21 and the locking hook 11. Besides being pushed by the elastic element 22, the locking tongue 21 can also be pushed by a screw rotatably connected to the socket 2. The locking tongue 21 has a screw hole that mates with the screw. When the locking tongue 21 is directly pushed by the screw, the locking tongue 21 has higher displacement accuracy relative to the socket 2, and the engagement between the locking tongue 21 and the locking hook 11 is more stable.

[0056] In some embodiments, the latch 21 is further provided with an operation part 27 for facilitating operation of the latch 21 and disengaging the latch 21 from the lock hook 11.

[0057] In some embodiments, the operating part 27 is an operating post that extends out of the upper surface of the socket 2. The socket 2 is provided with a strip groove 28, the length direction of which is arranged along the movement direction of the latch 21. The operating post extends out of the socket 2 through the strip groove 28, and the latch 21 and the operating post are an integral structure.

[0058] In addition to operating the locking tongue 21, the operating column can also mark the upper surface of the socket 2, further preventing the plug 1 and socket 2 from being mis-inserted.

[0059] The above describes the subject matter technical solution of this utility model and its corresponding details. It is understood that the above description is only some implementation schemes of the subject matter technical solution of this utility model, and some details may be omitted in the specific implementation.

[0060] Furthermore, in some embodiments of the above utility model, multiple embodiments may be combined; however, due to space limitations, all such combinations will not be listed here. Those skilled in the art can freely combine the above embodiments according to their needs to achieve a better application experience.

[0061] When implementing the subject matter technical solution of this utility model, those skilled in the art can obtain other detailed configurations or drawings based on the subject matter technical solution and the accompanying drawings. Obviously, these details are still within the scope of the subject matter technical solution of this utility model without departing from it.
