An electrical connector with locking function

Abstract

This utility model relates to the field of connector technology, and more particularly to an electrical connector with a locking function. The electrical connector with a locking function provided by this utility model solves the technical problem of poor sealing performance in existing connectors. An electrical connector with a locking function includes a plug; a socket, the plug being inserted into the socket; and a locking assembly for connecting the plug and the socket. By providing a locking cylinder, the plug and socket are connected using the locking cylinder. Rotating the locking cylinder relative to the plug and socket causes the plug and socket to move closer or further apart due to the positive and negative internal threads within the locking cylinder. During the assembly process, the plug does not need to rotate relative to the socket to complete the assembly, which can accommodate connectors of different specifications. The contact point between the plug and socket is located inside the locking cylinder, giving the connector good sealing performance, preventing dust and liquid from easily entering the socket.

Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an electrical connector with a locking function. Background Technology

[0002] Connectors, also known domestically as plugs, sockets, or connectors, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. Connectors are components frequently encountered by electronic engineers. Their function is very simple: to bridge gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0003] In existing technologies, connectors typically use screws or threads to fix the plug and socket together. When directly using threads to fix the plug and socket, the connector requires the plug to rotate relative to the socket during assembly, which is not suitable for multi-pin connectors. When using screws to connect the plug and socket, it can accommodate multi-pin connectors; however, when using screws to connect the plug and socket, the seal between the plug and socket is poor, and dust or liquid can easily enter the socket.

[0004] Therefore, connectors in the prior art have the technical problem of poor sealing. Utility Model Content

[0005] This utility model provides an electrical connector with a locking function, which solves the technical problem of poor sealing performance of connectors in the prior art.

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

[0007] An electrical connector with a locking function includes a plug;

[0008] A socket into which the plug is inserted;

[0009] and a locking assembly for connecting the plug to the socket;

[0010] The locking assembly includes a locking cylinder, with a positive internal thread and a negative internal thread respectively at both ends. The socket is provided with an external thread that mates with the positive internal thread, and the plug is provided with an external thread that mates with the negative internal thread. The locking cylinder drives the plug and the socket to move closer or further apart.

[0011] The socket is provided with a first shoulder, the plug is provided with a second shoulder, a first sealing ring is provided between the first shoulder and the locking cylinder, a second sealing ring is provided between the second shoulder and the locking cylinder, and a third sealing ring is provided between the plug and the socket.

[0012] Preferably, the plug is provided with pins, and the plug is also provided with a protective sleeve to protect the pins. The outer wall of the protective sleeve has a polygonal cross-sectional shape. The socket is provided with a socket hole that mates with the pins, and the socket is also provided with a hole that mates with the protective sleeve.

[0013] Preferably, the socket is provided with a first operating part, the cross-sectional shape of which is a regular polygon.

[0014] Preferably, the first shoulder and the socket are an integral structure, and the first operating part and the socket are an integral structure.

[0015] Preferably, the plug is provided with a second operating part, the cross-sectional shape of which is a regular polygon.

[0016] Preferably, the second shoulder and the plug are integrated into one structure, and the second operating part and the plug are integrated into one structure.

[0017] Preferably, the outer wall of the locking cylinder has a polygonal cross-sectional shape, and the pitch of the positive internal thread is equal to that of the negative internal thread.

[0018] Preferably, the first sealing ring has a first sealing ridge on each side, the first shoulder and the locking cylinder are respectively provided with a first sealing groove that cooperates with the first sealing ridge, and the first sealing ridge and the first sealing ring are an integral structure.

[0019] Preferably, the second sealing ring has a second sealing ridge on each side, the second shoulder and the locking cylinder have a second sealing groove that mates with the second sealing ridge, and the second sealing ridge and the second sealing ring are an integral structure.

[0020] Preferably, the third sealing ring includes a body and a first annular ridge disposed on the body. The first annular ridge protrudes from both sides of the body. The socket and the plug are both provided with notches to accommodate the first annular ridge. The body is also provided with a second annular ridge, which extends from both sides of the body. The socket and the plug are both provided with second annular grooves that mate with the second annular ridge. The first annular ridge and the second annular ridge are both integrally formed with the body.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By incorporating a locking cylinder with both forward and reverse internal threads, and external threads on the plug and socket respectively, the plug and socket are connected using the locking cylinder. Rotating the locking cylinder relative to the plug and socket causes the forward and reverse internal threads within the locking cylinder to move the plug and socket closer together or further apart. During the assembly process, the plug does not need to rotate relative to the socket to complete the assembly, which can accommodate connectors of different specifications. At the same time, the contact point between the plug and socket is located inside the locking cylinder, giving the connector good sealing performance and preventing dust and liquid from easily entering the socket.

[0023] By setting a first sealing ring, a second sealing ring, and a third sealing ring, the first sealing ring, the second sealing ring, and the third sealing ring form a multiple sealing effect, which further makes it difficult for dust and liquid to enter the socket, improves the stability of the connector, and extends the service life of the connector.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] Reference Figures 1 to 7 As shown, an electrical connector with a locking function includes a plug 2;

[0040] Socket 1, the plug 2 is inserted into socket 1;

[0041] and locking assembly 3, the locking assembly 3 being used to connect the plug 2 and the socket 1;

[0042] The locking assembly 3 includes a locking cylinder 31, with a positive internal thread and a negative internal thread respectively at both ends. The socket 1 is provided with an external thread that mates with the positive internal thread, and the plug 2 is provided with an external thread that mates with the negative internal thread. The locking cylinder 31 drives the plug 2 and the socket 1 to move closer or further apart.

[0043] The socket 1 is provided with a first shoulder 11, the plug 2 is provided with a second shoulder 21, a first sealing ring 32 is provided between the first shoulder 11 and the locking cylinder 31, a second sealing ring 33 is provided between the second shoulder 21 and the locking cylinder 31, and a third sealing ring 34 is provided between the plug 2 and the socket 1.

[0044] Specifically, during the assembly of plug 2 and socket 1, plug 2 is first aligned with socket 1. Then, the positive internal thread and the negative thread of locking cylinder 31 are respectively engaged with the external threads on plug 2 and socket 1. With plug 2 and socket 1 in a non-rotating state, rotating locking cylinder 31, under the action of the positive internal thread and the negative thread, brings plug 2 and socket 1 closer together, thereby completing the assembly and locking of the connector.

[0045] Understandably, as the plug 2 and socket 1 approach each other, they compress the third sealing ring 34, causing the third sealing ring 34 to deform and seal the contact point between the plug 2 and socket 1, preventing dust and liquid from entering the socket 1.

[0046] As the socket 1 and plug 2 approach each other, the distance between the first shoulder 11 and the locking cylinder 31 decreases, thereby squeezing the first sealing ring 32 and sealing the gap between the first shoulder 11 and the locking cylinder 31.

[0047] At the same time, the distance between the second shoulder 21 and the locking cylinder 31 decreases, thereby squeezing the second sealing ring 33 and sealing the gap between the second shoulder 21 and the locking cylinder 31.

[0048] In practice, the socket 1 and plug 2 can be positioned using tools. This positioning means that when the locking cylinder 31 is rotated, neither the plug 2 nor the socket 1 rotates with the locking cylinder 31. However, when the locking cylinder 31 is rotated, the plug 2 and socket 1 can move along the axial direction. For example, a wrench or other tools can be used to prevent the plug 2 and socket 1 from rotating with the locking cylinder 31.

[0049] Reference Figures 1 to 5 As shown, in some embodiments, the plug 2 is provided with a pin 23, and the plug 2 is also provided with a protective sleeve 22 to protect the pin 23. The outer wall of the protective sleeve 22 has a polygonal cross-sectional shape. The socket 1 is provided with a socket hole 12 that mates with the pin 23, and the socket 1 is also provided with a hole that mates with the protective sleeve 22.

[0050] The protective sleeve 22 can be made of metal. The protective sleeve 22 is used to protect the pin 23. At the same time, the protective sleeve 22 can also prevent the plug 2 from rotating relative to the socket 1. Therefore, the protective sleeve 22 may need to withstand a certain circumferential force. The protective sleeve 22 made of metal has higher strength and is not easily deformed.

[0051] In some embodiments, the socket 1 is provided with a first operating part 13, the first operating part 13 having a regular polygonal cross-sectional shape. The first operating part 13 is used to cooperate with tools such as wrenches to prevent the socket 1 from rotating relative to the plug 2.

[0052] In some embodiments, the first shoulder 11 and the socket 1 are integrally formed, and the first operating part 13 and the socket 1 are integrally formed.

[0053] In some embodiments, the plug 2 is provided with a second operating portion 24, the cross-sectional shape of which is a regular polygon. The second operating portion 24 is used to cooperate with tools such as wrenches to prevent the plug 2 from rotating relative to the socket 1.

[0054] In some embodiments, the second shoulder 21 and the plug 2 are integrally formed, and the second operating part 24 and the plug 2 are integrally formed.

[0055] In some embodiments, the outer wall of the locking cylinder 31 has a polygonal cross-sectional shape, and the pitch of the positive internal thread is equal to that of the negative internal thread.

[0056] The outer wall of the locking cylinder 31 has a polygonal cross-sectional shape, which allows the locking cylinder 31 to be easily rotated using tools such as wrenches. This makes the connector easy to assemble or disassemble.

[0057] Reference Figures 6 to 7 As shown, in some embodiments, the first sealing ring 32 is provided with a first sealing ridge 321 on both sides, the first shoulder 11 and the locking cylinder 31 are respectively provided with a first sealing groove that cooperates with the first sealing ridge 321, and the first sealing ridge 321 and the first sealing ring 32 are an integral structure.

[0058] In some embodiments, the second sealing ring 33 is provided with a second sealing ridge 331 on both sides, the second shoulder 21 and the locking cylinder 31 are respectively provided with a second sealing groove that cooperates with the second sealing ridge 331, and the second sealing ridge 331 and the second sealing ring 33 are an integral structure.

[0059] Reference Figure 6As shown, in some embodiments, the third sealing ring 34 includes a body 35 and a first annular ridge 36 disposed on the body 35. The first annular ridge 36 protrudes from both sides of the body 35. The socket 1 and the plug 2 are both provided with notches to accommodate the first annular ridge 36. The body 35 is also provided with a second annular ridge 37, which extends from both sides of the body 35. The socket 1 and the plug 2 are respectively provided with second annular grooves that cooperate with the second annular ridge 37. The first annular ridge 36 and the second annular ridge 37 are both integrally formed with the body 35.

[0060] Understandably, during the assembly or disassembly of plug 2 and socket 1, the relative displacement speed between plug 2 and socket 1 is controlled by the rotation speed of locking cylinder 31. Therefore, when assembling or disassembling socket 1, locking cylinder 31 can have a reasonable rotation speed so that pin 23 has a reasonable displacement speed relative to socket 12, preventing damage to pin 23 or socket 12.

[0061] Understandably, during assembly or disassembly of the plug 2 and socket 1, the plug 2 does not need to rotate relative to the socket 1, thus preventing damage to the pins 23. Furthermore, this also prevents the cables connected to the plug 2 or socket 1 from becoming tangled, optimizing the connector's performance.

[0062] 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.

[0063] 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.

[0064] 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.
