Description

Technical Field

[0001] The utility model belongs to the technical field of self-locking connectors, and particularly relates to a military connector with a self-locking function. Background Technique

[0002] Electrical connectors, also widely recognized as circuit connectors or electrical connectors, play a crucial role. They are like bridges that tightly connect two independent conductors in a circuit, ensuring the smooth transmission of current and signals, thereby realizing the integrity and efficiency of circuit functions.

[0003] Among the various forms of self-locking connectors, they can be mainly divided into five categories: straight plug type, knob type, slider type, pull rod type, and bolt type. Each type meets different application requirements with its unique locking mechanism. However, the current designs of self-locking connectors on the market often face a common problem - that is, there are numerous grooves and complex structures on the surface of the socket that closely cooperate with the plug locking structure. This design not only increases the complexity of manufacturing and assembly but also inevitably weakens the overall structural strength of the socket, posing a potential threat to its durability.

[0004] More critically, many existing self-locking connectors neglect the intuitive feedback mechanism for the locked state in their designs. This means that when the plug and the socket should be in an unlocked state, the connector cannot immediately provide clear feedback to the operator, increasing the risk of misoperation. The lack of this locking feedback is undoubtedly a major challenge to operation safety and efficiency.

[0005] Therefore, it is very necessary to invent a military connector with a self-locking function. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides a military connector with a self-locking function, which includes a socket, a plug locking part, a marking arrow, a locking ring, and a plug. The marking arrow is provided on both the socket and the plug locking part, and the locking ring is fixedly arranged on the socket; the plug is fixedly installed on the plug locking part.

[0007] The plug locking part includes a locking sleeve, an adapter ring cylinder, a clamping and fixing part, a feedback spring, and locking claws. The marking arrow is provided on the outer surface of the locking sleeve; the adapter ring cylinder is slidably sleeved in the locking sleeve, the clamping and fixing part is fixedly installed in the adapter ring cylinder, the plug is fixedly installed on the clamping and fixing part, and the feedback spring is sleeved and restricted; the locking claws are fixedly installed on the inner wall of the locking sleeve.

[0008] Preferably, the socket is provided with two identification arrows, which are respectively a locking indication and an unlocking indication; if the identification arrow of the plug locking member corresponds to the locking indication of the socket, it is in a locked state, and if it corresponds to the unlocking indication, it is in an unlocked state.

[0009] Preferably, two locking rings and two locking claws are provided in total, and a gap is provided between the two locking rings and locking claws, and the gap allows the other party to pass through; one of the identification arrows of the socket corresponds to the gap formed by the two locking rings.

[0010] Preferably, the locking sleeve can rotate outside the connecting ring tube, and the locking claw fixedly installed on the inner wall of the locking sleeve is an inwardly bent spring claw structure with deformation capability.

[0011] Preferably, the inner wall of the clamping fixture is provided with an annular groove, and the annular recess of the clamping fixture is used to restrict one end of the feedback spring therein, and the other end of the feedback spring has a flat surface, which allows contact with the socket.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model has significant advantages in improving the convenience of operation and the reliability of connection. By cleverly setting the marking arrows on the socket and the plug locking parts, as well as the intuitive locking and unlocking indicators on the socket, the operator can immediately identify the locking status of the plug and the socket, which greatly improves the operating efficiency and accuracy and reduces the risk of misoperation.

[0014] When designing the locking ring and locking claws, the needs of structural simplification and strength enhancement were carefully balanced. The ingenious gap design between the two locking rings and the locking claws not only ensures that they can smoothly pass through each other to achieve a secure lock, but also effectively avoids potential problems caused by overly complex structures, thereby significantly enhancing the overall structural strength of the socket, extending the product's service life and improving durability.

[0015] What is even more unique is that the locking sleeve is given rotational freedom and can flexibly rotate outside the connecting ring. At the same time, the locking claw adopts an advanced inward-bending spring claw structure, which gives the locking process excellent flexibility and fault tolerance. Even in the case of slight deviations, the spring claw can ensure reliable and stable locking between the plug and the socket with its excellent deformation ability, further improving the reliability of the connection.

[0016] It is particularly worth mentioning that the perfect combination of the carefully designed annular groove on the inner wall of the clamping fixture and the feedback spring not only accurately limits the position of the feedback spring but also ensures its efficient operation during the locking process. When the plug and the socket are not tightly locked, the elastic force of the feedback spring separates the two, serving as an intelligent feedback mechanism to assist in confirming the locking state through its unique elastic characteristics. Once the plug and the socket are successfully locked, the feedback spring stops functioning and awaits the next unlocking opportunity. In addition, when unlocking is required, the elastic force of the feedback spring can also help the two separate easily, effectively solving the problem of difficult unlocking in traditional designs and making the operation smoother.

[0024] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0025] A military connector with a self-locking function provided by the present invention includes a socket 1, a plug locking member 2, a marking arrow 3, a locking ring 4, and a plug 5. The marking arrow 3 is provided on both the socket 1 and the plug locking member 2, and the locking ring 4 is fixedly provided on the socket 1; the plug 5 is fixedly installed on the plug locking member 2.

[0026] The plug locking member 2 includes a locking sleeve 21, an adapter ring cylinder 22, a clamping and fixing member 23, a feedback spring 24, and a locking claw 25. The marking arrow 3 is provided on the outer surface of the locking sleeve 21; the adapter ring cylinder 22 is slidably sleeved in the locking sleeve 21, the clamping and fixing member 23 is fixedly installed in the adapter ring cylinder 22, the plug 5 is fixedly installed on the clamping and fixing member 23, and the feedback spring 24 is sleeved and restricted; the locking claw 25 is fixedly installed on the inner wall of the locking sleeve 21. Even in the case of slight deviation, the plug locking member 2 can ensure reliable and stable locking between the plug 1 and the socket 5 by virtue of its excellent deformation ability, further improving the reliability of the connection, and realizing an intelligent feedback mechanism through the elastic force, and assisting in confirming the locking state through its unique elastic force characteristics.

[0027] Embodiment 1:

[0028] Specifically, two of the said identification arrows 3 are provided on the socket 1, and the two said identification arrows 3 are respectively a locking indication and an unlocking indication; when the identification arrow 3 of the plug locking member 2 corresponds to the locking indication of the socket 1, it is in the locked state, and when it corresponds to the unlocking indication, it is in the unlocked state. The operator can distinguish the locking state of the plug 1 and the socket 5 through the identification arrow 3, which greatly improves the operation efficiency and accuracy and reduces the risk of misoperation.

[0029] Specifically, two locking rings 4 and two locking claws 25 are provided. There is a gap between the two locking rings 4 and the two locking claws 25, and this gap allows the other to pass through; one of the said identification arrows 3 on the socket 1 corresponds to the gap formed by the two locking rings 4. This not only ensures that the locking ring 4 and the locking claw 25 can smoothly pass through each other to achieve stable locking, but also effectively avoids potential problems brought by overly complex structures, thus significantly enhancing the overall structural strength of the socket, extending the service life of the product, and improving the durability.

[0030] Specifically, the locking sleeve 21 can rotate outside the connecting ring tube 22. The locking claw 25 fixedly installed on the inner wall of the locking sleeve 21 is a spring claw structure bent inward, and it has the ability to deform. The locking sleeve 21 is given rotational freedom and can flexibly rotate outside the connecting ring tube 22. At the same time, the locking claw 25 adopts an advanced spring claw structure bent inward, and this design endows the locking process with excellent flexibility and fault tolerance.

[0031] Specifically, there is an annular groove on the inner wall of the clamping and fixing member 23. The annular recess of the clamping and fixing member 23 is used to limit one end of the feedback spring 24 inside, and the other end of the feedback spring 24 has a flat surface, and this flat surface allows it to contact the socket 1. Relying on the elastic force of the feedback spring 24 to achieve an intelligent feedback mechanism. Once the plug 1 and the socket 5 are successfully locked, the feedback spring 24 stops acting. On the contrary, if the plug 1 and the socket 5 are not successfully locked, the feedback spring 24 forces them to be separated forcibly.

[0032] Embodiment 2:

[0033] On the socket 1, two clear identification arrows 3 are specially provided. These two arrows respectively represent a locking indication and an unlocking indication. When the identification arrow 3 on the plug locking member 2 is aligned with the locking indication on the socket 1, it means that the plug 1 and the socket 5 are correctly locked and in a safe connection state; on the contrary, if it is aligned with the unlocking indication, it indicates that the plug 1 and the socket 5 are in the unlocked or not fully connected state. This design greatly simplifies the judgment process of the locking state and improves the safety and convenience of the operation.

[0034] To simplify the design while ensuring structural strength, two locking rings 4 and two locking claws 25 are provided in this embodiment, and there is a clever notch between them. This notch design allows the locking ring 4 and the locking claw 25 to pass through each other during the locking process, thus achieving a stable connection. It should be noted that a marking arrow 3 on the socket 1 is specifically aligned with the notch formed by the two locking rings 4, which not only provides a visual confirmation of the locked state but also facilitates the operator to align the position during the locking operation.

[0035] The locking sleeve 21 is a key component in the plug locking member 2, and it can rotate outside the connecting ring cylinder 22. This rotational design enables the plug to flexibly adjust its angle when inserted into the socket 5 until it reaches the optimal locking position. At the same time, the locking claws 25 fixedly installed on the inner wall of the locking sleeve 21 adopt an inwardly bent spring claw structure, which endows the locking claws with excellent deformation ability. During the locking process, even if there is a slight deviation between the plug 1 and the socket 5, the locking claws 25 can achieve close fitting through their deformation ability, ensuring the stability and reliability of the connection.

[0036] The clamping and fixing member 23, as another important component in the plug locking member 2, has an annular groove on its inner wall to limit one end of the feedback spring 24. The other end of the feedback spring 24 has a flat surface that can contact the socket 1 and produce a feedback effect during the locking process. When the plug 1 and the socket 5 are fully locked, the elastic force of the feedback spring 24 is effectively constrained and no longer generates a separation force; while when unlocking is required, the feedback spring 24 can assist the separation operation of the plug 1 and the socket 5 through its elastic force, reducing the burden on the operator. This intelligent feedback mechanism not only improves the stability of the connection but also makes the unlocking process smoother.

[0037] Using the technical solution of the present utility model, or a person skilled in the art being inspired by the technical solution of the present utility model to design a similar technical solution and achieving the above technical effects shall fall within the protection scope of the present utility model.
