Description

Technical Field

[0001] This invention relates to the field of connector technology, and in particular to a connector locking structure and a connector. Background Technology

[0002] In the use of hybrid array connectors, plugs and sockets are typically secured using half-connecting rings based on a Haver structure. To ensure proper installation and prevent loosening, the half-connecting ring usually has a semi-circular ring structure, with four screws securing the two semi-circular rings together. However, during normal insertion and removal of the connector, the screws need to be manually tightened and loosened each time, resulting in a significant waste of manpower and resources. Furthermore, the screws securing the half-connecting rings are in constant contact with seawater, posing a risk of loosening and falling off. Even with adhesive applied to the screw threads, the complex marine environment can cause the adhesive to fail.

[0003] A schematic diagram of a conventional product structure is shown below. Figure 1 As shown. An existing screw 100 is installed on the side of an existing semi-connecting ring 200. A spring washer 300 is fitted onto the existing screw 100 and presses the spring washer 300 against the mating surface of the existing semi-connecting ring 200. Adhesive is applied to the screw threads. This product structure has the following drawbacks: 1. If the existing screw loosens, the existing semi-connecting ring will lose its radial fixing force. Loosening of the existing semi-connecting ring will cause the head and seat to lose their axial locking structure, ultimately leading to abnormal separation of the head and seat and loss of equipment; 2. The adhesive on the existing screw is a one-time use adhesive. The effectiveness of the adhesive will be greatly reduced when tightening the screw a second time, and replacing the existing screw each time is undoubtedly a waste of resources; 3. During the assembly of the existing screw, a spring washer 300 needs to be installed to prevent loosening. After repeated tightening, the elasticity of the spring washer will be affected, and there is a risk of loss; 4. Each time the screw is tightened, manual operation is required, wasting manpower and resources. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention proposes a quick-plug array connector locking structure and connector, which solves the problem that the existing array connector uses a screw-locked semi-connecting ring structure, which is not only cumbersome and inefficient, but also poses a risk of screw loosening in marine environments, potentially leading to connection failure.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A quick-plug array connector locking structure includes a plug assembly and a socket assembly that are mated for insertion. A shaped connecting ring is fastened to the outer side of the junction of the plug assembly and the socket assembly. A connecting nut is fitted onto one of the plug assembly and the socket assembly. An elastic locking component that can slide axially and rotate circumferentially is fitted onto the outer side of the shaped connecting ring, the connecting nut, and the corresponding component fitted with the connecting nut. A guide protrusion is provided at one end of the elastic locking component near the shaped connecting ring. The shaped connecting ring and the connecting nut are provided with guide grooves that respectively mate with the guide protrusion. The engagement of the guide protrusion with different guide grooves achieves locking or disengagement of the shaped connecting ring.

[0007] Furthermore, the socket assembly includes a socket housing and a socket sleeve fitted on the outer side of the end of the socket housing; the connecting nut is fitted on the outer side of the junction between the socket housing and the socket sleeve; the plug assembly includes a plug housing that is inserted into the socket housing.

[0008] Furthermore, the elastic locking assembly includes a spring sleeved on the outside of the irregular connecting ring, the connecting nut and the socket sleeve, and a locking cylinder sleeved on the outside of the spring; the socket sleeve and the locking cylinder are provided with radially extending bosses at their opposite ends for abutting against the two ends of the limiting spring.

[0009] Furthermore, the guide protrusion is a single key located on the inner side of the locking cylinder near the end of the irregular connecting ring; the outer side of the irregular connecting ring is provided with a strip-shaped guide groove that mates with the single key and extends axially.

[0010] Furthermore, the connecting nut is provided with a shaped guide groove, which includes an axial guide section, a circumferential limiting section and an axial locking section connected in sequence; the axial locking section extends in the opposite direction to the axial guide section; and the end of the axial locking section is closed, which is used to accommodate and lock the single key under the elastic force of the spring.

[0011] Furthermore, the outer periphery of the irregular connecting ring away from the socket housing has an outer ring platform that abuts against the end of the locking cylinder; the inner sides of both ends of the irregular connecting ring have inner ring platforms, and the outer periphery of the plug housing and the socket housing have grooves that respectively fit with the inner ring platforms.

[0012] Furthermore, the connecting nut is secured to the socket housing with screws.

[0013] A connector includes the quick-plug array connector locking structure described in any one of the above claims, and further includes a plug sleeve sleeved on the outer end of the plug housing. Both the plug sleeve and the socket sleeve are provided with a rope threading bracket, and both the plug sleeve and the socket sleeve are provided with a fixing sleeve for fixing an oil pipe to the plug sleeve and the socket sleeve respectively.

[0014] Furthermore, the connector is a hybrid optoelectronic connector, internally equipped with optical contacts and electrical contacts.

[0015] Furthermore, the connector is one of an electrical connector, an optical connector, or a fluid connector.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention adopts an elastic locking structure that combines a locking cylinder and a spring, replacing the traditional screw locking method, completely avoiding the risk of screw loosening, and significantly improving the reliability of the connector in a marine environment;

[0018] 2. This invention achieves rapid switching of the locking state by using a single key on the locking cylinder in conjunction with the U-shaped guide groove of the connecting nut. The locking and unlocking of the connector can be completed by a single person's twisting operation, which greatly improves the insertion and removal efficiency.

[0019] 3. The present invention provides a guide groove on the irregularly shaped connecting ring, so that when the guide groove on the irregularly shaped connecting ring is aligned with the locking cylinder key when the irregularly shaped connecting ring is rotated, the locking cylinder is pushed to the point where it is pressed against the protrusion of the irregularly shaped connecting ring under the action of spring force, thus completing the rapid locking of the connector.

[0020] 4. This invention eliminates the need for multiple locking screws and spring washers on the semi-connecting ring, simplifying the number of parts and reducing assembly complexity and production costs;

[0021] 5. The present invention adopts a two-piece sleeve and shell structure, which facilitates the assembly and maintenance of optical and electrical contacts and improves production efficiency;

[0022] 6. The present invention features a separate design for the rope threading bracket and the sleeve, which allows for flexible adjustment of the bracket structure according to the size of the Kevlar rope, thereby reducing processing difficulty and cost;

[0023] 7. This invention is not only applicable to optoelectronic hybrid connectors, but can also be extended to electrical connectors, optical connectors or fluid connectors, and has wide versatility and adaptability. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The quick-plug array connector locking structure described in Embodiment 1 of the present invention, such as... Figures 1 to 4 As shown, this structure is mainly used to achieve quick and reliable locking and unlocking between the plug and the socket, and is particularly suitable for segment connection scenarios that require frequent plugging and unplugging and have high requirements for connection reliability. The locking structure mainly includes a plug assembly and a socket assembly that are plugged into each other. To achieve the locking function, a shaped connecting ring 2 is fastened to the outside of the junction of the plug assembly and the socket assembly. Simultaneously, a connecting nut 8 is fitted onto one of the plug assembly and the socket assembly. In this embodiment, the connecting nut 8 being fitted onto the outside of the socket assembly is used as an example for explanation.

[0033] like Figure 1 As shown, an elastic locking component is fitted onto the outside of the irregular connecting ring 2, the connecting nut 8, and the corresponding component (i.e., the socket assembly) on which the connecting nut 8 is fitted. This elastic locking component is designed to slide axially and also rotate circumferentially within a certain range. Specifically, as... Figure 1 As shown, the elastic locking assembly includes a spring 5 and a locking cylinder 4. The spring 5 is sleeved on the outside of the irregular connecting ring 2, the connecting nut 8, and the socket assembly. The locking cylinder 4 is sleeved on the outside of the spring 5, enclosing the spring 5 inside. In order to axially limit the spring 5, the socket assembly is provided with a limiting structure that cooperates with the locking cylinder 4.

[0034] Furthermore, the elastic locking assembly has a guide protrusion at one end near the irregularly shaped connecting ring 2. Correspondingly, guide grooves are provided on both the irregularly shaped connecting ring 2 and the connecting nut 8. These guide grooves cooperate with the guide protrusion, facilitating the locking or disengagement of the irregularly shaped connecting ring 2 through the engagement of the guide protrusion with different guide grooves. Specifically, when the guide protrusion engages with the guide groove on the irregularly shaped connecting ring 2, the irregularly shaped connecting ring 2 is locked. When the guide protrusion engages with the guide groove on the connecting nut 8, the irregularly shaped connecting ring 2 is easily disassembled, thus achieving separation.

[0035] In one specific embodiment, the socket assembly includes a socket housing 10 and a socket sleeve 9 fitted onto the outer side of one end of the socket housing 10. The plug assembly includes a plug housing 1 that engages with the socket housing 10. The connecting nut 8 is fitted onto the outer side of the junction between the socket housing 10 and the socket sleeve 9.

[0036] like Figure 1 As shown, specifically, spring 5 is sleeved on the outside of the irregular connecting ring 2, connecting nut 8, and socket sleeve 9. Locking cylinder 4 is sleeved on the outside of spring 5, enclosing it. To axially limit the movement of spring 5, socket sleeve 9 and locking cylinder 4 have mutually cooperating structures: at the end of socket sleeve 9 furthest from locking cylinder 4 (i.e.... Figure 1 The right end of the locking cylinder 4 has a radially outwardly extending boss. Similarly, at the end of the locking cylinder 4 furthest from the socket sleeve 9 (i.e., Figure 1 The left end of the spring 5 also has a boss that extends radially inward or outward. These two bosses abut against the two ends of the spring 5 respectively, thereby restricting the spring 5 between the two ends so that it can provide a stable restoring force when compressed.

[0037] In addition, a sealing ring 3 is provided on the mating surface of the plug housing 1 and the socket housing 10; a sealing ring 7 is provided on the mating surface of the socket housing 10 and the socket sleeve 9. In this embodiment, both the sealing ring 3 and the sealing ring 7 are O-rings.

[0038] Example 2 differs from Example 1 in that, as a preferred embodiment, see [link to example]. Figure 3 The aforementioned guide protrusion is specifically a single key 41 located on the inner side of the locking cylinder 4 near the end of the irregular connecting ring 2. This single key 41 is a radially inwardly protruding key-like structure. Correspondingly, the outer side of the irregular connecting ring 2 is provided with an axially extending strip-shaped guide groove 21, such as... Figure 4 As shown. Furthermore, the opening of the strip guide groove 21 is an open trumpet shape, facilitating the alignment of the single key 41 with the opening of the strip guide groove 21. Then, through the restoring action of the spring, the single key 41 can be precisely inserted into the strip guide groove 21 and slide along its axis to the bottom of the strip guide groove 21. Under the action of the spring, the single key 41 will not slip out without external force, thus achieving a locking effect.

[0039] In addition, such as Figure 4 As shown, the irregular connecting ring 2 has a symmetrical two-lobed structure. Each irregular connecting ring 2 is provided with at least one strip guide groove 21. The locking cylinder 4 is provided with at least two single keys 41, which respectively cooperate with the strip guide grooves 21 on the two irregular connecting rings 2.

[0040] Example 3 differs from Example 2 in that, see [link to example 2] Figure 2 The connecting nut 8 has a specially shaped guide groove 81, which is not a simple straight groove but has a special shape. In this embodiment, the specially shaped guide groove 81 is approximately a "J"-shaped groove. Specifically, the specially shaped guide groove 81 includes three functional sections connected in sequence: an axial guide section, a circumferential limiting section, and an axial locking section. The axial guide section extends axially to facilitate the entry of the single key 41. After the single key 41 moves to the bottom along the axial guide section, by rotating the locking cylinder 4, the single key 41 can enter the circumferential limiting section connected to the axial guide section. The key improvement of this embodiment is that the end of the circumferential limiting section is also connected to an axial locking section, which also extends axially, but its extension direction is exactly opposite to that of the axial guide section, that is, the axial locking section extends towards the plug. The end of the axial locking section is closed. When the locking cylinder compresses the spring, it allows the single key 41 to move from the axial guide section to the circumferential limiting section, and then to the axial locking section. When the locking cylinder is released, the single key 41 is engaged in the axial locking section under the action of the spring's reset.

[0041] Since the single key 41 is located at the end of the locking cylinder 4 near the irregular connecting ring 2, after the single key 41 is inserted into the irregular guide groove 81, the irregular connecting ring 2 can be fully exposed, which makes it easy to quickly remove the irregular connecting ring 2.

[0042] Example 4 differs from Example 3 in that, as Figure 1 As shown, in order to further improve the stability of the structure and the connection strength, the end of the irregularly shaped connecting ring 2 away from the socket housing 10 (i.e., Figure 2 An outer ring platform is provided on the outer periphery of the left end of the locking cylinder 4. When the locking cylinder 4 is reset under the action of the spring 5, the outer ring platform just abuts against the end of the locking cylinder 4, which plays a role in limiting and supporting.

[0043] Meanwhile, the inner sides of both ends of the irregularly shaped connecting ring 2 are provided with inner ring platforms, and correspondingly, grooves that fit into these inner ring platforms are provided on the outer periphery of the plug housing 1 and the socket housing 10. This concave-convex fitting structure enables the irregularly shaped connecting ring 2 to firmly fasten the plug housing 1 and the socket housing 10 together, preventing axial separation.

[0044] Example 5 differs from Example 4 in that, as Figure 1As shown, as a specific assembly method, one end of the connecting nut 8 can be fixedly connected to the socket housing 10 by the screw 6 to ensure that they do not rotate or loosen during operation.

[0045] Example 6: The working principle and operation process of the locking structure of the present invention are as follows:

[0046] (a) Connector locking state

[0047] When the connector is in its normal locking state, the locking cylinder 4 is pushed to the left (towards the plug) by the spring force of the spring 5. At this time, the single key 41 on the inner side of the locking cylinder 4 is engaged in the strip guide groove 21 of the irregular connecting ring 2, and the left end of the locking cylinder 4 abuts against the outer ring platform of the irregular connecting ring 2. In this state, the locking cylinder 4, through the combined action of the single key 41 and the end abutment, presses the irregular connecting ring 2 firmly against the plug housing 1 and the socket housing 10, preventing the irregular connecting ring 2 from opening radially or moving axially, thus ensuring reliable locking between the plug housing 1 and the socket housing 10.

[0048] (II) Separation Operation Process

[0049] When it is necessary to disconnect the plug from the socket, the following steps should be taken:

[0050] Step 1: Position the locking cylinder 4 towards the socket housing 10 ( Figure 1 (Pushing to the right) At this time, the locking cylinder 4 moves to the right against the elastic force of the spring 5, and the single key 41 on the inner side of the locking cylinder 4 disengages from the strip guide groove 21 of the irregular connecting ring 2. As the locking cylinder 4 moves to the right, the irregular connecting ring 2 is gradually exposed.

[0051] Step 2: Continue pushing the locking cylinder 4 so that the key 41 enters the axial guide section of the irregular guide groove 81 of the connecting nut 8 and moves along the axial guide section to its rightmost end. Then rotate the locking cylinder 4 so that the key 41 enters the circumferential limiting section of the irregular guide groove 81. When the key 41 rotates to the position aligned with the axial locking section, release the locking cylinder 4. Under the elastic force of the spring 5, the locking cylinder 4 is pushed to the left to reset, and the key 41 moves to the left along the axial locking section in the opposite direction to its entry direction until it is blocked by the closed end. At this point, the key 41 is stuck at the end of the irregular guide groove 81, and the locking cylinder 4 is held in the retracted position separated from the irregular connecting ring 2.

[0052] Third step: Since the locking cylinder 4 has retracted, the irregular connecting ring 2 is fully exposed and no longer constrained, and the operator can easily remove the two-part irregular connecting ring 2 from the plug housing 1 and the socket housing 10.

[0053] Step 4: After removing the irregular connecting ring 2, the locking constraint between the plug housing 1 and the socket housing 10 is removed, and they can be directly separated.

[0054] (III) Locking Operation Process

[0055] When it is necessary to re-lock the plug and socket, the following steps should be taken:

[0056] Step 1: After inserting the plug housing 1 into the socket housing 10, the operator fastens the two-lobed irregular connecting ring 2 onto the grooves of the plug housing 1 and the socket housing 10.

[0057] Step 2: At this point, the locking cylinder 4 is still in the retracted state, meaning that the key 41 is stuck at the end of the axial locking section of the irregular guide groove 81. Slightly push the locking cylinder 4 towards the socket housing 10 to disengage the key 41 from the closed end of the axial locking section. Then rotate the locking cylinder 4 to allow the key 41 to re-enter the axial guide section from the axial locking section through the circumferential limiting section for easy disengagement.

[0058] Third step: When the single key 41 is aligned with the strip guide groove 21 of the irregular connecting ring 2, release the locking cylinder 4. Under the elastic force of the spring 5, the locking cylinder 4 is pushed to the left to reset, and the single key 41 moves to the left along the axial guide section and smoothly enters the strip guide groove 21 of the irregular connecting ring 2.

[0059] Fourth step: Under the action of spring 5, locking cylinder 4 continues to move to the left until its left end abuts against the outer ring platform of irregular connecting ring 2. At this time, key 41 engages with strip guide groove 21, locking cylinder 4 presses the irregular connecting ring 2 tightly, and connector returns to a reliable locking state.

[0060] Example 7: The present invention also provides a connector that adopts the quick-plug array connector locking structure described in the above embodiments.

[0061] Specifically, see Figure 5 As shown, the connector includes a plug housing 1 and a socket housing 10 that are interlocked as described in Embodiment 1, as well as a complete locking structure composed of components such as a shaped connecting ring 2, a spring 5, a locking cylinder 4, a connecting nut 8, and a socket sleeve 9. The specific composition, connection relationship, and locking principle of this locking structure have been described in detail in Embodiment 1 and will not be repeated here.

[0062] like Figure 5 As shown, as a further optimization of the connector, the connector also includes a plug sleeve 13 fitted over the outer end of the plug housing 1. Both the plug sleeve 13 and the aforementioned socket sleeve 9 are provided with a lanyard bracket 12 for securing a pull rope or similar operating component, facilitating long-distance insertion and removal operations in confined spaces. Simultaneously, both the plug sleeve 13 and the socket sleeve 9 are fitted with retaining sleeves 11, which are used to secure external oil pipes (not shown in the figure) to the plug sleeve 13 and the socket sleeve 9 respectively, thus forming a complete fluid connector assembly.

[0063] In a preferred embodiment, the connector described in this example is a hybrid optoelectronic connector, which internally assembles optical contacts and electrical contacts. The plug housing 1 and the socket housing 10 are equipped with insulating components, which are sealed to the housing components by two axial sealing rings. The optical and electrical contacts are sealed to the insulator by two to three axial sealing rings.

[0064] Example 8 differs from Example 7 in that the type of connector is different. The connector shown in Example 7 is a hybrid optoelectronic connector, internally equipped with optical and electrical contacts. In this example, the connector can be any one of an electrical connector, an optical connector, or a fluid connector. Regardless of the specific type of connector, a quick-release array connector locking structure as described in Example 1 is provided to achieve quick locking and disengagement between the plug and socket, achieving the same technical effect.

[0065] In summary, the quick-release array connector locking structure and connector provided by this invention, through the cooperation of the elastic locking component and the specially designed irregular guide groove 81 and strip guide groove, utilizes the elastic force of the spring 5 to achieve automatic reset and locking of the single key 41. This structure is simple to operate, requiring only three actions of "push-rotate-release" to complete the locking process, and effectively prevents disengagement after locking. It has the advantages of reliable connection, convenient operation, and compact structure.

[0066] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that any modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions of some or all of the technical features thereof, within the spirit and principles of the present invention, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
