Description

Technical Field

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

[0002] A connector is an electro-electronic device used to establish temporary or permanent electrical connections between circuits. It enables the smooth and efficient transmission of current or signals between devices. Connectors typically consist of a plug and a socket, which are connected by insertion or mating.

[0003] Meanwhile, to prevent accidental disconnection or detachment of the connector, a corresponding locking structure needs to be designed to ensure that the connector can maintain a stable and continuous contact state after connection, avoiding connection failure due to vibration, pulling, or other external forces. Locking mechanisms vary widely across different types of connectors, such as snap-fit, threaded, push-pull self-locking, and knob-type. Currently, most connectors with locking mechanisms require tools to unlock, which is inconvenient; or the locking structure is easily unlocked, resulting in poor reliability and even some danger; or, to achieve the locking function, multiple connecting components need to be designed, leading to complex structures, high costs, and higher requirements for the connector's sealing connection line.

The present invention connects the first locking component and the second locking component in the first locking structure to the first boss respectively, and guides the boss through the guide surface of the connecting section, so that the first connector and the connecting part can be quickly locked and unlocked without the aid of external tools, which is especially suitable for occasions where the connector needs to be frequently plugged and unlocked;

[0049] b. In this invention, the unlocking of the first connector and the connecting part requires the simultaneous control of the connecting part to move axially and rotate about the axis relative to the first connector while applying an external force to the connecting part relative to the first connector. Therefore, its locking function has high reliability and can avoid mis-locking due to vibration, shaking and misoperation.

[0050] c. The present invention ingeniously utilizes the connection relationship between the first connector, the second connector and the locking component to design a first locking structure that is convenient for locking and unlocking and a second locking structure that is very simple in structure. This not only enables reliable locking of the first connector and the second connector and convenient unlocking, but also reduces their production cost.

[0051] d. By concentrating the first locking component, the second locking component, the third locking component in the second locking structure, and the first rib, the second rib, and the third rib on the inner wall of the connecting part, the present invention not only improves the strength of the connecting part, but also greatly saves the space used for connection and locking, and effectively reduces the size of the connector while ensuring reliable locking and quick unlocking and disassembly.

[0052] e. This invention, by setting a first locking structure that combines easy unlocking and reliable connection, a third locking structure that requires tools to unlock, and a plug that facilitates connection with the connecting part, allows the connecting structure to meet the requirements of rapid installation and disassembly and reliable connection during debugging, thereby improving the efficiency of installation, debugging, and testing. After debugging is completed, the plug is removed, and the first and third locking structures ensure that the components of the connecting structure are reliably connected and will not separate due to vibration, shaking, or misoperation.

Detailed Implementation

[0066] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0067] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0068] In one embodiment of the present invention, a connection structure is provided, see [link to previous document]. Figures 1 to 3 It includes a first connector 1 and a connecting part 2. The connecting part 2 is sleeved on the outside of the first connector 1 and can rotate around the axis of the first connector 1. A first locking structure is provided between the first connector 1 and the connecting part 2.

[0069] The first locking structure includes a first boss 11 and a locking component that cooperates with the first boss 11; of the two components, the first boss 11 and the locking component, one component is fixedly connected to the first connector 1, and the other component is fixedly connected to the connector 2.

[0070] The locking component includes a first locking component 21 and a second locking component 22 disposed opposite to each other, wherein the first locking component 21 has a pressing portion that can move relative to the second locking component 22;

[0071] If the first locking structure is in the locked state, the first boss 11 is located between the second locking component 22 and the pressing part, and the pressing part abuts against the first boss 11, so that the first boss 11 abuts against the second locking component 22, and the axial relative position of the first connector 1 and the connector 2 is locked.

[0072] If the first locking structure is in the unlocked state, the first boss 11 is separated from the second locking component 22, and the axial relative positions of the first connector 1 and the connector 2 can be separated.

[0073] In this embodiment, the connection structure further includes a second connector 3, which is connected to the first connector 1. The connecting portion 2 is sleeved on the outside of the second connector 3 and is configured to rotate about the axis of the second connector 3. A second locking structure is also provided between the connecting portion 2 and the second connector 3, which is configured to lock the second connector 3 relative to the connecting portion 2 in a position away from the first connector 1.

[0074] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the connecting part 2 includes a first end face 251, a second end face 252, and a group of protruding ribs arranged radially along its inner wall. The group of protruding ribs includes a first protruding rib 241 and a second protruding rib 242.

[0075] The locking component is located inside the rib group, specifically between the first rib 241 and the second rib 242. The first locking component 21 includes a fixed end 211, a free end 212, and a connecting section 213. The fixed end 211 is fixedly connected to the first rib 241, and the connecting section 213 connects the fixed end 211 and the free end 212. The free end 212 is swayable relative to the fixed end 211 and constitutes the pressing part. The second locking component 22 is fixedly connected to the second rib 242.

[0076] Accordingly, the first boss 11 is disposed on the outer wall of the first connector 1. Preferably, a plurality of rib groups, i.e., a plurality of first ribs 241 and second ribs 242, are evenly distributed circumferentially on the inner wall of the connecting part 2, and a locking component is disposed between each group of first ribs 241 and second ribs 242. The plurality of locking components are evenly distributed on a virtual circumference with the axis of the connecting part 2 as the central axis; correspondingly, a plurality of first bosses 11 that cooperate with the locking components are disposed on the first connector 1. That is, there are a plurality of first locking structures, preferably three.

[0077] Preferably, the fixed end 211 is close to the first end face 251, the free end 212 is away from the first end face 251, and the connecting segment 213 has a guide surface 2131 on the side close to the first end face 251. The guide surface 2131 extends away from the first end face 251 in a direction away from the fixed end 211 and first approaches and then moves away from the second locking member 22. See also Figure 7 The guide surface 2131 includes a first segment in sequence in the extension direction away from the fixed end 211. f1 Second end face f2 The first end face f1 The distance between the second end face and the second locking member 22 decreases in the extending direction away from the fixed end 211. f2 The distance between the first boss 11 and the second locking member 22 increases in the extending direction away from the fixed end 211. When the first locking structure is in the locked state, the first boss 11 is abutted against the second end face. f2 Between the free end and the second locking component 22, due to the first end face f1 and the second end face f2 connection c1The distance to the second locking member 22 is minimized, meaning the first boss 11 is locked between the first locking member 21 and the second locking member 22 in a surrounded state, thus enabling reliable locking. More preferably, the connecting segment 213 also has a structure that widens in the direction near the free end 212, which increases the strength of the first locking member 21 and improves the service life of the first locking mechanism.

[0078] like Figure 3 As shown, the first boss 11 is disposed on the first connector 1, and has a third surface 111 and a fourth surface 112. The third surface 111 is parallel to the end face of the first connector 1. When the first connector 1 and the connecting part 2 are connected, the fourth surface 112 abuts against the guide surface 2131, and the extending direction of the fourth surface 112 corresponds to the extending direction of the guide surface 2131. This increases the contact area between the fourth surface 112 and the guide surface 2131 when they abut, which improves the reliability of the locking function and reduces stress concentration, thus extending the product's service life.

[0079] In this embodiment, when the relative position of the first connector 1 and the connecting part 2 is configured to switch from a locked state to an unlocked state or vice versa, the connecting part 2 is configured to rotate and move axially relative to the first connector 1. Specifically, when the first connector 1 and the connecting part 2 switch from an unlocked state to a locked state, the connecting part 2 moves axially toward the first connector 1 and simultaneously rotates about its axis, with the rotation direction being the direction that brings the first boss 11 toward the first locking member 21. When the first boss 11 presses against the guide surface 2131 and moves between the pressing part and the second locking part 22, it is locked by the mutual pressing of the second locking part 22 and the pressing part, thereby locking the relative position of the first connector 1 and the connecting part 2. Figure 6 As shown.

[0080] When the first connector 1 and the connecting part 2 switch from the locked state to the unlocked state, the first boss 11 is first controlled to press against the pressing part and move away from the first locking component 21, while the connecting part 2 is rotated at the same time to separate the first boss 11 from the first locking component 21, thereby realizing the separable state of the first connector 1 and the connecting part 2; and under the elastic force of the second locking component 22, the separation of the first connector 1 and the connecting part 2 can be accelerated. Based on the first locking structure described above, the present invention provides that the first connector 1 and the connecting part 2 can be quickly locked and unlocked without the need for external tools, which is especially suitable for occasions where connectors need to be frequently mated and unlocked, such as some testing fields where one connector needs to be frequently mated with multiple connectors. The connection structure provided by the present invention can effectively improve testing efficiency. Furthermore, the unlocking between the first connector 1 and the connecting part 2 provided by the present invention requires applying an external force to the connecting part 2 relative to the first connector 1 while simultaneously controlling the connecting part 2 to move axially and rotate about the axis relative to the first connector 1. Therefore, the locking structure has high reliability and can avoid mis-locking due to vibration, shaking, and misoperation, thus improving the security of the connection between the two.

[0081] In another embodiment of the present invention, the difference from the above embodiment lies in the extension direction of the guide surface 2131. In this embodiment, the guide surface 2131 extends away from the fixed end 211, then moves closer to the first end face 251, and then moves closer to the second locking member 22. In this embodiment, unlike the above embodiment where the first locking member 21 and the pressing part abut against the upper and lower sides of the first boss 11, in this embodiment, the first locking member 21 and the pressing part abut against the left and right sides of the first boss 11. Therefore, the reliability of the locking function between the first connector 1 and the connecting part 2 can be further improved.

[0082] In one embodiment of the present invention, the second locking structure includes a second boss 31 and a third locking component 23. The second boss 31 is disposed on the second connector 3, and the third locking component 23 is disposed on the connecting part 2. When the connecting part 2 and the second connector 3 are connected, the second boss 31 and the third locking component 23 are abutted together.

[0083] like Figure 3 As shown, one end of the third locking component 23 is disposed on the inner wall of the connecting portion 2, and the other end extends toward the center of the connecting portion 2. The third locking component 23 is preferably... Figure 2 The circular ring structure shown is arranged circumferentially along the inner wall of the connecting portion 2. In this embodiment, as... Figure 2As shown, the ends of the first rib 241 and the second rib 242 that are away from the first end face 251 are both fixedly connected to the third locking component 23.

[0084] like Figure 4 As shown, one end of the second protrusion 31 is fixedly connected to the outer wall of the second connector 3, and the other end extends outward from the second connector 3. Preferably, there are multiple second protrusions 31, which are evenly distributed on a virtual circumference with the axis of the second connector 3 as the central axis. In this embodiment, see... Figure 1 , Figure 2 and Figure 4 The lower end of the second connector 3 passes sequentially through the first end face 251 and the second end face 252 of the connecting part 2 until the second protrusion 31 abuts against the third locking member 23. Specifically, the first surface of the second protrusion 31 abuts against the second surface 231 of the third locking member 23. The first surface is the surface of the second protrusion 31 away from the first connector 1, i.e., away from the first end face 251, and the second surface 231 is the surface of the third locking member 23 near the first connector 1, i.e., near the first end face 251. The second protrusion 31 is disposed between two adjacent rib groups and can rotate axially between the two adjacent rib groups. Specifically, the second protrusion 31 is disposed between the first rib 241 in one rib group and the second rib 242 of another rib group adjacent to that rib group. Thus, the connecting part 2 and the second connector 3 can rotate relative to each other about their axial direction, but the second connector 3 is positioned relative to the connecting part 2 along the following path. Figure 1 and Figure 2 The downward axial direction shown is locked. Then, the first connector 1 and the second connector 3 are plugged into each other, and the relative position between the connecting part 2 and the first connector 1 is locked by the first locking mechanism, thereby realizing the locked connection of the first connector 1, the second connector 3 and the connecting part 2.

[0085] More preferably, a slot is provided between the first protruding rib 241 and the third locking component 23, the slot being configured to accommodate at least a portion of the second protrusion 31. This slot enables bidirectional axial locking of the second connector 3 relative to the connecting portion 2, further improving the reliability of the locking function of the connection structure. It should be noted that in this embodiment, the first protruding rib 241 also serves as an unlocking and positioning element; that is, when the second protrusion 31 rotates to abut against the first protruding rib 241, the second connector 3 and the connecting portion 2 can be separated, eliminating the need for repeated attempts to pull out the second connector 3, thus further improving the unlocking speed.

[0086] Furthermore, in one embodiment of the present invention, the connecting portion 2 further includes a third rib 243 arranged radially along its inner wall, the third rib 243 being disposed between two adjacent rib groups. In this embodiment, the second boss 31 is disposed between adjacent second ribs 242 and third ribs 243, or the second boss 31 is disposed between adjacent first ribs 241 and third ribs 243, thereby reducing the range of axial rotation of the second boss 31 relative to the connecting portion 2.

[0087] Of course, in another embodiment of the present invention, the third locking component 23 may not be a circular structure, but may be a plurality of locking platforms corresponding one-to-one with the second protrusion 31. In one embodiment of the present invention, see... Figure 1 and Figure 6 The connection structure further includes a housing 4, and the end of the second connector 3 away from the first connector 1 extends into the interior of the housing 4 and is threadedly connected to the housing 4. Figure 1 As shown, one end of the second connector 3 passes through the first end face 251 and the second end face 252 of the connector 2 until the boss 31 abuts against the third locking member 23 and then is connected to the housing 4 by a thread.

[0088] The connection structure provided by this invention cleverly utilizes the connection relationship between the first connector, the second connector, and the locking component to design a first locking structure that facilitates locking and unlocking, and a second locking structure with a very simple structure. The second locking structure restricts the second connector from moving away from the first connector. Figure 1 and Figure 5 As shown, the relative positions of the first connector and the locking component are locked by the first locking structure, thereby realizing the reliable locking function of the first connector and the second connector. The locking structure is reliable and will not separate due to vibration, misoperation, etc.

[0089] Furthermore, the connection structure provided by the present invention concentrates all the first locking component, the second locking component, the third locking component in the first locking structure, as well as the first protrusion 241, the second protrusion 242, and the third protrusion 243 on the inner wall of the connection part. This not only improves the strength of the connection part but also greatly saves the space used for connection and locking. While ensuring reliable locking and quick unlocking and disassembly, it effectively reduces the size of the connector. In addition, only a few protrusions need to be designed on both the first connector and the second connector, which can reduce the overall production cost of the connection structure.

[0090] In another embodiment of the present invention, a connection structure is provided that further includes a third locking structure in addition to the connection structure described above. See also Figures 8 to 10 The third locking structure is disposed between the first connector 1 and the connecting portion 2. The third locking structure includes a fourth locking component 12 and a fifth locking component 26, one of which is disposed on the first connector 1, and the other on the connecting portion 2. The fourth locking component 12 has an elastic component 121 capable of moving in the radial direction of the first connector 1 and / or the connecting portion 2. The fifth locking component 26 includes a receiving groove 261, preferably a through-hole structure. When the third locking structure is configured in a locked state, the elastic component 121 is disposed within the receiving groove 261, and the relative positions of the first connector 1 and the connecting portion 2 are locked. When the third locking structure is configured in an unlocked state, the elastic component 121 separates from the receiving groove 261, and the axial relative positions of the first connector 1 and the connecting portion 2 can be separated.

[0091] In one specific embodiment of the present invention, such as Figure 10 As shown, the fourth locking component 12 is disposed on the first connector 1, one end of which is fixedly connected to the first connector 1, and the other end of which is provided with the elastic component 121, the elastic component 121 having an outwardly extending protrusion. The fifth locking component 26 is disposed on the connecting portion 2, as shown. Figure 9 As shown, the fifth locking component 26 includes a receiving groove 261 disposed on the side wall of the connecting portion 2. When the third locking structure is configured in the locked state, the protrusion is engaged in the receiving groove 261; when the third locking structure is configured in the unlocked state, the protrusion abuts against the inner wall of the connecting portion 2. In this embodiment, in addition to locking their axial position through the first locking structure, the first connector 1 and the connecting portion 2 can also lock their relative position through the third locking structure. By doubly locking the relative position of the first connector 1 and the connecting portion 2 through the first locking structure and the third locking structure, the reliability of the locking between them can be further improved.

[0092] It should be noted that the first locking structure and the third locking structure provided by the present invention can be combined in various ways. One such combination is as follows: Figures 8 to 10As shown, two first locking structures and one third locking structure are provided between the first connector 1 and the connecting part 2. Preferably, these three locking structures are evenly distributed circumferentially. A second combination is to provide two first locking structures and two third locking structures between the first connector 1 and the connecting part 2. Preferably, these four locking structures are evenly distributed circumferentially, with two first locking structures and two third locking structures facing each other. A third combination is to provide three first locking structures and one to three third locking structures between the first connector 1 and the connecting part 2. The three first locking structures are as follows: Figure 2 and Figure 3 The third locking structure is evenly distributed along the circumference of the connecting structure. It is positioned between two of the first locking structures. One third locking structure can be positioned between two adjacent first locking structures in a given group, or one third locking structure can be positioned between each pair of adjacent first locking structures in every group. In this embodiment, the receiving groove 261 in the third locking structure is positioned between two adjacent groups of protruding ribs.

[0093] In one embodiment of the present invention, such as Figure 9 As shown, the connection structure further includes a blocking block 5, which is connected to the connecting portion 2. The blocking block 5 is configured to abut the elastic member 121 on the fourth locking member 12 away from the receiving groove 261, thereby enabling the third locking structure to be in an unlocked state. There are several ways to connect the blocking block 5 to the connecting portion 2. One method is as follows... Figure 11 As shown, the blocking block 5 also includes a clamp 52. The blocking block body is disposed inside the clamp 52. When the clamp is opened, the blocking block 5 faces the receiving groove 261. When the clamp is released, the blocking block 5 extends into the receiving groove 261 and presses against the elastic member 121, causing it to exit the receiving groove 261. In another embodiment, the blocking block 5 is threadedly connected to the connecting portion 2. For example, if the portion of the elastic member 121 that is engaged in the receiving groove 261 is cylindrical or nearly cylindrical, then the receiving groove 261 can be configured as a threaded hole, and the blocking block 5 can be a stud structure. Therefore, the present invention does not limit the specific structure of the elastic member 121, the receiving groove 261, and the blocking block 5; other reasonable embodiments also fall within the protection scope of the present invention.

[0094] Currently, the reliability of the locking function and the ease of unlocking in connection structures are often mutually exclusive. Especially in scenarios involving repeated debugging or testing, where the components of the connection structure need to be repeatedly disassembled and reassembled, and where high reliability of the connections between components is required after debugging or testing, ease of use is often sacrificed, leading to long debugging times and low testing efficiency. The connection structure provided by this invention features a first locking structure that balances ease of unlocking and connection reliability, a third locking structure requiring tools for unlocking, and a plug for easy connection to the connection part. By connecting the plug with the receiving groove, the connection structure can meet the requirements of rapid installation and disassembly as well as reliable connection during debugging, thereby improving the efficiency of installation, debugging, and testing. After debugging, the plug is removed, and the first and third locking structures ensure a highly reliable connection between the components of the connection structure, preventing separation due to vibration, shaking, or misoperation.

[0095] In one embodiment of the present invention, a connector is provided, including the connection structure as described above, wherein a first connector 1 in the connection structure is connected to a second connector 3; and a connection part 2 is sleeved on the outside of the first connector 1 and the second connector 3 and is respectively connected to the first connector 1 and the second connector 3.

[0096] In this configuration, the first connector 1 is either a male or female connector, and the second connector 3 is the other. The relative positions of the first connector 1 and the second connector 3 are locked or unlocked through the first locking structure and the second locking structure.

[0097] In one embodiment of the present invention, a third locking structure and a blocking block as described in any of the above embodiments are further provided between the first connector 1 and the second connector 3 in the connector. The first connector 1 and the connecting part 2 achieve locking and unlocking functions through the combination of the first locking structure and the third locking structure, and the blocking block can also be used to unlock the third locking structure, so that only the first locking structure is used to lock the first connector 1 and the connecting part 2.

[0098] In one embodiment of the present invention, a locking structure is provided, the locking structure including a first locking structure, the first locking structure including a first boss and a locking member cooperating with the first boss; of the first boss and the locking member, one member is disposed on a first connector and the other member is disposed on a second connector. The locking member includes a first locking member and a second locking member disposed opposite to each other, the first locking member having a pressing portion movable relative to the second locking member.

[0099] If the first locking structure is in the locked state, the first boss is located between the second locking component and the abutting part, and the abutting part abuts against the first boss, so that the first boss abuts against the second locking component, and the relative positions of the first connector and the second connector are locked. If the first locking structure is in the unlocked state, the first boss is separated from the second locking component, and the relative positions of the first connector and the second connector can be separated.

[0100] It should be noted that the first connector and the second connector can be the first connector 1 and the connector 2 described in the above embodiments, or they can be connectors of other structures. For example, the first connector is a sheet structure and the second connector is also a sheet structure. That is, the first boss in the first locking structure is disposed on the sixth surface of a sheet structure, and the locking component is disposed on the seventh surface of a sheet structure. When the sixth surface and the seventh surface are connected to each other and the first boss is engaged in the locking component, the two sheet structures can be locked.

[0101] In one embodiment of the present invention, the locking structure further includes a third locking structure, which comprises a fourth locking component and a fifth locking component. One of the fourth and fifth locking components is disposed on the first connector, and the other component is disposed on the second connector. The fourth locking component includes an elastic component configured to move in a direction perpendicular to the connection surface of the first and second connectors. The fifth locking component includes a receiving groove. When the third locking structure is configured in a locked state, the elastic component is disposed within the receiving groove, and the relative positions of the first and second connectors are locked. When the third locking structure is configured in an unlocked state, the elastic component separates from the receiving groove, and the relative positions of the first and second connectors can be separated.

[0102] It should be noted that the above-mentioned connector, locking structure embodiments and connection structure embodiments belong to the same inventive concept, and the entire contents of the connection structure embodiments are incorporated into the connector, locking structure embodiments by reference.

[0104] The above description is only a specific embodiment of this application.
