Description

Technical Field

[0001] The invention belongs to the field of electrical connectors, and in particular relates to a socket and a connector assembly. Background Art

[0002] Unmanned storage systems are gradually becoming the mainstream of storage systems, especially for certain dangerous goods, such as flammable and explosive materials. Unmanned storage systems can avoid the harm of dangerous goods to technicians, and can also avoid safety hazards caused by technical personnel's illegal operations. In the current unmanned storage system, technicians need to use unmanned transfer carts to realize the transfer of goods between transport vehicles and shelves. In this process, the unmanned transfer cart may face on-site conductive plug-in requirements such as plugging in power. However, due to the cumulative tolerances of the installation accuracy of the external plug, the installation accuracy of the external socket, and the parking position of the unmanned transfer cart, the external plug may have a large position deviation when blindly plugged with the external socket on site. Therefore, the external plug on the unmanned transfer cart and the external socket of the adapter device must have good blind plugging capabilities, that is, the external plug of the unmanned transfer cart and the external socket of the adapter device must have a large floating amount and blind plugging guide range.

[0003] The floating amount of existing electrical connectors is generally small, and blind plugging guidance is generally performed through guide holes and guide pins respectively arranged on the plug end and the socket end. A guide bevel is generally set on the edge of the end of the guide hole for the guide pin to be inserted. The maximum outer diameter of the tapered hole section surrounded by the guide bevel is the maximum blind plugging guidance range that the guide hole can provide. Therefore, the blind plugging guidance range of this hole pin guide structure is restricted by the aperture of the guide hole and cannot provide a larger blind plugging guidance range. If the blind plugging guidance range of the hole pin guide structure is to be increased, the diameter of the guide hole and the guide pin must be increased at the same time. This will cause the volume and self-weight of the electrical connector to increase accordingly, affecting the use while also increasing the cost. In order to achieve the corner alignment guidance of the electrical connector during insertion, the aforementioned guide holes and guide pins must be arranged in groups along the circumference of the electrical connector so that the plug and the socket can be straightened through multiple groups of guide holes and guide pins. This will inevitably further increase the occupied space and self-weight of the electrical connector. Therefore, the floating amount and blind plugging guide range of existing electrical connectors are relatively small. Increasing the floating amount and blind plugging guide range will cause the space occupied by the electrical connector to increase dramatically, making it unsuitable for the blind plugging scenario of the aforementioned unmanned transfer vehicle and adapter equipment.

DETAILED DESCRIPTION

[0037] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0038] The inventive concept of the socket of the present invention is as follows:

[0039] A socket, specifically comprising a socket housing. A floating mounting plate is provided on the socket housing, and a floating connection structure for fixed connection with an adapter device is floatingly provided on the floating mounting plate. The floating mounting plate can provide a sufficient area to set the floating connection structure for fixed connection with the adapter device, thereby ensuring that the socket housing has a sufficient floating amount relative to the adapter device. The plug-in end of the socket housing has a guiding bell mouth with the large end facing outward, so as to guide the socket housing to perform floating alignment in the radial direction when plugged in. The guiding bell mouth can provide a larger guiding range to guide the plug and the socket housing to align in the radial direction when plugged in. A corner straightening structure is provided on the side wall of the guiding bell mouth, and the corner straightening structure is used to cooperate with the guiding matching structure on the adapter plug to achieve the floating alignment of the corner of the socket housing.

[0040] The above structure guides the blind insertion of the socket and the plug through the guide bell mouth provided on the plugging end of the socket housing and the corner straightening structure provided on the side wall of the guide bell mouth. Thus, when increasing the blind insertion guide range, it is only necessary to increase the large end opening of the guide bell mouth, which has little impact on the main body of the socket and will not cause the volume of the socket to increase excessively. Therefore, the above structure can increase the blind insertion guide range while taking into account the miniaturization design of the socket, and can better overcome the position deviation between the plug and the socket during blind insertion without causing the volume of the socket to increase excessively.

[0041] Based on the above inventive concept, an embodiment of the socket of the present invention is as follows:

[0042] A socket 1, the structure of which can refer to Figure 1 , 9 As shown in FIG. 10 , the socket housing 2 and the socket body 3 are provided in the socket housing 2. The socket body 3 has a pin 28 for plugging into the socket 4 on the adapter plug 27 so as to be connected with the adapter plug 27. Figure 2 The adapter plug 27 is plugged in and electrically connected. The specific structure of the socket body 3 is an existing structure and will not be described here.

[0043] The socket housing 2 specifically includes a cylindrical main housing 5 and a floating mounting plate 6 extending radially outward along the main housing 5. One end of the main housing 5 is used as a plug-in end for the adapter plug 27 to be inserted. The floating mounting plate 6 is arranged on the outer side of the main housing 5, and it can be a circular plate or a rectangular plate. The specific geometric shape of the floating mounting plate 6 depends on the actual use needs, and it is not listed here one by one. In this embodiment, the floating mounting plate 6 adopts a rectangular plate, on which a floating connection structure 7 for floating connection with the adapter device is arranged, so that the socket housing 2 is floatingly mounted on the adapter device. The plug-in end of the socket housing 2 is provided with a guide bell mouth 8, which is a cylindrical structure in the shape of a cone, and its small end is connected to the plug-in end of the main housing 5, and the large end is axially outward. When plugged in, the plug-in end of the plug 27 first enters the large end of the guide bell mouth 8. At this time, if the socket 1 is not aligned with the plug 27 in the radial direction, the plug-in end of the plug 27 will be pressed against the inner wall of the guide bell mouth 8. Under the guidance of the guide bell mouth 8, the insertion force of the plug 27 can drive the socket housing 2 to move radially until the socket housing 2 moves to a position where the socket 1 and the plug 27 are aligned and can be plugged in. A corner alignment structure is provided on the side wall of the guide bell mouth 8, and the corner alignment structure is used to cooperate with the guide matching structure on the adapter plug 27 to achieve the floating alignment of the corner of the socket housing 2, so that the corresponding jack 4 and the pin 28 can be aligned for smooth plugging.

[0044] The key points of this embodiment can be found in Figure 1As shown, the corner straightening structure is specifically a guide groove 9 arranged on the side wall of the guide bell mouth 8. One end of the guide groove 9 extends to the edge of the large end of the guide bell mouth 8 and has a flared opening 10. Correspondingly, a guide pin 11 for guiding and cooperating with the guide groove 9 is arranged on the plug 27. When plugging in, the guide pin 11 on the plug 27 first enters the flared opening 10. At this time, if the corners of the plug 27 and the socket 1 are not aligned, the guide pin 11 will press against the inner wall of the flared opening 10 as the plug 27 is inserted. Under the guidance of the flared opening 10, the insertion force of the plug 27 can drive the socket housing 2 to rotate circumferentially until the socket housing 2 rotates to a position that is aligned with the corner of the plug 27 and can be plugged in. The existing hole pin guide structure for blind insertion guidance must be arranged in groups around the socket housing 2 when achieving corner alignment. Compared with this structure, the guide groove 9 arranged on the side wall of the guide bell mouth 8 is used as the corner straightening structure, which effectively utilizes the space on the socket housing 2, so there is no need to occupy too much extra space. At the same time, since the flared mouth 10 is arranged on the large end of the guide bell mouth 8, its opening is relatively large, which can provide a larger corner blind plug guiding range. Therefore, the above structure can achieve a wider range of corner blind plug guiding while ensuring the miniaturization of the socket 1. In order to ensure the guiding effect, the guide grooves 9 can be arranged in groups along the axial direction of the socket housing 2, such as specifically arranging two, three, four or even more. The grouped guide grooves 9 are preferably evenly distributed on the socket housing 2 along the circumferential direction. Of course, the guide groove 9 can also adopt a groove type with gradually converging groove width, that is, one end of the guide groove 9 extends to the edge of the large end of the guide bell mouth 8, and the other end extends inward along the axial direction. The groove width of the guide groove 9 gradually converges inward to achieve the purpose of corner guiding.

[0045] For reference Figure 3 , Fig.11As shown, the socket housing 2 also includes a flameproof straight barrel section 12 for tightly plugging and matching with the plug housing of the adapter plug 27, and the flameproof straight barrel section 12 is arranged behind the small end of the guide bell mouth 8. Specifically, in this embodiment, the flameproof straight barrel section 12 is part or all of the straight barrel section on the plug-in end of the socket housing 2. One end of the straight barrel section is directly or indirectly connected to the small end of the guide bell mouth 8. In order to make the socket structure compact and further reduce the occupied space, the flameproof straight barrel section 12 is preferably directly connected to the guide bell mouth 8. The barrel cavity can be tightly matched with the plug-in end of the plug 27, so that after the plug 27 is inserted, the matching gap between the flameproof straight barrel section 12 and the plug 27 can be minimized as much as possible, so as to prevent the electric sparks, arcs, etc. accidentally generated during the power-on process after the plug 27 and the socket 1 are plugged in place from escaping from the matching gap. In this way, the socket 1 can have good flameproof performance and can be used in operations in dangerous environments such as flammable and explosive environments. At the same time, since the guide groove 9 is arranged on the side wall of the guide bell mouth 8, the other end of the guide groove 9 relative to the flared mouth 10 does not exceed the junction of the guide bell mouth 8 and the flameproof straight tube section 12, that is, the flameproof straight tube section 12 and the guide bell mouth 8, guide groove 9, guide pin 11 and other guide structures are staggered in the axial direction (that is, the connector plug-in direction), so the arrangement of the aforementioned guide structure does not affect the flameproof effect of the flameproof straight tube section 12. In this way, on the one hand, it can ensure that the inner wall surface of the flameproof straight tube section 12 can be closely matched with the plug 27 at all places; on the other hand, it can also prevent the guide groove 9 from affecting and destroying the sealing of the flameproof straight tube section 12, so as to reduce the risk of the flameproof straight tube section 12 being broken down by current, thereby meeting the flameproof requirements.

[0046] For reference Figure 4 As shown, a floating hole 13 is provided on the floating mounting plate 6, and the aforementioned floating connection structure 7 specifically includes a floating sleeve 14 that is floatingly installed in the floating hole 13. In this embodiment, the floating hole 13 is provided at the four corners of the floating mounting plate 6 in the form of a rectangular plate, so that the floating hole 13 can be as large as possible. The floating sleeve 14 specifically includes a floating sleeve body 15 that is clearance-matched with the floating hole 13, and an anti-slip stop edge 16 provided at both ends of the floating sleeve body 15, and a floating gap is provided between the anti-slip stop edge 16 and the floating mounting plate 6. Such a setting has a reliable floating effect and is convenient for processing and assembly. When increasing the floating amount, it is only necessary to increase the aperture of the floating hole 13 or reduce the diameter of the floating sleeve body 15, so that it is easier to ensure a larger floating amount. In other embodiments, the floating connection structure 7 can also be a floating column provided on the floating mounting plate 6 and extending axially along the socket housing 2. The floating column is inserted into the adapter hole of the adapter device, and its end extends out of the adapter hole and is fixedly installed with a baffle for stopping with the hole edge of the adapter hole.

[0047] For reference Figure 4As shown, the floating sleeve 14 specifically includes a first sleeve body 17 and a second sleeve body 18. The first sleeve body 17 includes a first connecting tube 19 and a first stop edge 20, and the second sleeve body 18 includes a second connecting tube 21 and a second stop edge 22. The first connecting tube 19 and the second connecting tube 21 are axially removable and matched to form the aforementioned floating sleeve body 15. There is a gap between the first stop edge 20 and the second stop edge 22, and they are respectively stopped on both sides of the floating hole 13 to form the aforementioned anti-slip stop edge 16. The first connecting tube 19 and the second connecting tube 21 can be inserted into each other as a whole. At this time, the first sleeve body 17 can be inserted from the side of the second sleeve body 18 with the second stop edge 22, or from the other side, as long as there is enough gap between the first stop edge 20 and the second stop edge 22. The first connecting tube 19 and the second connecting tube 21 can also be axially abutted at the ends. At this time, fasteners can be installed at the axis of the two to relatively fix the first connecting tube 19 and the second connecting tube 21. This makes installation easy and allows for quick assembly and disassembly, thereby greatly reducing the assembly cost of the socket 1. In other embodiments, the floating sleeve 14 may specifically include a sleeve body and an annular baffle. The sleeve body includes a main body and a baffle disposed at one end of the main body. During installation, the main body of the sleeve body is first inserted into the floating hole 13, and then the annular baffle is fixed to the end of the main body extending out of the floating hole 13.

[0048] In order to further facilitate installation, an internal thread can be provided on the inner wall of one of the first connecting tube 19 and the second connecting tube 21, and an external thread can be provided on the outer wall of the other, so that the first connecting tube 19 and the second connecting tube 21 can be directly connected to each other through threads. Of course, the first connecting tube 19 and the second connecting tube 21 can also be connected to each other by interference fit. Furthermore, a mounting hole 23 can be provided on the one of the first connecting tube 19 and the second connecting tube 21 that has an external thread, so that the floating sleeve 14 can be directly fixed to the adapter device through fasteners or rivets, pins and other structures. This makes disassembly and assembly convenient and easy to implement. In this embodiment, an internal thread is provided on the first connecting tube 19, and an external thread is provided on the second connecting tube 21, and the mounting hole 23 is the barrel cavity of the second connecting tube 21.

[0049] Embodiments of the connector assembly of the present invention:

[0050] A connector assembly includes a socket 1 and a plug 27. The main body of the plug 27 is an existing structure, which can be referred to Figure 2As shown, a plug-in guide chamfer 24 and a guide pin are provided at the plug-in end. The guide pin 11 extends radially outward along the plug 27, and is provided on the plug 27 in a circumferential direction corresponding to the guide groove 9. The structure of the socket 1 can refer to the embodiment of the socket 1 described above, and will not be repeated here. The end of the pin 28 of the socket 1 has a pin section 26; the socket 4 on the plug 27 has a hole section 25, and the hole section 25 and the pin section 26 are plugged in and matched, so that there is an axial plug-in floating amount between the socket 1 and the plug 27. This can prevent the socket 1 and the plug 27 from being damaged during over-insertion on the one hand, and on the other hand, it also improves the flexibility of use of the socket 1 and the plug 27.

[0051] For the convenience of explanation, the connector assembly of the present invention is now described in detail in combination with a certain demand scenario. It should be emphasized that this demand scenario is only a specific example given for the convenience of explanation and does not have any special meaning.

[0052] It is now required that the socket 1 and the plug 27 have Figure 4 , Figure 5 The single-side radial floating amount δ, axial floating amount L, and single-side angular floating amount α are shown. Figure 6 As shown, the maximum diameter of the guide bell mouth 8 can be D2, and the outer diameter of the plug end of the plug 27 is d. In this way, when the plug 27 is plugged into the socket 1, it is necessary to ensure that δ≤(D2-d) / 2 to ensure that the guiding effect of the guide bell mouth 8 can fully cover the radial floating amount of the socket 1.

[0053] For reference Figure 8 As shown, let the maximum outer diameter of the large end of the guide bell mouth 8 be D1 and the maximum diameter be D2. Figure 7 As shown, the diameter of the guide pin 11 on the plug 27 is a, and the maximum opening width of the expansion 10 of the guide groove 9 is b. Figure 8 The geometric relationship shown in . Figure 8 The θ in the middle is the corner guiding range of the socket 1 under the current parameters, θ≥α, so as to ensure that the guiding effect of the flaring 10 can fully cover the corner floating amount of the socket 1.

[0054] Since the pin 28 is lengthened and the hole 4 is deepened, please refer to Fig. 9 As shown, when the distance between the contact end face of the plug 27 and the contact end face of the socket housing 2 is L, the contact length between the pin 28 and the socket 4 is sufficient to achieve a sufficient conductive connection. At this time, the pin 28 can be inserted forward a certain distance L1 (L1>0) to reach the predetermined fully plugged position. Fig.10As shown, the pin 28 is inserted forward a certain distance L2 (L2>0), at which time the abutting end surface of the plug 27 is pressed against the abutting end surface of the socket housing 2, and the pin 28 is still not pressed against the bottom of the hole 4. L=L1+L2, that is, the connector assembly has an axial floating amount L.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
