Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a floating plug and a floating connector. Background Art

[0002] Connectors are used in many electrical connection products. For example, when two groups of batteries are connected in series, a bridge is formed through the connector. Common connectors are divided into a base and a connector. The base is often fixed at a specified position and electrically connected to the power source. The connector can move with the corresponding product and realize electrical conduction of the product through the connection between the connector and the base.

[0003] Taking multiple battery groups connected in series as an example, the base is installed on the battery pack, and connectors are connected at both ends of the conductive metal wire. When the two connectors are connected to the positive and negative electrodes of the two battery groups, the two battery groups are connected in series. Since the base is fixed on the battery pack and cannot be moved, the two connectors must be accurately inserted into the base. However, in actual operation, there are errors in the production and assembly of each component. Even if the error is within the range, it is very easy for the two connectors to not be fully inserted into the two bases, which will cause the connectors to be scrapped, increase the company's production costs and reduce assembly efficiency.

[0058] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0059] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] like Figure 1-Figure 5 As shown, Figure 1 It is a three-dimensional structural schematic diagram of a floating plug; Figure 2 is a cross-sectional view of a floating plug; Figure 3 This is the disassembled structure diagram of the floating plug; Figure 4 It is a schematic diagram of the three-dimensional structure of the plug housing 1; Figure 5 The floating plug of the present application includes a plug shell 1, a wire ear 2, a conductive body 3, a first contact body 4 and a second contact body 5. The wire ear 2 is movably arranged in the plug shell 1, the conductive body 3 is also located in the plug shell 1, and the conductive body 3 passes through the wire ear 2. The first contact body 4 is arranged between the wire ear 2 and the conductive body 3. At the same time, the two sides of the first contact are in contact with the wire ear 2 and the conductive body 3 respectively, and the second contact body 5 is arranged at the end of the conductive body 3 away from the wire ear 2. In specific applications, the wire ear 2 can drive the first contact body 4 to move relative to the conductive body 3 to achieve a small range of displacement of the wire ear 2.

[0061] The plug shell 1 has a through hole 11, a first channel 12 and a second channel 13. The through hole 11 is opened on the upper surface of the plug shell 1, the first channel 12 is opened in the plug shell 1 along the horizontal direction, and the second channel 13 is opened in the plug shell 1 along the vertical direction. The through hole 11, the first channel 12 and the second channel 13 are connected; the wire ear 2 is located in the first channel 12, and one end of the wire ear 2 is located at the intersection of the through hole 11, the first channel 12 and the second channel 13, and the other end of the wire ear 2 extends to the outside of the plug shell 1; the conductive body 3 is located in the second channel 13. In this embodiment, the first channel 12 and the second channel 13 are distributed at right angles.

[0062] In specific applications, there is a pit 22 at one end of the wire ear 2, and the first contact body 4 and the conductive body 3 are both located in the pit 22. There is a spacing L between the outer wall of one end of the conductive body 3 and the wall of the pit 22, and the spacing L is the displacement of the wire ear 2 relative to the conductive body 3. For example, when the spacing L is 10 mm, it means that the wire ear 2 can extend 10 mm more relative to the plug shell 1, or retract 10 mm into the plug shell 1. In addition, no matter whether the wire ear 2 is extended or retracted, the first contact body 4 keeps in contact with the conductive body 3 during the movement of the wire ear 2.

[0063] Specifically, a receiving hole 31 is provided in the middle of the conductive body 3, and the second contact body 5 is located in the receiving hole 31. Furthermore, the floating plug also includes an anti-touch rod 20, which is also arranged in the receiving hole 31. Specifically, the anti-touch rod 20 is located in the middle of the receiving hole 31. The anti-touch rod 20 is made of an insulating material. At the same time, the anti-touch rod 20 has a deformable property, and the anti-touch rod 20 is fixed by squeezing the anti-touch rod 20 into the receiving hole 31, such as a silicone material. The provision of the anti-touch rod 20 is conducive to preventing a person's finger from being accidentally inserted into the receiving hole 31, thereby reducing safety hazards.

[0064] Refer to Figure 6 and Figure 7 As shown, Figure 6 It is a partial structural cross-sectional view of the first contact body 4; Figure 7It is a schematic diagram of the three-dimensional structure of the first contact body 4. The first contact body 4 includes a support ring 41 and a plurality of guide bars 42. The support ring 41 is located on the surface of the wire ear 2. The plurality of guide bars 42 are spaced apart in the support ring 41. One end of the conductive body 3 abuts against the plurality of guide bars 42. Furthermore, the plurality of guide bars 42 are arranged obliquely in the same direction, that is, the guide bars 42 and the support ring 41 are not arranged vertically. There is an angle between the tangents of the guide bars 42 and the support ring 41. The angle is an obtuse angle. By means of oblique distribution, the length of the entire guide bar 42 can be effectively increased, which saves effort when assembling the conductive body 3. Furthermore, the guide bar 42 also has a first arc surface 421 and a second arc surface 422. The first arc surface 421 is arranged in a direction close to the conductive body 3, and the second arc surface 422 is arranged in the opposite direction of the first arc surface 421, that is, the second arc surface 422 extends in a direction close to the surface of the wire ear 2; when in use, the first arc surface 421 abuts against the conductive body 3, and the second arc surface 422 abuts against the surface of the wire ear 2. Preferably, the first contact body 4 also includes a limit strip 43, which is arranged in the support ring 41, and the limit strip 43 is arranged in the same manner as the guide strip 42; in specific application, one side of the limit strip 43 is located on the surface of the wire ear 2, the distance between the first arc surface 421 and the limit strip 43 is S, and the distance between the second arc surface 422 and the surface of the wire ear 2 is D, wherein D<S, so that when the conductive body 3 applies a longitudinal force, the travel limit of the guide strip 42 under the force is S, and after the guide strip 42 reaches this limit, the conductive body 3 abuts against the upper surface of the limit strip 43, and the guide strip 42 will not continue to move downward, thereby preventing the conductive body 3 from applying excessive force on the guide strip 42 and causing damage to the guide strip 42. In addition, since the D value is smaller than the S value, the second arc surface 422 first contacts the surface of the wire ear 2 during the downward pressing of the guide bar 42, and then the guide bar 42 will be further pressed downward. During this process, the second arc surface 422 will increase the pressure on the surface of the wire ear 2, increase the positive force on the side wall, and thus help reduce the temperature rise generated during subsequent use. Preferably, the outer surface of the support ring 41 is also provided with a tooth pattern 411, and the tooth pattern 411 contacts the wire ear 2. Through the provision of the tooth pattern 411, the contact area between the outer surface of the support ring 41 and the wire ear 2 is reduced, the resistance of the support ring 41 assembly is reduced, and the efficiency of the assembly and disassembly of the support ring 41 is improved.

[0065] Refer to Figure 8 and Fig. 9 As shown, Figure 8 is a schematic diagram of the three-dimensional structure of the second contact body 5; Fig. 9 : is a front view of the second contact body 5. The second contact body 5 includes a first contact area 51, a plurality of connecting strips 52 and a second contact area 53, one end of the connecting strip 52 is connected to the first contact area 51, and the other end of the connecting strip 52 is connected to the second contact area 53, the first contact area 51 and the second contact area 53 are arranged opposite to each other, and the plurality of connecting strips 52 are distributed between the first contact area 51 and the second contact area 53 at intervals.

[0066] Among them, the end area of ​​the connecting strip 52 close to the first contact area 51 is provided with a first protrusion 521, the first protrusion 521 protrudes outward, and the first protrusion 521 abuts against the wall surface of the connecting tube. It should be noted that the cross-sections of the first contact area 51 and the second contact area 53 in this embodiment are circular, so the inside of the circle is set as the inside, and the outside of the circle is set as the outside. Further, the end of the connecting strip 52 close to the second contact area 53 is provided with a second protrusion 522, similarly, the second protrusion 522 also protrudes outward, and the second protrusion 522 also abuts against the inner wall surface of the connecting tube; when the pin is inserted, the pin gives the first contact part an outward expansion force, causing the first contact part to deform, and synchronously, it will drive multiple first protrusions 521 to expand outward. When the pin is inserted to the end, the second protrusion 522 is also expanded outward.

[0067] In specific applications, there is an angle at the connection between the multiple connecting strips 52 and the first contact area 51 and / or the second contact area 53. The angle in this embodiment is an acute angle, that is, the multiple connecting strips 52 are distributed between the first contact area 51 and the second contact area 53 at inclined intervals.

[0068] Furthermore, the floating plug further includes a collar 50 , which is sleeved on an end of the conductive body 3 away from the first contact body 4 , and the second contact body 5 is fixed in the accommodating hole 31 through the collar 50 .

[0069] Please review Figure 1 and Figure 2 The floating plug also includes a first cover body 6 and a second cover body 7. The first cover body 6 is sleeved on the outer surface of the plug shell 1 along the direction of the second channel 13, and the second cover body 7 is sleeved on the outer surface of the plug shell 1 along the direction of the first channel 12. The first cover body 6 and the second cover body 7 cover the entire outer surface of the plug shell 1. At the same time, the first cover body 6 and the second cover body 7 are both made of insulating materials, which play a protective and insulating role for the floating plug. A copper bar is also connected to the surface of the wire ear 2, and the copper bar passes through the second cover body 7. In this embodiment, the first cover body 6 and the second cover body 7 are connected to the plug shell 1 in a snap-fit ​​manner, which can not only prevent the first cover body 6 and the second cover body 7 from falling off easily, but also improve the assembly efficiency and facilitate later disassembly. Furthermore, a limit block 61 is provided inside the first cover body 6, and a limit groove 21 is opened at the edge of the wire ear 2. When the first cover body 6 is inserted, the limit block 61 is located in the limit groove 21. The width of the limit groove 21 is greater than the width of the limit block 61, that is, the limit position of the movement of the wire ear 2 is limited by the limit block 61. For example, after the wire ear 2 moves a certain distance toward the outside of the plug shell 1, the inner wall of the limit groove 21 abuts against the limit block 61, and the wire ear 2 will not be able to continue to move outward; conversely, after the wire ear 2 retracts a certain distance into the plug shell 1, the other inner wall of the limit groove 21 abuts against the limit block 61, and the wire ear 2 will not be able to continue to retract inward.

[0070] Furthermore, the first contact body 4 can be one or two. When there are two first contact bodies 4, the two first contact bodies 4 are respectively located on the upper and lower sides of the end of the conductive body 3; specifically, the end of the conductive body 3 has a contact platform 32 extending outward, one side of the contact platform 32 abuts against one of the first contact bodies 4, and the other side of the contact platform 32 abuts against the other first contact body 4; in addition, the floating plug also includes a top cover 8, the top cover 8 is clamped at the port of the pit 22, and one side of the end cover abuts against the first contact body 4, squeezing the first contact body 4 toward one side of the contact platform 32.

[0071] like Figure 2 and Fig.10 As shown, Fig.10 It is a three-dimensional structural diagram of the fixing sleeve 9. The floating plug also includes a fixing sleeve 9, which is located in the first channel 12 and is clamped on the plug shell 1. The wire ear 2 passes through the fixing sleeve 9, and the fixing sleeve 9 restricts the wire ear 2 from moving in the left and right directions, so that the wire ear 2 mainly moves along the opening direction of the first channel 12. Further, the floating plug also includes a sleeve 10, which is spliced ​​with the plug shell 1 along the direction of the first channel 12, and is fixed by the second cover 7. The connection between the wire ear 2 and the copper busbar is located in the sleeve 10, and the copper busbar passes through the sleeve 10.

[0072] Furthermore, the floating plug further includes a plurality of sealing rings 60, wherein the plurality of sealing rings 60 are arranged at the connection between different components to play a sealing effect, preventing liquid or other impurities from entering the plug housing 1 and causing damage to the floating plug. For example, a sealing ring 60 is provided at the connection between the first cover 6 and the plug housing 1; a sealing ring 60 is provided at the connection between the second cover 7 and the plug housing 1; and a sealing ring 60 is provided between the sleeve 10 and the bottom wall of the second cover 7.

[0073] In summary, through the relative movement setting of the wire ear 2 and the conductive body 3, during use, the wire ear 2 can be moved along the direction of the first channel 12 to achieve a small range of change in the connection distance to solve the tolerance caused by assembly or production, without affecting the normal use of the floating plug and without the need to scrap it, which not only improves the assembly efficiency but also greatly reduces the production cost.

It should be noted that the second contact body 5 in this embodiment is an integrally formed structure, the upper part of which is the first contact area 51, the middle part is provided with the third contact area 54 at intervals, and the lower part is the second contact area 53. In addition, a plurality of connecting strips 52 are arranged in each third contact area 54, and the connecting strips 52 are arranged obliquely.

[0078] Further explanation, as shown in the figure, the first contact area 51 is also provided with an outwardly turned protrusion 55, which is used to fix the entire second contact body 5 and improve the stability of the second contact body 5. Of course, it can also be omitted according to needs, which is only one of the optional methods here and is not specifically limited.

[0079] Embodiment 4

[0080] like Fig.15 and Fig.16 As shown, Fig.15 is another cross-sectional view of the floating plug; Fig.16 : is a schematic diagram of another three-dimensional structure of a fixing sleeve 9. The difference between this embodiment and the first, second or third embodiments is that: the area of ​​the wire ear 2 away from the conductive body 3 is columnar, so as to facilitate the insertion of the cable; the fixing sleeve 9 is arranged at the end of the first channel 12 of the plug shell 1, and the wire ear 2 passes through the fixing sleeve 9; one end of the sleeve 10 abuts against the fixing sleeve 9, and the other end of the sleeve 10 abuts against the sealing ring 60.

[0081] Embodiment 5

[0082] like Figure 17-Figure 19 As shown, Fig.17 is a schematic diagram of the three-dimensional structure of the floating connector; Fig.18 is a cross-sectional view of a floating connector; Fig.19 It is a cross-sectional schematic diagram of the seat body 301. The floating connector of the present application comprises a floating plug and a socket 30, and the floating plug can be snap-connected with the socket 30. The floating plug in this embodiment adopts the structure of the first embodiment, the second embodiment, the third embodiment or the fourth embodiment.

[0083] The socket 30 includes a base body 301 and a conductor 302. The base body 301 has an insertion hole 3011. The plug shell 1 is inserted into the insertion hole 3011. The second channel 13 of the plug shell 1 is located in the insertion hole 3011. The conductor 302 is located in the middle of the insertion hole 3011. After the plug shell 1 is inserted, the conductor 302 is inserted into the accommodating hole 31, and the conductor 302 abuts against the second contact body 5, and the anti-touch rod 20 is correspondingly inserted into the conductor 302.

[0084] Furthermore, a retractable wall 3012 is provided in the plug-in hole 3011 of the seat body 301, and correspondingly, a convex ring 3021 is provided on the outer surface of the conductor 302. When the conductor 302 is inserted into the plug-in hole 3011 of the seat body 301, the conductor 302 will expand the retractable wall 3012. After the conductor 302 is inserted to the specified position, the end of the retractable wall 3012 will abut against the convex ring 3021, thereby fixing the conductor 302.

[0085] Furthermore, the floating connector also includes a lock body 40, which is movably arranged on the floating plug. A card slot 3013 is also provided on the outer surface of the seat body 301. When the floating plug is connected to the seat body 301, the lock body 40 is inserted into the card slot 3013, so that the floating plug and the seat body 301 will not be easily separated; when disassembly is required, the lock body 40 is pushed out of the card slot 3013 to separate the floating plug and the seat body 301.

[0086] In order to prevent people from accidentally touching the conductor 302, the floating connector further includes an anti-touch cap 70, which is clamped on the end of the conductor 302. Specifically, the anti-touch cap 70 is made of insulating material.

[0087] Taking the application to a battery pack as an example, when in use, the seat 301 is fixed on the battery shell, the conductor 302 is connected to the positive or negative electrode of the battery, and the current passes through the conductor 302 to the second contact body 5. The second contact body 5 guides the current to the conductor 3, and the conductor 3 guides the current to the wire ear 2 through the first contact body 4. Finally, the wire ear 2 guides the current to the copper bus or cable, thereby realizing the current extraction.

[0088] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
