Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a retractable connector. Background Technology

[0002] With the rapid development of new energy vehicles, smart devices and other fields, various connectors, as key components for energy or signal transmission, are finding increasingly widespread applications. Taking the charging scenario of new energy vehicles as an example, when the charging gun of the charging pile is incompatible with the charging port of the vehicle, a conversion connector becomes a necessary accessory. This type of connector typically consists of a conductive wire, an input plug (compatible with the charging gun), and an output plug (compatible with the vehicle port), achieving electrical connection between the two ends through the conductive wire.

[0003] However, existing connectors suffer from messy conductive wire storage issues in practical use. To meet the needs of different scenarios, the conductive wires of connectors are usually designed to a certain length, but when not in use, the conductive wires lack an effective storage structure, easily becoming tangled and knotted. In addition, due to the loose wires and lack of a fixed plug, the wires easily snag on backpacks, tools, and other items during transport, and the overall bulky design occupies a large amount of space, causing great inconvenience to users when moving and carrying the device, especially in scenarios such as outdoor charging, seriously affecting the user experience. Therefore, a retractable connector is provided to solve the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a retractable connector to address the shortcomings of existing technologies, thereby solving the technical problem that existing connectors are inconvenient to store and carry.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A retractable connector includes a conductive wire, an input plug electrically connected to one end of the conductive wire, and an output plug electrically connected to the other end of the conductive wire. It also includes a storage frame for storing the conductive wire, and a storage base for fixing the input plug and the output plug is provided on the side of the storage frame. The storage frame has a storage chamber, in which a winding roller is rotatably mounted. The conductive wire passes through the winding roller, and the length of the conductive wire is perpendicular to the axis of rotation of the winding roller. The top of the storage base has an upper slot for inserting an input plug, and the bottom of the storage base has a lower slot for inserting an output plug.

[0006] Furthermore, both ends of the winding roller are coaxially provided with a rotating shaft that is rotatably connected to the storage frame. The ends of each rotating shaft away from the winding roller extend to the outside of the storage frame, and a knob is provided on the ends of the rotating shafts that extend to the outside of the storage frame.

[0007] Furthermore, both the inner walls of the upper and lower slots are provided with silicone limiting rings, and both the input and output plugs are formed with annular grooves for the silicone limiting rings to be inserted.

[0008] Furthermore, the storage base is detachably mounted on the storage frame.

[0009] Furthermore, the storage base is fixedly provided with a left splicing plate and a right splicing plate that are spaced apart and symmetrically arranged. The sides of the left and right splicing plates that are close to each other are formed with splicing grooves, and the sides of the storage frame that are far from each other are provided with splicing blocks for embedding into the splicing grooves.

[0010] Furthermore, each splicing slot is equipped with a second magnetic component at one end near the storage base, and each splicing block is equipped with a first magnetic component at its end for attracting the second magnetic component, with each first magnetic component placed on the same side.

[0011] Furthermore, each splicing groove has a guide bevel formed at the end away from the second magnetic component to guide the splicing block.

[0012] Furthermore, both the left and right splicing plates are formed with clearance grooves to accommodate the rotating shaft.

[0013] Furthermore, the storage frame is equipped with a clamping part for clamping and limiting the winding roller.

[0014] Furthermore, the clamping part includes a plurality of slots formed on the end face of the winding roller, the plurality of slots being arranged in an equidistant array around the axis of the rotating shaft; it also includes a sliding groove formed in the housing frame, a slider being slidably disposed in the sliding groove, the sliding direction of the slider being parallel to the axis of the rotating shaft, the slider being provided with a snap-fit ​​member for snapping into the slot, the end of the snap-fit ​​member near the winding roller being hemispherical, and the end extending into the housing cavity; a spring being provided in the sliding groove for applying a thrust toward the winding roller to the slider.

[0015] The beneficial effects of this invention are as follows: When storage is required, first insert the input plug into the upper slot and the output plug into the lower slot to fix them to the storage base. Then, rotate the winding roller, and the conductive wire gradually winds around the outside of the roller. The wound conductive wire is then placed in the storage chamber, thus achieving the storage of the conductive wire. When this connector is not in use, the above operations achieve the storage of the input and output plugs, as well as the conductive wire. This connector is easy to store and carry, improving the user experience. Attached Figure Description

Detailed Implementation

[0024] The following is a detailed description of a retractable connector according to the present invention, with reference to the accompanying drawings.

[0025] like Figure 1 As shown, an embodiment of the retractable connector of this utility model includes a conductive wire 1, an input plug 2 electrically connected to one end of the conductive wire 1, and an output plug 3 electrically connected to the other end of the conductive wire 1. This connector is a conversion connector for charging. When the charging port model on the new energy vehicle is incompatible with the charging gun model on the charging pile, the input plug 2 is first plugged into the charging gun on the charging pile, and then the corresponding output plug 3 is plugged into the charging port on the new energy vehicle, so that the charging gun can be connected to the charging port for charging, thus realizing the conversion connection for charging.

[0026] When not in use, for easy storage and carrying, this connector also includes a storage frame 4 for storing the conductive wire 1. The storage frame 4 has storage bases 5 on its sides for securing the input plug 2 and the output plug 3. First, insert and secure the input plug 2 to the top of the storage base 5, then insert and secure the output plug 3 to the bottom of the storage base 5, and finally store the conductive wire 1 inside the storage frame 4. This completes the storage of the connector (e.g., ...). Figure 7As shown in the image, the specific storage method will be detailed below.

[0027] like Figure 2-4 As shown, the storage frame 4 has a storage chamber 41, and a winding roller 42 is rotatably mounted inside the storage chamber 41. The conductive wire 1 passes through the winding roller 42, and the length direction of the conductive wire 1 is perpendicular to the axis of rotation of the winding roller 42. After rotating the winding roller 42, the conductive wire 1 gradually winds around the outside of the winding roller 42, and the wound conductive wire 1 is placed inside the storage chamber 41, thereby realizing the storage of the conductive wire 1. In order to rotate the winding roller 42, both ends of the winding roller 42 are coaxially provided with a rotating shaft 43 that is rotatably connected to the storage frame 4. The end of each rotating shaft 43 away from the winding roller 42 extends to the outside of the storage frame 4, and a knob 44 is provided on the end of the rotating shaft 43 that extends to the outside of the storage frame 4. By rotating the knob 44, the user can rotate the winding roller 42 together to realize the storage of the conductive wire 1.

[0028] In this embodiment, the top of the storage base 5 is formed with an upper slot 51 for inserting the input plug 2, and the bottom of the storage base 5 is formed with a lower slot 52 for inserting the output plug 3. Silicone retaining rings 53 are provided on the inner walls of both the upper slot 51 and the lower slot 52. Both the input plug 2 and the output plug 3 have annular grooves 6 for the silicone retaining rings 53 to engage with. The silicone retaining rings 53 are soft, deformable silicone parts. When the input plug 2 is inserted into the upper slot 51, the silicone retaining ring 53 in the upper slot 51 automatically engages with the annular groove 6 on the input plug 2. When the output plug 3 is inserted into the lower slot 52, the silicone retaining ring 53 in the lower slot 52 automatically engages with the annular groove 6 on the output plug 3. Through the cooperation of the silicone retaining rings 53 and the annular grooves 6, the input plug 2 and the output plug 3 can be stably fixed to the storage base 5 without applying force, thus achieving the storage of the input plug 2 and the output plug 3.

[0029] To prevent interference with the use of the storage base 5 when using this connector, the storage base 5 is detachably installed on the storage frame 4. Specifically, the storage base 5 has a left splicing plate 54 and a right splicing plate 55 fixedly arranged at intervals and symmetrically on its side. The sides of the left and right splicing plates 54 and 55 that are close to each other are formed with splicing grooves 56. The sides of the storage frame 4 that are far from each other are provided with splicing blocks 45 for embedding into the splicing grooves 56. After aligning the splicing grooves 56 with the splicing blocks 45, force is applied to the storage base 5, so that the different splicing blocks 45 are embedded into the corresponding splicing grooves 56. At the same time, the storage frame 4 is placed between the left and right splicing plates 54 and 55, realizing the splicing of the storage base 5 and the storage frame 4.

[0030] To improve the stability of the storage base 5 and the storage frame 4 after assembly, a second magnetic element 57 is installed at the end of each splicing slot 56 near the storage base 5, and a first magnetic element 46 is installed at the end of each splicing block 45 to attract the second magnetic element 57. All first magnetic elements 46 are placed on the same side. Both the first magnetic element 46 and the second magnetic element 57 are magnets. When different splicing blocks 45 are embedded into the corresponding splicing slots 56, the first magnetic element 46 and the second magnetic element 57 attract each other. Without applying force to the storage base 5, the storage base 5 and the storage frame 4 will not separate.

[0031] Each splicing slot 56 has a guide bevel 58 formed at the end furthest from the second magnetic member 57 to guide the splicing block 45. By setting the guide bevel 58, the splicing block 45 can be more accurately embedded into the splicing slot 56, improving the convenience of splicing.

[0032] The splicing blocks 45 on both sides are arranged to the left and right, and the knobs 44 on both sides are also arranged to the left and right. Both the left splicing plate 54 and the right splicing plate 55 are formed with relief grooves 59 to accommodate the rotating shaft 43. After the storage base 5 is spliced ​​with the storage frame 4, the rotating shaft 43 is placed in the relief groove 59, and the knob 44 is placed on the side of the left splicing plate 54 and the right splicing plate 55 that are far apart from each other. By setting the relief groove 59, the knob 44 can be rotated even after the storage base 5 is spliced ​​with the storage frame 4.

[0033] like Figure 5-6 As shown, the storage frame 4 is equipped with a clamping part for locking and limiting the winding roller 42. By setting the clamping part, the winding roller 42 before and after storage can be limited to prevent the winding roller 42 from automatically rotating and releasing the conductive wire 1. The clamping part includes a plurality of slots 47 formed on the end face of the winding roller 42, and the plurality of slots 47 are arranged in an equidistant array around the axis of the rotating shaft 43. It also includes a sliding groove 48 formed in the storage frame 4, and a slider 49 is slidably disposed in the sliding groove 48. The sliding direction of the slider 49 is parallel to the axis of the rotating shaft 43. The slider 49 is provided with a snap-fit ​​member 410 for snapping into the slot 47. The end of the snap-fit ​​member 410 near the winding roller 42 is hemispherical and extends into the storage chamber 41. A spring 411 is provided in the sliding groove 48 for applying a pushing force to the slider 49 in the direction of the winding roller 42.

[0034] When the conductive wire 1 is not wound and stored, the hemispherical end of the locking member 410 is engaged in one of the slots 47. When the winding roller 42 is rotated, the hemispherical end of the locking member 410 disengages from the slot 47 and slides on the end surface of the winding roller 42. At this time, the spring 411 is in a compressed state. When the conductive wire 1 is wound and stored, the hemispherical end of the locking member 410 is aligned with the corresponding slot 47. Under the action of the compressed spring 411, the hemispherical end of the locking member 410 is engaged in the slot 47. Under the action of the locking member 410 and the slot 47, the winding roller 42 is limited, which improves the stability of the conductive wire 1 after storage.

[0035] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0036] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
