[0002] A data cable is a cable used to connect electronic devices (such as mobile phones, tablets, computers, etc.) to a power adapter or computer interface to enable charging and data transmission. It is also frequently used as a charging cable in portable power banks.

[0003] Currently, data cable connectors are typically manufactured using a full injection molding process, which encapsulates the connector. However, data cable connectors are subjected to frequent insertion and removal forces during use. This full injection molding process cannot mold engineering materials with high hardness, strength, and wear resistance, making it prone to issues such as the connector separating from the injection-molded coating and breaking. Utility Model Content

[0004] This utility model provides a data cable and a power bank to solve the problem that in the prior art, when using a full injection molding process, the terminals of the connecting terminals are prone to separation from the injection molding and breakage.

[0005] This utility model discloses a data cable, which includes a connector, a rigid housing, and an adhesive coating structure. The connector includes a circuit board and a metal shell, which are fixedly connected. The rigid housing has an inner cavity and is fitted over the connector. One end of the metal shell extends out of the rigid housing and is fixedly connected to it. Inside the rigid housing, there is a gap between the circuit board and the inner cavity wall of the rigid housing. The rigid housing has an adhesive passage hole connecting the inner cavity to the outside. The adhesive coating structure includes an outer adhesive layer covering the rigid housing, an inner adhesive layer filling the gap between the circuit board and the inner cavity wall of the rigid housing, and a connecting adhesive layer located within the adhesive passage hole to connect the outer adhesive layer and the inner adhesive layer. The outer adhesive layer, the inner adhesive layer, and the connecting adhesive layer are integrally formed.

[0006] Optionally, one end of the rigid casing has a positioning window that matches the outline of the metal casing, and the metal casing passes through the positioning window and is tightly connected to the positioning window.

[0007] Optionally, at the end near the positioning window, the two opposite side walls of the inner cavity of the rigid housing are provided with first positioning ribs, and the two sides of the circuit board abut against the corresponding first positioning ribs.

[0008] Optionally, the connector includes an inner connecting adhesive layer, which is located between the circuit board and the metal housing, and is connected to both the circuit board and the metal housing.

[0009] Optionally, at one end near the positioning window, a second positioning rib is provided on both sides of the rigid casing perpendicular to the thickness direction, and the second positioning rib is squeezed tightly to both sides of the inner connecting rubber layer.

[0010] Optionally, a positioning protrusion is provided on the sidewall of the rigid casing perpendicular to the thickness direction, and the positioning protrusion is engaged with the end of the circuit board away from the metal casing; or

[0011] A positioning protrusion is provided on the side wall of the rigid casing perpendicular to the thickness direction. A side adhesive layer is provided on the side of the circuit board corresponding to the positioning protrusion. The positioning protrusion and the side adhesive layer are locked together at the end away from the metal casing.

[0012] Optionally, a positioning protrusion is provided on the side wall of the rigid housing perpendicular to the thickness direction, and a side adhesive layer is provided on the side of the circuit board corresponding to the positioning protrusion. The positioning protrusion and the side adhesive layer are locked together at the end away from the metal housing, and the side adhesive layer is squeezed tightly to the side wall of the rigid housing.

[0013] Alternatively, the rigid casing may be made of materials such as stainless steel, stainless iron, hard plastic, or zinc alloy.

[0014] Optionally, multiple adhesive holes are opened on both sides of the rigid housing perpendicular to the thickness direction, and there are gaps between the circuit board and the rigid housing on both sides perpendicular to the thickness direction of the rigid housing.

[0015] This utility model also discloses a power bank, which is equipped with the aforementioned data cable.

[0016] Compared with the prior art, the beneficial effects of the data cable provided by this utility model are as follows: The data cable of this utility model is provided with a rigid sheath, which is fitted over the circuit board, and one end is positioned on the metal outer shell. In this way, the force exerted during insertion and removal of the metal outer shell can be distributed to the rigid sheath. At the same time, the rigid sheath has adhesive holes. While the outer adhesive layer of the coating structure covers the rigid sheath, the gap between the circuit board and the inner cavity wall of the rigid sheath is filled with an inner adhesive layer, and the outer and inner adhesive layers are connected as one unit through the connecting adhesive layer in the adhesive holes. In this way, the inner and outer parts of the rigid sheath are wrapped and filled by the coating structure and connected through the adhesive holes. The inner and outer coating structures of the rigid sheath are integrally connected and form a nested locking position with the rigid sheath, improving the overall structural strength of the coating structure, the rigid sheath, and the connector. Therefore, even if the data cable of this utility model is subjected to force during prolonged insertion and removal, it is not easy for the metal outer shell to separate from the coating structure or break.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a data cable 1, such as Figures 1 to 8As shown, the data cable 1 includes a connector 11, a rigid housing 12, and an adhesive-coated structure 13. The connector 11 includes a circuit board 111 and a metal housing 112, which are fixedly connected. The rigid housing 12 has an inner cavity 126 and is fitted over the connector 11. One end of the metal housing 112 extends out of the rigid housing 12 and is fixedly connected to it. Inside the rigid housing 12, there is a gap 14 between the circuit board 111 and the wall of the inner cavity 126. The rigid housing 12 has an adhesive-coated hole 121 that connects the inner cavity 126 to the outside. The encapsulation structure 13 includes an outer adhesive layer 131 covering the rigid housing 12, an inner adhesive layer 132 filling the gap 14 between the circuit board 111 and the inner cavity 126 wall of the rigid housing 12, and a connecting adhesive layer 133 located in the glue passage 121 to connect the outer adhesive layer 131 and the inner adhesive layer 132; the outer adhesive layer 131, the inner adhesive layer 132 and the connecting adhesive layer 133 are integrally formed.

[0030] When in use, the data cable 1 of this utility model has its metal outer shell 112 inserted into the charging port of an electronic device, such as a mobile phone, for charging or data transfer. When the data cable 1 is used as a component in a portable power bank, it is generally only used for charging.

[0031] The data cable 1 of this utility model is provided with a rigid sleeve 12, on which a circuit board 111 is fitted, and one end is positioned on the metal outer shell 112. In this way, the force of insertion and removal during use of the metal outer shell 112 can be distributed to the rigid sleeve 12. At the same time, the rigid sleeve 12 has a through hole 121. While the outer adhesive layer 131 of the encapsulation structure 13 covers the rigid sleeve 12, the gap between the circuit board 111 and the inner cavity 126 wall of the rigid sleeve 12 is filled with the inner adhesive layer 132. The outer adhesive layer 131 and the inner adhesive layer 132 are connected as one unit through the connecting adhesive layer 133 in the through hole 121. In this way, the inner and outer parts of the rigid sleeve 12 are wrapped and filled by the encapsulation structure 13 and connected through the through hole 121. The encapsulation structure 13 inside and outside the rigid sleeve 12 is integrally connected and forms a nested locking position with the rigid sleeve 12, which improves the overall structural strength of the encapsulation structure 13, the rigid sleeve 12 and the connector 11. Therefore, even if the data cable 1 of this utility model is subjected to force during long-term plugging and unplugging, it is not easy for the metal shell 112 to separate from the rubber-coated structure 13 or to break.

[0032] Specifically, the rigid housing 12 houses the circuit board 111. This can be achieved through direct contact between the circuit board 111 and the rigid housing 12, or simply by placing the circuit board 111 inside the rigid housing 12 without direct contact between them. During injection molding to form the overmolded structure 13, the rigid housing 12, through positioning within the metal housing 112 and with the aid of jigs in the processing equipment, ensures the correct positions of the rigid housing 12, the metal housing 112, and the circuit board 111, guaranteeing the proper injection molding formation of the overmolded structure 13.

[0033] Specifically, such as Figure 4 As shown, one end of the rigid sleeve 12 has a positioning window 122 that matches the outline of the metal outer shell 112. The metal outer shell 112 passes through the positioning window 122 and is tightly connected to it. The design of the positioning window 122 allows one end of the rigid sleeve 12 to be mounted on the metal outer shell 112, ensuring the installation between the rigid sleeve 12 and the metal outer shell 112. The positioning window 122 is in close contact with the surface of the metal outer shell 112, increasing the lateral support force on the metal outer shell 112. This effectively transfers and distributes the force during insertion and removal to the rigid sleeve 12, rather than directly acting on the metal outer shell 112 or the circuit board 111, preventing the metal outer shell 112 from "breaking off". Furthermore, after the rigid sleeve 12 is initially positioned, the adhesive structure 13 applies adhesive to the end of the rigid sleeve 12 where the positioning window 122 is located, ensuring the fixation of the rigid sleeve 12.

[0034] like Figure 6 and Figure 7 As shown, at one end near the positioning window 122, first positioning ribs 123 are provided on the opposite side walls of the inner cavity 126 of the rigid housing 12. The two sides of the circuit board 111 abut against the corresponding first positioning ribs 123. The abutment and cooperation between the first positioning ribs 123 and the two sides of the circuit board 111 enables the circuit board 111 to achieve initial positioning within the rigid housing 12, facilitating the subsequent injection molding of the encapsulation structure 13.

[0035] Connector 11 includes an inner connecting layer 113, which is located between and connected to both the circuit board 111 and the metal housing 112. The inner connecting layer 113 encapsulates the connecting lines or contact springs between the circuit board 111 and the metal housing 112, effectively enhancing the bonding strength between them and preventing loosening or poor contact due to frequent insertion / removal or external forces. The inner connecting layer 113 also provides additional insulation protection for the circuit board 111 and the metal housing 112, preventing short circuits or leakage caused by external factors (such as dust and moisture), thereby improving the electrical safety of connector 11. The design of the inner connecting layer 113 also provides assembly positioning for the rigid housing 12, facilitating its initial installation and positioning.

[0036] Specifically, the metal casing 112 can be a Lightning interface, a Type-C interface, or a Micro USB-A interface, etc. The specific connection between the metal casing 112 and the circuit board 111 can use conventional technology, which will not be described in detail here.

[0037] Near the positioning window 122, a second positioning rib 124 is provided on both side walls of the rigid housing 12 perpendicular to the thickness direction. The second positioning rib 124 is pressed tightly against both sides of the inner connecting rubber layer 113. The pressing fit between the second positioning rib 124 and the inner connecting rubber layer 113 further enhances the installation and positioning of the connector 11 in the rigid housing 12, and works together with the first positioning rib 123 to position the connector 11. The second positioning rib 124 also provides a clear assembly position for the inner connecting rubber layer 113, enabling the inner connecting rubber layer 113 to be installed quickly and accurately, simplifying the assembly process and improving production efficiency.

[0038] Specifically, such as Figure 6 and Figure 7 As shown, the rigid housing 12 has an opening at one end away from the window, and the first positioning rib 123 and the second positioning rib 124 are set as inclined surfaces 15 at the ends away from the window. The inclined surfaces 15 facilitate the installation of the circuit board 111 between the first positioning rib 123 and the second positioning rib 124.

[0039] Furthermore, the rigid housing 12 is made of materials such as stainless steel, stainless iron, hard plastic, or zinc alloy. Stainless steel has extremely high strength and wear resistance, effectively withstanding the impact of external forces during frequent insertion and removal, reducing wear caused by friction. Stainless iron has high strength and toughness, able to withstand significant external forces during frequent insertion and removal while maintaining good structural stability. It offers high cost-effectiveness while ensuring the durability and reliability of the connecting metal housing 112, making it suitable for mass production and application. Hard plastic has lower processing costs and lower density, making the connecting metal housing 112 lighter. It also has good insulation properties, effectively preventing electrical short circuits or leakage, and improving the electrical safety of the connecting metal housing 112. Zinc alloy has high strength and hardness, effectively withstanding the impact of external forces during frequent insertion and removal, reducing deformation or damage caused by external forces. Simultaneously, zinc alloy has good casting properties, allowing for the fabrication of complex-shaped rigid housings 12 through injection molding or die casting processes to meet diverse design requirements. Rigid plastics can be blends of acrylonitrile-butadiene-styrene copolymer (ABS) and polycarbonate (PC).

[0040] Multiple glue-passing holes 121 are formed on both sides of the rigid housing 12 perpendicular to the thickness direction. Gaps 14 exist between the circuit board 111 and the rigid housing 12 on both sides perpendicular to the thickness direction. The multiple glue-passing holes 121 on both sides of the rigid housing 12 perpendicular to the thickness direction improve the rapid injection of plastic into the rigid housing 12 during the injection molding process of the overmolding structure 13. Furthermore, there are multiple nesting and engaging points between the overmolding structure 13 and the rigid housing 12, and multiple integral connection points exist between the overmolding structures 13 inside and outside the rigid housing 12, forming multiple connecting adhesive layers and improving the overall structural strength of the connecting metal housing 112.

[0041] Furthermore, in one embodiment, such as Figure 6 As shown, a positioning protrusion 125 is provided on the sidewall of the rigid housing 12 perpendicular to the thickness direction. The positioning protrusion 125 engages with the end of the circuit board 111 away from the metal housing 112. This engagement of the positioning protrusion 125 with the end of the circuit board 111 away from the metal housing 112 effectively fixes the position of the circuit board 111 within the rigid housing 12, improving the installation and positioning effect of the connector 11 within the rigid housing 12, facilitating the injection molding overmolding structure 13, and enhancing the overall structural strength of the connecting metal housing 112. In this embodiment, the positioning protrusion 125 directly engages with the circuit board 111. Specifically, an inclined surface 15 is provided on the end of the positioning protrusion 125 away from the metal housing 112 to facilitate the assembly of the connector 11 into the rigid housing 12. In another embodiment, as... Figure 4 and Figure 6As shown, a positioning protrusion 125 is provided on the sidewall of the rigid housing 12 perpendicular to the thickness direction. A side-coating layer 114 is provided on the side of the circuit board 111 corresponding to the positioning protrusion 125. The positioning protrusion 125 and the side-coating layer 114 are engaged at the end away from the metal housing 112. This engagement effectively fixes the position of the circuit board 111 within the rigid housing 12, improving the installation and positioning effect of the connector 11 within the rigid housing 12, facilitating the injection molding of the coating structure 13, and enhancing the overall structural strength of the connecting metal housing 112. In this embodiment, the positioning protrusion 125 and the side-coating layer 114 are engaged, and further, the side-coating layer 114 is pressed tightly against the sidewall of the rigid housing 12, further improving the installation and positioning of the connector 11. Specifically, an inclined surface 15 is provided on the end of the positioning protrusion 125 away from the metal housing 112, facilitating the assembly of the connector 11 into the rigid housing 12.
