[0030] Please see Figures 1 to 3 This application provides a connector 100, which can be a data cable, an earphone cable, or other connectors. For ease of description, the following explanation will use a data cable as an example.

[0031] The connector 100 includes a plug 110, a connecting body 130, a connecting wire 150, an annular housing 170, and an annular injection molded housing 190.

[0032] The connecting body 130 is connected to the plug 110, and the connecting wire 150 passes through the connecting body 130 and is connected to the plug 110. The connecting wire 150 is used for power and / or data transmission, and the plug 110 can be used to plug into the interface of electrical equipment (such as the interface of mobile phone, tablet computer, laptop computer, etc.) or power supply (such as socket).

[0033] The connector 110 can be a Type-C connector, a USB connector, or other connectors.

[0034] As an example, the connector 110 and the connecting wire 150 are respectively connected to opposite sides of the connecting body 130, and both are partially located within the connecting body 130 and electrically connected to each other. Specifically, the connector 100 may also include a control board 210, one end of the connecting wire 150 may be connected to the control board 210, the connector 110 may be connected to the control board 210, and the connecting body 130 may be injection molded to cover the control board 210, and cover part of the connecting wire 150 and part of the connector 110, so that the connecting body 130 can fix the connector 110 and the connecting wire 150. The other end of the connecting wire 150 may also be connected to another connector 110 through the control board 210, or the other end of the connecting wire 150 may also be connected to a charging head, which is not limited in this embodiment. When both ends of the connecting wire 150 are connected to the connector 110, the connectors 110 at both ends of the connecting wire 150 may be the same or different.

[0035] An annular outer shell 170 is fitted onto the connecting body 130, forming an annular injection space 230 between them. An annular injection shell 190 is at least partially disposed within the annular injection space 230. The annular injection shell 190 is used to bond and fix the connecting body 130 and the annular outer shell 170. Thus, the annular injection space 230 provides injection space for the annular injection shell 190. The annular injection shell 190 itself can be bonded and fixed to both the annular outer shell 170 and the connecting body 130, thereby bonding and fixing the annular outer shell 170 to the connecting body 130 without requiring additional dispensing, simplifying the assembly process of the connector 100 and increasing production speed. Furthermore, since both the annular injection shell 190 and the annular outer shell 170 adopt an annular structure, it helps to increase the bonding area between the annular injection shell 190 and the connecting body 130 and the annular outer shell 170 respectively, thereby improving the situation where the annular outer shell 170 detaches from the connecting body 130.

[0036] The annular injection molded shell 190 is used to bond and fix the main body 130 and the annular outer shell 170. This means that the annular injection molded shell 190 itself is adhesive and can be bonded and fixed to the main body 130 and the annular outer shell 170 respectively.

[0037] The annular injection molded shell 190 can refer to a rigid shell formed by injecting rubber material into the annular injection space 230 and then cooling it, as specifically described in the following embodiments.

[0038] In some embodiments, the annular injection-molded shell 190 may be a rigid shell.

[0039] As an example, the Shore hardness of the annular injection molded shell 190 can be ≥85A and ≤105A, which helps the annular injection molded shell 190 to have high hardness and reduce the chance of the annular injection molded shell 190 being scratched by external structures.

[0040] In some embodiments, the annular injection-molded housing 190 may be a light-transmitting housing, which helps to improve the aesthetics of the connector 100. Specifically, the annular injection-molded housing 190 may be a transparent housing.

[0041] In some embodiments, the annular injection-molded shell 190 is a shell formed by curing a liquid viscous adhesive. The liquid viscous adhesive can be injected into the annular injection space 230 by injection molding to bond the main body 130 and the annular shell 170 after curing, which helps to make the connection between the main body 130 and the annular shell 170 more secure.

[0042] As an example, the adhesive compound can be a transparent adhesive compound, which is a novel, one-component, fully transparent solution adhesive that, after curing, forms a transparent ring-shaped injection-molded shell 190. This novel, one-component, fully transparent solution adhesive has advantages such as room temperature curing, ease of operation, high bonding strength, rapid positioning, high elasticity, soft film, and non-toxic cured product. Furthermore, it possesses excellent properties such as water resistance, heat resistance, acid resistance, alkali resistance, corrosion resistance, oil resistance, and no whitening. The adhesive compound can be used for bonding the same or different materials such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene styrene plastic (ABS), polystyrene (PS), polymethyl methacrylate (PMMA), nylon, sponge, film, metal, and non-metal.

[0043] The proportions of the adhesive compound can be set according to requirements.

[0044] As an example, the adhesive compound may include 5% to 40% of a mixture of styrene and butadiene styrene rubber, 5% to 40% of polypropylene, 15% to 35% of white oil, 5% to 20% of calcium carbonate, and 5% to 15% of other adhesive substances or mixtures of adhesive substances.

[0045] Understandably, when injection molding viscous material, a mold can be made first, and then the connecting body 130, the annular shell 170 and part of the connecting line 150 can be placed into the inner cavity of the mold. The viscous material is then injected into the inner cavity of the mold, and flows into the annular injection space 230. After cooling, it forms the annular injection shell 190.

[0046] Please see Figures 2 to 4 In some embodiments, the outer peripheral surface of the connecting body 130 may be provided with a first protrusion 131, and the inner peripheral wall of the annular injection molded shell 190 may be provided with a first groove 191. The first protrusion 131 can be inserted into the first groove 191, and the annular injection molded shell 190 can be bonded and fixed to the first protrusion 131. In this way, the cooperation between the first protrusion 131 and the first groove 191 can prevent the annular injection molded shell 190 from moving relative to the connecting body 130 along the radial direction of the first protrusion 131, thereby increasing the mechanical interlocking force between the annular injection molded shell 190 and the connecting body 130, which helps to make the connection between the annular injection molded shell 190 and the connecting body 130 more secure, thereby improving the connection strength between the annular injection molded shell 190 and the connecting body 130.

[0047] The shape of the first protrusion 131 can be chosen in several ways.

[0048] As an example, the first protrusion 131 may be a cylindrical protrusion, a prismatic protrusion, an elliptical cylindrical protrusion, a semi-cylindrical protrusion, or a protrusion of other shapes.

[0049] The protrusion height of the first protrusion 131 can be flexibly set according to actual needs.

[0050] As an example, the protrusion height of the first protrusion 131 relative to the outer peripheral surface of the connecting body 130 is approximately 0.55 mm.

[0051] In some embodiments, the outer peripheral surface of the connecting body 130 may be provided with a plurality of first protrusions 131, and the annular injection molded shell 190 may be provided with a plurality of first grooves 191.

[0052] The first groove 191 and the first protrusion 131 correspond one-to-one, that is, each first protrusion 131 can be inserted into a corresponding first groove 191.

[0053] The multiple first protrusions 131 can be two first protrusions 131, three first protrusions 131, four first protrusions 131, five first protrusions 131 or other numbers of first protrusions 131, and the number of first grooves 191 can be equal to the number of first protrusions 131.

[0054] Each first groove 191 penetrates the annular injection shell 190. Multiple first protrusions 131 are distributed circumferentially around the connecting body 130. Each first protrusion 131 passes through the corresponding first groove 191 and abuts against the inner circumferential wall of the annular shell 170. This allows the multiple first protrusions 131 to abut against the inner circumferential wall of the annular shell 170, thereby positioning the annular shell 170 and providing a more stable annular injection space 230 for injecting viscous adhesive. This facilitates the injection of viscous adhesive into the annular injection space 230, improving stability during injection molding. Furthermore, the inner wall of each first groove 191 can be bonded and fixed to the outer circumferential wall of the corresponding first protrusion 131, further enhancing the bonding strength between the annular injection shell 190 and the connecting body 130.

[0055] As an example, the connecting body 130 is generally elliptical cylinder, and the connecting line 150 and the connector 110 are respectively connected to opposite ends of the connecting body 130 along the axial direction. The outer peripheral surface of the connecting body 130 may have four first protrusions 131, two of which are distributed along a first radial direction on opposite sides of the connecting body 130, and the other two are distributed along a second radial direction on opposite sides of the connecting body 130. The first and second radial directions may be perpendicular or approximately perpendicular to each other. The annular injection-molded shell 190 may also have four first grooves 191, the positions of which can be set according to the positions of the corresponding first protrusions 131, which will not be elaborated further.

[0056] It should be noted that the shapes of the multiple first protrusions 131 can be the same or different, and each first groove 191 can be adapted to the shape of the corresponding first protrusion 131.

[0057] In some embodiments, the outer peripheral wall of the connecting body 130 is provided with an annular groove 135, the annular groove 135 communicates with the annular injection space 230, and the first protrusion 131 is provided in the annular groove 135.

[0058] As an example, the annular groove 135 may be provided around the outer periphery of the connecting body 130. The annular groove 135 may include an annular groove 135 opening, an annular bottom wall, and two annular side walls, the two annular side walls extending from the annular groove 135 opening to the annular bottom wall, the annular groove 135 opening communicating with the annular injection space 230. A first protrusion 131 may protrude from the annular bottom wall and extend into the annular injection space 230 to be inserted into the first groove 191. Understandably, the protrusion height of the first protrusion 131 relative to the annular bottom wall is approximately 0.55 mm.

[0059] The inner peripheral wall of the annular injection molded shell 190 is provided with an annular protrusion 192. The annular protrusion 192 protrudes into the annular groove 135 and is respectively bonded and fixed to the inner wall of the annular groove 135 and the first protrusion 131, thereby increasing the mechanical interlocking force between the annular injection molded shell 190 and the connecting body 130, which helps to make the connection between the annular injection molded shell 190 and the connecting body 130 more secure.

[0060] The first groove 191 is provided on the annular protrusion 192 so that the first protrusion 131 can be inserted, and the first protrusion 131 and the annular protrusion 192 interfere with each other.

[0061] In some embodiments, the connecting body 130 is provided with an installation channel 133, the plug 110 is partially inserted into one end of the installation channel 133, and the connecting wire 150 passes through the other end of the installation channel 133 to connect to the plug 110.

[0062] As an example, the control board 210 may be located within the mounting channel 133, with the connecting cable 150 and the connector 110 both partially located within the mounting channel 133 to connect to the control board 210, and extending outward from the channel openings at opposite ends of the mounting channel 133.

[0063] The inner wall of the annular groove 135 may be recessed with a second groove 137, which can connect the installation channel 133 and the annular groove 135. The inner wall of the annular protrusion 192 is provided with a second protrusion 193, which can be inserted into the second groove 137 and bonded to the inner wall of the second groove 137, which helps to further improve the bonding strength between the connecting bodies 130 of the annular injection molded shell 190.

[0064] The second groove 137 can be a groove structure formed by the mold positioning pin on the connecting body 130 when the injection molding connecting body 130 is performed.

[0065] As an example, during injection molding of the connecting body 130, a mold positioning pin can be used to abut against the connecting line 150 to prevent the connecting line 150 from being misaligned during injection molding. After injection molding of the connecting body 130, the mold positioning pin can be removed, leaving a second groove 137 on the connecting body 130. In this embodiment, the existing second groove 137 can be used as a positioning structure for the viscous adhesive to enter. After the viscous adhesive cures, it forms a second protrusion 193 to adhere to the inner wall of the second groove 137, thereby further improving the connection strength between the annular injection-molded shell 190 and the connecting body 130. Understandably, since the viscous adhesive is a fluid liquid, it can also enter the mounting channel 133 along the second groove 137 to adhere to the connecting line 150 and the inner wall of the mounting channel 133, which helps to further improve the connection strength between the connecting line 150 and the connecting body 130.

[0066] In some embodiments, the annular injection-molded shell 190 extends from the connecting body 130 toward the connecting line 150 to partially cover the connecting line 150. Thus, the annular injection molding can also fix the connecting line 150 and the connecting body 130, which helps to improve the relative swaying of the connecting line 150 and the connecting body 130 under the action of external force and improves the connection stability between the connecting body 130 and the connecting line 150.

[0067] In some embodiments, the annular injection-molded shell 190 may include a first annular segment 195 and a second annular segment 197 connected to each other.

[0068] The first annular segment 195 can be at least partially disposed within the annular injection space 230 for bonding and fixing the annular outer shell 170 and the connecting body 130. That is, the first annular segment 195 is sleeved on the outer periphery of the connecting body 130 and bonding and fixing the annular outer shell 170 and the connecting body 130.

[0069] Understandably, the second groove 137 and the second protrusion 193 in the above embodiments are both located in the first annular segment 195, and will not be described again.

[0070] The second annular segment 197 can be sleeved on the connecting line 150 and bonded to the connecting line 150. Thus, the annular injection molding can also fix the connecting line 150 and the connecting body 130, which helps to improve the relative shaking of the connecting line 150 and the connecting body 130 under the action of external force and improves the connection stability between the connecting body 130 and the connecting line 150.

[0071] In some embodiments, the first annular segment 195 includes a first sub-annular segment 1951 and a second sub-annular segment 1953.

[0072] The second sub-ring segment 1953 can be connected between the first sub-ring segment 1951 and the second ring segment 197.

[0073] The first sub-annular segment 1951 can be disposed within the annular injection molding space 230 for bonding and fixing the annular outer shell 170 and the connecting body 130. Understandably, the second groove 137 and the second protrusion 193 in the above embodiments are both located within the first sub-annular segment 1951, and will not be described further.

[0074] The second sub-annular segment 1953 is fitted onto the connecting body 130 and exposed outside the annular housing 170. This allows the first sub-annular segment 1951 and the second annular segment 197 to cooperate, increasing the coverage length on the connecting body 130 and improving the bonding strength between the annular injection-molded housing 190 and the connecting body 130. Furthermore, since the annular injection-molded housing 190 is a light-transmitting housing, the second sub-annular segment 1953 is also light-transmitting, allowing the user to observe the connecting body 130 through it. The color of the connecting body 130 itself provides a better visual effect for the second sub-annular segment 1953, contributing to the overall aesthetic appeal of the connector 100.

[0075] In some embodiments, a stepped surface 1955 may be formed between the second sub-annular segment 1953 and the first annular segment 195. The stepped surface 1955 may be bonded and fixed to the end face of the annular housing 170, thereby avoiding the formation of a gap between the stepped surface 1955 and the end face of the annular housing 170. This helps to prevent dust and other impurities from accumulating between the stepped surface 1955 and the end face of the annular housing 170, and can improve the overall aesthetic appearance of the connector 100.

[0076] The outer circumferential surface of the second sub-annular segment 1953 is flush with the outer circumferential surface of the annular shell 170, which helps to improve the user's grip and avoids the situation where the outer circumferential surface of the second sub-annular segment 1953 is not flush with the outer circumferential surface of the annular shell 170, which would cause discomfort to the hand.

[0077] In the connector 100 provided in this embodiment, by configuring the annular outer shell 170 to be sleeved outside the connecting body 130, an annular injection space 230 can be formed between the annular outer shell 170 and the connecting body 130. The annular injection shell 190 is at least partially disposed within the annular injection space 230. The annular injection shell 190 can bond and fix the connecting body 130 and the annular outer shell 170, thereby providing injection space for the annular injection shell 190. The annular injection shell 190 itself can be bonded and fixed to both the annular outer shell 170 and the connecting body 130, thus fixing the annular outer shell 170 to the connecting body 130 without the need for additional dispensing processes, simplifying the assembly process of the connector 100 and improving production speed. By configuring both the annular injection shell 190 and the annular outer shell 170 as annular structures, it helps to increase the bonding area between the annular injection shell 190 and the connecting body 130 and the annular outer shell 170 respectively, thereby improving the situation where the annular outer shell 170 detaches from the connecting body 130.

[0078] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
