Some existing data cables are equipped with protective covers to protect them, but the protective cover and the data cable are usually connected by injection molding, which makes the manufacturing cost of the data cable very high. [Utility Model Content]

[0003] In order to solve the problem that the existing data cables are not beautiful enough and have high manufacturing costs, the utility model provides a connector terminal, which includes a joint, a wire, an inner shell and an outer shell.

[0004] Preferably, a protrusion or a groove is provided on the outer surface of the inner shell, and a groove or a protrusion is provided on the inner surface of the corresponding outer shell, and the protrusion is snap-fitted into the groove.

[0005] Preferably, a protrusion is provided on the outer surface of the inner shell, and a groove is provided on the inner surface of the outer shell. The protrusion and the groove are respectively provided at one end of the inner shell and the outer shell close to the joint, and the height of the protrusion gradually increases along the direction of the wire pointing to the joint.

[0006] Preferably, a plurality of protrusions are provided, and the protrusions are arranged in an annular manner around the outer surface of the inner shell.

[0007] Preferably, the protrusions are arranged in multiple circles around the outer surface of the inner shell at intervals, and multiple grooves are arranged corresponding to the positions of the protrusions.

[0008] Preferably, a mesh groove is provided on the outer surface of the inner shell, glue is placed in the mesh groove, and the mesh groove and the protrusion are arranged at intervals on the inner shell.

[0009] Preferably, a flow limiting groove is further provided on the outer surface of the inner shell, and the flow limiting groove is provided on both sides of the mesh groove respectively close to the joint and the wire, and the flow limiting groove is connected to the mesh groove.

[0010] Preferably, a heat dissipation groove is provided on the outer surface of the inner shell at one end close to the wire.

[0011] Preferably, the housing is at least partially configured as a transparent area.

[0012] To explain the above technical problem, the utility model also provides an electrical connection device, which includes a connector and a connector terminal, and the wires of the connector and the connector terminal are electrically connected.

[0013] Compared with the prior art, the connector terminal and electrical connection device provided by the utility model have the following advantages:

[0014] 1. The connector terminal provided by the utility model is provided with an inner shell to wrap the connection area of ​​the joint and the wire, and an outer shell is provided to be sleeved on the inner shell, so that the outer shell and the inner shell are connected by a snap. The utility model makes the connector terminal more beautiful by sleeved the outer shell on the inner shell, and the outer shell can protect the connector terminal, thereby avoiding damage to the connector terminal during repeated plugging and unplugging. At the same time, the outer shell and the inner shell are connected by a snap, and the manufacturing cost of the connector terminal is lower than that of the existing outer shell and inner shell formed by injection molding. Furthermore, the outer surface of the inner shell and the inner surface of the outer shell are at least partially glued together. By bonding the inner shell and the outer shell, on the basis of the outer shell and the inner shell being connected by a snap, the tensile strength of the outer shell is improved, and the connection between the outer shell and the inner shell is made more stable.

[0015] 2. The outer surface of the inner shell of the connector terminal provided by the utility model is provided with a protrusion or a groove, and the inner surface of the corresponding outer shell is provided with a groove or a protrusion, and the protrusion is snapped into the groove. The inner shell and the outer shell are snap-fitted by the protrusion and the groove. Since the outer shell is sleeved on the inner shell, the outer shell itself is restricted by the inner shell and can only move along the axial direction of the inner shell. By setting the protrusion and the groove, the movement of the outer shell in the axial direction of the inner shell can be restricted, so that the inner shell and the outer shell can be relatively fixed while the structure is simple.

[0016] 3. The connector terminal provided by the utility model is provided with a protrusion on the outer surface of the inner shell, and a groove on the inner surface of the outer shell. The protrusion and the groove are respectively provided at one end of the inner shell and the outer shell close to the joint, and the height of the protrusion gradually increases along the direction of the wire pointing to the joint. The installation of the outer shell usually starts from one end of the connecting wire and is put on the inner shell. The protrusion and the groove are provided at the end close to the joint. The process from the outer shell being put on the inner shell until it contacts the protrusion is very smooth, which can make the installation of the outer shell easier. At the same time, the height of the protrusion gradually increases along the direction of the wire pointing to the joint, which allows the outer shell to slide over the protrusion more smoothly until the protrusion completely enters the groove, making the installation of the connector terminal more convenient.

[0017] 4. The connector terminal provided by the utility model has multiple protrusions, and the protrusions are arranged in a ring-shaped interval around the outer surface of the inner shell. Compared with a complete circle of protrusions, the multiple protrusions arranged in a broken interval avoid the stress concentration caused by the protrusions being squeezed by the outer shell during installation, improve the strength of the protrusions, and enhance the flexibility of the structure, making it easier to disassemble and assemble.

[0018] 5. The protrusions of the connector terminal provided by the utility model can be arranged in multiple circles around the outer surface of the inner shell, and multiple grooves can be arranged corresponding to the positions of the protrusions. The tensile strength of the outer shell can be further improved by arranging multiple circles of protrusions and grooves, and different numbers of protrusions and grooves can be selected according to different product requirements.

[0019] 6. The outer surface of the inner shell of the connector terminal provided by the utility model is provided with a mesh groove, the glue is provided in the mesh groove, and the mesh groove and the protrusion are provided at intervals on the inner shell. By placing the glue in the mesh groove, the glue will not exceed the outer surface of the inner shell, the inner shell and the outer shell can be close together, and a gap between the inner shell and the outer shell is avoided.

[0020] 7. The outer surface of the inner shell of the connector terminal provided by the utility model is also provided with a current limiting groove, which is provided on both sides of the mesh groove close to the connector and the wire respectively, and the current limiting groove is connected to the mesh groove. When glue is placed in the mesh groove, too much glue placed or glue that is shaken during installation will flow into the current limiting grooves on both sides of the mesh groove, thereby preventing the glue from flowing onto the connector and wire on both sides of the inner shell.

[0021] 8. The outer surface of the inner shell of the connector terminal provided by the utility model is provided with a heat dissipation groove at one end close to the wire. The connector includes electronic components, which are generally close to the wire direction when the connector is electrically connected. The inner shell is provided with a heat dissipation groove at the position corresponding to the electronic component. The heat dissipation groove can form an air circulation channel between the inner shell and the outer shell, which is helpful for heat dissipation. The heat dissipation groove can help improve the heat dissipation performance of the overall structure.

[0022] 9. The outer shell of the connector terminal provided by the utility model is at least partially set as a transparent area. The inner shell can be observed in the transparent area, and different patterns or texts are set on the outer surface of the inner shell to make the connector terminal more beautiful and have a display function.

[0023] 10. The utility model also provides an electrical connection device, which includes a connector and a connector terminal, and the wires of the connector and the connector terminal are electrically connected. The electrical connection device has the same beneficial effects as the above connector terminal, which will not be described in detail here.

[0042] To solve the problem that the existing data cable is not beautiful and has high manufacturing cost, please refer to Figure 1 and Figure 2 The first embodiment of the utility model provides a connector terminal 1, which includes a connector 13, a wire 11, an inner shell 14 and an outer shell 12. The connector 13 and the wire 11 are electrically connected, and the inner shell 14 wraps the connection area between the connector 13 and the wire 11; the outer shell 12 is sleeved on the inner shell 14, and the outer shell 12 and the inner shell 14 are snap-connected; the outer surface of the inner shell 14 and at least a portion of the inner surface of the outer shell 12 are adhesively connected.

[0043] The connector terminal 1 provided in this embodiment protects the electrical connection area between the connector 13 and the wire 11 by providing an inner shell 14 to wrap the connection area between the connector 13 and the wire 11. The outer shell 12 is provided to be sleeved on the inner shell 14, and the outer shell 12 covers the inner shell 14 to provide a different appearance for the connector terminal 1, which can make the connector terminal 1 more beautiful. At the same time, the outer shell 12 can protect the connector terminal 1, avoiding damage to the connector terminal 1 during multiple plugging and unplugging.

[0044] In addition, the outer shell 12 and the inner shell 14 are connected by snapping, and the manufacturing cost of the connector terminal 1 is lower than that of the existing outer shell 12 and the inner shell 14 formed by injection molding. In this embodiment, glue is also provided on the outer surface of the inner shell 14 and / or the inner surface of the outer shell 12, so that the inner shell 14 and the outer shell 12 are bonded to each other. On the basis of the outer shell 12 and the inner shell 14 being connected by snapping, the tensile strength of the outer shell 12 is improved, so that the connection between the outer shell 12 and the inner shell 14 is more stable.

[0045] For details, please refer to Figure 3 and Figure 4 The outer surface of the inner shell 14 is provided with a protrusion 141 or a groove 121 , and the inner surface of the outer shell 12 is correspondingly provided with a groove 121 or a protrusion 141 , and the protrusion 141 is snap-fitted into the groove 121 .

[0046] The inner shell 14 and the outer shell 12 are snap-connected by means of the protrusion 141 and the groove 121. Since the outer shell 12 is sleeved on the inner shell 14, the outer shell 12 itself is restricted by the inner shell 14 and can only move axially along the inner shell 14. By setting the protrusion 141 and the groove 121, the movement of the outer shell 12 in the axial direction of the inner shell 14 can be restricted, so that the inner shell 14 and the outer shell 12 can be relatively fixed while having a simple structure.

[0047] For further information, please refer to Figure 3 and Figure 4 A protrusion 141 is provided on the outer surface of the inner shell 14, and a groove 121 is provided on the inner surface of the outer shell 12. The protrusion 141 and the groove 121 are respectively provided at one end of the inner shell 14 and the outer shell 12 close to the connector 13, and the height of the protrusion 141 gradually increases along the direction of the wire 11 pointing to the connector 13.

[0048] The installation of the outer shell 12 usually starts from one end of the connecting wire 11 and is put on the inner shell 14. The protrusion 141 and the groove 121 are set at the end close to the connector 13. The process from the outer shell 12 being put on the inner shell 14 until it contacts the protrusion 141 is very smooth, which can make the installation of the outer shell 12 easier. At the same time, the height of the protrusion 141 gradually increases along the direction of the wire 11 pointing to the connector 13, which allows the outer shell 12 to slide over the protrusion 141 more smoothly until the protrusion 141 completely enters the groove 121, making the installation of the connector terminal 1 more convenient.

[0049] Specifically, see Figure 4 When the protrusion 141 is engaged with the groove 121 , only the higher side of the protrusion 141 contacts the groove 121 , and the height of the protrusion 141 is much lower than the depth of the groove 121 .

[0050] The outer shell 12 is sleeved on the inner shell 14 from one side of the wire 11. Only a through hole is set on the end of the outer shell 12 close to the wire 11, and the wire 11 passes through the through hole of the outer shell 12. When the outer shell 12 is completely sleeved on the inner shell 14, the end of the outer shell 12 with the through hole abuts against the inner shell 14, limiting the outer shell 12 from moving further toward the connector 13. At the same time, the higher side of the protrusion 141 contacts the groove 121, limiting the outer shell 12 from moving toward the wire 11. Through the clamping of the protrusion 141 and the groove 121 and the abutment of the outer shell 12 and the inner shell 14, the outer shell 12 is fixed in the axial direction of the inner shell 14.

[0051] The protrusion 141 and the groove 121 are only in contact on one side during the snap connection, and the height of the protrusion 141 is much lower than the depth of the groove 121, making it easier for the outer shell 12 to slide on the inner shell 14 and easier for the protrusion 141 and the groove 121 to be snap-connected.

[0052] For details, please refer to Figure 5 and Figure 6 A plurality of protrusions 141 are provided, and the protrusions 141 are arranged in an annular manner around the outer surface of the inner shell 14 at intervals.

[0053] Compared with a complete circle of protrusions 141, a plurality of protrusions 141 with interrupted intervals can avoid stress concentration caused by squeezing the protrusions 141 during installation of the housing 12, improve the strength of the protrusions 141, and enhance the flexibility of the structure, making disassembly and assembly easier.

[0054] Optionally, the protrusions 141 are arranged in multiple circles around the outer surface of the inner shell 14, and the grooves 121 are arranged in multiple circles corresponding to the positions of the protrusions 141. The tensile strength of the outer shell 12 can be further improved by arranging multiple circles of protrusions 141 and grooves 121, and different numbers of protrusions 141 and grooves 121 can be selected according to different product requirements.

[0055] For details, please refer to Figure 5 and Figure 6 A mesh groove 143 is arranged on the outer surface of the inner shell 14 , the glue is arranged in the mesh groove 143 , and the mesh groove 143 and the protrusion 141 are arranged at intervals on the inner shell 14 .

[0056] By placing the glue in the mesh groove 143, the glue does not exceed the outer surface of the inner shell 14, and the inner shell 14 and the outer shell 12 can be close to each other, thereby avoiding the appearance of a gap between the inner shell 14 and the outer shell 12. At the same time, the mesh groove 143 can increase the bonding area between the inner shell 14 and the outer shell 12, thereby improving the bonding and fixing effect of the glue.

[0057] Furthermore, a flow limiting groove 142 is further provided on the outer surface of the inner shell 14 . The flow limiting groove 142 is provided on both sides of the mesh groove 143 close to the connector 13 and the wire 11 , respectively, and the flow limiting groove 142 is connected to the mesh groove 143 .

[0058] When glue is placed in the mesh groove 143 , glue that is placed too much or shaken during installation will flow into the flow limiting grooves 142 on both sides of the mesh groove 143 , preventing the glue from flowing onto the connectors 13 and wires 11 on both sides of the inner shell 14 .

[0059] Specifically, the mesh grooves 143 and the current limiting grooves 142 are arranged on a side of the protrusion 141 close to the wire 11 .

[0060] For details, please refer to Figure 5 and Figure 6 A heat dissipation groove 144 is provided on the outer surface of the inner shell 14 at one end close to the wire 11 .

[0061] The connector 13 includes electronic components. When the connector 13 is electrically connected, the electronic components are generally close to the wire 11. The inner shell 14 is provided with a heat dissipation groove 144 at the position corresponding to the electronic components. The heat dissipation groove 144 can form an air circulation channel between the inner shell 14 and the outer shell 12, which is helpful for heat dissipation. The heat dissipation groove 144 can help improve the heat dissipation performance of the overall structure.

[0062] Specifically, the outer shell 12 is a metal shell 12, preferably, an aluminum shell. Meanwhile, the inner shell 14 is a TPE or PVC material formed by injection molding. The metal shell 12 can give the user a better feel, making the product more textured, and at the same time, the metal shell 12 can play a better protective role.

[0063] Optionally, at least part of the outer shell 12 is set as a transparent area. The inner shell 14 can be observed through the transparent area, and by setting different patterns or texts on the outer surface of the inner shell 14, the connector terminal 1 is more beautiful and has a display function.

[0064] The connector terminal 1 provided in the first embodiment is provided with a protrusion 141 and a groove 121 on the inner shell 14 and the outer shell 12, respectively, so that the outer shell 12 can be connected to the inner shell 14, and the outer shell 12 can protect the inner shell 14 while making the connector terminal 1 more beautiful. At the same time, glue is provided on the inner shell 14 so that the inner shell 14 and the outer shell 12 are bonded to each other. On the basis of the snap connection between the inner shell 14 and the outer shell 12, the inner shell 14 and the outer shell 12 are further fixed, thereby improving the stability and tensile strength of the outer shell 12.

[0065] To solve the above technical problems, please refer to Figure 7The second embodiment of the utility model further provides an electrical connection device 2, which includes a connector 21 and a connector terminal 1, and the connector 21 is electrically connected to the wire 11 of the connector terminal 1. The electrical connection device 2 has the same beneficial effects as the above connector terminal 1, which will not be described in detail here.
