Description

Technical Field:

[0001] The utility model relates to the technical field of connector products, in particular to a TYPE-C connector with an LED backlight. Background Art:

[0002] USB TYPE-C is an interface specification, which consists of a TYPE-C plug and a TYPE-C socket. In various mobile devices and PCs, Type-C has become the data interface with the broadest development prospect.

[0003] The TYPE-C socket is mainly installed on the front panel of the chassis. However, currently, the general TYPE-C socket does not have a lighting function. During use, it is not easy to identify the socket or insert it in the wrong position due to light problems, thus making it inconvenient to perform good connector plugging, and the use effect is not ideal.

[0004] For this reason, someone proposed a Chinese utility model patent with the application number 201920638951.X and the name of a Type-C connector female seat for a luminous chassis panel data cable. The utility model discloses a Type-C connector female seat for a luminous chassis panel data cable, including a circuit board and a TYPE-C plugging female seat connected to the circuit board. A transparent sleeve is installed outside the TYPE-C plugging female seat. Two LED lamp boards are symmetrically installed inside the transparent sleeve. The LED lamp boards are electrically connected to the circuit board to achieve power-on lighting. Two through holes are symmetrically arranged outside the TYPE-C plugging female seat, and the positions of the through holes correspond to the lighting lamps on the surfaces of the corresponding LED lamp boards. The above Type-C connector female seat can emit light through the lighting lamps on the surfaces of the LED lamp boards, and the light irradiates into the interior of the TYPE-C plugging female seat through the through holes, illuminating the interior of the TYPE-C plugging female seat, facilitating the operator to find the TYPE-C plugging female seat and perform quick connector plugging, thus solving the above technical problems. However, the above Type-C connector female seat for a luminous chassis panel data cable also has the following deficiencies: The Type-C connector female seat uses two LED lamp boards installed inside the transparent sleeve to achieve lighting. It not only requires additional assembly structures to be set on the transparent sleeve for assembling and fixing the two LED lamp boards, but also needs to consider the electrical connection problem between the two LED lamp boards and the circuit board, resulting in a relatively complex structure of the Type-C connector female seat, a large number of parts, and a high cost, which is not conducive to improving the market competitiveness.

[0005] In view of this, the inventor of the present invention proposes the following technical solutions. Summary of the Utility Model:

[0014] Furthermore, in the above technical solution, an outer mold is integrally formed on the outside of the shielding housing. The wire connected to the PCB board extends out of the shielding housing, and the outer mold also wraps and fixes the rear end of the light guide body and the front end of the wire. Among them, a step is formed on the periphery of the rear end of the light guide body, and the outer mold wraps outside the step and forms a blocking portion adapted to the step.

[0015] Furthermore, in the above technical solution, an elastic arm that can generate elastic deformation and is used for fixed assembly with the panel is integrally formed on the outside of the outer mold, and a buckle portion is also integrally formed on the outside of the elastic arm.

[0016] Furthermore, in the above technical solution, a guiding rib adapted to the guiding groove in the panel is also provided on the outer surface of the outer mold; a positioning buckle is also provided on the outer surface of the outer mold, and the positioning buckle is located beside the guiding rib.

[0017] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: Since the LED lamp of the present utility model is welded and fixed on the PCB board, there is no need to additionally provide an LED lamp board, so there is no need to consider the installation problem of the LED lamp board and the connection problem between the LED lamp board and the PCB board.

[0026] The present utility model will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0027] See Figure 1-8 As shown, it is a TYPE-C connector with an LED backlight, which is applied to the field of automotive intelligent cockpits, such as in-vehicle charging, screen mirroring, etc. That is, the present utility model can be applicable to be installed on the in-vehicle charging panel.

[0028] The TYPE-C connector with an LED backlight of the present utility model includes a TYPE-C socket 1, a PCB board 2 disposed at the rear end of the TYPE-C socket 1 and electrically conductive with the TYPE-C socket 1, a light guide body 3 disposed on the TYPE-C socket 1, and an LED lamp 4 corresponding to the light guide body 3 and electrically connected to the PCB board. The LED lamp 4 and the LED backlight form an LED backlight. When the present utility model is working, the PCB board 2 controls the LED lamp 4 to emit light, and the light emitted by the LED lamp 4 is directed to the light guide body 3, and the light guide body 3 guides the light to form a background light.

[0029] Specifically, the biggest improvement of the present utility model lies in that: the LED lamp 4 is welded and fixed on the PCB board 2, and a ramp reflective surface 30 is provided at the rear end of the light guide body 3. The rear end of the light guide body 3 is sleeved around the periphery of the PCB board 2, and the ramp reflective surface 30 is distributed around the LED lamp 4; when the light emitted by the LED lamp 4 enters the rear end of the light guide body 3, the light is reflected by the ramp reflective surface 30 and then emitted towards the front end of the light guide body 3, so that the front end of the light guide body 3 guides the light to form a background light, for the purpose of indicating illumination, facilitating the user to quickly find the position of the socket 10 of the TYPE-C socket 1, and then inserting the TYPE-C plug into the socket 10 of the TYPE-C socket 1, improving the operation convenience, and at the same time increasing the aesthetic feeling and interest. In addition, since the LED lamp 4 of the present utility model is welded and fixed on the PCB board 2, there is no need to add an LED lamp board, so there is no need to consider the installation problem of the LED lamp board and the connection problem between the LED lamp board and the PCB board 2. In this way, the structural complexity of the present utility model can be simplified, and at the same time, the LED lamp board is reduced, the cost is reduced, and it is beneficial to improve the market competitiveness.

[0030] A tongue plate is provided in the socket 10 of the TYPE-C socket 1.

[0031] In this embodiment, there are two LED lamps 4, which are respectively welded and fixed to the upper and lower end surfaces of the PCB board 2, and can realize double-sided light emission, so that sufficient light can enter the light guide 3, so that the light guide 3 can be conducted more evenly to form a background light with better lighting effect.

[0032] The light guide 3 is a sleeve structure with a smooth inner hole. The rear end of the light guide 3 is provided with a circle of the sloped reflective surface 30 distributed in an annular shape, which can simultaneously reflect the light emitted by the two LED lights 4 to the front end of the light guide 3, so that the background light effect is better. At the same time, the front end of the light guide 3 can form a ring-shaped background light, which has a better indicating lighting effect, so that the user can more clearly and quickly find the position of the socket 10 of the TYPE-C socket 1.

[0033] In this embodiment, the slope reflective surface 30 has an inclination angle of 45°. Figure 6 Specifically, taking the LED lamp 4 on the upper end face of the PCB board 2 as an example, after the LED lamp 4 is powered on and emits light, the light formed by it is emitted from bottom to top toward the slope reflective surface 30, and after being reflected by the slope reflective surface 30, the light is reflected into a horizontal state, and then the light is horizontally emitted to the front end face of the light guide 3, so as to form an excellent light guiding effect.

[0034] The front end face of the light guide 3 extends to the front end face of the TYPE-C socket 1 and is flush with the front end face of the TYPE-C socket 1, so that the background light derived from the light guide 3 is directly exposed to the front end face of the TYPE-C connector and forms a ring-shaped background light, which has a better indicating lighting effect and facilitates users to more clearly and quickly find the position of the socket 10 of the TYPE-C socket 1.

[0035] The rear end of the TYPE-C socket 1 is also provided with a shielding shell 5, which is also wrapped around the periphery of the PCB board 2. The shielding shell 5 can effectively avoid the problem of external signal interference, and the shielding shell 5 is provided with a window 51 for exposing the LED lamp 4. The light guide 3 is fixedly mounted on the outside of the shielding shell 5. When the LED lamp 4 emits light, it directly passes through the window 51 to enter the light guide 3.

[0036] Among them, the specific structure of the light guide 3 is as follows: The light guide 3 includes a light guide part 31 at the front end, a reflective part 32 at the front and rear ends and larger in size than the light guide part 31, and a transition section 33 integrally connected between the light guide part 31 and the reflective part 32 and shaped like a large front and a small rear. The light guide part 31 is sleeved outside the metal shell 11 of the TYPE-C socket 1, and the reflective part 32 is sleeved outside the shielding shell 5 and covers the window 51, so that the light guide 3 can be stably wrapped outside the metal shell 11 of the TYPE-C socket 1 and the shielding shell 5. The rear end of the reflective part 32 is provided with the slope reflective surface 30 mentioned above.

[0037] There is an overlapping part between the light guide part 31 and the reflective part 32 in the horizontal direction. After the LED lamp 4 is powered on and emits light, the light formed by it shoots upward to the slope reflective surface 30. After being reflected by the slope reflective surface 30, the light is reflected into a horizontal state, and then the light can be horizontally shot to the front end face of the light guide 3, realizing a better light guiding effect.

[0038] An outer mold 6 is integrally formed outside the shielding shell 5. The wire 21 connected to the PCB board 2 extends out of the shielding shell 5. The outer mold 6 also wraps and fixes the rear end of the light guide 3 and the front end of the wire 21. Among them, a step 301 is formed around the rear end of the light guide 3. The outer mold 6 wraps outside the step 301 and forms a blocking part 61 adapted to the step 301, so as to ensure that the outer mold 6 is stably wrapped outside the shielding shell 5, the light guide 3 and the wire 21, and the blocking part 61 is adapted to the step 301 to form an anti-detachment structure, further ensuring the stability of the assembly structure.

[0039] An elastic arm 62 that can generate elastic deformation and is used for fixed assembly with the panel 7 is integrally formed outside the outer mold 6, and a buckle part 621 is also integrally formed outside the elastic arm 62.

[0040] When assembling with the panel 7, the elastic arm 62 is embedded into the panel 7 along with the outer mold 6, and the elastic arm 62 will be compressed. At the same time, the buckle part 621 outside the elastic arm 62 slides into the positioning groove inside the panel, and the compressed elastic arm 62 forms an outward elastic force, so that the buckle part 621 is stably clamped in the positioning groove, ensuring the stability of the assembly structure, effectively preventing problems such as easy loosening and detachment, and then ensuring the normal application of the product function.

[0041] A guiding rib 63 for adapting to the guiding groove inside the panel 7 is also provided on the outer surface of the outer mold 6;

[0042] The guiding rib 63 functions to guide and correct the position. When the present utility model is inserted into the panel 7, the guiding rib 63 corresponds to and mates with the guiding groove in the panel 7. As the present utility model is continuously inserted into the panel 7, the guiding rib 63 continuously slides into the guiding groove, thereby ensuring that the insertion direction of the present utility model is unique, correcting the assembly position, facilitating the smooth sliding of the buckle portion 621 outside the elastic arm 62 into the positioning groove inside the panel 7. At the same time, the guiding rib 63 also plays a certain limiting role, ensuring that the assembly structure of the present utility model and the panel 7 is more stable.

[0043] A positioning buckle 64 is further provided on the outer surface of the outer mold 6, and the positioning buckle 64 is located beside the guiding rib 63. The positioning buckle 64 is used for clamping and positioning with the panel 7 to further enhance the stability of the assembly structure.

[0044] In summary, since the LED lamp 4 of the present utility model is welded and fixed to the PCB board 2, there is no need to additionally provide an LED lamp board, so there is no need to consider the installation problem of the LED lamp board and the connection problem between the LED lamp board and the PCB board 2. This can simplify the structural complexity of the present utility model, reduce the LED lamp board at the same time, lower the cost, and is beneficial to improving the market competitiveness. At the same time, a ramp reflective surface 30 is provided at the rear end of the light guide 3, and the ramp reflective surface 30 is distributed around the LED lamp 4. When the light emitted by the LED lamp 4 enters the rear end of the light guide 3, the light is reflected by the ramp reflective surface 30 and then emitted towards the front end of the light guide 3, enabling the front end of the light guide 3 to conduct light to form background lighting, so as to achieve the purpose of indicating lighting, facilitating the user to quickly find the position of the socket 10 of the TYPE-C socket 1, and then inserting the TYPE-C plug into the socket 10 of the TYPE-C socket 1, improving the operation convenience, and increasing the aesthetic feeling and interest at the same time.

[0045] Certainly, the above are only specific embodiments of the present utility model, and are not intended to limit the scope of implementation of the present utility model. Any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present utility model should be included in the scope of the patent application of the present utility model.
