Generally, the electronic devices are equipped with charging devices, and the charging devices are provided with charging connectors. The charging connectors are plugged into the electronic devices, so that the electronic devices can be charged. In the related art, the charging connectors are provided with multiple pins, and the multiple pins include voltage pins, signal pins and the like. However, in the related art, the charging connectors are prone to electrocorrosion. CONTENT OF THE UTILITY MODEL

[0003] The application aims to provide a charging connector and a charging device, and at least solve the problem that the charging connector is prone to electrocorrosion.

[0004] In a first aspect, the application provides a charging connector, which comprises a connector body, a voltage pin, a first signal pin, a second signal pin and a third signal pin.

[0006] The two ends of the metal part exposed on the surface of the connector body of the first signal pin are not flush with the two ends of the metal part exposed on the surface of the connector body of the second signal pin.

[0010] The charging device is used for charging the device body.

[0011] In the embodiment of the present application, since the voltage pin, the first signal pin, the second signal pin and the third signal pin are sequentially and spacedly distributed along the first direction, the voltage pin and the first signal pin have a gap, the first signal pin and the second signal pin have a gap, and the second signal pin and the third signal pin have a gap. Since the first signal pin is not flush with the second signal pin at the two ends of the metal part exposed on the surface of the connector body, it is equivalent to that the gap between the first signal pin and the voltage pin is increased at the positions where the two ends of the first signal pin are not flush with the two ends of the second signal pin, that is, the gap between the voltage pin and the first part of the first signal pin not only includes the original gap width, but also includes the width of the first signal pin, so that the gap between the first signal pin and the voltage pin is increased, thereby effectively avoiding the problem of easy electrocorrosion of the voltage pin and the first signal pin. That is, in the embodiment of the present application, by arranging the first signal pin not to be flush with the second signal pin at the two ends of the metal part exposed on the surface of the connector body, the probability of easy electrocorrosion of the voltage pin and the first signal pin can be effectively reduced, thereby effectively protecting the charging connector and prolonging the service life of the charging connector.

Figures 1 to 5 As shown in FIG. 1, the charging connector includes a connector body 10, a voltage pin 101, a first signal pin 102, a second signal pin 103, and a third signal pin 104.

[0023] The voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are arranged on the surface of the connector body 10, and the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are sequentially and spacedly arranged along a first direction X. The two ends of the metal part of the first signal pin 102 exposed on the surface of the connector body 10 are not flush with the two ends of the metal part of the second signal pin 102 exposed on the surface of the connector body 10.

[0024] In the embodiment of the present application, since the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are sequentially and spacedly arranged along the first direction X, there is a gap between the voltage pin 101 and the first signal pin 102, a gap between the first signal pin 102 and the second signal pin 103, and a gap between the second signal pin 103 and the third signal pin 104. Since the two ends of the metal part of the first signal pin 102 exposed on the surface of the connector body 10 are not flush with the two ends of the metal part of the second signal pin 102 exposed on the surface of the connector body 10, it is equivalent to that the two ends of the first signal pin 102 are not flush with the two ends of the second signal pin 103 at the position, so that the gap between the first signal pin 102 and the voltage pin 101 is increased, that is, the gap between the voltage pin 101 and the first part 1021 of the first signal pin 102 not only includes the original gap width, but also includes the width of the first signal pin 102, thereby increasing the gap between the first signal pin 102 and the voltage pin 101, so that the problem of easy electrocorrosion of the voltage pin 101 and the first signal pin 102 can be effectively avoided. That is, in the embodiment of the present application, by arranging the two ends of the metal part of the first signal pin 102 exposed on the surface of the connector body 10 not flush with the two ends of the metal part of the second signal pin 102 exposed on the surface of the connector body 10, the probability of easy electrocorrosion of the voltage pin 101 and the first signal pin 102 can be effectively reduced, so that the charging connector can be effectively protected, and the service life of the charging connector is prolonged.

[0025] It should be noted that in the embodiments of the present application, the charging connector can be a Type-C connector, the voltage pin 101 can be a Vbus pin, the first signal pin 102 can be a CC pin, the second signal pin 103 can be a D+ pin, and the second signal pin 103 can be a D- pin.

[0026] In addition, in the embodiments of the present application, the connector body 10 can be formed of a plastic material, and of course, the connector body 10 can also be formed of a plastic material, and the present application does not limit this. In addition, the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 can all be formed of a conductive material, for example, the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are all formed of copper, and for another example, the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are all formed of silver. The present application does not limit this.

[0027] In addition, in some embodiments, the first signal pin 102 includes a first portion 1021 and a second portion 1022, the first portion 1021 is connected to the second portion 1022, the surface of the first portion 1021 is covered with an insulating material, and the second portion 1022 is conductive, and the second signal pin 102 is not covered with an insulating material.

[0028] Since the surface of the first portion 1021 of the first signal pin 102 is covered with an insulating material and the second signal pin 102 is not covered with an insulating material, at the first portion 1021 of the first signal pin 102, the gap between the first signal pin 102 and the voltage pin 101 is increased, that is, the gap between the voltage pin 101 and the first portion 1021 of the first signal pin 102 not only includes the original gap width, but also includes the width of the first signal pin 102, thereby increasing the gap between the first signal pin 102 and the voltage pin 101, thereby effectively avoiding the problem of easy electrocorrosion of the voltage pin 101 and the first signal pin 102. That is, by covering the surface of the first portion 1021 of the first signal pin 102 with an insulating material, the probability of electrocorrosion of the voltage pin 101 and the first signal pin 102 can be effectively reduced, thereby effectively protecting the charging connector and prolonging the service life of the charging connector.

[0029] In addition, in the embodiments of the present application, the length of the first signal pin 102 can be less than the length of the second signal pin 103, at this time, neither the first signal pin 102 nor the second signal pin 103 is covered with an insulating material.

[0030] Furthermore, in this embodiment of the present application, the first portion 1021 is embedded within the connector body 10, which is insulated, so that the surface of the first portion 1021 is covered with an insulating material. This makes the first portion 1021 non-conductive, effectively increasing the gap between the first signal pin 102 and the voltage pin 101 at the first portion 1021, effectively reducing the likelihood of electrical corrosion between the voltage pin 101 and the first signal pin 102. Furthermore, embedding the first portion 1021 within the connector body 10 avoids the need for additional insulating material, thereby reducing the cost of the charging connector.

[0031] Of course, in the embodiment of the present application, an insulating material may be directly coated on the surface of the first portion 1021, which is equivalent to directly forming an insulating layer on the surface of the first portion 1021. This embodiment of the present application does not limit this.

[0032] Additionally, in some embodiments, Figure 1 As shown, a fixing platform 11 is provided on the connector body 10. One end of the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are all fixed to the fixing platform 11. The voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 all extend along a second direction Y, which intersects the first direction X. One end of the first portion 1021 is connected to the fixing platform 11, and the other end of the first portion 1021 is connected to the first portion 1021.

[0033] Since one end of the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 are fixed to the fixed platform 11, by setting the fixed platform 11, it can be ensured that the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 are not easy to separate from the connector body 10. Since the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 all extend along the second direction Y, the gap between the voltage pin 101 and the first signal pin 102 is easy to accumulate water or foreign matter at the fixed platform 11, the gap between the first signal pin 102 and the second signal pin 103 is easy to accumulate water or foreign matter at the fixed platform 11, and the gap between the second signal pin 103 and the third signal pin 104 is easy to accumulate water or foreign matter at the fixed platform 11. Since one end of the first part 1021 of the first signal pin 102 is connected with the fixed platform 11, and the other end of the first part 1021 is connected with the second part 1022, it is equivalent that the first part 1021 of the first signal pin 102 is close to the fixed platform 11, and the second part 1022 of the first signal pin 102 is away from the fixed platform 11, and the first part 1021 is buried in the connector body 10, which is equivalent to making the gap between the first signal pin 102 and the voltage pin 101 not easy to accumulate water or foreign matter at the fixed platform 11, thereby avoiding the problem that the voltage pin 101 and the first signal pin 102 are easy to be electrically corroded.

[0034] In the related art, the charging connector also includes a connector body 10, a voltage pin 101, a first signal pin 102, a second signal pin 103 and a third signal pin 104, the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 are sequentially and spacedly distributed on the connector body 10 along a first direction X, and a fixed platform 11 is arranged on the connector body 10, and the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 are all connected to the fixed platform 11. Through such a setting, the gap between the voltage pin 101 and the first signal pin 102 is easy to accumulate water or foreign matter at the fixed platform 11, which leads to the problem that the voltage pin 101 and the first signal pin 102 are easy to be electrically corroded. In the embodiment of the present application, the first part 1021 of the first signal pin 102 is buried in the connector body 10, which is equivalent to changing the shape of the first signal pin 102 exposed to the connector body 10, and making the gap between the first signal pin 102 and the voltage pin 101 not easy to accumulate water or foreign matter at the fixed platform 11, thereby avoiding the problem that the voltage pin 101 and the first signal pin 102 are easy to be electrically corroded.

[0035] In addition, in some embodiments, the voltage difference between any two of the first signal pin 102, the second signal pin 103, and the third signal pin 104 is M, satisfying: 0 < M < 3.3 V.

[0036] Since the first signal pin 102, the second signal pin 103, and the third signal pin 104 are prone to electrocorrosion not only because of water accumulation or foreign matter, but also because of the voltage, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are prone to electrocorrosion. Therefore, in the embodiments of the present application, by setting the voltage difference between any two of the first signal pin 102, the second signal pin 103, and the third signal pin 104 to satisfy: 0 < M < 3.3 V, the voltage difference between any two of the first signal pin 102, the second signal pin 103, and the third signal pin 104 is reduced, thereby reducing the probability of electrocorrosion of the first signal pin 102, the second signal pin 103, and the third signal pin 104. That is, by setting the voltage difference between any two of the first signal pin 102, the second signal pin 103, and the third signal pin 104 to M, satisfying: 0 < M < 3.3 V, the charging connector can be protected, and the probability of electrocorrosion of the first signal pin 102, the second signal pin 103, and the third signal pin 104 can be reduced.

[0037] In addition, the voltage difference between any two of the first signal pin 102, the second signal pin 103, and the third signal pin 104 is M, that is, the voltage difference between the first signal pin 102 and the third signal pin 104 is M, or the voltage difference between the second signal pin 103 and the third signal pin 104 is M, or the voltage difference between the second signal pin 103 and the first signal pin 102 is M. In addition, M can be any value greater than 0 and less than 3.3 V, for example, the voltage of the second signal pin 103 is 2 V, and the voltage of the third signal pin 104 is 3.5 V, so the voltage difference M between the second signal pin 103 and the third signal pin 104 is 1.5 V, and for another example, the voltage of the second signal pin 103 is 2 V, and the voltage of the third signal pin 104 is 4.5 V, so the voltage difference M between the second signal pin 103 and the third signal pin 104 is 2.5 V. For this, the embodiments of the present application are not limited herein.

[0038] In addition, in some embodiments, in each transmission cycle of the signal, the duty cycle of the first signal pin 102, the second signal pin 103, and the third signal pin 104 transmitting the signal is N, satisfying: 0 < N < 100%.

[0039] Since the first signal pin 102, the second signal pin 103, and the third signal pin 104 are susceptible to electrical corrosion not only due to accumulated water or foreign matter but also due to the influence of voltage, in the embodiment of the present application, by setting the duty cycle of the first signal pin 102, the second signal pin 103, and the third signal pin 104 transmitting signals to N in each transmission cycle of the signal transmission, the duty cycle satisfies: 0<N<100%. Therefore, when the first signal pin 102, the second signal pin 103, and the third signal pin 104 transmit signals, the voltage difference between the first signal pin 102, the second signal pin 103, and the third signal pin 104 is small, which can help reduce the probability of electrical corrosion of the first signal pin 102, the second signal pin 103, and the third signal pin 104.

[0040] It should be noted that, in the embodiment of the present application, 0<M<3.3V and 0<N<100% can be set, or only 0<M<3.3V or 0<N<100% can be set. This embodiment of the present application does not limit this.

[0041] Additionally, in some embodiments, Figure 3 and Figure 4 As shown, the third signal pin 104 includes a third portion 1041 and a fourth portion 1042 . The third portion 1041 is connected to the fourth portion 1042 . The surface of the third portion 1041 is covered with an insulating material, and the fourth portion 1042 is conductive.

[0042] Because the third portion 1041 of the third signal pin 104 is buried in the connector body 10, the gap between the third signal pin 104 and the second signal pin 103 is increased at the third portion 1041 of the third signal pin 104. That is, the gap between the second signal pin 103 and the third portion 1041 of the third signal pin 104 includes not only the original gap width but also the width of the third signal pin 104. This increases the gap between the third signal pin 104 and the second signal pin 103, thereby effectively preventing the problem of electrical corrosion between the second signal pin 103 and the third signal pin 104. That is, in the embodiment of the present application, by burying the third portion 1041 of the third signal pin 104 in the connector body 10, the probability of electrical corrosion between the second signal pin 103 and the third signal pin 104 is effectively reduced, thereby effectively protecting the charging connector and extending its service life.

[0043] Furthermore, in this embodiment of the present application, the third portion 1041 is embedded within the connector body 10, which is insulated, so that the surface of the third portion 1041 is covered with an insulating material. This makes the third portion 1041 non-conductive, effectively increasing the gap between the second signal pin 103 and the third signal pin 104 at the third portion 1041, effectively reducing the risk of electrical corrosion between the second signal pin 103 and the third signal pin 104. Furthermore, embedding the third portion 1041 within the connector body 10 avoids the need for additional insulating material, thereby reducing the cost of the charging connector.

[0044] Of course, in the embodiment of the present application, an insulating material may be directly coated on the surface of the third portion 1041, which is equivalent to directly forming an insulating layer on the surface of the third portion 1041. This embodiment of the present application does not limit this.

[0045] Additionally, in some embodiments, Figure 3 As shown, a fixing platform 11 is provided on the connector body 10. One end of the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are all fixed to the fixing platform 11. The voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 all extend along the second direction Y, which intersects the first direction X. One end of the third portion 1041 is connected to the fixing platform 11, and the other end of the third portion 1041 is connected to the first portion 1021.

[0046] Because one end of the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are all fixed to the fixing platform 11, the fixing platform 11 can ensure that the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 are not easily detached from the connector body 10. Because the voltage pin 101, the first signal pin 102, the second signal pin 103, and the third signal pin 104 all extend along the second direction Y, the gap between the voltage pin 101 and the first signal pin 102 is prone to water accumulation or foreign matter accumulation on the fixing platform 11, the gap between the first signal pin 102 and the second signal pin 103 is prone to water accumulation or foreign matter accumulation on the fixing platform 11, and the gap between the second signal pin 103 and the third signal pin 104 is prone to water accumulation or foreign matter accumulation on the fixing platform 11. Because one end of the third portion 1041 of the third signal pin 104 is connected to the fixing platform 11, and the other end of the third portion 1041 is connected to the fourth portion 1042, the third portion 1041 of the third signal pin 104 is close to the fixing platform 11, while the fourth portion 1042 of the third signal pin 104 is away from the fixing platform 11. The third portion 1041 is buried in the connector body 10. This makes it difficult for water or foreign matter to accumulate in the gap between the third signal pin 104 and the second signal pin 103 on the fixing platform 11, thereby preventing the third signal pin 104 and the second signal pin 103 from easily corroding.

[0047] Additionally, in some embodiments, Figure 5 As shown, the length of the voltage pin 101 is smaller than the length of the first signal pin 102. The length of the voltage pin 101 is: the distance between the two opposite ends of the voltage pin 101 in the second direction Y, and the length of the first signal pin 102 is: the distance between the two opposite ends of the first signal pin 102 in the second direction Y.

[0048] Because the length of the voltage pin 101 is shorter than that of the first signal pin 102, the voltage pin 101 and the first signal pin 102 are partially offset in the second direction Y. That is, the projection of the voltage pin 101 partially overlaps the projection of the first signal pin 102 in the second direction Y. This reduces the relative area between the first signal pin 102 and the voltage pin 101, which helps reduce the probability of electrical corrosion between the first signal pin 102 and the voltage pin 101. Specifically, by setting the length of the voltage pin 101 to be shorter than that of the first signal pin 102, the charging connector is protected, further reducing the probability of electrical corrosion between the first signal pin 102 and the voltage pin 101.

[0049] It should be noted that in the embodiment of the present application, the length of the voltage pin 101 is less than the length of the first signal pin 102, which is equivalent to shortening the length of the voltage pin 101, that is, compared with the voltage pin 101 in the related art, the length of the voltage pin 101 is shortened in the present application, wherein the shortening range of the voltage pin 101 is 0% to 50%.

[0050] For example, as shown in Figure 5 , the length of the voltage pin 101 can be L1, and the length of the first signal pin 102 can be L2, L1 < L2.

[0051] In addition, in some embodiments, the length of the second signal pin 103 is less than the length of the first signal pin 102, and the length of the second signal pin 103 is the distance between the two opposite ends of the second signal pin 103 in the second direction Y, and the length of the first signal pin 102 is the distance between the two opposite ends of the first signal pin 102 in the second direction Y.

[0052] Since the length of the second signal pin 103 is less than the length of the first signal pin 102, it is equivalent to that the second signal pin 103 is partially misaligned with the first signal pin 102 in the second direction Y, that is, the projection of the second signal pin 103 partially overlaps with the projection of the first signal pin 102 in the second direction Y, thereby reducing the relative area between the first signal pin 102 and the second signal pin 103, which is beneficial to reduce the probability of electrical corrosion of the first signal pin 102 and the second signal pin 103. That is, by setting the length of the second signal pin 103 to be less than the length of the first signal pin 102, the charging connector can be protected, and the probability of electrical corrosion of the first signal pin 102 and the second signal pin 103 can be further reduced.

[0053] It should be noted that in the embodiment of the present application, the length of the second signal pin 103 is less than the length of the first signal pin 102, which is equivalent to shortening the length of the second signal pin 103, that is, compared with the second signal pin 103 in the related art, the length of the second signal pin 103 is shortened in the present application, wherein the shortening range of the second signal pin 103 is 0% to 50%.

[0054] For example, as shown in Figure 5 , the length of the second signal pin can be L3, and the length of the first signal pin 102 can be L2, L3 < L2.

[0055] In addition, in the embodiment of the present application, as shown in Figure 3 , when the fixed table 11 is arranged on the connector body 10, the second signal pin 103 can not be connected to the fixed table 11.

[0056] It should be noted that in the embodiment of the present application, the length of the second signal pin 103 can be less than the length of the first signal pin 102, and the length of the voltage pin 101 can be less than the length of the first signal pin 102, and the first part 1021 can be buried in the connector body 10, and the third part 1041 can be buried in the body, so that the probability of electrocorrosion of the signal pins on the connector body 10 can be further reduced.

[0057] In the embodiment of the present application, the voltage pin 101, the first signal pin 102, the second signal pin 103 and the third signal pin 104 are sequentially and spacedly arranged along the first direction X, so that there is a gap between the voltage pin 101 and the first signal pin 102, a gap between the first signal pin 102 and the second signal pin 103, and a gap between the second signal pin 103 and the third signal pin 104. Since the two ends of the first signal pin 102 exposed on the surface of the connector body 10 are not flush with the two ends of the second signal pin 102 exposed on the surface of the connector body 10, the gap between the first signal pin 102 and the voltage pin 101 is increased at the position where the two ends of the first signal pin 102 are not flush with the two ends of the second signal pin 103, that is, the gap between the voltage pin 101 and the first part 1021 of the first signal pin 102 not only includes the original gap width, but also includes the width of the first signal pin 102, so that the gap between the first signal pin 102 and the voltage pin 101 is increased, and the problem of easy electrocorrosion between the voltage pin 101 and the first signal pin 102 can be effectively avoided. That is, in the embodiment of the present application, by arranging the two ends of the signal pin 102 exposed on the surface of the connector body 10 to be not flush with the two ends of the second signal pin 102 exposed on the surface of the connector body 10, the probability of easy electrocorrosion between the voltage pin 101 and the first signal pin 102 can be effectively reduced, so that the charging connector can be effectively protected, and the service life of the charging connector can be prolonged.
