Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, specifically to a connector anti-breakage protection device and a connector. Background Technology

[0002] A connector is an electronic component used to connect to electronic devices and enable the transmission of electrical energy and data. Existing connectors, such as Lightning connectors, generally have connecting parts and circuit boards. The connecting parts are mainly used for physical connection of electronic devices, while the circuit board is used for signal processing and transmission. The two work together to enable the transmission of electrical energy and data.

[0003] However, in existing connectors, since the connector and the circuit board are connected separately, there is a tendency for the connection to be unstable. This means that if one of the connector or the circuit board is subjected to force during use, it will tend to move relative to the other. Over time, this can easily lead to deformation or even breakage at the connection point, which greatly affects the lifespan of the connector.

[0004] Based on this, the present invention aims to provide a solution to address the problems existing in the prior art. Utility Model Content

The annular shell is sleeved on the circuit board. The interior of the first protective shell is connected to the interior of the annular shell through the connecting shell.

[0010] The ring-shaped shell can surround the circuit board 360°, providing excellent protection for the circuit board.

[0011] In one specific embodiment, at least a portion of the edge of the annular shell on the side away from the connecting shell extends in a direction away from the connecting shell to form a reinforcing shell sleeved on the circuit board.

[0012] The reinforced shell design further enhances the bending resistance between the connector and the circuit board.

[0013] In one specific embodiment, the cross-section of the reinforcing shell is U-shaped, and / or the total length of the reinforcing shell and the annular shell is between 7.0 mm and 7.5 mm.

[0014] In one specific embodiment, the height of the connecting shell is greater than that of the first protective shell, so as to form an abutment wall on the side of the connecting shell facing the first protective shell.

[0015] The abutment wall can act as a stop and limit when the connector is plugged into an external device, thus improving the user experience.

[0016] In one specific embodiment, both the first protective shell and the second protective shell are provided with cushioning components inside, and the connector and the circuit board are both wrapped by the cushioning components.

[0017] In one specific embodiment, the first protective shell has a notch for the pins of the connector to be exposed, and a portion of the pins is wrapped by a buffer, which engages with the inner wall of the first protective shell.

[0018] In one specific embodiment, a buffer member located in the second protective shell is engaged with the second protective shell, and the buffer member has an abutting portion that abuts against the side of the second protective shell away from the first protective shell.

[0019] In one specific embodiment, the thickness of the first protective shell ranges from 0.15 mm to 0.25 mm, and / or the thickness of the second protective shell ranges from 0.2 mm to 0.4 mm.

[0020] A second aspect of this utility model is to provide a connector including the connector anti-breakage protection device described in any of the above embodiments.

[0021] This utility model has at least the following beneficial effects:

[0022] This utility model discloses a connector anti-breakage protection device and a connector.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] In existing connectors, the connecting parts and the circuit board are not adequately protected, making them highly susceptible to deformation and breakage, resulting in a short connector lifespan. Therefore, this invention provides a connector anti-breakage protection device and connector. The device protects the connector from deformation and breakage of the connecting parts and the circuit board. The following provides a detailed description of the connector anti-breakage protection device and connector of this invention.

[0038] Please refer to Figures 1 to 4 This utility model provides a connector anti-breakage protection device, including: a first protective shell 1 and a second protective shell 2.

[0039] Specifically, the first protective shell 1 and the second protective shell 2 are fixedly connected, and the interiors of the first protective shell 1 and the second protective shell 2 are connected. The first protective shell 1 is sleeved on the connector 31 of the external connector 3, and the second protective shell 2 is sleeved on the circuit board 32 of the external connector 3, which is used to restrict relative movement between the connector 31 and the circuit board 32, thereby preventing the connector 31 and the circuit board 32 from breaking.

[0040] Understandably, since the first protective shell 1 and the second protective shell 2 are respectively fitted onto the connector 31 and the circuit board 32, and the first protective shell 1 and the second protective shell 2 are fixedly connected, when one of the connector 31 and the circuit board 32 is subjected to force and has a tendency to move, the other will be driven to have the same tendency to move through the protective shell, thereby restricting the relative movement between the connector 31 and the circuit board 32, thereby preventing the connector 31 and the circuit board 32 from breaking.

[0041] Optionally, the first protective shell 1 and the second protective shell 2 can be integrally formed, or they can be fixedly connected by welding, or they can be detachably fixedly connected by other means such as snap-fit ​​connection. No specific limitation is made in this regard.

[0042] Optionally, the first protective shell 1 may completely cover the connector 31, or it may only cover a portion of the connector 31. Similarly, the second protective shell 2 may completely cover the circuit board 32, or it may only cover a portion of the circuit board 32.

[0043] Furthermore, the first protective shell 1 can be sleeved on the connector 31 in such a way that its inner wall directly contacts the connector 31, or it can be sleeved on the connector 31 in a way that it indirectly contacts the connector 31 through other components. Similarly, the second protective shell 2 can also be sleeved on the circuit board 32 in such a way that its inner wall directly contacts the circuit board 32, or it can be sleeved on the circuit board 32 in a way that it indirectly contacts the circuit board 32 through other components.

[0044] Optionally, the first protective shell 1 and the second protective shell 2 can be metal shells, alloy shells, plastic shells, or shells of other materials, without specific limitations. For example, both the first protective shell 1 and the second protective shell 2 can be aluminum alloy shells.

[0045] In one specific embodiment, please refer to Figure 1 and Figure 2 The second protective shell 2 may include a connecting shell 21 and an annular shell 22.

[0046] Specifically, the first protective shell 1 is fixedly connected to one side of the connecting shell 21, and the annular shell 22 is fixedly connected to the other edge of the connecting shell 21. The annular shell 22 is fitted onto the circuit board 32, providing 360° coverage. The interior of the first protective shell 1 is connected to the interior of the annular shell 22 via the connecting shell 21.

[0047] Optionally, the cross-section of the annular shell 22 can be circular, elliptical, polygonal, irregular annular, or other shapes that can achieve 360° enclosure.

[0048] In one embodiment, the height of the connecting shell 21 is greater than that of the first protective shell 1, so that an abutment wall 211 is formed on the side of the connecting shell 21 facing the first protective shell 1. This abutment wall 211 can be used to abut against the external device when the connector 31 is plugged into it, thereby limiting the plugging between the connector 31 and the external device. Exemplarily, the connecting shell 21 and the first protective shell 1 may form a 90° angle.

[0049] Furthermore, at least a portion of the edge of the annular shell 22 on the side away from the connecting shell 21 can extend further away from the connecting shell 21, thereby forming a reinforcing shell 23 fitted onto the circuit board 32. Preferably, the annular shell 22 and the reinforcing shell 23 are integrally formed. Understandably, by lengthening the annular shell 22 with the reinforcing shell 23, the bending resistance between the protected connector 31 and the circuit board 32 can be further improved.

[0050] For example, please refer to again Figure 2 The reinforcing shell 23 can extend from a portion of the edge of the annular shell 22 away from the connecting shell 21 in a direction away from the connecting shell 21, so that the connecting shell 21, the annular shell 22 and the reinforcing shell 23 together form an L-shaped structure.

[0051] In one specific embodiment, please refer to Figure 4 The reinforcing shell 23 has a U-shaped cross-section, allowing its opposite sides to be fastened to the circuit board 32, thus improving the protection of the circuit board 32. Additionally, refer to... Figure 2 The total length d of the reinforcing shell 23 and the annular shell 22 can be between 7.0 mm and 7.5 mm, for example, it can be 7.3 mm.

[0052] In one specific embodiment, the thickness h1 of the first protective shell 1 ranges from 0.15 mm to 0.25 mm, for example, it can be 0.22 mm. The thickness h2 of the second protective shell 2 ranges from 0.2 mm to 0.4 mm, for example, it can be 0.3 mm.

[0053] In one specific embodiment, please refer to Figure 1 and Figure 3 Both the first protective shell 1 and the second protective shell 2 are provided with a buffer 4 inside. The connector 31 and the circuit board 32 are both wrapped by the buffer 4. That is, the first protective shell 1 is fitted onto the connector 31 by the buffer 4, and the second protective shell 2 is fitted onto the circuit board 32 by the buffer 4.

[0054] For example, the buffer 4 can be an injection molded part. In practical applications, after the first protective shell 1 and the second protective shell 2 are fitted onto the connector 31 and the circuit board 32, injection molding is performed inside the first protective shell 1 and the second protective shell 2, so that the connector 31 and the circuit board 32 are wrapped by the injection molded part.

[0055] Furthermore, the first protective shell 1 may have a notch 11 for exposing the pin 311 of the connector 31. The number of notches 11 may be one or more. Part of the pin 311 is covered by the buffer 4. Specifically, please refer to Figure 3 One side of the pin 311 is exposed through the buffer 4 and through the notch 11 to the outside for connection with external devices.

[0056] The buffer 4 can be engaged with the inner wall of the first protective shell 1. For example, please refer to Figure 1 The inner wall of the first protective shell 1 may have a locking protrusion 12, and the buffer 4 is provided with a corresponding locking groove 41. The first protective shell 1 and the buffer 4 are connected by locking the locking protrusion 12 and locking the groove 41.

[0057] In one specific embodiment, please refer to Figure 3 and Figure 4 The buffer member 4 located in the second protective shell 2 is also engaged with the second protective shell 2. Exemplarily, in an embodiment including a reinforcing shell 23 with a "U" shaped cross-section, grooves 231 may be formed on the inner walls of opposite sides of the reinforcing shell 23, and a protrusion 42 is provided on the buffer member 4 at the position corresponding to the groove 231. The groove 231 and the protrusion 42 cooperate to engage the buffer member 4 with the reinforcing shell 23.

[0058] Additionally, please refer to Figure 1The buffer 4 may have an abutting portion 43, which abuts against the side of the second protective shell 2 away from the first protective shell 1. Exemplarily, the extending direction of the slot 231 may be the same as the direction in which the buffer 4 enters and exits the interior of the second protective shell 2. During the process of the buffer 4 entering the interior of the second protective shell 2, the protrusion 42 slides and engages with the slot 231. Finally, when the abutting portion 43 abuts against the side of the second protective shell 2 away from the first protective shell 1, the buffer 4 is installed.

[0059] This utility model also provides a connector, including the connector anti-breakage protection device described in any of the above embodiments.

[0060] For example, please refer to Figure 1 Connector 3 can be a Lightning male connector, which includes a connecting piece 31 and a circuit board 32. The connecting piece 31 can be a metal connecting plate with pins 311. A first protective shell 1 is fitted onto the connecting piece 31, and a second protective shell 2 is fitted onto the circuit board 32, making it less prone to deformation and breakage between the connecting piece 31 and the circuit board 32.

[0061] In other embodiments, connector 3 may also be other types of male or female connectors, without specific limitation. In embodiments where connector 3 is a female connector, the female connector's connecting element 31 may be a pin, which is connected to the circuit board. A first protective shell 1 is fitted onto the pin, and a second protective shell 2 is fitted onto the circuit board, making it less prone to deformation and breakage between the pin and the circuit board.

[0062] In summary, the present invention provides a connector anti-breakage protection device and a connector, wherein the connector anti-breakage protection device can limit the relative movement between the connector 31 and the circuit board 32 through the connected first protective shell 1 and second protective shell 2, thereby preventing deformation and breakage of the connector 31 and the circuit board 32, and improving the service life of the connector 3.

[0063] Furthermore, the second protective shell 2 may include a connecting shell 21, an annular shell 22, and a reinforcing shell 23, which together can form an "L" shape, thereby further improving the bending resistance between the connector 31 and the circuit board 32.

[0064] The connector of this utility model, based on the anti-breakage protection device, makes it less prone to deformation and breakage between the connector 31 and the circuit board 32, resulting in a good user experience and service life.
