Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a connector used in vehicle-mounted smart gateways. Background Technology

[0002] In-vehicle smart gateway connectors often require high-power data transmission (due to their high processing frequency) to ensure efficient operation. However, this high-power transmission often generates significant heat at the terminals, and standard heat dissipation structures may not be able to adequately dissipate it, leading to data transmission delays and instability. Therefore, improving the connector's heat dissipation stability is a key design consideration.

[0003] The pins of this type of connector generally have a small diameter, so they are usually made using direct injection molding. Therefore, when the contact area between the plastic structure and the pin is small, it can easily affect the stability of the pin. Utility Model Content

[0004] The main purpose of this invention is to propose a connector for use in vehicle-mounted smart gateways, which aims to improve the structure of the plastic shell, ensuring structural stability between the terminals and the plastic shell, while also improving the heat dissipation stability of the PIN pins.

[0005] To achieve the above objectives, this utility model proposes a connector for use in vehicle-mounted smart gateways, comprising a plastic shell, PIN pins, and a heat dissipation groove. The plastic shell is provided with a insertion groove, and the PIN pins are distributed in at least two rows along the width direction. Each PIN pin includes an insertion rod extending into the insertion groove and a vertical rod bent and extending into the bottom wall of the plastic shell. The heat dissipation groove is recessed in the rear wall of the plastic shell and is located between two adjacent rows of PIN pins and extends forward.

[0006] Unlike existing heat dissipation structures, this design improves the heat dissipation area of ​​the plastic shell by recessing heat dissipation grooves between adjacent rows of pins, thereby enhancing the heat dissipation effect of the pins. The recessed structure also reduces the distance between the pins and the outer wall of the plastic shell, further improving the heat dissipation effect. Attached Figure Description

[0023] like Figures 1 to 5 As shown, a connector used in an in-vehicle smart gateway includes:

[0024] Plastic shell 1, wherein the plastic shell 1 is provided with a insertion groove 10;

[0025] PIN pin 2, the PIN pin 2 is distributed in at least two rows along the width direction, the PIN pin 2 includes a plug rod 21 that extends into the plug groove 10 and a vertical rod 22 that is bent and extends into the bottom wall of the plastic shell 1;

[0026] The heat dissipation groove 31 is recessed in the rear wall of the plastic shell 1 and is located between two adjacent rows of PIN pins 2 and extends forward.

[0027] Unlike existing heat dissipation structures, by improving the structure of the plastic shell 1, the heat dissipation groove 31 is recessed between two adjacent rows of PIN pins 2, thereby increasing the heat dissipation area of ​​the plastic shell 1 and improving the heat dissipation effect of the PIN pins 2. In addition, the recessed structure can also reduce the distance between the PIN pins 2 and the outer wall of the plastic shell 1, thereby improving the heat dissipation effect.

[0028] Specifically, the heat dissipation groove 31 extends in an arc shape, which facilitates the demolding of the plastic shell 1 during injection molding. At the same time, the arc-shaped heat dissipation groove 31 can also make the structure of the plastic shell 1 more stable. In addition, the rear end of the plastic shell 1 at the PIN pin 2 will also form an arc-shaped rib 32, thereby improving the structural strength.

[0029] In this embodiment of the present invention, the plastic shell 1 is provided with an arc-shaped rib 32 at the rear end of the PIN pin 2, which increases the heat dissipation area without affecting the structural strength of the plastic shell 1.

[0030] Specifically, the PIN pins 2 are arranged in at least two columns along the height position, and there are pivot points between the two adjacent columns and two rows of PIN pins 2. The pivot points are provided with guide posts 4. The setting of guide posts 4 can ensure the coaxiality of the male head when it is inserted into the insertion slot 10, thereby ensuring the stability of the insertion between the male head and the female head.

[0031] In this embodiment of the utility model, the guide post 4 is in the shape of a cross, thereby ensuring the coaxiality of the male head during insertion and ensuring that the insertion rod 21 extends into the female terminal.

[0032] Of course, the specific guide post 4 can also be cylindrical or other shapes, thereby improving the insertion accuracy.

[0033] The front wall of the guide post 4 is longer than the front wall of the PIN pin 2 or is at the same horizontal plane l as the front wall of the PIN pin, and the front wall of the guide post is wedge-shaped, wherein the wedge shape can play a guiding role. At the same time, the length of the guide post is greater than the length of the PIN pin 2, which can reduce the force on the PIN pin 2 and improve its service life.

[0034] Specifically, the plastic shell 1 has a locking groove 5 on the upper wall of the insertion groove 10, wherein the locking groove 5 is used to cooperate with the corresponding locking device (e.g., a buckle) when the male head is inserted into the insertion groove 10, thereby realizing the locking between the female head and the male head.

[0035] In this embodiment of the invention, the bottom wall of the plastic shell 1 is provided with a horizontally extending positioning plate 6, and the lower wall of the positioning plate 6 is provided with a positioning cavity 60.

[0036] The positioning cavity 60 is used to install the baffle 7, and the vertical rod 22 cooperates with the baffle 7. The positioning cavity 60 facilitates the installation and fixation of the baffle 7.

[0037] A PCB board is installed between the baffle and the top wall of the positioning cavity. The baffle is used to limit and protect the PCB board.

[0038] Specifically, the positioning piece 61 extends inward from the inner wall of the middle part of the positioning cavity 60, and the baffle 7 is provided with a slot 70 that cooperates with the positioning plate 6, thereby realizing the limiting and positioning of the baffle 7 and facilitating its installation.

[0039] In this embodiment of the invention, the plastic shell 1 and the positioning plate 6 are integrally formed, and the plastic shell 1 and the PIN pin 2 are integrally injection molded, thereby improving the structural strength of the connector.

[0040] Specifically, the positioning plate 6 has outwardly extending ears 62 on both sides, and the ears have through holes 63. The through holes facilitate the installation and fixation of the positioning plate 6.

[0041] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
