Description

Technical Field

[0001] This utility model belongs to the field of electrical connector technology, and in particular relates to a TYPE-C double-layer vertical board-end connector. Background Technology

[0002] Automotive TYPE-C board-end connectors play an important role in connecting automotive electronic devices. They are compact and multifunctional, capable of charging and transmitting power as well as being compatible with data transmission from various devices. They are widely used in connecting audio-visual equipment, storage devices, or other automotive devices.

[0003] However, existing automotive Type-C board connectors often employ a single-layer contact structure. While this structure can meet basic connection requirements under normal conditions, it is subject to continuous vibration during vehicle operation, especially on bumpy roads. This vibration significantly impacts the connection stability and reliability of single-layer contact automotive Type-C board connectors. The single-layer contact structure is prone to failure, leading to issues such as screen flickering or momentary disconnections. This can affect the normal operation of in-vehicle devices, potentially causing loss of driving image data or distracting the driver, thus posing a safety hazard.

[0004] Therefore, given the single-layer contact structure of existing automotive TYPE-C board-end connectors and its problems in vibration environments, further technical improvements are urgently needed to adapt to vibration environments and ensure the continuity of signal transmission and the normal operation of the equipment. Utility Model Content

[0005] The purpose of this invention is to provide a TYPE-C double-layer vertical board-end connector to address the shortcomings of existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A TYPE-C double-layer vertical board-end connector includes: a plastic body, a metal shell, and a conductive terminal assembly. The plastic body includes an upper insulating base and a lower insulating base. An upper terminal retainer is mounted on the upper insulating base, and a lower terminal retainer is mounted on the lower insulating base. The metal shell covers the outer surface of the plastic body, and its rear end extends to form a plurality of solder feet for soldering and fixing to a circuit board. The conductive terminal assembly includes an upper row of conductive terminals embedded in the upper terminal retainer and a lower row of conductive terminals embedded in the lower terminal retainer. Each conductive terminal of the upper row and the lower row has two electrical contact surfaces, one upper and one lower.

[0008] Furthermore, a shielding partition is provided between the upper insulating base and the lower insulating base.

[0009] Furthermore, the lower surface of the upper insulating base and the upper surface of the lower insulating base are provided with positioning pins, and correspondingly, the shielding partition, the lower surface of the upper insulating base and the upper surface of the lower insulating base are provided with positioning holes that cooperate with the positioning pins.

[0010] Furthermore, grounding plates are respectively provided on the upper surface of the upper insulating base and the lower surface of the lower insulating base.

[0011] Furthermore, the grounding plate is stamped with elastic protrusions that make electrical contact with the metal casing.

[0012] Furthermore, the upper row of conductive terminals includes several first conductive terminals with equal spacing, which are fixed in the upper terminal retainer by an insert injection molding process; the lower row of conductive terminals includes the same number of second conductive terminals with equal spacing as the first conductive terminals, which are fixed in the lower terminal retainer by an insert injection molding process.

[0013] Furthermore, both the first conductive terminal and the second conductive terminal include a terminal body, a welding portion, and a contact portion; the terminal body is embedded in the corresponding terminal retainer; the welding portion is located at the rear of the terminal body and is used for welding to the PCB board; the contact portion is formed by the outward folding and extension of the terminal body, and its upper and lower contact surfaces in the thickness direction respectively constitute an upper electrical contact surface and a lower electrical contact surface.

[0014] Compared with the prior art, the beneficial technical effects of this TYPE-C double-layer vertical board-end connector provided by this utility model are as follows:

[0015] 1. This utility model uses a shielding partition between the upper and lower insulating base layers to block electromagnetic interference, and further enhances the shielding effectiveness by using a grounding plate covering the outer surface of the plastic body to form a continuous grounding loop through contact with the metal shell.

[0016] 2. This utility model achieves redundant contact by transforming a single-layer, single-contact structure into a double-layer, double-contact structure. When a single contact point momentarily disconnects due to vibration, the other contact point can still maintain an effective electrical connection, significantly improving the resistance to mechanical shock. It also compensates for defects such as screen flickering or momentary disconnection that occur after a single contact point fails when using a single-layer plug-in connection, thus significantly improving the stability and reliability of the connection.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] This utility model embodiment provides a TYPE-C double-layer vertical board-end connector, including a plastic body 1, a metal shell 4, and a conductive terminal assembly, specifically:

[0028] like Figures 1 to 5 As shown, in this embodiment, the plastic body 1 includes an upper insulating base 101 and a lower insulating base 102. The upper insulating base 101 is equipped with an upper terminal retainer 103, and the lower insulating base 102 is equipped with a lower terminal retainer 104. A shielding partition 2 is provided between the upper insulating base 101 and the lower insulating base 102 to block high-frequency crosstalk between adjacent terminals of the upper and lower layers, ensure the independence of dual-channel signal transmission, meet the integrity requirements of USB Type-C high-speed data transmission, and at the same time serve as an interlayer skeleton to enhance the overall mechanical strength.

[0029] The lower surface of the upper insulating base 101 and the upper surface of the lower insulating base 102 are also provided with positioning pins 105. Correspondingly, the shielding partition 2, the lower surface of the upper insulating base 101 and the upper surface of the lower insulating base 102 are provided with positioning holes 201 that cooperate with the positioning pins 105 to ensure accurate assembly and positioning between the layers.

[0030] In a preferred embodiment, the upper surface of the upper insulating base 101 and the lower surface of the lower insulating base 102 are respectively covered with grounding plates 3. The grounding plates 3 are stamped with elastic protrusions 301 that make electrical contact with the metal casing 4. Through the elastic contact between the grounding plates 3 and the metal casing 4, a continuous grounding loop is formed, further enhancing the electromagnetic shielding effectiveness.

[0031] The metal shell 4 is tightly fitted onto the plastic body 1 with a certain interference fit, so that the metal shell 4 completely covers the outer surface of the plastic body 1. The fastening connection is achieved by the friction and clamping force generated by the interference fit between the two, which improves the structural strength of the connector, protects the conductive terminal components inside the connector, and prevents external physical damage and electromagnetic interference. The rear end of the metal shell 4 extends to form multiple solder feet 401, which are soldered and fixed to the circuit board.

[0032] The conductive terminal assembly includes an upper row of conductive terminals embedded in an upper terminal holder 103 and a lower row of conductive terminals embedded in a lower terminal holder 104. Both the upper and lower rows of conductive terminals are formed using a stamping and bending process, and each conductive terminal has two electrical contact surfaces, upper and lower. The upper row of conductive terminals includes several equally spaced first conductive terminals 5, which are fixed to the upper terminal holder 103 using an insert injection molding process. The lower row of conductive terminals includes the same number of equally spaced second conductive terminals 6 as the first conductive terminals 5, which are fixed to the lower terminal holder 104 using an insert injection molding process. Both the first conductive terminals 5 and the second conductive terminals 6 are integrally stamped and each includes a welding portion 503, a terminal body 501, and a contact portion 502.

[0033] Taking the first conductive terminal 5 as an example. The terminal body 501 of the first conductive terminal 5 is embedded in the first terminal fixing core; its contact portion 502 is located at the front end of the terminal body 501, specifically formed by the outward extension of the terminal body 501, increasing the thickness of the contact portion 502. The upper and lower contact surfaces in the thickness direction respectively constitute the upper electrical contact surface and the lower electrical contact surface, which can simultaneously contact the upper and lower contact points of the corresponding terminal of the TYPE-C dual-contact wire connector, realizing dual-contact electrical contact, thereby preventing screen flickering or momentary disconnection due to single-contact failure when the vehicle is subjected to road bumps and vibrations during driving, ensuring the connection stability between the vehicle data cable and the vehicle equipment; its welding portion 503 is located at the rear of the terminal body 501, used for welding to the PCB board to achieve mechanical fixation and electrical connection, ensuring effective transmission of power and signals.

[0034] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
