Description

Technical Field

[0001] This utility model relates to the field of Type-C connector technology, and in particular to a Type-C connector with a sheath. Background Technology

[0002] Type-C connectors are widely used in advanced infotainment, camera equipment, telematics, rear-seat entertainment systems, and charging systems. To protect the device during insertion and removal, the female connector of a Type-C connector may have a protective shell or sleeve. The structure / form of the protective shell or sleeve varies depending on the structure of the female connector.

[0003] For example, patent number 201821946922.1 describes a recessed female connector, a recessed USB connector, and a mobile terminal. The female connector includes a PCB board, a female connector body, and a protective sleeve. The female connector body is mounted on top of the PCB board, and the protective sleeve covers the female connector body and is soldered to the PCB board. Corresponding positioning structures are provided on the female connector body and the protective sleeve. This structure is not a fully enclosed structure; if improved shielding performance is required, it needs to be coated with adhesive or an additional shielding shell needs to be added. Furthermore, the positioning and soldering of the protective sleeve during assembly is relatively complicated.

[0004] For example, patent number 202210329177.0 describes a connector comprising a PCB board, a housing, and a female connector. The female connector is composed of an inner shell and an insulating base, among other components. The housing has corresponding spring clips and limiting structures to achieve mating and fixation with the female connector. The female connector is mounted on the upper side of the PCB board, and the housing covers the female connector, enclosing the portion excluding the plug port. This structure is a fully enclosed structure, providing good shielding and protection. However, its structure is relatively complex, requiring numerous sheet metal components with high requirements, resulting in relatively high production costs.

[0005] For example, patent number 202221656743.0 describes an automotive-grade TYPE-C connector, which includes a connector body, a plastic protective shell, and a metal shielded welded shell. The plastic protective shell and the metal shielded welded shell are connected by a mating structure, with the mating direction being the same as the insertion and removal direction of the connector body. The connector body is enclosed within the internal space formed by these components, with the metal shielded welded shell located at the rear end of the connector body. Its disadvantages are: the mating direction of the plastic protective shell and the metal shielded welded shell is the same as the insertion and removal direction of the connector body. During long-term use, the connection between the plastic protective shell and the metal shielded welded shell is prone to loosening, and users may easily forget to release the locking mechanism of the plastic protective shell, further exacerbating the loosening problem. Furthermore, the mating structure between the plastic protective shell and the metal shielded welded shell is relatively complex, requiring numerous positioning and limiting structures to ensure mating strength, resulting in higher production costs, especially as misalignment is prone to occur during assembly.

[0006] Therefore, there is an urgent need for a sheathed Type-C connector that can solve one or more of the above problems. Utility Model Content

The connector body is inserted into the installation channel, and the head end of the connector body is limited by the head end of the installation channel.

[0009] A fixing shell is provided to fix the protective sleeve and the connector body on the PCB board. The fixing shell is provided with an upper plate, which is installed at the mounting position. The projection of the upper plate on the PCB board covers the projection of the tail end of the connector body on the PCB board. The upper plate is provided with a fixing foot extending towards the PCB board. The fixing foot passes through the insertion hole and enters the first mating hole.

Detailed Implementation

[0027] To make the above-mentioned objectives, features, and advantages of this utility model more readily understood, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0028] This utility model discloses a Type-C connector with a protective sleeve, combined with Figure 1 , Figure 2 As shown, it includes: connector body 1, protective sleeve 2 and fixing shell 3. The connector body 1 is mounted on the upper side of PCB board 4. PCB board 4 is provided with a first mating hole 40.

[0029] Combination Figure 3 , Figure 5 , Figure 6 As shown, the protective sleeve 2 forms an installation channel 20, and an installation position 22 is provided on the upper side of the installation channel 20. The installation position 22 is provided with a socket 220 facing the PCB board 4. The socket 220 is located on both sides of the installation channel 20 in the non-opening direction. The connector body 1 is inserted into the installation channel 20, and the head end of the connector body 1 is limited by the head end of the installation channel 20.

[0030] Combination Figure 2 , Figures 4-6 As shown, the fixing shell 3 fixes the protective sleeve 2 and the connector body 1 to the PCB board 4. The fixing shell 3 is provided with an upper plate 30, which is installed at the mounting position 22. The projection of the upper plate 30 on the PCB board 4 covers the projection of the tail end of the connector body 1 on the PCB board 4. The upper plate 30 is provided with a fixing foot 31 extending toward the PCB board 4. The fixing foot 31 passes through the insertion hole 220 and enters the first mating hole 40. The fixing shell 3 is provided with a limiting plate 32 extending toward the PCB board 4. The tail end of the connector body 1 is limited by the limiting plate 32.

[0031] Specifically, in combination Figure 2As shown, the connector body 1 is provided with pins 10 extending toward the PCB board 4, and the PCB board 4 is provided with a second mating hole 42, into which the pins 10 are inserted. Furthermore, the PCB board 4 is provided with pads 41 corresponding to the pins of the connector body 1. The protective sleeve 2 may be provided with a limiting step to limit the installation height of the connector body 1 on the PCB board 4, so as to prevent the connector body 1 from being compressed during assembly or use, causing the pins to collide with the pads 41 and thus bend the pins.

[0032] It should be noted that the protective sleeve 2 is an integral plastic shell, and the fixing shell 3 is a metal shell. By wrapping the tail end of the connector body 1 with the fixing shell 3, the shielding performance is enhanced and the center of gravity of the product is forced to shift to the position of the solder pad 41.

[0033] Specifically, in combination Figure 3 , Figure 4 and Figure 6 As shown, the protective sleeve 2 forms a mating channel 21, which is located at the head end of the mounting channel 20 and communicates with it. A latch 210 is provided on one side of the mating channel 21. Furthermore, the mating channel 21 guides the male connector to mate with the female connector of the connector body 1 and increases the sealing of the connection end, thereby enhancing shielding performance, waterproof and dustproof performance, and locking between the latches of the male and female connectors.

[0034] like Figure 3 As shown, the interval between two adjacent insertion holes 220 is a limiting post 221, and a slot 33 is formed between two adjacent fixing feet 31. The slot 33 engages with the limiting post 221 to strengthen the connection between the fixing shell 3 and the wrapping sleeve 2, and to limit the insertion depth of the fixing shell 3, thereby improving the strength and stability of the product.

[0035] Combination Figure 6 As shown, the limiting plate 221 includes a starting section and a tail section. The tail section overlaps with the tail end of the connector body 1. The starting section is connected to the upper plate 30. The starting section and the tail end are connected by a transition section. The transition section extends toward the tail end of the connector body 1. The transition section is an arc transition and / or a ramp transition, which ultimately makes the limiting plate 32 form an elastic overlapping stop structure. This improves the ease of assembly and fault tolerance while locking the connector body 1, and avoids damage to the tail end of the connector body 1 during the locking and fixing process.

[0036] like Figure 2As shown, a protrusion 310 is provided on the side wall of the fixing foot 31. The protrusion 310 is interference-fitted with the insertion hole 220, the purpose of which is to improve the connection strength between the fixing shell 3 and the protective sleeve 2. Figure 2 , Figure 3 As shown, the mounting position 22 is a groove, and the upper plate 30 is limited by the mounting position 22. The mounting position 22 is formed with an inclined surface and / or an arc surface for guiding the insertion of the fixing foot 31. Figure 2 , Figure 5 , Figure 6 As shown, the protective sleeve 2 has a step 23, which is engaged with the PCB board 4 and can play a preliminary positioning role during assembly.

[0037] During assembly, the pins 10 of the connector body 1 are soldered to the PCB board 4, and the fixing feet 31 of the fixing shell 3 are soldered to the PCB board 4.

[0038] In summary, the aforementioned fixing shell secures the protective sleeve and connector body to the PCB board, providing full protection for the connector body while improving the shielding performance for Type-C signals. Structurally, it is simpler than the traditional recessed design, with lower assembly process and cost, and is also more resistant to insertion and removal. It is also compatible with traditional locking structures. The integrated protective sleeve and metal fixing shell can shift the product's center of gravity to the solder pad position to meet the needs of subsequent production and use.
