Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to the TYPE-C-16P SMT waterproof female connector. Background Technology

[0002] Type-C connectors are blind-mating electrical signal transmission interfaces. The connection structure of this type of interface does not require distinguishing between the front and back, and can be plugged in from both sides. In this way, Type-C connectors can transmit electrical signals or charge between external devices and internal devices (such as mobile phones, computers, etc.) through the Type-C interface.

[0003] For example, Chinese patent document CN215184734U discloses a TYPE-C DIP front-plug SMT rear-attach 24-pin waterproof female connector, including a metal shell, a tongue plate, terminals, and pins. The metal shell is a hollow cavity structure with an open front. The tongue plate is located inside the metal shell, the pins are symmetrically arranged above and below the tongue plate, and the terminals are located below the metal shell, passing through the tongue plate and connecting to the pins. This belongs to the field of charging equipment technology, specifically referring to a TYPE-C DIP front-plug SMT rear-attach 24-pin waterproof female connector with a waterproof ring to enhance water repellency and prevent short circuits.

[0004] For example, Chinese patent document CN222673400U discloses an SMT female terminal connector, including a housing, an inner housing installed inside the housing, a plastic body disposed inside the inner housing, an upper row of terminals disposed on the inner housing, retaining feet disposed on the extension ends of the upper row of terminals, and a lower row of terminals disposed on the retaining feet. A front shielding sheet is laser-spotted and bent 90 degrees on the housing, and the inner housing is installed inside the housing, with the plastic body mounted on the inner housing. Two sets of mounting holes are symmetrically arranged at the top ends of the plastic body. The upper row of terminals is mounted on the plastic body, and the upper row of terminals are integrated with the lower row of terminals. The internal center height is higher than 4mm, thus facilitating the connection of more devices. Alternatively, Chinese patent document CN206524476U discloses a single-row SMT-type USB Type-C female connector, which includes a metal shell and a terminal core body installed inside the metal shell. The terminal core body is divided into an upper terminal core, a lower terminal core, and a separator core, with the separator core located between the upper and lower terminal cores. The front sections of the upper row of terminals in the upper terminal core and the lower row of terminals in the lower terminal core are located on the upper and lower surfaces of the separator core, respectively, and on the left and right sides. The tails of the upper and lower rows of terminals are at the same height and are arranged flush. The upper and lower terminals are arranged left and right in a centrally symmetrical manner, reducing unnecessary waste and allowing for reversible insertion. The flush design of the tails of the upper and lower rows of terminals allows for SMT (Surface Mount Technology) processes.

[0005] However, for the plastic body (core) of the fixed terminal, the existing technology is to directly injection mold it on the outside of the arranged terminals in one step. Since the shape of the plastic body has strict requirements to fit the male socket, the arrangement, positioning and injection process of the terminals have high requirements. It takes a long time to occupy the same station, which also increases the manufacturing cost to a certain extent. Summary of the Invention

[0006] In view of the above-mentioned technical problems, the present invention provides a TYPE-C-16P SMT waterproof female connector.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0009] The inner core assembly is located in the receiving hole and includes multiple terminals arranged in a row, positioning blocks and shaping blocks. The positioning blocks are injection molded onto the arranged terminals to form a pre-formed module. The shaping blocks are injection molded to wrap around the pre-formed module to form a preset shape on the outer surface of the inner core assembly.

[0010] The rear end of the plastic block is fixed to the plastic shell as a fixing part. The rear end of the receiving hole is filled with sealant and pressed against the plastic block. The front end of the plastic block is a tongue plate that maintains a gap with the side wall of the receiving hole. Each terminal is partially exposed from the top and bottom of the tongue plate.

The sides of the plastic shell are provided with buckles, and the metal frame is provided with buckle holes that cooperate with the buckles, so that the metal frame can be detachably fixed. The two ends of the metal frame are provided with connecting parts, which can be insert plate structure, plate structure or screw hole structure.

[0012] The outer side of the plastic shell has an annular groove near the front port, and a sealing ring is installed in the groove.

[0013] Specifically, the top and sides of the plastic shell are recessed to form relief grooves, and the metal frame is fitted into the relief grooves.

[0014] Specifically, the inner core component also includes metal hooks that extend from both sides of the molded block.

[0015] Specifically, the inner wall of the receiving hole is provided with an annular limiting protrusion, and the shaping block includes a stop section, an interpenetrating section, a transition section and a tongue section with progressively decreasing thickness from back to front. The stop section abuts against the rear end face of the limiting protrusion, the interpenetrating section abuts against the inner wall surface of the limiting protrusion, and the transition section and the tongue section are cantilevered.

[0016] Specifically, the sidewalls of the receiving hole are provided with guide ribs.

[0017] Specifically, the bottom of the plastic shell is integrally molded with two separate uprights.

[0018] Specifically, the tongue plate extends to the front port of the receiving hole.

[0019] Specifically, the tongue plate retracts into the receiving hole.

[0020] Specifically, the insert structure is a two-legged insert or a four-legged insert.

[0021] Specifically, the mounting plate structure is a two-legged mounting plate or a four-legged mounting plate.

[0022] The beneficial effects of this utility model are:

[0023] Compared with existing technologies, the TYPE-C-16P SMT waterproof female connector of this utility model has a sealing ring on the outer side of the plastic shell and is filled with sealant at the rear end, thus providing better sealing and waterproof performance. Furthermore, the structure of the inner core component fixing terminals is divided into positioning blocks and molding blocks. During production, positioning blocks are first injection molded on the outside of the positioned terminals, thus arranging and positioning multiple terminals to form a pre-formed module. Then, molding blocks are injection molded to obtain the preset shape. This two-stage injection molding facilitates modular manufacturing and allows for step-by-step accelerated manufacturing on the production line, thereby improving production efficiency.

[0044] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] The TYPE-C-16P SMT waterproof female connector in this embodiment, such as Figures 1 to 4 As shown, it includes a plastic shell 1, a metal frame 2, and an inner core assembly 3. The plastic shell 1 has a through-hole elliptical receiving hole 11, and the plastic shell 1 is a one-piece cast structure. In the name, 16P indicates 16 terminals 31. SMT has a fixed and mature meaning in the existing technology, and will not be elaborated here.

[0046] The inner core assembly 3 is located in the receiving hole 11 and includes multiple terminals 31 arranged in a row, positioning blocks 32, and shaping blocks 33. The positioning blocks 32 are injection molded onto the arranged terminals 31 to form a pre-formed module. During production, the positioning blocks 32 are first injection molded onto the outside of the positioned terminals 31, thus using less plastic to arrange and position the multiple terminals 31. Then, the shaping blocks 33 are injection molded onto the outside of the pre-formed module, that is, the shaping blocks 33 are injection molded to wrap around the pre-formed module to form the preset shape of the outer surface of the inner core assembly 3 and obtain the required shape. Compared with the prior art, the pre-positioning and outer surface shaping of the terminals 31 are completed in steps, reducing manufacturing difficulty and improving production efficiency.

[0047] The rear end of the molding block 33 is fixed to the plastic shell 1 as a fixing part. The rear end of the receiving hole 11 is filled with sealant 4 and pressed against the molding block. The front end of the molding block 33 serves as a tongue plate to maintain a gap with the side wall of the receiving hole 11. Each terminal 31 is partially exposed from the top and bottom of the tongue plate. The rear end of each terminal 31 extends out of the plastic shell 1 and is neatly arranged.

[0048] The metal frame 2 is U-shaped and fits against the top and sides of the plastic shell 1. The sides of the plastic shell 1 are provided with buckles 12, and the metal frame 2 has locking holes 21 that mate with the buckles 12, allowing the metal frame 2 to be detachably fixed to the plastic shell 1. Both ends of the metal frame 2 are provided with connecting parts 22 for fixing to an external circuit board. The connecting parts 22 can be a plug-in structure, a mounting structure, or a screw hole structure. Figure 6 and Figure 11 The shown insert structure is a four-pronged insert, with two inserts on each side, which are inserted into the openings on the circuit board for fixation or fixed by a combination of insertion and spot welding.

Figure 7 and Figure 12 The panel structure shown is a double-sided panel, with one panel on each side. Figure 1 and Figure 9 The screw hole structure shown is used to fix the metal frame 2 to the circuit board with screws.

[0049] In this embodiment, an annular groove 13 is provided on the outer side of the plastic shell 1 near the front port. A sealing ring 5 is provided in the groove 13 to cooperate with the opening of the product and play a sealing role.

[0050] Specifically, the top and sides of the plastic shell 1 are recessed to form relief grooves 14, and the metal frame 2 is fitted into the relief grooves 14, making the structure more compact.

[0051] Specifically, the inner core component 3 also includes metal hooks 35, which extend from both sides of the molded block. During production, multiple terminals 31 and hooks 35 are pre-fixed, and then the positioning block 32 is injection molded.

[0052] Specifically, the inner wall of the receiving hole 11 is provided with an annular limiting protrusion 15. The molding block includes a stop section 331, an interpenetrating section 332, a transition section 333, and a tongue section 334, with the thickness decreasing sequentially from back to front. The stop section 331 abuts against the rear end face of the limiting protrusion 15, the interpenetrating section 332 abuts against the inner wall face of the limiting protrusion 15, and the transition section 333 and the tongue section 334 are cantilevered. During installation, the rear end of the inner core assembly 3 is directly inserted into the receiving hole 11 until the stop section 331 abuts against the limiting protrusion 15, thus completing the installation in one step.

[0053] Specifically, the side wall of the receiving hole 11 has guide ribs 16 to facilitate the insertion of the male seat.

[0054] Specifically, the bottom of the plastic shell 1 is integrally formed with two separate columns 17.

[0055] Specifically, such as Figure 1 as well as Figures 5 to 8 The tongue plate (tongue segment 334) shown retracts into the receiving hole 11. Or as Figures 9 to 13 The tongue plate shown extends to the front port of the receiving hole 11.
