Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a TYPE-C16PIN connector male connector. Background Technology

[0002] USB charging is the charging method for many electronic devices today, such as mobile phones and tablets. Most USB charging methods now involve a charging head connected to a circuit and a charging socket located inside the electronic device to charge it. A traditional Type-C connector male includes an insulator, terminals mounted within the insulator, and a metal shell covering the insulator. The front end of the metal shell and the insulator form a mating space for insertion with an external plug.

[0003] Patent CN219892470U discloses a 16P board connector male head. This solution solves the problem of the plastic body inside the male head detaching from the shell due to insertion and removal. However, this solution does not have a limiting structure for the terminal rebound. It only sets a through groove on the plastic body to avoid the terminal. The through groove cannot limit the rebound path of the terminal. After multiple insertions and removals, the position of the terminal will be uneven. When the plug is inserted again, the terminal is easy to bend and deform, which may damage the socket or cause a short circuit. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a TYPE-C16PIN connector male head. This invention limits the springback path of the terminals by setting a protective sleeve with a limiting groove, preventing the terminals of the connector male head from becoming uneven after repeated insertion and removal, and making the terminals less prone to bending and deformation, thereby avoiding damage to the socket or short circuit. It has the advantages of being stable, reliable and safe.

[0005] The technical solution adopted by this utility model is as follows: A TYPE-C16PIN connector male head includes a shell, a plastic component and several terminals are provided inside the shell, the several terminals are disposed on the plastic component, each terminal extends outward from the plastic component by a spring height, the shell is also provided with a protective sleeve, one end of the protective sleeve is provided with a socket, and the other end is provided with several limiting grooves for the spring heights to extend into, the several spring heights are disposed in the several limiting grooves, and a partition is provided between each two adjacent limiting grooves.

[0006] The plastic assembly includes two plastic parts, with a central clamp between the two plastic parts. Each of the two plastic parts has several terminals, and the inner walls of the upper and lower sides of the sheath are provided with limiting grooves.

[0007] The limiting groove has an abutment at one end edge near the insertion port, which abuts and limits the raised end within the limiting groove.

[0008] The sheath has clearance grooves on both sides for the middle clip to extend into, and the sheath also has two snap-fit ​​parts, with the two plastic parts snapping into the two snap-fit ​​parts respectively.

[0009] The inner edge of one end of the outer shell is provided with an inner arc portion. The end of the sheath away from the plastic part abuts against the inner arc portion. The edge of the plastic part away from the sheath has a protruding abutting block. The edge of the outer shell away from the inner arc portion abuts against the abutting block. Both sides of the middle clip have protruding protrusions. Both side walls of the outer shell are provided with assembly holes for the protrusions to engage.

[0010] Each of the two plastic parts is provided with a plug-in block and a plug-in slot. The plug-in block and the plug-in slot are adapted to each other. The middle clip is provided with a plug hole corresponding to the position of the plug-in block and the plug-in slot.

[0011] Both ends of the two plastic parts have raised baffles on their inner edges, and an embedded part for the middle clip to be inserted is formed between the two baffles.

[0012] The outer shell is made of metal or plastic, the middle clip and terminals are made of metal, and the plastic parts and sheaths are made of plastic.

[0013] The terminals are installed on the plastic parts by injection molding.

[0014] The beneficial effects of this utility model are as follows: This utility model limits the springback path of the terminal by setting a protective sleeve with a limiting groove. Each terminal has a separate limiting groove for its springback height, and adjacent limiting grooves are separated by a partition. This not only limits the springback direction of the terminal, but also limits the lateral movement space of the terminal, preventing the male connector from becoming uneven after multiple insertions and removals, and making the terminal less prone to bending and deformation. This avoids damage to the socket or short circuit, and has the advantages of being stable, reliable and safe. Attached Figure Description

Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0028] like Figures 1 to 8As shown, this is an embodiment of the present invention. A TYPE-C16PIN connector male includes a housing 1. The housing 1 contains a plastic component and several terminals 2. The terminals 2 are disposed on the plastic component. Each terminal 2 extends outward from the plastic component by a spring height 3. The housing 1 also contains a sheath 4. One end of the sheath 4 has a socket 5, and the other end has several limiting grooves 6 for the spring heights 3 to extend into. The spring heights 3 are disposed one by one in the several limiting grooves 6. A partition 7 is provided between each two adjacent limiting grooves 6.

[0029] The beneficial effects of this design are as follows: This utility model limits the springback path of the terminals by setting a protective sleeve with a limiting groove. Each terminal has a separate limiting groove for its springback height, and adjacent limiting grooves are separated by a partition. This not only limits the springback direction of the terminals but also limits the lateral movement space of the terminals, preventing the male connector from becoming uneven after multiple insertions and removals, and making the terminals less prone to bending and deformation. This avoids damaging the socket or causing a short circuit, and has the advantages of being stable, reliable, and safe.

[0030] Further configuration: the plastic component includes two plastic parts 8, a middle clamping piece 9 is provided between the two plastic parts 8, and a plurality of terminals 2 are provided on each of the two plastic parts 8. The upper and lower inner walls of the sheath 4 are provided with limiting grooves 6.

[0031] The beneficial effects of this design are as follows: the plastic component adopts a split assembly structure of two halves. In this embodiment, the two plastic parts have the same structure and are symmetrically arranged, which facilitates disassembly and assembly. In this embodiment, there are sixteen terminals, with eight terminals on each plastic part. The sheath is provided with limiting grooves corresponding to the positions of the two plastic parts, and the terminals on the two plastic parts can extend into the limiting grooves.

[0032] Furthermore, the limiting groove 6 is provided with an abutment part 21 at one end edge near the insertion port 5, and the abutment part 21 abuts and limits the end of the spring height 3 within the limiting groove 6.

[0033] The beneficial effects of this design are as follows: the abutting part abuts and limits the end of the terminal within the limiting groove, preventing the end of the terminal from being deformed by collision, further protecting the terminal, and also limiting the range of motion of the spring height.

[0034] Furthermore, the sheath 4 has clearance grooves 10 on both sides of its sidewalls for the insertion of the middle clamping piece 9, and the sheath 4 also has two snap-fit ​​parts 11, with the two plastic parts 8 respectively snap-fitting with the two snap-fit ​​parts 11.

[0035] The advantages of this design are as follows: the sheath and plastic parts adopt a snap-fit ​​assembly structure, the detachable connection structure makes it easy to replace sheaths or plastic parts of different sizes, and it can be assembled into male connectors of different sizes. The positioning groove is located in the middle of the two snap-fit ​​parts, which fits the position of the middle clip. The structure is compact and the installation is more secure.

[0036] Further configuration: an inner arc portion 12 is provided on the inner edge of one end of the outer shell 1; the end of the sheath 4 away from the plastic part 8 abuts against the inner arc portion 12; an abutment block 13 protrudes from the edge of the plastic part 8 away from the sheath 4; the edge of the outer shell 1 away from the inner arc portion 12 abuts against the abutment block 13; protrusions 14 protrude from both sides of the middle clip 9; and assembly holes 15 are provided on both side walls of the outer shell 1 for the protrusions 14 to engage.

[0037] The beneficial effects of this design are as follows: the sheath abuts against the inside of the outer shell through the inner arc, and the plastic part that is snapped into the sheath abuts against the outer shell through the abutment block. Both ends form abutment limits, and the sheath and the plastic part are firmly fixed inside the outer shell. The side of the outer shell also engages with the protrusion of the middle clip through the assembly hole to form a lateral fixing limit. Multiple limiting engagement points provide a more robust installation structure.

[0038] Furthermore, each of the two plastic parts 8 is provided with a plug block 16 and a plug groove 17, the plug block 16 and the plug groove 17 are adapted to each other, and the middle clamping piece 9 is provided with a plug hole 18 corresponding to the position of the plug block 16 and the plug groove 17 respectively.

[0039] The beneficial effects of this design are as follows: each plastic part has a plug-in block and a plug-in slot. The plug-in block on one plastic part mates with the plug-in slot on another plastic part. The two plastic parts are assembled together by the plug-in block and the plug-in slot. The plug-in block passes through the insertion hole of the middle clamping piece, and the middle clamping piece is firmly clamped between the two plastic parts, making it difficult for the two plastic parts to loosen or rotate out of place.

[0040] Furthermore, both ends of the two plastic parts 8 have raised baffles 19 on their inner edges, and an embedded portion 20 for the middle clip 9 to be inserted is formed between the two baffles 19.

[0041] The beneficial effects of this design are as follows: the embedded part formed by the two baffles holds the middle clip in place, which restricts the middle clip in both the horizontal and vertical directions, preventing the middle clip from sliding between the two plastic parts. The baffles on the two plastic parts also abut against each other, fit tightly together, and reduce gaps.

[0042] Further configuration: the outer shell 1 is made of metal or plastic, the middle clip 9 and the terminal 2 are both made of metal, and the plastic parts 8 and the sheath 4 are both made of plastic.

[0043] The advantages of this design are as follows: the outer shell can be made of metal or plastic, making it highly replaceable.

[0044] Furthermore, the terminal 2 is installed on the plastic part 8 by injection molding.

[0045] The advantages of this setup are as follows: the terminals can be installed on the plastic parts by injection molding, or the plastic parts can be injection molded separately first, and then the terminals can be assembled on the plastic parts. The sheath and the plastic parts can also be injection molded as a whole, or they can be injection molded separately and then assembled.

[0046] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
