Description

Technical Field

[0001] This utility model relates to the field of USB TYPE-C connector technology, specifically a short-body single-row SMT recessed USB TYPE-C connector. Background Technology

[0002] Currently, USB Type-C connectors on the market generally suffer from issues such as excessive overall length and exposed shells that affect aesthetics. In terms of structural design, the assembly of various components in some connectors is not secure enough, which can easily damage the internal structure when the plug is inserted. Furthermore, the current withstand capability needs improvement. Additionally, the solder pin design is not ideal for soldering to the PCB board, making it difficult to perform the soldering operation and meet the requirements of relevant standards such as USB TID and IEC. Utility Model Content

[0003] The purpose of this invention is to provide a short-body, single-row SMT recessed USB TYPE-C connector to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a short-body single-row SMT recessed USBTYPE-C connector, comprising a housing and a plastic terminal housing, wherein a plastic terminal housing is snapped into the inside of the housing, a plastic mounting component is snapped into the inside of the plastic terminal housing, an upper terminal is snapped into the top of the plastic mounting component, a plastic sleeve is fitted onto the upper terminal, a middle clip is snapped into the middle of the plastic mounting component, and a lower terminal is snapped into the bottom of the plastic mounting component.

[0005] Compared to the common USB Type-C connectors on the market, this product has a smaller overall length, and the outer shell is not exposed, making the product more aesthetically pleasing. During assembly, first, the plastic sleeve is put onto the upper terminal, then the lower terminal and the middle clip are snapped into the plastic mounting piece, then the upper terminal is snapped into the plastic mounting piece, then the plastic mounting piece is snapped into the plastic terminal housing, and finally the plastic terminal housing is inserted into the housing. At this time, the clips on the housing engage with the slots on the plastic terminal housing.

[0006] Preferably, the top surface of the housing is provided with two symmetrical contact springs, one side of the top surface of the housing is provided with two cards, and one side of the top of the plastic terminal housing is provided with two card slots, and the two cards are respectively engaged with the two card slots.

[0007] Preferably, the plastic terminal housing has two limiting grooves on its top and bottom surfaces, and two symmetrical recesses on its top and bottom surfaces. These recesses correspond to the limiting grooves and engage with them. The recesses limit the plastic terminal housing's position and also stop the insertion depth of the plug, preventing the plug from directly pressing against the plastic terminal housing and damaging the product.

[0008] Preferably, the two sides of the middle clip are in contact with the inner wall of the outer shell, and the middle clip and the outer shell have a contact and conductive structure, which can improve the current resistance of the product.

[0009] Preferably, the plastic terminal housing has two symmetrical contact bumps on the ground. The design of the housing contact spring and the contact bumps can make the plug contact the housing more tightly after insertion, thereby improving the product's current resistance; it also meets the requirements of USB TID and IEC.

[0010] Preferably, each of the four corners at the bottom of the housing is provided with solder feet, and the solder feet are all chamfered. The chamfering of the solder feet is more conducive to guiding the product into the PCB and realizing through-hole reflow soldering.

[0011] Preferably, the ends of the upper and lower terminals are both "duckbill" shaped, and the contact heads of the upper and lower terminals are "duckbill" structures. They are embedded in the plastic terminal housing and have excellent bonding strength, which can prevent the force generated when the plug is inserted from flipping the upper and lower terminals over and exposing them.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This short-body, single-row SMT recessed USB Type-C connector has a smaller overall length and an unexposed housing, improving the product's aesthetics. A well-designed snap-fit ​​structure ensures stable assembly of all components. The combination of recessed and limiting grooves effectively prevents damage to the product during plug insertion. The contact conductivity between the middle clip and the housing, along with the design of the contact spring and contact bump, enhances the product's current withstand capability and meets relevant standards. The chamfered solder feet facilitate soldering to the PCB board. The "duckbill" shaped terminal ends prevent the terminals from flipping over and becoming exposed, thus improving overall product performance and reliability. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-8 This utility model provides a short-body single-row SMT recessed USB TYPE-C connector, including a housing 1 and a plastic terminal housing 2. The plastic terminal housing 2 is snapped into the inside of the housing 1. The plastic mounting part 5 is snapped into the inside of the plastic terminal housing 2. The top of the plastic mounting part 5 is snapped into an upper terminal 3. A plastic sleeve 4 is fitted on the upper terminal 3. A middle clip 7 is snapped into the middle of the plastic mounting part 5. The bottom of the plastic mounting part 7 is snapped into a lower terminal 6.

[0025] The top surface of the outer casing 1 is provided with two symmetrical contact springs 8, and one side of the top surface of the outer casing 1 is provided with two cards 10. The top side of the plastic terminal outer casing 2 is provided with two card slots 12, and the two cards 10 are respectively engaged with the two card slots 10.

[0026] Specifically, the contact spring 8 is used to hold the plug in place, making the plug inserted more tightly; by inserting the card 10 into the card slot 10, the assembly between the housing 1 and the plastic terminal housing 2 can be achieved.

[0027] The plastic terminal housing 2 has two limiting grooves 13 on its top and bottom. The top surface and the ground surface of the housing 1 are symmetrically provided with two recesses 9. The recesses 9 are corresponding to the limiting grooves 13 and are inserted into the limiting grooves 13.

[0028] Specifically, the recessed groove 9 is inserted into the limiting groove 13. On the one hand, it limits the position of the plastic terminal housing 2 within the housing 1, ensuring assembly accuracy. On the other hand, when the plug is inserted, the recessed groove 9 can stop the insertion depth of the plug, preventing the plug from directly pressing against the plastic terminal housing 2 and causing product damage.

[0029] The two sides of the middle clip 7 are in contact with the inner wall of the outer shell 1 and are connected.

[0030] Specifically, the middle clip 7 makes contact with the outer casing 1, increasing the current conduction path and thus improving the product's current resistance, making the product more stable and reliable when operating at high current.

[0031] The plastic terminal housing 2 has two symmetrical contact protrusions 11 on its ground.

[0032] Specifically, when the plug is inserted, the contact spring 8 on the outer shell 1 cooperates with the contact protrusion 11 on the plastic terminal outer shell 2, making the plug and the outer shell 1 more tightly connected, further improving the current resistance of the product. At the same time, this design also meets the relevant standard requirements of USBTID and IEC.

[0033] The bottom of the outer casing 1 has four corners with solder feet 14, and the solder feet 14 are all chamfered.

[0034] Specifically, solder feet 14 are used to solder the connector to the PCB board. The chamfering of solder feet 14 makes it easier to insert into the PCB board, which is convenient and facilitates through-hole reflow soldering, ensuring the quality and stability of the soldering.

[0035] Both the upper terminal 3 and the lower terminal 6 have "duckbill" shaped ends.

[0036] Specifically, the "duckbill" shaped structure makes the connection between the upper terminal 3 and the lower terminal 6 stronger when embedded in the plastic terminal housing 2. When the plug is inserted, it can effectively resist the insertion force and prevent the upper terminal 3 and the lower terminal 6 from being pushed over and exposed, thus ensuring the normal operation and service life of the connector.

[0037] Working principle: During assembly, first, the plastic sleeve 4 is fitted onto the upper terminal 3, then the lower terminal 6 and the middle clip 7 are inserted into the plastic mounting piece 5. Next, the upper terminal 3 is inserted into the plastic mounting piece 5, then the plastic mounting piece 5 is inserted into the plastic terminal housing 2. Finally, the plastic terminal housing 2 is inserted into the housing 1. At this time, the clip 10 on the housing 1 engages with the slot 12 on the plastic terminal housing 2, completing the assembly. During use, the plug is inserted into the connector. The contact spring 8 and the contact protrusion 11 cooperate to ensure tight contact. The concave 9 and the limiting groove 13 cooperate to limit the insertion depth. The middle clip 7 conducts electricity with the housing 1 to improve current withstand capability. The solder foot 14 achieves stable soldering to the PCB board. The "duckbill" shaped terminal end prevents the terminal from flipping over, ensuring stable operation of the connector.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
