Referring to fig. 1 to 13, in an embodiment of the present application, the board Type-C connector includes a housing 100, an insulating body 200, a locking body 300, and a terminal assembly 400. The insulating body 200 is disposed in the housing 100, and the insulating body 200 has a plurality of first accommodating grooves 210; the locking body 300 is connected with the insulating body 200, and the locking body 300 has a plurality of second receiving grooves 310; the terminal assembly 400 includes a PCB assembly 410 and a plurality of metal terminals 420, the PCB assembly 410 is disposed on the insulating body 200 and between the insulating body 200 and the locking body 300, the PCB assembly 410 is configured to fix the plurality of metal terminals 420, one ends of the plurality of metal terminals 420 are disposed in the plurality of first accommodating grooves 210, and the other ends are disposed in the plurality of second accommodating grooves 310; the locking body 300 is provided with a socket 320 at a side away from the insulating body 200, and the socket 320 is used for inserting the circuit board 700.
Specifically, referring to fig. 8 and 10 to 13, the housing 100 is made of metal material, the insulating body 200 is disposed in the housing 100, and the housing 100 is mainly used for covering the insulating body 200 and the plurality of metal terminals 420, so as to provide a metal shielding effect, and protect other components in the housing 100. The insulating main body 200 is made of plastic insulating materials, a plurality of first accommodating grooves 210 used for accommodating the metal terminals 420 are formed in the insulating main body 200, the first accommodating grooves 210 are respectively formed in the upper side and the lower side of the insulating main body 200, and the first accommodating grooves 210 are separated from each other and are not communicated with each other, so that the metal terminals 420 are prevented from being conducted in the using process, and meanwhile, the first accommodating grooves 210 also play a certain limiting role on the metal terminals 420, and the metal terminals 420 are prevented from being misplaced when being used for plugging for a long time.
Referring to fig. 3 to 7, the locking body 300 is also made of plastic insulation material, thereby performing an insulation function. The locking body 300 and the insulating body 200 may be connected together by a snap-fit connection or by other connection means such as adhesion, and in this embodiment, the locking body 300 and the insulating body 200 are connected by a snap-fit connection for ease of assembly. The locking main body 300 is provided with a plurality of second accommodating grooves 310 for accommodating the other ends of the metal terminals 420, the second accommodating grooves 310 are respectively positioned on the upper side and the lower side of the locking main body 300, and the second accommodating grooves 310 are mutually separated and not communicated, so that the plurality of metal terminals 420 are prevented from being conducted in the using process, and meanwhile, the plurality of second accommodating grooves 310 also play a certain limiting role on the plurality of metal terminals 420, so that the metal terminals 420 are prevented from being misplaced when being used for a long time for plugging. The first accommodating groove 210 and the second accommodating groove 310 are generally square open through grooves.
Further, compared with the conventional metal terminal 420 connected to the insulating body 200 and the locking body 300 by encapsulation, the two ends of the metal terminal 420 in the plug-in Type-C connector of the present application are respectively disposed in the first accommodating groove 210 of the insulating body 200 and the second accommodating groove 310 of the locking body 300, so that the area of the metal terminal 420 in direct contact with the plastic material is smaller, and thus the dielectric constant requirement of the plastic material is not strict, i.e. the material requirements of the insulating body 200 and the locking body 300 are not strict. The conventional metal terminal 420 is connected with the insulating body 200 and the locking body 300 in an encapsulation manner, so that the requirements on materials of the insulating body 200 and the locking body 300 are high, and the requirements on the production process and the like of the insulating body 200 and the locking body 300 are more strict.
Referring to fig. 9, the terminal assembly 400 is disposed in the insulating body 200 and is located in the housing 100, the terminal assembly 400 includes a PCB assembly 410 and a plurality of metal terminals 420, the plurality of metal terminals 420 are fixed by the PCB assembly 410, two ends of the fixed plurality of metal terminals 420 are respectively inserted into the first accommodating groove 210 of the insulating body 200 and the second accommodating groove 310 of the locking body 300, and the PCB assembly 410 is located between the insulating body 200 and the locking body 300. In view of the requirement of elasticity and rigidity, the metal terminal 420 is made of alloy copper, which may be brass, phosphor bronze, or other kinds of alloy copper, and is not particularly limited. The number of the metal terminals 420 is set to be plural, and the number of the metal terminals 420 can be selected independently according to actual needs, specifically in this embodiment, the number of the metal terminals 420 is set to be 24, and the 24 metal terminals 420 are respectively located in the first accommodating groove 210 and the second accommodating groove 310 on the upper side and the lower side of the Type-C connector. The number of the first receiving grooves 210 and the second receiving grooves 310 is also plural, and the number of the first receiving grooves 210 and the second receiving grooves 310 is only required to be ensured to be not less than the number of the metal terminals 420, which is not particularly limited.
Referring to fig. 2 to 7, the locking body 300 has a socket 320 at a side away from the insulating body 200, and the socket 320 can be inserted by an external circuit board 700 to electrically connect the circuit board 700 with the metal terminals 420. The conventional circuit board 700 is electrically connected to the Type-C connector by soldering, so that multimedia signals are transmitted through the circuit board 700, and output current provided by the circuit board 700 is received. However, because the pin pitch in the Type-C connector is small, when the pins are soldered to the circuit board 700, there is a high requirement on the solder joints between the pins and the circuit board 700, for example, the solder joints are required to be as smooth as possible, particularly tin sharp burrs and the like are not allowed, the requirement on soldering is high, the operation is time-consuming and labor-consuming, and the cost is high. According to the application, the plugging port 320 for the external circuit board 700 to be plugged in is arranged on one side of the locking main body 300 far away from the insulating main body 200, and the circuit board 700 is plugged into the plugging port 320, so that the electric connection between the Type-C connector and the external circuit board 700 can be realized, the operation is convenient, simple, quick and stable, the trouble and risk of welding the traditional Type-C connector and the circuit board 700 are avoided, and the circuit board 700 can be repeatedly plugged and unplugged for use. Meanwhile, the plug board Type-C connector is higher in consistency, high in yield of production and processing, simple in relative test link, relatively low in requirement on test equipment and capable of further reducing production cost. The height of the plug 320 is adapted to the thickness of the circuit board 700, and the requirement of the circuit board 700 with different thickness can be met by replacing the locking main body 300 with a different locking main body 300, i.e. replacing the locking main body 300 with a different height of the plug 320.
The board Type-C connector of the present application includes a housing 100, an insulating body 200, a locking body 300, and a terminal assembly 400.
