Fixed contacts, and the printed circuit board part is a flat design, assembled on the bottom of the insulated connector. By setting in this way, when the antenna is inserted into the antenna receiving cavity, the antenna part can hold the antenna relatively firmly by forming a certain angle with the insulating connector, and the printed circuit board part is slightly outward from the base of the connector. Extend, thereby maintaining the electrical connection between the metal contact and the printed circuit board. However, the disadvantage of this design is: the assembly process is difficult and complicated, and the welding configuration will make the assembly labor-intensive and increase the manufacturing cost, and because of the flat design of the printed circuit board part, it is easy to cause poor contact, short circuit, etc. Occurrence will directly affect the good rate of finished products.

【Content of utility model】

The purpose of the utility model is to provide an electrical connector which is easy to assemble, has good contact after assembly, and does not need welding.

The electric connector of the utility model is used to connect the printed circuit board and the antenna signal, and includes an insulating body and a metal sheet assembled on the insulating body, and the metal sheet includes an antenna contact portion, a printed circuit board contact portion and A base portion, and the base portion is respectively bent and extended to form the first and second elastic pieces, and the antenna contact portion and the printed circuit board contact portion are respectively arranged on the first and second elastic pieces.

Compared with the prior art, the utility model only enables the metal sheet to connect the printed circuit board and the antenna to transmit signals through elastic crimping between the printed circuit board contact portion of the metal sheet and the designated printed circuit board. Such arrangement does not require complex assembly procedures such as soldering, but only uses mechanical contact to achieve the purpose of signal transmission, reduces manufacturing costs, and enables the metal sheet to be accurately positioned on the printed circuit board.

【Detailed ways】

Please refer to FIG. 1 and FIG. 2 , the electrical connector 100 of the present invention includes an insulating body 1 and a metal sheet 2 assembled in the insulating body 1 for transmitting signals.

Please refer to FIG. 2 and FIG. 4 , the insulating body 1 is made of insulating material, and includes an upper surface 11 , a lower surface 12 and two sidewalls 13 for connecting the upper and lower surfaces 11 , 12 . The upper surface 11 and the lower surface 12 are respectively surrounded with the two side walls 13 to form first and second storage spaces 14, 15 for accommodating the metal sheet 2. In a tall stepped design, a matching portion 121 is provided at the front end of the lower surface 12 . In addition, two slots 131 are symmetrically provided at the position where the side wall 13 is adjacent to the upper surface 11 .

The metal sheet 2 is made of metal material for signal transmission, and is respectively accommodated in the first and second accommodation spaces 14 and 15 of the insulating body 1 through continuous bending. The metal sheet 2 is provided with a sheet-like base 20 , and the two ends of the base 20 are respectively bent and extended in obliquely upward and obliquely downward directions to form a first elastic piece 21 and a second elastic piece 22 . In addition, the base 20 of the metal sheet 2 is extended to both sides with a pair of protruding parts 23 for matching with the slots 131 on the side wall 13, and the base 20 is bent and extended obliquely downward to form a The buckling portion 24 is substantially in the shape of a "U". The ends of the first and second elastic pieces 21 , 22 respectively protrude to form an arc-shaped antenna contact portion 211 and a printed circuit board contact portion 221 .

Please refer to FIG. 1 to FIG. 4 , when assembling, the metal sheet 2 can be set on the insulating body 1 first. Position and insert the protruding parts 23 at both ends of the base 20 of the metal sheet 2 into the slots 131 on the side wall 13 of the insulating body 1, so that the base 20 is held on the insulating body 1, and at the same time, the base 20 of the metal sheet 2 The buckling portion 24 formed by bending and extending downward is docked with the mating portion 121 located at the front end of the lower surface 12 of the insulating housing 1 . At this time, the first elastic piece 21 of the metal sheet 2 will be accommodated in the first receiving space 14 of the insulating body 1, the first elastic piece 21 slightly protrudes outward from the first receiving space 14, and the second elastic piece 22 of the metal sheet 2 It will be accommodated in the second receiving space 15 of the insulating body 1 , and the second elastic piece 22 also slightly protrudes outward from the second receiving space 15 . The metal sheet 2 is designed with a special curved shape, which has better elasticity and greater elastic force, so that the antenna contact portion 211 on the first elastic piece 21 of the metal sheet 2 is more tightly bonded when mated with the antenna (not shown). better, and the printed circuit board contact portion 221 on the second elastic piece 22 of the metal sheet 2 will be press-fitted with the printed circuit board 4, that is, the metal sheet can be realized by using the elastic pressure of the printed circuit board contact portion 221. 2. The mechanical contact with the printed circuit board (not shown) completes the conductive connection between the antenna and the printed circuit board and the purpose of transmitting signals. In addition, the antenna can be plugged and held with the entire electrical connector 100 by directly cooperating with the casing or other receiving devices.
