Each metal housing 114 includes a ring body 114a and two soldering legs 114b extending outwardly from the bottom surface of the ring body 114a. The first strip 112 is also connected to the connecting strip 130 via a connection 118. The assembly units 110 and 112 are symmetrically arranged on opposite sides of the connecting strip 130, and the connecting strip 130 has a plurality of first positioning holes 132 therein. In this embodiment, the first workpiece 100 can be formed by stamping a metal plate body (not shown).

Referring to FIG. 2, a second workpiece 200 is provided. The second workpiece 200 has a second strip 210 having a plurality of second locating holes 204 therein. The opposite side edges of the strip 210 each have a plurality of center terminals 202, each center terminal being spaced apart from one another by a pitch. Each of the center terminals 202 includes a base portion 202b and a center post 202a disposed on the base portion 202b, and a second connecting portion 202c, and the second strip 210 and the center post 202a and the base portion 202b are respectively connected by the second connecting portion 202c. Connect to each other. In the present embodiment, the second workpiece 200 can be formed by stamping another metal plate body (not shown).

Referring to FIG. 3, the first positioning hole 132 on the first workpiece 100 and the second positioning hole 204 in the second workpiece 200 are overlapped and positioned with each other such that each center post 202a is correspondingly positioned in each ring body 114a. . It should be noted that the outer shape of the first workpiece 100 and the outer shape of the second workpiece 200 may be changed according to design requirements, as long as the first positioning holes 132 and the second on the first workpiece 100 are not affected. The second positioning holes 204 on the workpiece 200 are overlapped and positioned in contact with each other, and each of the center pillars 202a is correspondingly positioned in each of the ring bodies 114a. For example, the position of the metal housing 114 and the position of the center terminal 202 can be respectively exchanged, that is, each of the first assembly unit 110 and the second assembly unit 120 includes a first tape 112, a center terminal 202 and a first connection portion. 118, while the second workpiece 200 has a second tape 210 and a metal casing 114, but is not shown in the drawings.

Each of the ring bodies 114a is separated from the corresponding first connecting portions 118, and each of the central posts 202a and the corresponding respective bases 202b are separated from the second connecting portions 202c, thereby forming a plurality of independent RF connectors 500, as shown in FIG. Show. As can be seen from FIG. 5, the relative positions of the metal housing 114 of each of the independent RF connectors 500 and the center terminal 202 are maintained by the insulating body 402.

Please refer to FIG. 5, in which FIG. 5 shows an external view of a single RF connector of the present invention. The RF connector 500 of this embodiment includes a metal housing 114, a center terminal 202 and an insulative housing 402. The metal housing 114 includes a ring body 114a and two soldering legs 114b, and the two soldering legs 114b extend outwardly from the bottom surface of the ring body 114a. The center terminal 202 includes a base portion 202b and a center post 202a, and the center post 202a is disposed on the base portion 202b and extends through the ring body 114a. Insulating body 402 at least covers a portion of the ring body 114a and a portion of the base portion 202b to securely maintain the relative position of the metal housing 114 and the center terminal 202.

When the RF connector 500 is applied to a circuit board (not shown), the soldering legs 114b and the center terminal 202 of the metal housing 114 are soldered to corresponding electrical contacts of the circuit board. In addition, when another mating connector (not shown) is inserted into the RF connector 500, the function of transmitting the electrical signal can be achieved.

In summary, the method of manufacturing the RF connector of the present invention is characterized in that the second strip 210 of the second workpiece 200 can be cut into a plurality of pitches so as to overlap the first workpiece 100 for positioning. At the same time, the first workpiece 100 provides a symmetric bilateral metal housing 114 and the second workpiece 200 provides a symmetric bilateral center terminal 202, thus forming a symmetric bilateral RF connector finished product.
