New description: [New technical field] This creation is related to the electrical connector, which is an electrical connector with two-layer staggered terminals. [Prior Art] As shown in Figure 1, due to advances in technology, the capacity of data-disconnected devices is increasing. In order for the transmission equipment to load more data transmission traffic, the electrical connector must be connected to the terminal. The number 'such as the USB3.G electrical connector is connected to the terminal group 10 of the phase-level USB1Q/2 ,, and a second set of second terminal groups 2 增加 is added to increase the data transmission stream! The first terminal group 1〇 and the second terminal group 20 need to be staggered, and each terminal must be isolated from each other to maintain mutual insulation from each other. In order to fix the staggered first terminal group 10 and the second terminal group 2 in a narrow space, the first terminal group 10 and the second terminal group 2 are respectively embedded in the insulated terminal block 30 and the first terminal, respectively. After the socket 40, the first terminal block 30 and the second terminal block 4 are joined through the positioning base 5, so that the first terminal group 1〇 and the second terminal group 2 are staggered and insulated from each other. Finally, the aforementioned components are incorporated into a shielded housing 60 to complete an electrical connector conforming to the USB 3.0 protocol. Although the electrical connector shown in Fig. 1 effectively arranges and isolates the terminals in a small space, the manufacturing process of such a structure is complicated, and the construction of such a large number of components in a small space is equivalent in manufacturing and assembly. Difficulty, so the processing cost of this structure is very high. [New content] In view of this, Feng Creative proposed an electrical connector comprising a plurality of first terminals, a plurality of 3 M381196 second terminals, a terminal block and an embedding block. Each of the first terminals includes a first contact end and a - - solder joint. The tree 帛 - 轩 地 般 概 概 概 概 概 概 概 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩 轩Each of the second terminals includes a first contact end and a - first solder end. The embedding block is formed on the terminal block, and each of the second terminals is not embedded in the red block, so that each of the second contact ends and each of the second soldering ends are exposed outside the embedding block . The f-connector of the present invention is covered with a surface-shaped surface, and the sockets and the embedded blocks are formed so that the terminal covers are fixed to the towel, and are not manually assembled, and can effectively make the first - There are no second welded ends on the welded end that are not fine with each other, achieving a good margin effect. [Embodiment] FIG. 2-5 is an electrical connector disclosed in the present embodiment, wherein FIG. 2 is a schematic view of the terminal block 300 and the first terminal 100, and FIG. 3 is a second terminal assembly 200 of the present invention. Schematic diagram of the terminal block 300, Fig. 4 is a schematic view of the assembly of the embedding block 4, and Fig. 5 is a schematic view of the creation. As shown in FIG. 2-5, the electrical connector of the present embodiment includes a plurality of first terminals 100, a plurality of second terminals 200, a terminal block 300, and a buried block 4A. As shown in FIG. 2, each of the first terminals 100 is an elongated strip of conductive metal, and each of the first terminals 1 further includes a first contact end 11〇 and a first solder end 12〇; wherein the first contact The terminal 110 is for contacting the terminal inserted into the electrical connector, and the first terminal 120 is for soldering to the board. As shown in Fig. 2, the terminal block 300 is a platform-shaped plastic seat body which can be produced by plastic injection molding. The first terminal 1 刖 is embedded in the terminal block 3〇〇 side by side, wherein the middle portion of the first terminal 100 is wrapped in the terminal block 3 (8), the first contact end 11 and the first-welded end 1201 : Out of the terminal block 3〇〇. The first contact end j 1 〇 only needs to be partially exposed on the surface of the terminal block 300 to contact the terminal inserted into the electrical connector; and the first soldering end 12 is exposed to the terminal block 3GG and then extends further outwards. Work on the board (see Figure 2). Referring to Figure 3, the second terminals 2 (10) are formed by metal sheet punching. When the stamping operation is completed, the second terminals 2 are still connected to an outer frame 2〇1, so that the first The two terminals 200 can be moved together with the outer frame 201. The second terminal 2〇〇 connected to the outer frame 2〇1 can be placed together on the terminal block 300. The terminal block 300 is provided with a plurality of positioning slots 310, and the second contact end 210 is placed in the positioning slot 31. Positioning, such that each of the second terminals 2〇〇 is staggered with the first terminals 100, and each of the second terminals 2A includes a second contact end 21〇 and a second soldering end 220, wherein the second contact end 21〇 For contacting the terminal inserted into the electrical connector, the second soldering end 220 is for soldering to the board. Referring to FIGS. 4 and 5, after the second terminal 2〇〇 connected to the outer frame 2〇1 is placed together on the terminal block 300, the outer frame 2〇1, the second terminal 2〇〇, and the terminal block 300 It can be placed in another plastic injection molding mold for secondary plastic injection molding. After the secondary plastic injection molding, a buried block 4〇〇 can be formed and directly formed on the terminal block 3〇〇. And integrated with the terminal block 300. In general, the terminal block 3〇〇 and the embedded block 4〇〇 are both plastic and are made of different plastic materials. After the embedding block 4 is formed, each of the second terminals 200 is buried side by side between the embedding block 4〇〇 and the 3〇〇 terminal block β, wherein the embedding block 400 and the terminal block 300 are only partially embedded. The middle portion of the two terminals is such that at least a portion of the second contact end 21G and the second soldering end 22G are exposed on the surface of the embedding block 4 (10). After the embedding block 400 is formed, the outer frame 201 is removed to form a complete Electrical connector. In the electrical connector of the present invention, the first terminal (10) and the second terminal 2 (10) are both covered by the plastic material, and only the first contact end 11G, the first soldering end 12G, the second contact end 210 and the second are exposed. The soldering end 22G and the like are connected, and the second contact end is arranged above the contact end 11〇 and is staggered with the first contact end 110 (refer to FIG. 5). The embedding block 400 of the present invention has the effect of fixing and insulating the second terminals 21 ' at the same time. Compared with the prior art, the present invention skillfully applies the overmolding technology, and the terminal block 3 (8) and the embedding block 400 are formed. The first terminal 1〇〇 and the second terminal 2〇〇 are covered and fixed therein, and the second terminal 200 is not covered and insulated before being assembled, and the whole process can be automatically produced, “the assembly labor cost is not required; The embedding block 4 is directly formed on the terminal block 300. It is not necessary to design the embedding block 400 and the terminal block 3 to be joined to each other. The mold structure is simple, which not only reduces the manufacturing cost, but also improves the process stability.
