As shown in the figure: When the electrical connector of the utility model is manufactured, the first step S100 is to prepare at least one set of wiring (two sets of wiring in this figure): the wiring 10 is composed of a plurality of wires 101, and the outer coating (plastic sheath) 102 of each wire 101 is peeled off to expose the core wire 103 and the ground wire 104 inside the wire 101. After the ground wire 104 is exposed, the ground wire 104 is bent to one side of the outer coating 102 of the wire 101 or adjacent to the outer coating 102.

[0045] Step S102, at least one metal frame (two metal frames in this figure) is prepared: the top 204 of the metal frame 20 has two symmetrical and perforated positioning parts 201, and a slit 202 is formed between the two positioning parts 201. In addition, a support plate 203 is formed at the bottom 205 of the two metal frames 20, and the support plate 203 is bent toward the inside of the two metal frames 20 to the slit 202 (such as Fig.11 After the two metal frames 20 are sleeved on the wires 101 of the two sets of flat cables 10, the ground wires 104 bent from the wires 101 are located on the outer surfaces of the top 204 and bottom 205 of the two metal frames 20 and are electrically connected to the top 204 and bottom 205 of the two metal frames 20 (as shown in FIG. Figure 2 , 10 As shown), the ground signal can be caused to form a ground isolation state on the two metal frames 20 to eliminate noise and prevent the transmitted signal from being interfered.

[0046] Step S104, performing injection molding: injecting plastic material through an injection molding machine to cover the wires 101 of the two sets of flat cables 10 to form a fixing seat 30, the front section 301 of the fixing seat 30 is located between the metal frame 20 and the wires 101 (such as Figure 3 , 10 , 11 ), the rear section 302 of the fixing base 30 is located on the rear side of the two metal frames 20 , so that the fixing base 30 can stably fix the two sets of cables 10 and the two metal frames 20 .

[0047] Step S106, soldering the circuit board: After the injection molding, soldering the circuit board 40 is performed. The circuit board 40 has a signal conductive circuit (not shown). One or both sides of the front end of the circuit board 40 have a plurality of conductive terminals 401 electrically connected to the signal conductive circuit. One or both sides of the rear end of the circuit board 40 have a plurality of electrical pins 402 and a plurality of grounding pins 403. A convex plate 404 extends from the rear end of the circuit board 40. The convex plate 404 is inserted between the wires 101 of the flat cable 10, so that the core wires 103 of the wires 101 are electrically connected to the electrical pins 402 (such as Figure 4 , 8 , 9).

[0048] Step S108, prepare at least one metal shell (two metal shells in this figure): install on the metal shell 50, the two metal shells 50 have two symmetrical through holes 501 on one side, the through holes 501 are correspondingly positioned on the positioning parts 201 of the two metal frames 20, and there is an opening 502 corresponding to the slit 202 between the two through holes 501. In addition, there are a plurality of metal pins 503 at the front end of the metal shell 50, and the metal pins 503 are electrically connected to the grounding pins 403 to form a grounding loop between the wire 101 and the circuit board 40, which can eliminate noise and ground isolation and avoid interference with the transmitted signal. In addition, the wings 504 on both sides of the two metal shells 50 are located on both sides of the two metal frames 20 to prevent the two sides of the metal frame 20 from being squeezed and deformed (such as Figure 5 , 7 , 8, 9, 10, and 11).

[0049] Step S110, performing insulation layer sealing: After the two metal shells 50 are installed, an adhesive tape is used to cover the rear section 302 of the fixing base 30 and the exterior of the two metal shells 50 to form an insulation layer 60 to prevent the connector from short-circuiting (such as Figure 6 , 7 , 8, 9, 10, and 11). In this figure, the insulating layer 60 is a high temperature tape.

[0050] Through the above steps S100 to S110, the manufacturing and installation of the overall electrical connector are completed, so that the ground wire of the electrical connector is bent at the top (upper) and bottom (lower) of the two metal frames 20 to reduce the left and right widths of the electrical connector.

[0051] Further, if Fig.11 , 12 As shown, the utility model changes the multiple metal pins 503 of the metal shell 50 into multiple partitions 505, and the partitions 505 are U-shaped. When the metal shell 50 is installed on the metal frame 20, each partition 505 is correspondingly covered on a single wire 101, and the partitions 505 are electrically connected to the ground pins 403, so that the core wires 103 of the wires 101 can block noise interference on three sides, so that the signals transmitted by the core wires 103 are not affected or interfered by noise, so as to improve the quality of the transmitted signal.

[0052] See also Figures 2 to 11 , which is a schematic diagram of the semi-finished structure of the connector of the utility model. As shown in the figure: the electrical connector of the utility model includes: at least one set of flat cables 10, at least one metal frame 20, a fixing seat 30, a circuit board 40, at least one metal shell 50 and an insulating layer 60.

The conductor 101 has a plurality of core wires 103 and a plurality of ground wires inside. The ground wires 104 are bent to one side of the outer coating layer 102 of the conductors 101 or are adjacent to the outer coating layer.

[0054] The metal frame is two metal frames 20 in the figure, each of the two metal frames 20 has a top 204, and the top 204 has two symmetrical and perforated positioning parts 201, and a slit 202 is provided between the two positioning parts 201. In addition, each of the two metal frames 20 has a bottom 205, and the bottom 205 has a support plate 203, and the support plate 203 is bent toward the inside of the metal frame 20 to the slit 202 (such as Fig.11 As shown in FIG. 2 ), the support plate 203 is used to prevent the metal frame 20 from being crushed or deformed by external forces. After the metal frame 20 is sleeved on the wires 101 of the two sets of flat cables 10, the ground wires 104 bent from the wires 101 are located on the outer surfaces of the top 204 and the bottom 205 of the two metal frames 20 and are electrically connected to the top 204 and the bottom 205 of the two metal frames 20 (as shown in FIG. 2 ). Figure 2 , 10 As shown), this electrical connection method can cause the ground signal to form a ground isolation state on the metal frame 20 to eliminate noise and prevent the transmitted signal from being interfered.

[0055] The fixing base 30 has a front section 301 thereon. The front section 301 is located between the two metal frames 20 and the wires 101 (eg, Figure 3 , 10 , 11), the front section 301 extends backward to form a rear section 302, and the rear section 302 is located on the rear side of the two metal frames 20, so that the fixing seat 30 can firmly fix the two sets of cables 10 and the two metal frames 20. In the drawings, the fixing seat 30 is made of plastic.

[0056] The circuit board 40 has a signal conducting circuit (not shown) thereon. A plurality of conductive terminals 401 electrically connected to the signal conducting circuit are provided on one or both sides of the front end of the circuit board 40. A plurality of electrical pins 402 and a plurality of grounding pins 403 are provided on one or both sides of the rear end of the circuit board 40. A convex plate 404 extends from the rear end of the circuit board 40. The convex plate 404 is inserted between the wires 101 of the two sets of flat cables 10 so that the core wires 103 of the wires 101 are electrically connected to the electrical pins 402 (such as Figure 4 , 8 , 9).

[0057] The metal shell 50, in this figure, is two metal shells 50, and one side surface of the two metal shells 50 has two symmetrical through holes 501, and the two through holes 501 are correspondingly positioned on the positioning portion 201 of the metal frame 20, and there is an opening 502 corresponding to the slit 202 between the two through holes 501. In addition, a plurality of metal pins 503 are provided at the front end of the two metal shells 50, and the metal pins 503 are electrically connected to the grounding pins 403 to form a grounding loop between the wire 101 and the circuit board 40, which can eliminate noise and ground isolation and prevent the transmitted signal from being interfered with. In addition, the wings 504 on both sides of the two metal shells 50 are located on both sides of the two metal frames 20 to prevent the two sides of the two metal frames 20 from being squeezed and deformed (such as Figure 5 , 7 , 8, 9, 10, and 11).

[0058] The insulating layer 60 is attached to the rear section 302 of the fixing base 30 and the exterior of the two metal shells 50 to prevent the connector from short-circuiting (such as Figure 6 , 7 , 8, 9, 10, and 11). In this figure, the insulating layer 60 is a high temperature tape.

[0059] Since the grounding wires 104 of the conductors 101 of the two sets of cables 10 are located on the outer surfaces of the tops 204 and the bottoms 205 of the two metal frames 20 after being bent, and are electrically connected at the tops 204 and the bottoms 205 of the two metal frames 20, this electrical connection method can transmit the grounding signal to the two metal frames 20 and the two metal shells 50 to form a grounding isolation state to eliminate noise and prevent the transmitted signal from being interfered with. At the same time, after the production is completed, the left and right widths of the connector can also be reduced.

[0060] Furthermore, Fig.11 , 12 As shown, the utility model changes the two metal pins 503 of the metal shell 50 into two partitions 505, and the partitions 505 are U-shaped. When the metal shell 50 is installed on the metal frame 20, each partition 505 is correspondingly covered on a single wire 101, and the partitions 505 are electrically connected to the ground pins 403, so that the core wires 103 of the wires 101 can block noise interference on three sides, so that the signals transmitted by the core wires 103 are not affected or interfered by noise, so as to improve the quality of the transmitted signal.
