Please refer to Fig. 1, Fig. 1 is an exploded view of the structure of an embodiment of the electric connector cable welding fixture of the present invention, as shown in Fig. The first processing mechanism 15.

The connection methods and functions of each device are described in detail below. The fixing jig for electric connector cable welding in this embodiment is referred to as the jig hereinafter. Wherein, the electrical connector and the cable are welded to form a cable assembly.

The first processing mechanism 15 has a workbench, and the workbench is provided with at least one slot for fixing the electrical connector to perform welding of the electrical connector and the cable.

The second processing mechanism 13 has a base plate provided with at least one joint for fixing the electrical connector, and a detection circuit connected with the joint for short circuit detection of the welded electrical connector.

In this embodiment, the workbench is assembled with the base plate.

The specific function of the first processing mechanism 15 is that the slot hole of the first processing mechanism 15 is used to fix the pin of the independent electrical connector so that the welding of the pin and the inner conductor of the cable, or the slot hole of the first processing mechanism 15 is used It is used to fix the pins in the electrical connector so that the pins can be welded to the inner conductor of the cable.

If the slot holes fix the individual electrical connector pins, after the pins are welded to the inner conductor of the cable, the pins need to be inserted into the matching electrical connector housing, and then the second processing mechanism 13 is used for further welding .

In addition, in this embodiment, the worktable of the first processing mechanism 15 is further provided with at least one groove extending longitudinally along the surface of the worktable for shaping and cutting.

The specific function of the second processing mechanism 13 is that the joint of the second processing mechanism 13 is used to fix the matched electrical connector that has been welded with the inner conductor of the cable so as to weld the housing of the electrical connector and the outer conductor of the cable.

In addition, the detection circuit of the second processing mechanism 13 can simultaneously detect whether there is a short circuit during the welding process of the electrical connector and the cable.

The joints of the second processing mechanism 13 are male/female joints corresponding to various common electrical connectors, including: SMA series, N series, MCX series and TMA series.

Wherein, the circuit schematic diagram of the detection circuit is shown in FIG. 2 .

As shown in FIG. 2 , the detection circuit includes an indicator light for indicating whether there is a short circuit in the welding between the electrical connector and the cable.

In this embodiment, the electric connector is fixed on the corresponding joint, which can avoid the hand-held welding in the prior art, and is convenient and safe to operate, and has a good fixing effect.

Specifically, the electric connector is screwed and fixed on the joint by a threaded connection fixing method.

In this embodiment, the fixture further includes a heat shield 12 disposed under the second processing mechanism 13 for keeping the heat concentrated during the welding process of the electrical connector and the cable.

The power supply 14 disposed on the heat shield 12 is used to provide voltage to the detection circuit.

The base 11 is arranged under the heat insulation board 12 .

The specific operation process of the fixture in this embodiment will be described in detail below.

Firstly, an appropriate amount of solder wire is pre-filled in the pins of the electrical connector. At this time, the pins are individual pins or pins connected to the housing of the electrical connector, and then the pins are fixed in the slots of the first processing mechanism 15 Inside, heat the pins to melt the solder wire, then quickly insert the inner conductor of the cable into the pins to complete the soldering. The method for fixing the pins in the slot holes of the fixture can keep the pins of the electric connector coaxial with the inner conductor of the cable, and is convenient and safe to operate, and can optimize the welding working hours and welding quality at the same time.

Wherein, the slot hole can be adapted to pins of various common electrical connectors.

After the electrical connector pins are welded to the inner conductor of the cable, the electrical connector that has been welded to the inner conductor of the cable is fixed on the joint of the second processing mechanism 13 to weld the housing of the electrical connector and the outer conductor of the cable. During the welding process, the detection circuit can perform synchronous short circuit detection on welding.

In order to prevent the heat from spreading rapidly when the electrical connector and the cable are welded, compared with the traditional metal material fixture, the heat shield 12 can keep the heat concentrated during the welding process of the electrical connector and the cable, thereby avoiding poor welding and reducing Welding time.

Wherein, the heat insulation board 12 and the first processing mechanism 15 are bakelite materials. When welding on the first processing mechanism 15 , the first processing mechanism 15 can also play the function of the heat shield 12 .

Wherein, the base 11 is processed from an aluminum block.

In order to grasp the detection results in time, the detection circuit contains indicator lights, such as LED lights, which can indicate whether there is a short circuit when the electrical connector and the cable are welded, that is, the inner conductor and outer conductor of the cable are respectively welded to the pin and shell of the electrical connector. Check if there is a short circuit. When welding, if the corresponding indicator light is on, it means that the electrical connector and the cable assembly of the cable welding are short-circuited. This setting avoids detection with a multimeter.

To sum up, the advantages of the fixture of the present invention include fixing the electrical connector by threaded connection, fixing the pin of the electrical connector by using the slot method, concentration of welding heat and real-time detection of the cable assembly. Utilizing the jig of the invention can reduce the man-hours for fixing the electric connector, reduce the man-hours for welding the electric connector, reduce the man-hours for short-circuit detection of the cable assembly, and at the same time improve the welding quality and electrical performance index of the cable assembly.
