Description

Connector and assembling method thereof

Technical Field

The present disclosure relates to connectors, and particularly to a connector and an assembling method thereof.

Background

The connector is used for realizing signal exchange between two devices, such as an audio signal, a video signal, or a network signal. With the advancement of technology, the need for transmitting a large number of signals is increasing. Therefore, the number of wires in the connector becomes larger. In addition, in order to reduce the volume of the product, the structure of the connector also becomes finer and more complex. In this case, the welding between the wire and the connection terminal becomes more difficult. Taking the sound source line as an example, the sound source line generally includes a double-layer line, a left ground line, a right ground line, a left channel line, and a right channel line. Further, the double-layer wire, the left ground wire and the right ground wire are welded on the bonding pad of the connecting terminal, so that signal transmission is realized.

However, when the pad of the connection terminal is an arc-shaped pad, it may cause a difficulty in the soldering process to be significantly raised. In addition, the three wires are welded at the same position, and are easily overlapped with each other or are obviously protruded out of the connecting terminals, so that subsequent processing fails.

That is, the existing assembly method extremely checks the skill of the operators, and the product is also susceptible to the technical differences of the operators. Therefore, how to reduce the technical difference between operators and provide an assembly method with high efficiency and high yield is an urgent problem in the art.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, a flowchart of a method for assembling a connector according to an embodiment of the application is shown. It should be noted that the order of the steps is not necessarily constant, some steps may be performed simultaneously, omitted or added, and the flowchart is used to describe the steps in a broader and simple manner, and is not intended to limit the order or number of steps in the assembly method of the present application. As shown, the method of assembling the connector includes:

Step S10: and providing a connecting wire, wherein the connecting wire comprises a first ground wire, a second ground wire and a double-layer wire, the double-layer wire is provided with a first area and a second area, and an outer layer wire and an inner layer wire in the first area and the second area are wound with each other along the axial direction.

In some embodiments, the first ground line may be a right ground line corresponding to a right channel line, and the second ground line may be a left ground line corresponding to a left channel line. In some embodiments, the diameter of the first ground wire may be between 0.41mm and 0.31 mm. Of these, the preferred diameter is 0.40mm. The diameter of the second ground wire may be between 0.41mm and 0.31 mm. Of these, the preferred diameter is 0.40mm.

In some embodiments, the first ground wire rotates about a first centerline. That is, the first ground wire is stranded on the first center line. In some embodiments, the first ground wire may be right-hand twisted (S-twisted), and the first ground wire may have a lay length between 2.50mm and 2.10 mm. Among them, the preferable lay length is 2.30mm. In some embodiments, the second ground wire rotates about a second centerline. That is, the second ground wire is stranded on the second centerline. In some embodiments, the second ground wire may be right-hand twisted (S-twisted), and the second ground wire may have a lay length between 2.50mm and 2.10 mm. Among them, the preferable lay length is 2.30mm.

In some embodiments, a double layer wire is used to convey the microphone signal. In some embodiments, the double layer wire may have a diameter between 0.35mm and 0.8 mm. Of these, the preferred diameter is 0.42mm.

In some embodiments, two ends of the connection line are respectively connected with the broadcasting device and the connection terminal. That is, one end of the double-layered wire of the connection wire is adjacent to the broadcasting device, and the other end is adjacent to the connection terminal. In this case, the first region may be a portion of the double-layer wire adjacent to the broadcasting device, and the second region may be a portion of the double-layer wire adjacent to the connection terminal.

In some embodiments, the outer layer wire of the double layer wire rotates about the third centerline. That is, the outer layer wire is stranded on the third centerline. In some embodiments, the outer layer wire may be left-hand (Z-lay) and the lay length of the outer layer wire may be between 4.80mm and 3.80 mm. Among them, the preferable lay length is 4.30mm. In some embodiments, the inner wire of the double wire is rotated about the third centerline. That is, the inner layer wire is stranded on the third centerline. In some embodiments, the inner layer wire may be, but is not limited to, left lay (Z lay), and the lay length of the inner layer wire may be between 1.80mm and 2.20 mm. Among them, the preferable lay length is 2.00mm.

Step S11: the outer layer line is separated from the inner layer line in the second region. That is, only a portion of the outer and inner wires (i.e., the outer and inner wires in the second region) of the entire double-layered wire are separated from each other, and the remaining portion (i.e., the outer and inner wires in the first region) remains twisted on the third center line. Specifically, "separating" means untwisting the outer layer wire and the third center wire and the inner layer wire and the third center wire from one end of the connecting wire and moving the outer layer wire and the inner layer wire away from each other.

Step S12: twisting the first ground wire with the outer wire in the second region.

In some embodiments, the stranded first ground wire and outer wire may have a diameter between 0.51mm and 0.41 mm.

Step S13: twisting the second ground wire with the inner layer wire in the second region.

In some embodiments, the stranded second ground wire and inner layer wire may have a diameter between 0.51mm and 0.41 mm.

Step S14: and welding the stranded first ground wire and the stranded outer wire on the first bonding pad of the connecting terminal. In some embodiments, the method of welding is spot welding. More specifically, spot welding is performed by a spot welding device. It should be noted that the present application is not limited to the use of spot welding, and the welding method recognized by those skilled in the art can be applied to the present application.

Step S15: and welding the stranded second ground wire and the inner layer wire on the first bonding pad of the connecting terminal. Wherein the twisted second ground wire and the inner layer wire are located at one side of the twisted first ground wire and the outer layer wire, and the two wires may be substantially parallel to each other. In some embodiments, the method of welding is spot welding. Compared with manual welding, the welding strength of the welding spot can be improved from 20N to 60N to 47.5 to 60N by the spot welding of the spot welder. That is, manual welding is limited by technical differences of operators, not only the welding strength is unstable, but also may be lower than 45N of the product specification. In contrast, spot welder spot welding can ensure that the quality of each weld is similar and can be stably higher than 45N of the product specification.

In some embodiments, after the steps of soldering the stranded first ground wire and the outer layer wire to the first pad of the connection terminal and soldering the stranded second ground wire and the inner layer wire to the first pad of the connection terminal, the method of assembling the connector further comprises:

step S16: the sleeve is arranged to cover the welded first ground wire and the outer layer wire and the welded second ground wire and the inner layer wire.

In the prior art, the double layer wire, the first ground wire and the second ground wire, which are respectively soldered on the first pad, often interfere with each other due to a small soldering space. In addition, when the soldering technique of the worker is not good, the double-layered wire, the first ground wire, and the second ground wire may overlap each other, so as to protrude excessively above the first bonding pad, thereby making it impossible to perform subsequent processing (i.e., sleeving the sleeve to cover the respective strands). However, the present application recombines the original three-strand wires into two strands (i.e., a twisted first ground wire and an outer layer wire and a twisted second ground wire and an inner layer wire) through steps S10 to S15. As such, even if the diameter of the single strand becomes large (as mentioned above), the total number of strands decreases, and instead can be more easily soldered to the first pad. In addition, the two side-by-side wires are arranged side by side with each other, so that the risk of overlapping to protrude from the first pad is reduced, and thus step S16 can be stably performed. Hereinafter, each step will be explained in detail to make the technical features of the present application more easily understood and clear.

Referring to fig. 2, a flowchart of a method for assembling a connector according to another embodiment of the application is shown. In some embodiments, after the step S12 of twisting the first ground wire and the outer layer wire in the second region, and before the step S14 of welding the twisted first ground wire and the outer layer wire to the first pad of the connection terminal, the assembling method of the connector further includes:

Step S20: and removing the paint on the twisted first ground wire and the twisted outer layer wire by laser. More specifically, the lacquer (or coating) on the first ground wire and the outer wire is removed by a laser so that the conductors located inside the first ground wire and the outer wire are exposed through the removed openings.

Step S21: cutting the twisted first ground wire and the outer wire.

In some embodiments, both step S20 and step S21 may be performed by dedicated fixture. For example, the connecting wires may be placed on the fixing jig, and the strands may be placed in the fixing grooves on the fixing jig to perform wire arrangement. Then, the connecting wire is cut by a cutter after the laser paint is removed.

Step S22: and dipping tin on the twisted first ground wire and the outer layer wire.

Step S23: and welding the stranded first ground wire and the outer wire on the first bonding pad of the connecting terminal.

In some embodiments, step S23 may be implemented by assembling a jig. For example, the assembly jig may have clamping jaws. After the stranded first ground wire and the outer wire are fixed by the clamping jaw, the stranded first ground wire and the stranded outer wire are welded on the first bonding pad of the connecting terminal by spot welding.

Referring to fig. 3, a flowchart of a method for assembling a connector according to another embodiment of the application is shown. In some embodiments, after the step S13 of twisting the second ground wire and the inner wire in the second region, and before the step S15 of soldering the twisted second ground wire and the inner wire to the second pad of the connection terminal, the assembling method of the connector further includes:

Step S30: and removing the paint on the stranded second ground wire and the inner layer wire by laser.

Step S31: cutting the stranded second ground wire and the inner layer wire.

Step S32: and dipping tin on the stranded second ground wire and the inner layer wire.

Step S33: and welding the stranded second ground wire and the inner layer wire on the first bonding pad of the connecting terminal.

In some embodiments, the implementation details of steps S30 to S33 may refer to steps S20 to S23. That is, the steps S30 to S33 may use the same fixture, assembly fixture and implementation method as those of the steps S20 to S23, so details are not repeated.

Referring to fig. 4, a flowchart of a method for assembling a connector according to another embodiment of the application is shown. In some embodiments, the step S11 of separating the outer layer lines from the inner layer lines in the second region comprises the following sub-steps:

Sub-step S110: the outer coating of the second region of the bilayer line is removed to expose the outer layer line and the inner layer line. In some embodiments, the method of removal may be performed by a tool or by a laser.

Substep S111: the outer coating of the first region of the bilayer wire is removed adjacent to the second region to expose the outer layer wire and the inner layer wire. In some embodiments, the method of removal may be performed by a tool, or by a laser. Wherein the removed coating length of the first region may be between 5mm and 15 mm. Of these, 10mm is preferable, but the implementation of this embodiment is not limited.

Substep S112: the outer layer line is separated from the inner layer line in the second region. That is, only the outer layer wire and the inner layer wire in the second region are separated, and the twist between the outer layer wire and the inner layer wire from which the outer coating is removed in the first region is maintained, so that the subsequent processing is facilitated.

Please refer to fig. 5, which is a flowchart illustrating a method for assembling a connector according to another embodiment of the present application. In some embodiments, the connection line may further include a first signal line and a second signal line. In some embodiments, the first signal line may be a right channel line and the second signal line may be a left channel line. In some embodiments, the first signal line rotates about a fourth centerline. That is, the first signal line is stranded on the fourth center line.

In some embodiments, the first signal line may be, but is not limited to being, right-hand (S-lay) and the lay length of the first signal line may be between 2.50mm and 2.10 mm. Among them, the preferable lay length is 2.30mm. In some embodiments, the second signal line rotates about a fifth centerline. That is, the second signal line is stranded on the fifth center line. In some embodiments, the second signal line may be, but is not limited to being, right-hand (S-lay) and the lay length of the second signal line may be between 2.50mm and 2.10 mm. Among them, the preferable lay length is 2.30mm.

In some embodiments, the double layer wire, the first ground wire, the second ground wire, and other strands (to be mentioned later) in the connection wire rotate around the support wire. That is, the double-layer wire, the first ground wire, the second ground wire, and other strands are further twisted on the support wire in addition to being twisted with the first center line, the second center line, and the third center line, respectively. In some embodiments, the plurality of strands described above may be, but are not limited to, right-hand (S-lay) and the lay of the plurality of strands may be between 21.50mm and 28.50 mm.

As shown, in some embodiments, the connection wire 11 may further include a ballistic wire 116, and the ballistic wire 116 is fixed to the connection terminal 10 by dispensing. In the case of the bulletproof yarn 116, the wire connection strength of the connection wire 11 increases from the original 47.5N to 60N to 50N to 62.5N.

As shown in fig. 6, in some embodiments, the connection line 11 may further include a first signal line 113, a second signal line 114, and a supporting line 115, and the two-layer line 110, the first ground line 111, the first signal line 113, the second ground line 112, and the second signal line 114 are sequentially arranged around the supporting line 115 when viewed from an axial direction of the connection line 11. The configurations (e.g., pitches) between the two-layer wire 110, the first ground wire 111, the first signal wire 113, the second ground wire 112, and the second signal wire 114 and the supporting wire 115 may be referred to above, and will not be described herein.

In summary, according to the connector and the assembling method thereof of the present application, the outer layer wire and the inner layer wire of the double-layer wire are separated, and the outer layer wire and the inner layer wire are respectively twisted with the first ground wire and the second ground wire, so that the number of wires at the welding position is changed from three to two. The diameter of the stranded wires is only slightly increased compared to the individual diameters of the wires before stranding, but the number is changed from three to two. That is, the overall diameter is substantially smaller. Therefore, during welding, the two twisted wires are not only easy to process, but also can avoid overlapping or protruding outside the connection terminal. Therefore, the application realizes the assembly method of the connector with high efficiency and high yield.
