Description

Technical Field

[0001] The present invention relates to the field of connectors, and particularly to LVDS connectors.

Background Art

[0002] In the prior art, LVDS connectors are widely applied to the connection between a circuit board and a host computer. In the actual manufacturing process, after the terminal injection molding of the connector is completed and assembled with a metal casing, it is sent to the next process operator. Before the connector is connected to the host, it is necessary to connect a lead wire. The prior art solution for this process is as follows. A material band shown in FIG. 6 is extruded by a pressing module, and the position of the conductive pins on the material band is determined by the terminal positions where each connector needs to be grounded. However, since the performance of the connectors is different, the terminal positions that need to be grounded are also different. Therefore, different connectors need to open new molds and extrude terminals at different positions. Then, the entire material band is placed inside the connector, and the material band is welded inside the metal casing by HOT BAR welding, and a lead wire is welded to the terminals that are not grounded. The biggest problem with the above method is that it is not highly flexible. Since the number of terminals is relatively large and different positions are grounded, it is necessary to open and weld a relatively large number of molds, which greatly increases the cost.

Modes for Carrying Out the Invention

[0015] The following, in combination with the drawings in the embodiments of the present invention, clearly and completely describes the technical solutions in the embodiments of the present invention.

[0016] As shown in FIGS. 1, 2, and 3, the present invention proposes an LVDS connector, which includes a metal casing 1. An insulating body 2 is provided inside the metal casing 1, and the metal casing includes a first casing 5 and a second casing 6. First engaging portions 7 are respectively provided on both sides in the length direction of the first casing 5, and second engaging portions 8 are respectively provided on both sides in the length direction of the second casing 6. The first engaging portion 7 is pressed outside the second engaging portion 8, and the first engaging portion 7 and the second engaging portion 8 are fitted to each other to form an accommodation chamber 9, and are located on both sides in the length direction of the insulating body 2. The insulating body 2 is located between the first casing 5 and the second casing 6 and is firmly fixed. By arranging a positioning strip 15 on the insulating body 2, the first casing 5 is pressed against the positioning strip 15, and the positioning strip 15 is pressed above a plurality of sets of terminals 3. The positioning strip 15 ensures the tightness of the connection between the first casing 5 and the second casing 6 and improves the connection between the metal casing and the insulating body 2.

[0017] The engaging portions on both sides position the insulating body 2 in the length direction. The first engaging portion 7 has a square structure with an opening, and the second engaging portion 8 also has a square structure with an opening, and the two engage with each other. The two sets of opening structures form an accommodation chamber 9, which is used for inserting the driving rod 10. The driving rod 10 forms insertion feet by bending both ends of the rod body and is inserted into the accommodation chamber 9. In order to further increase the stability of the connection and operation of the driving rod 10, a piercing portion is provided on the first engaging portion 7. The piercing portion is pushed into the accommodation chamber 9 and pressed against the side wall of the driving rod 10 to ensure a stable connection of the end of the driving rod 10 inside the accommodation chamber 9. Openings are provided on both sides in the length direction of the metal casing. One side of the insulating body 2 protrudes from the opening, and one end of the corresponding terminal 3 on the other side also protrudes from the opening, which is used for inserting into an electrical connector and conducting with the terminal 3 on the insulating body 2. The first casing 5 is provided with a warping portion 11 at the opening position, which is used to enhance the connection tightness with the opposing connector. The opening on the other side is used for inserting a lead wire and is welded to the internal terminal 3.

[0018] A plurality of sets of terminals 3 are arranged and fitted in the insulating body 2. The terminals 3 are fitted into the insulating body 2 and the surfaces are exposed from the insulating body 2. According to the grounding requirement of the connector, conductors 4 are electrically connected to the terminals 3 at different positions. The conductors 4 are electrically connected to the metal casing. As shown in FIGS. 4 and 5 (the connection positions of the conductors and the terminals are not limited to the positions disclosed in this embodiment and may be any positions), the conductor 4 includes a first horizontal segment 12 and a second horizontal segment 13. An arc-shaped segment 14 is provided between the first horizontal segment 12 and the second horizontal segment 13. The first horizontal segment 12 is pressed against the terminal 3 to ensure crimping and close contact between the two. The second horizontal segment 13 is electrically connected to the second casing 6 and can be welded to the second casing 6 by laser welding. Moreover, an arc-shaped segment 14 is provided. The arc-shaped segment 14 corresponds to the height difference between the insulating body 2 and the second casing 6 and is designed to be in close contact with the gap between the two, ensuring the close connection between the first horizontal segment 12 and the terminal 3. The contact of the second horizontal segment 13 is flatter and more convenient for welding. As shown in FIG. 5, the welding position of the conductor and the second casing is at X, close to the end position.

[0019] A protrusion block 16 is provided between adjacent terminals 3 and is used to partition between adjacent terminals 3. When welding the lead wire and the terminal 3, it facilitates the positioning of the lead wire and avoids short circuit connection between each other.

[0020] In addition, the following is to be described: The conductor 4 has a single structure. After the terminal 3 is welded to the metal casing 1, the conductors 4 are respectively welded to the second casing 6 individually, and are moved to the positions requiring corresponding grounding by a robot arm and connected individually to improve stability.

[0021] This embodiment also discloses an automated welding process for an LVDS connector, including the following. The structure of the conductor includes a first horizontal segment 12, an arc-shaped segment 14, and a second horizontal segment 13. It is possible to directly purchase a flat copper wire, directly press and bend it by a press forming process, or use other processes that can form the above structure, not limited to the above process. In this solution, there is no need to open a mold for pressing a material band for forming a plurality of pins. When a plurality of terminals at any position among the plurality of terminals of the connector need to be grounded, the conductor 4 is grasped one by one by the grip of the robot arm, and the first horizontal segment 12 of the conductor 4 is placed on the terminal 3 that needs to be grounded. At the same time, the second horizontal segment 13 is pressed against the second casing 6, and the conductor 4 and the second casing 6 are welded and fixed one by one by a laser welding facility. The positions where the conductor 4 needs to be connected are preset by a program. Under program control, the robot arm can accurately move to the specified position and accurately place the grasped conductor 4 on the terminal 3. Moreover, by laser welding, the welding efficiency is greatly improved, the structure of the conductor 4 is unified, and the mold opening cost of the press mold is reduced.
