Description

Technical Field

[0001] The utility model relates to the technical field of plug pins, in particular to a plug pin contact piece. Background Art

[0002] Pin contacts, also known as pins, are a type of electrical connector. Their primary function is to connect circuits by mating with socket contacts. They offer advantages such as easy installation, reusability, reliable contact, and stable electrical performance, making them widely used in various electrical devices and systems.

[0003] Bent pin contacts, that is, pin contacts with bent pins, are mainly used to achieve electrical interconnection with vertical printed circuit boards. In the existing technology, in order to achieve a 90° transition of the internal conductor, the commonly used solution for bent pin contacts is: vertical U-shaped welding. That is, a U-shaped groove is set at the upper end of the terminal, and a small cylinder is set at the tail of the conductor. And a small circular hole is set at the rear end of the outer conductor. During the assembly process, the inner conductors are first installed into the interior of the outer conductor in sequence, and the welding part of the inner conductor, that is, the rear end of the small cylinder, is exposed in a position visible from the small circular hole of the outer conductor. After the inner conductor is assembled in place, the U-shaped groove of the terminal is inserted into the outer conductor from the rear bottom of the outer conductor with the U-shaped groove facing upwards, and the U-shaped groove at the upper end of the terminal and the rear end of the small cylinder are inserted into place. Then, a manual electric soldering iron is used to pass through the small circular hole at the rear of the outer conductor to weld the U-shaped groove and the small cylinder. After welding is completed, a plug is finally installed at the rear end of the outer conductor.

[0004] While the above solution achieves basic functionality and has been widely used in a certain product line, existing curved pin contacts have the following drawbacks: Due to structural limitations, the 90° transition of the conductor requires soldering, which involves inserting the solder into a small circular hole. This is not only difficult to operate but also has poor workability. Furthermore, this soldering method carries the risk of "cold solder joints," resulting in low reliability for the curved pin contacts.

[0005] A Chinese invention patent application, published on April 15, 2009, and bearing publication number CN101409411A, discloses a curved self-locking connector comprising a housing, a contact head, a pin, an insulator, a shell, a spring, a compression sleeve, a connecting sleeve, a cover, and steel balls. The insulator and its inner holes are respectively fitted over the pins, while the outer diameters of the insulator and its outer diameter are respectively fitted into the inner hole of the shell. One end of the contact head is inserted between the insulator and the shell, and the connecting sleeve is fitted into the shell. The springs are respectively disposed in the cavity between the connecting sleeve and the shell, and several steel balls are respectively disposed in small holes at one end of the shell. This invention application utilizes a structure in which two insulators clamp the pin, preventing the pin from being pulled out. However, the pin still requires welding to achieve a 90-degree transition between the conductors. Furthermore, the welding operation still requires removing the rear cover of the shell to expose a small hole, through which a welding tool is inserted into the shell, making the operation difficult and poor in welding processability. Utility Model Content

[0014] Furthermore, in order to enable the outer insulating sleeve to be installed in a suitable position inside the outer conductor, the front end of the outer insulating sleeve is provided with an inner boss that cooperates with the front end of the intermediate conductor to limit the position in the front-to-back direction; the outer periphery of the rear end of the outer insulating sleeve is provided with an outer boss, and the inner rear part of the outer conductor is provided with a step surface that cooperates with the outer boss to limit the position in the front-to-back direction.

[0015] Furthermore, in order to enable the outer conductor, the intermediate conductor and the center conductor to simultaneously conduct signals to external components, an outer conductor pin perpendicular to the main axis of the outer conductor is provided on the lower side of the rear end of the outer conductor. The main axis of the outer conductor extends in the front-to-back direction, and the outer conductor pin is parallel to the lower part of the center conductor bending pin or the lower part of the intermediate conductor bending pin.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figures 1 to 12As shown in the figure, the bent pin contact piece described in Example 1 of the present invention comprises an outer conductor 7 with a window at the rear end and an inner conductor with a bent pin. The inner conductor is inserted into the inner portion of the outer conductor 7 from the rear end so that the bent pin is located at the rear of the outer conductor 7; an insulator is provided between the outer conductor 7 and the inner conductor. Figure 1 and Figure 3 As shown, the outer conductor 7 is a shell with a cavity inside. In this embodiment, the bent pin contact is a 1553B pin contact; the main body of the shell is a rotating body, and the main axis of the main body extends along the front-to-back direction. Figure 4 As shown, the tail of the main body is connected to the bent portion. The rear end window of the outer conductor 7 refers to the rear side and the lower side of the bent portion are provided with a fully open window. The end of the bent portion is provided with an outer conductor pin 71, as shown in FIG. Figure 2 As shown. The outer conductor pin 71 and the inner conductor bent pin both have the function of signal conduction, so that the pin contact can realize the conduction of different signals at the same time when used. In this embodiment, as Figure 1 As shown, the inner conductor is provided with a 90-degree bend; the angle between the outer conductor pin 71 and the main axis of its main body is also 90 degrees. In other embodiments, the inner conductor may be provided with a bend at other angles, and the angle between the outer conductor pin 71 and the main axis of its main body may also be other angles. The outer conductor pin 71 is also parallel to the lower portion of the bend. The fully open rear end of the outer conductor 7 allows the inner conductor with the bend to be easily inserted into the outer conductor 7 from the rear end. This avoids the difficulty of welding caused by a 90-degree soldering transition. Furthermore, the fully open rear end of the outer conductor 7 avoids the difficulty of assembling the bend.

[0042] Furthermore, if Figure 1 and Figure 3 As shown, the inner conductor includes a central conductor 11 coaxially arranged with the outer conductor 7, that is, the central conductor 11 is coaxially arranged with the main body of the outer conductor 7. Figure 7 As shown, center conductor 11 comprises a center conductor body and a center conductor bend pin 111 disposed at the rear end of the center conductor body. The center conductor body facilitates insertion into the main body of outer conductor 7, while the center conductor bend pin 111 is disposed at the rear end to facilitate signal conduction. Furthermore, the center conductor body and center conductor bend pin 111 are an integrated structure, eliminating the need for welding between the center conductor body and center conductor bend pin 111. This avoids the difficulties associated with welding at the conductor transition point and poor workability, thereby improving the reliability of the pin contact.

[0043] Example 2 is different from Example 1 in that Figures 1 to 3 As shown, the inner conductor further includes an intermediate conductor 9 disposed between the central conductor 11 and the outer conductor 7 , and an intermediate conductor bending pin 91 is provided at the rear end of the intermediate conductor 9 .

[0044] Furthermore, if Figure 5 and Figure 6 As shown, the intermediate conductor 9 comprises an intermediate conductor barrel 92 sleeved around the center conductor 11 and two intermediate conductor benders 91 disposed at the rear end of the intermediate conductor barrel 92. The cylindrical structure of the intermediate conductor barrel 92 facilitates coaxial assembly with the outer conductor 7 and the center conductor body. After the center conductor 11 and the intermediate conductor 9 are assembled, the two intermediate conductor benders 91 are positioned on either side of the center conductor benders 111. The intermediate conductor 9 and the intermediate conductor benders 91 are also integrally constructed, eliminating the need for welding between the center conductor body and the center conductor benders 111. This further avoids the difficulties associated with difficult welding operations and poor workability at the conductor transition point, further improving the reliability of the pin contact.

[0045] The center conductor looper 111 and the intermediate conductor looper 91 each include a horizontal portion and a vertical portion formed at a 90-degree angle. The vertical portion is connected to the rear end of the horizontal portion and extends downward. The outer conductor pin 71 is parallel to the lower portion of the center conductor looper 111 or the lower portion of the intermediate conductor looper 91, which means that the outer conductor pin 71 is parallel to the vertical portions of the center conductor looper 111 and the intermediate conductor looper 91.

[0046] Example 3 is different from Example 2 in that Figure 1 and Figure 3 As shown, the insulator includes an inner insulating sleeve 10 and an outer insulating sleeve 8. The inner insulating sleeve 10 is disposed between the center conductor 11 and the intermediate conductor 9, and the outer insulating sleeve 8 is disposed between the intermediate conductor 9 and the outer conductor 9. The inner insulating sleeve 10 is sleeved outside the center conductor body, the intermediate conductor cylinder 92 is sleeved outside the inner insulating sleeve 10, and the outer insulating sleeve 8 is sleeved outside the intermediate conductor cylinder 92. Through the center conductor 11, the intermediate conductor 9, and the outer conductor, three layers of signal conduction are achieved. At the same time, the inner insulating sleeve 10 disposed between the center conductor 11 and the intermediate conductor 9, and the outer insulating sleeve 8 disposed between the intermediate conductor 9 and the outer conductor 9, respectively, prevents mutual conduction between the three signals, thereby improving the signal transmission function of the pin contact of the present invention.

[0047] Example 4 is different from Example 3 in that Figure 1 and Figure 3 As shown, the inner side of the intermediate conductor cylinder 92 is provided with a stepped hole with a small front end and a large rear end that matches the outer periphery of the inner insulating sleeve 10. In this embodiment, the inner side of the intermediate conductor cylinder 92 is provided with a three-level stepped surface on the matching surface with the inner insulating sleeve 10, including a small ring surface, a middle ring surface and a large ring surface that are coaxially connected. The inner diameter of the small ring surface is smaller than the inner diameter of the middle ring surface, and the inner diameter of the middle ring surface is smaller than the inner diameter of the large ring surface. The inner insulating sleeve 10 is a deformable sleeve made of a deformable material. And, as shown in FIG. Figure 7As shown, the outer periphery of the center conductor body of the center conductor 11 is also provided with an adapted step surface so that the center conductor body of the center conductor 11 is inserted into the extruded inner insulating sleeve 10, and the inner insulating sleeve 10 is extruded so that the outer periphery of the inner insulating sleeve 10 is pressed tightly into the step hole.

[0048] Example 5 is different from Example 4 in that Figure 1 and Figure 3 As shown, an inner ring platform is provided on the inner side of the intermediate conductor cylinder 92 near the front end, and the inner ring surface of the inner ring platform is the aforementioned small ring surface. Figure 10 and Figure 11 As shown, an L-shaped groove is provided on the outer side of the front end of the inner insulating sleeve 10. The L-shaped groove mates with the inner ring platform, so that after the inner insulating sleeve 10 is inserted into the intermediate conductor cylinder 92, the front end of the inner insulating sleeve 10 is flush with the side of the inner ring platform away from the intermediate conductor looper 91, i.e., the outer side surface. Furthermore, the L-shaped groove of the inner insulating sleeve 10 mates tightly with the inner annular surface and inner side surface of the inner ring platform. The L-shaped groove mates with the inner ring platform, allowing the inner insulating sleeve 10 to be positioned properly.

[0049] Example 6 is different from Example 4 in that Figure 1 As shown, the front end of the outer insulating sleeve 8 is provided with an inner boss, and the inner side surface of the inner boss abuts the front end of the intermediate conductor 9, that is, the inner boss and the front end of the intermediate conductor 9 are matched in the front-to-back direction to limit the installation of the intermediate conductor 9.

[0050] like Figure 8 and Figure 9 As shown, the outer insulating sleeve 8 has an outer boss on its rear periphery, and the inner rear portion of the outer conductor 7 has a stepped surface. Specifically, the inner side of the outer conductor 7 has a first annular surface that mates with the main portion of the outer insulating sleeve 8, and the inner rear portion of the outer conductor 7 has a second annular surface that mates with the outer periphery of the boss. The second annular surface has a larger diameter than the first annular surface. A stepped surface is formed where the second annular surface joins the first annular surface. The front side of the outer boss abuts against this stepped surface, effectively limiting the front-to-back position of the outer insulating sleeve 8.

[0051] Example 7 is different from Example 1 in that Figures 1 to 3 As shown, the rear end of the outer conductor 7 is slidably connected to a rear cover 6. The rear cover 6 is used to close the rear end window of the outer conductor 7.

[0052] Furthermore, a matching slider and a sliding groove are provided between the rear cover 6 and the rear end of the outer conductor 7. Specifically, Figure 3 and Figure 4 As shown, the rear end of the outer conductor 7 is provided with a vertical outer conductor slot 72, and the upper end of the outer conductor slot 72 is open. Figure 10As shown, both sides of the rear cover 6 are provided with rear cover sliders 61 that fit with the outer conductor slide groove 72. The rear cover 6 is slid into the outer conductor slide groove 72 from the upper end open outer conductor slide groove 72 through the rear cover sliders 61, thereby closing the rear side of the outer conductor 7.

[0053] Example 8 differs from Example 7 in that limiting protrusions 62 are provided on both sides of the upper portion of the rear cover 6, and a limiting groove that cooperates with the limiting protrusions 62 is provided at the rear end of the outer conductor 7. In this embodiment, a limiting protrusion 62 is provided on each side of the upper portion of the rear cover 6, parallel to the rear cover slider 61. The two limiting protrusions 62 each protrude toward the sides of the outer rear cover 6, and the limiting protrusions 62 are located on the rear side of the rear cover slider 61. A limiting groove 72 that cooperates with the limiting protrusion 62 is provided at a corresponding position on the rear end of the outer conductor 7, that is, at the upper portion of the outer edge of the slide. The upper and lower sides of the limiting protrusion 62 are provided with smooth inclined surfaces, so that when the rear cover 6 slides up and down into or out of the slide, the limiting protrusion 62 can slide into or out of the limiting groove 72. When the rear cover 6 is slid from top to bottom and inserted into place, the protrusion 62 slides into the limiting groove 72, which not only serves to locate the installation position of the rear cover 6, but also serves to verify whether the rear cover 6 is slid into place.

[0054] Embodiment 9 differs from embodiment 1 in that the rear end of the outer conductor 7 is connected to a rear cover by gluing or soldering.

[0055] Example 10, a method for assembling the bent pin contact of the present invention, comprising the following steps:

[0056] 1. First, prepare the finished outer conductor 7, outer insulating sleeve 8, intermediate conductor 9, inner insulating sleeve 10 and center conductor 11;

[0057] 2. First, install the outer insulating sleeve 8 into place from the rear end of the outer conductor 7. Then, position the intermediate conductor cylinder 92 of the intermediate conductor 9 forward and backward, and make sure that the lower part, i.e., the vertical part, of the intermediate conductor bending pin 91 is aligned with and parallel to the outer conductor pin 71 of the outer conductor 7. Then, install the intermediate conductor cylinder 92 into the outer insulating sleeve 8, so that the front end of the intermediate conductor cylinder 92 is tightly against the inner boss at the front end of the outer insulating sleeve 8.

[0058] 3. Then, insert the inner insulating sleeve 10 into the middle conductor 9. After it is in place, align the pins at the rear end of the center conductor 11 with the middle conductor looper 91 or the outer conductor 71, and keep the center conductor looper 111 parallel to the middle conductor looper 91 before inserting it into the inner insulating sleeve 10.

[0059] 4. Then, glue is poured into the outer conductor 7 for potting and fixing, so that the outer conductor 7, the outer insulating sleeve 8, the intermediate conductor 9, the inner insulating sleeve 10, and the center conductor 11 are fixed into a whole. In another embodiment, other structures or methods can be used for fixing;

[0060] 5. Finally, the rear cover 6 is assembled from top to bottom at the rear end of the outer conductor 7 using the rear cover slider 61 on the rear cover 6 and inserted into the outer conductor slot 72 at the rear end of the outer conductor 7. The rear cover slider 61 and the outer conductor slot 72 are secured to the rear cover 6 using an interference fit. In another embodiment, the rear cover 6 and the outer conductor 7 can be secured to the rear cover 6 by gluing or soldering.
