[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a 20-pin connector according to the present utility model is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.
[0036] Please refer to Figures 1-9 A 20-pin connector, comprising:
[0037] Conductor assembly 100, which is provided with several conductors. Each conductor assembly 100 includes a needle body 110 and a tail plug 120 from top to bottom. The needle body 110 and the tail plug 120 are nested and inserted. The connection between the needle body 110 and the tail plug 120 is wrapped with a connecting sleeve 130. The outer wall of the connecting sleeve 130 is provided with a slot 131. The tail plug 120 and the connecting sleeve 130 also have a limiting notch 123 that opens to the side.
[0038] The base 200 is made of insulating material and has several insertion holes 210. The connecting sleeve 130 and the tail plug 120 are both disposed in the insertion holes 210. The needle body 110 extends upward from the insertion hole 210. The insertion hole 210 includes a lower channel 211 and an upper channel 212 from bottom to top. One side of the upper channel 212 is connected to a spring arm 230 groove 220. A spring arm 230 is provided in the spring arm 230 groove 220. A slot 131 protrudes from the spring arm 230 groove 220. The spring arm 230 is provided with a limiting protrusion 231 that matches the slot 131. When the limiting protrusion 231 is disengaged from the slot 131, the spring arm 230 has a restoring force. A slot 280 is also provided between the lower channel 211 and the upper channel 212. The slot 280 has at least one horizontal insertion port.
[0039] The limiting assembly includes a first outer plate 310, a second outer plate 320, and an inner plate 330. Both the first outer plate 310 and the second outer plate 320 are provided with limiting channels 311 that are adapted to the needle body 110. One end of the first outer plate 310 is provided with a first connecting part 312 and the other end is provided with a second connecting part 313. The base body 200 is provided with a third connecting part 240. The inner plate 330 is inserted into the slot 280 from the horizontal insertion port and has a fourth connecting part 331 extending out of the slot 280. The first connecting part 312 and the third connecting part 240 are detachably connected, and the second connecting part 313 and the fourth connecting part 331 are detachably connected. The first outer plate 310 fastens and fixes the second outer plate 320 to the base body 200. The inner plate 330 is provided with a limiting protrusion 332 extending into the limiting notch 123.
[0040] The conductor assembly 100 is a split type, consisting of a tail plug 120 and a needle body 110 connected together. A connecting sleeve 130 covers the connection point, serving two purposes: firstly, to enhance the stability of the connection between the tail plug 120 and the needle body 110; and secondly, to cooperate with the spring arm 230. The limiting protrusion 231 on the spring arm 230, held by the elastic force of the spring arm 230, prevents axial movement of the conductor assembly 100. A limiting component is also provided, with a limiting protrusion 332 on the inner plate 330. The limiting protrusion 332 engages with the limiting notch 123 between the tail plug 120 and the connecting sleeve 130, restricting axial movement of the conductor assembly 100. The limiting protrusion 332 also has a first outer plate 310 and a second outer plate 320. The limiting channels 311 in the first and second outer plates 310 and 320 improve the stability of the needle body 110 and allow for easier setting of the needle body 110's extension length. When it is necessary to remove the conductor assembly 100, first separate the first outer plate 310 from the inner plate 330, remove the inner plate 330 through the horizontal socket, and then move the spring arm 230 to disengage the limiting protrusion 231 from the slot 131, thereby allowing the conductor assembly 100 to be removed for replacement or maintenance.
[0041] Please refer to Figure 5 The lower part of the base 200 is also provided with an external connecting portion 250. The external connecting portion 250 is used to connect with other components. Preferably, the external connecting portions 250 are arranged symmetrically or in a circular array, and in particular, the external connecting portions 250 are arranged diagonally. The external connecting portion 250 can use connecting holes to connect with other components by screws, or the external connecting portion 250 can use snap-fit pins, which can be integrally formed with the base 200.
[0042] Please refer to Figure 7 The upper end of the tail plug 120 is a flexible sleeve 121, and the lower end is a flexible slot 122. The flexible sleeve 121 elastically wraps around the pin body 110. The flexible slot 122 is plugged into and connected to the male end of another electrical connector. Generally, a limiting notch 123 is provided below the flexible sleeve 121.
[0043] Please refer to Figure 6 The connecting sleeve 130 is riveted to wrap the elastic sleeve 121. Preferably, the connecting sleeve 130 is provided with riveting feet at both the upper and lower ends.
[0044] Please refer to Figure 5 The second outer plate 320 has a protrusion 321 extending downward along the limiting hole 311, which is adapted to the opening of the insertion hole 210. By setting the protrusion 321, the accuracy of the installation position can be ensured and the stability after installation can be improved.
[0045] Please refer to Figure 1The edge of the second outer plate 320 is provided with a positioning protrusion 322, and the base 200 is provided with a positioning groove 260 or positioning hole that matches the positioning protrusion 322. This facilitates installation and maintains stability after installation.
[0046] Please refer to Figure 5 The first connecting part 312 and the second connecting part 313 are both protruding posts 3121, and the protruding posts 3121 are provided with a first snap-fit part 3122. The third connecting part 240 and the fourth connecting part 331 are both elastic inserts 3311, and the elastic inserts 3311 are provided with a second snap-fit part 3312. The first snap-fit part 3122 and the second snap-fit part 3312 are engaged. The snap-fit connection is convenient and simple to install and remove.
[0047] Please refer to Figure 2 The base 200 is provided with a clearance groove 270 that is adapted to the protrusion 3121, reducing the overall space occupied.
[0048] Preferably, the second outer plate 320 is made of a flexible insulating material. Preferably, the second outer plate 320 is made of rubber. Specifically, there is an axial gap between the first connecting portion 312 and the third connecting portion 240, and an axial gap between the second connecting portion 313 and the fourth connecting portion 331. This allows the extension length of the needle body 110 to be adjustable within a certain range.
[0049] Generally, the conductor assembly 100 has 20 groups, or 20 pins, and the 20 groups of conductor assemblies 100 are divided into three rows, namely 7 in the first row, 7 in the second row, and 6 in the third row; similarly, the limiting protrusions 332 of the inner plate 330 have three lines and extend in the opposite direction to the opening direction of the slot 280.
[0050] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.
[0051] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0052] In summary, this utility model provides a 20-pin connector with a split conductor assembly, consisting of a tail plug and a pin body. A connecting sleeve surrounds the connection point, enhancing the stability of the connection between the tail plug and the pin body, and also engaging with a spring arm. A limiting protrusion on the spring arm, held in place by the spring arm's elastic force, prevents axial movement of the conductor assembly. A limiting component is also provided, with a limiting protrusion on its inner plate. This protrusion engages with a limiting notch between the tail plug and the connecting sleeve, restricting axial movement of the conductor assembly. The limiting protrusion also includes a first outer plate and a second outer plate. The limiting channels in the first and second outer plates improve the stability of the pin body and allow for easier setting of the pin extension length. When the conductor assembly needs to be removed, the first outer plate is first separated from the inner plate, the inner plate is removed through the horizontal insertion port, and then the spring arm is moved to disengage the limiting protrusion from the slot, allowing the conductor assembly to be removed for replacement or maintenance.
