Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of connectors, and in particular to a Pogo Pin connector. Background Art
[0002] After long-term use, the probes of pogo pin connectors will encounter wear and oxidation problems. If the probes are damaged or corroded during use, the signal channel where the probes are located cannot be used, causing the entire device to stop working and must be replaced. However, the probes in most existing pogo pin connectors cannot be disassembled and replaced. A small number of disassembled pogo pin connectors have structural limitations that make the probes too long or too wide, making them unable to adapt to application scenarios with narrow spaces. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a Pogo Pin connector, which can avoid waste of resources, reduce maintenance costs, and adapt to application scenarios with narrow spaces.
[0004] The present invention is achieved through the following technical solutions:
[0005] A Pogo Pin connector comprises a plurality of probes, a plurality of syringes and a base, wherein the plurality of syringes are arranged side by side on the base, the plurality of probes are arranged one by one with the plurality of syringes, one end of the probe is arranged inside the syringe and detachably connected to the syringe, and the other end is exposed outside the syringe, the end of the syringe away from the probe is used for connecting a cable, an elastic abutment is formed on the syringe, and the elastic abutment is inclined toward the axial direction of the syringe;
[0006] When the probe is inserted into the syringe, the elastic abutment member abuts against the probe, and the elastic abutment member is located within the diameter range of the syringe.
[0007] Furthermore, the plurality of syringes are arranged at equal intervals in the transverse direction and aligned in the longitudinal direction.
[0008] Furthermore, the elastic abutment member is formed by cutting the outer peripheral wall of the syringe.
[0009] Furthermore, one end of the elastic abutment is connected to the syringe, and the other end is suspended to abut against the probe.
[0010] Furthermore, the other end of the elastic abutment member is formed with an arc surface.
[0011] Furthermore, the angle a formed by the tangent line of the arc-shaped surface at the outer side and the radial direction of the syringe is 20° to 30°.
[0012] Furthermore, when the probe is inserted into the syringe, the elastic abutment member abuts against the probe, and the outer arc surface of the elastic abutment member is coplanar with the outer peripheral wall of the syringe.
[0013] Furthermore, a single split groove is formed at the cutting portion of the syringe.
[0014] Furthermore, the width of the single split groove is uniform and the width d of the single split groove is 0.2-0.4 mm.
[0015] Furthermore, when the probe is not inserted into the syringe, an angle b formed by the elastic abutment member and the axis of the syringe is 2° to 4°.
[0016] Compared with the prior art, the advantages of the present invention are:
[0017] 1. By designing the probe and syringe to be detachable, when one or more probes in the Pogo Pin connector are damaged, only the corresponding probe needs to be replaced without replacing the entire Pogo Pin connector. This approach can avoid waste of resources and reduce maintenance costs.
[0018] 2. The probe can be detached by setting an elastic abutment to abut against the probe. When the probe is located inside the syringe, the elastic abutment fixes the probe while the elastic abutment does not exceed the original diameter range of the syringe, which means that more syringes can be arranged in the same space, making the structure of the Pogo Pin connector more compact.
[0019] 3. By cutting the outer wall of the syringe to form an elastic abutment member, there is no need to add additional components to lock the probe, which saves material costs and simplifies the structure of the syringe.
[0020] 4. The friction loss of the elastic abutment member during the insertion of the probe can be reduced by setting the other end of the elastic abutment member to be an arc-shaped surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is a further non-restrictive detailed description of the technical solution of the invention in conjunction with the preferred embodiments and the accompanying drawings. In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings. In addition, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and cannot be understood as limitations on the present invention.
[0029] like Figure 1-Figure 4 As shown, a Pogo Pin connector according to an embodiment of the present invention comprises a plurality of probes 1, a plurality of syringes 2 and a base 4, wherein the plurality of syringes 2 are arranged side by side on the base 4, the plurality of probes 1 are arranged in one-to-one correspondence with the plurality of syringes 2, and one end of the probe 1 is arranged inside the syringe 2 and detachably connected to the syringe 2, and the other end is exposed outside the syringe 2, and the end of the syringe 2 away from the probe 1 is used to connect the cable 5. By designing the probe 1 and the syringe 2 to be detachable, when one or more probes 1 in the Pogo Pin connector are damaged, only the corresponding probe 1 needs to be replaced, without replacing the entire Pogo Pin connector, which can avoid waste of resources and reduce maintenance costs.
[0030] In this embodiment, the plurality of syringes 2 are arranged at equal intervals in the transverse direction and aligned in the longitudinal direction.
[0031] like Figure 3 As shown, an elastic abutment member 3 is formed on the syringe 2, and the elastic abutment member 3 is inclined toward the axis direction of the syringe 2; specifically, when the probe 1 is not inserted into the syringe 2, the angle b formed by the elastic abutment member 3 and the axis of the syringe 2 is 2° to 4°. In this embodiment, the angle b is 2°.
[0032] refer to Figure 3 , Figure 3 The needle barrel 2 is not inserted into the probe 1, and the elastic abutment member 3 is recessed inwards. Figure 2 , Figure 2 The figure shows the state after the syringe 2 is inserted into the probe 1. Figure 4 When the probe 1 is inserted into the syringe 2, the elastic abutment 3 abuts against the probe 1, and the elastic abutment 3 is within the original diameter range of the syringe 2. In this embodiment, when the probe 1 is not inserted into the syringe 2, the elastic abutment 3 is recessed inward, and the probe 1 is stuck by the elastic abutment 3 after being inserted into the syringe 2. The elastic abutment 3 extends outward, but does not exceed the original diameter range of the syringe 2. The probe 1 is detachable by setting the elastic abutment 3 to abut against the probe 1, and when the probe 1 is located in the syringe 2, the elastic abutment 3 fixes the probe 1, and the elastic abutment 3 does not exceed the original diameter range of the syringe 2, which means that more syringes 2 can be arranged in the same space, making the structure of the PogoPin connector more compact.
[0033] When the probe 1 is inserted into the syringe 2 , the elastic abutment member 3 abuts against the probe 1 , and the outer arc surface of the elastic abutment member 3 is coplanar with the outer peripheral wall 20 of the syringe 2 .
[0034] refer to Figure 5 , when the probe 1 is not inserted, the elastic abutment members 3 on all syringes 2 are inclined toward the axis direction of their respective syringes 2; Figure 6 When the syringe 2 is inserted into the corresponding probe 1, the elastic abutment 3 applies elastic pressure to the syringe 2. At the same time, the elastic abutment 3 slowly moves outward after receiving the outward push of the probe 1. When the probe 1 is inserted into place, the position of the elastic abutment 3 on the syringe 2 is as follows: Figure 6 As shown, at this time, the diameter of each syringe 2 is the same, and the elastic abutment member 3 will not interfere with other adjacent syringes 2, thereby avoiding accidental contact.
[0035] The elastic abutment 3 is formed by cutting the outer wall 20 of the syringe 2. In this embodiment, wire cutting is adopted, and a medium-wire wire cutting machine can be used for processing. The processed syringe 2 forms an elastic abutment 3 on its side, and one end of the elastic abutment 3 is connected to the syringe 2, and the other end is suspended to abut the probe 1. By cutting the outer wall 20 of the syringe 2 to form the elastic abutment 3, there is no need to add additional components to lock the probe 1, which saves material costs and simplifies the structure of the syringe 2.
[0036] The other end of the elastic abutment 3 is formed with an arc surface 30, and the angle a formed by the tangent of the arc surface 30 at the outer side and the radial direction of the syringe 2 is 20° to 30°. By setting the other end of the elastic abutment 3 as the arc surface 30, the friction loss of the elastic abutment 3 when inserting the probe 1 can be reduced.
[0037] A single split groove 21 is formed at the cutting portion of the needle cylinder 2. The width of the single split groove 21 is uniform and the width d of the single split groove 21 is 0.2-0.4 mm. The single split groove 21 has a uniform width and is more convenient for machining.
[0038] In this embodiment, the material of the syringe 2 is beryllium bronze.
[0039] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
