Description

Technical Field

[0001] The utility model relates to the technical field of transistor components, in particular to an improved gold-plated pin fixing structure for a metal tube shell. Background Art

[0002] Transistor refers to any single component based on semiconductor materials. Transistor has multiple functions such as detection, rectification, amplification, switching, voltage regulation, signal modulation, etc. Transistor can be used for a variety of digital and analog functions.

[0003] like Figure 4 As shown, it is a schematic diagram of the assembly of the gold-plated transistor housing and the gold-plated pins of the previous generation. The gold-plated pins are fixed in the reserved mounting holes on the transistor housing by filling with insulating plastic rings to establish an electrical connection between the gold-plated pins and the inner cavity of the transistor housing. However, this gold-plated pin fixing structure has the following shortcomings in actual use: since the insulating plastic ring can only limit the radial freedom of the gold-plated pins, when the gold-plated pins are subjected to axial force, the gold-plated pins are prone to offset movement in the transistor housing, resulting in uneven multiple gold-plated pins and abnormal internal circuit connection after force, which directly affects the finished product quality and use stability of the processed transistor.

[0004] In view of this, it is particularly important to design and manufacture a gold-plated pin fixing structure that can stably limit the gold-plated pin to be installed on the transistor housing and improve the connection stability and shock resistance of the transistor during actual use, in the design, manufacturing and actual use of the metal tube shell. Utility Model Content

The right end of the transistor shell is provided with a plurality of stepped sockets facing the gold-plated pins. The left ends of the plurality of gold-plated pins are integrally fixedly connected with limiting rings corresponding to the stepped sockets. A limiting portion for comprehensively limiting the gold-plated pins and installing them on the transistor shell is provided between the right end of the transistor shell and the plurality of gold-plated pins.

[0008] As a further description of the above technical solution:

[0009] The limiting part includes a lower slot opened in the middle of the right end of the transistor housing and connected to multiple stepped sockets, a limiting plug plate vertically movably installed inside the lower slot, and a lower buckle groove equidistantly opened at the lower end of the limiting plug plate and buckled with the gold-plated pin.

[0010] As a further description of the above technical solution:

[0011] The front end and the rear end of the limit plug plate are integrally and fixedly connected with an outwardly protruding anti-deflection block and an anti-deflection groove which is arranged on the right end of the transistor housing and corresponds to the anti-deflection block.

[0012] As a further description of the above technical solution:

[0013] The inner diameter of the lower buckle groove is equal to the outer diameter of the gold-plated pin, and the inner diameter of the lower buckle groove is smaller than the outer diameter of the limiting ring.

[0014] As a further description of the above technical solution:

[0015] A stepped insulating sleeve which fits the inner wall of the stepped jack is sleeved between the gold-plated pin and the limiting ring.

[0016] As a further description of the above technical solution:

[0017] The stepped insulating sleeve is made of vulcanized rubber.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] In the utility model, the original metal tube shell and gold-plated pins are scientifically and rationally improved, a lower slot, a stepped jack, a limiting plug plate and a lower buckle slot are arranged on the transistor shell, and a limiting ring is arranged on the gold-plated pin at the same time, the stepped insulating sleeve can be sleeved between the gold-plated pin and the limiting ring, and then the gold-plated pin can be pre-inserted into the stepped jack through the stepped insulating sleeve, and then the limiting plug plate is buckled downward into the lower slot of the transistor shell, at this time, the axial freedom of the gold-plated pin on the transistor shell can be limited.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 The utility model provides a technical solution: an improved gold-plated pin fixing structure for a metal tube shell, comprising a transistor shell 1 and a plurality of gold-plated pins 2 equidistantly installed at the right end of the transistor shell 1, a plurality of stepped plug holes 102 facing the gold-plated pins 2 are opened at the right end of the transistor shell 1, and the left ends of the plurality of gold-plated pins 2 are integrally fixedly connected with a limiting ring 201 corresponding to the stepped plug hole 102, and a limiting portion for comprehensively limiting the gold-plated pins 2 installed on the transistor shell 1 is provided between the right end of the transistor shell 1 and the plurality of gold-plated pins 2.

[0028] Specifically, Figure 1-3 As shown, the limiting portion includes a lower slot 101 which is opened in the middle of the right end of the transistor housing 1 and is connected to a plurality of stepped sockets 102, a limiting plug plate 3 which is vertically movably installed on the inner side of the lower slot 101, and a lower buckle groove 301 which is equidistantly opened at the lower end of the limiting plug plate 3 and buckled with the gold-plated pin 2, wherein the front end and the rear end of the limiting plug plate 3 are integrally and fixedly connected with an outwardly protruding anti-deflection block 302 and an anti-deflection groove 103 which is opened on the right end of the transistor housing 1 and corresponds to the anti-deflection block 302. The arrangement of the anti-deflection block 302 and the anti-deflection groove 103, on the one hand, improves the stability of the vertical sliding adjustment of the limiting plug plate 3 in the lower slot 101, and on the other hand, reduces the occurrence of lateral displacement or shaking of the limiting plug plate 3 in the lower slot 101.

[0029] At the same time, the inner diameter of the lower buckle groove 301 is equal to the outer diameter of the gold-plated pin 2, which can prevent the gold-plated pin 2 from being displaced or shaken in the lower buckle groove 301. The inner diameter of the lower buckle groove 301 is smaller than the outer diameter of the limit ring 201, which can limit the limit ring 201 from sliding laterally away from the stepped socket 102, thereby comprehensively limiting and fixing the left end of the gold-plated pin 2 in the stepped socket 102 of the transistor housing 1.

[0030] Specifically, Figure 1-3 As shown, a stepped insulating sleeve 4 is provided between the gold-plated pin 2 and the limiting ring 201, and the stepped insulating sleeve 4 is made of vulcanized rubber. On the one hand, the gold-plated pin 2 and the transistor housing 1 can be flexibly insulated and separated to avoid circuit abnormalities after the gold-plated pin 2 is electrically connected. On the other hand, the structural load-bearing stability and shock resistance are improved after the gold-plated pin 2 and the limiting ring 201 are installed in the step socket 102.

[0031] Working principle: When the gold-plated pin 2 needs to be fixed on the transistor housing 1, first, the operator slides the stepped insulating sleeve 4 between the gold-plated pin 2 and the outside of the limiting ring 201. At this time, the connection part between the transistor housing 1 and the gold-plated pin 2 can be insulated and separated. Secondly, the gold-plated pin 2 can be inserted into the stepped socket 102 reserved on the transistor housing 1 through the stepped insulating sleeve 4. When multiple gold-plated pins 2 are installed on the transistor housing 1, the freedom of the gold-plated pin 2 in the Y-axis and Z-axis directions on the transistor housing 1 can be limited. Finally, the limiting plug plate 3 is slid downward into the lower slot 101 of the transistor housing 1, and the lower buckle groove 301 on the limiting plug plate 3 will be buckled between the gold-plated pin 2 and the limiting ring 201, thereby limiting the freedom of the gold-plated pin 2 in the X-axis direction on the transistor housing 1, and the assembly and fixing operation between the gold-plated pin 2 and the transistor housing 1 is completed.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
