Problems solved by technology

[0004] Although there are many factors that lead to the leakage of the compressor, according to the existing market reflections, it is basically concentrated between the interface between the conductive needle 12' and the glass sealing body 13, which is caused by the leakage caused by the pull mark 121
For this reason, the industry can only conduct a comprehensive airtight inspection of the packaged terminals at present, and there is no good fundamental solution

Embodiment 1

[0035] Such as Figure 5-Figure 7 As shown, the outer surface of the conductive needle 12 corresponding to the position penetrating through the installation hole of the metal shell 11 is provided with an anilox knurling surface 122b (can be processed with reference to the anilox knurling standard of GB / T6403.3-2008. Anilox knurling The width H of the flower surface 122b is greater than the depth h of the installation hole, and the mesh of the mesh-shaped recessed part is rhombus.

[0036] In this embodiment, the stretch mark 121 is artificially cut into multiple sections by the textured knurled surface 122b. When the glass is melted into a liquid state, the capillary action generated by the textured knurled surface 122b infiltrates between the conductive needle 12 and the mounting hole of the metal shell 11. gap, and completely fill the recessed portion of the knurled surface 122b, so that the airtightness of the entire terminal is improved and it is not easy to leak.

Embodiment 2

[0038] A rough surface 122a is provided on the outer surface of the conductive pin 12 corresponding to the position where it penetrates through the mounting hole of the metal shell 11, such as Figure 8 shown. Rough surface 122ad roughness above Ry3.0.

[0039] In this embodiment, the rough surface 122a artificially eliminates the pull mark 121. When the glass is melted into a liquid state, the capillary action generated by the rough surface 122a infiltrates the gap between the conductive pin 12 and the mounting hole of the metal shell 11, and completely fills the rough surface. The recessed portion on the surface 122a improves the airtightness of the entire connecting terminal and prevents leakage.

Embodiment 3

[0041] The outer surface of the conductive pin 12 is provided with a number of wire grooves 122c parallel to the circumferential direction of the conductive pin (that is, the angle with the circumferential direction is 0°), as shown in Figure 9 shown.

[0042] In this embodiment, the stretch marks 121 are artificially cut into multiple sections through several wire slots 122c. When the glass is melted into a liquid state, the capillary action generated by the wire slots 122c infiltrates the gap between the conductive pin 12 and the mounting hole of the metal shell 11 and completely fills it. The recessed part of the full wire groove 122c improves the airtightness of the entire terminal and is not easy to leak.

Abstract

The invention discloses an improved connection terminal and an air conditioner compressor containing the connection terminal, comprising a metal shell, a conductive pin penetrating through the installation hole of the metal shell, and a glass seal combining the conductive pin and the metal shell package body, and the surface treatment part is provided on the outer surface of the position where the conductive pin should pass through the installation hole of the metal shell. In the present invention, at least the outer surface of the conductive needle penetrates through the installation hole of the metal shell to form a rough surface, a textured knurled surface, or a wire groove with an angle of 0-85° to the circumferential direction of the conductive needle. In this way, the pull marks are artificially eliminated or cut off, and the capillary action generated by the above structure infiltrates the gap between the conductive pin and the mounting hole of the metal shell when the glass is melted into a liquid state, and completely fills the concave part of the surface treatment part, making the whole The airtightness of the connection terminal is improved, and it is not easy to leak.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to connection terminals for air conditioner compressors. Background technique [0002] In the field of air conditioner compressors, terminal blocks are widely used, such as Figure 1-Figure 3 shown. The connection terminal 1 includes a metal shell 11, a needle-shaped conductive pin 12', and a glass sealing body 13 that encapsulates the conductive pin 12' and the metal shell 11. The connection terminal 1 is hermetically connected to the casing 2 of the compressor through a metal casing 11. Since the internal pressure of the compressor is high when the compressor is in use, the sealing performance of each component is highly required. [0003] During the production process of the conductive needle 12', the thicker steel wire is gradually drawn into a thin wire. During the wire drawing operation, it is inevitable to form a pull mark 121 on the surface of the conductive needle 12' (the ...
