This form is not only troublesome to assemble, but also causes a mess in the space of the sensor housing, which is not conducive to heat dissipation, assembly, and later disassembly and maintenance.

[0004] Therefore, a technology is urgently needed to solve the above technical problems. Utility Model Content

[0011] After the first plug pin and the second plug pin are vertically inserted into the first slot and the second slot from top to bottom, they are respectively limited and clamped by the first slot and the second slot.

[0013] After the first plug pin is plugged into the first slot, the first plug pin plugging portion can be limited and clamped by the first slot, and the first plug pin extension portion extends into the cavity of the plug support seat;

[0014] After the second plug pin is plugged into the second slot, the second plug pin plugging portion can be limited and clamped by the second slot, and the second plug pin extending portion extends into the cavity of the plug support seat.

[0015] Furthermore, the length formed by the first pin extension portion and the second pin extension portion is smaller than the inner diameter of the plug-in support seat; the length formed by the first pin plug-in portion and the second pin plug-in portion is larger than the inner diameter of the plug-in support seat, and not larger than the outer diameter of the plug-in support seat.

DETAILED DESCRIPTION

[0031] The utility model is further described in detail below based on the accompanying drawings and embodiments. 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.

[0032] like Figure 1 and 2As shown, the present invention provides a signal conditioning circuit board limit plug-in mechanism for a pressure sensor, comprising a signal conditioning circuit board 1 and a plug-in support seat 2, wherein the bottom side of the signal conditioning circuit board 1 is provided with mutually symmetrical first pins 3 and second pins 4;

[0033] The plug support seat 2 is cylindrical and includes a cavity for inserting the first plug pin 3 and the second plug pin 4; a first slot 5 and a second slot 6 corresponding to the first plug pin 3 and the second plug pin 4 are provided along the top of the plug support seat 2;

[0034] A first pin limiting groove 7 is provided on the first pin 3, and the first pin limiting groove 7 extends to the bottom end of the first pin 3; the first pin limiting groove 7 is used for plugging and limiting with the first slot 5;

[0035] A second pin limiting groove 10 is provided on the second pin 4, and the second pin limiting groove 10 extends to the bottom end of the second pin 4; the second pin limiting groove 10 is used for plugging and limiting with the second slot 6;

[0036] After the first plug pin 3 and the second plug pin 4 are vertically inserted into the first slot 5 and the second slot 6 from top to bottom, they are respectively limited and clamped by the first slot 5 and the second slot 6.

[0037] like Figure 3 and 4 As shown, in this embodiment, the first pin limiting groove 7 divides the first pin 3 into a first pin plug-in portion 8 and a first pin extension portion 9, and correspondingly, the second pin limiting groove 10 divides the second pin 4 into a second pin plug-in portion 11 and a second pin extension portion 12;

[0038] After the first plug pin 3 is plugged into the first slot 5, the first plug pin plugging portion 8 can be limited and clamped by the first slot 5, and the first plug pin extension portion 9 extends into the cavity of the plug support seat 2;

[0039] After the second plug pin 4 is plugged into the second slot 6 , the second plug pin plugging portion 11 can be limited and clamped by the second slot 6 , and the second plug pin extending portion 12 extends into the cavity of the plug support seat 2 .

[0040] It should be noted that, in this embodiment, the length formed by the first pin extension portion 9 and the second pin extension portion 12 is smaller than the inner diameter of the plug-in support seat 2; the length formed by the first pin plug-in portion 8 and the second pin plug-in portion 11 is greater than the inner diameter of the plug-in support seat 2, and is not greater than the outer diameter of the plug-in support seat 2.

[0041] Specifically, in actual application in pressure sensor products, a cylindrical casing is further provided on the outside of the conditioning signal circuit board 1 and the plug-in support seat 2. In order to ensure the tight connection of the components in the cylindrical casing, the outer wall of the plug-in support seat 2 matches the inner wall of the cylindrical casing.

[0042] Therefore, a constraint is imposed on the width of the signal conditioning circuit board 1 , that is, the width of the signal conditioning circuit board 1 is not greater than the outer diameter of the plug-in support seat 2 .

[0043] The structural limitation in this embodiment can ensure that the pin is clamped by the slot, and can ensure that the pin extends into the cavity of the plug support seat 2 to a sufficient depth, and can form vertical support when acting on the arc-shaped inner wall of the plug support seat 2.

[0044] As a further limitation of the present structure, the length of the first pin extension portion 9 is smaller than the length of the first pin plug-in portion 8 ; correspondingly, the length of the second pin extension portion 12 is smaller than the length of the second pin plug-in portion 11 .

[0045] In addition, the depth of the first slot 5 is greater than the depth of the second slot 6 , and correspondingly, the length of the first pin inserting portion 8 is greater than the length of the second pin inserting portion 11 .

[0046] Specifically, this structure enables the two pin-connecting parts to form a height difference clamp with the two slots, which can further ensure that the conditioning signal circuit board 1 and the plug-in support seat 2 are more stable after being vertically plugged.

[0047] In order to facilitate damage-free plugging, the present embodiment provides an arc chamfer 13 at the bottom end of the first pin extension 9 and the second pin extension 12; the arc chamfer 13 can ensure that the first pin extension 9 and the second pin extension 12 will not directly act on the first slot 5 and the second slot 6 when vertically plugged into the plug-in support seat 2, and will also be guided into the cavity of the plug-in support seat 2 by the arc chamfer 13 when partially contacting the first slot 5 or the second slot 6.

[0048] like Figure 2 and 3 As shown, the first pin plug-in portion 8 and the second pin plug-in portion 11 are respectively partially plugged with the first slot 5 and the second slot 6. In this embodiment, only the outer portions of the bottom ends of the first pin plug-in portion 8 and the second pin plug-in portion 11 are plugged with the first slot 5 or the second slot 6, and the tops of the first pin plug-in portion 8 and the second pin plug-in portion 11 are higher than the plug-in support seat 2. This structure can facilitate the electrical connection operation between the conditioning signal circuit board 1 and the functional components below.

[0049] In addition, after the first plug pin 3 and the second plug pin 4 are respectively plugged into the first slot 5 and the second slot 6, the first plug pin extension 9 and the second plug pin extension 12 will not extend out of the plug support base 2 to avoid affecting the bottom component of the plug support base 2.

[0050] It should be noted that, in this embodiment, the first pin 3, the second pin 4 and the conditioning signal circuit board 1 are integrally formed; and a clamping groove 14 is formed between the first pin 3, the second pin 4 and the bottom edge of the conditioning signal circuit board 1, and the clamping groove 14 is used to clamp the functional main board located below the conditioning signal circuit board 1 so as to achieve short-distance electrical connection.

[0051] The above description is only for illustrating the implementation mode of the present invention and is not intended to limit the present invention. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
