Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electronic connector, in particular to a plug -in guide. BACKGROUND

[0002] Grounding tabs play a crucial role in plug-in guides. They are mainly used to ensure the safe grounding of equipment to prevent potential hazards such as electrical leakage, static accumulation, and lightning strikes. Grounding tabs are usually fixed to the metal shell of the device or dedicated grounding points through fasteners such as screws to establish a stable electrical connection.

[0003] However, the existing grounding tab design has the risk of falling in some cases, which may be caused by the gap fit between the grounding tab and the mounting slot. Once the grounding tab falls off, it will directly lead to the loss of effective grounding protection of the electrical system, which may cause a series of safety problems.

[0004] Among them, the most serious is the risk of power short circuit fire. After the grounding tab falls off, the current that should be guided away through the grounding path may find other paths, such as through the insulation layer of the device, adjacent wires or components, etc. These unexpected current paths often have lower resistance, so the current will increase rapidly, generating a large amount of heat, which may cause the burning of insulating materials if the heat cannot be dissipated in time, and may further lead to the occurrence of fire.

[0037] Referring to Figures 1 to 8 The utility model embodiment provides a kind of plug-in guide, comprising: base 1, grounding spring 2, guide pin 3;

[0038] Wherein, base 1 is used to support and fixed component, bearing the installation and positioning of grounding spring 2, guide pin 3;Grounding spring 2 is used to guide through in the sliding process of guide pin 3;Guide pin 3 is used to connect printed circuit board PCB, and in the sliding process with grounding spring 2 abuts, realizes guide through;

[0039] Specifically, grounding spring 2 includes spring hook 201, fixed part 202, guide end solder leg 203, the spring hook 201 one end is sequentially provided fixed part 202, guide end solder leg 203;The spring hook 201 is set in the mounting groove 101 on base 1, and the fixed part 202 is interference fit with mounting groove 101;

[0040] Guide pin 3 is slidably arranged in the mounting hole 102 on base 1, and in the sliding process along mounting hole 102 with the other end of spring hook 201 abuts.

[0041] In the utility model, the fixed part 202 of grounding spring 2 is interference fit with mounting groove 101, to ensure the stable installation of grounding spring 2, to avoid guide pin 3 in the sliding process causes grounding spring 2 to fall, improve the security of plug-in guide.

[0042] Specifically, mounting groove 101 includes first section groove 1011, second section groove 1012, third section groove 1013, the first section groove 1011, second section groove 1012, third section groove 1013 are sequentially arranged along the first direction of base 1.

[0043] Exemplarily, the first direction is the axial direction of base 1, i.e. X direction, the second direction is along the transverse direction perpendicular to the radial direction, i.e. Y direction, the third direction is along the longitudinal direction perpendicular to the radial direction, i.e. Z direction.

[0044] Further, the first section of the groove 1011 is used to accommodate the spring hook 201, the second section of the groove 1012 is in interference fit with the fixed part 202, and the third section of the groove 1013 is in sliding fit with the guide end soldering leg 203. In this way, when the grounding spring 2 is installed into the installation groove 101, the guide end soldering leg 203 of the grounding spring 2 is guided to slide in the third section of the groove 1013, thereby playing a guiding role; the fixed part 202 is in interference fit in the second section of the groove 1012, that is, a fixed connection is achieved; when the guide pin 3 reciprocates along the first direction, the entire grounding spring 2 cannot fall off due to the interference of the fixed part 202 with the two sides of the second section of the groove 1012, thereby ensuring safety and reliability during use.

[0045] Exemplarily, the second section of the groove 1012 and the third section of the groove 1013 have a stepped cross section in the installation groove 101.

[0046] In the embodiment, the fixed part 202 can have a sharp corner structure on both sides along the second direction, and the sharp corner structure faces the guide end soldering leg 203. In this way, the sharp corner structure is more stable in clamping with the second section of the groove 1012.

[0047] In the embodiment, the guide end soldering leg 203 extends along the second direction to a length greater than that of the fixed part 202, that is, the width of the guide end soldering leg 203 is greater than that of the fixed part 202. In this way, on the one hand, the space between the grounding spring 2 and other elements can be ensured to be sufficient, thereby avoiding potential interference or conflict; on the other hand, the contact area can be increased, which is helpful for more effectively discharging static electricity from the protected elements to the ground or other safe positions.

[0048] Further, the spring hook 201 is upwardly curved along the third direction and forms an included angle with the first direction.

[0049] Exemplarily, the spring hook 201 is upwardly curved along the third direction by 12°, so that a part of the spring hook 201 is located outside the installation groove 101 and in the installation hole 102. In this way, when the guide pin 3 is inserted into the installation groove 101, the head of the guide pin 3 contacts the curved part of the spring hook 201.

[0050] Further, the fixed end surface of the base 1 is also provided with at least two installation columns 103 along the first direction. In this way, when the base 1 is installed, the installation columns 103 can help to ensure that the base 1 and other components are correctly aligned and positioned, and can also ensure that the base 1 is stable and cannot move after installation, thereby preventing the base 1 from moving due to the insertion and extraction of the guide pin 3.

[0051] In the embodiment, the fixed end surface is the bottom surface of the base 1.

[0052] Further, the end face of the base 1 close to the guide pin 3 is a plane, so as to reduce the machining process, save materials, and reduce the complexity of processing.

[0053] Further, the end face of the guide pin 3 is further provided with a boss 301 for increasing the contact area, so that the contact area of the guide pin 3 is increased, the strength and stability of the connection are increased, the risk of PCB board failure caused by poor connection is reduced, and the connection point can still maintain stability and reliability with the PCB board during long-time operation, thereby avoiding the risk of damage to the PCB board caused by small contact area and large force in the related art.

[0054] Further, the outer side of the base 1 is further provided with a guide installation groove 104 along the first direction, which cooperates with the installation column 103, and helps to ensure that the base 1 and other components are correctly aligned and positioned.

[0055] Further, the length of the head 302 of the guide pin 3 is greater than the length of the installation groove 101, so that when the guide pin 3 is inserted into the installation groove 101, the head of the guide pin 3 contacts the other end of the grounding spring 2 due to the increased length of the head 302 of the guide pin 3, and the prior guidance is achieved.

[0056] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and replacements made by those skilled in the art on the basis of the present application are within the scope of protection of the present application.
