During the subsequent installation of electrical components on the VPX backplane, welding guns and other tools are prone to hit the VPX locating pins, which can easily cause the VPX locating pins to deform, making it difficult to accurately match them during subsequent docking, thus affecting the subsequent installation and docking of the VPX backplane.

[0003] Therefore, a VPX positioning pin protective cover is proposed. Summary of the invention

[0004] The utility model provides a VPX positioning pin protection cover, aiming to solve the problem that the existing VPX positioning pin lacks protection.

[0005] The utility model is implemented as follows: a VPX positioning pin protective cover comprises: a protective cover; a positioning pin seat arranged at one side of the protective cover; a positioning pin boss integrally formed at the central position of the outer side wall of the positioning pin seat; a positioning pin rod integrally formed at the central position of the outer side wall of the positioning pin boss; a positioning pin rod groove provided at the central position of the outer side wall of the protective cover; and a connecting cover integrally formed at the outer side wall of the protective cover near the outer side of the positioning pin rod groove; a groove provided on the inner side wall of the connecting cover; a spring embedded in the inner side wall of the groove; an elastic member provided at one end of the spring; and a convex block integrally formed on the outer side wall of the elastic member.

[0006] Preferably, the positioning pin rod and the positioning pin rod groove match and fit together, and the positioning pin rod can be embedded in the positioning pin rod groove.

[0007] Preferably, the cross section of the connecting sleeve is an annular structure, and the inner space of the connecting sleeve is connected to the positioning pin rod groove.

[0008] Preferably, there are four grooves in total, and the four grooves are symmetrically opened on the inner side wall of the connecting sleeve.

[0009] Preferably, the cross section of the protrusion is an arc-shaped structure, and the elastic member and the protrusion are integrally injection-molded.

[0010] Preferably, the inner diameter of the connecting sleeve is 1 mm larger than the outer diameter of the positioning pin boss.

[0011] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0012] By installing the protective sleeve on the outside of the positioning pin rod, the positioning pin rod can be protected to prevent welding guns and other tools from directly hitting the positioning pin rod and causing deformation. The restoring rebound force of the spring, elastic part and protrusion makes the protrusion close to the outer side wall of the positioning pin boss, ensuring that the connecting sleeve is tightly installed on the outside of the positioning pin boss, thereby preventing the protective sleeve from loosening and falling off.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0019] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a VPX positioning pin protective cover, such as Figure 1-4As shown, it includes a positioning pin seat 1, a protective sleeve 4 is provided at one side of the positioning pin seat 1, and a positioning pin boss 2 is integrally formed at the central position of the outer wall of one side of the positioning pin seat 1, a positioning pin rod 3 is integrally formed at the central position of the outer wall of one side of the positioning pin boss 2 away from the positioning pin seat 1, a positioning pin rod groove 5 is opened at the central position of the outer wall of one side of the protective sleeve 4, and a connecting sleeve 6 is integrally formed at the outer position of the outer wall of one side of the protective sleeve 4 near the positioning pin rod groove 5, and the cross section of the connecting sleeve 6 is a ring structure , and the inner space of the connecting sleeve 6 is connected to the positioning pin rod groove 5, a groove 7 is opened on the inner wall of one side of the connecting sleeve 6, and there are four grooves 7 in total, and the four grooves 7 are symmetrically opened on the inner wall of the connecting sleeve 6, a spring 8 is fixed on the inner wall of one side of the groove 7 by adhesive, and an elastic member 9 is fixed to the end of the spring 8 away from the groove 7 by adhesive, and a protrusion 10 is integrally formed on the outer wall of one side of the elastic member 9, and the cross section of the protrusion 10 is an arc structure, and the elastic member 9 and the protrusion 10 are integrally injection molded.

[0021] It should be noted that, since the existing VPX backplane is prone to collision of tools such as welding guns on the VPX locating pins during the subsequent installation of electrical components, which can easily cause the VPX locating pins to deform, making it difficult to precisely match them during subsequent docking, this embodiment protects the locating pin rod 3 by having the protective cover 4 sleeved on the outside of the locating pin rod 3, thereby preventing tools such as welding guns from directly hitting the locating pin rod 3 and causing deformation. The restoring rebound force of the spring 8, elastic member 9 and protrusion 10 allows the protrusion 10 to fit tightly against the outer wall of the locating pin boss 2, ensuring that the connecting sleeve 6 is tightly sleeved on the outside of the locating pin boss 2, thereby preventing the protective cover 4 from loosening and falling off.

[0022] Specifically, in this embodiment, this scheme mainly includes a protective sleeve 4 and a connecting sleeve 6. When protecting the locating pin rod 3, the locating pin rod groove 5 on the inner side of the protective sleeve 4 is sleeved on the locating pin rod 3, the locating pin rod 3 and the locating pin rod groove 5 fit together, and the connecting sleeve 6 is sleeved on the locating pin boss 2. When the connecting sleeve 6 moves toward the locating pin boss 2, the protrusion 10 contacts the outer wall of the locating pin boss 2, and the elastic member 9 and the protrusion 10 are deformed under pressure, and the elastic member 9 squeezes the spring 8 through the extrusion force. The spring 8 is compressed, and the elastic member 9 and the protrusion 10 are received in the groove 7. Through the reset rebound force of the spring 8, the elastic member 9 and the protrusion 10, the protrusion 10 is tightly attached to the outer wall of the locating pin boss 2, and then the connecting sleeve 6 is tightly sleeved on the outer wall of the locating pin boss 2, so as to fix the position of the protective sleeve 4, and then protect the locating pin rod 3, avoid the VPX locating pin from being damaged by external force after installation, and effectively protect the VPX locating pin.

[0023] In a further preferred embodiment of the present invention, Figure 1As shown, the positioning pin rod 3 and the positioning pin rod groove 5 match and fit together, and the positioning pin rod 3 can be embedded in the interior of the positioning pin rod groove 5.

[0024] In this embodiment, the protective cover 4 can be tightly covered on the outer side of the positioning pin rod 3, thereby protecting the positioning pin rod 3.

[0025] In a further preferred embodiment of the present invention, Figure 1 As shown, the inner diameter of the connecting sleeve 6 is 1 mm larger than the outer diameter of the positioning pin boss 2 .

[0026] In this embodiment, the connecting sleeve 6 can be sleeved on the outer side of the positioning pin boss 2 .
