Description
Technical Field
The utility model relates to an electron field especially relates to an anti-drop PIN needle.
Background
Currently, PIN is a metallic substance used in connectors to accomplish electrical conduction. The PIN needle belongs to a high-precision product, and the tolerance requirement is +/-0.001- +/-0.0005. In the operation of producing the ceramic ferrule by ceramic powder injection molding, a core pin is required to be resistant to a series of high-requirement environments such as acid, corrosion and high temperature, and the core pin is completely qualified for the operation in the high-temperature corrosion environment for industrial teeth such as hard alloy. The hard alloy core needle is suitable for the high-temperature working environment in the process of producing the nano zirconia by the ceramic powder injection molding die, and the long-acting lasting operation enables the large-scale and batch production operation of the ceramic ferrule to become the most direct embodiment.
However, the existing PIN has the following defects:
PIN needles on the market are easy to separate in the using process, and influence is caused on the quality of products.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, one of the purposes of the utility model is to provide an anti-drop PIN needle, which can solve the problem of easy separation.
The utility model discloses an one of the purpose adopts following technical scheme to realize:
the utility model provides an anti-drop PIN needle, includes middle part connecting rod and conflict portion, the middle part connecting rod is cylindricly, conflict portion fixed connection in the middle part connecting rod, conflict portion lower part is equipped with the depressed part, conflict portion forms first plane of projection, second plane of projection and third plane of projection along the vertical direction projection, first plane of projection is on a parallel with the middle part connecting rod, first plane of projection with the obtuse angle is personally submitted in the second projection, the second plane of projection with the acute angle is personally submitted in the third projection, epoxy rubber coating cladding in conflict portion.
Further, the first projection plane and the second projection plane are 120-150 degrees.
Further, the first projection plane and the second projection plane are 125 degrees.
Further, the number of the collision parts is 1-4.
Further, the number of the collision parts is 2.
Compared with the prior art, the beneficial effects of the utility model reside in that:
the first projection surface and the second projection surface form an obtuse angle, the second projection surface and the third projection surface form an acute angle, and the epoxy encapsulation covers the contact part. Through conflict portion prevents to deviate from in epoxy rubber coating, just the depressed part makes the area increase that conflict portion is absorbed in epoxy rubber coating, and the cladding effect is better.
The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention may be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are described in detail with reference to the accompanying drawings.
Drawings
Fig. 1 is a structural diagram of a preferred embodiment of the anti-falling PIN of the present invention;
FIG. 2 is a top view of an interference portion of the anti-drop PIN of FIG. 1;
FIG. 3 is a side view of the interference part shown in FIG. 2;

In the figure: 100. an anti-drop PIN needle; 10. a middle connecting rod; 20. a contact part; 21. a recessed portion; 22. a middle through hole; 201. a first projection plane; 202. a second projection plane; 203. and a third projection plane.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 to 4, an anti-drop PIN 100 includes a middle connecting rod 10 and an abutting portion 20, the middle connecting rod 10 is cylindrical, the abutting portion 20 is fixedly connected to the middle connecting rod 10, a recessed portion 21 is disposed at a lower portion of the abutting portion 20, the abutting portion 20 forms a first projection plane 201, a second projection plane 202 and a third projection plane 203 along a vertical direction, the first projection plane 201 is parallel to the middle connecting rod 10, the first projection plane 201 and the second projection plane 202 form an obtuse angle, the second projection plane 202 and the third projection plane 203 form an acute angle, and epoxy is encapsulated in the abutting portion 20.
