Description

Technical Field

[0001] The utility model relates to the relevant technical field, in particular to a push-pull structure of a collector. Background Art

[0002] Fieldbus (commonly known as master station) is an industrial data bus that has developed rapidly in recent years. It mainly solves the digital communication between field equipment such as intelligent instruments, controllers, actuators, etc. at the industrial site, as well as the information transmission problem between these field control devices and advanced control systems.

[0003] If the signal cable moves when inserted into the IO signal collector, the signal cable and the IO signal collector may have poor contact. Even if the cable moves too far, the signal cable may become entangled with the external environment and break free, that is, the signal cable may become detached from the IO signal collector and the signal may be disconnected.

[0004] Because generally speaking, the connection between the signal line and the IO signal collector is direct plug-in, which can easily break free if pulled by external force. The direct plug-in method is certainly convenient for installation and disassembly, but it also has some disadvantages. Utility Model Content

[0005] The purpose of the utility model is to provide a push-pull structure of a collector to overcome the deficiencies in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A push-pull structure of a collector comprises a collector body, the collector body is provided with a plurality of signal connection female sockets, one end of the collector body is fixedly provided with a signal output male head, the signal connection female socket is detachably connected with a signal input male head, a slidable reverse buckle sleeve is sleeved on the outer side of the signal input male head, the signal input male head comprises a shell, a plurality of card point spring pieces are integrally extended outward from the outer side of the shell, a plurality of buckle grooves are opened on the side wall of the reverse buckle sleeve, and the buckle grooves are sleeved on the card point spring pieces.

[0008] To further explain, a plurality of card point spring pieces are arranged in a circular array on the outside of the shell, and a circular array of buckle grooves are arranged on the outer peripheral side of the reverse buckle sleeve.

[0009] To further explain, the clamping point spring piece is arranged on the side wall close to the end of the shell, and an umbrella-shaped arc surface inclined from the inside to the outside is provided on the side of the clamping point spring piece facing the end of the shell.

[0010] To further explain, the shell and the reverse buckle sleeve are both provided with an edge protrusion protruding toward the outer peripheral side, the buckle grooves and the card point spring pieces are both arranged at the edge protrusions, and the number and positions of the buckle grooves correspond to the card point spring pieces.

[0011] To further explain, the signal connection socket is provided with a jack, and the side wall of the jack is provided with a plurality of limiting side holes extending outward, the limiting side holes are arranged in a ring array around the jack, and the side wall of the limiting side hole also extends outward to form a snap groove for snapping with the card point spring clip.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model is provided with a reverse buckle sleeve that can move forward and backward at the male connector at the end of the signal line. During the plugging process, the reverse buckle sleeve is first pulled back to a certain position, and when the clamping point spring piece sinks, it can be inserted, and the clamping point spring piece of the reverse buckle sleeve is released and re-clamped on the connection female socket to complete the connection. The signal line is not easy to be pulled out under the action of external force, and the reverse buckle sleeve needs to be slid to be pulled out. This effectively prevents the signal line from being pulled out by mistake, standardizes the action of signal line plugging, and avoids the possibility of signal disconnection.

[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. When the number of an element is referred to as "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific implementations and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] The present invention is described in detail below in conjunction with the embodiments shown in the accompanying drawings:

[0024] like Figure 1-4 As shown, in this embodiment, a push-pull structure of a collector is provided, including a collector body 1, the collector body 1 is provided with a plurality of signal connection female sockets 2, one end of the collector body 1 is fixedly provided with a signal output male connector, the collector collects the input signal through the signal connection female socket 2 and then outputs the collected and processed signal data again through the signal output male connector.

[0025] The signal connection female socket 2 is detachably connected with a signal input male plug 8, and a slidable reverse buckle sleeve 7 is sleeved on the outside of the signal input male plug 8. The main reason why the signal input male plug 8 can be prevented from coming out is because of the reverse buckle sleeve 7. The signal input male plug 8 includes a shell, and a plurality of card point spring pieces 6 are integrally extended outward from the outside of the shell, and a plurality of buckle grooves 9 are provided on the side wall of the reverse buckle sleeve 7, and the buckle grooves 9 are sleeved on the card point spring pieces 6. The card point spring pieces 6 are preferably made of elastic material extending outward, and the card point spring pieces 6 are used to buckle on the signal connection female socket 2. Under normal circumstances, they are ejected outward. When the signal input male plug 8 needs to be plugged into the signal connection female socket 2, the card point spring piece 6 needs to be pressed inward (toward the axis center of the cable), and the card point spring piece 6 leaves the buckle connection with the signal connection female socket 2. At this time, the signal input male plug 8 can be freely plugged or pulled out of the signal connection female socket 2.

[0026] The control of the retraction and ejection of the card point spring piece 6 (the direction of movement of the card point spring piece 6 is radial) is due to the sliding of the reverse buckle sleeve 7 on the signal input male head 8, and the corresponding action occurs. The card point spring piece 6 penetrates the reverse buckle sleeve 7 through the buckle groove 9. When the reverse buckle sleeve 7 is controlled to move in the opposite direction away from the signal input male head 8, the reverse buckle sleeve 7 can retract and press the card point spring piece 6 inward through the buckle groove 9. The above-mentioned retraction refers to the deformation of the card point spring piece 6 so that it is no longer engaged with the buckle groove 3 (mentioned below).

[0027] In this embodiment, a plurality of card point spring pieces 6 are arranged in a circular array on the outside of the shell, and the snap-on grooves 9 are arranged in a circular array on the outer peripheral side of the reverse buckle sleeve 7. The card point spring piece 6 is arranged on the side wall close to the end of the shell, and the side of the card point spring piece 6 facing the end of the shell is provided with an umbrella-shaped arc surface inclined from the inside to the outside. That is to say, the card point spring piece 6 is an approximate triangle with an arc-shaped extension in cross section. When the reverse buckle sleeve 7 is pulled up and slid, the card point spring piece 6 can be pressed inward by this arc-shaped extension. When the signal input male plug 8 is pulled out, it is necessary to pull up the reverse buckle sleeve 7 to restrict the card point spring piece 6 from popping out.

[0028] Under normal conditions, the card point spring piece 6 is ejected normally and passes through the buckle sleeve 7 through the buckle groove 9 mentioned above.

[0029] In this embodiment, in order to prevent the signal input male plug 8 from rotating after being inserted and connected, it is preferred that an extension protrusion 4 protruding toward the outer peripheral side is provided on the shell and the reverse lock sleeve 7, and the snap-on grooves 9 and the card point spring pieces 6 are arranged on the extension protrusion 4, and the number and positions of the snap-on grooves 9 correspond to the card point spring pieces 6.

[0030] At the same time, a socket is provided on the signal connection socket 2, and a plurality of limiting side holes 5 extending outward are provided on the side wall of the socket. The limiting side holes 5 are arranged in a circular array around the socket, and a buckle groove 3 for buckling with the clamping point spring 6 is extended outward from the side wall of the hole of the limiting side hole 5. The limiting side hole 5 corresponds to the edge protrusion 4.

[0031] During the insertion process, the card point spring piece 6 abuts against the side wall of the limiting side hole 5. At this time, the card point spring piece 6 is deformed inwardly under the restriction of the side wall of the limiting side hole 5. After being inserted into place, the card point spring piece 6 restores its shape and re-engages on the buckle groove 3 to complete the limiting engagement.

[0032] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. For ordinary technicians in this field, they can make several modifications and improvements without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
