Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

It should be noted that, in the present invention, terms of upper, lower, left, right, front, rear, inner, outer, front, top, bottom, and the like are defined with respect to the configurations shown in the drawings, and are relative concepts, so that they may be changed according to the positions and the use states of the present invention. These and other directional terms should not be construed as limiting terms.

Furthermore, descriptions such as those referred to as "first," "second," and the like, are provided for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying an order of magnitude of the indicated technical features in the present disclosure. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

In the present invention, unless specifically stated and limited otherwise, the terms "connected," "affixed," and the like are to be construed broadly, and for example, "affixed" may be a fixed connection, a removable connection, or an integral body; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

As known to those skilled in the art, an encoder is a portable operation device for setting codes for fire alarm devices such as a fire detector, an audible and visual alarm, a module, and an alarm button. The encoders can be classified into contact type and non-contact type according to the readout mode. An "encoder" in this context refers to a contact encoder. When encoding a product such as a fire alarm device, the encoder 10 typically uses a pair of metal clamps 12, such as alligator clamps, to clamp the signal terminals of the fire alarm devices 20a, 20b (as shown in fig. 1-2), each clamp of the pair of metal clamps being reconnected to the encoder 10 via a signal output line 11, thus enabling communicative coupling between the fire alarm devices 20a, 20b and the encoder 10. However, for different coded products, each coding operation requires one clamping operation, which is inefficient, and the frequent use of metal clamps makes them vulnerable to damage, with a short service life. Furthermore, several signal terminals of the fire alarm device may have different pitches (e.g., the pitch of a pair of signal terminals of the fire alarm device 20a in fig. 1 is greater than the pitch of a pair of signal terminals of the fire alarm device 20b in fig. 2) or have different shapes (e.g., the signal terminals of the fire alarm device may be designed as pins protruding outward, and may also be designed as sockets recessed inward), which may not facilitate the clamping connection of the metal clip, resulting in poor connection stability. Thus, there is a need for a new and versatile joint structure that facilitates quick coding.

As shown in fig. 3, which schematically illustrates the structure of one embodiment of the joint structure for an encoder of the present invention in general. The encoder according to the invention has an output line (not shown) with a clamp, which may take the form of an alligator clip. As is apparent from fig. 3-4, the joint structure 300 for an encoder is composed of a housing 310 and a pin 320. The housing 310 includes an upper surface, a lower surface, and a side surface, and the upper surface and the lower surface of the housing 310 may preferably be opposite to and parallel to each other, wherein the upper surface and the lower surface have a first through hole 311 and a second through hole, respectively, and the side surface is provided with an opening 312. The pin 320 is fixed in the housing 310, for example, by pre-burying, etc., and has an upper end portion, a middle portion, and a lower end portion, wherein the upper end portion of the pin 320 is located in the first through hole 311 and is not higher than the upper surface, so that an outwardly convex signal terminal of the encoded product (for example, a pin of the fire alarm device 200a shown in fig. 5) can be brought into contact with the upper end portion of the pin 320 through the first through hole 311, and the lower end portion of the pin 320 is extended outwardly through a second through hole of the lower surface of the housing 310 to be brought into contact with an inwardly concave signal terminal of the encoded product (for example, a socket of the fire alarm device 200b shown in fig. 6). The clamp of the encoder can be clamped to the middle portion of the pin 320 through the opening 312 of the side surface of the housing 310.

When it is desired to code a product, the head of the clamp of the encoder may be connected to and in communication with the pin 320 through the opening 312 on the side surface of the housing 310. Whether the coded product, such as the signal terminals of a fire alarm device, take the form of an outward projection or an inward recess, the joint structure 300 for an encoder according to the present invention can be adapted to: when the signal terminal of the fire alarm device takes the form of an outward bulge, such as a pin, the upper end of the pin 320 of the joint structure 300 is contacted with the signal terminal; when the signal terminal of the fire alarm device takes the form of an inward recess, such as a jack, the lower end of the pin 320 of the connector structure 300 is made to touch it. The encoding operation can be completed rapidly by merely touching the pins 320 of the header structure 300 with the contacts of the encoded product for about 2-3 seconds.

In other preferred embodiments in combination with the above embodiments, the top of the upper end of the pin 320 is provided with a first contact surface, which may be disposed parallel to the upper surface of the housing 310, and the bottom of the lower end of the pin 320 is provided with a second contact surface, which may be disposed parallel to the lower surface of the housing 310.

By way of example, the pins 320 may be configured as cylindrical bodies, for example, as cylinders, cubes, rectangular solids, or may also be configured in other geometric shapes, for example, shaped, in particular, the upper end of the pins 320 has a cross section that is not smaller than the cross section of the middle section, and the middle section has a cross section that is not smaller than the cross section of the lower end section. The invention does not strictly limit the shape, the size and the dimension of the contact pin, and can be flexibly set by a person skilled in the art according to actual requirements. It is understood that the pins 320 are made of a metal such as copper.

With continued reference to fig. 3-4, the number of pins 320 is three, and the distances between the three pins 320 are not equal. Two of the three pins 320 of the connector structure 300 may be short in pitch to form one group and two long in pitch to form another group in consideration of the difference in distance between two signal terminals of different fire alarm devices so as to be suitable for fire alarm devices having signal terminals of different pitches. Therefore, by adjusting the spacing and distribution of the contact pins, one joint can encode various fire alarm devices. For example, the spacing between the pair of signal terminals of the fire alarm device 200a shown in fig. 5 is greater than the spacing between the pair of signal terminals of the fire alarm device 200c shown in fig. 7. In the encoding process, only one pair of signal terminals of the fire alarm device 200a in fig. 5 is required to pass through the first through hole to touch the upper end of a group of pins with a longer pitch among the three pins 320, and one pair of signal terminals of the fire alarm device 200c in fig. 7 is required to pass through the first through hole to touch the upper end of a group of pins with a shorter pitch among the three pins. Further, the three pins 320 are the same size, and the axes of the three pins 320 are parallel to each other. Although the above is designed to form a joint structure for a common pin, the number of pins to which the joint structure for an encoder according to the present invention is applicable is not limited, and for example, the pins may be four. Those skilled in the art may devise joint structures that accommodate other numbers of pins in light of the teachings and/or teachings of the above embodiments.

Since the clamping members of the encoder are easily interfered with each other during clamping, the middle portions of the pins 320 may be spaced apart by a spacer 313 within the housing 310, as shown in fig. 3-4. For cost and installation reasons, the housing 310 may be an injection molded frame made of plastic.

As an example according to the present invention, in order to facilitate the operator's access to the joint structure 300, the side surface of the housing 310 is provided with symmetrical grooves 314, and a plurality of protrusions 315 are provided in the grooves 314, thereby functioning to increase friction force. This can prevent the operator from slipping off the joint structure 300 during the process of taking the joint structure 300, thereby resulting in a problem of low operation efficiency.

In addition, the invention also provides an encoder provided with the joint structure. It should be noted that the joint structure of the embodiment of the present invention may be directly applied to an encoder, for example, by connecting the output line of the belt clamping member to the encoder to form a product. The specific type of encoder and the specific structure of other components are not described in detail herein. Through button input address to main control unit, show the coding address through the display, with the help of connect structure and the fire alarm device touching of different structures carry out full-automatic coding, compare in that original output crocodile presss from both sides the operation more convenient, address transmission speed is faster, efficiency is higher when encoding on site.

In summary, the joint for the encoder has a simple structure and is convenient and quick to use, and the encoding can be realized for products with various structures in a one-time clamping and multiple-time touching mode, so that the working efficiency of operators is greatly improved. Because the clamping operation is not required to be repeated for a plurality of times, the service life of the clamping piece of the encoder is greatly prolonged.

The joint structure for an encoder of the present invention and an encoder provided with the same have been described in detail above by way of specific examples, which are given for illustration of the principle of the present invention and its embodiments, not limitation, and various modifications and improvements may be made by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, all equivalent arrangements should be considered to be within the scope of the present invention and as defined in the claims.
