Description

  The present invention relates to an anti-theft device for signal connectors, and in particular, various shapes and angles by engaging a driven part of a hand tool with an operating part of a screw fixing member housed in a fitting body and a through hole of a rotating body. Further, the present invention relates to an antitheft device for a signal connector that has a specific property and increases the tightening tightness when the signal connector is rotated to perform an antitheft function.

  Cable TV (CATV), which is the prototype of the cable television system used in the current community, is a coaxial cable that connects RF signals through optical fiber networks, optical node conversion, etc., and a signal distributor as a transmission medium. It provides various services such as radio TV, digital TV, request, and high-speed Internet for each user in the community.

  In addition, most of the optical fiber networks installed by system agents are either coaxially laying coaxial cables on utility poles, or laying on the outer walls of buildings, and signal distributors at the end of coaxial cables using nuts. Used by screwing on the upper joint. In order to effectively prevent community customers from connecting to cable TV without permission, a common practice is to screw the closure joint over the other unused coupling joints of the signal distributor, and then use the closure joint. Is used to block the connection between the coaxial cable and the coupling joint on the signal distributor, and in order to achieve a tight screwing and anti-theft function, a special tool is required when sealing the closing joint and the coupling joint together. Necessary.

  11 and 12 are a three-dimensional exploded view and a sectional view of a known signal connector anti-theft structure. Among them, the anti-theft connector A includes a hollow cylindrical outer fitting portion A1, and a cylindrical inner fitting portion A2 housed inside the cylindrical outer fitting portion A1 is provided with a threaded portion A21. In addition, a coupling slot A22 having a plurality of annular teeth A221 is formed at one side away from the threaded portion A21, and a protruding cone-shaped portion A222 is formed at the bottom of the coupling slot A22. When the rod B1 of the hand tool B is inserted into the cylindrical outer fitting portion A1, the rotary pusher B21 pivotally attached to the driven portion B2 on one side of the rod B1 is a conical shape at the bottom of the coupling slot A22. The portion A222 is supported in the axial direction, and the rotary push body B21 is rotated at an angle along the inclined surface of the conical portion A222, and is further fitted and supported in the radial direction on the annular tooth A221 of the coupling slot A22. Driven by B, the screwed portion A21 of the cylindrical inner fitting portion A2 and the joint portion C1 on the signal connector C are screwed together to be integrated.

  However, the rotary push body B21 of the hand tool B is fitted and supported on the annular tooth A221 located in the coupling slot A22 of the antitheft connector A, and the main body size and angle of the rotary push body B21 are very accurate. The cylindrical inner fitting portion A2 can be smoothly rotated. Otherwise, the portion to which the rotary push body B21 applies a force is easily worn, and a surface wear phenomenon occurs in the annular tooth A221 of the cylindrical inner fitting portion A2. In addition, due to the insufficient push force of the single rotary push body B21, a greater torsional force is applied, or if the angle is not correct, the screwing becomes hard and damage such as lack of the annular tooth A221 occurs. The rotary push body B21 closes the inside of the coupling slot A22 of the cylindrical inner fitting portion A2, thereby causing a catch or functional invalidity. Further, the anti-theft connector A is already widely used in the market, and the anti-theft connector A can be released by simply using the commonly used hand tool B. The effectiveness of the function is lost, and the anti-theft connector A is lacking in uniqueness and expertise because of the few types that can be selected, and the universality of the hand tool B is also used according to the wide distribution in the market. Due to the increase, the anti-theft function of the anti-theft connector A is lost, and therefore there is a direction of research improvement in the industry here.

The stopper 212 at the edge around the opening 101 of the fitting body 1 is pressed and supported by the support portion 212 to be positioned, and the rotating body 3 is positioned between the screwing fixing member 2 and the fitting body 1. When the column 32 is inserted into the passage 11 of the fitting body 1, the screw fixing member 2 and the rotating body 3 are prevented from falling out of the fitting body 1, and the screw fixing member 2 and the rotating body 3 are stored in the storage space of the fitting body 1. 10 can be rotated, thus completing the assembly of the present invention.

  5 to 8 show a side sectional view before use of the present invention, a side sectional view during use, a side sectional view after use, and a three-dimensional perspective external view of a preferred embodiment. As can be understood from the figure, the signal connector anti-theft device of the present invention is applied to the signal distributor, adapter, or other electronic device 6 in the electrical equipment of the cable television system, and the user can grasp the grip portion 43 of the hand tool 4. , The driven portion 42 on one side of the rod body 41 is inserted into the storage space 10 from the passage 11 of the fitting body 1, and a plurality of transition bodies 421 protruding from the peripheral edge of the driven portion 42 are provided on the rotating disk of the rotating body 3. It is inserted into a plurality of through holes 31 located at 30. If the plurality of through holes 31 of the rotating body 3 and the plurality of actuating portions 22 of the screw fixing member 2 are in a shifted position, the fitting of the actuating portion 22 with the plurality of transition bodies 421 around the driven portion 42 of the hand tool 4 is performed. Even if the outer surface of the landing groove 221 is pressed, it cannot enter forward. In this state, the grip portion 43 is turned to rotate the driven rod body 41 clockwise or counterclockwise so that the plurality of transition bodies 421 of the driven portion 42 and the fitting grooves 221 of the operating portion 22 face each other and are fitted. When inserted into the groove 221, a fitting state in a movable state is formed, and the notch 422 formed between the plurality of transition bodies 421 supports the rotating body 3, so that the rod body 41 is stored in the storage space 10. Limit the distance to insert in. As a result, when the driven portion 42 on one side of the bar 41 of the hand tool 4 fits the rotating body 3, the screw fixing member 2 also rotates simultaneously with this, so that the screw fixing member 2 and the electronic device 6 are also rotated. The screwing work of the upper signal connector 5 is made convenient.

  Furthermore, when the rod body 41 of the hand tool 4 is inserted into the storage space 10 from the passage 11 of the fitting body 1, the localization column 32 at the center of the rotating disk 30 of the rotating body 3 extends into the passage 11, and the rod body Since the fitting hole 420 for inserting the stereotaxic column 32 is formed at the central portion of the driven portion 42 of 41, the hand tool 4 can be continuously pushed forward, and the first antitheft mechanism It becomes.

In addition, the cross section of the transition body 421 is rectangular, arc-shaped, circular, elliptical, or polygonal, and the included angles formed by both sides of the transition body 421 are 120 degrees, 155 degrees, 165 degrees, and 195. Designed with degrees, 205 degrees, or other various α angles. The design for engaging the transition body 421 of the hand tool 4 customized according to market demands with the fitting groove 221 of the screwing fixing member 2 and the structure of the through hole 31 of the rotating body 3 has various shapes and angles. It can be varied and has a unique and customized personality. For example, the key system has a variety and selectivity that can be changed to different forms as a whole, and can prevent illegal connection using a common hand tool 4 in the general market. Screwing and anti-theft function can be enhanced.

  The follower 42 on one side of the hand tool 4 of the present invention includes at least two transition bodies 421, and the size and angle of the fitting groove 221 of the screwing fixing member 2 to be engaged and the through hole 31 of the rotating body 3. May not be very accurate. Further, the hand tool 4 rotates the screw fixing member 2 by passing the driven portion 42 on one side of the rod body 41 through the rotating body 3, and the entire structure is very simple, the structural strength is good, and the thread groove Damage due to crushing or broken threads can be avoided. Therefore, the tight screwing and anti-theft function of the connection space 20 of the screw fixing member 2 and the joint portion 51 of the signal connector 5 can be reliably realized.
