Description

Technical Field

[0001] This utility model relates to the technical field of cable accessory connection devices, specifically a cable accessory connection device. Background Technology

[0002] Cable accessories are a collective term for the components and materials used to install or make various cable joints and terminations in cable lines. They are an essential part of cable lines. During the cable installation and laying process, cable connection accessories need to be connected to the cable.

[0003] Traditional cable accessory connection devices typically involve directly attaching the cable accessory to the top of the cable and using special tools to clamp it, causing deformation. This deformation then connects the cable accessory to the cable. However, relying solely on the deformation of the cable accessory to connect them is problematic. If the cable is pulled during use, the cable accessory may detach from the cable, affecting its normal operation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cable accessory connection device that has the advantages of good connection stability and ease of use, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a connecting device for cable accessories, including a cable body, a connecting accessory installed on the top of the cable body, a contact rod fixedly assembled in the inner cavity of the connecting accessory, a fixing plate installed on the outer wall of the connecting accessory, a clamping plate rotatably connected to the outer wall of the fixing plate, a fixing rod fixedly assembled on the outer wall of the clamping plate, a rotating rod rotatably connected to the outer wall of the fixing rod, an adjusting nut threadedly connected to the outer wall of the rotating rod, a pressure plate movably sleeved on the outer wall of the rotating rod, a driving spring movably sleeved on the outer wall of the rotating rod, an auxiliary plate fixedly assembled on the outer wall of the clamping plate, a pressure plate fixedly assembled on the outer wall of the auxiliary plate, a sealing sleeve movably sleeved on the outer wall of the cable body, and an installation groove formed on the outer wall of the fixing plate.

[0006] As a preferred technical solution of this utility model: the outer wall diameter of the fixing plate and the clamping plate matches the outer wall diameter of the connecting accessory, and the bottom of the contact rod contacts the top of the cable body.

[0007] As a preferred technical solution of this utility model: the two ends of the outer wall of the drive spring are in contact with the outer wall of the adjusting nut and the outer wall of the pressure plate, respectively, and the drive spring is made of high carbon steel.

[0008] As a preferred technical solution of this utility model: there are two rotating rods, and the two rotating rods are respectively rotatably connected to both ends of the outer wall of the clamping plate.

[0009] As a preferred technical solution of this utility model: the outer diameter of the rotating rod is matched with the distance between the inner wall of the mounting groove, and the outer shape of the pressure plate is matched with the outer shape of the sealing sleeve.

[0010] As a preferred technical solution of this utility model: auxiliary plates are installed on the outer walls of both the fixing plate and the clamping plate, and the sealing sleeve is made of natural rubber.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The connecting device of this cable accessory uses a fixing plate and a clamping plate set on the outer wall of the connecting accessory. Under the action of the adjusting nut, the drive spring is compressed, so that the pressure plate is attached to the outer wall of the fixing plate. This brings the fixing plate and the clamping plate closer to each other, thereby applying pressure between the connecting accessory and the cable, thus realizing the connection between the connecting accessory and the cable body. This avoids the traditional equipment that achieves fixation through the deformation of the connecting accessory, and improves the stability of the connection.

[0012] 2. The connecting device of this cable accessory, through the setting of the sealing sleeve, achieves a sealing effect between the cable body and the cable connecting accessory under the action of the sealing sleeve. When the fixing plate and the clamping plate approach each other, the pressure plate applies pressure to the sealing sleeve, thereby making the sealing sleeve better seal between the cable body and the connecting accessory.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 6 A cable accessory connection device includes a cable body 1, a connection accessory 2 installed on the top of the cable body 1, a contact rod 3 fixedly assembled in the inner cavity of the connection accessory 2, a fixing plate 4 installed on the outer wall of the connection accessory 2, a clamping plate 5 rotatably connected to the outer wall of the fixing plate 4, a fixing rod 6 fixedly assembled on the outer wall of the clamping plate 5, a rotating rod 7 rotatably connected to the outer wall of the fixing rod 6, an adjusting nut 8 threadedly connected to the outer wall of the rotating rod 7, a pressure plate 9 movably sleeved on the outer wall of the rotating rod 7, a drive spring 10 movably sleeved on the outer wall of the rotating rod 7, an auxiliary plate 11 fixedly assembled on the outer wall of the clamping plate 5, a pressure plate 12 fixedly assembled on the outer wall of the auxiliary plate 11, a sealing sleeve 13 movably sleeved on the outer wall of the cable body 1, and an installation groove 14 formed on the outer wall of the fixing plate 4. In the above structure, by rotating the adjusting nut 8, the drive spring 10 is compressed, thereby driving the pressure plate 9, so that the pressure plate 9 fits against the outer wall of the fixing plate 4, thereby achieving a pre-tightening effect between the fixing plate 4 and the clamping plate 5. At this time, the connecting accessory 2 and the cable body 1 can be clamped together under the action of the fixing plate 4 and the clamping plate 5, thus completing the installation of the connecting accessory 2.

[0017] In a preferred embodiment: the outer diameter of the fixing plate 4 and the clamping plate 5 matches the outer diameter of the connecting accessory 2, and the bottom of the contact rod 3 contacts the top of the cable body 1; In the above structure, the contact rod 3 provided in the inner cavity of the connecting accessory 2, when connecting the connecting accessory 2 and the cable body 1 under the action of the fixing plate 4 and the clamping plate 5, can connect the contact rod 3 in the inner cavity of the connecting accessory 2 to the top of the cable body 1, thereby achieving the conductive effect of the cable body 1 under the action of the connecting accessory 2, and thus realizing the connection between the connecting accessory 2 and the cable body 1.

[0018] In a preferred embodiment: the two ends of the outer wall of the drive spring 10 are in contact with the outer wall of the adjusting nut 8 and the outer wall of the pressure plate 9, respectively, and the drive spring 10 is made of high carbon steel; In the above structure, the drive spring 10 provided on the outer wall of the rotating rod 7 can be compressed by the adjusting nut 8 when the adjusting nut 8 is rotated. This causes the pressure plate 9 to move under the action of the drive spring 10, so that the pressure plate 9 fits against the outer wall of the fixed plate 4. This prevents the rotating rod 7 from disengaging from the inner cavity of the mounting groove 14, and makes the fixed plate 4 and the clamping plate 5 fit tightly against each other, thus clamping and fixing the connecting accessory 2 and the cable body 1.

[0019] In a preferred embodiment, there are two rotating rods 7, and the two rotating rods 7 are respectively rotatably connected to both ends of the outer wall of the clamping plate 5; In the above structure, by setting two rotating rods 7 on the outer wall of the clamping plate 5, and by setting adjusting nuts 8 and driving springs 10 on the outer walls of the two rotating rods 7, the pressure plate 9 can be stably attached to the outer wall of the fixing plate 4, thereby better achieving the fixing effect of the fixing plate 4 and the clamping plate 5, and ensuring that the fixing plate 4 and the clamping plate 5 stably clamp and fix the cable body 1 and the connecting accessory 2.

[0020] In a preferred embodiment: the outer diameter of the rotating rod 7 matches the distance between the inner wall of the mounting groove 14, and the outer shape of the pressure plate 12 matches the outer shape of the sealing sleeve 13; In the above structure, by providing auxiliary plates 11 and pressure plates 12 on the outer walls of the fixing plate 4 and the clamping plate 5, when the fixing plate 4 and the clamping plate 5 are close to each other, pressure can be applied to the sealing sleeve 13 under the action of the auxiliary plates 11 and pressure plates 12, so that the sealing sleeve 13 fits more tightly with the cable body 1 and the connecting accessory 2, thereby achieving a better sealing effect under the action of the sealing sleeve 13.

[0021] In a preferred embodiment: auxiliary plates 11 are installed on the outer walls of both the fixing plate 4 and the clamping plate 5, and the sealing sleeve 13 is made of natural rubber; In the above structure, the sealing sleeve 13 provided on the outer wall of the cable body 1 is located at the connection between the cable body 1 and the connecting accessory 2 when the sealing sleeve 13 is fitted onto the outer wall of the cable body 1. Then, pressure is applied to the sealing sleeve 13 under the action of the fixing plate 4 and the clamping plate 5, so that the sealing sleeve 13 is stably installed at the connection between the cable body 1 and the connecting accessory 2, thereby sealing the connection between the cable body 1 and the connecting accessory 2.

[0022] Working principle: During the use of the above equipment, when it is necessary to connect the cable body 1 and the connecting accessory 2, the connecting accessory 2 is sleeved on the top of the cable body 1, the sealing sleeve 13 is installed at the connection between the cable body 1 and the connecting accessory 2, and the fixing plate 4 and the clamping plate 5 are respectively installed on the outer wall of the connecting accessory 2. Then, the rotating rod 7 is rotated so that the rotating rod 7 enters the inner cavity of the mounting groove 14, and the adjusting nut 8 is rotated. Under the action of the adjusting nut 8, the drive spring 10 is driven. Since the outer wall of the drive spring 10 is in contact with the outer wall of the pressure plate 9, the adjusting nut 8 and the drive spring 10 are engaged. Under the action of the pressure plate 9, the pressure plate 9 is stably attached to the outer wall of the fixing plate 4, thereby achieving the connection effect between the fixing plate 4 and the clamping plate 5. At this time, the connection effect between the cable body 1 and the connecting accessory 2 can be achieved under the action of the fixing plate 4 and the clamping plate 5. As the fixing plate 4 and the clamping plate 5 approach each other, they will push the auxiliary plate 11 and the pressure plate 12 to move, thereby causing the pressure plate 12 to apply pressure to the sealing sleeve 13, so that the sealing sleeve 13 can play a good sealing effect at the connection between the cable body 1 and the connecting accessory 2, ensuring the stability of the connection between the cable body 1 and the connecting accessory 2.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
