Description

Technical Field

[0001] The present application relates to the technical field of injection molding jigs, and specifically discloses a wire clamping jig for injection molding of video cables. Background Art

[0002] A video cable is a coaxial cable used to transmit video signals, specifically baseband analog signals. Traditionally, a video cable consists of two aviation connectors at each end, connected to a cable with aviation plugs. The aviation plugs connect to the transmission equipment, and the cable transmits the signal.

[0003] In actual use, the connection between the aviation plug of the video cable and the cable end is mostly welding or plugging. After the cable end is placed in the aviation plug and connected to the aviation plug, there is no protection between the outer wall of the cable, the cable end and the aviation plug. It needs to be wrapped with rubber to isolate it from the external environment and extend its service life.

[0004] Typically, a layer of rubber is wrapped between the aviation plug and the outer wall of the cable end by injection molding. During the injection molding process, the aviation plug and the end of the corresponding cable to be connected need to be positioned. In the prior art, the aviation plug and cable are usually positioned only by providing grooves on the jig. However, this method is only applicable to the installation of aviation plugs and cables of one specification.

[0005] Therefore, in view of this, the inventor provides a video cable injection molding clamping fixture to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that the traditional positioning fixture used for injection molding connection of the video cable end can only adapt to the positioning of aviation plugs and cables of a single specification.

[0007] In order to achieve the above-mentioned purpose, the basic scheme of the present utility model provides a cable clamping jig for video cable injection molding, comprising a base, an aviation plug fixing seat detachably connected to one side of the base, and a cable accommodating groove provided on the base on the opposite side of the aviation plug fixing seat. The bases on both sides of the accommodating groove are provided with clamping structures for clamping the cables, the aviation plug fixing seat is provided with a fixing structure for fixing the aviation plug, and an injection molding groove is provided on the base between the aviation plug fixing seat and the accommodating groove.

[0008] Furthermore, the clamping structure includes threaded columns respectively fixed to the bases on both sides of the accommodating groove and a compression tube with internal threads and threadedly connected to the threaded columns.

[0009] Furthermore, a closed annular groove is formed on the outer edge of the bottom end of the compression tube and an inclined table is formed.

[0010] Furthermore, the base is provided with a pressing groove for the compression tube to be placed therein and which is communicated with the adjacent accommodating groove.

[0011] Furthermore, the aviation plug fixing seat includes a main board detachably connected to the base and a plug fixing piece fixed to a side of the main board facing the receiving groove and used for clamping the aviation plug.

[0012] Furthermore, the plug fixing member includes a fixing sleeve fixed to the mainboard and a fixing platform fixed in the fixing sleeve, and a jack for inserting a metal pin of the aviation plug is coaxially opened on the fixing platform.

[0013] The principle and effect of this solution are:

[0014] 1. Compared with the prior art, the present invention places the cable end into the aviation plug, places the cable into the receiving groove, and clamps the cable by adjusting the clamping structure. Then, the aviation plug is placed into the aviation plug fixing seat and fixed by the fixing structure. When applied to the injection molding of cables and aviation plugs of different sizes, the provided clamping structure and fixing structure are used to fix the cable and aviation plug respectively, solving the problem that the traditional positioning jig used for the injection molding connection of the video cable end can only adapt to the positioning of aviation plugs and cables of a single specification.

[0015] 2. Compared with the prior art, the present invention uses the threaded connection between the threaded column and the compression tube to adjust the size of the cable by twisting the compression tube, and fixes the cable through the bottom end of the compression tube.

[0016] 3. Compared with the prior art, the present invention fixes the aviation plug by placing the aviation plug into the fixing sleeve and inserting the metal pin of the aviation plug into the socket on the fixing platform. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0022] The reference numerals in the drawings of the specification include: base 1, mainboard 2, fixing sleeve 3, aviation plug 4, cable 5, compression tube 6, battery cell 7, placement groove 8, accommodating groove 9, and pressing groove 10.

[0023] A video line injection molding clamping fixture, for example Figure 1 、 Figure 2 and Figure 3 As shown:

[0024] The device comprises a base 1, a mounting base for an aviation plug 4 mounted on the left side of the base 1, and a receiving slot 9 on the right side of the base 1. In this embodiment, the base 1 has four receiving slots 9, enabling simultaneous injection molding of the connecting colloid between four pairs of aviation plugs 4 and cables 5. The base 1 also features four clamping structures for clamping the cables 5. Furthermore, the mounting base for the aviation plug 4 includes a fixing structure for each of the aviation plugs 4.

[0025] The clamping structure includes threaded posts fixedly mounted on the base 1 on either side of the receiving slot 9, and compression tubes 6 each having an internal thread and threadably connected to the threaded posts. By twisting the compression tubes 6, the distance between the bottom end of the compression tube 6 and the base 1 and the bottom end of the receiving slot 9 can be changed. By simultaneously twisting the compression tubes 6 on both sides of the receiving slot 9, the cable 5 can be compressed by having the bottom end of the compression tube 6 contact the cable 5. In this embodiment, the outer edge of the bottom end of the compression tube 6 has a closed annular groove and an inclined surface formed thereon, so that the inclined surface contacts the cable 5 and reduces wear on the cable 5. Furthermore, compression grooves 10 are coaxially formed on the end surface of the base 1 with the threaded posts. These compression grooves 10 communicate with the threaded grooves. When a cable 5 smaller than the diameter of the receiving slot 9 is placed, the compression tube 6 can be further screwed into the compression groove 10 to compress it.

[0026] The base 1 has four placement slots 8, each connected to the receiving slot 9. A clamping slot is located between the two center placement slots 8. The mounting base for the aviation plug 4 includes a mainboard 2 and four plug fixtures welded to the right side of the mainboard 2 and each inserted into the placement slot 8. A clamping base is integrally formed on the mainboard 2, which fits into the clamping slot and is secured to the base 1 with bolts.

[0027] The plug fixture consists of a fixing sleeve 3 welded to the right side of the mainboard 2 and having the same inner diameter as the mounting slot 8. A fixing platform is coaxially mounted within the fixing sleeve 3, with a gap between the outer wall of the fixing platform and the inner wall of the fixing sleeve 3. A socket is coaxially defined at the right end of the fixing platform. The metal pins of the aviation plug 4 fit into the socket, and the gap between the fixing platform and the fixing sleeve 3 accommodates the insertion of the aviation plug 4, securing it by plugging. Furthermore, a rubber pad is installed on the inner wall of the socket to accommodate metal pins of varying thicknesses. Moreover, in this embodiment, taking the 4-core interface as the GX12 aviation plug 4 as an example, the battery cells 7 of the four cables 5 are respectively placed in the interface of the aviation plug 4, and an injection molding groove is also opened on the base 1 between each accommodating groove 9 and the placement groove 8. Part of the battery cell 7 between the cable 5 and the aviation plug 4 is exposed in the injection molding groove, so that during the injection molding process, this part of the battery cell 7 can be completely wrapped, as well as the connection part of the battery cell 7 to the aviation plug 4, and the battery cell 7 and the subsequent cable 5, to achieve full coverage of the battery cell 7.

[0028] When the present invention is used, the cable 5 is placed in the accommodating groove 9, and the cable 5 is clamped by adjusting the clamping structure. Then, the aviation plug 4 is placed in the aviation plug 4 fixing seat, and the aviation plug 4 is fixed by the fixing structure. When applied to the injection molding of cables 5 and aviation plugs 4 of different sizes, the cable 5 and the aviation plug 4 can be fixed respectively by the provided clamping structure and fixing structure.

[0029] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
