Description
- This continuing application claims priority to U.S. patent application Ser. No. 13/041,257 filed Mar. 04, 2011 which divisional application claims priority to U.S. patent application Ser. No. 11/900,124 filed Sep. 10, 2007 and issued on Mar. 22, 2011 as U.S. Pat. No. 7,908,741 with the United States Patent and Trademark Office.
- This invention relates generally to installing a connector onto a coaxial cable, and specifically to a hydraulic compression tool for securing a prepared end of a coaxial cable in operative engagement with a cable connector.
- A wide variety of compression type end connectors have recently been developed for use in the cable industry. These devices have found wide acceptance because of ease of manufacture and lack of complexity in design and in use. For example, the compression type connector for use with braided coaxial cables can include a hollow body and a hollow post mounted within the body which passes through one end wall of the body, and a threaded nut that is rotatably mounted on the extended end of the post. A compression member can be mounted on the connector body and arranged to move axially into the back end of the body. One end of a coaxial cable can be prepared by stripping the back outer portions of the cable to expose the center connector. The coaxial cable can then be passed through the compression ring into the back end of the body allowing the hollow post to pass between the woven metal mesh layer of the cable and the inner dielectric layer so that the wire mesh layer and outer barrier layer are positioned in the body cavity between the post and the inner wall of the body. Installation of the connector upon the end of the prepared coaxial cable is completed by axial movement of the compression member over an inclined surface to produce a radial deformation of the compression member into operative engagement with the outer surface of the coaxial cable thus securing the connector to the end of the cable. Connectors for use with other types of cables (e.g., corrugated cables, smooth wall cables) can also include a compression member which needs to be compressed to achieve an operative engagement of the cable with the cable connector.
- Although most of the compression type end connectors work well in securing the coaxial cable to the end connector, the installer oftentimes has difficulty in applying a high enough axially directed force to effectively close the connection. A force that is applied off axis will not properly deform the compression member, thus resulting in a less than successful closure between the connector and the cable. Thus, a need exists for a compression tool for installing a coaxial cable connector onto a coaxial cable which is suitable for using with different connector types and cable sizes.
- It is a primary object of the present invention to provide a hydraulic compression tool for securing a compression type end connector to a prepared end of a coaxial cable.
- It is a further object of the present invention to provide a hydraulic compression tool which is suitable for using with different connector types and cable sizes.
- These and other objects of the present invention are attained by a hydraulic compression tool including a hydraulic assembly having an axially extendable ram, and a connector frame detachably attached to the hydraulic assembly. The connector frame can include a cable cradle configured to accommodate cables of various sizes, a sliding guide structure mounted to the cable cradle, and a sleeve for engaging a cable connector. The sliding guide structure can include a sliding bar and one or more sliding guides. The sleeve can be attached to the sliding bar. The sleeve can be configured to accommodate connectors of various sizes. Activating the hydraulic assembly can cause the ram to extend, which in turn can cause the sliding bar to move along the longitudinal axis of the cable connector compressing the compression member and connector body into operative engagement of the cable with the cable connector.

Thesleeve 520 can be attached to aextendable ram 57 by a bolt 521.Ram 57 can be received through anopening 531 in theframe 530. - In one aspect, the
frame 530 can have internal threads at one end. The mountingcylinder 56 of thehydraulic compression assembly 512 can have an outer surface, at least aportion 56 a of which can have external threads. Theframe 530 can be threadably attachable to the externally threaded portion of the mountingcylinder 56. -
FIGS. 6 a and 6 b illustrate a cable connector before and after having being compressed by the hydraulic compression tool according to the embodiment ofFIGS. 5 a-5 c. Thecable connector 60 is placed into theconnector frame assembly 54 so that the deformable section of the cable connector is received by thecable cradle 514, and theconnector body 67 of the cable connector is received by thesleeve 520. A prepared end of coaxial cable (not shown) is inserted into the deformable section of the cable connector. The operator of the hydraulic compression tool activates thehydraulic assembly 512, so that theextendable ram 57 of thehydraulic assembly 512 extends, which results in thecompression member 68 andconnector body 66 being compressed along thelongitudinal axis 500 of the cable connector, causing the coaxial cable being secured in operative engagement to the cable connector.
Claims (10)
1. A connector frame assembly for use with a compression tool, said connector frame assembly being an attachment for a compression tool for applying an axially directed compression force to a coaxial cable connector to attach the coaxial cable connector to a coaxial cable, said connector frame assembly comprising:
a connector frame having a connector for detachably coupling the connector frame to the compression tool;
a first receiver, attached to the connector frame, for engaging a first portion of the coaxial cable connector and for allowing a prepared end of a coaxial cable to be received into the first portion of the coaxial cable connector; and
a second receiver, attached to the connector frame, for receiving a second portion of the coaxial cable connector;
whereby upon applying a force by the compression tool, the first and second receiver move with respect to each other along the axis of the coaxial cable causing the first portion of the coaxial cable connector to compress with respect to the second portion of the cable connector for securing the cable connector to the coaxial cable.
2. The connector frame assembly of claim 1 , wherein the first portion of the coaxial cable connector includes a compression member and the first receiver is configured to receive the compression member.
3. The connector frame assembly of claim 2 , wherein the first receiver is a cable cradle.
4. The connector frame assembly of claim 1 , wherein the first receiver is a cable cradle.
5. The connector frame assembly of claim 1 , wherein the first receiver is configured to accommodate cables of various sizes.
6. The connector frame assembly of claim 1 , wherein the second portion of the coaxial cable connector includes a threaded nut rotatably secured to a post and the second receiver, receives the threaded nut rotatably secured to the post.
7. The connector frame assembly of claim 6 , wherein the second receiver is a sleeve.
8. The connector frame assembly of claim 1 , wherein the second receiver is a sleeve.
9. The connector frame assembly of claim 1 , further comprising the connector for detachably coupling the connector frame to the compression tool, wherein the connector is attachable to a ram of a compression tool for moving the connector frame.
10. The connector frame assembly of claim 1 , further comprising an orifice and pin for attaching the connector frame to more than one type of compression tool.
