Abstract

A female coaxial cable electrical connector includes an electrically conductive barrel or shell enclosing a contact carrier assembly. The contact carrier assembly consists of a cap member enclosing a subassembly that includes an elastomeric sleeve or tubing compressively but yieldably mounted over the contact receiving arms of a base member with an electrical contact secured between opposing ones of the two contact receiving arms. The electrical contact is formed from electrically conductive material, and includes two opposing half-sections that are mounted between the contact receiving arms of the base, and have side wing portions contacting one another, with opposing longitudinal semicircular grooves of the half-sections of the contact together forming a circular pathway for receiving a male electrical pin or the center conductor of a coaxial cable. When such a pin or center conductor is inserted into the electrical contact, the elastomeric sleeve initially yields on inward pressure to permit insertion of the pin, while maintaining sufficient inward pressure to force the semicircular grooves of the electrical contact to mechanically contact and surround the circumference of the male pin or center conductor, for substantially the full length of its insertion, thereby insuring a low resistance electrical contact therebetween.

The design of the base member 8 will be explained with reference to Figs. 5A to 5E. The mysterious base member 8 includes a circular lowermost portion 40 from which the terminal receiving arms that are oppositely spaced and vertically aligned are extended. The inner wide reverse wall of the arm portion I is configured to receive a reverse half of the end + 6 and each of the outer side walls of the terminal receiving arm 42 has a radius, in FIG. 5D, Have the best display. The arms 42 further include a longitudinal semi-circular groove 44 on either side of the flat wall portion 45. The grooves 44 are: semi-circular outer walls or ribs 31 for receiving the groove % of the reverse half section 33 of the terminal 6. The flat wall portions 45 are opposite to the side wall portions 37 of the terminals 6. The topmost outer wall and the inner wall of the arm portions 42 include beveled weirs 46, 48 on either side of the distal end portion, respectively. The large diameter circular lower portion contains a centered chisel perforation 50 as shown. The length of the base member 8 is adjusted for use with a vertical or horizontal RF connector or housing 1G. In general, for use in a water housing H), the length of the base member 8 must be longer than the length used in the - vertical housing or crucible 10. Another embodiment 9 of the present invention is 200845506 2 shown in the configuration of FIG. 2 'The base member 8 of the present example will be configured or used to use a vertical RF connector housing or 埠 (7) The base member 8 of the 1C configuration '® 6 will grow by incorporating an extension 52 from the lower circular portion 40, as shown, in the two-level horizontal RF connector housing or 槔ι〇. The present embodiment 'the earth's component 8 is composed of a single dielectric plastic material device, and any suitable plasticity sufficient to minimize the bending resistance due to the softness must be sufficient for the plastic material of the base member 8 to An internal force is applied to each of the terminal receiving arms 42 to move the arms 42 to each other, as will be explained in more detail below; when the inward force is reduced, it is necessary Remember to their resting position (cafe pGsitiGn) (four).义疋朝 = The operation of this coaxial connector will be explained. When the male pin or the center conductor of the coaxial coaxial 中 中 中 被 被 被 被 被 被 - - - - RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF RF The elastic sleeve 4 is combined with a strangely directed radially inward pressure for forcing the electrical terminal two (four) halves 33 1 to contact. The inward force or pressure will cause the 2 private child 1 to push the towel of the masterbatch 6 . The base material 8 will be flexed inwardly by the force provided by the elastic sleeve 4 (for the forced end). The two halves 33 will: our groove 30 # The male conductor 'contacting the coaxial cable' is used to ensure a very low resistance between them. ^ For the entire length of the inserted male pin or conductor, it will remain almost (10) between the + + + + and the male or coaxial central conductor. Mechanical contact of 200845506. In other words, each of the half sections 33 will have their individual grooves 30 almost half the length of the male or central conductor. In this way, the lowest possible resistance connection is maintained between the electrical terminal 6 and the mating male or central conductor of a coaxial cable.

It should also be noted that the preferred use of the beryllium copper material of the female terminal 6 provides "memory". For example, when a large size male pin or middle conductor is inserted, the groove #3G# radius is increased to accommodate the size of the male pin or the center conductor of the coaxial cable. The terminal + 6 will still mechanically contact a large number of surfaces of the male pin of the coaxial central conductor. After the pins or conductors are removed from the connector assembly 12, the crimped copper terminal material of the trenches will return to their original or rest radius, thereby allowing the terminal 6 to be implemented smaller than previously inserted. The wire size is the function indicated by the wire size of the male pin or the coaxial center conductor. It should be noted that there are several common cable TV system wire sizes that are expected to use this coaxial connector. The center conductor of the RG-59 coaxial cable has a wire size of 〇·032 inches, and the RG·6 coaxial cable has a diameter of 0.04 inches.

The radius of these grooves 3() is $英英. The radius of the grooves 30 is 〇 () 15 inches. Therefore, when the two halves 33 of the terminals 6 200845506 are opposite to each other and the side flap portions 37 are in contact, the inner diameter of the circular groove 30 formed is 〇·〇3 inches. Through the prototype of the project, it has been determined that the terminal June 6 can be easily expanded to accommodate or receive the male pin when receiving a 32-inch male pin. It has also been found that the terminal 6 can be easily expanded to accommodate a 公 4 〇 inch male pin. In addition, it has been determined that after removing a wire of a 0. 04 inch pair, the terminal 6 returns to its original previous dimension via the memory factor of the beryllium copper material.
