Abstract

An improved terminal BNC T Adaptor disclosed herein is featured for having an improved auto termination installation, which comprises of a female contact in connection with a male contact. Extending both outward and downward from the two lateral sides of the female contact is an oblique panel. Prior to connecting the BNC plug, by means of elasticity the panel will get in touch and press onto a conductive element with ceramic resistance to enable the male contact, the female contact, the conductive element and the ceramic resistance to form a noise blocking circuit, so as to achieve the effect of auto termination. On the contrary, after connecting T Adaptor with BNC plug, the panel will be pushed away from the conductive element by the male contact inside the BNC Plug, and thus stop the noise blocking from functioning. The other end of the ceramic resistance is also connected with an improved conductive voltage cover, to the bottom of which a tether is connected by a retention post to achieve a better grounding effect.

Claims

1. An auto termination BNC T adaptor, comprising:

a) a housing having BNC jacks;

b) a male contact having connection means on a bottom portion extending into the housing;

c) a female contact located in the housing and attached to the bottom portion of the male contact by the connection means, the female contact having a socket and wing panels which extend obliquely downward from two lateral sides of the socket, each wing panel having an oblique guide plane counter-folded at an extreme end thereof, and also having an arc-shaped section defining a downward facing opening located on counter-folding points of the guide plane;

d) a pair of contact feet facing one another and extending downwardly from each of the wing panels between the socket and the guide plane, the contact feet defining contact points which extend below a line connecting the two counter-folding points;

e) a conductive element located in the housing having a contact section and conductive pieces extending outward from two lateral sides of the contact section;

f) a ceramic resistance in electrical contact with the contact section of the conductive element;

g) insulation means located in the housing so as to electrically insulate the housing from the male and female contacts, the conductive element and the ceramic resistance; and

,

h) a conductive voltage cover located in a bottom of the adapter so as to be in contact with the ceramic resistance.

2. An auto termination BNC T adaptor as described in claim 1, in which the connection means comprises a male thread formed on the bottom portion of the male contact.

3. An auto termination BNC T adaptor as described in claim 2, further comprising a female thread formed on the socket of the female contact for the attachment of the male thread at the bottom portion of the male contact.

4. An auto termination BNC T adaptor as described in claim 1, in which the wing panels of the female contact define a wrinkled/folding plane for strengthening purpose located in the space between the pair of contact feet which are facing one another on the wing panel.
