ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an angled coaxial connector module for mounting to a circuit board. More particularly, the invention relates to such an angled coaxial connector module which demonstrates relatively high electrical efficiency and which can be manufactured at relatively low cost.
BACKGROUND OF THE INVENTION
Coaxial connector modules are known in the prior art, as shown for example by U.S. Pat. No. 5,169,343. As seen in such patent, coaxial connector modules are employed to electrically connect high frequency signals to a circuit on a circuit board. However, prior art coaxial connector modules includes contact elements with multiple internal connections within a housing. Such internal connections resulted in decreased electrical efficiency, increased parasitic effects, and increased construction costs. These prior devices also included relatively complex housing constructions in order to separately channel multiple high frequency signals and shields, thereby resulting in increased construction and materials costs.
Specifically, in the aforementioned U.S. Pat. No. 5,169,343, within the housing, the center contact of each contact element includes two pieces, each inserted from a respective housing face into a channel, where the two pieces are soldered or welded together inside the housing, and where the channel is then filled with an insulating material. As can be appreciated, such an insertion and assembly process can be cumbersome and prone to error. Moreover, the quality of the joint between the two pieces can be suspect, resulting in electrical inefficiencies that can include unwanted resistive, capacitive, and/or inductive characteristics that might interfere with high frequency signals. As seen in the same patent, the housing includes a block of metal surrounding the insulation and acting as a shield. The use of a block of metal necessarily includes considerable time and expense in milling and drilling to form the required channels therein.
Accordingly, a need still exists for an angled coaxial connector module with contact elements that do not have internal connections that would decrease electrical efficiency. Also, a need exists for such a connector module which is constructed in a cost-effective manner from relatively inexpensive materials such that a relatively high state electrical efficiency is maintained.
SUMMARY OF THE INVENTION
The present invention satisfies the aforementioned needs by providing an angled coaxial connector module for being mounted to a circuit board. The connector module has a housing with a contact side for mating with a corresponding connector and a connecting side for mounting the connector module to the circuit board. The housing is constructed of an electrically insulating material.
At least one electrical contact element extends through the housing between the contact side and the connecting side. The contact element has an electrically conductive inner center contact, an electrically conductive outer shielding tube surrounding the inner center contact at least within the housing, and an insulating member surrounding the inner center contact at least within the housing and electrically isolating the inner center contact and the outer shielding tube. The inner center contact and the outer shielding tube each have a corresponding bent portion within the housing such that the contact side of the housing is at an angle with respect to the connecting side of the housing.
