Printed circuit board (PCB) connectors, for example, F-type connectors, BNC connectors, and the like, can be fixed to a printed circuit board for transmitting TV or CATV signals. Conventional connectors comprise an outer conductor and a center conductor that are soldered to the printed circuit board. The outer conductor typically comprises four corner arms that extend from a housing.
When welding the conventional connectors to the printed circuit board, the connector must be held in position by one hand of the person performing the soldering while the person solders with the other hand. As such, it is difficult to maintain the connector in a correct position with respect to the printed circuit board during soldering.
It is desirable to provide PCB connectors that can be assembled to a printed circuit board before soldering. For example, PCB connectors may include a gripping assembly configured to grip the printed circuit board.
In accordance with various aspects of the disclosure, a printed circuit board connector includes a cable attachment portion configured to be coupled with a cable and a printed circuit board attachment section configured to be coupled with a printed circuit board. The printed circuit board attachment section is configured to be coupled with the printed circuit board via a snap-fit connection.
In some aspects, the printed circuit board attachment section is configured to couple the connector with electrical ground and signal traces of the printed circuit board.
According to various aspects, the printed circuit board attachment section includes a pin forming a center conductor, and four corner arms forming an outer conductor. In some aspects, the four corner arms and the center conductor are configured to be coupled with the printed circuit board, and the printed circuit board has a hole pattern corresponding with the four corner arms and the center conductor. In various aspects, the printed circuit board includes a center hole configured to receive the center conductor and four outer holes configured to receive the four corner arms.
In accordance with various aspects, the printed circuit board connector includes a body member, and each of the four corner arms includes a first portion having a first end at the body member and extending from the body member to a mount. In some aspects, the mount includes a flange extending from a second end of the first portion in a direction away from the center conductor, and a finger extending from the flange in a direction away from the body member and parallel to the center conductor. The fingers are axially offset from the first portions relative to an axis of the center conductor. According to some aspects, the finger of the mount has an outer surface facing in a direction away from the center conductor, the outer surface includes a notch extending along a length of the finger, the finger includes a tapered free end, and an inner surface of the finger cooperates with a surface of the flange that faces away from the body member to define a shoulder.
According to some aspects, the four corner arms are flexible in a direction toward and away from the center conductor so as to function as a gripping assembly to couple the connector to the printed circuit board. In various aspects, as the four corner arms are inserted into corresponding holes in the printed circuit board, the four corner arms are urged inward in a direction toward the center conductor. According to some aspects, the four corner arms each include a tapered end and a notch adjacent the tapered end, and after the tapered end of each corner arm is inserted through the corresponding hole, the respective flexible corner arm is configured to return to a rest configuration as the notch is aligned with the printed circuit board.
In accordance with some aspects, the printed circuit board attachment section is configured to grip the printed circuit board, via the snap-fit connection, to maintain a desired alignment of the four corner arms and the center conductor relative to a plane of the printed circuit board.
According to various aspects, the printed circuit board connector is one of a straight mount jack and a right angle jack and/or the cable attachment portion is configured as one of an F-type connector and a BNC connector.

In various aspects, the mount may include a flange extending from a second end of the first portion in a direction away from the center conductor, and a finger extending from the flange in a direction away from the body member and parallel to the center conductor. The fingers are axially offset from the first portions relative to an axis of the center conductor.

Exemplary embodiments will be described with reference to the following drawings.
The detailed description provided below in connection with the appended drawings is intended as a description of the present examples and is not intended to represent the only forms in which the present example may be constructed or utilized. The description sets forth the functions of the example and the sequence of steps for constructing and operating the example. However, the same or equivalent functions and sequences may be accomplished by different examples.
The connector 100 may include a body member 102, a cable attachment portion 104, and a printed circuit board attachment section 106. The cable attachment portion 104, where an external connection through a mating connector (not shown) may be made, extends from a first end of the body member 102. It should be appreciated that the cable attachment portion 104 may be configured as an F-type connector, a BNC connector, or the like. The printed circuit board attachment section 106 extends from a second end of the body member (e.g., an opposite end or an end disposed at 90° relative to the first end) and couples the connector 100 to the electrical ground and signal traces of a PCB (or alternatively a printed wiring board) upon which the connector 100 is disposed.
The printed circuit board attachment section 106 includes four corner arms 110 forming an outer conductor. The printed circuit board attachment section 106 also includes a center conductor 112 configured as a pin that may be coupled to a PCB trace (not shown). The four corner arms 110 are constructed so as to be flexible in a direction toward and away from the center conductor.
The four corner arms 110 and the center conductor 112 are structured and arranged to be coupled with a printed circuit board 190 having a corresponding hole pattern (
As best illustrated in
Referring to
In use, the four corner arms 110 of the printed circuit board attachment section 106 may function as a gripping assembly to couple the connector 100 to the PCB 190 before soldering. The center conductor 112 and the four corner arms 110 are aligned with the corresponding holes 194 in the PCB 190. As the four corner arms 110 are inserted into the outer holes 194, the tapered ends 140 of the offset fingers 134 engage the printed circuit board, the flexible corner arms 110 are urged inward in a direction toward the center conductor 112.
After the tapered end 140 of each finger 134 is inserted completely through the corresponding hole 194, the respective flexible corner arm 110 returns to its rest configuration as the notch 138 is aligned with the printed circuit board 190. In their rest configurations, the flexible corner arms 110 grip the printed circuit board 190 in the notches 138. Further, the shoulder 150 engages a surface of the printed circuit board 190 to grip the PCB 190 between the shoulder 150 and the tapered end 140.
The PCB mount 130 is thus configured to grip the printed circuit board 190, which maintains a desired alignment of the four corner arms 110 and the center conductor 112 relative to a plane of the PCB 190 before soldering the connector 100 to the PCB 190. Also, there is no need for a person doing the soldering to hold the connector 100 while soldering. As a result, a connector 100 according to various aspects of the disclosure makes the soldering process easier and quicker. The connector 100 may also provide better contact by maintaining the position of the corner arms 110 and the center conductor relative to the plane of the PCB 190 with the gripping performed by the PCB mount 130.
It should be appreciated that, in some embodiments, the connector 100 may be designed to be coupled with the printed circuit board 190 without soldering. For example, the flexible corner arms 110 and, in particular, the PCB mount 130 can be constructed so as to provide flexibility and a gripping force that ensure mechanical and electrical coupling of the connector 100 to the printed circuit board 190.
