Description

ELECTRICAL CONNECTOR WITH INTERNAL SWITCH

In high frequency and high power electrical applications, the application of power to the coupling device carries inherent risks that are always important to both the manufacturer and the user of such a device. The output should be provided in such a way that it will not damage the device and should be provided in a way that provides a safe device for the user. For example, when high output (i.e. kilowatt) RF signals are transmitted along a cable disconnected from the load, i.e. in an open circuit, energy can return to the signal source, thus destroying identity. Also, if the conductive material is located very close to the end of the cable to which the high power signal is applied, the signal can be arced across the air gap with the conductive material. This can pose a significant risk of electric shock, damage to the device, fire, etc.

The other relates to the risk of electric shock for users of high power devices. When power is provided along a cable disconnected from the load, the user can make a physical connection to the "thermal" end of the cable. This can occur, for example, inadvertently in direct contact with the central conductor of the cable with the central conductor of the cable or by inadvertent contact with the central conductor and the hand tool. Regardless of the manner in which they are in contact, enough power can be provided by the cable to cause serious damage or killing to a person. Therefore, contact prevention with the central conductor of the cable is very important.

Unfortunately, users of high power RF devices have typically left their own resources to limit the damage associated with the application of high power signals to open circuits. Most users are very aware of damage and are careful to connect the load to the signal source before providing output. Human error, immaturity and accidents are frequently causing serious injury and damage to the device.

Thus, there has long been a desperate need for a technique for simple and effective mechanical means to ensure electrical signal sources that are not provided in open circuits. In particular, there is a need for a technique for electrical connectors with internal switches, especially connectors for use in high power RF applications, so that the electrical source can be contacted by the conductor passageway when mating connectors are coupled together.

Purpose of the Invention

It is therefore a primary object of the present invention to provide an electrical connector having an internal switch that allows an electrical signal source to contact the conductor passageway when the mating connectors are engaged together.

It is another object of the present invention to provide an electrical connector having a switch actuating portion to operate an internal switch to the mating connector by contacting the electrical source only through the conductor passage when the mating connector is engaged together.

It is a further object of the present invention to provide an electrical connector with an internal switch that is provided with a conductor passage so that when the mating connectors are joined together they only contact the electrical source with the conductor passage, where the internal switch is blunt, such as a human finger. It cannot be easily disconnected by connecting the switch with an object.

It is yet another object of the present invention to provide an electrical connector that reduces the risk of unexpected shocks associated with high power electrical applications.

It is another object of the present invention to provide an electrical connector having a simple and inexpensive internal switch.

Another object of the present invention is to provide an electrical connector having an internal switch that is easily assembled.

It is a further object of the present invention to provide a new method of preventing the connection of an electrical signal source to an open circuit using a connector with an internal switch.

These and other objects of the present invention will become apparent from the following detailed description.

2 is a right side view of FIG. 1.

3 is a side view of a mating connector comprising a right angle adapter according to the present invention applied for coupling with the connector shown in FIG.

4 is a cross-sectional view of the mating connector shown in FIG.

5 is a partial cross-sectional view illustrating a mating coupling between the connector of FIG. 1 and the mating connector of FIG. 4.

The electrical connector of the present invention is arranged with respect to the concept of providing a connector having an internal switch actuated by the switch actuating portion of the mating connector when the mating connector is engaged together. The switch generally blocks open electrical passages to control output application through the connector. So when the connector of the invention is connected to the mating connector according to the invention, ie when the load is connected to the signal source, the signal source is connected to the connector by the connection of the switch actuation part of the mating connector with an internal switch. When the mating connector is removed, its switch actuation returns the switch to its normal open state and retracts from the switch to disconnect the signal source from the connector. As a result, a signal can be provided from the signal source to the connector when the mating connector is engaged with the connector of the present invention. Preferably all risks of human injury and damage to the device are eliminated.

In particular, the connector of the present invention includes a body and a switch disposed in a hole in the body. The switch has a lead connected to an electrical circuit for controlling the contact of the electrical signal to the central conductor of the connector. In the coupling of a connector with a mating connector, the mating connector is such that the electrical signal flows through the center conductor to the center conductor of the mating connector while the switch is in an open state where the contact of the electrical signal to the center conductor is generally interrupted. It will be in a closed state that is connected to the central conductor.

Preferably, the switch is disposed in a hole near the body opening so that the mating connector portion can enter the opening and connect to switch the switch from a generally open state to a closed state. The switch, however, connects with other element (s) axially moving to operate the switch. The switch can be very versatile and the mating connector can be connected to any necessary part of the switch to change the switch state. That is, the mating connector can be connected to the pole of the switch or can be fixed to the switch arm.

The body includes an opening that leads from the outer face of the body to the hole. The openings are sized to receive the conductors connected to the leads of the switch. The conductors connect the switch leads to the electrical circuit to control the application of the electrical signal to the central conductor. The conductor connects the switch leads to the electrical circuit to control the application of the electrical signal to the central conductor.

In a preferred embodiment, the body comprises a mating shell and an outer shell and a hole in the switch is formed between the mating shell and the outer shell.

Preferably the mating shell comprises a protrusion therein for installing the switch. The switch is fixed to the mating shell by helical coupling to the inner surface helix of the protrusion and the outer face of the switch.

The mating connector has a body including a switch actuating portion. The switch actuating portion has a width extending axially from the body to connect the switch with the mating connector coupling with the connector. Preferably the body of the mating connector comprises an inner shell portion and a coupling shell disposed around the inner shell. The coupling shell is axially biased toward the mating end of the mating connector by a compression spring disposed between the inner shell and the coupling shell. In this preferred embodiment, the end of the coupling shell is a switch which actuates the part for connecting the switch.

Preferably the inner shell comprises an opening which is characterized in that the locking element is arranged in the opening with the part in an inward radial force exerted beyond the inner face of the inner shell by the first face of the coupling shell. The coupling shell includes an inclined surface adjacent to the first face. In the axial movement of the coupling shell away from the mating end, the inclined surface is in line with the opening so that the locking elements are returned into the opening relative to the inclined surface.

The connector includes a groove formed therein for receiving the locking elements of the mating connector. The locking elements are pressed into the grooves by the first face dropping the coupling shell to form a male and female coupling between the mating connector and the connector.

The invention further comprises a method of connecting an electrical signal to an electrical connector in accordance with the mating of the connector with the mating connector. The method includes providing an electrical connector in accordance with the present invention, wherein the mating connector is coupled with the mating connector to connect the central conductor of the mating connector to the central conductor of the conductor and the mating conductor to switch the switch from the normally open state to the closed state. Works.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS For a better understanding of the present invention, together with other objects and shapes and advantages, preferred embodiments will be described by reference to the drawings in which:

The present invention will be described with respect to a preferred embodiment such as or suitable for installation in an instrument panel such that electrical connections between the electrical singer and the electrical device can be removed. Preferably the connector includes a switch that operates an external switch to control the flow of current through the connector depending on whether the mating connector is secured to the connector. Briefly described, the present invention will be described herein in terms of particularly preferred embodiments. However, those skilled in the art will recognize that the advantages of the present invention can be embodied in many connector designs. Thus, it is intended that the present invention not be limited to the specific embodiments described, but include any modifications to the various connector designs and designs.

1 to 2, a preferred embodiment of the connector 1 generally comprises a connector body 2 comprising an outer shell 4, a mating shell 6 and an end shell 8; A micro switch 10 disposed in the switch body 2; A first insulator 12, a second insulator 14, and a third insulator 16; Central conductor 18; Mounting plate 20; And gasket 22. The outer shell, mating shell, end shell and mounting plate are preferably made of copper and sheeted with nickel. The connector is preferably formed of copper and sheet metal. The insulator portion is preferably formed of an insulating material such as known teflon. The end 30 of the central connector 18 at the plug end 28 of the connector is connected, for example, with the mating connector 52 or by soldering the appropriate conductors 54, 56 of the electrical signal source 50 and the central connector. It is disposed outwardly from the bottom face 32 of the mounting plate 20 to facilitate the formation of the electrical connection 58 between the ends 30 (see FIG. 5). At the socket end 24 of the connector the end 26 of the central connector 18 is disposed radially inward with respect to the top face 34 of the end shell 8.

As will be described in detail below, the end shell 8 at the socket end 24 connects the electrical connection 66 between the central conductor 18 and the electrical device 68 via the central conductor 70 of the mating connector. It is provided with an annular groove 36 for fitting the locking elements 60, 62 of the mating contact 64 (see FIGS. 4 and 5). However, other mating connection forms and methods are understood to be apparent to those skilled in the art. For example, instead of the ball locking device of the preferred embodiment, screw engagement can be used for mating connectors that include a switch actuated with a spiral in the end shell. Other forms of connection and connection methods will already be apparent to those skilled in the art.

As shown in FIG. 1, the mating shell 6 and the mounting plate 20 are preferably formed in two pieces fixed together, for example by soldering. It is also possible to form the mating shells and mounting plates in any way. Holes in the mounting plates 38, 40, 42, 44 facilitate installation of the connector 1 to the instrument panel 72 (see FIG. 5), for example, through suitable fittings such as screws 44. The annular gasket 22 is formed of a suitable gasket material and secured to the outer end of the mating shell 6 using, for example, an adhesive to fit between the connector 1 and the machine plate 72.

The mating shell 6 is generally cylindrical in shape with a stepped inner surface with an axial opening. The first jaw portion 82 of the inner surface 80 provides a stop for the bottom surface 84 of the end shell 8. The proximal face of the mating shell is helix to make a connection between the mating shell 6 and the end shell 8. The spirals 86 on the proximal face are joined correspondingly to the spirals 88 on the bottom of the end shell 8. The end shell and mating shell are thus assembled together by rotation of the end shell 8 and mating shell 6 with each other until the bottom face 84 of the end shell is fitted with the jaw 82 of the mating shell.

The second jaw portion 90 of the mating shell provides a contact surface for the jaw 92 formed in the second insulating portion 14. The contact of the jaw 90 with the jaw 92 at the second pickled portion provides a means for accurately positioning the second insulating portion with respect to the mating shell in the opening. The second insulator portion includes grooves 94 on the outer surface to receive the gasket 96. The gasket ensures a closed-fastening contact between the second insulating portion and the mating shell.

The first insulated portion 12 includes a first jaw lined with the jaw 82 in the mating shell and in contact with the inner end 98 of the second insulated portion and ends when the end shell is secured to the mating shell. It contacts the bottom surface 84 of the shell. The second jaw portion 102 is formed in the first insulating portion 12 to contact the radially inwardly extending protrusion 104 at the generally inner side 106 of the cylindrical end shell. Thus, the first and second insulators are provided at the end shell and mating shell, respectively, between the protrusion 104 of the end shell and the jaw 100 of the end 84 and between the jaw 82 and the jaw 90 of the mating shell, respectively. Locked in the axial position.

The inner side 108 of the first insulating member forms a stepped cylindrical opening through which the central connector 18 extends. The central conductor 18 is positioned axially in the opening by engaging the first jaw 110 in the central conductor and the jaw 112 in the first insulation. The third insulating portion 16 contacts the lower surface with the second jaw 114 of the central conductor and the end 116 of the first insulating portion to fix the central conductor in axial movement with respect to the body. The top face 118 of the third portion is arranged to face the third jaw 120 of the central conductor 18 and the first jaw portion 122 on the generally cylindrical inner surface of the second insulating portion.

Thus, the first, second and third insulated portions engage the center conductor in the axial position and secure the center conductor so that the end 24 of the center conductor is axially recessed relative to the socket end 130 of the first insulated portion. Is located. The opposite end 30 of the central conductor is positioned to extend axially from the plug end 132 of the second insulating portion. The insulator and the center conductor are positioned axially relative to the mating and end shells by combining the first and second insulators in positions opposite to the mating and end shells as described above. Preferably this structure provides easy assembly and accurate positioning of the connector elements with respect to each other.

Referring to FIG. 1, the outer face of the mating shell is adapted to install at least one micro switch, which in a preferred embodiment is a model number SAIRV20 switch manufactured by eaton corporation. In a preferred embodiment, only one micro switch is coupled to open and close the connection between the electrical signal source 50 and the central conductor 18 of the connector 1. In another embodiment, however, two or more switches are included in the design with the leads of the switches wound in line between the electrical signal sources. This connection may be overridden by one of the switches with the device, preventing the possibility of connecting the source to the central connector without connecting to the mating connector. Preferably the switch can be connected to the splitting circuit to open and close other conductive passages. In another embodiment including two switches, the switches will be positioned about 180 degrees apart to balance the forces acting on the mating connectors.

Referring to FIG. 1, at the first end of the mating shell, a radially extending installation protrusion 150 is formed to have a hole through which the pillar 152 of the micro switch can pass. The inner face of the hole is provided with a helix 154 that joins a helix corresponding to the helixed portion 156 of the switch. Thus, the switch engages with the switch helix and the mounting protrusion by rotating the switch until the spiral portion of the switch moves through the hole so that the end 158 of the body portion of the switch engages the bottom surface 160 of the mounting protrusion. Installed in the shell and fixed.

At the second end of the mating shell, the shell is formed with increasing diameter 159, and the hole 161 is formed past the increasing diameter. The apertures are sized to allow conductor leads 162 and 164 to pass through the outer or conductor body in the switch leads. The conductor lead causes the switch to pass through the central conductor 18 in an electrical circuit for electrically opening and closing the conductor. The leads can be provided with suitable conductors 52 at the ends that allow easy connection to the electrical circuit or can be connected directly in the circuit by soldering depending on the application conditions.

The outer face of the reduced diameter is generally provided as a helix 170 for engaging the corresponding helix 172 on the inner face of the rear end of the cylindrical outer shell 4. The outer shell 4 is thus fixed to the mating shell by helical engagement and the outer shell mates until the bottom surface 176 of the outer shell engages the first shell portion 178 on the outer side of the mating shell. Rotate about Since the outer shell is secured to the mating shell, the switch body is disposed in an annular hole 180 formed by the mating shell and the outer shell, the conductor lead of the switch extending outwardly from the body portion through the hole 160.

The end of the outer shell is provided with a reduced diameter portion 182 positioned axially beyond the mounting protrusion 150 of the mating shell. This decreasing diameter along the annular projection 192 formed in the end shell forms an annular opening 184 in which the switch post 152 is disposed, with the connector uncoupled. Thus, when the connector is in the unengaged position, the switch post extends axially beyond the top face of the protrusion 150, but the end face 190 of the outer shell and the end face of the annular protrusion 192 formed in the end shell ( With respect to 194, it is in a state of being recessed axially in the opening 184. Preferably such a connection protects the switch post from inadvertent connection and thus prevents accidental actuation of the switch such that the signal source contacts the central conductor when the switch is not engaged.

The structure described above allows for easy and effective assembly of the connector 1. Initially the first, second and third insulator portions are located throughout the central conductor with the jaws 110 and 114 engaging the corresponding faces in the insulation portions. The end shell is thus positioned throughout the first insulated portion with the protrusion 104 disposed opposite the jaw 102. Thus, the mating shell, together with the switch and mounting plate connected there, is engaged with the end shell through the engagement defects of the spirals 86,88. The outer shell is thus fitted to the connector via the spirals 170, 172.

3 and 4, coupling sleeve 200, first inner shell 202, end shell 204, insulation 206, 208, center connector 70, compression spring 210 and ball bearing lock A preferred embodiment of a mating connector 64 including elements 60 and 62 is shown. As shown, the central connector 70 is disposed at an axial position fixed in the opening formed by the leading edge and electrically connected to the connector 214 received in a known right angle adapter 212. The right angle adapter includes a helix 215 at its end that engages the helix 216 on the inner face of the inner shell to secure the mating connector to the right angle adapter.

The inner shell portion 202 is generally formed to include a portion that is cylindrical in shape and defines openings 220 and 222 in a star sized to receive a ball bearing locking element. The portion forming the opening includes an inclined inner surface 224 such that the diameter of the opening is reduced towards the inner surface 228 of the inner shell. Therefore, the ball bearing locking element can be received at the top portion of the opening, but the bottom portion of the opening has a diameter such that the ball bearing locking element extends inward beyond the inner face 228 of the inner shell there.

The inner shell portion includes an increasing diameter portion 230 at the rear end with a circumferential protrusion 232 on the outer face. The jaw 234 is formed outside of the inner shell portion. The jaw provides a face opposite the bottom of the cylindrical compression spring 210 receptacle. The top of the compression spring engages the jaw 236 that is formed inside a generally cylindrical coupling sleeve 200 disposed around the inner shell portion.

End shell 204 includes helix 240 that engages a corresponding helix 242 at the outer face end of the inner shell. The end shell portion includes an increased diameter portion 244 that forms a jaw 246 for engaging a piece of jaw 248 on the inner surface of the coupling sleeve. In assembling the mating connector, the helix 240 in the end shell is engaged with the helix 242 in the inner shell and the end shell contacts the jaw 252 in which the end face 250 of the end shell is in the inner shell. Until it rotates against the inner shell. When the end shell fits into the inner shell, the jaw 246 in the end shell receives the opposing jaw 248 in the coupling slave and thus compresses the coupling slave, which compensates axially for deflection of the compression spring. . Therefore, the compression spring exerts a spring force on the jaw 236 on the inner face of the coupling slave to continuously bias the coupling slave against the jaw 246 of the end shell. The spring force of the compression spring is selected to be overcome by physically applying a force to the coupling slave which compensates axially in the direction of the end 256 of the mating connector.

The coupling slave includes a decreasing diameter portion 258, an increasing diameter portion 260 and a switch actuating portion 262. The inner face of the reduced diameter, which is joined with the opposite outer face portion of the inner shell, forms a cavity 264 in which the compression spring is disposed. The increased diameter includes the first inner face 266 located directly above the openings 220, 222 in the inner shell, in which the ball bearing locking element is disposed. The first inner face forces the ball bearing inward radially to extend its position beyond the inner face 228 of the inner shell inward radially as shown in FIG. 4. The inclined inner surface 268 of the larger diameter is located near the opening towards the end 270 of the connector.

The connection between the connector 1 and the mating connector 64 opposes the deflection of the compression spring 210 and towards the end 256 of the mating connector until the end 272 of the coupling slave contacts the protrusion 232. By inserting the coupling slave 200. This actuation causes the inclined inner surface 268 of the coupling slave to line up with the openings 220, 222 so that the ball bearing locking element is inward relative to the inner surface 228 of the inner shell and the inclined side of the coupling slave. Reduce to oppose the inner face.

When the ball bearing enters the opening towards the outer shell and frees past the inner face 228 of the inner shell, the mating connector is connected to the connector (1) until the position of the ball bearing corresponds to the position and axis of the groove 36 in the end shell. End shell). Similarly, the central conductor 70 of the mating connector is housed in line with the central conductor of the connector 1 to form an electrical path through the connector 1 and the mating connector 1.

The coupling sleeve is then released and the compression spring presses the coupling sleeve toward the end 270 of the mating connector so that the first inner face 266 of the coupling sleeve is in particular the inner face of the inner shell as shown in FIG. 5. Force the bales 60, 62 outward relative to 228 and into the grooves 36 in the connector 1. The fastening of the ball bearing together with the groove locks the mating connector 64 in the connector 1.

Preferably, when the mating connector 64 is engaged with the connector 1, the switch actuating portion 262 of the coupling sleeve extends into the opening 184 in the connector 1 in which the switch post 152 is disposed. do. The switch actuator is sized to press the switch pillar such that the end face 280 of the switch actuator contacts the end of the switch pillar 152 when the engagement is made and changes the switch from the "open" state to the "closed" state.

The switch 10 is thus generally changed from an open state to a closed state in the connection of the mating connector of the mating connector to connect the electrical signal source 50 to the central conductor 18. When the mating connector retracts the coupling sleeve and retracts from the connector 1, the switch actuating portion 262 of the coupling sleeve is removed from the connection with the switch pillar 152, and the tm position pillar is its normal "open". It returns to that position in the opening 184 to return the switch to the state.

In this structure, when the connector 1 is engaged with the mating connector 64, it is possible to connect an electrical signal only to the central conductor 18 of the connector 1. Thus, the end of the center conductor 18 is never "hot" when it is dropped from the mating connector. In addition, by positioning the ends of the switch posts 152 in the inner axis with respect to the top surfaces of the outer shell 4 and the end shell 8, the switch can not be ignored in connection with human fingers or blunt devices. .

Thus, an electrical connector is provided that eliminates the risk associated with providing a high power electrical signal to an uncoupled connector. The connector includes an internal micro switch disposed in the connector body to connect an electrical signal source to the connector when coupled with the mating connector. The mating connector includes an electrical connection between the electrical signal source and the connector's central connector, including a switch actuating portion extending into the opening formed in the connector to press the pole of the switch so that the switch generally changes from an "open" state to a "closed" state. Achieve. In the retraction of the mating connector, the switch returns to its normal "open" state and thus breaks the electrical connection between the connector's central connector and the electrical signal source. The risk of human damage or equipment damage resulting from inadvertent contact with the end 26 of the central conductor or from arcing of electrical signals at the central conductor is eliminated with a simple and low cost design.

However, the embodiments described herein are only some examples for realizing the present invention and are listed in the above-described manner and not limited thereto. For example, the number of internal switches may not be limited. It will also be apparent to those skilled in the art that the shape of the present invention may vary connector design to vary any form of electrical signal. It will be apparent that many other embodiments will be apparent to those skilled in the art without departing from the spirit and scope of the invention.
