Detailed Description
The present invention will be described in detail below with reference to specific examples and drawings, it being noted that the described examples merely represent preferred embodiments and should not be considered as limiting the scope of the present invention in any way. Those skilled in the art can make various modifications to the invention based on the design concept and the disclosure, and shall also cover the protection scope of the invention.
As shown in fig. 1, a connector according to the present invention, for example, a male connector 100, which is cylindrical, mainly includes a conductive terminal 110 made of metal, an insulating insert 120 made of plastic or the like, a conductive housing 130 made of metal, an insert clip 140, a C-shaped spring ring 150, an adapter 160, a pressing plate 170, and an adapter nut 180. The male connector has a plugging side on the left side in the figure for plugging of a mating connector 200 (see fig. 4) and a cable connection side on the right side in the figure from which a cable 190 is plugged into the connector.
The structure of each connector part will be described one by one.
The conductive terminal 110, i.e., the male terminal, has a cylindrical shape and is provided with a circular flange 111 on the outer circumference thereof. The flange 111 divides the conductive terminal 110 into a first interface side and a second interface side. The first interface side is pin-shaped to be inserted into the sockets of conductive terminals 210 (see fig. 4) (i.e., female terminals) of the mating connector 200. The second interface side is then used to crimp cable 190.
The insulating insert 120 is cylindrical for receiving the conductive terminals 110. The outer periphery of the insulating insert 120 is provided with an annular flange 121, and at least one axial projection 122, preferably two radially symmetrical axial projections, extending from the annular flange to the end of the insulating insert, i.e. the rear end in the figure. The inner side of the axial projection 122 is correspondingly an axial groove.
The conductive housing 130 is substantially cylindrical and has a rectangular, preferably square, flange formed on its outer periphery to secure the connector to a surface of an apparatus or a wall, particularly by screws or the like. The front end of the flange, i.e. the peripheral wall of the end of the connector 100 facing the counter connector, is provided with at least one, preferably a plurality of through holes in which balls 133 are accommodated, which as part of a self-locking system cooperate with recesses 233 of the inner peripheral wall of a cover 235 (see fig. 4) of the counter connector 200 to achieve a self-locking function.
The insert clip 140 includes a ring portion and at least one leg 141, preferably two legs or a plurality of legs.
The adaptor 160, which is substantially cylindrical, has a front end adapted to be fitted over a rear end (i.e., a cable connection side) of the conductive housing 130, and is threadedly coupled thereto. At the rear end of the adapter 160 there is received a seal 165 and a waterproof O-ring seal for sealing the cable.
An opening is provided in the rear end outer peripheral surface of the fitting nut 180, for example, a portion of the rear end outer peripheral surface is cut off, and two screw holes are provided on the walls at both ends of the opening. The opening exposes the cable 190 received in the fitting nut, particularly the metal layer of the cable stripped of the outer insulation. In order to provide EMC shielding, a pressing plate 170 made of a metal material is provided, and the pressing plate has an arcuate shape and screw holes are provided at both leg portions of the pressing plate. The screw hole of the pressing plate is in threaded connection with the screw hole of the opening through the screw, so that the cable, particularly a metal layer of the cable, is covered through the pressing plate, and EMC shielding is achieved.
Referring now to fig. 4, the assembly steps of the various components of the connector 100 are described in detail.
The insulating insert 120 is first inserted into the housing 130 from the cable connection side until the annular flange 121 of the insulating insert abuts against the shoulder at the inner periphery of the housing 130, and then the spring ring 150 is inserted into the housing 130 from the cable connection side in a compressed state until it abuts against the annular flange 121, releasing the spring ring so that it snaps into the annular groove 131 at the inner periphery of the housing 130, thereby limiting the axial displacement of the insulating insert. When it is desired to remove the insulating insert, spring ring 150 is merely pried out of groove 131 with a tool.
The cable 190 is passed through the adapter 160, which in turn crimps the cable 190 to the second interface side of the conductive terminal 110. The conductive terminal 110 is then inserted into the insulating insert from the cable-connecting side until the flange 111 of the conductive terminal abuts a shoulder on the inner periphery of the insulating insert 120, and then the insert clip 140 is inserted into the insulating insert 120 from the cable-connecting side with the legs 141 inserted between the insulating insert and the conductive terminal along the axial slots inside the axial projections 122 of the insulating insert, thereby gripping the conductive terminal.
The adapter 160 is threaded onto the end (rear end) of the housing 130 with the seal 165 contained therein surrounding the cable 190. An adapter nut 180 is screwed onto the rear end of the adapter 160, and a pressure plate 170 is pressed against the opening of the adapter nut 180 by a screw, thereby fixing the cable.
The structure of the mating connector, i.e., the female connector 200, is described below with reference to fig. 2 and 4.
Most of the components of the mating connector are similar to the connector and will not be described in detail herein. The main difference between the docking connector and the connector is that the housing 230 of the docking connector 200 does not have a rectangular flange similar to the housing 130 of the connector 100, and a cover 235 is sleeved outside the housing 230. The cage is cylindrical and has a groove 233 in its inner circumference for cooperating with the balls 133 of the housing 130 to form another part of the self-locking system. Further, a biasing member, i.e., spring 234, is disposed between the housings 230 and between the caps 235 and exerts a biasing force on the caps 235 to maintain the caps 235 in a locked position with the connector 100.
Referring next to fig. 5, an assembly process of the connector assembly composed of the connector 100 and the counterpart connector 200 is described.
When the mating connector 200 is plugged with the connector 100, the plugging side of the insert 220 of the mating connector 200 and the plugging side of the insert 120 of the connector 100 are plugged with each other, wherein the double cylinder wall design of the plugging sides of the two is such that the two are plugged with each other. The inserting sides of the two are forked, and the interdigitation ensures stable fixation. Meanwhile, the front part of the housing 130 of the connector 100 is held between the housing 230 and the cover 235 of the mating connector 200, and the cover 235 is pressed against the outer wall of the housing 130 due to the elastic force of the spring 234, so that the balls 133 on the outer wall are pressed into the grooves 233 on the outer wall of the housing 230, and the locking of the connector and the mating connector is realized. When unlocking is required, the cap 235 is pushed backwards, i.e. against its plugging direction, thereby compressing the spring 234, so that the balls are moved out of the grooves, thereby releasing the locking of the connector and the counter-connector.
The connector assembly according to the present invention including the male and female connectors is described above in detail, but the above-described specific embodiments are only preferred examples and should not limit the structure of the connector assembly of the present invention accordingly. Those skilled in the art will be able to make corresponding modifications to the specific structure of the male and female connectors according to the described embodiments of the invention.
