RF latching connector with polymer spring |
(57) This invention relates to an RF connector latching system. Some RF connectors are designed with a latching system to ensure that male and female
connectors remain locked together to prevent accidental disconnection. With some connectors
this locking system comprises a sprung loaded sleeve which requires forced axial movement
to permit separation of the two connectors. The current design as shown in Fig 1 and 2 incorporates a wire formed compression
spring trapped between two locking washers which allows forced movement in two axial
dimensions permitting release of the mating connector at the extremities of movement. This sprung mechanism is difficult to assemble and inspect after assembly. This invention relates to an injection moulded spring as shown in Fig 5 which has
a semi-circular form so that two springs can be easily assembled from each side of
the connector as shown in Fig 4 and held in place with an injection moulded sleeve
as shown in Fig 3. The spring locates in two groves to lock to the inner body and outer latching sleeve
as shown in Fig 6.

Fig 1 illustrates a conventional connector with a transparent latching sleeve showing
the wire formed spring and locking washers.
Fig 2 illustrates the conventional latching sleeve, spring and locking washers subassembly.
Fig 3 illustrates the invention showing the injection moulded springs in position
through a transparent injection moulded sleeve.
Fig 4 illustrates the invention showing the injection moulded springs in position
without the injection moulded sleeve.
Fig 5 illustrates the injection moulded spring.
Fig 6 illustrates a sectional view of the invention showing how the spring latches
with the latching sleeve and inner body.
1. A latching RF connector incorporating an injection moulded spring.
2. A connector as described in 1 with an injection moulded sleeve to ensure location
of the injection moulded springs.
3. A connector as described in 1 with two semi-circular injection moulded springs.
4. A connector as described in 1 with one semi-circular injection moulded spring.
5. A connector as described in 1 with one circular injection moulded spring.
