Abstract
The utility model discloses a connector needle shaft device, which comprises an inner tube, wherein a spring is fixed on one end in the inner tube, and the inner tube provides a motion space for an objected which is arranged in the inner tube, a needle shaft which is arranged in the inner tube and is connected with the spring, and the needle shaft does linear motion in the inner tube under the function of external force, and one end of the needle shaft, which is connected with the spring, is provided with a plurality of contact pieces at equal interval, and the contact pieces contact with the inner tube, thereby reducing the resistance value of the connector. A needle shaft and a barrel body of the connector needle shaft device keep stable contact, thereby leading the connector to get lower and stable resistance value.
Description
[technical field]
The utility model relates to a kind of connector pin shaft device, particularly about the inner connector pin shaft device that connects battery of a kind of portable electric appts.
[background technology]
Needle shaft is one of parts of connector, directly contact during use with battery, be used for conduct power, general portable electric appts requires its connector resistance lower, because the interior pipe contact area of the resistance of connector and needle shaft and connector is inversely proportional to, so in order to reduce the resistance of connector, need to increase the contact area of needle shaft and interior pipe, existing thimble-type connector pin shaft device, People's Republic of China's patent ZL200620066779.8 for example, described needle shaft bottom is an inclined-plane, it is connected with a spring, when described connector is worked, thereby described needle shaft is to spring one lateral movement compression spring, so simultaneously be subjected to spring simultaneously and be compressed the elastic force that is produced because spring is compressed described needle shaft, because described needle shaft bottom is an inclined-plane, so described needle shaft produces a lateral thrust under the thrust of spring, thereby the contact area that increases described needle shaft and described interior pipe has reduced the resistance of connector, yet when needle shaft during to spring one lateral movement, because the needle shaft bottom is an inclined-plane, so can cause the spring motion irregular, thereby spring props up the place that needle shaft will contact with interior pipe originally sometimes, cause its impedance to increase, reality will become loose contact on using.
In view of this, be necessary to provide a kind of connector pin shaft device in fact, thereby needle shaft keeps stable contacting to make connector obtain lower and stable resistance with stack shell.
[summary of the invention]
The purpose of this utility model is to provide a kind of connector pin shaft device, thereby needle shaft keeps stable contacting to make connector obtain lower and stable resistance with stack shell.
For achieving the above object, the utility model provides a kind of connector pin shaft device, and it comprises:
Pipe in one, its interior end is fixed a spring, and pipe provides a space for the object of being located in it in this;
One needle shaft, it is located in the described interior pipe and with spring and is connected, this needle shaft is done motion straight in the pipe in described under the effect of external force, and an end of this needle shaft is equally spaced to be provided with some contacts, it is located at described spring housing wherein, this contact contacts with described interior pipe, thereby reduces the resistance of connector.
Especially, an end of described each contact periphery is equipped with a projection, and this projection makes described shell fragment and interior pipe even contact.
Connector pin shaft device provided by the utility model, thus needle shaft keeps stable contacting to make connector obtain lower and stable resistance with stack shell.

Fig. 1 illustrates the overall structure schematic diagram into the utility model connector pin shaft device.
Fig. 2 illustrates the decomposition texture schematic diagram into the utility model connector pin shaft device.
Fig. 3 illustrates the plane analysis structural representation into the utility model connector pin shaft device.
[embodiment]
The utility model provides a kind of connector pin shaft device, analyze shown in the structural representation according to the overall structure schematic diagram of Fig. 1 the utility model connector pin shaft device, the decomposition texture schematic diagram of Fig. 2 the utility model connector pin shaft device, the plane of Fig. 3 the utility model connector pin shaft device, this connector pin shaft device comprises:
One needle shaft 3, it is located in the described interior pipe 1 and with spring 2 and is connected, this needle shaft 3 is done straight motion can managing under the effect of external force in 1 in described, and an end of this needle shaft 3 is equally spaced to be provided with some contacts 4, it is set in described spring 2 wherein, and in this case preferred embodiment, described contact 4 quantity are 4, this contact 4 contacts with described interior pipe 1, thereby reduces the resistance of connector;
In this case preferred embodiment, described each contact 4 peripheral end are equipped with a projection 5, when described projection 5 with described in pipe 1 when contacting, described contact 4 produces certain profile bullet and becomes under the effect of projection 5, under the effect that this profile bullet becomes, described contact 4 produces the inside thrust of pipe 1 direction, under the effect of this thrust described projection 5 with described in pipe 1 even contact, thereby make uniform, stable resistance of described connector acquisition.
Connector pin shaft device provided by the utility model, thus needle shaft 3 keeps stable contacting to make connector obtain lower and stable resistance with interior pipe 1.
