A kind of probe-type electric connector
The utility model belongs to technical field of electric connectors, is specifically related to a kind of probe-type electric connector.
The electric connector of prior art, may produce the defect of instant cut-off, makes the supply of electric power of external device (ED) unstable, uses inconvenience.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of probe-type electric connector, to solve the technical problem.
For solveing the technical problem, embodiment of the present utility model provides a kind of probe-type electric connector, comprise a shell, a probe and a spring, described probe is an electric conductor, by shell institute accommodating and by spring supporting, stressed rear support its produce axial motion; Described probe shaft to two corresponding end there is a contact site and a conducting portion respectively, described contact site local is exposed to shell, and described conducting portion is connected with a wire and the also conducting that is connected with the circuit of external device (ED).
The inside of described shell has a room, and two corresponding end of its axis have to bore a hole with first of described room intercommunication bores a hole with second.
Described probe has a body, among the room being located at shell, described contact site is by the first perforation and local is exposed to outside shell, described contact site and body junction, be provided with the baffle plate that the inwall direction towards shell is protruded, the activity in described baffle plate Restricted Contact portion makes to avoid probe to deviate from from the first perforation, and corresponding second perforation of described conducting portion, bores a hole by described second when described probe start; Described spring is set in outside the body of probe, and its one end is resisted against baffle plate, and opposite end is resisted against the bottom of room.
The wide perseverance in footpath of described spring is greater than the second perforation.
The beneficial effect of described technical scheme of the present utility model is as follows:
Supply of electric power of the present utility model is stablized and can not be interrupted, and has practicality.
Accompanying drawing explanation
Fig. 1 is stereo appearance figure of the present utility model.
Fig. 2 is sectional structure chart of the present utility model.
Fig. 3 is that use of the present utility model is with reference to figure mono-.
Fig. 4 is that use of the present utility model is with reference to figure bis-.
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As depicted in figs. 1 and 2, the utility model provides a kind of probe-type electric connector, comprises probe 2, shell 3 and a spring 4, the inside of described shell 3 has a room 30 can accommodating probe 2, and two corresponding end of described shell 3 axis have mutually with described room 30 through first bores a hole and 31 and second bore a hole 32, described probe 2 is an electric conductor, it has a body 20, among the room 30 being located at shell 3, two corresponding end of described body 20 axis have contact site 21 and a conducting portion 22 respectively, described contact site 21 is by the first perforation 31 and local is exposed to outside shell 3, contact site 21 and body 20 junction, be provided with the baffle plate 23 that inwall 33 direction towards shell 3 is protruded, described baffle plate can the activity in Restricted Contact portion 21 make to avoid probe 2 to deviate from from the first perforation 31, corresponding second perforation 32 of described conducting portion 22, can by described second perforation 32 when probe 2 start, described spring 4 is set in outside the body 20 of probe 2, and its one end is resisted against baffle plate 23, and opposite end is resisted against the bottom of room 30, and the wide perseverance in footpath of described spring 4 is greater than the second perforation 32, supports the start of described probe 2 axis in order to supporting probe 2.
Using state as shown in Figure 3 and Figure 4, described shell 3 is positioned on a holder 5, be connected by a wire 7 between the conducting portion 22 of probe 2 and the circuit board 6 of external device (ED), when battery 8 crimps towards the contact site 21 of probe 2, probe 2 because of stressed and by baffle plate 23 apply pressure to spring 4 produce distortion, the spring 4 of distortion produces a reaction force makes the contact site 21 of probe 2 can contact with battery 8, makes the electric current of battery 8 directly can flow to circuit board 6 for external device (ED) by probe 2.
The electric current supplied due to battery 8 is shorter than spring 4 by the path of probe 2, and spring 4 does not communicate with the circuit of circuit board 6, so the place circulation that the electric current of major part can select impedance low; Therefore most electric current can flow directly into circuit board 6 by probe 2, and the supply of electric power can more be stablized and can not interrupt, and has practicality.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
