Description
Technical field
The utility model relates to a kind of electric connectors.
Background technique
Existing electric automobile high-voltage connector can be divided into plug-in type and two kinds of bolt connection type, the former is easy to operate but in automobile
Life cycle management reliability is relatively difficult to guarantee under operating condition, higher cost；The latter is at low cost, but if operator is not by bolt pressure
When tightly or bolt thread cooperation exception leads to malcompression but normal torque, it will lead to contact area and become smaller, contact resistance increases,
There are ablation risks for fever.As shown in Figure 1, lead wiring terminal 1 and connector terminal 2 are spirally connected fixation by bolt 3.But
It is in malcompression or in the case where automobilism is more jolted, it may appear that lead wire terminal as shown in Figure 1
Connection between son 1 and connector terminal 2 loosens, and leads to the generation of various risks or danger.
Utility model content
The purpose of this utility model is to provide a kind of electric connectors, connect for solving electric connector in the prior art
Lead to the problem of various risks or danger when touching bad.
To achieve the above object, the utility model proposes a kind of electric connector, including shell, enclosure interior setting conducting wire is connect
Line terminals, connector terminal and connection bolt, the connection bolt are fixedly connected with the lead wiring terminal and connector
Connecting terminal；The connector terminal has the upper surface for being in contact with lead wiring terminal；On the upper surface
Through-hole is offered, the drive rod of a microswitch is provided in the through-hole, the upper end of the drive rod is protruded on described
End face.
Microswitch is arranged in the utility model, by the state of microswitch and the state relation for connecting loosening, thus
The information loosened can be connected with timely learning, so as to and alarm, avoid risk and dangerous generation.
In order to obtain the information of loosening as early as possible, one far from lead wiring terminal on the upper surface is arranged in the through-hole
Side.
Sensitiveer in order to act, the drive rod is elastic probe.
In order to save enclosure interior space, the main part of the microswitch is fixed on the hull outside.
Detailed description of the invention
Fig. 1 is the type electric connector structure figure that is spirally connected of the prior art；
Fig. 2 is a kind of structural schematic diagram of embodiment provided by the utility model；
Fig. 3 is hull outside structure chart；
In figure: 1 be lead wiring terminal, 2 be connector terminal, 3 be connection bolt；
11 it is lead wiring terminal, 12 be connector terminal, 13 be conducting wire, 14 be shell, 110 is lead wire terminal
The mounting hole of son, 120 be the mounting hole of connector terminal, 121 be through-hole, 122 be drive rod；141 for mounting bracket,
142 be the main part of microswitch.
Specific embodiment
As shown in Fig. 2, the electric connector of the present embodiment includes shell 14, connector is fixed on the bottom surface inside shell 14
Connecting terminal 12, conducting wire 13 are penetrated from housing sidewall, and the lead wiring terminal 11 of end is placed on connector terminal 12
Upper surface on, mounting hole 110, the connector wiring of lead wiring terminal are passed through by screw or bolt (being not drawn into figure)
Lead wiring terminal 11 is fixedly connected by the mounting hole 120 of terminal with connector terminal 12.
The electric connector is additionally provided with a microswitch, and the main part 142 of the microswitch is solid by mounting bracket 141
Surely it is assemblied in 14 outside of shell, as shown in Figure 3.The main part of microswitch includes driver portion, quick-acting mechanism portion, contact portion
And portion of terminal；Driver portion is used to that internal structure will to be passed to from external power or stroke；Quick-acting mechanism portion is using conductive bullet
Spring etc. is for executing quick-action movement；Contact portion is used to open or closes internal circuit；Portion of terminal with external circuit for connecting.It is main
It include a drive rod 122 in connection actuator portion except body portion.
The upper surface of connector terminal 12 is additionally provided with a through-hole 121, and it is logical that the drive rod 122 of microswitch protrudes into this
In hole 121, and the upper surface of the end protrusion connector terminal of drive rod 122.Drive rod is preferably elastic component, such as bullet
Property probe.
Working principle is:
Since the drive rod 122 of microswitch and the driver portion of microswitch link together, work as terminating wire
After terminal 11 is fixedly connected with connector terminal 12, lead wiring terminal 11 can press down on drive rod 122, according to normal
Closed form microswitch, microswitch interior contacts are not closed at this time.If in use, there is 11 He of lead wiring terminal
Loosening or disengagement between connector terminal 12, then microswitch restores normally closed, issues on-off model from portion of terminal.
Similarly using open type microswitch, it repeats no more.
Output on-off model can access high-pressure-loop interlock detection circuit, the switching value letter as loop interlocking detection
Number；It can also access in an electrical detecting tool, the inspection that whether connector is properly installed when as detection installation
Survey foundation.About loop interlock detection circuit, detecting tool etc., the prior art is belonged to, therefore is not illustrated.
Since the left end of connector terminal 12 is close to one end of conducting wire 13, lead wiring terminal 11, right end is remote
From conducting wire 13, one end of lead wiring terminal 11, when loosening, lead wiring terminal 11 would generally be stuck up from right end first
It rises, it is therefore preferable that on the upper surface of connector terminal 12, the above-mentioned through-hole of the arrangement of one end far from lead wiring terminal 11
121, to obtain the information of loosening as early as possible.Alternatively, it is also possible to select through-hole 121 according to the stress situation of lead wiring terminal 11
Position with the stress of equalizing contactor connecting terminal 11.
In the present embodiment, a through-hole is arranged；As other embodiments, can also be arranged in upper surface multiple logical
Hole, and multiple microswitches are arranged accordingly, generates multiple signals for using, and for Redundancy Design, mutual tests
Card or the degree occurred for judging loosening (completely disengaged or part disengages).
In above embodiments, the main part 142 of microswitch is to save shell outside shell and including drive rod
Space inside 14.It is in order to facilitate the installation of that connector terminal 12, which is placed on 14 bottom surface of shell,.
