Description
Technical field
The utility model relates to plugs and sockets fields, and in particular to a kind of 13pin trailer male plug.
Background technique
In routine use trailer, can using trailer connector male plug and mother socket be electrically connected so that vehicle in
Moved backward, left/right rotation or brake when, corresponding back-up lamp, left/right rotation car light, brake light can be lighted to do the effect warned, be dragged
Vehicle male plug, mother socket model multiplicity, have 7pin, 9pin, 13pin etc., trailer male plug is according to function difference, the terminal of installation
Number is different, in the terminal of male plug and shell installation process, needs to be mounted on terminal with terminal base or multiple components
On shell, 1 is usually had the disadvantage that, using terminal base mounting terminal, and install on the shell, common structure is easy to make
At reversed installation, the phenomenon that dislocation is generated, once reversed installation, can only scrap insulation crust, carries out shakedown, terminal base weight
New installation, wastes material, and client's use is restricted；2, terminal is installed on the shell by several components, process is more, installation
It is cumbersome, also do not utilize client to use.
Utility model content
Aiming at the shortcomings in the prior art, the utility model provides a kind of 13pin trailer male plug, by terminal base with
The ingehious design of connection structure between insulation crust, not only makes male plug inner connecting way simply firm, but also can also play
Foolproof function can prevent from reversely installing, will not generate inconsistent phenomenon.
The utility model is achieved through the following technical solutions: a kind of 13pin trailer male plug, including matched with mother socket
Insulation crust, terminal base, nut, line card, terminal, it is described in terminal is mounted on by described insulation crust one end by terminal base
The insulation crust other end is sequentially installed with line card, washer and nut, and for fixing core wire, the insulation crust inner wall is equipped with non-
It is symmetrical arranged and two pairs of boss structures not of uniform size, the terminal base outer wall is used to lock boss structure with being arranged with two pairs
Locking device in a certain range.By asymmetric setting being arranged and two pairs of boss structures not of uniform size and matched
Locking mechanism, so that it may which the phenomenon that reaching prevents from reversely installing, and prevents arranged in dislocation plays the role of fool proof.
Preferably, the boss structure includes two salient points, and the locking device includes buckle structure, stopping step, institute
Buckle structure is stated as circumferential convex-segment, and its head is in isosceles trapezoid, the boss structure by rotation may be stuck in buckle structure with
Between stopping step.Such structure design, when 13pin trailer male plug is installed, after terminal base is packed into insulation crust,
It rotates clockwise, when a pair of of buckle structure and stopping step block corresponding boss structure, another pair buckle structure and stop platform
Rank can block another corresponding boss structure, and terminal base can not exit counterclockwise at this time, and maintain a relatively stable state (factory
State)；When 13pin trailer mother socket and use of 13pin trailer male plug to it is slotting when, apply certain torsion, terminal base continuation
It rotates clockwise, a pair of of buckle structure and stopping step skip boss structure, and another pair buckle structure and stopping step are skipped pair
Another boss structure answered.When 13pin trailer mother socket needs to extract, terminal base is rotated counterclockwise, and applies certain torsion
Power, a pair of of buckle structure and stopping step reversely skip corresponding boss structure, and another pair buckle structure and stopping step are reversed
Corresponding boss structure is skipped, relatively steady state (factory state) originally is returned to.
Preferably, described insulation crust one end outer wall is equipped with the arc circumferential slot for engaging mother socket, and the other end is equipped with
Thread segment matched with nut.
Preferably, the terminal base bottom surface it is corresponding with also stamp has core wire to install cue mark at jack, play peace
It fills the effect of prompt, prevent from mixing up the installation site of core wire.
Compared with prior art, the utility model has the following beneficial effects: overcoming existing in the presence of reversed installation, generation
The phenomenon that dislocation and lead to waste of material and since component leads to disadvantage erroneous for installation more, by terminal base and shell it
Between connection structure ingehious design, not only make male plug inner connecting way simply firm, but also foolproof function can also be played, can
It prevents from reversely installing, inconsistent phenomenon will not be generated.

Specific embodiment
With reference to the accompanying drawing with specific embodiment, the utility model is described further.
As shown in Fig. 1~8, a kind of 13pin trailer male plug, including with the matched insulation crust 1 of mother socket, terminal base 2,
Nut 3, line card 4, terminal 6, in terminal is mounted on by 1 one end of insulation crust by terminal base 2,1 other end of insulation crust is successively
Line card 4, washer 5 and nut 3 are installed, for fixing core wire, 1 inner wall of insulation crust is equipped with asymmetric setting and not of uniform size
The first boss structure 101 of cause, second boss structure 102(are as shown in Figure 3), boss structure includes two salient points (such as Fig. 4 institute
Show), 2 outer wall of terminal base is used to lock the locking device of boss structure in a certain range with being arranged with two pairs.Locking device packet
Include the first buckle structure 201, corresponding first stopping step 202 and the second buckle structure 203, corresponding second stopping step
204, buckle structure is circumferential convex-segment, and its head is in isosceles trapezoid, when 13pin trailer male plug is installed, terminal base 2
After being packed into insulation crust 1, rotate clockwise, the first buckle structure 201 and the first stopping step 202 block first boss structure
When 101, the second buckle structure 203 and the second stopping step 204 can block second boss structure 102, and terminal base 2 can not be inverse at this time
Hour hands exit, and maintain a relatively stable state (factory state)；When 13pin trailer mother socket and 13pin trailer male plug use
To it is slotting when, apply certain torsion, terminal base 2 continues to rotate clockwise, the first buckle structure 201 and the first stopping step 202
First boss structure 101 is skipped, the second buckle structure 203 and the second stopping step 204 skip second boss structure 102.When
When 13pin trailer mother socket needs to extract, terminal base 2 is rotated counterclockwise, and applies certain torsion, 201 He of the first buckle structure
First stopping step 202 reversely skips first boss structure 101, and the second buckle structure 203 and the second stopping step 204 are reversely jumped
Cross second boss structure 102.Return to relatively steady state (factory state) originally, connection side inside 13pin trailer male plug
Formula is simply firm, and can also play foolproof function, can prevent from reversely installing, will not generate inconsistent phenomenon.In addition insulation crust 1
One end outer wall is equipped with the arc circumferential slot 103 for engaging trailer mother socket, and the other end is equipped with thread segment matched with nut 3
104.Also stamp has core wire to install cue mark 205 at 2 bottom surface of terminal base correspondence and jack, plays the work of installation suggestion
With, prevent from mixing up the installation site of core wire.
The protection scope of the utility model includes but is not limited to embodiment of above, and the protection scope of the utility model is to weigh
Subject to sharp claim, replacement, deformation, the improvement that those skilled in the art that any pair of this technology is made is readily apparent that are each fallen within
The protection scope of the utility model.
