Limiting section 11 on female plug terminal 1 is overlapped on the end of the fixed part side wall 312, so, can be up and down the two of longitudinal direction
The female plug terminal 1 is fixed on individual direction so that female plug terminal 1 will not in the first joint 3 up and down vibration.
On the outer wall of the female plug terminal 1 limit ribs 12 are vertically arranged with along the female plug terminal, it is described spacing
Rib 12 can be raised line (can also be groove), for being coordinated with the stopper slot 23 (or rib) on male plug terminal 5
(being described in detail below).
As viewed in figures 5-8, the 5 generally cylindrical structure of positioning sleeve, its inner chamber and the appearance and size of the male plug terminal 2
Match.It is provided with rib 21 (referring to Fig. 6) on the outer wall of the male plug terminal 2, the shape and structure of the rib 21 can be with
To be a variety of, in one embodiment, it is П shape structures, is provided with the respective inner walls of the positioning sleeve 5 and the rib
The corresponding groove 51 of 21 shapes, size, the male plug terminal 2 and positioning are realized by the cooperation of the rib 21 and groove 51
Assembling fool proof between set 5, realizes the accurate installation of male plug terminal 2.In a further embodiment, in the male plug terminal 2
Groove is provided that on outer wall, the rib corresponding with the groove is provided that in the respective inner walls of the positioning sleeve 5,
Identical function can be realized.Neck 22 is additionally provided with the outer wall of the male plug terminal 2, on the inwall of the positioning sleeve 5
The snap-in structure 52 with the shape of neck 22, matching size is provided with, referring to Fig. 8, the snap-in structure 52 includes being arranged on
Clamp 521 in the side wall of positioning sleeve 5, upper end (relative to the orientation shown in Fig. 8) and the positioning of the clamp 521
The side wall of set 5 is connected, and groove is provided between the side wall of other edges and the positioning sleeve 5, so, may be such that the card
Plate 521 has certain elasticity so that the male plug terminal 2 can be inserted smoothly in the positioning sleeve 5；The clamp 521
Bottom extends to the intracavitary of the positioning sleeve 5, facilitates the clamp 521 to be caught in the neck 22.In a preferred embodiment
In, the neck 22 is generally U-shaped.After the male plug terminal 2 is inserted into the positioning sleeve 5, the clamp of the snap-in structure 52
521 are caught in the neck 22, can prevent the male plug terminal 2 from being loosened in the positioning sleeve 5.
Joint connection 53 is additionally provided with the lower end of the positioning sleeve 5, the joint connection 53 is coupler construction,
The free end of the joint connection 53 forms the holding section 531 that oriented radial outside protrudes.In the lower end of the positioning sleeve 5
It is provided with one or more joint connection 53.The joint connection 53 is used to the positioning sleeve 5 being fixed to described the
On two joints 4.
As shown in figure 9, second joint 4 generally tubular construction, including terminal insertion portion 41, the terminal insertion portion
41 are located at one end of second joint 4, formed with through hole 411, the quantity and size of the through hole 411 and institute in its side wall
Quantity, the size for stating the holding section 531 of the joint connection 53 on positioning sleeve 5 are corresponding.When the positioning sleeve 5 is inserted into institute
When stating in the inner chamber of the terminal insertion portion 41 of the second joint 4, the holding section 531 is engaged in the through hole 411, to described fixed
Position set 5 is positioned relative to second joint 4.
In order to realize the connection fool proof between the joint 4 of positioning sleeve 5 and second, the joint 4 of positioning sleeve 5 and second
A part for the side wall of terminal insertion portion 41 is respectively formed as specific adapter structure, and the setting of the adapter structure can cause institute
State that the assembling orientation of the joint 4 of positioning sleeve 5 and second is more obvious, avoid the joint 4 of positioning sleeve 5 and second with the orientation of mistake
Installation, the adapter structure can be arcuate shape 54,42, as shown in Fig. 7,9, or other structures, such as section
For structures such as curved surfaces, bending plane.So, the positioning sleeve 5 is being inserted to the terminal insertion portion 41 of second joint 4
When, simply the insertion orientation of the positioning sleeve 5 can be determined, simplify assembling process.
As seen in figs. 5-6, the male plug terminal 2 on the wall coordinated with the female plug terminal 1 formed with stopper slot 23,
When female plug terminal 1 is inserted into the male plug terminal 2, the rib 12 and stopper slot 23 are coordinated, can be to the female plug end
The insertion of son 1 guides, while can avoid the contact pin loose contact in female plug terminal 1 and male plug terminal 2.
Preferably, the male plug terminal 2 for the female plug terminal 1 insertion end formed with chamfered section 24, it is described fall
Corner 24 can be clinoplain, or tilt cambered surface so that the inner chamber of the male plug terminal 2 is closer to the male plug end
Its radial dimension of end of son 2 is bigger, and so the insertion of the female plug terminal 1 can be oriented to, and avoids producing punching during assembling
Power is hit, avoids damaging terminal structure during assembling, the service life of terminal can be improved.
In the present invention, the positioning sleeve 5 equipped with male plug terminal 2 is inserted after the terminal insertion portion 41 of second joint 4,
The connection is inserted into one end where connecting portion 32 of the terminal insertion portion 41 of second joint 4 from first joint 3
In portion 32, the coupling between female plug terminal 1 and male plug terminal 2 is realized.Preferably, first joint 3 and second joint 4
On the corresponding sidewall sections of adapter structure 42 be also formed as adapter structure 33, equally, the adapter structure 33 can be arc
Shape shape, or other structures, such as section are the structures such as curved surface, bending plane.So, connect by described second
Fool proof effect can be realized during first the first joint 3 of 4 insertion, avoids inserting wrong court between terminal, simplifies terminal coupling process.
In the present invention, realize that terminal couples by the way that male plug terminal 2 and female plug terminal 1 are fitted into joint, can pass through
Assembling between joint couples to improve terminal, eliminates impulsive force caused by the blind dress of terminal, and by terminal and can connect
Structure between head and between joint and joint realizes assembling fool proof, can greatly simplify terminal coupling process, and can realize end
Accurate, firm coupling between son, improve terminal working condition, improve terminal service life.
