Embodiment
In order that technological means, creation characteristic, reached purpose that the utility model is realized more understand and are easy to acting on
Understand, the utility model is further elaborated with reference to the accompanying drawings and detailed description：
Shown in reference picture 1-4, the utility model proposes a kind of direct insertion combination transformer, including transformer body 10,
The side lower end of the transformer body 10 is provided with secondary wiring terminals 11, and the secondary wiring terminals 11 are disposed as being used for
The jack form inserted for the banana plug of secondary cable, these jack type terminals pour with transformer body 10 to be integrated；And
And transformer body 10 is additionally provided with plug clamping device 12 beside jack type terminal, the plug clamping device 12 wraps
Include：
A pair of L-shaped flexure strip 121, it is distributed in the both sides of jack type terminal and arranged in holding claw formula, the pair of L-shaped
Flexure strip 121 offers semicircular indentations 122 on respective kink, inside and outside the semicircular indentations 122
It is rounded down 123；After the current-carrying part 21 of banana plug 20 inserts secondary wiring terminals 11, the pair of L-shaped flexure strip 121
Bending place can just be stuck in the tail end both sides of banana plug body part 22.
In such scheme, the utility model made secondary wiring terminals 11 into jack shape on transformer body 10 before this
Formula, so as to allow secondary cable to be inserted directly therein the connection that can be completed with transformer by banana plug 20, installation is fast
Victory is convenient；And in order to prevent banana plug 20 from coming off, it is additionally provided with easy plug clamping device 12.The plug clamping device 12
Mainly it is made up of a pair of L-shaped flexure strips 121 in holding claw formula, banana plug 20 is carried out in plug orientation by L-shaped shell fragment
Clamp.Moreover, it is contemplated that most of 20 each corners of banana plug are cambered design till now, therefore for the ease of banana plug
20 pull and push operation from this two semicircular indentations 122 to flexure strip, and this has also carried out chamfered (i.e. half to flexure strip
Inside and outside circumferential notch 122).With reference to shown in Fig. 2 or Fig. 4, when the semicircular indentations 122 of current-carrying part 21 of banana plug 20
When, flexure strip, which will not be extruded, will not deform.And when the body part 22 of banana plug 20 passes through semicircular indentations 122
When, because diameter is more than the distance between two semicircular indentations 122, therefore flexure strip can be extruded makes two flexure strips to both sides
Bending, until the body part 22 of banana plug 20 is completely disposed in the L-shaped space of L-shaped flexure strip 121, the ability of flexure strip 121
Recover.
It is inadequate easily to there is elastic force after a long time use in view of L-shaped flexure strip, leads to not to banana plug 20
The phenomenon being clamped occurs, and in the utility model, is entered between L-shaped flexure strip and transformer body 10 using dismountable mode
Row connection.Specially：
Shown in reference picture 2-4, the pair of L-shaped flexure strip 121 is distributed in jack type terminal by a pair of fixed blocks 13
Both sides, and be removably attached with fixed block 13, the pair of fixed block 13 is fixed with transformer body 10
Set.I.e. by being indirectly connected between fixed block 13 and transformer body 10.In the program, L-shaped flexure strip to be realized with
Being detachably connected between fixed block 13, implementation has many kinds.Such as it is connected by screw bolts, buckle-type connection, riveted connection
It is feasible.But the utility model has provided a kind of preferred embodiment, the embodiment can allow the replacing of L-shaped flexure strip
It is more convenient, and have enough stability.Embodiment is as follows：
Such as Fig. 2-3, offer U-lag 131 on the pair of fixed block 13, two U-lags 131 backwards to setting, and
Opened wide in outer end；Flexible ball 133, the fix bar are arranged by fix bar 132 in each U-lag 131
132 perpendicular to the bottom of U-lag 131；
Wherein, the tail end of the pair of L-shaped flexure strip 121 offers perforation (not shown), and is squeezed respectively by perforation
Press the ball 133 in two U-lags 131 and L-shaped flexure strip 121 is lock onto on fixed block 13.
It was found from the program, L-shaped flexure strip 121 is to be locked at by ball 133 on fixed block 13.Specifically, when
When needing to load L-shaped flexure strip 121, directly the perforation of L-shaped flexure strip 121 is aligned with ball 133, then with hand by L-shaped
Flexure strip 121 can be (because ball 133 can be by perforation hole wall during press-in out of sidepiece press-in U-lag 131
Extruding deforms), and after perforation passes completely through ball 133, ball 133 returns to the original form again, so as to just by L
Shape flexure strip 121 is lock onto on fixed block 13.Similarly, when needing to change L-shaped flexure strip 121, ball 133 only need to be pinned,
Then allow the perforation of L-shaped flexure strip 121 to extrude ball 133 L-shaped flexure strip 121 can be departed from from U-lag 131.
Wherein in the case of one kind, U-lag 131 can be processed relatively deeply, allow ball 133 to be completely in groove, so
When user loads L-shaped flexure strip 121, the rear wall of U-lag 131 can to L-shaped flexure strip 121 stretch into carry out it is spacing, from
And allow the perforation of L-shaped flexure strip 121 can be with the rapid alignment of ball 133.Because semicircular indentations 122 are located at L-shaped flexure strip
121 front end kink, therefore the locking of the rear end of L-shaped flexure strip 121 has no effect on the bend by pressure of the front end of L-shaped flexure strip 121
Deformation.
It is that arranged for interval has two groups of balls 133 in U-lag 131 as further embodiment of the present utility model,
This two groups of balls, 133 rectangular arrangement, understood with reference to Fig. 2-4.Two groups of balls 133 are set to increase to L-shaped flexure strip
121 coupling mechanism force, and be that length based on banana plug 20 considers that set (banana plug 20 is grown, L-shaped flexure strip 121
Required length is just grown, it is therefore desirable to the rear end locking of L-shaped flexure strip 121 is completely secured).
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
