Detailed description of the invention
Cable binding post and power cable to this utility model embodiment are described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, according to embodiment of the present utility model, cable binding post includes threading portion 10 and connects Meeting portion 20, threading portion 10 is provided with cable receiving hole 11, and cable receiving hole 11 runs through the one end in threading portion 10, and forms opening 12, threading portion 10 is provided with the crimping mark structure 13 of mark crimping position.
This cable binding post accommodates cable by threading portion 10, and connecting portion 20 is for being connected with other conductors.Cable Receiving hole 11 is used for accommodating cable, and after by crimping process, the inwall of cable receiving hole 11 and cable are fully contacted realization even Connect.Opening 12 penetrates in cable receiving hole 11 for cable.Crimping mark structure 13 is used for identifying crimping position, it is ensured that carrying out electricity During the crimping of cable and binding post, crimping position is accurate, and crimping uniformly, and then guarantees to crimp effect, it is to avoid due to operative employee The crimping that people's operational error causes is uneven, conductor and the problem such as binding post is insufficient contact, contact resistance is big.
In the present embodiment, cable binding post can be DT type binding post or DTM type binding post.
In the present embodiment, crimping mark structure 13 includes the impression being arranged on the outer surface in threading portion 10.Impression can Identifying crimping position well, processing is simple simultaneously.Impression is the groove that a degree of depth is less, and it has certain positioning action, makes Operator can make crimping tool coordinate with threading portion 10 more easily, and crimping operation is convenient.
Specifically, the surface uniform Design impression in threading portion 10 (indentation width 9mm, or according to crimping tool pressing mold width Degree value, such as 7mm or 12mm or other), with clear and definite crimping position, facilitate on-site construction operations.
Crimping mark structure 13 is at least two, and at least two crimping mark structure 13 is along the threading of cable receiving hole 11 Direction is spaced setting successively.Indent spacers determines according to pressing mold width and impression quantity, ensureing electrically and mechanically before performance Putting, impression can be three roads, it is also possible to for other numerals.
See Fig. 1 and Fig. 2, Fig. 4 and Fig. 5, be provided with guiding chamfering 14 at the opening 12 of cable receiving hole 11, hold along cable The inlet wire direction of receiving bore 11, the cross-sectional area of opening 12 is gradually reduced.So can form a guide surface, make threading more square Just, and it can be avoided that in threading process part copper wire leak situation about wearing, reduce operation easier, can while lifting operation efficiency Improve threading quality.
In the present embodiment, guiding chamfering 14 is 45 ° of chamferings.This guiding chamfering 14 is easy to processing and can be reduced and be processed into This, and crudy can be improved.Certainly, in other embodiments, can be to use the guiding chamfering 14 of other forms, such as, Guide line is the guiding chamfering etc. of camber line.
Preferably, in order to reduce threading difficulty further, it is to avoid leakage is worn, the aperture of cable receiving hole 11 is more than or equal to needing The diameter of threading cable.So guarantee that cable receiving hole 11 can accommodate whole cable, and then reduce threading difficulty.Certainly, for Guarantee the effective contact after crimping, be advisable with the equal diameters of threading cable with the aperture of cable receiving hole 11.
Specifically, in the present embodiment, the diameter of cable receiving hole 11 is led according to " GB/T 3596-2008 " five class copper core Body largest conductor diameter determines, to guarantee to be easier to cable conductor and binding post threading.Such as 1*240mm2Five class conductors are Big external diameter 24mm, the internal diameter of cable receiving hole 11 is also 24mm.It is easier to cable conductor and binding post threading.
As shown in Figure 6, the one end away from opening 12 in threading portion 10 is provided with observation port 15, and observation port 15 accommodates with cable Hole 11 connects.Threading progress can be observed, to determine whether cable threading arrives line nose terminal location, also by observation port 15 The discharge of binding post inner air during cable crimps can be observed.Meanwhile, observation port 15 may be used for discharging cable appearance Moisture in receiving bore 11.
Observation port 15 can be square, it is also possible to be other shapes.
It should be noted that observation port 15 is suitably arranged on DT type binding post.
As shown in Figure 3 and Figure 6, connecting portion 20 is one-body molded with threading portion 10, and be arranged on threading portion 10 away from opening On one end of 12.Connecting portion 20 is used for connecting other conductors.Connecting portion 20 is provided with fixed installation hole 21, fixedly mounts hole 21 may be used for wearing other fixtures, to be fixed with other conductors by connecting portion 20.In the present embodiment, connecting portion 20 is flat Flat lamellar.
Identify the parameter etc. of the cable of binding post kind and connection for the ease of operator, connecting portion 20 also sets up There is marker bit 22.Marker bit 22 may be used for placing the nameplate with information, paster etc..
According to another aspect of the present utility model, it is provided that a kind of power cable, it includes cable main and is arranged on cable The cable binding post of at least one end of main body, cable binding post is above-mentioned cable binding post.
The power cable using this cable binding post to carry out wiring crimps effective, it can be ensured that the load of power cable Stream ability.
Cable binding post of the present utility model has the effect that
DT type and DTM type binding post connect according to " GB/T 3596-2008 " five class copper core conductor largest conductor diameter design Line terminals internal diameter, it is ensured that the convenience of cable threading, solves on-the-spot threading difficulty, the problem that part copper core conductor leaks outside.
The opening part of cable receiving hole arranges guiding chamfering, relatively increases the internal diameter of cable receiving hole opening part, is more conducive to Cable threading.
The surface uniform Design impression in threading portion, specifies crimping position, facilitates on-site construction operations, solves because constructing The crimping that peopleware is uneven to be caused is lack of standardization thus problem that occur crimp quality is bad.
DT type binding post design observation port, on the one hand conveniently checks whether cable threading arrives tip position, and two is to use In the humid air within the reserved location of discharge DT type binding post top, it is ensured that the crimp quality of binding post.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in change Or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described power The protection domain that profit requires is as the criterion.
