Embodiment
Fig. 1 is the assembling view that the utility model is tightly locked the connector preferred embodiment, this tight lock connector, comprise connector (1A, 1B) and linking arm (3), wherein said connector (1A, 1B) formed by inner sleeve (1) and outer cap (2), inner sleeve (1) and outer cap (2) cable that is connected, the other end of inner sleeve (1) and linking arm (3) join, at least be fixed with a connector (1A on the linking arm (3), 1B), present embodiment has been fixed two connector (1A, 1B), also be provided with fixed handle (4) on the linking arm, have one on the fixed handle (4) at least for the through hole (41) that is connected with electric power electrical apparatus.Connector of this tight lock connector can be processed into one or more according to actual needs, no matter quantity, its form, principle are identical, and the large I of model differs.
Such as Fig. 1,4, fixed handle and linking arm angular range are preferably 90 ° between 0 °-180 °.Fixed handle (4) can also can be in a side of linking arm (3) in the centre of linking arm (3), and present embodiment is located at a side of linking arm (3).
As shown in Figure 2, inner sleeve (1) is tubulose, an end opening (10), and opening (10) inwall has the fine thread (not shown), increasing friction force, fastening grip are installed bearing tension when being connected thereby also strengthened this connector and cable; The inner sleeve appearance has inner sleeve first step (11), inner sleeve slope (12), inner sleeve second step (13); Cylindrical at the inner sleeve other end is provided with screw thread, i.e. interior external threading (14); Opening (10) has plural at least machinery seam (15) to the interior jacket wall of interior external threading (14), the systolic pressure of jacket wall in increasing, increase simultaneously the contact area of this connector and cable, namely better execution concurrence has been waved the science of expansion bolt principle.
Connector of this tight lock connector can be processed into one or more according to actual needs, no matter quantity, its form, principle are identical, and the large I of model differs.
Outer cap (2) main with inner sleeve (1) on the use of connector coupling, namely the large palpulus of the quantity of outer cap and model and connector are consistent.Structure and the characteristics of outer cap (2): outer cap (2) is the bucket shape tubulose, one end is polygonal nut (25), its internal structure comprises: outer cap internal thread (24), outer cap first step (23), outer cap second step (22), outer cap the 3rd step (21).Three interior steps (23,22,21) of outer cap respectively with two steps (11,13) Matching installation of inner sleeve, be multi-stage stairs and tightly lock principle.The Main Function of outer cap the 3rd step (21) is: guaranteed that the cable part outside opening (10) that contacts with this joint can not produce loose phenomenon.Multi-stage stairs locks tightly that principle makes the contact area of whole product and cable larger, fastening grip is stronger, mechanical stability is better, when causing electric current to pass through this product with cable, temperature rise is lower, resistance is less, current stability is better, has namely reduced the electric energy loss in the power equipment running.
The principle of expansion bolt is adopted in this tight lock connector global design, has added simultaneously multi-stage stairs and tightly lock principle on the coupling of inner sleeve (1) and outer cap (2).The installation method of itself and cable: cable is passed the tubular inner wall of putting into inner sleeve (1) behind the outer cap (2), then with common wrench outer cap (2) and inner sleeve (1) are tightened and get final product.
