Specific embodiment

The preferred forms of the utility model are illustrated with reference to the accompanying drawing, herein the axial direction Identical as the length direction of electric power connector, the radial direction refers to the ring perpendicular to the axial direction or length direction To.The tail end is that one end of connection cables, is front end with tail end opposite direction.

If Fig. 1 to Fig. 7 shows a kind of electric power connector of the most preferred embodiment of the utility model, institute referring to Fig. 1 and Fig. 2 Show, a kind of electric power connector of most preferred embodiment according to the present utility model, to cable (because be not the art of this patent side The focus of case, is not shown in the figure) connection, including connector plug 01, circuit substrate 02, metal shell 03 and insulation internal model 04.The insulation internal model 04 is made of thermosetting plastics, forms scheduled shape after cooling and solidifying again after heating melting, plays Effect is sealed and fixed, specifically, after the connector plug 01, circuit substrate 02 and metal shell 03 fit together The internal model glue for filling the insulation of molten forms the insulation internal model 04 of insulation, more specifically, described after encapsulated rear cooling and solidifying Connector plug 01 is installed on the circuit substrate 02 (referring to Fig. 5), and the metal shell 03 is coated on the circuit substrate 02 periphery simultaneously with the tail portion of the connector plug 01 with buckle fixed (referring to Fig. 6), the insulation internal model 04 is by the gold (referring to Fig. 7) together with category shell 03, the circuit substrate 02 are encapsulated with the tail portion of the connector plug 01, by insulation The encapsulated fixation of mould 04, increases the fold resistance of structure.

Referring again to shown in Fig. 1 and Fig. 2, in the present embodiment, it is also equipped with insulation external mold 05, in molding mode and insulation Mould 04 is similar, but insulate that the material is soft and molding thickness is thicker for external mold, and the insulation external mold 05 is by the insulation internal model 04, the tail end of metal shell 03 and the coupling part of cable are encapsulated together, so that electric power connector be made also to have when waving Good disturbance rejection.

Shown in Figure 3, the connector plug 01 includes metal main casing 011, insulation rubber shell 012 and conductive terminal 013, The metal main casing 011 and conductive terminal 013 are made through the stamping process by materials such as metal materials such as stainless steel, copper alloy At the conductive terminal 013 is installed in a row at a certain distance in the separate slot 0124 in the insulation rubber shell 012, the gold Owner's shell 011 is set in the outside of the insulation rubber shell 012.

With reference to Fig. 4, and as shown in connection with fig. 3, illustrate in further detail, the insulation rubber shell 012 is by engineering resin such as PA Material etc. is made up of injection molding process, and the tail end of the insulation rubber shell 012 is equipped with the groove filled by the insulation internal model 04 0121, in the present embodiment, the groove 0121 is recessed along the annular of the outer surface of the insulation rubber shell 012 radially extended Slot, it is preferable that be the intensity of reinforced insulation rubber shell 012, the centre of the annular groove has additional bridge-linking part 0122, as a result, by institute It states annular groove 0121 and is separated into two part 0121a and 0121b (as shown in Figure 4), in this way while increasing structural strength, Also avoid during profiled insulation internal model 04 melting shape insulate internal model glue object in annular groove 0121 because of flow distance It is too long and filling insufficient leads to insatiable hunger glue problem.

Preferably, with continued reference to Fig. 4, and as shown in connection with fig. 3, the upper and lower surfaces of the insulation rubber shell 012 are at least within One surface is equipped with card convex portion 0123, and in the present embodiment, card convex portion 0123 is set on the side of bridge-linking part 0122, and quantity is Two, and the intermediate symmetry about bridge-linking part, the metal main casing 011 is equipped with mutually to be buckled with the card convex portion 0123 The width of card slot 0111, the card slot 0111 is greater than the card convex portion 0123 (referring to Fig. 3), in this way, having more the part of width Card slot space can fill insulation internal model 04, and insulation internal model 04 is made to be interlocked with metal main casing 011, and then enhancing structure Survivability.

Further, to further increase insulation internal model 04 to the interlocking effect of structure, by scheduled conductive terminal 013 is installed on the corresponding separate slot 0124 of the insulation rubber shell 012, is not installed with the conductive terminal 013 to therein Separate slot 0124 carries out perforation process, penetrates through those separate slots 0124 by through hole 0121h and the annular groove 0121, so as to These spaces of inflow for the internal model 04 that insulate, and then increase the anti-destructive of structure.

In the present embodiment, as shown in fig. 6, in order to which more easily enhancing metal shell 03 and the connection of connector head 01 are strong Degree is provided with double branch clamping parts 031, two branch 031a, 031b opposite direction arrangement ground card in the side of the metal shell 03 Due in the annular groove 0121 of connector head 01, effect is engaged for enhancing, described clamping part 031a, 031b are smooth arm Curved certain angle, which is rushed, by the direction of rear processing procedure towards annular groove 0121 forms bending arm.

With reference to the accompanying drawing, the assembling process of the electric power connector of the best embodiment of the utility model is described in detail:

Firstly, assembling metal main casing 011, insulation rubber shell 012 and conductive terminal 013 form connector plug 01, such as Fig. 3 institute Show；

Then, connector plug 01 made of previous step is installed on circuit substrate 02, passes through conductive terminal 013 The techniques soldering such as SMT is connected on circuit connection pad 02a, as shown in figure 5, then, cable (not shown) is installed on circuit On the corresponding link position of substrate.

After again, metal shell 03 is set in the component external that previous step is formed from rear, after assembling in place, is passed through Double branch clamping parts 031 punching of smooth arm is curved bending arm by jig, and clamping part 031 is made to be fastened in the annular groove 0121 It is interior, as shown in Figure 6.

Then, the splayed legs 032 of 03 tail end of metal shell are crimped and teamed cable is fixed.

After again, solidification is formed after injecting the insulation glue of melting on the outside of the tail end for the component that previous step is formed and cool down The insulation internal model 04 of shape afterwards, as shown in fig. 7, however, it is desirable to explanation, in this step, stabilizer blade 032 should be upper one It is closed after step process, is not practical so only showing state identical with previous step herein since cable is not shown Shape.

Finally, by the insulation external mold 05 after the encapsulated forming and hardening of tail end in the component external that previous step is formed, into And form the shape of electric power connector as shown in Figure 1.The cable in insulation 05 tail end of external mold is omitted in this Fig. 1, does not make Practical foundation only makees shape reference.

The above only lists the most preferred embodiment of the utility model, and the utility model implementation cannot be limited with this Range, any similar technical solution all should belong to disclosed content.
