The shell comprises an upper cover and a lower cover which are movably buckled, thereby facilitating the assembly operation, being capable of enlarging the internal assembly space of the shell, and having simple structure and easy manufacture; the inner surfaces of the wire chases covering and clamping the lead are properly provided with the lug bosses or the sunk parts, therefore, during the assembly, when the lead is pressed, the outer peripheral face of an insulating layer is held in the sunk parts after being pressed by the lug bosses or deformed so as to limit the stretching and contraction of the lead, and the welding part of an internal lead cannot be influenced by external pulling, thereby maintaining the stability of the welding.

Description

The connector shell package assembly

Technical field:

The utility model relates to technical field of electric connectors, refers in particular to a kind of connector shell package assembly.

Background technology:

Existing electric connector is coated with an insulation crust usually, with welding position between covering lead and the terminal, and obtains good grip effect.In the prior art, insulation crust generally adopts injection molding to form or wave soldering forms, and there is assembling inconvenience in this structure, easily makes mistakes; The inner space is little, is unfavorable for wire bonds, and shell lacks the location to lead, occurs easily pullling and causes the welding position loosening or come off etc., thereby at existing shell mechanism, hold and wait to improve.

Summary of the invention:

The purpose of this utility model be to provide a kind of can the realization activity shell structure outside the assembling, the ease of assembly operation also can conveniently strengthen the enclosure assembling space.

Another purpose of the utility model provides a kind ofly can effectively locate the inner lead shell mechanism, the situation that the solder joint of avoiding external force to pull being caused gets loose.

For achieving the above object, the utility model adopts following technical scheme to realize:

The connector shell package assembly comprises loam cake and lower cover, and both set up jointly for movable button, are respectively equipped with wire casing in the rear end of loam cake and lower cover, two wire casings butt joint double team lead, and on the inner surface of wire casing, suitably be provided with lug boss or depressed part.

Described lug boss is to carry over the convex tendon that the wire casing inner surface distributes.

Described lug boss is the protruding thorn that carries over wire casing inner surface interval or continuous distribution.

The wire casing stage casing of described loam cake and lower cover is respectively equipped with interval trough, and the wire casing front and back end is separated.

Protruded out hook and reference column in the face of covering of loam cake, be respectively equipped with hanging platform and location hole, realized movable the fastening with this in the corresponding position of lower cover; Outer peripheral face in reference column is axially arranged with the key bar, key bar and location hole interference fit.

The shell that the utility model provides comprises upper and lower covers, and adopts movable button to set up jointly, and the ease of assembly operation can strengthen the enclosure assembling space, and simple in structure, makes easily.

The utility model advantage again is suitably to be provided with lug boss or depressed part on the inner surface of wire casing, during assembling, the lead pressurized then outer peripheral face of insulating barrier holds to go into depressed part by lug boss roof pressure or distortion back, it is flexible to limit lead with this, be that the outside is pullled also and can not had influence on the inner lead welding position, keep stable welding.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further specified:

Fig. 1～4 are depicted as the utility model one example structure schematic diagram, described connector shell package assembly, comprise loam cake 10 and lower cover 20, set up jointly for movable button between the two, rear end in loam cake 10 and lower cover 20 is respectively equipped with

wire casing

11 and 21, wear for lead, and assembling back two wire casings butt joint double team lead, lug boss or depressed part on the inner surface of

wire casing

11 and 21, suitably be provided with.

Shown in Fig. 1～4, this enforcement is to be provided with lug boss 111 on the inner surface of wire casing 11, and this lug boss 111 is for carrying over the convex tendon that the wire casing inner surface distributes, and corresponding also is provided with similar lug boss 211 on the inner surface of wire casing 21.The insulating barrier of cramping lead about two lug bosses during assembling makes the distortion of insulating barrier corresponding site and forms the draw-in groove shape, forms clamping with lug boss, well fix lead, make it not flexible, guarantee the stable of wire bonds end, be unlikely to be subjected to external force to pull and get loose.

Consult shown in Fig. 1～4, the face of covering of loam cake 10 has protruded out hook 13 and reference column 14, is respectively equipped with hanging platform 23 and location hole 24 in the corresponding position of lower cover 20, and hook 13 articulates with hanging platform 23, and reference column 14 is pegged graft with location hole 24, realizes movable the fastening with this.Hook 13 is carried over to tip hook cross section by root and diminishes, and it is thicker promptly to link up with 13 roots, the intensity foot, and fastness is good, and it is thinner to extend to the interlude of gib head, has favorable elasticity, reaches hook 13 and well articulates performance.During assembling, hook 13 stretches into lower cover 20 and is mounted on the hanging platform 23, the realization upper and lower covers is combined into one, the cooperation of reference column 14 and location hole 24, the effect of playing location and installation and strengthening being connected is axially arranged with key bar 141, key bar 141 and location hole 24 interference fit in the outer peripheral face of reference column 14, can further strengthen connection, it is more firm and difficult loosening or get loose that upper and lower covers is connected.This structure overcomes one-body molded and defective wave soldering, obtains the comparatively package assembly of handled easily, and the structure design that can conveniently strengthen the enclosure assembling space according to this, be that shell can suitably be widened overall dimension, obtain abundant inside assembling space, be beneficial to welding operation, improve assembling quality.

Consult shown in Figure 5, above-mentioned

lug boss

111 and 211 also can be designed to carry over the protruding thorn of wire casing inner surface interval or continuous distribution, the one-body molded making of protruding thorn and shell, thrust the insulating barrier of lead during assembling by protruding thorn, reach fixing cord with this, make it non-telescoping pulling, guarantee being welded to connect of lead.

Consult shown in 6, also can do the depressed part design on the wire casing 11 of upper and lower covers and 21 the inner surface,

depressed part
