Abstract
The utility model discloses a rear sheath for a wiring harness direct insertion-type locking terminal. The rear sheath for the wiring harness direct insertion-type locking terminal consists of a casing pipe, two front retainers and a rear retainer and is characterized in that the front retainers and the rear retainer are bosses arranged on the inner wall of the casing pipe in sequence; the two front retainers are two bosses; the rear retainer is one boss; the connecting line of the two front retainers is vertical to the direction that the casing pipe is inserted into the terminal; and the two front retainers are symmetrically arranged at both sides of the rear retainer. According to the rear sheath for the wiring harness direct insertion-type locking terminal, an electronic connecting wire clipping process, an electronic connecting wire stripping process and a terminal crimping process can be smoothly finished on a full-automatic terminal crimping machine, nesting is convenient, capturing is firm, the production efficiency is increased, and the labor cost is reduced.
Description
Technical field
The utility model relates to Wiring harness terminal and makes the field, particularly a kind ofly conveniently is inserted in, the rearmounted sheath of the reliable wire harness direct plugging-in of screens terminal with lock.
Background technology
Wire harness is the connecting part that connects each electric equipment in the circuit, is made up of insulated terminal sheath, binding post, lead and insulation wrapper material etc.Terminal jacket is to be enclosed within the metal terminal outside, plays the insulation protection effect.The wire harness production process is such: first: burst at the seams, confirm lead, stripping area of bed; Second: compression joint technique, but general lead need pass just crimping behind the terminal jacket earlier, and it need be pre-installed earlier on lead and return crimping again from the prepackage station then; The the 3rd: packaging technology.But pass earlier behind the terminal jacket just crimping like this operation be because the head of common direct plugging-in terminal jacket is big, afterbody is little; So must be through sheath above the lead earlier crimp type terminal again, sheath to the terminal outside of pulling back at last; But this process operation is more; The sanction line of whole power line, wire stripping, terminal crimping must separately be carried out, and are unfavorable for automation equipment production, and disarray core easily.Service speed is slow, efficient is not high.
Summary of the invention
The utility model purpose is to above-mentioned technical disadvantages, provides a kind of wire harness direct plugging-in terminal with lock rearmounted sheath, can first crimp type terminal overlaps sheath again and operates in proper order, conveniently is inserted in, screens is reliable.
The rearmounted sheath of a kind of wire harness direct plugging-in terminal with lock; Form by sleeve pipe, preceding screens, back screens; It is characterized in that: screens before said, back screens are the boss that places internal surface of sleeve pipe successively; Preceding screens is that two boss, back screens are a boss, two vertical and sleeve pipe insertion terminal directions of preceding screens line, and two preceding screens are symmetrically placed in screens both sides, back.
The material of said sleeve pipe, preceding screens, back screens is that flexible PVC (polyvinyl chloride) soaks to mould and is made.Terminal jacket uses the flexible PVC material to process; Has very strong pliability and elasticity; Be inserted in the soft characteristics of quoting direct insertion terminal jacket with lock itself in the process; Preceding screens boss was overlapped straight cutting terminal end face, and terminal was enclosed within and recovered original contour structures under the situation that loses external force this moment, and screens and end face, back screens and straight cutting terminal dead bolt are realized interlocking before utilizing.
Said back screens is 0.5～1.5mm apart from two preceding screens line vertical intervals.Make interlock fit tight like this.
The screens insertion end has the oblique angle before said.It is more smooth and easy when sheath has the oblique angle to insert.
This make insertion more smooth and easy, said before screens insertion end oblique angle be 30～60 °.
The beneficial effect of the utility model is: the sheath of this structure can be enclosed within above the terminal under the situation that the crimping of direct plugging-in terminal elder generation is accomplished again; Encapsulation speed is fast; Bayonet socket place lock-bit is firm, and the wire harness manufacturing process is simpler, effectively avoids quality problems and enhances productivity.
Description of drawings
Accompanying drawing 1 is the profile of the utility model.
Accompanying drawing 2 is the cross-sectional view of the utility model.
Accompanying drawing 3 is a kind of direct insertion terminal crimping structure sketch map of the utility model.
Among the figure, 1 is sleeve pipe, and 2 is preceding screens, and 21 is the oblique angle, 3 be the back screens, 4 for sheath inlet, 5 for the terminal front end, 6 for the terminal rear end face, 7 for the terminal dead bolt, 8 for pressure contact portion, 9 be lead.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
Like Fig. 1, shown in Figure 2; The rearmounted sheath of a kind of wire harness direct plugging-in terminal with lock; Preceding screens 2, back screens 3 are the boss that place sleeve pipe 1 inwall successively; Before screens 2 be that two square boss, back screens 3 are a square boss, two preceding screens 2 lines of centres insert the direction of terminal perpendicular to sleeve pipe 1, two preceding screens 2 are symmetrically placed in screens 3 both sides, back.
The material of sleeve pipe 1, preceding screens 2, back screens 3 is that flexible PVC (polyvinyl chloride) soaks to mould and is made.Said back screens is 0.5～1.5mm apart from two preceding screens line vertical intervals.Make interlock fit tight like this.
Preceding screens 2 insertion ends have oblique angle 21, and oblique angle 21 is 30～60 °.
As shown in Figure 3, adopt the utility model sheath to make in the terminal process, lead does not insert sheath earlier, and it comprises terminal front end 5, terminal rear end face 6, terminal dead bolt 7, pressure contact portion 8, lead 9 after the crimping.
Insert sheath inlet 4 to described terminal front end 5 again; Sheath preceding screens 2 in the process of being inserted in is in terminal rear end face 6, terminal lock 7 is pushed up in back screens 3; Preceding screens 2 and terminal rear end face 6, back screens 3 are locked 7 mutual realization interlockings with terminal, thereby realize being inserted in the effect of screens.
Through above execution mode, must overlap sheath, the problem of back crimp type terminal earlier when having solved Wiring harness terminal production; Use the utility model when making the process of Wiring harness terminal, can make and cut out the completion swimmingly on full-automatic terminal crimping connector of line, wire stripping, these operations of terminal crimping, is inserted in simply, and lock-bit is firm, has improved production efficiency, has reduced cost of labor.
