Abstract
The invention discloses an anti-cracking category-5 (CAT5) crystal head. The anti-cracking CAT5 crystal head comprises an insulation shell; a plurality of wiring holes which are parallel to each other are formed at the front end of the insulation shell; a wire slot which is communicated with each wiring hole is formed at the front end of each wiring hole; a metal wire pressing sheet is inserted into each wire slot; a cavity communicated with each wiring hole is formed in the back end of the insulation shell; and a glue baffle structure is formed between the cavity and each wiring hole and is matched with an injection strip of a polyvinyl chloride (PVC) injection molding die in order to separate the cavity from each wiring hole. The glue baffle structure is matched with the injection strip of the PVC injection molding die to separate each wiring hole from the cavity when injection molding is performed on the crystal head through the PVC injection molding die, so that the PVC sol is only injected into a blank part in the cavity but cannot be injected into the blank parts of the wiring holes; and therefore, the aim of preventing the PVC sol from crushing into the crystal head to effectively prevent the crystal head from cracking can be fulfilled.
Description
Technical field
The present invention relates to crystal head technical field, be specifically related to a kind of anti-cracking type CAT5 crystal head.
Background technology
Existing CAT5 crystal head is an insulation shell (being generally PC housing), and the front end of described insulation shell is provided with several through wires holes be parallel to each other, and the front end of each through wires hole is respectively provided with a wire inserting slot be communicated with it; Further, a metal pressure-ray film is respectively plugged with in each wire inserting slot; The rear end of described insulation shell is provided with a cavity be communicated with described through wires hole.Wire penetrates in insulation shell from described cavity, and the bottom of wire inserting slot is arrived through described through wires hole, under normal circumstances, when being contained in the wire bottom the metal pressure-ray film in wire inserting slot and insertion wire inserting slot after pressing, just inject the plastic cement melt (i.e. so-called MOLDING forming process) of PVC material, now, vacant position in through wires hole and cavity will be injected into PVC melt, because PVC melt is inner at the state undershoot water inlet crystal-tipped of HTHP, its expansive force is very large, so in the shaping rear phenomenon that crystal head breaks that easily occurs of crystal head.
Meanwhile, because the chemical composition of PVC melt and existing CAT5 crystal head is incompatible, exacerbate further shaping after crystal head fracture phenomena.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of PVC melt can be made the least possible pour the inner thus anti-cracking type CAT5 crystal head effectively avoiding crystal head to break of crystal head.
For solving the problem, the technical solution adopted in the present invention is as follows:
A kind of anti-cracking type CAT5 crystal head, comprise insulation shell, the front end of described insulation shell is provided with several through wires holes be parallel to each other, and the front end of each through wires hole is respectively provided with a wire inserting slot be communicated with it; Further, a metal pressure-ray film is respectively plugged with in each wire inserting slot; The rear end of described insulation shell is provided with a cavity be communicated with described through wires hole; A glue-guard structure is also provided with between described cavity and through wires hole; Described glue-guard structure is for coordinating the note bar of PVC injection mold described cavity and through wires hole to be separated.
Preferably, described insulation shell is PC housing.
Preferably, the quantity of described through wires hole is eight, and accordingly, the quantity of described wire inserting slot and metal pressure-ray film is eight.
Preferably, described glue-guard structure comprises the through hole and draw-in groove that match with the note bar size of PVC injection mold; Described through hole is arranged on the bottom in the insulation shell region between cavity and through wires hole; Described through hole is communicated with described cavity and through wires hole; Described draw-in groove is arranged on the top in the insulation shell region between cavity and through wires hole, and described draw-in groove is communicated with described cavity and through wires hole, and described draw-in groove is also just to described through hole; During use, described note bar passes described through hole and is connected in described draw-in groove.
Compared to existing technology, beneficial effect of the present invention is:
Anti-cracking type CAT5 crystal head of the present invention by being provided with a glue-guard structure between cavity and through wires hole, when using PVC injection mold to carry out injection moulding to crystal head, the note bar of PVC injection mold is coordinated through wires hole and cavity to be separated, thus make PVC melten gel only inject vacant position in cavity, and can not be injected in the vacant position of through wires hole, finally reach make PVC melt the least possible to pour crystal head inner thus effectively avoid the object that crystal head breaks.
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is the front view of anti-cracking type CAT5 crystal head of the present invention more preferably embodiment;
Fig. 2 is the rearview of Fig. 1;
Fig. 3 is the A-A direction structure schematic diagram of Fig. 1.
Embodiment
As shown in Figure 1 to Figure 3, anti-cracking type CAT5 crystal head of the present invention, comprises insulation shell 1, and the front end of described insulation shell 1 is provided with several through wires holes 2 be parallel to each other, and the front end of each through wires hole 2 is respectively provided with a wire inserting slot be communicated with it 3; Further, a metal pressure-ray film (not shown) is respectively plugged with in each wire inserting slot 3; The rear end of described insulation shell 1 is provided with a cavity 4 be communicated with described through wires hole 2; A glue-guard structure is also provided with between described cavity 4 and through wires hole 2; Described glue-guard structure is for coordinating the note bar (not shown) of PVC injection mold to be separated with through wires hole 2 by described cavity 4.
Particularly, described insulation shell 1 is PC housing.
Particularly, the quantity of described through wires hole 2 is eight, and accordingly, the quantity of described wire inserting slot 3 and metal pressure-ray film is eight.
Particularly, described glue-guard structure comprises the through hole 5 and draw-in groove 6 that match with the note bar size of PVC injection mold; Described through hole 5 is arranged on the bottom in insulation shell 1 region between cavity 4 and through wires hole 2; Described through hole 5 is communicated with described cavity 4 and through wires hole 2; Described draw-in groove 6 is arranged on the top in insulation shell 1 region between cavity 4 and through wires hole 2, and described draw-in groove 6 is communicated with described cavity 4 and through wires hole 2, and described draw-in groove 6 is also just to described through hole 5; During use, described note bar passes described through hole 5 and is connected in described draw-in groove 6, thus described cavity 4 is separated with through wires hole 2, PVC melten gel is made only to inject vacant position in cavity 4, and can not be injected in the vacant position of through wires hole 2, finally reach make PVC melt the least possible to pour crystal head inner thus effectively avoid the object that crystal head breaks.
