Abstract
Disclosed is a crystal head, which comprises a tegment riveting part with a riveted press sheet, and takes the tegment riveting part as a basis and forms a core thread groove part by forward extending, a gold plaque clamped with a thread core is arranged at the front end of the core thread groove part, a tegment riveting cavity is arranged in the tegment riveting part, a plurality of core thread grooves are arranged in the core thread groove part, the tegment riveting cavity is communicated with the core thread grooves, a step surface at the joint of the tegment riveting part and the core thread groove part is taken as a benchmark, a core thread groove inlet is arranged on the plane extending inwards with the step surface in the range of plus and minus 3mm, and the core thread groove inlet is connected with the tegment riveting cavity by an inclined plane. The crystal head can effectively prevent plastic of the crystal head from entering the core thread grooves of the crystal head when in injection moulding.
Description
Technical field
The utility model relates to a kind of crystal head that netting twine connects that is used for.
Background technology
Existing crystal head, extremely shown in Figure 8 as Fig. 6, it is outer by riveting portion 10 to generally comprise band riveting sheet 110, based on described outer by riveting portion 10, extend to form heart yearn slot part 20 forward, front end at heart yearn slot part 20 is provided with the gold plaque 30 that is used for the core clamping, outside outside described, being provided with in the riveting portion 10 by riveting chamber 120, in described heart yearn slot part 20, be provided with many heart yearn grooves 210, communicated with described heart yearn groove 210 by riveting chamber 120 outside described, the import 220 of described heart yearn groove with described outer by riveting chamber 120 by generally being to link to each other by cambered surface 40, this crystal head is after with cable and crystal head crimping, generally can pass through injection molding way, annotated into plastics with outside described by riveting chamber 120 remaining space,, because this crystal head project organization is unreasonable, when injection moulding, this partly plastic be not all be retained in described outer by in the riveting chamber 120, but some plastics can enter in the described heart yearn groove 210 along cambered surface 40, so, cause in heart yearn slot part 20 parts and also have a part of plastics, like this, cause with the made netting twine of such crystal head on the one hand and have certain weak point in appearance, on the other hand because after the plastics of high temperature enter heart yearn groove 210, can cause crystal head to produce to break or crackle occurs, cause the substandard products crystal head.
Summary of the invention
The purpose of this utility model be to society provide a kind of when avoiding crystal head in injection moulding its plastics enter crystal head in the heart yearn groove of crystal head.
The technical solution of the utility model is: a kind of crystal head is provided, comprise that band riveting sheet is outer by riveting portion, based on described outer by riveting portion, extend to form the heart yearn slot part forward, front end at the heart yearn slot part is provided with the gold plaque that is used for the core clamping, outside outside described, being provided with in the riveting portion by the riveting chamber, in described heart yearn slot part, be provided with many heart yearn grooves, communicated with described heart yearn groove by the riveting chamber outside described, with described outer be benchmark by the step surface of riveting portion and described heart yearn slot part intersection, be provided with the import of heart yearn groove in the positive and negative 3 millimeters scope in the plane that extends internally with described step surface, the import of described heart yearn groove is linked to each other by the inclined-plane by the riveting chamber outward with described.
Described gold plaque comprises three heart yearn contact heads, and wherein the basal plane of Zhong Jian described plane of heart yearn contact head and gold plaque is in a certain angle.Described angle is preferably in 8 degree.
Near described step surface, be provided with at least one reinforcement.
The utility model since adopted with described outer be benchmark by the step surface of riveting portion and described heart yearn slot part intersection, in the positive and negative 3 millimeters scope in the plane that extends internally with described step surface, be provided with the import of heart yearn groove, import of described heart yearn groove and the described outer structure that is linked to each other by the inclined-plane by the riveting chamber, so the utility model can avoid crystal head its plastics when injection moulding to enter effect in the heart yearn groove of crystal head effectively.

Embodiment
See also Fig. 1, Fig. 2 and Fig. 3, it is a kind of crystal head, a kind of crystal head, comprise that band riveting sheet 11 is outer by riveting portion 1, based on described outer by riveting portion 1, extend to form heart yearn slot part 2 forward, front end at heart yearn slot part 2 is provided with the gold plaque 3 that is used for the core clamping, outside outside described, being provided with in the riveting portion 1 by riveting chamber 12, in described heart yearn slot part 2, be provided with many heart yearn grooves 21, communicated with described heart yearn groove 21 by riveting chamber 12 outside described, it is characterized in that: with described outer step surface 13 by riveting portion 1 and described heart yearn slot part 2 intersections is benchmark, be provided with heart yearn groove import 22 in the positive and negative 3 millimeters scope in the plane that extends internally with described step surface 13 14, the import 22 of described heart yearn groove is linked to each other by inclined-plane 15 by riveting chamber 12 outward with described.Like this, can avoid effectively when injection moulding, the plastics that heat is melted enter the problem in the heart yearn groove 21.Be provided with at described heart yearn slot part 2 back sides and be used for the card 4 that is connected with female seat.Be provided with at least one reinforcement 16 near described step surface 13, this reinforcement 16 can prevent effectively that crystal head from cracking in its side.
See also Fig. 4 to Fig. 5, described gold plaque 3 comprises three heart yearn contact heads 31, and wherein Zhong Jian heart yearn contact head 311 is to a lateral buckling, and it is in a certain angle to form the basal plane 32 of described plane and gold plaque 3.Described angle 33 is preferably in 8 degree.The gold plaque of this structure can be a contact with contacting of heart yearn with traditional gold plaque 3, changes into the heart yearn contact head 31 of middle heart yearn contact head 311 with both sides to be clipped on the described heart yearn, and the contact of formation face has improved the contact stabilization of gold plaque 3 with heart yearn.
