Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, a kind of manufacture method of USB connector that can double-side plug-in, comprises the following steps:
Step 1, upper terminal 31 is carried out to injection mo(u)lding for the first time; This step main purpose is that four contacts of the inserted terminal of upper terminal 31 are fixed.
Step 3, radium-shine good conducting terminal is carried out to injection mo(u)lding for the second time.The plastic body of USB connector and terminal basic forming after quadric injection mould.
Wherein, between described step 2 and step 3, also comprise: the material strip in lower terminal 32 is cropped.After described step 3, also comprise: the material strip on upper terminal 31 is cropped.The material strip that crops upper terminal 31 and lower terminal 32 has also just completed the body making of USB connector, the work of cutting is divided into two steps and operates the operation that can facilitate injection moulding for the second time.
About the step of cutting material strip, also can disposable after step 3 completes the material strip in upper terminal 31 and lower terminal 32 be cropped.This step can decide according to the Design of Dies of injection moulding for the second time.
Wherein, also comprise: the product cropping after material strip is carried out to electric circuit inspection, if circuit turn-on enters next operation; If short circuit, discards or repairs this product.The product completing is carried out to electric circuit inspection and can effectively avoid problematic finished product to come into the market, affect the use of product and the prestige of company.
Wherein, also comprise: the product of circuit turn-on is carried out to the installation of rear plug, the medial surface of rear plug and the angle of conducting terminal are less than 15 degree.
Wherein, also comprise: shell is assembled on the product that installs rear plug.
The manufacture method of USB connector that can double-side plug-in of the present invention adopts the mode of twice injection mo(u)lding to process upper terminal 31 and lower terminal 32, prevents from the short circuit phenomenon that may occur in one-shot forming process from effectively reducing the generation of defect ware; The USB connector that adopts the method to make can be considered both forward and reverse directions and at will insertion, and easily by recognition of devices, has effectively avoided the damage of grafting process center tap, very easy to use.
As shown in Figures 2 to 4, a kind of USB connector that can double-side plug-in, comprise shell, plastic body 2 and be embedded at the conducting terminal of plastic body 2, described conducting terminal comprises the upper terminal 31 of being located at plastic body 2 upsides and the lower terminal 32 of being located at plastic body 2 downsides; Described plastic body 2 is also provided with the rear plug 4 of the upper and lower skew of restriction conducting terminal.Wherein, the medial surface of described rear plug 4 and conducting terminal are acute angle.Further, the medial surface of described rear plug 4 and the angle of conducting terminal are less than 15 degree, and best angle angle is 5 degree.When conducting terminal is upwards offset or offsets downward when plugging, the medial surface of rear plug 4 limits its deviation angle, within the scope of the toughness of conducting terminal itself (approximately 5 degree), can effectively prevent like this conducting terminal damage because of the connector that upwards inclined to one side or downward bias causes in plug process.
This can double-side plug-in USB connector can consider both forward and reverse directions and at will insert, and easily by recognition of devices, effectively avoided the damage of grafting process center tap, very easy to use; In addition, this USB connector is simple in structure, volume is small and exquisite.
Wherein, described shell is metal shell.
Further, described metal shell comprises front iron-clad 11 and rear iron-clad 12.Adopt front iron-clad 11 and rear iron-clad 12 to protect respectively USB connector, simple for production, install more for convenience.
Wherein, described plastic cement main body and conducting terminal are secondary injection molding part.The manufacturing process of this USB connector needs first upper terminal 31 to be carried out to injection moulding, then adopts radium-shine technical battery to connect terminal 31 and lower terminal 32, finally again the upper terminal 31 connecting and lower terminal 32 is carried out to secondary injection molding.This connector is made simple, with low cost.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
