[0002] The audio control system connector in the prior art generally includes an injection molding block and a guide. The injection molding block is formed at one time, and the guide is installed in the injection molding block that is formed at one time. Since the injection molding block that is formed at one time is large in volume, it is easy to cause damage due to shrinkage and deformation of the plastic part. The resulting poor positioning of the guideline and uneven needle height

Embodiment Construction
[0011] Such as figure 1 , figure 2 , image 3 As shown, an embodiment of the audio control system connector of the present invention includes a primary injection molding block 3, an appearance injection molding block 4 and two rows of guides, and the two rows of guides are successively installed in the guide hole provided by the primary injection molding block 3. The primary injection molding block 3 that is filled with guideline carries out secondary injection molding as core mold and forms appearance injection molding block 4 outside primary injection molding block 3.
[0012] The processing method of the audio control system connector mentioned above is first to carry out an injection molding in an injection mold to form an injection block 3; then insert the first row of pins 1 into a joint spring, and then use tooling to insert the first row of pins 1 Press it into the first row of needle holes provided by the primary injection block 3, bend it and push it to the corres...

The invention discloses an audible control system connector with accurate square needle position and regular needle height as well as a processing method thereof. The audible control system connector comprises a one-time injection molding block, an appearance injection molding block and two rows of square needles which are sequentially arranged in a square hole arranged on the one-time injection molding block, and the one-time injection molding block filled with the square needles is taken as a core die to carry out secondary injection molding so that the appearance injection molding block is formed outside the one-time injection molding block. The processing method comprises the following steps of: carrying out one-time injection molding in a one-time injection molding die to form the one-time injection molding block; installing all the square needles in the square needle hole arranged on the one-time injection molding block; and finally placing the one-time injection molding block filled with the square hole as the core die in an appearance die, carrying out secondary injection molding and forming the appearance injection molding block outside the one-time injection molding block. By the design of the one-time injection molding block, the whole thickness of a plastic part is reduced, and the problems of bad displacement, irregular needle height, and the like caused by shrinkage and deformation of the plastic part due to the thickness, and the like can be prevented.
Description
technical field [0001] The invention relates to an audio control system connector used in an automobile audio module and a processing method thereof. Background technique [0002] The audio control system connector in the prior art generally includes an injection molding block and a guide. The injection molding block is formed at one time, and the guide is installed in the injection molding block that is formed at one time. Since the injection molding block that is formed at one time is large in volume, it is easy to cause damage due to shrinkage and deformation of the plastic part. The resulting position of the guideline is poor and the needle height is not uniform. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an audio control system connector with accurate guideline position and neat needle height and its processing method. [0004] In order to solve the above-mentioned technical problems, the technical sol...
