The template is characterized in that the template is provided with a group of fixing holes in a matrix arrangement at intervals: the bottom center position department of fixed orifices seted up a contact pin spacing groove respectively downwards, the lateral wall of fixed orifices on constitute and have a round internal thread. The displacement of the insulator and the contact pin is effectively prevented, and the production efficiency and the qualification rate of products are greatly improved.
Description
Technical Field
The utility model belongs to the technical field of electronic components anchor clamps, concretely relates to mould is used in sintering of single core connector of radio frequency.
Background
The radio frequency single-core connector is also called a radio frequency single-core coaxial glass insulator, is a common one in electronic components, generally comprises a shell, an insulator and a contact pin, can form a thread on the shell so as to facilitate fixed connection in order to facilitate the installation of the radio frequency single-core connector, and the radio frequency single-core connector needs to be assembled manually in the production process of the shell, the insulator and the contact pin and then is placed in a mold for sintering and fixing. At present, a mould for sintering is generally in a structure that a hole is formed in a flat plate, a radio frequency single-core connector is directly placed in the fixed position of the hole and is sintered, even the connector is directly placed in a plate for sintering, the situation that an insulator is inclined or sinks due to heating protrusion and contact pins often occurs in the sintering process, because the temperature of a sintering furnace is improperly controlled or temperature difference exists in some areas, once the situation occurs, the possibility that the whole radio frequency single-core connector is scrapped often means, and great loss is caused to manufacturers.
In view of the above, there is a need for a sintering mold for a radio frequency single core connector, which has a simple structure and low cost, and can effectively fix the connector and prevent the displacement of the insulator and the pin. The applicant has therefore made an advantageous design, in the context of which the solution to be described below is made.
Disclosure of Invention
The utility model aims at providing a mould is used in sintering of single core connector of radio frequency helps improving the fixed knot who moulds and connector to construct and prevents that insulator and contact pin from taking place the displacement, is favorable to improving the qualification rate of production efficiency and product.
In order to achieve the above purpose, the utility model provides a technical scheme is: the utility model provides a mould is used in sintering of single core connector of radio frequency, includes a template, the template on the interval set up and be the matrix arrangement and have a set of fixed orifices, its characterized in that: the bottom center position department of fixed orifices seted up a contact pin spacing groove respectively downwards, the lateral wall of fixed orifices on constitute and have a round internal thread.
In a specific embodiment of the present invention, the middle portions of the left, middle and right three positions of the mold plate are respectively provided with a limiting hole.
In another specific embodiment of the present invention, the sum of the depths of the fixing hole and the pin spacing groove is smaller than the thickness of the template.
In another specific embodiment of the present invention, the depth of the fixing hole is smaller than the height of the external thread on the surface of the housing end of the connector, and the diameter of the external thread matches the diameter of the internal thread.
