Abstract
The utility model relates to a base of an annular common mode choke. The base of the annular common mode choke comprises a base body in a rectangle shape. Two buckles used for fixing an inductance sheath are arranged on the middle of the base body. The base body is further provided with four through holes corresponding to inductance pins. Four reinforcing ribs are fixed on the base body, and the reinforcing ribs are respectively arranged between every two through holes. At each through hole, an annular rubber guiding hole is formed in one side of the base body in an extending mode, and a boss is arranged on the other side of the base body in an extending mode. Each through hole is communicated with the rubber guiding hole and the boss. The base of the annular common mode choke is capable of facilitating control of a location and dosage of dispensing, and effectively improving finished product quality and overall aesthetic.
Description
Technical field
The utility model relates to a kind of annular common mode inductance that is installed in the power circuit, the base that uses on the especially annular common mode inductance.
Background technology
The annular common mode inductance often is used in and suppresses electromagnetic interference (EMI) in the various power circuits.In the industry, existing annular common mode inductance (as shown in Figure 1) is by the magnetic core in the sheath 20, sheath 20, insulation inserted sheet 30, consist of around enamelled wire 40 and the base 10 in sheath 20 outsides; This base 10 (as shown in Figure 2) is rectangle, and on four angles of base 10, all has through hole 80; Enamelled wire 40 around sheath 20 outsides passes through hole 80, forms the pin 70 of inductance; The middle part of base 10 is provided with two buckles 60 fixing with sheath 20; Also be provided with four reinforcements 90 on the base 10, and each reinforcement 90 is all between two through holes 80; Fixing by epoxide-resin glue 50 between pin 70 and the base 10.Adopt the base of this kind structure, fixedly the time, all be not easy control for the some glue position of epoxide-resin glue and glue consumption, the glue amount is poor with having lacked steadiness, becomes flexible easily, and the glue amount has been used many and not only wasted material cost, also can affect the attractive in appearance of finished product; And, also very high for the soldering tin technique requirement of four pins, in case depainting is clean not, will cause the pin scolding tin under the base rough, not only affect the normal use of inductance, also can reduce quality of finished and the overall appearance degree of inductance.
The utility model content
The utility model purpose is that a kind of glue position, control point and consumption be convenient to is provided in order to overcome the deficiencies in the prior art, improves the base of the annular common mode inductance of quality of finished and overall appearance degree.
For achieving the above object, the technical solution adopted in the utility model is: a kind of base of annular common mode inductance comprises the rectangular base pedestal; The middle part of described base body is provided with the buckle of two fixed inductance sheaths; Also have four through holes corresponding with the inductance pin on the described base body; Also be fixed with four reinforcements on the described base body, and reinforcement is located at respectively between per two through holes; Described each through hole is extended with annular in a side of base body and leads the glue hole, and opposite side extends a boss, and through hole all connects and leads glue hole and boss.
Preferably, described reinforcement all with lead the glue hole and link to each other.
Preferably, described boss is rectangle, and lays respectively on four angles of base body.
Preferably, all have the U-lag that connects with through hole on the described boss.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
The base of a kind of annular common mode inductance of the utility model scheme is led the glue hole by what set up, makes invocation point glue position and glue consumption obtain effective control, has not only saved material cost, has also greatly improved some glue quality; Simultaneously, at the boss that the base body opposite side increases, Effective Raise the scolding tin quality of pin, when improving inductance quality of finished and overall appearance degree, also greatly improved the quality of production and production efficiency.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of annular common mode inductance in the prior art;
Accompanying drawing 2 is the structural representation of the base of annular common mode inductance in the prior art;
Accompanying drawing 3 is the stereogram of the base of annular common mode inductance of the present utility model;
Accompanying drawing 4 is the stereogram of another angle of base of annular common mode inductance of the present utility model;
Wherein: 1, base body; 2, buckle; 3, reinforcement; 4, through hole; 5, boss; 6, U-lag; 7, lead the glue hole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Adopt the base of annular common mode inductance of the present utility model, utilization is set up leads glue hole 7, the pin of base body 1 and inductance is carried out a glue fix, and makes invocation point glue position and glue consumption obtain effective control, not only save material cost, also greatly improved some glue quality; Simultaneously because the boss setting that the base body opposite side increases, Effective Raise the scolding tin quality of pin, greatly improved inductance quality of finished and overall appearance degree.In addition, the base of annular common mode inductance of the present utility model, it is simple in structure, has made things convenient for assembling and the manufacturing of inductance finished product, Effective Raise the quality of production and production efficiency.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
Claims (4)
1. the base of an annular common mode inductance, comprise the rectangular base pedestal, the middle part of described base body is provided with the buckle of two fixed inductance sheaths, also have four through holes corresponding with the inductance pin on the described base body, also be fixed with four reinforcements on the described base body, and reinforcement is located at respectively between per two through holes, it is characterized in that: described each through hole, be extended with annular in a side of base body and lead the glue hole, opposite side extends a boss, and through hole all connects and leads glue hole and boss.
