Description

Switched coaxial connector

The present invention relates to a coaxial connector, and more particularly to a coaxial connector of a radio frequency switch

In the production process, when the overall assembly is completed, the functional test of each part of the whole machine will be arranged. This test must detect the functions of each part as completely as possible in a short period of time, and the switch will be used to change the transmission path of the electronic signal during the test to check whether the circuits of the electronic device are functionally correct. For example, smart phones, tablets, etc., although the whole machine test can be performed by random sampling, in order to reduce the distortion of these tests and simplify the test operation, at least one coaxial with switching function is installed on the motherboard of these electronic devices. Connector.

For example, the TWX 416247 (Application No.: 100210792) discloses a coaxial connector that exposes a first insulative housing and a second insulative housing that are fastened to each other and assembled to the first insulative housing and the second insulative housing. a terminal and a movable terminal, and a metal casing disposed on a periphery of the first insulative housing and the second insulative housing. Such coaxial connectors are still assembled by mutual assembly, but the structural rigidity of such assembly is relatively unstable, and the assembly steps are The problem is that the cost of the product is relatively high.

In order to overcome the above drawbacks, the present invention provides a coaxial connector with a switch, which is to make the overall structure relatively firm, and to improve the cumbersome steps in the assembly of the product, and to reduce the work time and thus the cost reduction.

The technical solution adopted by the present invention to solve the technical problem is: a coaxial connector with a switch, comprising an insulating body, a movable terminal combined with the insulating body, and a combination of in-mold incident molding technology and insulation Fixed terminal and metal housing of the body. The metal housing is disposed on the insulative housing, and the insulative housing has a main body portion, a convex portion protruding from the main body portion, a receiving hole penetrating the convex portion, and a receiving space formed in the main body portion and the jack, and the movable terminal is inserted The body portion is fixed to the main body of the insulative housing and has a resilient arm extending into the receiving space. The fixed terminal portion is embedded in the main body portion of the insulative housing and has a contact portion extending into the receiving space. The elastic arm of the movable terminal is movable to contact and disconnect with the contact portion of the fixed terminal.

Further, the insulative housing has a terminal slot formed in the body portion, and the terminal slot is in communication with the receiving space. The movable terminal has a fixing portion fixed to the terminal slot, and a bent portion extends from the fixing portion and protrudes from the insulation. In the external movable joint welding portion, the elastic arm extends from the fixing portion.

Further, the fixed terminal has a buried portion embedded in the insulating body, a buried connecting arm bent from the embedded portion and embedded in the insulating body, and a bent extension extending from the end of the embedded connecting arm In the fixed terminal soldering portion of the insulating body, the contact portion is horizontally extended from the embedded portion.

The beneficial effect of the present invention is that the fixed terminal portion is embedded in the insulating body by burying the metal casing and the fixed terminal at the same time, and the metal casing is disposed on the insulating body, and the movable terminal is inserted. The solid structural design is assembled to the insulative body. Through the foregoing design, the use of buried incidence to reduce the use of mutual engagement (ie, using a one-piece insulating body) and the reduction of the sequential assembly design, the overall structure is relatively strong, and improve the cumbersome steps in product assembly. , which is beneficial to reducing the working hours and thus reducing the cost.

As shown in FIGS. 1 to 4, the present invention provides a coaxial connector with a switch, which comprises an insulative housing 1, a movable terminal 2, a fixed terminal 3 and a metal housing 4.

In the present invention, the fixed terminal 3 and the metal casing 4 are first placed in a mold formed by the insulating body 1 by means of an Insert Molding technique, and after the insulating body 1 is molded, The fixed terminal 3 and the metal casing 4 are simultaneously combined on the insulative housing 1.

The insulative housing 1 has a body portion 11 when the molding is completed. a protrusion 12 protruding from the body portion 11 , a socket 13 extending through the protrusion 12 , and a receiving space 14 formed in the body portion 11 (as shown in FIG. 4 ), the insertion hole 13 is connected to the receiving space 14 . In addition, the side end of the main body portion 11 of the insulative housing 1 is further formed with a terminal slot 15 that communicates with the receiving space 14.

The movable terminal 2 has a fixing portion 21, an elastic arm 22 extending from one end of the fixing portion 21, and a movable terminal welding portion 23 which is bent and extended from the other end of the fixing portion 21.

The fixed terminal 3 has an embedded portion 31, a contact portion 32 that extends horizontally from the embedded portion 31, a buried connecting arm 33 that is bent and extended from the embedded portion 31, and a fixed terminal welded portion that is bent and extended from the end of the embedded connecting arm 33. 34.

The metal casing 4 has a sleeve portion 41, a plate portion 42 integrally connected to the bottom end of the sleeve portion 41, and a clip portion 43 which is bent and extended from both end portions of the plate portion 42.

In the above, when the metal casing 4 and the fixed terminal 3 are simultaneously coupled to the insulative housing 1, the metal casing 4 is disposed outside the insulative housing 1, the sleeve portion 41 is sleeved outside the side edge of the convex portion 12, and the plate portion 42 is covered. Provided on the surface of the main body portion 11, the clip portion 43 is interposed between the side end portion and the bottom portion of the main body portion 11.
