no. 1 Embodiment approach

[0036] Such as figure 1 with figure 2 As shown, the coaxial connector 1 has a housing 10, an internal contact 20 and an external contact 30.

[0037]

[0038] Such as figure 1 with figure 2 As shown, the housing 10 is integrally formed of an electrically insulating material (for example, synthetic resin). The housing 10 is composed of a rear portion 10a and a front portion 10b. The rear portion 10a has a generally rectangular parallelepiped shape, and the front portion 10b has a generally cylindrical shape having an axis perpendicular to the longitudinal direction of the rear portion 10a. The thickness of the front portion 10b is formed to be thicker than the thickness of the rear portion 10a (refer to figure 2 ).

[0039] The rear portion 10a is formed with a first groove portion 11a having a semicircular cross-section and opening on the rear side, and extending so as to coincide with the axial direction of the coaxial cable 50 and the longitudinal direction of the rear port...

no. 2 Embodiment approach

[0066] Next, refer to Figure 8 , The second embodiment will be described. Regarding the present embodiment, only the structure of the locking portion and the holding portion is different from the aforementioned first embodiment, and therefore the description of the structure common to the first embodiment is omitted. Such as Figure 8 As shown, in this embodiment, the respective locking portions of the locking portions 23 protruding in the width direction of the conductor clamping arm 22 are bent to the conductor placing portion 21 side. In addition, in each of the locking portions of the locking portion 23, a stopper 23a extending in a direction perpendicular to the bending direction and a protruding portion (barb) 23b protruding in the same direction are sequentially formed toward the front end.

[0067] On the other hand, in the conductor mounting portion 21, the holding portions 25 and 25 into which the bent locking portions 23 are inserted are formed corresponding to the nu...

no. 3 Embodiment approach

[0069] Next, refer to Picture 9 , The third embodiment will be described. Regarding the present embodiment, only the structure of the locking portion is different from the aforementioned first embodiment, and therefore the description of the common structure with the first embodiment is omitted. Such as Picture 9 As shown, in this embodiment, the respective locking portions of the locking portions 23 protruding in the width direction of the conductor clamping arm 22 are bent to the conductor placing portion 21 side. In addition, barbs 23c are protrudingly formed on each side edge of both side edges of the bent locking portion 23. On the other hand, in the housing 10, a slot-shaped holding portion 12 is formed, and by bending the conductor holding arm 22, the barb 23c of the locking portion 23 is pressed into the holding portion 12. The size in the front-rear direction of the respective holding portions 12 and 12 is set to be equal to or less than the size of the locking port...

Abstract

A coaxial connecter and a method for assembling the same are provided, in which there is little variation in the amount of holding an inner conductor between connection terminals and the connection between the inner conductor and the connection terminals is achieved with high reliability. The coaxial connector includes a housing, an inner contact, and an outer contact. The inner contact is secured to the housing and includes a conductor mounting portion and a conductor holding arm with a lock. The conductor holding arm is integrally formed with the conductor mounting portion. The outer contact is secured to the housing, as well. Either the housing or the conductor mounting portion is provided with a holding portion into which the lock is press-fitted when the conductor holding arm is folded toward the conductor mounting portion.

Description

Technical field [0001] The present invention relates to a coaxial connector used in information equipment such as mobile phones, notebook personal computers, and small electronic equipment such as household appliances and an assembly method thereof. Background technique [0002] Conventionally, in such a coaxial connector, the internal conductor of the coaxial cable and the connection terminal of the coaxial connector are often welded. However, if there is a difference in the amount of solder used for the connection between the internal conductor and the connection terminal, there is a problem that the characteristic impedance deviates from a desired value. In addition, since lead is often used for solder, it is preferable not to solder the coaxial cable from the environmental point of view at the time of disposal. [0003] Therefore, as a coaxial connector that does not use solder when connecting the inner conductor and the connection terminal, there is proposed Picture 10 with ...
