Description

The Subminiature microwave connector

Technical field

The utility model is relevant connector, and especially relevant socket is the Subminiature microwave connector that is welded on the circuit board.

Background technology

A kind of scolding tin microminiature connector is arranged on the market, and the bottom of the socket 10 of this connector (seeing also shown in Figure 1) is to be welded on the circuit board of notebook computer, PDA(Personal Digital Assistant), mobile telephone mobile phone etc.; And plug 20 (seeing also shown in Figure 2) can be plugged on the socket 10, and its other end is to be connected to antenna as the mobile telephone mobile phone with holding wire, with connection signal.This socket 10 has a metal shell 11, and its lower end is in conjunction with an insulator 12; This insulator 12 stretches into shell 11 inside and forms a protruding end 121 in middle body; This protruding end 121 internal junction unification male terminal 13, the outside that insulator 12 and shell 11 are stretched out for demihull shape in the lower end 131 of this male terminal 13, its upper end 132 is rolled into tubulose, and tool arc end 133.This plug 20 has a metal shell 21, and this housing 21 is in conjunction with an insulator 22; The hollow bulb 221 of this insulator 22 is in conjunction with a female terminal 23 (seeing also Fig. 3 shows), this female terminal 23 by two relatively and the contact 231 that separates a bit of distance formed.When this plug 20 is plugged on the socket 10, be male terminal 13 both sides that two contacts 231 of the female terminal 23 of plug 20 are socketed on socket 10, two signal ends are conducted; And housing 21 is socketed on shell 11 outsides, and two earth terminals are conducted.On business terminal 13 only is contacting also built on the sand of two wire with the contact jaw of female terminal 23, when circuit board is used or is moved along with electronic product and rocks, easily cause between two-terminal because of contacting shakiness and influence the quality of signal transmission, or cause disconnected news phenomenon because of coming off of two-terminal contact jaw.

Seeing also Fig. 4, shown in Figure 5, when making the socket of this connector, is the male terminal 13 with male terminal strip 130, places the centre (as shown in Figure 5) of shell 11 hollows of shell strip 110, places then in the mould and penetrates formation insulator 12 with plastic material.Afterwards, cut off being connected of lower end 131 and brace 111 and strip, promptly become as Fig. 6, socket 10 shown in Figure 7.The brace 111 of this socket 10 is as the usefulness of fixed housing 11 when making.The guide card 112 that is extended by shell 11 two bottom sides is only the usefulness that is used to be welded on the circuit board as ground connection.This brace 111 protrudes in the outside of insulator 12, easily touches it and be close to other electronic building brick and cause short circuit when assembling.And these brace 111 cut edges are very sharp, easily hurt the finger of assembler when assembling.See also shown in Figure 5ly,, when ejection formation insulator 12, easily make shell 11 produce skew, make male terminal can not place the centre of shell 11, cause defective products because of shell 11 only connects shell strips 110 by brace 111.And when cutting off brace 111, make the shell 11 and the junction of brace 111 be subjected to the strength of single direction, easily make shell 111 distortion, cause defective products.

See also Fig. 2, shown in Figure 8, this plug 20 is when assembling, and its female terminal 23 and coaxial line (not drawing among the figure) are the medium pores of putting into housing 21 211 that are vertical angle together with insulator 22.Then, the inside conductor of coaxial line is welded or is held on the end face 232 of female terminal 23.Because the end face 232 of female terminal 23 there is no any block, in conjunction with the inside conductor of coaxial line the time, very difficult control inside conductor places the length of end face 232, and is difficult for firm inside conductor is welded on the end face 232.If only the mode with clamping is fixed in inside conductor on the end face 232, when circuit board is rocked or be mobile, easily cause inside conductor to break away from the phenomenon of end face 232, and can't transmission signals.

Cause many shortcomings of making on going up and using for improving problem on the above-mentioned connector construction, and the fraction defective can reduce product and make the time, manufacturing cost saved.And making the male terminal and the firm combination of female terminal of connector, transmission signals that can be more stable is finished the utility model eventually after the creator studies again and again.
