Description
[technical field]
The utility model is relevant a kind of electric connector, refers to a kind of electric connector with plate putting machine especially.
[background technology]
The voice electric connector is widely used in the electrical equipment of generation sound effects such as broadcast receiver, recorder, television set and combination audio, and it mainly provides the effect that voice signal transmits between two systems.In recent years, development along with various miniature electronic devices such as mobile phone, walkman and multimedia type personal computer etc., the application of voice electric connector on the miniature electronic device just day by day popularized, and the various voice electric connector structure designs that are useful on the different electronic installations have appearred, relevant existing design sees also United States Patent (USP) the 6th, 123,580,5, cases such as No. the 82207507th, 192, No. 228 and TaiWan, China patent application.Existing voice electric connector mainly includes insulating body, it is typically provided with the main part of the spliced eye of tool hollow circular cylinder, be used for inserting for the voice plug, the suitable flexible contact portion of several conducting terminal tools is then protruded outside this spliced eye annular inner surface, with with the conducting of voice plug butt, and conducting terminal respectively is extended with the end pin to insulating body, welds in the corresponding welding hole to insert on the circuit board.Except that conducting terminal, also be provided with the terminal that is exclusively used in ground connection, in the hope of reaching the effect of eliminating electrostatic charge and electromagnetic interference.
Yet relevant existing design is to adopt through hole weldering mode to be welded on the circuit board mostly, and this obviously is inapplicable for all extremely limited miniature electronic device of board area and inner space.Though and also occur at present the voice electric connector of SMD LED surface-mount device LED (SMT), but the most structure of the conducting terminal of this type electric connector is comparatively complicated, so no matter be SMT welding or through hole welding, electric connector all may fall down from motherboard when welding reflow for the second time running into.
For overcoming above-mentioned shortcoming, can on the shading member of electric connector, design plate putting machine, common being seen plate putting machine is to be two-way clasp form, and same two-way clasp is to insert in the same holding hole of circuit board.But the size of the holding hole that matches with two-way clasp is all bigger, the confined space of circuit board that this has designed significant wastage.So, a kind of plate putting machine of novel electric connector need be provided.
[summary of the invention]
The purpose of this utility model is to provide a kind of electric connector, and its plate putting machine not only can firmly be held on the circuit board, but also can make circuit board have enough wiring space.
Electric connector of the present utility model includes insulating body, some signal terminals, shading member and plate putting machine, wherein some signal terminals are contained in the insulating body, and it is outer to electrically connect with circuit board to extend insulating body, shading member is coated on the insulating body outside, plate putting machine is connected with shading member, this plate putting machine includes a pair of holding parts, each holding parts all has an interference bump that can match with the holding hole on the circuit board and holding parts is connected to connecting portion on the shading member, wherein the bearing of trend of the interference bump on two holding parts is opposite, when two holding parts all insert in the holding hole of circuit board, wherein the interference bump of a holding parts matches with the preceding hole wall of corresponding holding hole, the interference bump of another holding parts then matches with the back hole wall of another holding hole, like this, what can make that two holding parts provide fore-and-aft direction grabs the plate function, and electric connector firmly is immobilizated on the circuit board.
Compared with prior art, the plate putting machine of the utility model electric connector comprises two holding parts, it is interfered respectively in two holding hole that are immobilizated in circuit board, and electric connector firmly was retained on the circuit board, can save the confined space on the circuit board again.

Fig. 2 is the location diagram of the utility model electric connector and circuit board.
Fig. 3 is the right view after the combination of the utility model electric connector and circuit board, and it has disclosed the relation that the holding parts that is positioned at the shielding casing right side matches with the holding hole of circuit board.
Fig. 4 is the left view after the combination of the utility model electric connector and circuit board, and it has disclosed the relation that the holding parts that is positioned at the shielding casing left side matches with the holding hole of circuit board.
[embodiment]
See also shown in Figure 1ly, the utility model electric connector 1 includes insulating body 2, some signal terminals 3, shading member 4 and holding parts 5.
See also shown in Figure 1, insulating body 2 slightly is a rectangular body, its front side surface has protruded out a connection-peg 21 forward, be provided with a spliced eye 22 in this connection-peg 21, use for banjo connector (not shown) butt joint and plant, its both side surface all outwards protrudes out some fixture blocks 24, some signal terminals 3 are embedded in the insulating body 2, in order to electrically connect with banjo connector (not shown), the bottom surface portions that signal terminal 3 protrudes out insulating body 2 is a contact feet 31, like this, signal terminal 3 can be soldered on the circuit board.Shading member 4 is the metal shell of half-surrounded, the upper wall 41 that it includes two side 40 and connects the two side, the two side 40 of shading member 4 is equipped with some bayonet sockets 400 of the corresponding fixture block 24 of accommodating insulating body 2, the bottom of two side 40 has extended to form a pair of holding parts 5 downwards, each holding parts 5 all has an interference bump 51 that can match with the holding hole 60 on the circuit board 6 and holding parts is connected to connecting portion 50 on the sidewall 40, but the bearing of trend of the interference bump 51 of two holding parts is opposite.Above-mentioned two holding parts are the plate putting machine of the utility model electric connector.
See also Fig. 2 to shown in Figure 4, when shading member 4 was coated on the insulating body 2, each fixture block 24 was contained in the corresponding bayonet socket 400.When the utility model electric connector was installed on the circuit board, holding parts 5 inserted in the corresponding holding hole 60 of circuit board 6, and contact feet 31 is welded on the circuit board.
The bearing of trend of the interference bump 51 of holding parts 5 is opposite, so, when two holding parts 5 all insert in the holding hole of circuit board, wherein the interference bump 51 of a holding parts matches with the preceding hole wall 61 of corresponding holding hole, the interference bump 51 of another holding parts then matches with the back hole wall 62 of another holding hole, like this, what can make that two holding parts provide fore-and-aft direction grabs the plate function, and electric connector 1 firmly is immobilizated on the circuit board 6.
