Electric connector
[technical field]
The utility model refers to a kind of electric connector that is used to electrically connect microphone and circuit board especially about a kind of electric connector.
[background technology]
The electric connector structure that is used to electrically connect electronic components such as microphone and loud speaker now adopts the pattern that has insulating body and be contained in the plurality of conductive terminals in the insulating body, for example U.S. Pat 6,146, a kind of electric connector shown in 156, it comprises an insulating body and at least one conductive solder sheet, described insulating body is roughly rectangular, comprise end face, bottom surface and four sidewalls, insulating body has the storage tank that runs through end face and bottom surface, and offer the groove of accommodating that is positioned at storage tank one side at the end face of insulating body, this accommodates groove and storage tank is interconnected, described conductive solder sheet comprises the contact site of main part and autonomous body one lateral bending Qu Yanshen, aforementioned body portion is across the storage tank of insulating body, and corresponding being inserted into accommodate in the groove, and contact site stretches in the described storage tank, and aforementioned body portion is provided with some salient points, interfere mutually between these salient points and the above-mentioned madial wall of accommodating groove, for the fixing of conductive solder sheet in insulating body provides retain strength.
Yet, after plug that should electric connector is inserted, plug can produce the power that compresses to the contact site of conductive solder sheet, this compresses tries hard to recommend the moving conductive bonding pad and outwards moves, at this moment, salient point on the conductive solder sheet can and above-mentioned madial wall of accommodating groove between interfere, thereby stop the conductive solder sheet outwards to move, but in the course of time, the corresponding above-mentioned salient point of the madial wall place of accommodating groove can produce wearing and tearing, cause salient point that the retain strength that conductive solder sheet main part provides is descended, may cause the main part of conductive solder sheet outwards to move a segment distance, and then make between the contact site of plug and conductive solder sheet and can not be in contact with one another, thereby influenced the use of this electric connector.
Given this, be necessary to design a kind of new electric connector to address the above problem in fact.
[utility model content]
The technical problems to be solved in the utility model is a kind of electric connector that can guarantee overall structure stability of design.
The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, comprise insulating body and be assembled in the interior conducting terminal of insulating body, insulating body has sidewall and is concaved with on sidewall accommodates groove, the corresponding above-mentioned groove of accommodating of conducting terminal is provided with main part, and this main part is provided with and above-mentioned holding parts of accommodating the groove interference, and the corresponding holding parts of the groove place of accommodating of insulating body is provided with the accommodation section.
Compared with prior art, the utlity model has following advantage: accommodating of insulating body is provided with the accommodation section that holds holding parts in the groove, the fixing of conducting terminal in insulating body can be strengthened in this accommodation section, prevent that the situation of displacement from appearring in the main part of conducting terminal, thereby guaranteed the integrally-built stability of electric connector.

[embodiment]
Below, will describe in further detail the utility model in conjunction with the accompanying drawings.
Please refer to Fig. 1 to Fig. 3, the utility model electric connector 100 is used for plugging with microphone plug (not shown), and it comprises an insulating body 1 and 2 conducting terminals 2 that are contained in the insulating body 1.
The roughly rectangular setting of insulating body 1, it comprises the first side wall 13 second sidewall 14 relative with other two that the end face 11 that is parallel to each other and bottom surface 12, two are relative.Be respectively equipped with the storage tank 131 that sets to the concave on the first side wall 13, each storage tank 131 is through to bottom surface 12 downwards, and on bottom surface 12, be respectively equipped with opening (not shown), and the opening part that each storage tank 131 is positioned at bottom surface 12 is extended with the collar flange 121 with storage tank 131 concentrics downwards respectively, each flange 121 contact with bottom surface 12 around also extend a projection 122 downwards, and the height that extends less than flange 121 of the height that extends of this projection 122.On the position of described each storage tank 131 end thereon on the throne respectively across being provided with parallel with end face 11 and bottom surface 12 groove 132 of accommodating, this is accommodated groove 132 and is interconnected with storage tank 131, and above-mentioned madial wall of accommodating groove 132 is provided with accommodation section 133, above-mentionedly accommodates the degree of depth that the degree of depth that groove 132 extends internally extends internally less than above-mentioned storage tank 131.In addition, above-mentioned second sidewall 14 is provided with holding section 141 respectively on the both ends of its lengthwise, and the groove 132 of accommodating that these holding sections 141 are adjacent on the first side wall 13 is connected.
Each conducting terminal 2 is by the metal material punch forming, comprises corresponding above-mentionedly accommodating main part 21 that groove 132 is provided with, bending two location divisions 22 of extension respectively and by main part 21 bending extensions and be located at contact site 23 between two location divisions 22 by main part 21 lengthwise two ends.Wherein, main part 21 is provided with some holding parts 211, described holding parts 211 can be located at the upper surface or the lower surface of main part 21, also can be provided with by the end extension of main part 21 near contact site 23, described holding parts 211 is to be contained in the accommodation section 133 of insulating body 1, and described accommodation section 133 can change according to the change in location of above-mentioned holding parts 211 in the position that insulating body 1 is accommodated in the groove 132.Each conducting terminal 2 also comprises the weld part 24 of being located at each location division 22 end, and this weld part 24 is positioned on the bottom surface 12 of insulating body 1, and with above-mentioned projection 122 same planes, and contact with the part side of projection 122.
During assembling, the main part 21 of each conducting terminal 2 is across the storage tank 131 of insulating body 1 and corresponding is inserted into above-mentioned accommodating in the groove 132, the contact site 23 of conducting terminal 2 stretches in the storage tank 131 of insulating body 1, and on the corresponding respectively holding section 141 that is fastened in insulating body 1 both sides, the location division 22 of conducting terminal 2.
During use, the flange 121 of microphone plug by electric connector 100 inserted, make microphone plug contact to compress and get final product with the contact site 23 of above-mentioned conducting terminal 2.
In order to reach the purpose that prevents that conducting terminal 2 from being withdrawed from by insulating body 1, the utility model electric connector 100 can be taked other execution mode according to actual needs except above-mentioned execution mode.For example: conducting terminal and insulating body is one-body molded; Or the holding parts of conducting terminal is set to the structure of reversed acanthoid, and the holding parts that is this kind structure can be accommodated the direction horizontal-extending of groove towards insulating body by a side of conducting terminal main part, and the corresponding above-mentioned holding parts of the groove place of accommodating of insulating body is provided with the accommodation section; Or the number of conducting terminal is set to one or more.Therefore, protection range of the present utility model should be not limited to the content that execution mode discloses, and comprises various do not deviate from replacement of the present utility model and modifications, is the present patent application claim and contains.
