Abstract
The utility model relates to a plugging connector, which mainly comprises an insulating casing and a plurality of conductive terminals, wherein, the conductive terminals which are in a long rod shape and are fixedly embedded in the insulating casing are provided with output ends and plugging ends with holding parts. When a master base connector is inserted with the plugging connector, contacting parts of a master base terminal on the master base connector can be clamped and butted with the holding parts of the conductive terminals of the plugging connector, and consequently, contacting area is increased, the reliability of telecommunication transmission is enhanced, and the withdrawal force of the terminals which are assembled is enhanced.
Description
The utility model is a kind of connectors, is meant a kind of connectors that can increase contact area between connectors and female seat connector conducting terminal, have high withdrawal force especially.
It is one rectangular shaft-like that the existing connectors that can be plugged in the female seat connector, the male terminal on it are, when it and female seat connector plug, realize transmitting the effect of telecommunication between the male terminal on female seat terminal on the female seat connector and the connectors by point-to-area contacting, as United States Patent (USP) the 5th, 456,612,4,230,387,4,655,517,5,370, No. 540 etc.The connectors relevant with the utility model comprises insulation shell 11 and some male terminals 12 as shown in Figure 1, and this male terminal 12 is a rectangular shaft-like and build-in in insulation shell 11, and it comprises inserted terminal 121 and output 122.See also shown in Figure 2, when connectors 1 and a female seat connector 2 plug, female seat terminal 21 is to overlap on the inserted terminal 121 of the male terminal 12 that is sandwiched in connectors 1 with its two folders contact arm 22, this female seat terminal 21 is provided with circular-arc protuberance 221 in two folder contact arms, 22 leading section appropriate locations and connects with male terminal 12, reducing the insertion force of female seat terminal 21, and realize the suitable effect that grips.And the elastic clip of the contact jaw 121 of 221 pairs of male terminals 12 of protuberance of the folder contact arm 22 by female seat terminal 21 is pulled and is contacted, and realizes the telecommunication conduction.But, promptly be connected to the contact jaw 121 of male terminal 12 with the protuberance 221 of female seat terminal 21 because this connectors 1 is to contact in the circular arc mode with female seat connector 2.The mode of this some contact causes the loose contact of 21 of male terminal 12 and female seat terminals easily, and withdrawal force required after 2 of this connectors 1 and female seat connectors connect is littler than insertion force, if need to be applied to the often product of plug, then very easily make the folder contact arm 22 of female seat terminal 12 produce elastic fatigue, thereby the closeness of contact between the reduction terminal, even cause female seat terminal 21 loosening and come off, influence the telecommunication laser propagation effect of terminal.
The purpose of this utility model provide a kind of contact better, have higher withdrawal force and more be applicable to the connectors that needs regular plug product.
The purpose of this utility model is achieved through the following technical solutions: connectors includes insulation shell and several conducting terminals at least, and its conducting terminal is a rectangular shaft-like and build-in in insulation shell, includes inserted terminal and output.Inserted terminal appropriate location at conducting terminal is provided with holding parts, when connectors is plugged on the female seat connector, the contact site of female seat terminal can fasten in the holding parts of this connectors conducting terminal, be to have formed the contact effect of face between the protuberance of holding parts and female seat terminal of conducting terminal inserted terminal with face, thereby increase its contact area, and the clip between the holding parts of protuberance by the female seat terminal and conducting terminal has improved the withdrawal force after the terminal assembling.
Compared with prior art, this reality has novel advantage to be: this connectors can increase contact area and the chucking power between the female seat terminal of its conducting terminal and female seat connector, except that making terminal be easy to the clip location, increase the reliability of electrically contact, also have the withdrawal force of increase and life-saving and effect easy to use.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the outside drawing of existing connectors.
Fig. 2 is the assembled sectional view of existing connectors and female seat connector.
Fig. 3 is the outside drawing of the utility model one embodiment.
Fig. 4 is the assembled sectional view of the utility model one embodiment and female seat connector.
As shown in Figures 3 and 4, connectors 3 of the present utility model comprises insulation shell 31 and several conducting terminals 32 etc., insulation shell 31 is elongated housings of one injection molding, it has a plugging surface 311, is provided with the terminal containing slot 312 of some perforations of fixing conducting terminal 32 on plugging surface 311.Conducting terminal 32 is elongated rod shape, and is mounted in the terminal containing slot 312, includes inserted terminal 321 that plugs with female seat connector (not shown) and the output 322 that is communicated with circuit board (not shown) telecommunication.Offer holding parts 323 in the appropriate position of inserted terminal 321 along the ring side face, this holding parts 323 is the groove shape, fastens so that plug with female seat connector 2.And holding parts 323 also can be circular groove or the trapezoidal groove of full Zhou Kaishe.
When connectors 3 and female seat connector 2 plug, female seat terminal 21 is sandwiched on the inserted terminal 321 of conducting terminal 32 by its two folders contact arm, 22 covers, the leading section of 21 liang of folders of this female seat terminal contact arm 22 is provided with circular-arc protuberance 221, this protuberance 221 clips in the holding parts 323 of conducting terminal 32, borrow the concave surface of the holding parts 323 of conducting terminal 32 inserted terminals 321 to contact, thereby make both cooperations with the face way of contact with the convex surface of the protuberance 221 of female seat terminal 21 folder contact arms 22.Like this, except the contact area of 21 of the female seat terminals of the conducting terminal 32 that can increase connectors 3 and female seat connector 2, increase the reliability of telecommunication conduction and make things convenient for outside the clip location between terminal.Be that clip is in the groove 323 of conducting terminal 32 also because of the protuberance 221 on the female seat terminal 21 folder contact arms 22, its amount of interference is bigger, make and to need bigger withdrawal force when female seat connector 2 extracted, thereby can guarantee that female seat connector 2 is difficult for coming off because of loosening, more be applicable to the product of regular plug.
