Description
Technical field
The present invention relates to electric connector field, especially relate to a kind of to be used cooperatively with the contact pin of various outside dimensions
The variable electric connector of jack internal diameter.
Background technology
In recent years, with communication, the fast development of the industry such as electrically, the application field of electric connector also continuous quilt
Widen, used as the core component of electric connector, contact assembly also gradually tends to variation.
Contact assembly is made up of the contact pin contacting piece and jack contact for matching each other, when in use, contact pin
One in contact and jack contact is assembled in plug casing, and another is assembled in Socket casing, along with
Plug plugging together and separating with socket, and contact assembly completes to be switched on and off circuit.
In traditional contact assembly, jack is usually to be made up of the metallic sheath of a conduction, and contact pin is then by conduction
Metal bar construction, when plugging together, contact pin be inserted into the endoporus of jack and and jack contact, so as to complete to circuit
Conducting.In order to ensure between contact pin and jack reliable contacts and to be conductively connected, the chi at the contact pin end being adapted to jack
Very little to have very strict requirement, usual tolerance otherwise just occurs contact pin contacting piece and jack contact not over 0.1mm
Contact engaging and separating force is not enough between part（Contact pin contacting piece external diameter is too small）Or cannot plug together（Contact pin contacting piece external diameter is excessive）Phenomenon, from
And the problem that electric signal cannot transmit can be caused to occur, this problem is needing the radio frequency (RF) coaxial connector of high-quality transmission signal
Upper embodiment it is especially prominent.
In order to avoid the appearance of above mentioned problem, the contact pin contact of the multiple electric connectors used at same electric fracture
When the model of part is different, then need to be equipped with the jack contact of corresponding size specification according to the different size of contact pin contacting piece, enter
And increasing various electric connectors containing different inner diameters size jack, this just causes increasing for connector at same position, when
When the size difference of the contact assembly of different size is smaller, the problem for also easily occurring obscuring.
The content of the invention
It is an object of the invention to provide a kind of jack that can be used cooperatively with the contact pin contacting piece of various outside dimensions
The variable electric connector of internal diameter.
In order to solve the above problems, the variable electric connector of jack internal diameter uses following technical scheme：Jack internal diameter is variable
Electric connector, including insulator and fixing assembling jack on insulator, jack includes sheath and is assemblied in sheath
Conductive sleeve, with front end as inserted terminal, the jacket wall of conductive sleeve is provided with spring pawl to sheath, and the front end of the spring pawl is located at the set of conductive sleeve
On wall, rear end is gradually drawn close to the center line of conductive sleeve from front to back.
The rear end of spring pawl is provided with the arc bending structure of outward bending.
The rear end fixing assembling of the sheath has rear enclosure, and jack is by rear enclosure and insulator secure fit, the front end of sheath
Turn edge is provided with, conductive sleeve is clamped between the turn edge of sheath and rear enclosure.
The conductive sleeve is C-shaped set.
The spring pawl is integral type structure with conductive sleeve, and the jacket wall of conductive sleeve is provided with resigning hole corresponding with spring pawl.
Because the jack of the variable electric connector of the jack internal diameter has the sheath and conductive sleeve, on the jacket wall of conductive sleeve
Spring pawl is provided with, and the front end of spring pawl is located on the jacket wall of conductive sleeve, and its rear end is from front to back gradually to the center line of conductive sleeve
Draw close, therefore, when in use, jack can be coordinated by its spring pawl with the contact pin contacting piece being adapted to connects circuit, as long as inserting
Needle contact piece is inserted into conductive sleeve, then spring pawl just can with its reliable contacts, therefore, the variable electric connector of the jack internal diameter
Can be used cooperatively with the contact pin contacting piece of various outside dimensions, when in use, it is only necessary to ensure the housing of intermateable connector
Size is unanimously capable of achieving supporting the use for the electric connector and Multiple Type intermateable connector.
Further, the arc bending structure can avoid the sword side of spring pawl end from directly scraping corresponding contact pin contact
Part, can play a part of protection adaptation contact pin contacting piece.
Brief description of the drawings
Fig. 1 is the use state figure of the embodiment of the variable electric connector of jack internal diameter；
Fig. 2 is the cooperation schematic diagram of the jack in Fig. 1 and contact pin；
Fig. 3 is the structural representation of the conductive sleeve in Fig. 2.
Specific embodiment
The embodiment of the variable electric connector of jack internal diameter, as Figure 1-3, the variable electric connector bag of the jack internal diameter
The jack 103 for including housing 101, insulator 102 and being securely fitted in by insulator 101 in housing 101, jack 103 is included
Sheath 11, the conductive sleeve 12 being assemblied in sheath 11 and it is securely fitted in the rear enclosure 13 of the rear end of sheath 11.
Sheath 11 is provided with turn edge with front end as inserted terminal at its front end.Conductive sleeve 12 is C-shaped set, the set of conductive sleeve 12
Wall is provided with spring pawl 14, and the front end of spring pawl 14 is located on the jacket wall of conductive sleeve 12, and rear end is gradually inside from front to back, i.e., to conduction
The center line of set 12 is drawn close, and in the present embodiment, spring pawl 14 is set to one with conductive sleeve 12, and it is from the jacket wall of conductive sleeve 12
Punching, bending and go out so that formd on the jacket wall of conductive sleeve 12 with the corresponding resigning hole of spring pawl 14, when insertion insert
When the external diameter of needle contact piece 15 is larger, spring pawl 14 can be kept under the squeezing action of contact pin contacting piece 15 elasticity return to phase
In the resigning hole answered.In addition, in order to prevent the scratch contact pin contacting piece 15 of spring pawl 14, the rear end of spring pawl 14 is additionally provided with outward bending
Arc bending structure.
Rear enclosure 13 fixes the rear end for being inserted into sheath 11, and on the one hand it play a part of to reinforce sheath 11, on the other hand
Conductive sleeve 12 is held out against in the turn edge of the front end of sheath 11, the fixation to conductive sleeve 12 is realized.
When using the electric connector, shell mechanism and the consistent multiple intermateable connectors of size can be therewith equipped with, be adapted to
The contact pin model of connector can be identical, when contact pin model is smaller（External diameter is smaller）When, spring pawl is touched by its elasticity pressure and inserted
Just the conducting to related circuit can be realized on pin, when contact pin model is larger, spring pawl still can be by elastic deformation come automatic suitable
The outside dimension of contact pin is answered, therefore, the electrical connection that the variable electric connector of the jack internal diameter can be different from various contact pin external diameters
Device is supported the use.
