The main purpose of the utility model is that overcome existing connector there are the defects of, and provide a kind of connector Combination simplifies preparation process, and saves human cost, improves yield rate, thus more suitable for practicality, and in industry Utility value.

The purpose of this utility model and its technical problem is solved using following technical scheme to realize.

A kind of connector combination, including basic connector and pcb board, wherein,

The basis connector is provided with the first contact, and the pcb board is provided with and first contact corresponding first Wiring hole.

Further, the shell of the basic connector is square box shaped case, and first contact is arranged on the square box The outside of shape shell.

Further, the basic connector further includes the second contact, and the second contact of the basis connector is arranged on The inside of the square box shaped case.

Further, first contact at least two, and the size of each first contact is different, described first Wiring hole is provided at least two, and corresponding with the size of each first contact respectively.

Further, first wiring hole is bellmouth.

Further, the bottom of the basic connector is provided with ribbed stiffener.

Using above-mentioned technical proposal, following technique effect can be realized：

1）, basic connector and pcb board combination overcome existing for complicated connector that moulding process is difficult, finished product is qualified The problem of rate is low, and cost can be reduced；

2）, basic connector bottom ribbed stiffener effectively enhance the intensity of plastic shell, further improve its use Service life；

3）, the first wiring hole for bellmouth or uses various sizes of first contact worker carrying out to distinguish circuit During assembling can easily efficiently precise positioning basis connector and pcb board, be less prone to the situation of circuit wrong.

Specific embodiment

Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken, To according to the utility model proposes connector combination its specific embodiment, feature and its effect, be described in detail as after.

As shown in Fig. 2, the utility model discloses a kind of connector combination, including basic connector 1 and pcb board 2, In, basic connector 1 is provided with the first contact 11, pcb board 2 be provided with 11 corresponding first wiring hole 21 of the first contact, lead to It crosses the first contact 11 and the connection of circuit is completed in 21 grafting of the first wiring hole, be additionally provided with the second wiring hole 22 on pcb board 2, use In the extraneous circuit of connection.

As shown in figure 5, the shell of basic connector 1 is square box shaped case 14, the first contact 11 is arranged on square box shaped case Outside, specifically, being provided projectingly in 14 bottom of square box shaped case, and be arranged in parallel with bottom.

Further, basic connector 1 further includes the second contact 12,12 side of being arranged on of the second contact of basic connector 1 The inside of box-shaped casing 14, for communication line.

Further, the first contact 11 at least two, and the size of each first contact 11 is different, the first wiring hole 21 Be provided at least two, and corresponding with the size of each first contact 11 respectively, due to the first contact 11 for it is multiple when, filling Timing easily occur it is with the wrong location cause cable connection error, and the correctness for differentiating connection circuit is not only time-consuming and laborious, and pole It is made a fault, and causes yield rate low, therefore when the first contact 11 is multiple, by being designed and sized to for each first contact 11 Different size, and the first corresponding wiring hole 21 is merely able to be inserted into corresponding first contact 11, therefore worker is in assembling It is not required to spend more time that assembling can be completed.

Preferably, in order to realize the assembling of pcb board 2 and basic connector 1, the first wiring hole 21 is bellmouth, is only existed The one side of first wiring hole 21 of larger open, the first contact 11 can realize insertion, and opposite direction, can not be inserted into, Therefore assembling can be completed without the excessive judgement of progress during worker assembles.

Further, in order to increase the intensity of basic connector 1, the bottom of basic connector 1 is provided with ribbed stiffener 13, into One step improves the service life of basic connector 1.

The above descriptions are merely preferred embodiments of the present invention, and not the utility model is made in any form Limitation, although the utility model has been disclosed with preferred embodiment as above, be not limited to the utility model, it is any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model Hold, any simple modification, equivalent change and modification that foundation the technical essence of the utility model makees above example, still Belong in the range of technical solutions of the utility model.
